The use of social media has become a part of life these days. There’s barely a person who is not involved in social media. With the growth of social media, people dependency on social media for news, information and mostly for entertainment has become a vital part. Social sites have become a place to spill emotions, thoughts, and frustrations of most of the peoples.
The growing trend of people’s involvement in social sites embarked us to develop a social networking site where the registered user can post their thoughts and feelings. The “User Activity Analysis Using Sentiment Analysis” is a system that is based on the collection of public opinion and analyzing the opinions using Bayesian Algorithm. Sentiment analysis technique is an effective means of discovering public opinions. Various companies often use online or paper-based surveys to collect customer comments. Due to the emergence of social networking sites and applications, people tend to express on the social site. Therefore, the paper-based approach is not an efficient approach. Only a very small group of people can be reached and there is no guarantee that their opinions in the survey are honest or not. Here social media comes into play. Facebook, Twitter, and all other social media sites are full of people’s opinions about products/services they use, comments about popular personalities, and much more. Hence mining opinions about various subject matters from social media is a much more innovative approach to the market.

The project is focused on the collection of posts done by a user in a certain period of time. The posts are then processed to obtain a certain result which eventually defines the sentiment of people or the field of interest. The purpose of developing the social site which collects the user activity is to identify the user’s sentiment so that we can treat the person accordingly. The system aims to identify the people’s sentiment which can further be deployed for the product advertisement, recommendation, crime investigation and various other purposes.
