Publications on thesaurus construction and use

- including some references to facet analysis, taxonomies, ontologies, topic maps and related issues

This is a list of printed and electronic publications about the principles of constructing and using information retrieval thesauri. It is not a list of existing thesauri, although some thesauri have been included when they are good examples or illustrate the results of different approaches to thesaurus construction.

At the end I have given a few references on the following:

I have not yet examined all the articles listed, so in some cases the details and abstracts quoted have come from current awareness services and other sources.

Thesaurus structure and use

About thesauri / Jessica L. Milstead. - [s.l.] : Jelem, 2000.

A brief introduction to what a thesaurus is, why an organisation may need one, and the process of thesaurus construction.

After the dot-bomb : getting Web information retrieval right this time / by Marcia J. Bates. - First Monday, volume 7, number 7, July 2002.

In the excitement of the "dot-com" rush of the 1990's, many Web sites were developed that provided information retrieval capabilities poorly or sub-optimally. Suggestions are made for improvements in the design of Web information retrieval in seven areas. Classifications, ontologies, indexing vocabularies, statistical properties of databases (including the Bradford Distribution), and staff indexing support systems are all discussed. - [Author's abstract]

ASIS thesaurus of information science and librarianship / by Jessica L. Milstead. 150p. ISBN: 0-938734-80-6 Price: $35.00

Related fields such as computer science, linguistics, education, and economics are examined. The thesaurus includes over thirteen hundred preferred terms, 691 nonpreferred terms, and 37 facet indicators. Scope notes and definitions of ambiguous terms are given. Contains an alphabetical listing, a hierarchical listing, and a rotated (KWIC) listing.

Australian pictorial thesaurus (APT). - Sydney : State Library of New South Wales, 2000. - [Accessed 2000-11-04]

"The purpose of the Australian Pictorial Thesaurus is to provide Australian terms for indexing Australian pictorial collections and a controlled vocabulary for searching across image databases on the Internet. It is intended that the APT will become a national standard for describing pictorial materials. All non-abstract topic terms are arranged hierarchically within five narrower terms [categories or tables: events & activities; ideas & concepts; manufactured objects; natural objects; people; places & structures]. Terms for abstract ideas and concepts are arranged following the Dewey Classification Scheme in a separate table [not available on the Web site].

The Australian Pictorial Thesaurus was developed through a joint project sponsored by the National Library of Australia, Australian Museums Online (AMOL) and led by the Council of Australian State Libraries (CASL). CASL is the peak body representing the eight State and Territory Libraries throughout Australia. AMOL is an initiative of the Cultural Ministers Council and its Heritage Collections Council. CASL, AMOL and the National Library are now sponsoring the ongoing management and development of the APT." - [Extracted from Web pages]

Although constructed for the indexing of pictorial material, this is a well-structured general thesaurus of 15,000 terms arranged hierarchically which may be of use for any collection of objects and images. The "about APT" page gives sound and useful advice not only on the use of this thesaurus but on indexing using any thesaurus

Discovering buffalo story robes: a case for cross-domain information strategies / Lyn Elliot Sherwood. - Computers and the Humanities, 1998, vol.32, no.1, p.57-64.

Buffalo Story Robes, a small digital exhibit from Canada's Glenbow Museum, was the inspiration for this author's insights into how to realize the potential of the digital library. Sherwood, the head of the Canadian Heritage Information Network (CHIN) found that this exhibit on the stories of the tribes of the Canadian plains had many related resources in government repositories, archives and libraries. The exhibit represents one small example of a current challenge in the digital environment: how to enable users to find related across domains. Sherwood acknowledges that "each of these communities is bound by its own traditions and classification schema." She asserts that effective access is dependent on increased collaboration among the many disciplines, and recommends looking closely at the role of authorities, thesauri and a process for mapping taxonomies across domains. Perhaps common sense, but essential if we are ever to realize the vision of the digital library as "an organized, selected or managed body of information." - Abstract by Lisa Yesson from Current Cites Vol.9, no.10 October 1998

Essential classification / Vanda Broughton. London : Facet Publications, 2004. - xii, 324p. ISBN 1 85604 514 5.

