> We have one scala stemmer in scalanlp%chalk
> https://github.com/scalanlp/chalk/tree/master/src/main/scala/chalk/text/analyze
> which can easily copied (as it is apache project) and is in scala too.
> I think this will be better alternative than lucene englishAnalyzer or
> opennlp.
> Note: we already use the scalanlp%breeze via the maven dependency so I think
> adding scalanlp%chalk dependency is also the options. But as you had said we
> can copy the code as it is small.
