A support system for visually extracting discussion processes hidden in a mass of E-mails

This research aims to develop support methods for grasping discussion transition processes from e-mails. This research has proposed algorithms for extracting the streams of discussions and their progress states in utterance level. This paper mainly describes a support system for visually extracting the discussion processes. This paper also describes the experiments focusing on method replaceability in each extraction process together with the outlines of the algorithms and the prototype. Finally, the features of the methods are discussed based on the results.
