Robert Muir updated LUCENE-2522:
--------------------------------
Attachment: LUCENE-2522.patch
attached is an updated patch, its still a work in progress (needs some more
tests and benchmarking and some other things little fixes).
Theres a general pattern for these segmenters (this one, smartchinese, sen)
thats a little tricky, that is they want to really look at sentences to
determine how to segment.
So, I added a base class for this to make writing these segmenters easier, and
also to hopefully improve segmentation accuracy. (I would like to switch
smartchinese over to it) This class makes it easy to segment sentences with a
Sentence BreakIterator... in my opinion it doesnt matter how theoretically good
the word tokenization is for these things, if the sentence tokenizer is really
bad (I found this issue with both sen and smartchinese).
hope to get it committable soon
> add simple japanese tokenizer, based on tinysegmenter

> TinySegmenter (http://www.chasen.org/~taku/software/TinySegmenter/) is a tiny
> japanese segmenter.
> It was ported to java/lucene by Kohei TAKETA <[email protected]>,
> and is under friendly license terms (BSD, some files explicitly disclaim
> copyright to the source code, giving a blessing instead)
> Koji knows the author, and already contacted about incorporating into lucene:

> I've contacted Takeda-san who is the creater of Java version of
> TinySegmenter. He said he is happy if his program is part of Lucene.
> He is a co-author of my book about Solr published in Japan, BTW. ;-)
