Hi, Do you have the Sentiment dictionaries available in the launcher? For English the
<groupId>org.apache.stanbol</groupId> <artifactId>org.apache.stanbol.data.sentiment.sentiwordnet</artifactId> Bundle. Without a dictionary you will not get any results. So this could be the reason for the missing sentiment value. The chain looks fine. However you should not use two chunker so I recommend to remove the pos-chunker and keep the opennlp one. best Rupert On Wed, Mar 18, 2015 at 8:11 AM, <zahoorahmed.k...@cognizant.com> wrote: > Hi, > > I am trying to do a sentiment analysis for the sample input “this is not a > good product”.
