Product design knowledge service method and device

Abstract

The invention discloses a product design knowledge service method and device. The method comprises the following steps of: obtaining knowledge demand elements to construct a knowledge demand model; carrying out semantic extension to obtain a primary knowledge demand hierarchical structure with semantics; carrying out modification to generate an ultimate knowledge demand hierarchical structure; matching a semantic space to obtain candidate sematic space units; carrying out analytical reasoning on the basis of an SWRL rule so as to generate a POV network; solving an optimum topological sequence of the POV network so as to form a semantic space of a knowledge service scheme; and configuring associated knowledge resources. The device comprises a construction module, a semantic extension module, a modification module, a matching module, a generation module and sorting and association module. According to the method and device, modeling is carried out on the basis of knowledge demands, SWRL reasoning and a digraph theory are combined to mine logic relation and connotations between knowledges to the greatest extent from semantic level, so that the appreciation of the knowledges is realized and the effectiveness of required knowledge pushing result in the product design process is improved.

Description

technical field [0001] The invention relates to the technical field of product design, in particular to a product design knowledge service method and device. Background technique [0002] In the era of knowledge economy, how to use the existing product design knowledge to create more value is the key problem that all design and manufacturing enterprises face. Traditional product design knowledge service methods generally include knowledge retrieval and push, and the results of these two knowledge service methods are often just a simple knowledge list. However, product design knowledge has complex semantic associations. Using this traditional retrieval or push method, because it is not closely integrated with product design business and ignores the logical relationship between knowledge itself, results in redundant retrieval and push results. In addition, the accuracy of the knowledge provided is poor, and designers often need to spend a lot of energy to screen one by one fr...

However, product design knowledge has complex semantic associations. Using this traditional retrieval or push method, because it is not closely integrated with product design business and ignores the logical relationship between knowledge itself, results in redundant retrieval and push results. In addition, the accuracy of the knowledge provided is poor, and designers often need to spend a lot of energy to screen one by one from the pushed knowledge list, and it is difficult to find the real knowledge they need

[0003] In summary, the product design knowledge service in the prior art has the technical problem of poor validity of the knowledge results pushed and retrieved
