Papers with network-based question answering model
Exploiting WordNet Synset and Hypernym Representations for Answer Selection (2020.aacl-main)
Copied to clipboard
| Challenge: | Answer selection (AS) is a challenging subtask of document-based question answering (DQA). |
| Approach: | They propose to use WordNet to enrich the word representation and sentence encoding to incorporate similarity scores of two concepts that share synset or hypernym relations into the attention mechanism. |
| Outcome: | The proposed model outperforms existing state-of-the-art models on the public WikiQA and SelQA datasets and significantly improves the baseline system. |
