Implementing and Evaluating an Empirical Variable Retrieval System : The Entity-Relationship and Relational Approach
Sam-Gyun Oh · Journal of the Korean Society for Library and Information Science · 1998
This article investigates the potentialities of using empirical variables and their associated statistical relationships in document representation and retrieval. To this end, a newly devised empirical fact retrieval system was evaluated in comparison to a simulated traditional retrieval system involving a set of predetermined empirical queries. Results indicate that the EFRS generally outperformed the TRS in terms of the precision, search effort, and measures of user satisfaction.
