I agree here with the level of effort needed to properly capitalize anything in a semantic fashion without some approximation mechanics. The only clear way to do capitalization in a deterministic fashion is simply to rely upon delimiters. I would think that admitting defeat (for commons) isn’t an unreasonable option, with the possibility of putting the bulk of the work in OpenNLP. I would think that would be a better venue for such an algorithm because of the mechanics of language determination being present there and not here. > Names will be a particular problem: ee cummings, D'Ath, O'Toole, MacDonald > > --------------------------------------------------------------------- > To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org > For additional commands, e-mail: dev-h...@commons.apache.org > --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
