In this paper, we propose an efficient QoS management approach for QoS-aware web service composition. In the approach, we classify web services according to theirs similarity and then design a QoS tree to manage the QoS the classified web services. Besides, by querying the managed QoS, we propose a QoS-aware web service composition via a particle swarm(More)
To efficiently support customers to find web service which satisfies the non-functional requirement, a distributed quality of service(QoS) index framework is proposed in this paper. The framework consists of two kinds of structured distributed system, one is chord overlay network which is assigned to classify the web services according to the similarity of(More)
In this paper, we propose a Hadoop-based approach for Web service management in Telecommunication and Internet domains. The basic idea of this approach is to adopt two components of Hadoop, HBase and MapReduce, to manage Web services. In HBase, we establish a HBase table based on request interface, and design a non-functional property index mechanism based(More)
Most of trustworthy web service selection simply focus on individual reputation and ignore the collaboration reputation between services. To enhance the collaboration trust during web service selection, a reputation model called collaboration reputation is proposed. The collaboration reputation model is built on web service collaboration network (WSCN), and(More)

Community mining has been the focus of many recent efforts on complex networks, and the genetic algorithm with low time-complexity is widely used in this discipline. To enhance the performance of genetic algorithm for community detection, the modified crossover operators which are more suitable for community detection is proposed in this paper, and the(More)
