Tomoko Uchida commented on LUCENE-10493:
----------------------------------------
I'm trying to factor out the core algorithm from Japanese/Korean Tokenizers
with the above modifications - it is still a very rough patch but anyhow, seems
to work...
I'd merge #793 and #795 after waiting for one or two days and then prepare the
main PR. The next step can't be small to show the full picture (creating a base
`Viterbi` class in analysis-common, moving the common logic to it, and
rewriting Japanese/Korean Tokenizers upon it), though, I will try to sort out
the interfaces for review.
> Can we unify the viterbi search logic in the tokenizers of kuromoji and nori?

> We now have common dictionary interfaces for kuromoji and nori
> ([LUCENE-10393]). A natural question would be: is it possible to unify the
> Japanese/Korean tokenizers?
> The core methods of the two tokenizers are `parse()` and `backtrace()` to
> calculate the minimum cost path by Viterbi search. I'd set the goal of this
> issue to factoring out them into a separate class (in analysis-common) that
> is shared between JapaneseTokenizer and KoreanTokenizer.
> The algorithm to solve the minimum cost path itself is of course
> language-agnostic, so I think it should be theoretically possible; the most
> difficult part here might be the N-best path calculation - which is supported
> only by JapaneseTokenizer and not by KoreanTokenizer.
