Abstract

The equipment test data knowledge graph construction method comprises the following steps: (1) integrating existing equipment test data; (2) carrying out data cleaning and structured processing on the test data; (3) constructing a meta-model of test data; the meta-model comprises metadata information shared by various types of test data; (4) performing content identification and feature extraction on the test data through an informatization technology, and storing the test data according to a meta-model; (5) constructing data entities based on the test data, and establishing connection between the entities; and (6) based on a knowledge graph construction tool, importing all entities and relationships among the entities to form an equipment test data knowledge graph. According to the equipment test data knowledge graph construction method, the problems of equipment test data structuring, equipment test data visualization and the like are solved.

Description

technical field [0001] The invention relates to related technologies in the fields of big data and artificial intelligence, in particular to a method for constructing a knowledge map of equipment test data. Background technique [0002] The concept of knowledge graph was proposed by Google in 2012. It is mainly used to realize knowledge-based information retrieval. This technology has created a new mode of knowledge organization and knowledge display. Since then, research on knowledge graphs has become a hot topic at home and abroad, and research on the construction of knowledge graphs in various general fields has become increasingly mature. The typical multilingual knowledge graph DBpedia, whose data source mainly comes from Wikipedia, covers 125 languages ​​and has a wide range of applications around the world; the Probase knowledge graph constructed by Microsoft is also representative to a certain extent. The richest concept. Domestic scholars and institutions have als...
