In the last issue, I mentioned a CBR award to Cognitive Systems. Dan Corkill (cork@cs.umass.edu) notes that his Blackboard Technology Group, Inc., was awarded a Phase I SBIR entitled "Mixed-Paradigm Case-Based Reasoning using a Blackboard Architecture." A Phase I final report will be issued to DARPA in late September 1991.

Dan's project concerns control and problem solving in knowledge-based applications where CBR alone is insufficient. His GBB blackboard architecture integrates knowledge sources operating with CBR and other reasoning techniques. It seems that CBR and the blackboard paradigm share commonalities in indexing and retrieval (of cases and blackboard objects) and in large-grained control decisions (case selection and KS execution).

Dan says that he's always looking for new CBR applications. Please get in touch with him if you think of an intriguing possibility.
