Embodiment Construction

[0060] The inventive method comprises the following three steps:

[0061] (1) Use semantic operators to express the user's semantic information on search conditions;

[0062] (2) Map semantic operators into corresponding search operation sequences;

[0063] (3) Execute the search action according to the generated search operation sequence to obtain the search result.

[0064] The semantic operators include: semantic equivalence, semantic instantiation, semantic conceptualization, semantic expansion and semantic contraction. The semantic operator syntax is:

[0065] [|][|]

[0066] Among them, the semantic annotation refers to the semantic annotation elements under various semantic Web service description frameworks, the semantic operator is one of the five semantic operators defined in the present invention, and ontology-defined concepts or ontology-defined individuals refer to the concepts defined in the application domain ontology or individual. use C i Represent ontol...

Abstract

The invention relates to a resource search method for semantic-oriented Web services. The method comprises the following steps: (1) applying semantic operational characters to express semantic information of users on search conditions; (2) mapping the semantic operational characters into corresponding search operation sequences; and (3) executing search action according to the generated search operation sequences, and obtaining search results. The semantic operational characters are used for establishing a search condition expression used in a semantic Web service search engine, and the search operation sequences are concrete search action sequences generated after the semantic Web service search engine processes the semantic operational characters. The five semantic operational characters provided by the invention can be used for establishing the search condition expression so as to contribute to accurate expression of semantic information included in the search conditions by users; and the four search operation sequences convert the semantic operational characters processed by the semantic Web service search engine into concrete search operations, and semantic Web service resources required by the users are obtained.

Description

technical field [0001] The invention relates to a semantic Web service-oriented resource search method, which belongs to the technical field of Internet information retrieval. Background technique [0002] Semantic Web service is the product of the combination of two important branches in the World Wide Web technology revolution: Semantic Web and Web service. The main research content of Semantic Web Services is to use more abundant and distributed semantic description elements for dynamic distributed computing. By using relevant semantic description information, more flexible automated service provision and usage methods can be obtained, more powerful software development tools can be developed, and methods for constructing semantic services and creating service-based software solutions can be obtained. It will take time for Semantic Web services to be popularized and widely recognized by the industry, and researchers engaged in academic research on Semantic Web services n...
