K-CEP: a knowledge-based complex event processing framework to manage qualitative spatiotemporal patterns

Dg2cep: An on-Line Algorithm for Real-Time Detection of Spatial Clusters From Large Data Streams Through Complex Event Processing

“…Considering CEP-based solutions for clustering position data stream, the majority of works encountered [62,63,64,65] provide generic range-query based primitives for detecting when a region is dense. For example, Mouza and Rigaux [62] reduce the problem of mobility pattern detection to regular expression.…”
