Meeting browsing - State-of-the-art review

Meeting, to discuss and share information, take decisions and allocate tasks, is a central aspect of human activity. Computer mediated communication offers enhanced possibilities for synchronous collaboration by allowing seamless capture of meetings, thus relieving participants from time-consuming documentation tasks.
