Descrição

This paper describes the participation of FEUP, from the University of Porto, in the TREC 2009 Blog Track. FEUP participated in the faceted blog distillation task with work focused on the use of temporal features available in the new TREC Blogs08 collection. The approach presented in this paper uses the temporal information available in most individual posts to amplify (or reduce) each post’s score. Blog scores, and subsequent ranks, are obtained by combining individual posts’ scores. While preparing the runs, no endeavors were made to identify a priori any temporal differences between the three distinct facets.
