Service-oriented Computing (SOC) has become one of the most preferred distributed computing paradigms which utilize services as elements for designing and developing application systems. In SOC, consumers who have different functional and non-functional requirements might consume services offered by various providers. Faced with the increasing number of Web services and the diversity of service consumers'...
The global optimal Web service selection based on quality of service (QoS) in cloud environment has become a research focus when there are lots of the same or similar services. In this environment, it is possible that many service users request the same or similar services at the same time, which will result in users' unsatisfied requirement and services' load imbalance. The existing service selection...
This paper presents the first computer aided software analysis tool based on HOOMT (High Order Object-oriented Modeling Technique), which provides facilities for structured object-oriented analysis by integrating structured analysis and object-oriented analysis. It contains a graphical user interface for HOOMT-based modeling, supports modeling information management, and provides functionalities for...
The trustworthiness of service providers plays an important role when a consumer selects a service. This paper studies the problem of how to efficiently search and select trustworthy service providers for users in social networks consisting of service providers and consumers. A trust value between two participants can be derived by existing methods from the optimal trust path between them in a social...
Dynamic Web service selection with global QoS optimization in Web service composition is a critical issue in Web service composition. In order to solve the problem, based on intelligent optimal theory of particle swarm optimization (PSO) algorithm, we propose a strategy PSO-GODSS (global optimization of dynamic Web service selection based on PSO) algorithm to implement Web service selection with QoS...
For the problems of Chinese text similarity calculation based on word frequency statistics, this paper proposed a method by using machine translation to translate Chinese text into English text, indirectly calculate similarity of given texts. This method can avoid some shortcomings of Chinese word segmentation and utilize the advantages of the natural word segmentation of English, and also can use...
Web service selection based on quality of service (QoS) has been a research focus in an environment where many similar web services exist. Current methods of service selection usually focus on a single service request at a time and the selection of a service with the best QoS at the user's own discretion. The selection does not consider multiple requests for the same functional web services. Usually,...
