Hi All, We cannot use existing NLP toolbox for our use case since it was implemented using Stanford NLP. Plus it cannot be used for loading custom trained models. We have already implemented most of the NLP parts using Apache OpenNLP. Therefore we are planning to write a custom adapter for NLP purpose. Please give your suggestions.
Thanks. Madhawa On Mon, Nov 3, 2014 at 12:05 PM, CD Athuraliya <chathur...@wso2.com> wrote: > Hi all, > > We are working on a road traffic extractor from Twitter feed.
