Faithful Knowledge Graph Explanations in Commonsense Question Answering (2022.emnlp-main)
Copied to clipboard
| Challenge: | Knowledge graphs are used to express explanations for the model's answer choice. |
| Approach: | They propose to use knowledge graphs to encode facts separately from the question and combine them to select an answer. |
| Outcome: | The proposed architectures can be used to express the facts used to answer a question in a graph-based explanation, but they will not include reasoning done by the transformer encoding the question, and will be incomplete. |
