报告会主题
服务计算最新研究进展
服务计算是一门桥接商业服务与信息技术服务的跨学科的新兴科学技术。在服务计算中,服务作为基本的组件支持快速、低成本的业务流程整合和分布式的应用开发。如何利用信息技术来支持有效地创建、营运、管理与组合服务,引起了相关领域研究人员的广泛兴趣。本报告会将介绍服务计算的最新研究进展,包括如何挖掘和利用服务计算环境中的数据,如何对服务的质量进行管理等。报告会将邀请服务计算领域的专家学者,从不同视角进行深入探讨和分析。

Mining and Exploring Data in Service Computing
特邀讲者:吴健

报告提要:
The development of cloud computing and mobile computing poses a lot of opportunities to service oriented computing. In particular, the knowledge hidden in the explosive growth of service related data provides a chance to handle some difficult problems in service computing. In this talk, we will focus on the problem of service recommendation, and utilize two kinds of service related data to improve its performance. In the first scenario, we propose to improve the recall performance of service recommendation by using a Web service clustering framework named WSTCluster, in which WSDL documents and social tagging data are employed. To handle the spam tags and cold-start problem, a tag relevance measurement Mechanism, i.e. WS-TRM, is proposed. In the second scenario, considering the user knowledge and behavior information hidden in service historical execution records, we employ a bayes theorem based approach on the historical data to estimate the probabilities of candidate services for the purpose of facilitating service recommendation. A graph-mining based approach is also proposed to model and explore the historical service composition records. Finally, we will summary a series of work of our group in service discovery and recommendation.

QoS Management of Service Computing
特邀讲者:郑子彬

报告提要:
Web service is becoming a major technique for building loosely-coupled distributed systems. Quality-of-Service (QoS) is usually employed for describing the non-functional characteristics of Web services and employed as an important differentiating point of different Web services. With the prevalence of Web services on the Internet, Web service QoS management is becoming more and more important. In this talk, we will first propose a distributed QoS evaluation framework for Web services, named WS-DREAM. Inspired by the recent success of Web 2.0, our evaluation framework employs the concept of user-collaboration. Since Web service evaluation is time and resource consuming, and in some scenarios, Web service evaluation may not be possible (e.g., the Web service invocation is charged, too many service candidate, etc.). Therefore, Web service QoS prediction approaches are becoming more and more attractive. In order to prediction the Web service QoS as accurate as possible, we propose three prediction methods. Finally, based on the predicted QoS values, we propose two methods for building fault tolerance Web services.
