SentimentAnalyzer on Amazon review dataset - Findings

[abhishalya]

This issue is a part of Google Code-in 2019 task. As a part of the task I'm reporting my findings on running the pre-trained SentimentAnalyzer with the Amazon review dataset as requested.

I found the accuracy of the model to be 51.71916007215394 percent.

Also, I found this issue #160 and for that I simply ignored all such instances where the error was being reported. I found out the difference is very low and hence can be neglected.

I've also uploaded the notebook file to the GCI website.