This paperback was published in October 2004 and and represents the most recent addition to classification text books. The title may be a little misleading as the book also covers subject analysis and word based approaches such as lists of subject headings and thesauri. Thus, the book serves as a rather comprehensive introduction to the whole field of knowledge organization in libraries - with good practical overviews, summaries, exercises, a glossary, an index and a bibliography with suggestions for further reading. - [Extract from review by T.

This practical text examines the criteria relevant to the selection of a subject management system, describes the characteristics of some common types of subject tool, and takes the novice step-by-step through the process of creating a system for a specialist environment. The methodology employed is a standard technique for the building of a thesaurus that incidentally creates a compatible classification or taxonomy, both of which may be used in a variety of ways for document or information management. - [Publishers' Web site]

This text presents an automated method for creating a first-draft thesaurus from raw text. It describes natural processing steps of tokenization, surface syntactic analysis and syntactic attribute extraction. From these attributes, word and term similarity is calculated and a thesaurus is created showing important common terms and their relation to each other, common verb-noun pairings, common expressions, and word family members. The techniques are tested on 20 different corpora ranging from baseball newsgroups, assassination archives, medical X-ray reports, abstracts on AIDS, to encyclopedia articles on animals, even on the text of the book itself. The corpora range from 40,000 to 6 million characters of text, and results are presented for each in appendices. The methods described in the book have undergone extensive evaluation. Their time and space complexity are shown to be modest. The results are shown to converge to a stable state as the corpus grows. The similarities calculated are compared to those produced by psychological testing. A method of evaluation using Artificial Synonyms is tested. Gold Standards evaluation show that techniques significantly outperform non-linguistic-based techniques for the most important words in corpora. This text includes applications to the fields of information retrieval using established testbeds, existing thesaural enrichment and semantic analysis. Also included are applications showing how to create, implement, and test a first-draft thesaurus. - [Synopsis from publisher's Web site.]

Extracting value from automated classification tools : the role of manual involvement and controlled vocabularies / by Kat Hagedorn, Argus Associates. - Ann Arbor, Michigan : Argus Associates, March 2001.

Automated classification tools can't solve today's large-scale web and intranet indexing challenges alone. Neither can humans. But solutions that integrate human expertise with software products such as Interwoven's Metatagger and Autonomy's Categorizer can provide real value and savings. After a brief introduction to automated classification, this white paper discusses the benefits and limitations of manual, automated, and hybrid approaches. It explores the opportunities for leveraging controlled vocabularies and thesauri to produce more effective indexing solutions. - Author's summary

Faceted classification and logical division in information retrieval / Jack Mills. - Library Trends, vol.52, no.3, Winter 2004, p.541-570.

The main object of the paper is to demonstrate in detail the role of classification in information retrieval (IR) and the design of classificatory structures by the application of logical division to all forms of the content of records, subject and imaginative. The natural product of such division is a faceted classification. The latter is seen not as a particular kind of library classification but the only viable form enabling the locating and relating of information to be optimally predictable. A detailed exposition of the practical steps in facet analysis is given, drawing on the experience of the new Bliss Classification (BC2). The continued existence of the library as a highly organized information store is assumed. But, it is argued, it must acknowledge the relevance of the revolution in library classification that has taken place. It considers also how alphabetically arranged subject indexes may utilize controlled use of categorical (generically inclusive) and syntactic relations to produce similarly predictable locating and relating systems for IR. - Author's abstract

From data to knowledge through concept-oriented terminologies : experience with the medical entities dictionary / James J. Cimino. - Journal of the American Medical Informatics Association, 2000, vol.7, p.288-297 . - 29 refs.

