There have been many studies for efficient implementation of regular expression matching. There have also been studies on parallel implementations of regular expression matching, but these implementations exploit parallelism only in executing a single query on multiple documents or in executing multiple queries on a single document. In this paper, we discuss a technique to parallelize a regular expression query itself. In other words, with this technique we can execute a regular expression query on a single document in parallel. We evaluate efficiency of regular expression matchings parallelized by the proposed method on the Hadoop; the Hadoop is an open-source implementation of the MapReduce framework that enables efficient processing of large-scale data.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会"}]},"item_2_rights_14":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"ここに掲載した著作物の利用に関する注意 本著作物の著作権は情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。"},{"subitem_rights":"Notice for the use of this material The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
