We introduce a browser evaluation test (BET), and describe a trial run application of the test. BET is a method for assessing meeting browser performance using the number of <i>observations of interest</i> found in the minimum amount of time as the evaluation metric, where observations of interest are statements about a meeting collected by independent(More)
Presumably man's spirit should be elevated if he can better review his shady past and analyze more completely and objectively his present problems. He has built a civilization so complex that he needs to mechanize his record more fully if he is to push his experiment to its logical conclusion and not merely become bogged down part way there by overtaxing(More)
As the amount of multimodal meetings data being recorded increases, so does the need for sophisticated mechanisms for accessing this data. This process is complicated by the different informational needs of users, as well as the range of data collected from meetings. This paper examines the current state of the art in meeting browsers. We examine both(More)
Although speech is a potentially rich information source, a major barrier to exploiting speech archives is the lack of useful tools for efficiently accessing lengthy speech recordings. This paper develops and evaluates techniques for temporal compression - reducing the time people take to listen to a recording while still extracting critical information. We(More)
Users find it hard to delete unimportant personal information which often results in cluttered workspaces. We present a full design cycle for GrayArea, a novel interface that allows users to demote unimportant files by dragging them to a gray area at the bottom of their file folders. Demotion is an intermediate option between keeping and deleting. It(More)
Whilst there has been substantial research into the support of meetings, there has been relatively little study of how meeting participants currently make records and how these records are used to direct collective and individual actions outside the meeting. This paper empirically investigates current meeting recording practices in order to both understand(More)
Social activity streams provide information both about the user's interests and about the way in which they engage with real world entities. Recent research has provided evidence of the presence of emergent semantics in such streams. In this work, we explore whether the online discourse of user's social activities can convey meaningful contextual(More)
People are often required to catch up on information they have missed in meetings, because of lateness or scheduling conflicts. Catching up is a complex cognitive process where people try to understand the current conversation without access to prior discussion. We develop and evaluate a novel Catchup audio player that allows "time-travel". It automatically(More)
We all encounter many documents on a daily basis that we do not have time to process in their entirety. Nevertheless, we lack good tools to rapidly skim and identify key information from within such documents. This paper develops and evaluates Interactive Compression (IC) techniques that allow users to dynamically configure the amount of information they(More)
1 Introduction AMI Meeting Facilitator is a system that performs topic segmentation and extractive sum-marisation. It consists of three components: (1) a segmenter that divides a meeting into a number of locally coherent segments, (2) a summa-rizer that selects the most important utterances from the meeting transcripts. and (3) a compression component that(More)
