UJM at INEX 2007: Document Model Integrating XML Tags
Abstract
Different approaches have been used to represent textual documents, based on boolean model, vector space model or probabilistic models. In text min- ing as in information retrieval (IR), these models have shown good results about textual documents modeling. They nevertheless do not take into account docu- ments structure. In many applications however, documents are inherently struc- tured (e.g. XML documents). In this article1 , we propose an extended probabilistic representation of docu- ments in order to take into account a certain kind of structural information: logical tags that represent the different parts of the document and formatting tags used to emphasized text. Our approach includes a learning step that estimates the weight of each tag. This weight is related to the probability for a given tag to distinguish the relevant terms.
