Title: Kuromoji Codebase Intellectual Property (IP) Clearance Status
The project was started in 2010 since we couldn‘t find any high-quality, actively maintained and easy-to-use Java-based Japanese morphological analyzers, and these become many of our design goals for Kuromoji. Kuromoji also has a segmentation mode that is particularly useful for search, which we hope will interest Apache Lucene and Solr users. Compound-nouns, such as 関西国際空港 (Kansai International Airport) and 日本経済新聞 (Nikkei Newspaper), are segmented as one token with most analyzers. As a result, a search for 空港 (airport) or 新聞 (newspaper) will not give you a for in these words. Kuromoji can segment these words into 関西 国際 空港 and 日本 経済 新聞, which is generally what you would want for search and you’ll get a hit. The target was to make sure the technology has a license that makes it compatible with other Apache Software Foundation software to maximize its usefulness. Kuromoji has an Apache License 2.0 and all code is currently owned by Atilika Inc. The software has been developed by Masaru Hasegawa and Christian Moen.

Generally, the result of checking off these items will be a Software Grant, CLA, and Corporate CLA for ASF licensed code, which must have no dependencies upon items whose licenses that are incompatible with the Apache License.
