Embodiment Construction

[0039] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0040] Such as Figure 1-5 As shown, a method for establishing a domain knowledge base applied to the production process of the discrete manufacturing industry includes the following steps:

[0041] Step S1, text corpus management, obtain big data platform data resources through the interface. Convert corpus data with diverse formats into a consistent or unified format that can be further processed;

[0042] Step S2, text preprocessing, realizes the initial processing and information extraction of text data. The specific contents include: domain text word segmentation, domain vocabulary part-of-speech tagging, significance calculation, domain keyword extraction, domain entity extraction, and domain vocabulary automatic classific...

Abstract

The invention discloses a domain knowledge base establishing method applied to a discrete manufacturing industry production process. The domain knowledge base establishing method comprises the following steps of S1, text corpus management; S2, text preprocessing; S3, knowledge network retrieval; S4, domain knowledge base construction. According to the method, the domain knowledge base is established, and an effective sorting algorithm is adopted, so that the retrieval results in the domain knowledge base are sorted reasonably, and the retrieval results can be sorted according to relevancy, dates or sources and the like. When retrieval needs to be carried out by means of empirical data such as a word list, result arrangement is scientific and reasonable, and secondary retrieval can be carried out on retrieval results. And screening of multiple conditions is supported, and the average retrieval time is controlled within 0.5 second. Besides, the method supports retrieval of files of different formats such as PDF, word and excel, supports full-text retrieval of resources, supports retrieval in a word list and a knowledge base, calls a visualization tool and provides a visualization display result.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a method for establishing a domain knowledge base applied to the production process of a discrete manufacturing industry. Background technique [0002] As an important processing method in the production process of parts, part painting has the functions of anti-corrosion and decoration. The heat meter factory paints more than 1.7 million parts every year. Due to the old processing methods and low automation, problems such as quality fluctuations, artificial occupational health, cumbersome data distortion of special process quality records, and in-depth mining and insufficient utilization of process data have become prominent. There is an urgent need for automation and informatization transformation, using machines to replace manual logistics transportation and spraying, to achieve rhythmic production in the spraying process, real-time collection and feedback of production data,...
