MetaQA: Combining Expert Agents for Multi-Skill Question Answering (2023.eacl-main)
Copied to clipboard
| Challenge: | Recent explosion of question-answering datasets and models has increased interest in generalization of models across multiple domains and formats. |
| Approach: | They propose to combine expert agents with a flexible and training-efficient architecture that considers questions, answer predictions, and answer-prediction confidence scores to select the best answer among a list of answer predictions. |
| Outcome: | The proposed model outperforms previous multi-agent and multi-dataset approaches and is highly data-efficient to train and adaptable to any QA format. |

| Challenge: | Recent advances in NLP and information retrieval have given rise to a diverse set of question answering tasks that are of different formats and require different model architectures and setups. |
| Approach: | They propose an extensible online QA platform that allows users to query and analyze a large collection of modern Skills via a user-friendly web interface and integrated behavioural tests. |
| Outcome: | The proposed tool allows users to query and analyze a large collection of modern Skills via a user-friendly web interface and integrated behavioural tests. |

| Challenge: | Annotations are expensive and difficult to obtain, which is why many NLP systems outsource their work to paid crowdworkers. |
| Approach: | They propose to use Citizen Science to re-annotate parts of a pre-existing crowdsourced dataset to gain high-quality annotations. |
| Outcome: | The proposed approach yields high-quality annotations and motivated volunteers, but requires consideration of scalability, participation over time, and legal and ethical issues. |
