Semantic UDDI registry system and its retrieval method

摘要

1. TECHNICAL FIELD OF THE INVENTION;The present invention relates to a semantic WDDI registry system and a search method thereof.;2. The technical problem to be solved by the invention;An object of the present invention is to provide a semantic UDDI registry system and a method for searching the same, which can search a web service semantically matched with a search based on semantics by extending the UDDI registry.;3. Summary of Solution to Invention;The present invention is a semantic-based search method in the semantic UDDI registry system, comprising: analyzing a registration request message received from an external system to verify validity; A first determining step of extracting a registered word from a valid registration request message and determining whether the registered word is a keyword-based or semantic-based registered word; As a result of the determination in the first determination step, if the registered word is determined based on the keyword, the web service information is registered in the UDDI database. If the registered word is determined based on the semantic word, the web service information is registered in the ontology (OWL-S) database for the web service. Later transmitting a registration response (result) message to the external system; Interpreting a search query message received from the external system to verify validity; A second determining step of extracting a query from a valid search query message and determining whether the query is a keyword-based query or a semantic-based query word; And searching the web service information in the UDDI database when the query word is determined based on the keyword as a result of the determination of the second determination step. Ontology for the web service (OWL-S) Searching in a database and delivering a search result message to the external system.;4. Important uses of the invention;The present invention is used in a web service information retrieval system.;Semantic UDDI Registry, Extensions, Semantic Search, Web Services, Ontology for Web Services (OWL-S)
