The Vision
• Computers have become mediators of collaborations
– Email, chat rooms, blogs, wikis…
– A flood of available information
– Different modes of communication
• Let’s take advantage of such information
– Logs of conversations
– Archive of documents (email attachments, blogs, personal web pages…)
– Human-computer interactions
– Social aspect of the communication and collaboration
– Needs to work for multiple languages

The Project
• DISCUS started in 2003 as an IlliGAL & NCSA collaboration
• Supports innovation and creativity:
DISCUS: Distributed Innovation and Scalable Collaboration in Uncertain Settings
• Basic research components
– Competent genetic algorithms (HBGA, iGA)
– Advance chance discovery components
– Adapt and expand the analysis of social interaction
– Efficient data mining techniques for conversations
– Develop a social network analysis for creativity and innovation processes

The Project
• Technology development
– Infrastructure to support creativity and innovation processes
– Reusable repositories of analytic components
– Standardize heterogeneous data storage to boost interoperability
– Create hooks for non-intrusive usage and deployment
– Rapid adaptation cycle to new technologies
