摘要:
 当前SPS在面对大量SOS时，无法帮助用户快速有效地寻找到功能匹配的SOS。文中在SPS2.0标准的基础上对SOS的发布和匹配进行了改进。首先使用SAWSDL规范对SOS描述文档WSDL及用户提交的观测任务进行扩充和语义标注，增强了服务描述能力和发现效率；其次通过在服务匹配阶段加入服务行为约束兼容性检测，既减小了匹配资源耗费，又保证了匹配精度；最后根据SOS的特点及各属性的权重值进行逻辑匹配，来减小匹配复杂度。实验结果表明，该方法较传统的SPS在查全率和查准率方面有较为明显的提高。
Abstract:
 At present,when the SPS faces a large number of SOS,it is unable to help users find the SOS that is function-matching effec-tively. In this paper,improve the method for SOS publication and matching based on SPS2. 0 standard. The expanding and semantic tag-ging for the WSDL of SOS description document and the observed task submitted by user is carried out by SAWSDL specification firstly, which can enhance the capacity of the service description and discovery efficiency. Then the checking of compatibility to the service be-havior constraints in the service matching stage is accomplished,not only can reduce the matching resources’ cost but also ensure matc-hing accuracy. Finally,based on SOS characteristics and the weight of each attribute value,the service matching is finished to reduce the complexity of the matching. The experimental results show that the approach,compared with traditional SPS,have evident improvement in recall and precision.
