- 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
- Selection of search terms in an online search environment can be facilitated by the visual display of a knowledge map showing the various concepts and their links. This paper reports an a preliminary research aimed at designing a prototype knowledge map using DDC and its visual display. The prototype knowledge map created using the Protégé and TGViz freeware has been demonstrated, and further areas of research in this field are discussed.
- Content
- 1. Introduction Web search engines and digital libraries usually expect the users to use search terms that most accurately represent their information needs. Finding the most appropriate search terms to represent an information need is an age old problem in information retrieval. Keyword or phrase search may produce good search results as long as the search terms or phrase(s) match those used by the authors and have been chosen for indexing by the concerned information retrieval system. Since this does not always happen, a large number of false drops are produced by information retrieval systems. The retrieval results become worse in very large systems that deal with millions of records, such as the Web search engines and digital libraries. Vocabulary control tools are used to improve the performance of text retrieval systems. Thesauri, the most common type of vocabulary control tool used in information retrieval, appeared in the late fifties, designed for use with the emerging post-coordinate indexing systems of that time. They are used to exert terminology control in indexing, and to aid in searching by allowing the searcher to select appropriate search terms. A large volume of literature exists describing the design features, and experiments with the use, of thesauri in various types of information retrieval systems (see for example, Furnas et.al., 1987; Bates, 1986, 1998; Milstead, 1997, and Shiri et al., 2002).

- Abstract
- In order to enhance the use of Universal Decimal Classification (UDC) numbers in information retrieval, the authors have represented classification with multilingual thesaurus descriptors and implemented this solution in an automated way. The authors illustrate a solution implemented in a BiblioPhil library system. The standard formats used are UNIMARC for subject authority records (i.e. the UDC-based multilingual thesaurus) and MARC XML support for data transfer. The multilingual thesaurus was built according to existing standards, the constituent parts of the classification notations being used as the basis for search terms in the multilingual information retrieval. The verbal equivalents, descriptors and non-descriptors, are used to expand the number of concepts and are given in Romanian, English and French. This approach saves the time of the indexer and provides more user-friendly and easier access to the bibliographic information. The multilingual aspect of the thesaurus enhances information access for a greater number of online users

- 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.

- 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
- The paper analyses the importance of data presentation and modelling and its role in improving the management, use and exchange of analytico-synthetic classifications in automated systems. Inefficiencies, in this respect, hinder the automation of classification systems that offer the possibility of building compound index/search terms. The lack of machine readable data expressing the semantics and structure of a classification vocabulary has negative effects on information management and retrieval, thus restricting the potential of both automated systems and classifications themselves. The authors analysed the data representation structure of three general analytico-synthetic classification systems (BC2-Bliss Bibliographic Classification; BSO-Broad System of Ordering; UDC-Universal Decimal Classification) and put forward some core requirements for classification data representation

- 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
- 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 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
- The interfaculty centre of Bologna University began 2 years ago a project to 'translate' UDC codes into a user friendly thesaurus, with the object of creating an accurate, easy to use tool for online researches, especially those relating to periodical titles. The UDC numerical codes have been linked by a method based on synonyms to a series of corresponding verbal indices which express in natural language the concepts expressed by the codes. Thus researchers can retrieve information not only through UDC codes but also through their analogous verbal descriptors. Describes the progress of the UDC project so far, and some problems encountered

- 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

- Abstract
- Internet information retrieval is largely the preserve of search engines and the even more popular subject trees. Subject trees have adapted principles of conventional bibliographic classification for structuring hierarchic browsing interfaces, thus providing easily used pathways to their selected resources. This combination of browsing and selectivity is especially valuable to untrained users. For the forseeable future, it appears that subject trees will remain the Internet's only practicable use of classificatory methods for information retrieval

- 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
- 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
