- Abstract
- Subject retrieval by Library of Congress (LC) Classification numbers is examined from the perspective of 5 user groups of on-line catalogues. Although, at present, librarians are the user group most likely to benefit from the LC classification advances in the capabilities of on-line catalogues. Research on the use of the LC classification schedules as a component of subject retrieval should continue.

- Abstract
- Results of a survey of North Carolina Libraries revealed that of 91 respondents, 29 had on-line catalogues. Of the libraries with on-line catalogues, 11 used the Dewey Decimal Classification (DDC). Survey findings indicate that the DDC has limited use in on-line searching today.

- Abstract
- Research leading to a detailed content analysis and profile of the Library of Congress Classification schedules. A description of the design, methodology, and preliminary findings of research in progress. Final results of the study are expected to aid the Library of Congress in the development of a MARC format for its classification schedules and in the conversion of the schedules into machine-readable form. LC's ultimate goal is the design of an integrated system which will permit on-line editing, maintenance, and control of the schedules, on-line classification and shelflisting procedures, the production of the schedules in two or more physical formats, and the use of LCC to enhance search capabilities in on-line catalogues.

- Abstract
- Librarians are often so eager to adopt new technologies and systems that they can lose sight of the realities that must be dealt with. Among factors that may delay use of Dewey Decimal Classification (DDC) for on-line catalogues retrieval are: limited use of DDC in libraries with operational on-line catalogues; limitations to the MARC bibliographic formats: lack of an authority structure for classification number for items catalogued. Factors that may delay development of effective classification retrieval mechanisms include unclear terminology and unreasonably high (or low) expectations.

- Abstract
- Classification numbers and shelf marks may be useful in online searching. Ways of using classification in online searching include: direct classification searching; use of classification as linking devices or pivots; and direct or indirect searching of classification schedules and indexes. Discusses each of these techniques, mainly in the context of library OPAC searching although they may be applied to other types of online retrieval systems. The use of classification numbers as pivots enabling online searchers to retrieve related references by means of automation searching of identical or related classification numbers is reviewed with reference to the OKAPI project; BLCMP project and the DDC online project

- Abstract
- There is every indication that classification systems which are international in their use, and free from the impact of national languages, will be given strong consideration as the choice for an information retrieval language in an automated environment. The aims of the Symposium were: to provide a forum for discussion of the problems and opportunities emerging from MARC records; to reconsider intellectual level as a significant determinant of information retrieval; and to explore the potential of the Dewey Decimal Classification and the Library of Congress Classification systems as information retrieval languages in an on-line environment.

- Abstract
- The study of faceted classification systems has primarily been directed towards application for precombined catalogues or bibliographies, not so much for use in post coordinated retrieval systems. Argues that faceted classification systems in some respects are superior to other techniques of on-line retrieval as far as facet and concept analysis is combined with an expressive notational system in order to guide a form of retrieval which will use Boolean operators (for combining the facets regardless of one special citation order) and truncation for retrieving hierarchically different sets of documents. This point of view is demonstrated by 2 examples. The 1st one uses a short classification system derived from B. Buchanan and the 2nd is built upon the classification system used by Library and Information Science Abstracts (LISA). Further discussion is concerned with some possible consequences which could be derived from a retrieval with PRECIS strings
"Online retrieval" conjures up a very different mental image now than in 1991, the year this article was written, and the year Tim Berners-Lee first revealed the new hypertext system he called the World Wide Web. Gödert shows that truncation and Boolean logic, combined with notation from a faceted classification system, will be a powerful way of searching for information. It undoubtedly is, but no system built now would require a user searching for material on "nervous systems of bone fish" to enter "Fdd$ and Leaa$". This is worth reading for someone interested in seeing how searching and facets can go together, but the web has made this article quite out of date.

- Abstract
- This response to the paper by Dr. Chan, while accepting the merits of call number searching in the theoretical sense, raises questions about its usefulness in typical library situations. Compares searching on-line with call numbers and the use of classified catalogues and shelflists. Asks who is expected to do call number searching. Considers the availability of indexes to the classification scheme, problems created by the provision of only 1 class number per document, and the use of multiple cutter numbers to express the subject of a document.

- Abstract
- This paper presents a study conducted at the University of Colorado at Boulder (CU-Boulder) to assess the extent to which its catalogers were using Classification Web (Class Web), the subscription-based, online cataloging documentation resource provided by the Library of Congress. In addition, this paper will explore assumptions made by management regarding CU-Boulder catalogers' use of the product, possible reasons for the lower-than-expected use, and recommendations for promoting a more efficient and cost-effective use of Class Web at other institutions similar to CU-Boulder.

