Peer reviewedBuckland, Michael K.; Florian, Doris – Journal of the American Society for Information Science, 1991
Examines the relationship between users' expertise, task complexity of information system use, and artificial intelligence to provide the basis for a conceptual framework for considering the role that artificial intelligence might play in information systems. Cognitive and conceptual models are discussed, and cost effectiveness is considered. (27…

Peer reviewedCouvreur, T. R.; And Others – Journal of the American Society for Information Science, 1994
Discusses the results of modeling the performance of searching large text databases via various parallel hardware architectures and search algorithms. The performance under load and the cost of each configuration are compared, and a common search workload used in the modeling is described. (Contains 26 references.) (LRW)
