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 order to make the service composition with lower consumption resource and reduce execution time of service composition process, this paper proposes a method to optimize service composition model based on analysis of service composition execution log information and optimization of its Petri net model, which includes three steps: firstly, the log information and extracting related data are collected;...
Fast deployment of mobile Internet makes Web services often consumed under a multi-dimensional spatiotemporal model, wherein a specific service client could keep active while its location is changing. Recommending Web services for such clients must be able to predict unknown QoS values with the target client's service requesting time and location taken into account, e.g., Performing the prediction...
With the development of Service Computing and Big Data research, more and more heterogeneous data generated in the process of Service Computing attracts our attention. Combining correlated data sources may help improve the performance of a given task. For example, in service recommendation, one can combine (1) user profile data (e.g. Genders, age, etc.), (2) user log data (e.g., Click through data,...
Rapidly growing adoption of smartphones and other mobile broadband-enabled devices combined with flat-rate data plans are stretching the radio and backhaul capacity of many mobile networks to the limits. This creates technical and business issues for mobile operators and drives their interest in LTE. However, the prolonged financial downturn sets a pressure on operators to reduce CAPEX and OPEX of...
A profound analysis of all relevant business data in a company is necessary for optimizing business processes effectively. Current analyses typically run either on business process execution data or on operational business data. Correlations among the separate data sets have to be found manually under big effort. However, to achieve a more informative analysis and to fully optimize a company's business,...
Web services bonding with stateful resources are different from traditional web services. Because the state of those resources can be highly dynamic which make it difficult to discover and combine proper web services and fulfill clients' demand. This paper proposes a new method of web services description and registration based on WSRF (Web Service Resource Framework), aiming to provide real-time...
Executing Semantic Services requires, in contrast to traditional SOAP-based Web Services, frequent read and write accesses to graph-based semantic data stores - for instance, for the evaluation of preconditions or the materialization of service effects. Therefore, the overall performance of semantic service execution, in particular for composite services, is strongly affected by the efficiency of...
The US Navy has been supporting the demonstration of several IEEE standards with the intent of implementing these standards for future automatic test system procurement. In this paper, we discuss the second phase of a demonstration focusing on the IEEE P1232 AI-ESTATE standard. This standard specifies exchange formats and service interfaces for diagnostic reasoners. The first phase successfully demonstrated...
A construction and implementation technology of Distributed Decision Support System based on Business Integrated Network is described in this paper, First, we construct the framework of business intelligence decision support system(BIDSS) based on business integrated network, then we discussed the composition of the BIDSS in both the wired and wireless integrated network, the key technology to implement...
In order to realization electronic parts product appearance quality detection control, one kind of processor based on the intelligent knowledge automatic extraction and system intelligence modeling was presented. In the processor, wavelet-fuzzy technique and neural network technique are combined. Uses the fuzzy wavelet extraction image feature, and wavelet function is used as fuzzy membership function...