Knowledge representation involves enumeration of conceptual symbols and arrangement of these symbols into some meaningful structure. Medical knowledge representation has traditionally focused more on the structure than the symbols. Several significant efforts are under way, at local, national, and international levels, to address the representation of the symbols though the creation of high-quality terminologies that are themselves knowledge based. This paper reviews these efforts, including the Medical Entities Dictionary (MED) in use at Columbia University and the New York Presbyterian Hospital. A decade's experience with the MED is summarized to serve as a proof-of-concept that knowledge-based terminologies can support the use of coded patient data for a variety of knowledge-based activities, including the improved understanding of patient data, the access of information sources relevant to specific patient care problems, the application of expert systems directly to the care of patients, and the discovery of new medical knowledge. The terminological knowledge in the MED has also been used successfully to support clinical application development and maintenance, including that of the MED itself. On the basis of this experience, current efforts to create standard knowledge-based terminologies appear to be justified. - [Author's abstract]

GenThes : a general thesaurus browser for Web-based catalogue systems : a step towards component based catalogue systems / Ralf Nikolai, Ralf Kramer, Marc Steinhaus, Paolo Plini and Bruno Felluga.

Thesauri have been proven means to identify documents in libraries for centuries. In this paper, we show how this approach can be combined with most recent Internet technologies. The Java-based general thesaurus browser GenThes is able to handle several heterogeneous, multilingual thesauri. With the General European Multilingual Environmental Thesaurus (GEMET), GenThes is currently being used with several environmental catalogue systems. Feedback from users reveal that this approach greatly facilitates search and retrieval as compared to free-text only search. Performance which is crucial in Web applications as well has been improved by reducing the transfer volume of data and code. The software architecture of GenThes supports easy configuration and adaption to the individual needs of different systems that it is connected to. Ongoing work as well addresses to use GenThes as a query expansion module for multilingual search in distributed document collections. - [Authors' abstract]. - [Accessed 2001-02-11]

Information retrieval systems offering personalized automated assistance have the potential to improve the searching process. There has been much work in this area for several years on a variety of systems. However, there has been little empirical evaluation of automated assistance to determine if it is of real benefit for searchers. We report the results of empirical evaluation investigate how searchers use implicit feedback and automated assistance during the searching process. Results from the empirical evaluation indicate that searchers typically use multiple implicit feedback actions, usually bookmark - copy. The most commonly utilized automated assistance was for query refinement, notable the use of the thesaurus. We discuss the implications for Web systems and future research. - [Author's abstract]

Multilingual thesaurus construction - integrating the views of different cultures in one gateway to knowledge and concepts / by Michele Hudon. Information Services and Use (ISSN: 0167-5265), vol.17 no.2/3, 1997, p.111-123.

The development of a multilingual thesaurus is more than the "putting together" of several monolingual thesauri. The true multilingual thesaurus offers complete conceptual and terminological inventories for each one of the languages involved; most importantly, to present a fully developed thesauri structure in each language, so that a user consulting the linguistic version most appropriate for her/him gets the same amount of semantic information. General linguistic and specific semantic problems arising in multilingual thesaurus construction are relatively well defined in the various textbooks and in the guidelines covering this area. Much details are provided on the "conceptual equivalence" issues, and various ways of dealing with conceptual divergence are described. But when discussing semantic solutions, display options, management issues, or use of technology, specialists and guidelines seldom, if ever, go as far as commenting on whether or not a particular option is truly respectful of a language and its speakers.
This paper, based on the premise that in a multilingual thesaurus all languages are equal, reviews the options and solutions offered by the guidelines to the developer of specialized thesauri. It also introduces other problems of a sociocultural, and even of a truly political nature, which are a prominent feature in the daily life of the thesaurus designer but with which the theory and the guidelines do not deal very well. It focuses in turn on semantic, managerial, and technological aspects of multilingual thesaurus construction, from the perspective of giving equal treatment to all languages involved. - [Journal abstract]

NISO Z39.19: Standard for structure and organization of information retrieval thesauri / Jessica L. Milstead. Paper presented at the Taxonomic Authority Files Workshop, Washington, DC, June 23, 1998.

Online construction of alphabetic classaurus : a vocabulary control and indexing tool / F. J. Devadason. - Information Processing and Management, vol.21, no.1, 1985, p.11-26.

