The invention discloses a matching method of semantic WEB service and a system thereof. Based on similarity between request and candidate service, the matching method and the system synthetically consider functional and non-functional factors, and introduce a phasing filtering mechanism. The matching method and the system adopt single-concept semantic matching algorithm, take depth, inheritance relation and binary relation into full account so that a body relationship structure is formed into a graphic structure rather than a tree-shaped structure, and the multiple inheritance problems and loop problems are processed during calculation of semantic distance based on the graph. The adopted multi-concept semantic matching algorithm has introduced a processing of repeated matching. During input and output matching, the number of parameters are taken into account, a method for calculating similarity in three levels is adopted, therefore,, the matching is more efficient; and the matching method and the system also takes into account factors of user preferences and service quality, therefore, the precision of matching and efficiency of response can be further improved.

The invention provides a semantic Web services system and applications thereof in the logistics field, and the system comprises a registration center, a service requester client and a service provider client, and the registration center, the service requester client and the service provider client are connected with one another, the services system is based on semantic Web, and the registration center, the service requester client and the service provider client are interactive with one another by a built service body. The invention solves a plurality of problems of difficult service discovery, very low service discovery efficiency, high consumption of human, material and financial resources and the like in the current third party logistics services, realizes the automatic discovery and automatic combination of services, greatly improves the efficiency of logistics service discovery and saves mass human, material and financial resources.

The invention discloses a gateway component, a network system and a working method of semantic telecom network capacity service, wherein, the gateway component consists of a semantic telecom network capability service gateway and a knowledge base of ontology which consists of a telecom service field ontology and a telecom network capability service application ontology, and the network capacity service gateway comprises three components: a telecom network capacity service semantization describing module, a telecom network capacity service WSDL describing module and a logic implementation module.

The invention relates to the technical field of web services. A multi-dimension semantic web service development method is used for achieving the aims that developers conveniently develop semantic web services meeting the multi-dimension semantic standard on the basis of a multi-dimension semantic model, development procedures of the developers are simplified, and a multi-dimension semantic development tool is integrated on an existing development platform eclipse. According to the technical scheme, the multi-dimension semantic web service development method includes the following steps of searching and result browsing, wherein the step of searching and result browsing includes service searching and body searching, and services and bodies in a services network (SN) are searched for respectively according to search conditions input by a user; (2) building a multi-dimension semantic web service module based on the SN, building new project engineering in a local operation environment of the user, and reusing corresponding operations or services according to the choice of the user. The method is mainly used for mechanical quantity machining measurement.

The invention discloses a method and a device for generating a semantic network service document. The method comprises the following steps of acquiring first interface structure information of an interested operation in a non-semantic network service document; acquiring second interface structure information of the semantic network service document; matching contents of the first interface structure information and the second interface structure information based on at least one of contextual information and description information of elements in the first interface structure information and elements in the second interface structure information, so as to establish a corresponding relation of all elements in the first and second interface structure information; generating an interface transformation engine for carrying out mutual transformation on the first and second interface structure information according to the corresponding relation, wherein information of interested operations at least in the second interface structure information, the interface transformation engine and the non-semantic network document form the semantic network service document, and the first interface structure information and the second interface structure information are respectively a set of elements having mutual relation information.

The invention discloses a method for extracting characteristic quantities of service sets on the basis of semantic Web service clusters. The method includes steps of counting bodies of the service sets to obtain body characteristic sets of the service sets; sorting the body characteristic sets according to a large-to-small body occurrence number rule; constructing a body characteristic tree of the service sets according to the sorted body characteristic sets of the service sets and generating the characteristic quantities according to the body characteristic tree. The method for extracting the characteristic quantities is extended and modified on the basis of an existing technology for dynamically acquiring characteristic quantities. The method has the advantages that attributes of the sets in a double-element model or even an n-element model are extended into function characteristics of the service sets according to occurrence numbers of the bodies in the service sets, and the bodies in the service sets are hierarchically organized.

The invention discloses a similarity based semantic Web service clustering labeling method. The method is characterized by comprising two parts of realizing semantic Web service similarity calculation and realizing a semantic Web service clustering labeling algorithm. During the semantic Web service similarity calculation, in combination with results of input / output (I / O) parameter mixed similarity calculation and service description keyword similarity calculation, a calculation result of semantic Web service similarity is comprehensively obtained, and the difference and similarity between service functions are reflected; and I / O parameters can directly describe functions of corresponding service modules and serve as measurement standards for calculating the semantic Web service similarity from a functional perspective. According to the method, the accuracy of similarity calculation can be improved and the performance of a service discovery system is further improved.

The invention relates to the technical field of web services and aims to improve availability of semantic web service descriptive models and achieve semantization of existing WSDL-described web services. According to the technical scheme, the method includes the steps of 1, acquiring functional semantics from a WSDL-described service document; 2, acquiring context semantics from the WSDL-described service document; 3, calling a web service, defining performance semantics of the web service according to MSDL standards; 4, acquiring time-space semantics of the service from the WSDL-described document; 5, acquiring technological semantics of the service from the WSDL-described document; 6, defining interaction semantics of the web service according to MSDL standards. The performance semantics of the multi-dimensional model describes quality attribute of the service. The method is mainly applied to web service technologies.
