Reviews a selection of international collaborative efforts in the production of information services and attempts to characterize modes of cooperation. Methods and rationale for international information transfer and future program prospects are discussed. (JVP)

Reviews the goals and methods of research and development in documentation, stressing research which aims to improve the communication between the information user and source. Research is discussed within the context of the documentation system rather than by specific results. (JVP)

Discusses the prospects for fully automatic machine translation of good quality. Sections include history and background, operational and experimental machine translation systems of recent years, descriptions of interactive systems and machine-assisted translation, and a general survey of present problems and future possibilities.

Reports experiments with a term weighting model incorporating relevance information in which it is assumed that index terms are distributed dependently. It is argued that, if high recall searches are required, relevance feedback based on the modified dependence model may be superior to the Boolean search. (Author/VT)

A consideration of the development of on-line systems in terms of the computer changes that made on-line searching possible, and the use of these changes by information retrieval systems. (Author/KP)

Outlines a behavioral approach to information retrieval system design based on the derivation of a behavioral model of the information-seeking patterns of academic social scientists. The extent to which identified information-seeking characteristics are supported by existing systems is considered, and requirements for implementing these features…

Describes PLEXUS, an expert system for information retrieval related to gardening, designed at the University of London for use in public libraries. Focusing on the semantic problems encountered, methods used in artificial intelligence and information science to resolve them are discussed, including classification and facet analysis. (Author/LRW)
