LogCEP - Complex Event Processing based on Pushdown Automaton

LogCEP - Complex Event Processing based on Pushdown Automaton

Complex (or Composite) event processing systems have become more popular in a number of areas. Non-deterministic finite automata (NFA) are frequently used to evaluate CEP queries. However, it is complex or difficult to use the traditional NFA-based method to process patterns with conjunction and negation. In this paper, we proposed a new CEP system LogCEP using pushdown automaton to support eff...

Visual Spike Processing based on Cellular Automaton

Complex Event Processing

Complex Event Processing (CEP) has evolved into the paradigm of choice for the development of monitoring and reactive applications. It also has a strong impact on future information systems and the way we subscribe to and consume information. Besides being a highly active research field, CEP already plays an important role in many application areas like logistics, energy management, finance, or...

Semantic Complex Event Processing

Recently a number of approaches to combining Semantic Web technologies such as RDF(S) and OWL with complex event processing have been proposed. This paper examines these approaches, by emphasizing their advantages and challenges. Key-Words: Complex event processing (CEP), semantic complex event processing (SCEP), ontologies.

The Impact on Complex Event Processing

There is increasing demand for complex event processing of ever-expanding volumes of data in an ever-growing number of application domains. Traditional complex event processing technologies, based upon stream database management systems or publish/subscribe systems, are adept at handling many of these technologies. A growing number of hybrid complex event detection scenarios require features of...
