ABSTRACT
Splitting a meeting into segments such that each segment contains discussions on exactly one agenda item is useful for tasks such as retrieval and summarization of agenda item discussions. However, accurate topic segmentation of meetings is a difficult task. In this paper, we investigate the idea of acquiring implicit supervision from human meeting participants to solve the segmentation problem. Specifically we have implemented and tested a note taking interface that gives value to users by helping them organize and retrieve their notes easily, but that also extracts a segmentation of the meeting based on note taking behavior. We show that the segmentation so obtained achieves a Pk value of 0.212 which improves upon an unsupervised baseline by 45% relative, and compares favorably with a current state-of-the-art algorithm. Most importantly, we achieve this performance without any features or algorithms in the classic sense.

Participants' personal note-taking in meetings and its value for automatic meeting summarisation
This paper reports the results of novel quantitative research on multiple people's personal note-taking in meetings with the long-term aim of aiding the creation of innovative meeting understanding applications. We present three experiments using a ...
Recurring Meetings: An Experiential Account of Repeating Meetings in a Large Organization
Meetings are often seen solely as a site of collective work. However, as McGrath has noted, groups are concerned with much more than collective work. In this study we examine how individuals experience meetings, and ask what they do, why they do it, and ...
