ManajsAnalysis of Social Media Spring, 2011
Jump to navigationJump to search

Intention behind taking the course: Interest in social media, which is a rapidly growing phenomenon on web. Along with other things, i was particularly interested in modeling and analysis of the discussion between people in online forums, or as comments to blogs or news-stories. Such comments are pretty interesting in terms of their length and the kind of information they carry--while some are pretty small and loosely written, others are long and well-crafted ones. Want to do a project on similar lines analyzing this domain of social interaction. Research Interests: Language Technologies, Semantic Analysis, Discourse Analysis and Text modeling.

Project Proposal

Finding bias-groups in discussions on blogs

Team Members

Subhodeep Moitra ( Srivastava (

Data Set

Yano and Smith dataset of blogs and comments from 40 blog-sites focused on American politics [1]

Goal of the Project

We aim at modeling and estimating the bias groups among the users who make comments on blogs. For any blog, the users making comments either agree or disagree with the opinions of the author or of other users making comments. Also, these agreements and disagreements could be on various sub-topics discussed within a single blog. We aim at estimating which users are agreeing or disagreeing on what sub-topics of a given blog. We have gone through few papers which tackle different aspects of this problem separately. Hu et. al. [1] did extraction based summarization of sentences from blog-posts based on the content of the comments. Such an attempt is useful for us, so that we can relate the discussions in the comments with the sub-topics in the blog-posts. Another interesting work by Mishne and Glance [2] aims at detecting disputes in comments to web-blogs, which again relates to what we attempt to do. Another paper by Schuth et. al. [3] aims at finding the comments which relate to one thread of discussion. This is particularly useful in cases where the users cannot reply to other users’ comments explicitly. The techniques used in this paper could be useful in our case, to find out the likely discussion thread among all the posts on a certain blog.
