- Abstract
- The evaluation of an implication by imaging is a logical technique developed in the framework of modal logic. Its interpretation in the context of a 'possible worlds' semantics is very appealing for information retrieval. In 19889, Van Rijsbergen suggested its use for solving 1 of the fundamental problems of logical models of information retrieval: the evaluation of the logical implication that a document is relevant to a query if it implies the query. Since then, others have tried to follow that suggestion proposing models and applications, though without much success. Most of these approaches had as their basic assunption the consideration that ' document is a possible world'. Proposes instead an approach based on a completely different assumption: ' a term is a possible world'. This approach enables the exploitation of term-term relationships which are estimated using an information theoretic measure
