Title

¬A theoretical study of recall and precision using a topological approach to information retrieval

Source

Information processing and management. 34(1998) nos.2/3, S.191-218

Year

1998

Abstract

Topologies for information retrieval systems are generated by certain subsets, called retrievals. Shows how recall and precision can be expressed using only retrievals. Investigates different types of retrieval systems: both threshold systems and close match systems and both optimal and non optimal retrieval. Highlights the relation with the hypergeometric and some non-standard distributions
