Problems solved by technology

Compared with the calculation grid, the manufacturing grid (MGrid) has the characteristics of long cycle, multi-party cooperation, knowledge, complexity, diversity, etc., so the above methods can only serve as a reference, and cannot be directly applied to MGrid resource service matching and searching
[0004] In terms of resource service discovery in distributed manufacturing systems, for MGrid resource service matching and searching, the existing research mainly stays on performance QoS indicator

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] The present invention includes a resource service matching and search implementation framework based on description information matching similarity, and four different types of resource service description information (text ontology concept, sentence, numerical value (including numerical interval and fuzzy number), entity class (data structure) concept) similarity matching algorithm and then propose a four-level resource service matching model. see figure 1 , the resource service matching and search implementation framework is mainly composed of three parts:

[0023] (1) The resource service information parser Parser is mainly responsible for classifying and extracting the task description (or resource service request information) submitted by the user and various information descriptions in the resource service information to be selected in the resou...

Abstract

The invention relates to a descriptive information matching similarity-based resource service matching and searching method. Specifically, in the method, after digital manufacture resource service description, resource service descriptive information is further divided into types of character body concept, sentence, digital value, entity concept and the like, and corresponding similarity matching algorithms are designed respectively; and on such a basis, resource service matching searching is realized by the steps of basic matching, input and output matching, quality of service matching and comprehensive matching. The method mainly aims to solve the problem that the matching and searching of the descriptive information types of the digital value, sentence, entity concept and the like are not taken into account in the conventional resource service matching. In the method, a manufacture resource service matching and searching realization frame, the similarity matching algorithm for the different types of service descriptive information, a multilayer resource service matching model and realization algorithms are involved. The method has the advantage that: a distributed system supporting semantics and SOA is hierarchically clear and has high compatibility and expansibility.

Description

technical field [0001] The present invention relates to a resource service matching and searching method based on description information matching similarity, that is, a distributed system that supports semantics and SOA, based on a similarity matching algorithm between different types of resource service description information A resource service matching and searching method is implemented by dividing the resource service matching search into steps such as basic matching, input / output (I / O) matching, QoS matching, and comprehensive matching. The invention belongs to the technical field of distributed manufacturing system information integration. Background technique [0002] The matching and searching of resource services means that in order to realize a certain function (or to meet the service request of the resource service demander RSD), according to the preset matching algorithm, from the numerous resource services (MRS) in the resource service information center RSIC ...
