Abstract
This paper addresses the impact of structure on terms weighting function in the context of focused Information Retrieval (IR). Our model considers a certain kind of structural information: tags that represent logical structure (title, section, paragraph, etc.) and tags related to formatting (bold, italic, center, etc.). We take into account the tags influence by estimating the probability that a tag distinguishes relevant terms. This weight is integrated in the terms weighting function. Experiments on a large collection during INEX 2008 IR competition showed improvements for focused retrieval.
