Thanks, Bruno and Matthew. I saw that tutorial before and Lingpipe requires a license while we are looking at open source solutions. We are not clear yet on how to use Solr to do sentiment analysis. Does a NLP or learning tool have to be used to accomplish this task? If a tool is needed, how it can be integrated with Solr? Then, what are the steps? By using classification? We are new to sentiment analysis and any suggestion is welcomed.
