Title
Subject and citation indexing : pt.2: the optimal, cluster-based retrieval performance of composite representations
Source
Journal of the American Society for Information Science. 42(1991) no.9, S.676-684
Year
1991
Abstract
Fortsetzung von pt.1: experimental retrieval results are presented as a function of the exhaustivity and similarity of the composite representations and reveal consistent patterns from which optimal performance levels can be identified. The optimal performance values provide an assessment of the absolute capacity of each composite representation to associate documents relevant to different queries in single-link hierarchies. The effectiveness of the exhaustive representation composed of references and citations is materially superior to the effectiveness of exhaustive composite representations that include subject descriptions
