Abstract

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 (EFRS) was evaluated in comparison to a simulated traditional retrieval system (TRS) involving a set of predetermined empirical queries. Results indicate that the EFRS generally outperformed the TRS in terms of precision, search effort, and measures of user satisfaction. Possible advantages of the EFRS, as well as the necessity of establishing an efficient methos for extracting empirical facts, are discussed
