Problems Identified (5)
Incomplete electrical equipment knowledge graph: Knowledge graphs for electrical equipment are incomplete and need further mining to improve graph integrity.
Complex relation modeling limitation: Existing TransE-style knowledge graph embedding is limited because it is only suitable for one-to-one relations and struggles with complex entity relations.
Out-of-graph entity completion: Knowledge graph completion must support representation and completion of out-of-graph entities in power transformer maintenance triples.
