- Abstract
- This paper discusses two inter-related themes: the retrieval potential of faceted thesauri and XML representations of fundamental facets. Initial findings are discussed from the ongoing 'FACET' project, in collaboration with the National Museum of Science and Industry. The work discussed seeks to take advantage of the structure afforded by faceted systems for multi-term queries and flexible matching, focusing in this paper an the Art and Architecture Thesaurus. A multi-term matching function yields ranked results with partial matches via semantic term expansion, based an a measure of distance over the semantic index space formed by thesaurus relationships. Our intention is to drive the system from general representations and a common query structure and interface. To this end, we are developing an XML representation based an work by the Classification Research Group an fundamental facets or categories. The XML representation maps categories to particular thesauri and hierarchies. The system interface, which is configured by the mapping, incorporates a thesaurus browser with navigation history together with a term search facility and drag and drop query builder.

- Abstract
- Subject based classification is an important part of information retrieval, and has a long history in libraries, where a subject taxonomy was used to determine the location of books on the shelves. We have been studying the notion of subject itself, in order to determine a formal ontology of subject for a large scale digital library card catalog system. Deep analysis reveals a lot of ambiguity regarding the usage of subjects in existing systems and terminology, and we attempt to formalize these notions into a single framework for representing it.

- PARAMESWARAN (Classification and Indexing: Impact of Classification Theory an PRECIS) reviews the PRECIS system and finds that "it Gould not escape from the impact of the theory of classification" (p. 131). The author further argues that the purpose of classification and subject indexing is the same and that both approaches depends an syntax. This leads to the conclusion that "there is an absolute syntax as the Indian theory of classification points out" (p. 131). SATYAPAL and SANJIVINI SATYAPAL (Classifying Documents According to Postulational Approach: 1. SA TSAN- A Computer Based Learning Package) and SATYAPAL and SANJIVINI SATYAPAL (Classifying Documents According to Postulational Approach: 2. Semi-Automatic Synthesis of CC Numbers) present an application to automate classification using a facet classification system, in this Gase, the Colon Classification system. GAIKAIWARI (An Interactive Application for Faceted Classification Systems) presents an application, called SRR, for managing and using a faceted classification scheme in a digital environment. IYER (Use of Instructional Technology to Support Traditional Classroom Learning: A Case Study) describes a course an "Information and Knowledge Organization" that she teaches at the University at Albany (SUNY). The course is a conceptual course that introduces the student to various aspects of knowledge organization. GOPINATH (Universal Classification: How can it be used?) lists fifteen uses of universal classifications and discusses the entities of a number of disciplines. GOPINATH (Knowledge Classification: The Theory of Classification) briefly reviews the foundations for research in automatic classification, summarizes the history of classification, and places Ranganathan's thought in the history of classification.

- Abstract
- A team at the University of Michigan School of Information designed, implemented and is evaluating a WWW-based experimental system which uses classification to facilitate browsing of art images. The research team built a database of approximately 3.000 digitized images from Art History to determine if classification can be used for retrieving images from a digital database in a networked environment. A key premise in this research is that browsing can serve an important role in retrieving image information. The system was evaluated in controlled tests and through a questionnaire available to WWW users

- Abstract
- Three pre-web articles about using hypertext for knowledge representation. Duncan discusses how to use graphical, hypertext displays (she used Xerox PARC's NoteCards on a Xerox 1186 workstation) along with concept maps and facet analysis, a combination that would now be done with topic maps. The screen shots of her graphical displays are quite interesting. Her interest in facets is in how to use them to show things to different people in different ways, for example, so that experts can enter knowledge into a system in one way while novices can see it in another. Duncan found that facet labels (e.g. Process and Product) prompted the expert to think of related concepts when inputting data, and made navigation easier for users. Facets can be joined together, e.g. "Agents (causing) Process," leading to a "reasoning system." She is especially interested in how to show relstionships between two things: e.g., A causes B, A uses B, A occurs in B. This is an important question in facet theory, but probably not worth worrying about in a small online classification where the relations are fixed and obvious. These articles may be difficult to find, in which case the reader can find a nice sumary in the next article, by Ellis and Vasconcelos (2000). Anyone interested in tracing the history of facets and hypertext will, however, want to see the originals.

