Title

¬A searching procedure for information retrieval

Abstract

A search procedure for an information retrieval system is developed whereby the answer to a question is obtained by maximizing an evaluation function of the system's output in terms of the probility of relevance. Necessary and sufficient conditions are given for a set to be an answer to a query. A partition of the file is made in such way that all documents belonging to the answer are members of the same class. Hence the answer can be generated by one relevant document. In this manner a search of the total file is avoided
