Abstract


Based on a large amount of engineering machinery fault data collected by Tianyuan Co.,
this paper provides its formal definition aiming at the fault knowledge graph. This paper has also
studied the technical details of knowledge acquisition and knowledge fusion in the field of
engineering machinery and equipment failures based on multiple data sources. Then the paper
proposes a data-driven iterative automatic construction method of knowledge graph, and explores the
intelligent application of fault knowledge graph, including template-based fault knowledge
question-answering and troubleshooting assistance based on knowledge graph reasoning.

Keywords


Knowledge graph, Multiple data sources, Knowledge acquisition, Knowledge fusion, Question-answering, Knowledge reasoning.
