Ontology-based Open API Composition Method For Automatic Mash-up Service Generation

As the web technology rapidly advances, web services are making significant strides in the Web 2.0 era which goes beyond the existing closed web services and enables one to open and share information freely. Web services arc usually provided in a form that uses Open Application Programming Interfaces (Open APIs) as the web service interface. As the number of open APIs increases, mash-up services that combine several Open APIs have begun to proliferate in the Web 2.0 environment. However, the current mash-up service generation method poses the problem in that normal users, who are not web service developers, have trouble generating mash-up services because Open API analysis and the programming skills are required. This kind of developer-centric service generation method is unable to satisfy normal service user demands for personalized services. As a consequence, we propose an ontology-based Open API composition method that can easily generate the mash-up services requested by users, based on ontology that can support semantic characteristics.