- Abstract
- In 2001, a group of information architects involved in designing websites, and knowledge management specialists involved in creating access to corporate knowledge bases appeared to have re-discovered facet analysis and faceted classification. These groups have been instrumental in creating new and different ways of handling digital content of the Internet. Some of these practitioners explicitly use the forms and language of facet analysis and faceted classification, while others seem to do so implicitly. Following a brief overview of the work and discussions on facets and faceted classification in recent years, we focus on our observations about new information resources which seem more in line with the Fourth law of Library Science ("Save the time of the reader") than most library OPACs today. These new developments on the Internet point to a partial grasp of a disciplined approach to subject access. This is where Ranganathan and Neelameghan's approach needs to be reviewed for the new audience of information system designers. A report on the work undertaken by us forms a principal part of this paper.

- Abstract
- Creates an open, metadata aware system for distributed, collaborative WWW indexing. The system has 3 main components: a harvester (for collecting information), a database (for making the collection searchable), and a user interface (for making the information available). all components can be distributed across networked computers, thus supporting scalability. The system is metadata aware and thus allows searches on several fields including title, document author and URL. Nordic Web Index (NWI) is an application using this system to create a regional Nordic Web-indexing service. NWI is built using 5 collaborating service points within the Nordic countries. The NWI databases can be used to build additional services

- Abstract
- This is a report on how Doyle and others made a faceted classification scheme for content management systems and made it browsable on the web (see CMS Review in Example Web Sites, below). They discuss why they did it, how, their use of OPML and XFML, how they did research to find terms and categories, and they also include their taxonomy. It is interesting to see facets used in a business environment.

- Abstract
- Networked orientated standards for vocabulary publishing and exchange and proposals for terminological services and terminology registries will improve sharing and use of all knowledge organization systems in the networked information environment. This means that documentary classifications may also become more applicable for use outside their original domain of application. The paper summarises some characteristics common to documentary classifications and explains some terminological, functional and implementation aspects. The original purpose behind each classification scheme determines the functions that the vocabulary is designed to facilitate. These functions influence the structure, semantics and syntax, scheme coverage and format in which classification data are published and made available. The author suggests that attention should be paid to the differences between documentary classifications as these may determine their suitability for a certain purpose and may impose different requirements with respect to their use online. As we speak, many classifications are being created for knowledge organization and it may be important to promote expertise from the bibliographic domain with respect to building and using classification systems.

- The physical organisation of items on library shelves using any classification scheme is inevitable a compromise. The best efforts to achieve an arrangement that is helpful to users will be thwarted by the multifaceted nature of these items and the specific needs of the user and the library. Items on a particular subject will be scattered throughout the library building(s) across disciplines, by physical form, by frequency of use and whether and for how long they may be borrowed. Even thought he rich information content of multifaceted items may be represented in the notation, the items required by a user will be scattered across library shelves when the item is placed in a single relative location. This paper explores these issues uisng examples from a University Library classified using the DDC. The electronic context of the library OPAC can transcend the constraints imposed by the predominantly physical nature of library collections, yet the current use of classification schemes in on-line systems retains many of these limitations. Examples of such systems applying DDC on the WWW are discussed and compared with a system that seeks to use DDC in what is called view-based searching. The interface and the resulting browsing and searching capability of a view-based OPAC are described. Ways in which subject access to library collections can be improved and disciplinary scatter resolved by assigning multiple class number to items and exploiting the rich Dewey structure in a faceted form are discussed. It is suggested that the informative power of visual classificatory structures at the search interface will be beneficial to the broader learning experience of the user. The paper concludes that the application of classification schemes in electronic interfaces should not be bound by the the physical constraints that no longer apply in an electronic context but be exploited to provide a complete, flexible and individual interface as determined by the needs of each user

- Abstract
- This paper describes the background underlying and the methods to be used in an investigation of use of the gopher protocol for browsing and searching for information via the Internet. Networked information resources are notoriously difficult to find; gopher is one attempt to facilitate the processes of organization and retrieval in that environment. Our project will design classification schemes based on traditional library models (i.e. Dewey and Library of Congress) and compare use of these to use of an existing gopher. We describe the project, the research questions, literature on related issues, the construction of the classification schemes, and the experimental methodology used

- Abstract
- Modern fact databses contain abundant data classified through several classifications. Typically, users msut consult these classifications in separate manuals or files, thus making their effective use difficult. Contemporary database systems do little support deductive use of classifications. In this study we show how deductive data management techniques can be applied to the utilization of data value classifications. Computation of transitive class relationships is of primary importance here. We define a representation of classifications which supports transitive computation and present an operation-oriented deductive query language tailored for classification-based deductive information retrieval. The operations of this language are on the same abstraction level as relational algebra operations and can be integrated with these to form a powerful and flexible query language for deductive information retrieval. We define the integration of these operations and demonstrate the usefulness of the language in terms of several sample queries
