Web service composition refers to the process of combining several web services to provide a value-added service. However, the component web services can't ensure reliable execution, because some services developed and operated by independent organizations may be deviate from the specification. In this paper, we propose a method that checks services reliability and ensures the best QoS combination...
Nowadays, the exploding number of functionally similar Web services has led to a new challenge of selecting the most relevant services using quality of service (QoS) aspects. Traditionally, the relevance of a service is determined by computing an overall score that aggregates individual QoS values. Users are required to assign weights to QoS attributes.

This paper concentrates on the evaluation system of hot topics in the online news about the emergency events. First, the overall technology framework of the system was established and description was formulated on the key issues need to be resolved prior to the evaluation of the hot topics. Focusing on the vector representation of the news documents and clustering algorithm of the news topics, a modified...
In the current evaluation model of information system, different field information systems are evaluated by standardized evaluation attributes, which can not meet quality for information system. In the paper the new evaluation mode is proposed which supports to customize evaluation attributes dynamically, and new TFAHP which has fuzzy evaluation adjustment attribute is also proposed, and approach...
