ABSTRACT	This paper claims that Belief Revision can be seen as a theoretical framework for document ranking in Extended Boolean Models. For a model of Information Retrieval based on propositional logic, we propose a similarity measure which is equivalent to a P-Norm case. Therefore it shares the PNorm good properties and behaviour. Besides, it is theoretically ensured that this measure follows the notion of proximity between the documents and the query. The logical model can naturally deal with incomplete descriptions of documents and the similarity values are also obtained for this case. 1 Introduction Logical approaches have been proposed to model Information Retrieval (IR) in a formal framework. Van Rijsbergen was the pioneer in thinking that logic could help in the retrieval of relevant documents [21]. Moreover, he proposed logic as a new theoretical framework for investigating IR. Given d, a logical representation of a document, and q, a logical representation of a query, retrieval is si...	user correction - Legacy Corrections
