Unity Is Strength: Coupling Media for Thematic Segmentation

In this paper we present the preliminary results and the evaluation of a combined thematic segmentation of (a) meeting documents and (b) meeting speech transcript. Our approach is based on a clustering method applied on a 2D representation of the thematic alignment, and then the projection of the extracted clusters on each axis, corresponding to meeting documents and the speech transcript. Finally, our bi-modal thematic segmentation method is evaluated, in regards to a mono-modal segmentation method (TextTiling).
