@Lalith Thanks, Please use the Opinion Mining feature of Sentiment Analysis, starting in version 3.1. Also known as Aspect-based Sentiment Analysis in Natural Language Processing (NLP), this feature provides more granular information about the opinions related to attributes of products or services in text.

To get Opinion Mining in your results, you must include the opinionMining=true flag in a request for sentiment analysis.
Here Sentiment Analysis might only report a positive sentiment in this case.
