A temporal knowledge graph (TKG) comprises facts aligned with timestamps. Question answering over TKGs (TKGQA) finds an entity or timestamp to answer a question with certain temporal constraints. Current studies assume that the questions are fully annotated before being fed into the system, and ...
The first step computes question-relevant compact subgraphs within the knowledge graph that contain all cues required for answering the question, using Group Steiner Trees and fine-tuned BERT models, and judiciously enhances them with pertinent temporal facts.(第一步使用 Group Steiner Trees 和微调的 ...
