Hey Alberto,
we started indexing for Czech using [2] but did not finish it because of the
missing stemmer. At the moment we only use snowball stemmers via Lucene but we
would be more than happy for contributions.
For [2], Stemmers need to implement org.dbpedia.spotlight.db.model.Stemmer
To make it general enough, you could add a companion object Stemmer, e.g.
> object Stemmer {
>
> def forLanguage(lang: String): Stemmer = {
> if (lang equals "cs")
> your stemmer
> else
> default snowball stemmer
> }
>
> }

Stemmer.forLanguage would have to be added to
org.dbpedia.spotlight.db.CreateSpotlightModel and
org.dbpedia.spotlight.db.SpotlightModel as well as to the pignlproc scripts
that do the counting in pignlproc.index.GetCounts*
In any case, using [2] and [1] should be the easiest method and give the best
results.
