Abstract : The AASERT grant,'Intelligent Access to Scalable Cooperative informations Systems' enabled the UCLA graduate student Michael Minock to address his dissertation toward the role of Explanation and paraphrase technology in Cooperative information Systems. Given the requirement of providing explanation for CoBase answers, this work furthered the overall mission of our parent DARPA contract. In the first year of the AASERT we built a prototype of CoBase capable of generating explanations and descriptions which we demonstrated at the 1994 DARPA Planning Workshop in Tuscon. In the second year the technology in the prototype was extended and transferred to a modular explanation server and integrated with the full CoBase system. The extensibility this system was established by providing explanation for CoBase over Electronic Warfare and Medical image domains. Currently the Explanation system is undergoing rigorous testing by other graduate students in our group. Theoretical work focused on the representation of CoBase's trace and the process of computing explanations and generating descriptions. We have produced an instance classification system over which explanation is provably complete, correct, and minimal. Progress has also been made toward an Object-Oriented framework that enables complete and correct description and explanation for applications such as CoBase.
