The OpenAPI retrieval system has been developed applying semantic web technologies as the typical information retrieval method had. The semantic web technologies applied in the system are tagging and semantic-annotation. However, these methods are difficult for the non-technical general users to use and the probability of failure is high. To solve these problems we suggest improved methods for the tagging and semantic- annotation. Tagging turn human-readable service description to machine-readable one by adding tags into the page. Through the use of XHTML and DTD modification, auto-completion and auto-view are enabled. Semantic-annotation means to input related semantic information into parameters in the service description. The java-based tool providing methods of target parameters selection and the ontology viewer is developed for annotating easily. Tagging and semantic-annotation are applied and tested through the test-bed system. These improvements enabled non-technical general users to applying semantic information to the OpenAPI retrieval system.
