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.
