Social Media : Detection the "buzz"

Over the part few years we have seen the power of Social Media in all aspect of our life, ranging from personal to business to politics. Social networking sites, like Facebook, Twitter and G+ are now household name. Social Media has changed the way netizen communicate with each other and how we get the news. However, it comes with a great price, ie data overload and with lots of "babbles". There is so much data and making sense out of the data is a major challenge facing the research community.

The talk will cover an interesting way to detect "hot topics" in new media using wavelet analysis. Words with similar frequency patterns are clustered together to form events with a modularity-based graph partitioning technique. A prototype system was build recently for the Singapore general election where we measure the political parties sentiment and hot topics. The results have been very promising and has attracted much attention.
