Abstract
Web services are becoming prevalent nowadays. Finding desired Web services is becoming an emergent and challenging research problem. In this paper, we present WSExpress (Web Service Express), a novel Web service search engine to expressively find expected Web services. WSExpress ranks the publicly available Web services not only by functional similarities to users’ queries, but also by nonfunctional QoS characteristics of Web services. WSExpress provides three searching styles, which can adapt to the scenario of finding an appropriate Web service and the scenario of automatically replacing a failed Web service with a suitable one. WSExpress is implemented by Java language and large-scale experiments employing real-world Web services are conducted. Totally 3,738 Web services (15,811 operations) from 69 countries are involved in our experiments. The experimental results show that our search engine can find Web services with the desired functional and non-functional requirements. Extensive experimental studies are also conducted on a well known benchmark dataset consisting of 1,000 Web service operations to show the recall and precision performance of our search engine.
如今，Web服务变得越来越流行。寻找所需的Web服务正在成为一个新兴的、具有挑战性的研究问题。在本文中，我们提出了一种新的Web服务搜索引擎WSExpress (Web Service Express)，用于表达地查找期望的Web服务。WSExpress不仅根据与用户查询的功能相似性对公开可用的Web服务进行排名，而且还根据Web服务的非功能QoS特征对其进行排名。WSExpress提供了三种搜索样式，可以适应寻找合适的Web服务的场景和用合适的Web服务自动替换失败的Web服务的场景。WSExpress是用Java语言实现的，并利用真实的Web服务进行了大规模的实验。来自69个国家的总共3,738个Web服务(15,811个操作)参与了我们的实验。实验结果表明，我们的搜索引擎可以找到具有所需功能和非功能需求的Web服务。我们还在一个由1,000个Web服务操作组成的著名基准数据集上进行了广泛的实验研究，以展示我们的搜索引擎的召回率和精度性能。
