Abstract: Due to the Internet revolution, human conversational data–in written forms–are accumulating at a phenomenal rate, as more and more people engage in email exchanges, blogging, texting and other social media activities. In this talk, we will present automatic methods for analyzing conversational text and for visualizing the extracted information. Our focus will be on novel techniques to detect and visualize the topics and opinions covered in the conversation. In our work, we compare graph-based methods and probabilistic graphical models for mining information; and we apply a human centered design approach for visualizing the extracted info.
