Service resource search method and system based on attribute matching

Abstract

The invention provides a service resource searching method and a system based on attribute matching. The service resource searching method includes the following steps: search information of a user is obtained and is divided into a plurality of key words; a main synonym corresponding to each key word is searched in a synonym dictionary, and the key words are divided into a retrieval key word set and an adjustment key word set according to word classes of the key words; a first service resource type is obtained in a service resource attribute dictionary according to the retrieval key word set; a second service resource type is obtained in the first service resource type according to the adjustment key word set; when the attribute corresponding to the second service resource type is larger than the preset value, the final service resource is obtained through matching in the service resource corresponding to the second service resource type according to the plurality of key words and is fed back to the user. By means of the service resource searching method, the main synonym corresponding to each key word is obtained from the research information of the user, and resource search is carried out on the corresponding key words, so that the research hit rate is improved.

Description

technical field [0001] The present invention relates to the technical field of resource search, in particular to a service resource search method and system based on attribute matching. Background technique [0002] The matching and searching of service resources is to search for services that match the service resource request (SRR) from a large number of manufacturing service resources (MSR) in the manufacturing service resource library (SRD) according to the preset matching algorithm. However, due to the distribution and heterogeneous characteristics of the networked manufacturing environment, it is difficult to expect the exact consistency between SRR and MSR. [0003] In terms of distributed system service discovery, the current research is mainly based on the input and output of service description information, and some other information describing services are considered, such as Preconditions, Effects, etc. Although these provide an effective service resource search...

AI Technical Summary

Problems solved by technology

Compared with computing services, manufacturing services have the characteristics of long cycle, multi-party cooperation, knowledge, complexity, and diversity, so the above methods can only serve as a reference, and cannot be directly applied to manufacturing service resource matching and searching

[0004] In terms of discovery of manufacturing service resources, the current existing methods mainly focus on the keyword matching of the titles of service resources, but there is no research on the mining of service resource attribute knowledge in user search terms.

However, the currently widely used retrieval of service resource attributes is mainly the secondary retrieval of keyword matching retrieval results, or directly adopts the vertical search method. The retrieval user needs to confirm the retrieval conditions multiple times, which greatly reduces the retrieval efficiency.
