The patent retrieval task in the fourth NTCIR workshop
This paper describes the Patent Retrieval Task in the Fourth NTCIR Workshop, and the test collections produced in this task. We perform the invalidity search task, in which each participant group searches a patent collection for the patents that can invalidate the demand in an existing claim. We also perform the automatic patent map generation task, in which the patents associated with a specific topic are organized in a multi-dimensional matrix. Categories and Subject Descriptors H.3.3 [Information Search and Retrieval]: Search process; H.3.4 [Systems and Software]: Performance evaluation; H.3.5 [Online Information Services]: Data sharing General Terms Measurement, Performance, Experimentation Keywords test collections, associative patent retrieval, passage retrieval, patent maps
