论文摘要
如今,由于收集数据的手段出现,大多数应用程序在流的形式下不断地产生信息。传感器和社交网络从不同的现实情况和相当大的速度收集了大量的数据和数量。越来越多的应用程序需要处理来自不同来源的异质数据流以及大型背景知识的处理。对于许多用例,仅使用数据流上的信息是不够的。语义复杂事件处理(CEP)系统通过基于经典规则的CEP系统发展,通过使用数据流和背景静态知识集成高级知识表示和RDF流处理。此外,CEP方法缺乏语义解释和分析数据的能力,该数据语义CEP(SCEP)试图解决哪种数据。 SCEP有几个局限性;其中之一与他们的高处理时间有关。本文提供了一个概念模型和分布式SCEP基础架构的实现,每个SCEP操作员可以处理部分数据并将其发送给其他SCEP操作员,以实现一些答案。我们表明,通过使用SCEP操作员的概念分解RDF流处理和背景知识,可以大大减少处理时间。
Today most applications continuously produce information under the form of streams, due to the advent of the means of collecting data. Sensors and social networks collect an immense variety and volume of data, from different real-life situations and at a considerable velocity. Increasingly, applications require processing of heterogeneous data streams from different sources together with large background knowledge. To use only the information on the data stream is not enough for many use cases. Semantic Complex Event Processing (CEP) systems have evolved from the classical rule-based CEP systems, by integrating high-level knowledge representation and RDF stream processing using both the data stream and background static knowledge. Additionally, CEP approaches lack the capability to semantically interpret and analyze data, which Semantic CEP (SCEP) attempts to address. SCEP has several limitations; one of them is related to their high processing time. This paper provides a conceptual model and an implementation of an infrastructure for distributed SCEP, where each SCEP operator can process part of the data and send it to other SCEP operators in order to achieves some answer. We show that by splitting the RDF stream processing and the background knowledge using the concept of SCEP operators, it's possible to considerably reduce processing time.
