ALL FOR PAPERS Special Issue of Information Processing & Management on Patent Processing http://www.slis.tsukuba.ac.jp/~fujii/ipm_patent_cfp.html The processing of intellectual property documents, such as patents, is important in the industry, business, and law communities. Recently, the importance has also been recognized in scientific research communities, specifically, for information retrieval and natural language processing. In ACM SIGIR 2000 and ACL 2003, workshops on patent processing were held. The NTCIR Workshop have been organizing the Patent Retrieval Task since 2001. This special issue is intended to provide advanced research papers addressing patent processing. If you wish to submit a paper presented at a conference or workshop, we strongly encourage you to enhance the content, for example, by combining more than one conference paper or elaborating on technical details, deep analyses for experimental results, and discussions for related work. We invite research papers associated with, but not limited to, the following topics. - patent retrieval technology survey, invalidity search, cross-genre retrieval (e.g., associative retrieval between newspapers and patents), cross-language retrieval, integration of content-based and metadata-based retrieval, user modeling/interaction for processional patent searchers - patent classification categorization based on International Patent Classification and F-term, statistical approaches, machine learning techniques - natural language processing for patent processing text summarization, readability enhancement for claims, machine translation, natural language generation of claims, term extraction, thesaurus production, ontology construction - analysis data/text mining for patent database, automatic patent map generation - data engineering document structure models and markup languages for patent documents Important Dates: September 1, 2005: Submission due November 1, 2005: Notification to authors January 9, 2006: Submission due for revised version Special Issue Editors: Atsushi Fujii (University of Tsukuba, Japan) Makoto Iwayama (Tokyo Institute of Technology, Japan) Noriko Kando (National Institute of Informatics, Japan) Contact: Atsushi Fujii Graduate School of Library, Information and Media Studies University of Tsukuba fujii@slis.tsukuba.ac.jp
