Microblogging has taken a considerable upturn in recent years, with the growth of microblogging websites like Twitter people have started to share more of their opinions about various pressing issues on such online social networks. A broader understanding of the domain in question is required to make an informed decision. With this motivation, our study focuses on finding overall sentiments of related topics with reference to a given topic. We propose an architecture that combines sentiment analysis and community detection to get an overall sentiment of related topics. We apply that model on the following topics: shopping, politics, covid19 and electric vehicles to understand emerging trends, issues and its possible marketing, business and political implications.

Sentiment analysis and community detection are two very active fields of research in computer science. They are both intimately linked to the modern phenomenon of social media, and can be very useful for extracting valuable information from a large corpus of social media posts. In this paper, we review the basic concepts of both fields and outline some of the algorithms and approaches that have been successfully applied. Finally, we take a look at the instances where both have been applied together.
