Smart meeting systems

Smart meeting systems, which record meetings and analyze the generated audio--visual content for future viewing, have been a topic of great interest in recent years. A successful smart meeting system relies on various technologies, ranging from devices and algorithms to architecture. This article presents a condensed survey of existing research and technologies, including smart meeting system architecture, meeting capture, meeting recognition, semantic processing, and evaluation methods. It aims at providing an overview of underlying technologies to help understand the key design issues of such systems. This article also describes various open issues as possible ways to extend the capabilities of current smart meeting systems.
