Title	Test Collections for Patent Retrieval and Patent Classification in the Fifth NTCIR Workshop
Authors	N. Kando, A. Fujii, M. Iwayama, N. Kando
Abstract	This paper describes the test collections produced for the Patent Retrieval Task in the Fifth NTCIR Workshop. We performed 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. For this purpose, we performed both document and passage retrieval tasks. We also performed the automatic patent classification task using the F-term classification system. The test collections will be available to the public for research purposes.
