However, no significant performance gain could be observed in both experiments Based on our analysis, we conclude that heterogeneous data and FGE from unreliable sources, as found in our corpus and in the real world, make it difficult to correctly classify the claims.
in future experiments, not just FGE need to be taken into account, but also additional information from our newly constructed corpus, that is, the stance of the FGE, FGE sources, and documents from the Snopes website which provide additional information about the claim.
