Abstract

Myriad new information resources are available to contemporary library users. While print remains the foundation of most collections, libraries are also beginning to provide access to an array of bibliographic, numeric, and full-text databases. As more and more information is produced in electronic form and presented at computer workstations, the library catalog is being given an expanded role. The expanded catalog will play a crucial part in organizing information in electronic libraries, and in providing navigational assistance to library users. Like the traditional card catalog, the expanded catalog will not only lead to specific items or groups of sources, but also will provide connections to related materials. These connections will uses standard data elements to link the results of a search in one database with related material in another. For example, links will show local library holdings of sources in citation databases. Cornell University's Mann Library serves the College of Agriculture and Life Sciences, the College of Human Ecology, and the Division of Biological Sciences. As part of electronic library development, Mann staff have been analyzing issues involved in making it possible for Agricola and BIOSIS users to see, automatically, which of their retrieved citations are from sources available in the Cornell libraries. Samples of citations from Agricola and BIOSIS were drawn, and data elements present in these records were compared with bibliographic records of the library's holdings. In some cases, links would be provided by ISSNs. The study shows, however, that the presence of standard identifiers such as ISSN, USBN, or CODEN cannot be assumed, and other linking algorithms must be developed. This article presents study results, provides an overview of several linking systems, and identifies some of the difficulties caused by lack of standardization between different bibliographic databases. It is clear that the concept of an expanded catalog will require not only links between information resources but agreements among information professionals on standard data elements.

Abstract

Traditional subject cataloguing hampers subject retrieval in central catalogues, because of the lack of a common indexing and retrieval language in these catalogues. This study investigates the possibilities to use the various individual subject access systems, present in the catalogues, for subject access. A search procedure based on 'citation pearl growing' and 'user relevance feedback', which can be applied in a public access interface to central data bases, has been developed. From an experiment it can be concluded, that automated expert assistance, provided with a search strategy, will improve search response for unexperienced searchers. It reduces the number of zero-hits and increases the number of relevant items retrieved

Abstract

As librarians plan ahead to make subject enhancements available to online searchers in various possible file locations and formats, they may want to base their decisions on implications for online searching. This paper explores some of these implications with respect to unique and misleading terminology in tables of contents, Choice abstracts, and reviews from Computing reviews for thirty-six books on information and computer science chosen from the 1987 issues of Choice. It also discusses possible interacting functions in the search process served by these subject enhancements, assigned LCSH, and book title terminology

Abstract

Contents notes can improve online access to works containing essays, short stories, and significantly titles chapters. Few records in bibliographic utilities include contents notes. The OCLC PRISM service may provide an opportunity to cooperatively build a contents-enriched database. This paper discusses some issues related to the creation of enhanced records and their display in online cataloges. It also describes one library's efforts to add contents notes lically and to participate in an anticipated OCLC pilot project

Abstract

This article describes our efforts in supporting information retrieval from OCR degraded text. In particular, we report our approach to an automatic cataloging and searching contest for books in multiple languages. In this contest, 500 books in English, German, French, and Italian published during the 1770s to 1970s are scanned into images and OCRed to digital text. The goal is to use only automatic ways to extract information for sophisticated searching. We adopted the vector space retrieval model, an n-gram indexing method, and a special weighting scheme to tackle this problem. Although the performance by this approach is slightly inferior to the best approach, which is mainly based on regular expression match, one advantage of our approach is that it is less language dependent and less layout sensitive, thus is readily applicable to other languages and document collections. Problems of OCR text retrieval for some Asian languages are also discussed in this article, and solutions are suggested

Abstract

Describes the Intelligent Literature Search Assistant (ILSA) which demonstrates the possibilities of a fully automated cataloguing workbench in an object orientated environment. Although developed with OPAC users in mind, it can be very useful to cataloguers in aiding both classification and subject heading access. Also describes work done at the University of Strathclyde in the area of machine learning and knowledge based systems, the Structured Information Management: Processing and Retrieval project (SIMPR). Advocates the use of uncontrolled vocabulary headings in conjunction with systems like ILSA, a layered approach rather than direct first point access, in order to make subject cataloguing easier and more relevant and the subject catalogue more useful to others
