Adaptive Information Seeking for Open-Domain Question Answering (2021.emnlp-main)
Copied to clipboard
| Challenge: | Existing iterative approaches to open-domain question answering use predefined strategies . e.g., BM25, DPR, and hyperlink are defined as actions . |
| Approach: | They propose a novel adaptive information-seeking strategy for open-domain question answering . they propose to use a partially observed Markov decision process to select a proper retrieval action . |
| Outcome: | Experiments on SQuAD Open and HotpotQA fullwiki show that AISO outperforms baseline methods with predefined strategies in retrieval and answer evaluations. |
