Hypergraph embedding-based representation method for multi-nary relational knowledge of bridge crane faults
The conventional knowledge graph can only deal with binary relations,while knowledge of bridge crane faults contains a large number of multi-nary relations of"multiple phenomena,multiple causes,and multiple methods".If forced to transform,the integrity of the relations will be destroyed,causing serious information distortion.To deal with such complex multi-nary relational knowledge to ensure integrity,the Knowledge hypergraph was proposed and a hypergraph embedding-based representation method for multi-nary relational knowledge of bridge crane faults was designed.Through sorting the correlation among phenomena,causes,methods and other data in the driving fault sheet,a driving fault ontolo-gy model suitable for characterizing the multi-nary relation was constructed,which was taken as the schema for establishing the knowledge hypergraph of bridge crane faults.Based on the BERT model in natural language processing and the hyperg-raph convolutional network,the embedding representation of fault knowledge was obtained,hence similar fault retrieval could be carried out.By exploiting the fault sheets of bridge cranes collected from a steel factory,the effectiveness of the proposed method was verified.
