Development of Retrieval Methods for RESTful Web Services Using Semantic Technologies

With the advent of Web 2.0, RESTful web services are becoming increasingly popular to emphasize the web as platform. There are already many RESTful web services and the number of services is increasing rapidly. Thus, it can be difficult to find specific services using keyword based retrieval. To solve this problem, a retrieval method was developed using semantic technologies based on RESTful web services. In order to accomplish this, first the system structure was defined and the description style was modeled based on the integrated search system for OpenAPIs; then semantic markup (tagging, semantic annotation) was added to the HTML description pages. Next, the RDF document was extracted from the HTML and stored in a service repository. Based on the keywords that are extended through ontology, the developed system provides more filtered and extended results than similarity based keyword searching systems.
