SMU Professor of Information Systems and Living Analytics Research Centre Director Lim Ee Peng, who specialised in databases during his PhD study, now focuses on analysing social media to yield valuable insights. However, before social media data can be used, there has to be a way to make sense of what is meaningful amidst the noise. Recognising this, Prof Lim has worked on developing ways to make use of social media data to identify interesting events that happen in the real world. Apart from event detection, he has also worked on identifying influential people within the Twitter network. As befitting a social media researcher, Prof Lim has done much of his research collaboratively. In particular, he credits the contributions of his colleagues at the Living Analytics Research Centre where he is the co-director.
