چکیده
Jian-Yun Nie Département d'Informatique et Recherche opérationnelle, Université de Montréal C.P. 6128, succursale Centre-ville Montreal, Quebec H3C 3J7 Canada e-mail: [email protected] Abstract This paper describes a general approach to inferential information retrieval (IR). Different from the classical IR, in which the correspondence between a document and a query is estimated from a direct comparison of keywords included in them, an inferential approach also tries to infer indirect relevance relationship using a set of knowledge. A piece of knowledge is represented as an uncertain logical implication. It is converted from a thesaurus relation using relevance feedback. The experiments show that the approach is effective in practice.

Which Quantifiers Are Logical? a Combined Semantical and Inferential Criterion
The aim of logic is to characterize the forms of reasoning that lead invariably from true sentences to true sentences, independently of the subject matter; thus its concerns combine semantical and inferential notions in an essential way. Up to now most proposed characterizations of logicality of sentence generating operations have been given either in semantical or inferential terms. This paper...
متن کاملThe Terminological Image Retrieval Model
We present a model for image retrieval in which images are represented both at the form level, as sets of physical features of the representing objects, and at the content level, as sets of logical assertions about the represented entities as well as about facts of the subject matter that are deemed as relevant for retrieval. A uniform and powerful query language allows queries to be issued tha...
متن کاملRelevance as Deduction: A Logical View of Information Retrieval
The problem of Information Retrieval is, given a set of documents D and a query q, providing an algorithm for retrieving all documents in D relevant to q. However, retrieval should depend and be updated whenever the user is able to provide as an input a preferred set of relevant documents; this process is known as relevance feedback. Recent work in IR has been paying great attention to models w...
متن کاملRating the Impact of Logical Representations on Retrieval Performance
Logic provides a rich and uniform framework in which Information Retrieval can be modeled. The ability of logical approaches to give rise to more general Information Retrieval models is promising. However no much experimentation has been carried out about the real impact of logical representations on retrieval performance. This work is an attempt to fill this gap. Our work is based on a recent ...
