Welcome to COIN Lab.

Welcome to the website of Computer and Information Networks (COIN) laboratory at University of Tehran. The mission of COIN lab is to perform innovative research in Social Networks and Media Analysis.

We are trying to analyze large-scale data gathered from online social media and networks sites, aiming to study user behaviors in such platforms. In the first area, we are mainly focused on the roles of structural properties of a network (i.e., the topology of a social network as an underlying network) in the behavior of dynamical processes over them. On the other hand, with rapid growth of Web 2.0 technologies and social media, nowadays we have a huge volume of opinionated data recorded in digital forms such as online reviews, forum discussions, comments on blogs and social networks. Then, in the second area, we are trying to process the content of a media (e.g., a tweet on Twitter) with NLP (natural language processing) methods for opinion mining and sentiment analysis.
