Problems solved by technology

However, there is no specific description of QoS in the semantic Web service discovery method, and QoS monitoring still requires manual participation, so it still cannot support batch and automatic service calls and QoS information acquisition

Embodiment Construction

[0052] The technical scheme adopted in the present invention is:

[0053] (1) Analyze the WSDL file of the Web service to obtain the service name, service interface name, service interface description, service parameter name, and service parameter type;

[0054] (2) Use the DBpedia ontology to label service parameters, including establishing a Web service labeling model based on DBpedia associated data, refine and clean the parameters of the Web service parameter layer, and use the DBpedia Spotlight application to associate each cleaned parameter of the Web service with the A suitable DBpedia instance data or ontology conceptually (see patent 201310172375.1);

[0055] (3) Judging whether the labeling result is an ontology concept, if yes, then perform step (4); if not, then perform step (10);

[0056] (4) Use the marked ontology concept as the object, the predicate as the rdf:type attribute of RDF, and generate the SPARQL statement according to the SPARQL grammar rules;

Abstract

The invention relates to the technical field of Web service and aims to achieve monitoring on the availability and response time of Web service and other QoS information, greatly relieve the load of manual parameter input, save time and expense and ensure QoS accuracy and timeliness. The technical scheme includes that a semanteme-based Web service automatic calling and QoS information monitoring method includes steps of: (1) parsing a WSDL (Web Services Description Language) document of Web service; (2) building a Web service tagging model based on DBpedia associated data; (3) judging whether the tagging result is an ontology concept; (4) making the tagged ontology concept to be the object; (5) sending a request with an SPARQL (Simple Protocol And Rdf Query Language) packaged in to a DBpedia SPARQL protocol terminal http: / / dbpedia.org / sparql by aid of Java Script. The semanteme-based Web service automatic calling and QoS information monitoring method is mainly applied to Web service.

Description

technical field [0001] The invention relates to the technical field of Web services, in particular to a method for automatically invoking Web services based on semantics and an automatic service QoS monitoring method. technical background [0002] Web service is the main technology to realize service-oriented computing, and it is the best realization of service-oriented architecture (SOA). Service interface description, such as the interface in machine-readable format defined by Web Services Description Language (WSDL), defines the operations supported by the software from two aspects of data and functions, and describes the service operating environment, input / output parameters and other information. At present, SOA software testing has been widely concerned by researchers and developers. Three factors must be considered in service-based software system testing: automation, dynamic collaboration capabilities, and service-autonomous computing. Service reconstruction require...
