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 implementation of a full-text image retrieval system at the Boeing Commercial Airplane Group. The conversion of card formats to a microcomputer-based system using HyperCard is described; the online system architecture is explained; and future plans are discussed, including conversion to digital images. (LRW)

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…

The impact of emerging information technologies on the information industry is discussed in four papers. Topics covered include electronic delivery of full text primary literature; a brief evaluation of new information processing technologies and software; networking technologies; and the use of gateway technologies to create new products and…

Discusses expected future developments in full text databases (FTDs) in three main areas: host-based menu-driven systems; menu and front end interfaces on gateway and mailbox services; and microcomputer or front end computer-based systems which already have good retrieval interactions and input output processing features.
