  1. INTRODUCTION

    The field of data analysis implies dissecting data in manners that uncover connections, designs, patterns found inside it. It basically gives us the result to what in particular level we can believe about appropriate responses we are getting by contrasting our data with others to find out needed result from the information. Basically there are two kind of data qualitative data that alludes to the information which is gathered or can be converted into numbers that can be represented numerically. And other one is qualitative data that is gathered in a format as it is descriptive, sentiment, quotes, translations, and so on. The famous and most basic tool for data analysis is MS Excel in which data can be arranged in the form to be in ascending and descending order, channel the information that meet specific models, display charts, perform conditional formatting on cells, get required information out from an enormous and itemized data collection utilizing pivot tables, formatting of tables to dissect our information rapidly and effectively. In this research work, an Add-in of MS Excel named Microsoft Azure Machine Learning that is basically used to do sentiment analysis was used. Many other tools like Analysis ToolPak which is an include program that gives solution for data analysis to do analysis of monetary, factual and designing engineering data analysis. Text data contains sentiment and feelings.

    Sentiments are elements, occasions and their properties likewise called as target articulations. Conclusions depict an individual's sentiments, opinions, evaluation's towards elements, occasions and their properties.

    Regardless of whether a particular decision is made or yet to be made is coordinating with the sentiments of the others to stay away from self-misfortune. One reason for the absence of sentiments is the way that there was minimal stubborn message accessible before the Internet.
