Reasoning Over Semantic-Level Graph for Fact Checking
Table 2: Ablation study on develop set.
['Model', 'Label Accuracy']
Removing the graph-based distance drops 0.81% in terms of label accuracy. The graph-based distance mechanism can shorten the distance of two closely-linked nodes and help the model to learn their dependency. Removing the graph-based reasoning module drops 2.04% because graph reasoning module captures the structural information and performs deep reasoning about that.
