- Abstract
- Discusses current information retrieval methods based on recall (R) and precision (P) for evaluating information retrieval and examines their suitability for evaluating the performance of hypermedia digital libraries. Proposes a new quantitative evaluation methodology, based on the structural analysis of hypermedia networks and the navigational and search state patterns of information seekers. Although the proposed methodology retains some of the characteristics of R and P evaluation, it could be more suitable than them for measuring the performance of information-seeking environments where information seekers can utilize arbitrary mixtures of browsing and query-based searching strategies