Classaurus is a faceted hierarchic scheme of terms with vocabulary control features. It is a system of terms having separate hierarchic schedules of the Elementary Categories: Discipline, Entity, Property, and Action, together with their respective Species/Types, Parts and Special Modifiers. Also there are separate schedules for the Common Modifiers: Form, Time, Environment, and Place. Each of the terms in these hierarchic schedules is enriched with synonyms, quasi synonyms etc. The hierarchic schedules constituting the systematic part is supplemented by an alphabetical index of chain entries. Classaurus is used in the formulation of subject headings in general, and in particular, subject headings according to the Postulate based Permuted Subject Indexing (POPSI) language. For the construction of classaurus the POPSI language itself provides guidelines. A set of programs have been developed to construct a classaurus using as input, subject headings formulated according to POPSI language which are enriched with certain codes to denote the different Elementary Categories, their Species, Parts, Special Modifiers and other Common Modifiers of different kinds. The resulting classaurus has hierarchic schedules but terms in an array are arranged only alphabetically. The hierarchic schedules constitute the Systematic part of the classaurus. The system generates an alphabetic Index Part to the Systematic Part, in which for each term its broader terms are kept to its right hand side successively along with a code to denote the schedule to which the term belongs. To find out the position of a term in the Systematic Part, the whole entry for the term in the Alphabetic Part is taken and the sequence of the terms in it is reversed. Using the code for the schedule in the entry, the appropriate hierarchic schedule is selected. The schedule is then searched using the broader terms successively as keys until the term in question is reached, wherein all the hierarchically related terms could be found, including synonyms, quasi-synonyms etc. Both the Systematic Part and the Alphabetical Index Part are printed out for manual reference and also kept as direct access files for on-line access and on-the-spot updating and building up of the classaurus while inputting new subject headings formulated for this purpose. - [Abstract from publishers' web site; full text available for purchase online]

The rise of ontologies or the reinvention of classification / by Dagobert Soergel. - Journal of the American Society for Information Science, 1999. vol.50, no.12, p. 1119-1120.

Classifications/ontologies, thesauri, and dictionaries serve many functions, which are summarized in this note. As a result of this multiplicity of functions, classifications - often called ontologies - are developed in many communities of research and practice. Unfortunately, there is little communication and mutual learning; thus, efforts are fragmented, resulting in considerable reinvention and less than optimal products. - [Author's abstract]

The availability of central reference information as thesauri is critical for correct intellectual access to distributed databases, in particular to digital collections in international networks. There is a continuous raise in interest in thesauri, and several thesaurus management systems have appeared on the market. The issue, how to integrate effectively such central resources into a multitude of client systems and to maintain the consistency of reference in an information network has not yet been satisfactorily solved. We present here a method and an actual thesaurus management system, which is specifically designed for this use, and implements the necessary data structures and management functions. The system handles multiple multilingual thesauri and can be adapted to all semantic thesaurus structures currently in use. Consistency­critical information is kept as history of changes in the form of backward differences. The system has been installed at several sites in Europe. - Authors' abstract

This report examines the use of knowledge organization systems - schemes for organizing information and facilitating knowledge management - in a digital environment.
Knowledge organization systems serve as bridges between a user's information needs and the material in a collection. Examples of such systems include term lists, such as dictionaries; classification schemes, such as ... [the Dewey Decimal Classification]; and relationship lists, such as thesauri. These and other types of knowledge organization systems, which vary in complexity, structure, and function, can improve the organization of digital libraries and facilitate access to their content. -[Publisher's abstract, amended.]

The role and functions of a consultant in thesaurus development are reviewed, with guidance given on when and how a consultant can be selected. The need for a contract is discussed, and the steps of a thesaurus project are outlined. The cost of thesaurus development is seen to be subject to many variables which makes it difficult to estimate accurately, but some guidelines are given. Testing and feedback are important, and the use of a thesaurus requires an ongoing commitment from the client organisation to maintain and develop it to keep pace with change. Ways in which thesaurus development software can be used are discussed, and attention is drawn to the need for interaction between thesaurus developers and user interface designers to allow the benefits of a thesaurus-based information retrieval system to be fully realised.

