The first of two papers discusses natural language searching as a user performance enhancement tool, focusing on artificial intelligence applications for information retrieval and problems with natural language processing. The second presents a conceptual framework for further development and future design of front ends to online bibliographic…

Argues that users' needs should play a more prominent role in the design or choice of an online catalog in a specific library, and outlines requirements which enhance ease of use. Areas discussed include operational control, search formulation control, access points, output control, user assistance, and hardware requirements. (nine references)…

Discusses the probabilistic nature of information retrieval, and describes a front end system designed to permit searchers to attach probabilistically interpreted weights to query terms, which could be adapted for conventional information retrieval systems without requiring radical changes in current indexing procedures. (37 references) (CLB)

Describes the development and evaluation of a CD-ROM local area network that allows multiple users to access the same CD-ROM disk simultaneously. The discussion covers the planning process, administrative issues, reactions of users and staff, and future issues to be considered in expanding CD-ROM access. (CLB)

Provides an overview of methods for improving the effectiveness of Boolean retrieval systems, including document clustering, relevance feedback, weighted term searching, ranked output, and fuzzy set theory. The discussion of experimental studies with the SMART and SIRE systems focuses on the implementation and results of these methods. (69…

This paper reviews the services provided by the ERIC system and suggests ways to broaden its scope through coordination with other existing education databases. The first of four major sections chronicles the evolution of ERIC and explains why it has not been able to exercise true bibliographic control over the literature of education. The second…
