An Application Of Plausible Reasoning To Information Retrieval, Farhad Oroumchian, Robert Oddy Dec 1995

An Application Of Plausible Reasoning To Information Retrieval, Farhad Oroumchian, Robert Oddy

Robert Oddy

This work explores the use of plausible inferences as a means of retrieving relevant documents. Collins and Michalski’s theory of plausible reasoning has been modified to accommodate information retrieval. Methods are proposed to represent document contents by logical terms and statements, and queries by incomplete logical statements. Extensions to plausible inferences are discussed. Two versions of the extended plausible reasoning system were implemented, one using dominance weights (described in the paper) and the other using tf. Idf (Term Frequency Inverse Document Frequency) weights. Experiments were conducted using the titles and abstracts of the CACM collection and it was found ...
