In view of the problem that the public data in the field of mine hoist fault is less and the fault knowledge is difficult to be effectively utilized, this paper proposes a method for constructing a mine hoist fault knowledge graph. This method firstly introduces a fault text classification process to deal with the information redundancy problem existing in the target corpus. Then it uses dictionary embedding BERT and BiLSTM-CRF combination for entity recognition, uses ERNIE for entity relation extraction, and stores the extracted triples in Neo4j graph database. On this basis, an intelligent question answering system based on mine hoist fault knowledge graph is realized. This knowledge graph can reveal the complex correlation between mine hoist faults, realize the root cause analysis of related faults, and provide support for mine hoist fault diagnosis.
