> I've been playing with the idea of changing the Kuromoji viterbi
> search to be 2 passes (intersect, backtrace) instead of 4 passes
> (break into sentences, intersect, score, backtrace)... this is very
> much a work in progress, so I'm just getting my current state up.
> It's got tons of nocommits, doesn't properly handle the user dict nor
> extended modes yet, etc.
> One thing I'm playing with is to add a double backtrace for the long
> compound tokens, ie, instead of penalizing these tokens so that
> shorter tokens are picked, leave the scores unchanged but on backtrace
> take that penalty and use it as a threshold for a 2nd best
> segmentation...
