Complex event processing for sequence data and domain knowledge

The sequence data in real-life application exhibits logical semantic information among their items. However, traditional database techniques were not designed for both sequence data and semantic information and they are incapable of supporting analysis of sequence data with semantic information. In this paper, we present the design, implementation, and evaluation of a system that executes sequence data with semantic queries. We propose a complex event language that extends traditional event languages to meet the needs of semantic operation. To our knowledge this is the first paper to handle sequence data with domain knowledge. Experiment result shows that our approach is effective and efficient to solve the problem.
