Patent Retrieval Experiments in the Context of the CLEF IP Track 2009

At CLEF 2009 the University of Hildesheim focused on the main task of the Intellectual Property Track which aims at finding prior art for a specified patent [cf. Information Retrieval Facility 2009]. The experiments of the University of Hildesheim concentrated on a baseline approach including stopword elimination, stemming and simple term queries. Furthermore only title and claim were included into the index as especially the second one is considered to be the most important patent part during a prior art search [cf. Graf/Azzopardi 2008: 64].
