With the emergence of a variety of data cloud services, especially composite data cloud services, service trustworthiness problem is particularly prominent. Data cloud service credibility becomes focus of cloud service consumers. Data cloud service is essentially a Web service and its quality is associated with the Web service evolution process. In this paper, considering how provenance information,...
In this paper, we design and implement a high quality audio material retrieval system in view of the shortcomings of existing professional audio retrieval platforms. The aim of our system is to provide an integrated audio retrieval solution for audio editing staffs. Firstly, for hybrid architecture, the server of the system described in this paper publishes services by Web Services when realizing...
Making good use of Service Level Agreements (SLA) becomes crucial for an enterprise both to provide value added products and services to customers and to protect the interest of parties involved in the business activities. Well formed and effective structural representation and management of SLAs in conceptual modeling can greatly support the understanding and communication of service development...
Non-trivial trails in choosing the right data mining algorithm and tuning its arguments for a data set is one of most trivial tasks for data mining users. Sharing and mining users' experiences in using data mining tools can give valuable clues for a new user. This paper presents a description framework for the data provenance in a data mining grid platform and design two kinds of methods for representing...
With the large growth of web service resource, the current semantic interaction model couldn't solve the network problems. This paper gives the semantic definition and relationship of network resources. With the definition of network influence factor for control-flow and dataflow, it gives the formal algorithm for web service balance of request and response. Also it analyzes the performance of network...
With the wide use of Web Services in Enterprise Application Integration, the issues of Web Services security are becoming increasingly prominent. For the security issues of data, a Web Service security model based on the security transport of SOAP message at application layer is proposed, implements the secure identity authentication and permission Management, pledges the confidentiality, integrality...
Within a business environment, the quality of service (QoS) is one of the most important factors for differentiating between similar services. It is very important for service providers to control and manage the QoS for their offered services and for service consumers to validate the services they use. The Service Level Agreements (SLAs) plays an important role for maintaining the Quality of Service...
A novel architecture is presented for the matching of Web-services based on the extraction of interpretation graphs from natural language text. The graphs of candidate services are compared to that of the query using a numerical node-node similarity calculation based on the structure of the graphs. The similarity score of their best alignment with the query may then be used to rank the candidates.
At present, the service composition has been a popular research. It is unrealistic to manually analyze and compose the existing services appearing with tremendous growth recently. So, many applications and research about composite services emphasize on semi-automatic mode. In semi-automatic service composition, developers should construct the process model according to concrete application requirement,...
With the rapid development of SOC (Service oriented computing), the automated service composition has become an important research direction. Through automated service composition, business processes need not to be constructed in advance, which helps to improve the flexibility of service composition. The current research on automated service composition is mainly based on AI techniques, and a common...
With the large growth in number of asynchronous call of Web service, current SOA architecture infrastructure becomes insecurity and inefficiency. This paper proposes a semantic model and an AMHKA (asynchronous message host key authentication) algorithm of asynchronous call for Web service security. With the definition of OSIABSD (optimize security invoking algorithm based on service domain), it gives...
With the fast development of Internet and rapid acceptance of Web Service technology, more and more service resources have emerged. Service composition which integrates the functionalities of different services is a promising technique for developing applications across multiple organizations. However, in a distributed, dynamic and autonomous environment, such as a service composition-based system,...
As the amount of Web services over the Internet grows continuously, these services can be interconnected to form a service overlay network (SON). On the basis of SON, building value-added services by service composition is an effective method to satisfy the changeable functional and non-functional QoS (quality of service) requirements of customers. However, the previous research on QoS- aware service...
