中文摘要：

如何准确地发现目标服务是服务计算研究的关键问题。传统的服务发现方法由于没有考虑服务任务情景的适用性，查询精度仍有较大上升空间。基于此，提出包含任务情景的服务发现方法，以自定义本体论为基础，引入结构化概念实例模式来描述任务情景。实验数据表明，该方法提高了服务发现的精度。

英文摘要：

The key problem in service computing domain is to find target service precisely. Due to not considering the compatibility of task circumstance, the precise of traditional service discovery method can be improved. This paper proposes a task circumstance imported service discovery method, which imports structured concept instance pattern to describe task circumstance. Experimental data shows that the proposed method outperforms others in terms of precision.
