A Method for Service Dynamic Discovery Based on SOA4All Architecture

In the environment of Semantic Web of Things, services presenting new features such as the large amount of devices services, the mobility and the highly dynamic information. Due to these new features, the service discovery method based on keyword comparison in traditional SOA architecture, will lead to the low accuracy of service discovery. To solve the above-mentioned problems, a method based on SOA4All architecture for service dynamic discovery is proposed in this paper. The user-centric feature is enhanced by annotating the semantic information to the service to build a service description tree, as well as using the reasoning machine to make the reasoning of currently context. Moreover, SOA4All architecture is used to promote dynamic communication and collaborative access between services. Some experimental examples of weather service on Google show that this method significantly improve the accuracy of service discovery and make a large degree of satisfaction to meet user requests.