Thesaurus-enhanced search interfaces / Ali Asghar Shiri, Crawford Revie and Gobinda Chowdhury. Journal of Information Science, 28 (2) 2002, p.111-122.

User interfaces to information retrieval systems play a major role in assisting users to search, browse and retrieve information relevant to their needs. This paper provides a review of a category of information retrieval interfaces that are enhanced by incorporating standard thesauri as part of their searching and browsing facilities. A brief account of the rationale behind the integration of thesauri as search aids in such interfaces is provided, based on research literature related to information searching behaviour, information retrieval interface evaluation, search term selection and query expansion. Two categories of search interfaces enhanced with thesauri are examined: those associated with research-based programmes and commercial web-based interfaces to bibliographic databases. Six commercial web-based databases are compared in terms of their thesaurus interface features. It is concluded that, although the number of thesaurus-enhanced interfaces is growing, few studies have focused on user interaction with these interfaces or fully explored the ways in which they can assist users in the search process. - [Authors' abstract.]

Thesaurus federations: loosely integrated thesauri for document retrieval in networks based on Internet technologies / by Ralf Kramer, Ralf Nikolai, Corinna Habeck. International Journal on Digital Libraries (ISSN: 1432-5012), vol.1 no.2, September 1997, p.122-131

As a result of the distribution of interrelated information over several different information systems, the interconnection of information systems has increased in recent years. However, a purely technical interconnection is insufficient for users who need to find their way to information they are looking for. Thesauri are a proven means to identify documents, e.g., books of interest in a library. For different domains, different thesauri are available, which can be used in information systems as well, e.g., for the indexing and retrieval of data objects. Thus, interconnection of information systems raises the need to integrate related thesauri. Furthermore, recent advances in open operability technologies (World Wide Web, CORBA, and Java) offer the potential for completely new technical solutions for employing thesauri.
This paper presents an approach for integrating multiple thesauri databases. It concentrates on the integration of distributed and heterogeneous thesaurus databases and the integration of multilingual and monolingual thesauri. The software architecture takes advantage of the most advanced Internet and CORBA technology currently available in public domain and in commercial implementations. - [Journal abstract]

A thesaurus interchange format in RDF / B.M.Matthews, K. Miller, M.D.Wilson - Accessed 2003-01-18

If the semantic web using RDF is going to be adopted and assimilated a clear migration path from present technologies to new ones is required. Thesauri are used throughout the information retrieval world as a method of providing controlled vocabularies for indexing and querying. The semantic relations in thesauri are defined in ISO standards. The ISO standards are currently undergoing revision, including the probable introduction of a thesaurus interchange format (TIF). A TIF is proposed represented in RDF which captures the current semantic relations, and which can be used as a step towards the application of more semantically discriminating ontologies. - [Authors' abstract]

Thesauri are used to provide controlled vocabularies for resource classification. Their use can greatly assist document discovery because thesauri man date a consistent shared terminology for describing documents. A particular thesaurus classifies documents according to an information community's needs. As a result, there are many different thesaural schemas. This has led to a proliferation of schema-specific thesaural systems. In our research, we exploit schematic regularities to design a generic thesaural ontology and specify it as a markup language. The language provides a common representational framework in which to encode the idiosyncrasies of specific thesauri. This approach has several advantages: it offers consistent syntax and semantics in which to express thesauri; it allows general purpose thesaural applications to leverage many thesauri; and it supports a single thesaural user interface by which information communities can consistently organise, store and retrieve electronic documents. - Authors' abstract

As initial exploration of programmatic access to KOS with the SKOS API, we developed a pilot PC-based (.NET) Web service client demonstrator application. This was tested on a remote server, which used a different technology platform. Supported by concept caching, it generally achieved a fast enough response for reasonable interaction and suggests that the SKOS API can support client applications of this type. However further refinement of the API is required.
Given foreseeable bandwidth limitations, KOS-specific protocols continue to be needed for efficient services. Future API designs should support the further integration of KOS into rich but responsive mapping and query terminology services. - Authors' conclusions

Vocabulary as a central concept in library and information science / Michael Buckland. - Preprint of paper published in: Digital libraries: interdisciplinary concepts, challenges, and cpportunities.