- Abstract
- The paper gives a short overview of the history of use of UDC in Internet subject gateways (SGs) with an English interface, from 1993 to 2006. There were in total, nine quality controlled SGs that were functional for shorter or longer periods of time. Their typology and functionality is described. Quality SGs have evolved and the role of classification has changed accordingly from supporting subject organization on the interface and automatic categorization of resources, towards supporting a semantic linking, control and vocabulary mapping between different indexing systems in subject hubs and federated SGs. In this period, many SGs ceased to exist and little information remains available regarding their status. SGs currently using UDC, for some part of their resource organization, do not use a UDC subject hierarchy at the interface and its role in resource indexing has become more difficult to observe. Since 2000, UDC has become more prevalent in East European SGs, portals and hubs, which are outside the scope of this research. This paper is an attempt to provide a record on this particular application of UDC and to offer some consideration of the changes in requirements when it comes to the use of library classification in resource discovery.

- Abstract
- Broughton is one of the key people working on the second edition of the Bliss Bibliographic Classification (BC2). Her article has a brief, informative history of facets, then discusses semantic vs. syntactic relationships, standard facets used by Ranganathan and the Classification Research Group, facet analysis and citation order, and how to build subject indexes out of faceted classifications, all with occasional reference to digital environments and hypertext, but never with any specifics. It concludes by saying of faceted classification that the "capacity which it has to create highly sophisticated structures for the accommodation of complex objects suggests that it is worth investigation as an organizational tool for digital materials, and that the results of such investigation would be knowledge structures of unparalleled utility and elegance." How to build them is left to the reader, but this article provides an excellent starting point. It includes an example that shows how general concepts can be applied to a small set of documents and subjects, and how terms can be adapted to suit the material and users

- Abstract
- The universal classification schemes developed in the 19th century are a direct response to the social changes of that era. However, the increasing use of automation in libraries has highlighted the need fir greater precision in hierarchical structures. A thesaurus of used and related headings can be employed to show the spatial relationship of semantic terms. The resulting search profile can be further enhanced by the addition of citation weighting. To assist users to define searches more accurately libraries using large general classification schemes should consider adding supplementary classification data to records

- Abstract
- This paper aims to explore the changes in the role of classification and the opportunities presented for classification in the twenty-first century, especially in respect to the development of information technology. The issues arose as part of the EC funded MIRACLE project that represents the foundation for a virtual music library to serve visually impaired people. The MIRACLE partners chose the UDC as the common classification for the converging music catalogues. This paper investigates the nature of adaptation required by each participating library and the way in which the classification is used as a searching tool. Further developments in the use of IT-assisted classification are proposed

- Abstract
- We live in an information age that requires us, more than ever, to represent, access, and use information. Over the last several decades, we have developed a modern science and technology for information retrieval, relentlessly pursuing the vision of a "memex" that Vannevar Bush proposed in his seminal article, "As We May Think." Faceted search plays a key role in this program. Faceted search addresses weaknesses of conventional search approaches and has emerged as a foundation for interactive information retrieval. User studies demonstrate that faceted search provides more effective information-seeking support to users than best-first search. Indeed, faceted search has become increasingly prevalent in online information access systems, particularly for e-commerce and site search. In this lecture, we explore the history, theory, and practice of faceted search. Although we cannot hope to be exhaustive, our aim is to provide sufficient depth and breadth to offer a useful resource to both researchers and practitioners. Because faceted search is an area of interest to computer scientists, information scientists, interface designers, and usability researchers, we do not assume that the reader is a specialist in any of these fields. Rather, we offer a self-contained treatment of the topic, with an extensive bibliography for those who would like to pursue particular aspects in more depth.
