Describes information architecture as a high-level map of the information requirements of a corporation that can be used as a base for developing effective information systems. Methodologies for development, problems involved, and benefits are discussed, several examples are cited, and prescriptive recommendations are given. (Author/LRW)

Describes methods for effecting the partition of information systems consisting of many components and interconnections into subsystems which are later made to interface with one another achieving an overall system. Clustering algorithms for the specific case of information systems are obtained and exemplified. Twenty-seven references are…

Describes interorganizational information systems and the necessity for cooperation. Topics discussed include managerial considerations, including objectives, benefits, and resources; considerations in systems development, including telecommunications skills; considerations for users of information systems, including user needs; and considerations…

Discusses the inability of the standard Boolean logic model of information retrieval to deal effectively with the inherent fallibility of retrieval decisions. Recent advances in information retrieval research are reviewed, and their practical potential for overcoming the deficiencies of the Boolean model is examined. (45 references) (Author/CLB)

Argues that the best strategy for building integrated, personalized information systems consists of linguistically oriented knowledge and inference, rather than artificial intelligence techniques. The discussion addresses difficulties in the evaluation of such systems and strategies for devising performance studies. (five references) (CLB)

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)

Based on the literature and interviews with personnel in the United Kingdom, this article identifies possible roles for information professionals in the design and development of expert systems. The need for training in expert systems, communications with computer scientists, and improved recognition of the information science profession are…

Describes two experiments that were conducted at the University of Illinois to determine how cognitive abilities of users of information retrieval systems and specific design features combine to create system usability. Logical reasoning and perceptual speed are examined, and reliability and validity are discussed. (Contains 12 references.) (LRW)

Discusses what designers do, information they need, and how they might be aided, as background information for developing useful computer-aided decision systems to enhance designers' productivity. It is concluded that effectiveness of computer-assisted design systems depends on the value of the information and the flexibility of the support they…