Arpanac et al. - Zagreb : Lokve, 1999[?]. - ISBN 953-6003-37-6. - pp 3-12.

The nature and role of vocabulary in information systems is examined. "Vocabulary" commonly refers to the stylized adaptation of natural language to form indexes and thesauri. Much of bibliographic access, filtering, and information retrieval can be viewed as matching or translating across vocabularies. Multiple vocabularies are simultaneously present. A simple query in an online catalog normally involves at least five distinct vocabularies: those of the authors; the cataloger; the syndetic structure; the searcher; and the formulated query.

Vocabulary can be defined as the range (or repertoire) of values in any field of bibliographic description and, in a more extended sense, the range of types in a set at any level (word, field, collection, and library). Digital libraries can be represented by a simple recursive model composed of sets ("collections") and two kinds of operation on the sets.

Vocabulary problems are central to the economics of digital libraries because unfamiliar vocabulary reduces search effectiveness. Issues of identity are central to Library and Information Science because of the indexical role of vocabulary. Vocabulary is a central component in digital libraries. Problems inherent in vocabulary help explain the nature and history of conceptions of Library and Information Science. - [Author's abstract]

What are going to be the new vocabulary management and indexing needs of the twenty first century? Synapse Corporation is attempting to identify these needs through discussions with companies and organizations worldwide. Some topics of current interest include: (i) drill-down taxonomies specifically geared to producers of web-based directories - classification structures that combine top-down hierarchical pathways and multifaceted classification principles; (ii) interfaces with automated or computer-assisted indexing systems. ... While much research on natural language processing (NLP), automatic indexing and classification, etc., continues, to date nothing has been developed that can effectively manage and make accessible web information. As more data is continually added to the web universe, and as attempts to integrate intranet data with web information to create a single reference source on a specific desktop, it appears that NLP alone is not the solution. However, a synthesis of NLP and modified thesaurus and classification methodologies seems to hold great promise for effective web searching and navigation in the near future. - [From authors' abstract and summary.]

"... we present an approach for using Web services to interact with controlled vocabularies. Services are implemented within a service-oriented architecture (SOA) framework. SOA is an approach to distributed computing where services are loosely coupled and discoverable on the network. A set of experimental services for controlled vocabularies is provided through the Microsoft Office (MS) Research task pane (a small window or sidebar that opens up next to Internet Explorer (IE) and other Microsoft Office applications). The research task pane is a built-in feature of IE when MS Office 2003 is loaded. The research pane enables a user to take advantage of a number of research and reference services accessible over the Internet. Web browsers, such as Mozilla Firefox and Opera, also provide sidebars which could be used to deliver similar, loosely-coupled Web services." - [From authors' introduction]

The compilation, maintenance, and dissemination of taxonomic authority files has much in common with authority control as conceived and practiced in the library cataloging and information retrieval communities. The purpose of this workshop is to provide a forum in which members of the systematics and library communities can describe their respective domains, and identify the concepts, practices, and technologies that could be shared to promote consistency in the cataloging, indexing, and retrieval of biological information. The two-day workshop consisted of 18 presentations by invited speakers, questions and comments for speakers, and discussion at the end of each session. - Index page

As an example, an appendix defines an XML DTD for thesaurus terms based on the model, and includes an example XML document using that DTD.
This profile does not mandate any relationship between a thesaurus and a database. The model is that terms from any thesaurus database may be used to search any other database (called a target database). - [Introduction]

All about facets and controlled vocabularies / by Karl Fast, Fred Leise and Mike Steckel. - Boxes and arrows, 9th December 2002.

