- Abstract
- We present three fundamental, interrelated approaches to support multiple access paths to each terminal object in information hierarchies: faceted classification, faceted search, and web directories with embedded symbolic links. This survey aims to demonstrate how each approach supports users who seek information from multiple perspectives. We achieve this by exploring each approach, the relationships between these approaches, including tradeoffs, and how they can be used in concert, while focusing on a core set of hypermedia elements common to all. This approach provides a foundation from which to study, understand, and synthesize applications which employ these techniques. This survey does not aim to be comprehensive, but rather focuses on thematic issues.

- Abstract
- This paper maps the concepts "space" and "dimensionality" in classifications, in particular in visualizations hereof, from a historical perspective. After a historical excursion in the domain of classification theory of what in mathematics is known as dimensionality reduction in representations of a single universe of knowledge, its potentiality will be explored for information retrieval and navigation in the multiverse of the World Wide Web.

- Abstract
- Purpose - The aim of this article is to estimate the impact of faceted classification and the faceted analytical method on the development of various information retrieval tools over the latter part of the twentieth and early twenty-first centuries. Design/methodology/approach - The article presents an examination of various subject access tools intended for retrieval of both print and digital materials to determine whether they exhibit features of faceted systems. Some attention is paid to use of the faceted approach as a means of structuring information on commercial web sites. The secondary and research literature is also surveyed for commentary on and evaluation of facet analysis as a basis for the building of vocabulary and conceptual tools. Findings - The study finds that faceted systems are now very common, with a major increase in their use over the last 15 years. Most LIS subject indexing tools (classifications, subject heading lists and thesauri) now demonstrate features of facet analysis to a greater or lesser degree. A faceted approach is frequently taken to the presentation of product information on commercial web sites, and there is an independent strand of theory and documentation related to this application. There is some significant research on semi-automatic indexing and retrieval (query expansion and query formulation) using facet analytical techniques. Originality/value - This article provides an overview of an important conceptual approach to information retrieval, and compares different understandings and applications of this methodology.

- Abstract
- Various fields, each with its own theories, techniques, and tools, are concerned with identifying and representing the conceptual structure of specific knowledge domains. This paper compares facet analysis, an analytic technique coming out of knowledge organization (especially as undertaken by members of the Classification Research Group (CRG)), with semantic frame analysis, an analytic technique coming out of lexical semantics (especially as undertaken by the developers of Frame-Net) The investigation addresses three questions: 1) how do CRG-style facet analysis and semantic frame analysis characterize the conceptual structures that they identify?; 2) how similar are the techniques they use?; and, 3) how similar are the conceptual structures they produce? Facet analysis is concerned with the logical categories underlying the terminology of an entire field, while semantic frame analysis is concerned with the participant-and-prop structure manifest in sentences about a type of situation or event. When their scope of application is similar, as, for example, in the areas of the performing arts or education, the resulting facets and semantic frame elements often bear striking resemblance, without being the same; facets are more often expressed as semantic types, while frame elements are more often expressed as roles.

- Abstract
- The Bliss Bibliographic Classification is the only example of a fully faceted general classification scheme in the Western world. Although it is the object of much interest as a model for other tools it suffers from the lack of a web presence, and remedying this is an immediate objective for its editors. Understanding how this might be done presents some challenges, as the scheme is semantically very rich and complex in the range and nature of the relationships it contains. The automatic management of these is already in place using local software, but exporting this to a common data format needs careful thought and planning. Various encoding schemes, both for traditional classifications, and for digital materials, represent variously: the concepts; their functional roles; and the relationships between them. Integrating these aspects in a coherent and interchangeable manner appears to be achievable, but the most appropriate format is as yet unclear.

- This entry looks at the origins of the Bliss Bibliographic Classification 2nd edition and the theory on which it is built. The reasons for the decision to revise the classification are examined, as are the influences on classification theory of the mid-twentieth century. The process of revision and construction of schedules using facet analysis is described. The use of BC2 is considered along with some recent development work on thesaural and digital formats.

- Abstract
- S.R. Ranganathan is credited with the introduction of the term "facet" in the field of knowledge organization towards the middle of the twentieth century. Facets have traditionally been used to organize document collections and to express complex subjects. In the digital world, they act as filters to facilitate navigation and improve retrieval. But the popularity of the term does not mean that a definitive characterization of the concept has been established. Indeed, several conceptualizations of the facet co-exist. This article provides an overview of formal and informal definitions found in the literature of knowledge organization, followed by a discussion of four common conceptualizations of the facet: process vs product, nature vs function, object vs subject and organization vs navigation.

- Abstract
- Disciplines are felt by many to be a constraint in classification, though they are a structuring principle of most bibliographic classification schemes. A non-disciplinary approach has been explored by the Classification Research Group, and research in this direction has been resumed recently by the Integrative Level Classification project. This paper focuses on the role and the definition of facets in non-disciplinary schemes. A generalized definition of facets is suggested with reference to predicate logic, allowing for having facets of phenomena as well as facets of disciplines. The general categories under which facets are often subsumed can be related ontologically to the evolutionary sequence of integrative levels. As a facet can be semantically connected with phenomena from any other part of a general scheme, its values can belong to three types, here called extra-defined foci (either special or general), and context-defined foci. Non-disciplinary freely faceted classification is being tested by applying it to little bibliographic samples stored in a MySQL database, and developing Web search interfaces to demonstrate possible uses of the described techniques.

- Several of the papers are clearly written as primers and neatly address the second agenda item: attracting others to the study and use of facet analysis. The most valuable papers are written in clear, approachable language. Vickery's paper (p. 145-160) is a clarion call for faceted classification and facet analysis. The heart of the paper is a primer for central concepts and techniques. Vickery explains the value of using faceted classification in document retrieval. Also provided are potential solutions to thorny interface and display issues with facets. Vickery looks to complementary themes in knowledge organization, such as thesauri and ontologies as potential areas for extending the facet concept. Broughton (p. 193-210) describes a rigorous approach to the application of facet analysis in the creation of a compatible thesaurus from the schedules of the 2nd edition of the Bliss Classification (BC2). This discussion of exemplary faceted thesauri, recent standards work, and difficulties encountered in the project will provide valuable guidance for future research in this area. Slavic (p. 257-271) provides a challenge to make faceted classification come 'alive' through promoting the use of machine-readable formats for use and exchange in applications such as Topic Maps and SKOS (Simple Knowledge Organization Systems), and as supported by the standard BS8723 (2005) Structured Vocabulary for Information Retrieval. She also urges designers of faceted classifications to get involved in standards work. Cheti and Paradisi (p. 223-241) outline a basic approach to converting an existing subject indexing tool, the Nuovo Soggetario, into a faceted thesaurus through the use of facet analysis. This discussion, well grounded in the canonical literature, may well serve as a primer for future efforts. Also useful for those who wish to construct faceted thesauri is the article by Tudhope and Binding (p. 211-222). This contains an outline of basic elements to be found in exemplar faceted thesauri, and a discussion of project FACET (Faceted Access to Cultural heritage Terminology) with algorithmically-based semantic query expansion in a dataset composed of items from the National Museum of Science and Industry indexed with AAT (Art and Architecture Thesaurus). This paper looks to the future hybridization of ontologies and facets through standards developments such as SKOS because of the "lightweight semantics" inherent in facets.
