Constructing a Japanese Basic Named Entity Corpus of Various Genres

要旨

This paper introduces a Japanese Named Entity (NE) corpus of various genres. We annotated 136 documents in the Balanced Corpus of Contemporary Written Japanese (BCCWJ) with the eight types of NE tags defined by Information Retrieval and Extraction Exercise. The NE corpus consists of six types of genres of documents such as blogs, magazines, white papers, and so on, and the corpus contains 2,464 NE tags in total. The corpus can be reproduced with BCCWJ corpus and the tagging information obtained from https://sites.google.com/ site/projectnextnlpne/en/ .