This is the first in a series of articles . . . We intend to explain both facets and the more general concept of controlled vocabularies. We want to make the subject accessible to those who don't have advanced degrees in library and information science. Furthermore, we want to show how these concepts can be applied to solve information architecture problems for the Web and other digital information environments.
The concept of faceted classification is decades old, and controlled vocabularies go back even further. Consequently a great deal has already been written about the subject. But these writings are not always helpful to the practicing Information Architect. Some are too simple, others too academic. Most are hard to find, and many were written decades before this Web thing happened. - [Introduction]

The Essential elements of faceted thesauri / by Louise Spiteri. - Cataloging & Classification Quarterly vol.28, no.4, 1999, p.31-52

The goal of this study is to evaluate, compare, and contrast how facet analysis is used to construct the systematic or faceted displays of a selection of information retrieval thesauri. More specifically, the study seeks to examine which principles of facet analysis are used in the thesauri, and the extent to which different thesauri apply these principles in the same way.
A measuring instrument was designed for the purpose of evaluating the structure of faceted thesauri. This instrument was applied to fourteen faceted information retrieval thesauri. The study reveals that the thesauri do not share a common definition of what constitutes a facet. In some cases, the thesauri apply both enumerative-style classification and facet analysis to arrange their indexing terms. A number of the facets used in the thesauri are not homogeneous or mutually exclusive. The principle of synthesis is used in only 50% of the thesauri, and no one citation order is used consistently by the thesauri. - Author's abstract

"So often we assume that Web sites should be hierarchically organized. We talk about a "home page" that offers "top-level navigation" so that users can "drill down" to the content. It's as if we're programmed to think top down. But what about information that isn't as easily structured this way? Sometimes, content has many attributes that have different importance to different users. A hierarchy assumes everyone approaches these attributes the same way, but that's often not the case." - Introduction.

"I have given a seven- step model for the creation of a faceted classification, and five questions to ask and four principles to follow when building a facet-based web interface. Faceted systems are very powerful, and their increasing popularity on the web is no surprise. They will only become more common, so it is important to design and deploy them well. All the benefits of a faceted classification can be fully realized on the web, giving users power that they have not had with simpler web-based systems or with faceted systems on paper." - Author's conclusion.

The Use of facet analysis in information retrieval thesauri: an examination of selected guidelines for thesaurus construction / by Louise F Spiteri. Cataloging & Classification Quarterly (ISSN: 0163-9374), Vol. 25 No. 1, 1997, p. 21-37.

Facet analysis has been used in the construction of faceted thesauri since the publication of the Information Retrieval Thesaurus of Education Terms in 1968. In spite of the growth of the number of faceted thesauri since then, there appears to be little consensus among thesaurus designers regarding how the principles of facet analysis are to be used in thesauri. An examination of various national and international guidelines for thesaurus construction reveals that they emphasize primarily the construction of alphabetical thesauri, but provide little guidance in the use of facet analysis in thesauri. - [Journal abstract]

Search interfaces that allow for combining terms from multiple facets of a thesaurus or different characteristics of division

There is an important distinction, not always recognised, between the following two approaches. The second of these is better called searching by parameters or characteristics rather than by facets.

  1. Combining multiple facets of a compound subject, such as people, organizations, abstract concepts, places, objects, materials and so on.
  2. Combining multiple characteristics of division of concepts within a single facet, e.g. within a materials facet there may be a concept of wines, subdivided into several arrays, not mutually exclusive, each headed by a node label such as <wines by colour>, <wines by sweetness>, <wines by origin>, <wines by price> and so on.

The International Children's Digital Library (ICDL) is a 5-year research project to develop innovative software and a collection of books that specifically address the needs of children as readers. The search interface allows selection from 13 facets, alone or in combination, with multiple selections from the same facet when required. Needs Java, a broadband connection and a reasonably fast machine with at least 256k memory.

Seamark : the enterprise navigator for digital information and components / Siderean Software, Inc. [2005?].

