| 中文简介: |  有关应用程序领域的背景知识可用于事件处理中，以提高处理质量。语义丰富的想法是将背景知识合并到事件中，从而生成丰富的事件，在接下来的处理步骤中，事件处理引擎可以更好地理解这些事件。在本文中，我们通过计划多步骤事件丰富和处理，提出了一种有效的事件流丰富技术。我们的优化目标是在满足特定于应用程序的服务期望的同时，最大程度地减少事件丰富化成本。对事件充实进行了优化，以避免不必要的事件流充实，而不会丢失任何感兴趣的复杂事件。我们的实验结果表明，使用这种方法可以降低知识获取成本。 |
| 课程简介: | Background knowledge about the application domain can be used in event processing in order to improve processing quality. The idea of semantic enrichment is to incorporate background knowledge into events, thereby generating enriched events which, in the next processing step, can be better understood by event processing engines. In this paper, we present an efficient technique for event stream enrichment by planning multi-step event enrichment and processing. Our optimization goal is to minimize event enrichment costs while meeting application-specific service expectations. The event enrichment is optimized to avoid unnecessary event stream enrichment without missing any complex events of interest. Our experimental results shows that by using this approach it is possible to reduce the knowledge acquisition costs. |
