The Shape of Different Public Online Meetings

Elia Tomadaki KMi, The Open University
The idea of virtual meetings is far from new, with the first video phone released by AT&T in the 60's, making it possible to conduct business with remote colleagues, reducing travel costs and environmental aggravation. Recently, videoconferencing has become part of long-distance learning environments. Professionals, educators and students use online meetings to enhance their collaboration from different parts of the world, as well as the learning experience. This seminar will explore the visualizations of a set of public online meetings produced by the FlashMeeting videoconferencing system; do the shapes tell the story of the meetings? A range of communication patterns emerge from various models of online meetings, such as seminars, interviews, moderated project meetings, peer-to-peer meetings, web-casts and video lectures, over a three-year experimental period. FlashMeeting is a light-weight video conferencing tool in a web-browser applet, transmitting video and audio of the broadcaster and regularly updating thumbnail images of the other participants, adopting a turn-taking approach with only one person talking at a time. Other interaction channels are provided via text chat, emoticons, as well as a voting system. The analysis shows the diverse use of video and text to achieve different communicative goals; text chat is mostly used for social support and building a community, whilst audiovisual interaction is mostly used for actual work collaboration. The choice of these communication channels also varies according to the meeting type. The results indicate that the exploitation of these communication channels may vary according to the nature of individuals; others prefer predominantly the audiovisual channel to make their point, whilst others remain silent contributing a great amount of text to convey their views and underline their participation in the event. The future work focuses on automatic recognition of meeting types and personalized visualizations, as well as on the detection of roles adopted by different participants and how they may change in time.

Semantic Web and Knowledge Services is...
Our research in the Semantic Web area looks at the potentials of fusing together advances in a range of disciplines, and applying them in a systemic way to simplify the development of intelligent, knowledge-based web services and to facilitate human access and use of knowledge available on the web. For instance, we are exploring ways in which tnatural language interfaces can be used to facilitate access to data distributed over different repositories. We are also developing infrastructures to support rapid development and deployment of semantic web services, which can be used to create web applications on-the-fly. We are also investigating ways in which semantic technology can support learning on the web, through a combination of knowledge representation support, pedagogical theories and intelligent content aggregation mechanisms. Finally, we are also investigating the Semantic Web itself as a domain of analysis and performing large scale empirical studies to uncover data about the concrete epistemologies which can be found on the Semantic Web. This exciting new area of research gives us concrete insights on the different conceptualizations that are present on the Semantic Web by giving us the possibility to discover which are the most common viewpoints, which viewpoints are mutually inconsistent, to what extent different models agree or disagree, etc...
Our aim is to be at the forefront of both theoretical and practical developments on the Semantic Web not only by developing theories and models, but also by building concrete applications, for a variety of domains and user communities, including KMi and the Open University itself.
