Subject [jira] [Commented] (LUCENE-3730) Improved Kuromoji search mode segmentation/decompounding
Date Wed, 01 Feb 2012 10:12:59 GMT


Christian Moen commented on LUCENE-3730:

Patch looks good to me... so the basics are we apply a different penalty based on
whether the text is kanji or not, rather than just a single penalty of 10000 (and some parameter
tuning) ?

Thanks a lot, Robert.  That's correct.

I agree completely regarding other dictionary support.

> Kuromoji has a segmentation mode for search that uses a heuristic to promote additional
segmentation of long candidate tokens to get a decompounding effect.  This heuristic has been
improved.  Patch is coming up.
