Introduced are methods for computation of term-term association factors, indexing, assignment of term-document relevance values, and computation for recall and relevance. Recall and relevance are based on quantitative intenal system computations, and results are compared with user evaluations. (Author/MF)

Some problems encountered with the ERIC indexing system in efforts to retrieve information from the ERIC files are discussed. (4 references) (Author/NH)

Describes a series of studies conducted to determine how ERIC online searchers were using free and controlled vocabulary in their search statements and to understand relevance implications of the resultant differences. (SW)

Reviews some research on the use of library catalogs in the light of four functions (finding list, gathering, collocating, and evaluative); suggests that access points for each work be increased and that problems involved in entry choice be analyzed further. A list of references is included. (FM)

The bibliography is a compilation of annotated references on information sciences: information processing systems and techniques and is volume III in a four-volume set on information sciences. It is a revision to the unlimited references of the earlier bibliographies, AD-829 001 and AD-829 002, on the same subject. Volume III contains references…

Discusses features of online public access catalogs: (1) demonstration of relationships between records; (2) provision of entry vocabularies; (3) arrangement of multiple entries on the screen; (4) provision of access points; (5) display of single records; and (6) division of catalogs into separate files or indexes. User studies and other research…

This pilot study on the subject access problems of patrons of small to medium size libraries was designed to measure the extent to which users' vocabularies matched the search vocabulary of bibliographic records in the card catalog, and to enhance subject access by develooping a microcomputer system which integrated Library of Congress Subject…

Describes a study of library users' search strategies which focused on the extent of subject searching activity when using bibliographic tools and shelf browsing. The use of the results to evaluate the impact of a future online catalog on search behaviors is discussed. (23 references) (CLB)

Five issues must be considered if a more effective information and bibliographic delivery system is to be developed for Canadian education. (1) The size and characteristics of the reference group in Canadian education should be studied. With all its subgroups, this group may comprise as many as 200,000 people. (2) The number and types of documents…

This paper describes an experiment in the use of Dewey Decimal Classification in online catalogs to introduce classed approach to subject searching of library collections, enhance subject terminology indexed in online catalog, and provide possibilities for search strategies not possible through alphabetical approach of subject headings and/or…

Describes a study that examined the search behavior of remote users of the University of California MELVYL online public access catalog by analyzing the transaction logs. Highlights include the number of searches, databases searched, number of retrievals, constructing search commands, problems with search terms, and effectiveness of searches.…

This report presents the results of a study which explored how patron perceptions and demographics related to keyword/Boolean searching on Indiana State University's (ISU) Library User Information System (LUIS), the online public access catalog (OPAC). Two general theses guide the study: (1) whether the use or non-use of keyword searching on LUIS…

The effectiveness of current subject cataloging practices for assigning geographical headings to local historical records in meeting the requirements of an escalating number of genealogist-patrons was examined. The findings indicated that catalogers use two general approaches in determining subject headings for local historical collections in the…

Presents an Intelligent Negotiating Neural Network Design Model for solving the problem of poor information retrieval in subject searches of online catalogs. The purpose of the network, its architecture, and three different sessions of the user interface are described. Nineteen figures showing screens of the three sessions are appended. (Contains…

This study examined the use and perceived importance of the Internet among students and faculty in the Netherlands through questionnaires and focus-group interviews. Highlights include electronic journals, learning to use the Internet, search engines, needed library support, and problems with subject searching. A copy of the questionnaire is…
