Enhancing Rules in Active Databases via Relaxation Techniques

Abstract

In most decision support systems, events may be complex and temporal in nature. Further, human cognitive and expressive processes tend to use high-level, fuzzy concepts. We developed a cooperative sentinel that can detect complex events and support ECA rules with conceptual and approximate terms. A knowledge base will be developed to classify these conceptual terms based on application context and user types. The translation high-level concepts and approximate terms to low-level rules are leveraged on the proven matured CoBase relaxation technology. The system can operate on top of conventional relational databases. A prototype of the cooperative sentinel system has been developed at UCLA which is capable of triggering on high-level ECA rules with conceptual and approximate terms.
