    Twitter removed “suspected users” from their platform during the week of Nov 1, 2018. This is potentially about 2.4 Million handles.

    Has the battle for General Elections 2019 shifted online?

    Social Media, today, is playing a very important role in the politics of almost every nation. In India, there has been a boom in social media political campaigns, which was more marked in the 2014 General Elections.  All major political parties used social media to promote their manifestos and interact in the public domain in a one-to-one manner. They analysed different views of the people, and worked on them. The Home Minister, in a seminar after the 2014 general elections, also said that “Through social media, the government is outlining its plan, its vision”. After assuming power, the NDA government has been using Twitter, Facebook and blogs to outline its…

    Collective Aspects of Privacy in the Twitter social network

    With an increased online participation on Social Media, privacy concerns have risen to unprecedented levels. It has become extremely important to allow individuals the full control of their private information. Popular mobile applications integrated with Online Social Networks (OSNs) allow them to access user’s private information like their contact lists. This might allow OSNs to create shadow profiles of non-users using the data of existing users. We test this hypothesis for the first time on Twitter and further evaluate the predictability of location and biographical vector of a user from the information given by a friend who has created a Twitter Profile before our user. Dataset To get an unbiased…

    Pages from a chapter called Precog

    Back in 2014, when I came to know about Dr. PK, he was associated with Backpack, FindAWay, IDEA and other cool things that were going around the campus. It was very intriguing because I did not know much about him except that and the courses that he took. Little later, I found out about Precog, the research group that he has at IIITD. For me, Precog was this intimidating elite group that I would never be able to be a part of. But oh! how wrong was I and so are you if you ever felt that. Trust me, I am an insider. 😛 Fast forward to 2015, I saw…

    What’s your MWI? : A social media based study of Mental Well-Being in college campuses

    College students’ mental health concerns are a persistent issue; psychological distress in the form of depression, anxiety and other mental health challenges among college students is a growing health concern. However, very few university students actually seek help related to mental illness. This arises due to various barriers like limited knowledge about available psychiatric services and social stigma. Further, there is dearth of accurate, continuous and multi-campus data on mental well-being which presents significant challenges to intervention and mitigation strategies in college campuses. Recent advances in HCI and social computing show that content shared on social media can enable accurate inference, tracking and understanding of the mental health concerns of…
