Sequential pattern mining is an important data mining problem with broad applications. However,it is also a challenging problem since the mining may have to gen
Inherent heterogeneity and distribution of knowledge strongly prevent knowledge from sharing and reusing among different agents and software entities, and a fo
Data cube computation is a well-known expensive operation and has been studied extensively. It is often not feasible to compute a complete data cube due to the
With the development of Internet, frequent pattern mining has been extended to more complex patterns like tree mining and graph mining. Such applications arise
We discuss the projection temporal logic (PTL), based on a primitive projection operator, prj. A framing technique is also presented, using which a synchronizat
