With the fast growing number of web services and consumers, selecting a suitable service for the consumer is becoming a crucial issue. Quality of Service (QoS) plays a significant role for both service and consumer in determining requirements. A number of models have been proposed for service selection by considering QoS parameters. In this paper we propose a service selection algorithm by considering...
Neural network is easy to fall into the minimum and over-fitting in the application. The paper proposes a novel dynamic weight neural network ensemble model (DW-NNE). The Bagging algorithm generates certain neural network individuals which then are selected by the k-means clustering algorithm. In addition, for the integrated output problems, the paper proposes a dynamic weight model which is based...
Many users often perform searches in unfamiliar domains and these search experiences are often unsatisfactory since the users are lack of domain-specific knowledge. In this paper, we present a concept based retrieval method to deal with domain-specific searches. Three groups of domain-specific concepts are extracted from the online resource. The following experiments on three domain-specific test...
To meet the increasing demands of multiple QoS levels services, customer perception-based service quality evaluation should be the premise guarantee in end-to-end service optimizing process. However, in the practical application, due to the intrinsically subjective perception of customers and the objective condition of service quality, conventional customer evaluation approaches can hardly reflect...
