The semantic web and web service take ontology into usage to describe the important concepts and relations among them. But the construction of ontology from scratch is costly and difficult. In this paper an approach is proposed to construct OWL ontology from XML document with the help of entity-relation model, and this approach will alleviate the(More)
One of the main benefits of web services is the dynamic composability, however how to achieve this is one of the current research challenges. Web service composition has been studied and, amongst other methods, the use of natural computing methods has been proposed previously. In this paper, we address the need for a fast response when computing the most(More)
Automatic Web services composition can be achieved by using AI planning techniques. HTN planning has been adopted to handle the OWL-S Web service composition problem. However, existing composition methods based on HTN planning have not considered the choice of decompositions available to a problem which can lead to a variety of valid solutions.In this(More)
Nowadays, the ubiquity of smart phones make them carry large amounts of personal sensitive information, but at the same time, there are also many Apps in Android APP market that target to collect users' sensitive data. So it becomes quite important to prevent users from the threat of privacy leakage. In this paper, we analyze the Android's privacy(More)

Service-Oriented Computing is benefit of interoperation among services. Current service-oriented computing research is much more concerning the low level interoperation among services, such as service discovery, service composition etc. However, the high level research issue-the feature interaction problem is also challenging the interoperation of(More)
Feature interaction has been identified as a problem in the telecommunications domain in the 1980s, but since it has been shown to be a problem of systems that are composed of individually designed components. Clearly Web service composition is a way of building services from independently designed components and hence is subject to the same problem. This(More)
Program bugs may result in unexpected software error, crash or serious security attack. Static program analysis is one of the most common methods to find program bugs. In this paper we present MLSA - a static analysis tool based on LLVM Intermediate Representation (IR), which can analyze programs written in multiple programming languages. MLSA combines(More)
Ontology mapping is a key technology to resolve interoperability between heterogeneous and distributed ontologies. So far, many efforts have been conducted to suggest ontology mapping model. The RFCA mapping model is one of them. In this paper, the problem of the reduction of formal context in the mapping process of the RFCA model is addressed, and a method(More)
