This paper 1 addresses the impact of structure on terms weighting function in the context of focused Information Retrieval (IR).  ...  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.  ...  Following [6] , we take advantage of the non linearity of BM25 by pre-impacting the tags weights at the term frequency level.  ...
