Embodiment Construction

[0044] The present invention is mainly based on the knowledge map construction method, and proposes a knowledge map construction method for closed switchgear. Through the method, the knowledge extraction of the scanned image of the quality inspection report can be realized, and the automatic acceptance of the closed switchgear can be completed.

[0045] The method provided by the invention can use computer software technology to realize the process, see figure 1 . Embodiment Taking the knowledge extraction from the scanned image of a closed switchgear quality inspection report as an example, the process of the present invention is described in detail, as follows:

[0046] A method for building a knowledge map for closed switchgear, comprising the following steps:

[0047] Step 1, perform optical text recognition on the scanned image of the standard closed switchgear quality inspection report, and extract the text information describing the equipment in the scanned image;

Abstract

The invention belongs to the technical field of computers and information services, and relates to a knowledge graph construction method and system for closed switch equipment. The method comprises the following steps: identifying text data from a scanned image of a closed switch equipment quality inspection report; performing text labeling on the recognized text information described by the equipment, and labeling a triple relationship (entity, relationship and entity attribute) describing equipment attribute in each sentence; constructing a relation triple extraction model based on BERT; based on the trained triple extraction model, carrying out the relation extraction on the test sample, obtaining a triple relation describing equipment attributes, constructing a relation knowledge graph, comparing the relation knowledge graph of the test sample with a standard equipment relation knowledge graph, and achieving equipment inspection. The method can be widely applied to the fields of character extraction, naming recognition, relation extraction, knowledge graph construction and the like of scanned images.

Description

technical field [0001] The invention belongs to the technical field of computers and information services, and in particular relates to a method and system for semantic analysis and knowledge graph construction of specific scanned images. Background technique [0002] Knowledge graphs describe concepts, entities and their relationships in the objective world in a structured form, and have become an important task for structured knowledge integration. [0003] The quality inspection report of enclosed switchgear is an inspection report for specific equipment, including a comprehensive report on the test results of the overall performance, component performance, and operating performance of enclosed switchgear. At this stage, the acceptance of the quality inspection report of closed switchgear needs to be completed manually, which consumes manpower. By constructing the standard knowledge map of the quality of closed switchgear, the intelligent understanding and automatic accep...
