Peer reviewedBryson, Noel; And Others – Information Processing and Management, 1994
Presents a microcomputer-based qualitative discriminant process (QDP) for scoring and ranking in group support systems that is relevant to group decision-making situations that involve the evaluation of alternatives. Scoring and ranking techniques are described, and a case illustration using the QDP is discussed. (Contains 50 references.) (LRW)

Peer reviewedAigrain, Philippe; Longueville, Veronique – Journal of the American Society for Information Science, 1994
Describes an evaluation model for expansion systems in information retrieval, i.e., systems expanding a user selection of documents to provide the user with a larger set of documents sharing the same or related characteristics. Highlights include a test protocol and evaluation measures for the efficiency of expansion systems. (Contains 29…
