Semantic communication for distributed information coordination

We present a new paradigm for information coordination to support real-time collaboration, where the number of collaborating clients, their locations and interests are dynamic. The approach essentially applies the "pull" knowledge management model to distributed information management by defining semantically enhanced messages, and using state-based interaction techniques to communicate and replicate these messages. The approach underlies a Java based collaboration framework. The architecture of the framework and a preliminary experimental evaluation is presented.
