documents semi-structur´es

Abstract : Structural information contained in semi-structured documents can be used to focus on relevant information. The aim of Information Retrieval System is then to retrieve relevant information units instead of whole documents. We propose here the XFIRM model (XML Flexible Information Retrieval model), which is based on: (i) a generic data representation model, allowing the modelling of documents having heterogeneous structures; (ii) a flexible query language that allows the expression of users needs according to many precision degrees, by expressing (or not) conditions on the documents structure; (iii) a retrieval model based on a relevance propagation method, which aims at finding the most exhaustive and specific information units answering the query. The interest of our propositions has been shown thanks to the prototype we developed