An example of a search interface for food recipes that combines terms from six possible facets: course, season, main ingredients, cooking method, cuisine and source. Only a single short list of terms is given under each of these, however, and there are no lower hierarchical levels. This appears to be an alternative interface to the Epicurious database referred to above.

Semantic Web environmental directory (SWED) / SWAD Europe, 2004.

A demonstration project of a directory using RDF (resource description framework). Each organisation maintains a web page holding their own data, and these are brought together in this common interface. It is a good example, showing how concepts may be selected from several facets, allowing browsing down to narrower terms within each facet and allowing multiple terms to be chosen from the same facet (overcoming a limitation of the FLAMENCO project listed above). As it is an experimental project, it is not being maintained "on a day to day basis".

Social care online London : Social Care Institute for Excellence (SCIE), Accessed 2006-03-24

An interesting example of a site that displays thesaurus hierarchies and allows multiple selections. A few aspects could be improved, for example: (1) the numbers of postings are not updated dynamically as terms are selected; (2) terms can be pasted into a search box (limited to AND operators) only from the "simple search" interface and not the "advanced search"; (3) related term (RT) links are shown even when there are no related terms to display; (4) it is not possible to display two separate hierarchies simultaneously (though the help file indicates that it is). The site shows good possibilities, though, and if improvements such as those noted above could be implemented it would be one of the best.

This is the commercial product arising from the No Zero Match (NZM) project developed at the University of Bristol. The user interface includes a tree structure against which documents, files or database records can be associated. By allowing these documents to be associated with any number of nodes in the tree, the system provides a means of browsing a faceted classification. An application of the system can be seen at Arkive and a paper describing the system is: 'No Zero Match' browsing of hierarchically categorised information entities / C. A. McMahon and others. - Artificial Intelligence for Engineering Design, Analysis and Manufacturing, vol.16, 2002, p.243-256.

Lists of thesauri

Networked Knowledge Organization Systems (NKOS) have drafted a registry of attributes that may be used when describing thesauri, classifications and other types of knowledge organisation system. A general registry built on these guidelines has not yet been created, but in the meantime the following lists can be used to find many general and specialist thesauri.

The University of Toronto Library maintains a Subject Analysis Systems (SAS) Collection which is the North American Clearinghouse for classification schemes, subject heading lists, and thesauri, and the major world collection in the English language, including multilingual thesauri containing English language sections. These are included in the library catalogue, and records may be retrieved by doing a subject search for "subject headings". Searching for "classification" also retrieves many relevant items.

Topic maps

Metadata? Thesauri? Taxonomies? Topic Maps! : making sense of it all / by Lars Marius Garshol - Oslo : Ontopio, [accessed 2004-03-27]

To be faced with a document collection and not to be able to find the information you know exists somewhere within it is a problem as old as the existence of document collections. Information Architecture is the discipline dealing with the modern version of this problem: how to organize web sites so that users actually can find what they are looking for.
Information architects have so far applied known and well-tried tools from library science to solve this problem, and now topic maps are sailing up as another potential tool for information architects. This raises the question of how topic maps compare with the traditional solutions, and that is the question this paper attempts to address.
The paper argues that topic maps go beyond the traditional solutions in the sense that it provides a framework within which they can be represented as they are, but also extended in ways which significantly improve information retrieval. - [Author's abstract].

The TAO of topic maps : finding the way in the age of infoglut / Steve Pepper. - Oslo : Ontopio, [accessed 2003-01-30]

Topic maps are a new ISO standard for describing knowledge structures and associating them with information resources. As such they constitute an enabling technology for knowledge management. Dubbed "the GPS of the information universe", topic maps are also destined to provide powerful new ways of navigating large and interconnected corpora.
While it is possible to represent immensely complex structures using topic maps, the basic concepts of the model - Topics, Associations, and Occurrences (TAO) - are easily grasped. This paper provides a non-technical introduction to these and other concepts (the IFS and BUTS of topic maps), relating them to things that are familiar to all of us from the realms of publishing and information management, and attempting to convey some idea of the uses to which topic maps will be put in the future. - [Author's abstract].
