The system takes as input a transcribed dialogue, and outputs topic change information for that dialogue. This information is in the form of a machine-readable (XML) file, a human-readable (HTML) transcript of the dialogue with topic changes marked, and a graph showing the continuous topic-cohesion metric for the dialogue, superimposed with marks indicating the locations of the detected topic breaks. Additionally, the system accepts human-marked topic changes, plotting them alongside its own detected changes: This allows all experiments to be evaluated easily for precision and recall against human judgement, which is the primary method of evaluation.3.1
