Research on Technology of Web Services Composition in Mobile Devices Based OWL-S

In order to let mobile devices get Web services easily under ubiquitous computing environment. This paper proposes a method that based on OWL-S technology for accessing to Web services by Web services´ combination. First of all, Using OWL-S to describe Web service´s semantic, which is focus on aspect of S-IOPRD (Semantic based Inputs, Outputs, Preconditions, Results and Domain); Secondly, we design a architecture, which is based on OWL-S, and detail each module functions of topology framework and system architecture; Then, we introduce the prototype system; Finally, as results of the analysis of the examples and examples´ data, we ensure mobile devices access to Web services continuality and stability.
