need to identify the sentiments of those tweets. A model must be constructed where the sentiments
are scored, for each product individually and then they are compared with, diagrammatically,
portraying users’ feedback from the producers stand point.
There are many websites that offer a comparison between various products or services based on
certain features of the article such as its predominant traits, price, and its welcome in the market and
so on. However not many provide a juxtaposing of commodities with user review as the focal point.
Those few that do work with Naïve Bayes Machine Learning Algorithms, that poses a disadvantage
as it mandatorily assumes that the features, in our project, words, are independent of each other.
This is a comparatively inefficient method of performing Sentiment Analysis on bulk text, for
official purposes, since sentences will not give the meaning they are supposed to convey, if each
word is considered a separate entity. Maximum Entropy Classifier overcomes this draw back by
limiting the assumptions it makes of the input data feed, which is what we use in the proposed
