Simple yet Effective Bridge Reasoning for Open-Domain Multi-Hop Question Answering (D19-58)
Copied to clipboard
| Challenge: | Existing work on open-domain multi-hop question answering relies on off-the-shelf information retrieval techniques to retrieve answer passages. |
| Approach: | They propose a new subproblem for open-domain multi-hop question answering . they aim to recognize the anchor from a set of start passages with a reading comprehension model . |
| Outcome: | The proposed method significantly improves the baseline method on the open-domain hotpotQA benchmark. |
Neural Models for Reasoning over Multiple Mentions Using Coreference (N18-2)
Copied to clipboard
| Challenge: | Existing Recurrent Neural Network (RNN) layers are biased towards short-term dependencies and hence not suited to such tasks. |
| Approach: | They propose a recurrent layer which is instead biased towards coreferent dependencies and uses coreference annotations extracted from an external system to connect entity mentions belonging to the same cluster. |
| Outcome: | The proposed layer improves performance on Wikihop, LAMBADA and the bAbi AI datasets with large gains when training data is scarce. |
The Web as a Knowledge-Base for Answering Complex Questions (N18-1)
Copied to clipboard
| Challenge: | Recent work on reading comprehension made headway in answering simple questions, but tackling complex questions is still an ongoing research challenge. |
| Approach: | They propose to decompose complex questions into a sequence of simple questions and compute the final answer from the sequence of answers. |
| Outcome: | The proposed framework improves performance from 20.8 precision@1 to 27.5 precision@1. |
