Abstract:We introduce an efficient coding system for dynamic topic analysis (DTA), a computer-mediated discourse analysis technique that codes and visualizes topical development over time in online discussions. Our system provides three main functionalities: intuitive coding with a touch screen interface, automated inter-rater agreement computation, and visualization of the coding results. Using the system, we conducted a preliminary DTA of 28,131 user comments from the popular music distribution sites SoundCloud and Last.fm. The analysis shows that most SoundCloud and Last.FM comments are narrowly on-topic and prompt-focused, as compared to discussions in other social media that exhibit more topical elaboration.
