Simple Question Answering with Subgraph Ranking and Joint-Scoring (N19-1)
Copied to clipboard
| Challenge: | Knowledge graph based simple question answering is a major area of research in question answering. |
| Approach: | They propose a framework to describe and analyze existing knowledge graph based simple question answering approaches. |
| Outcome: | The proposed model achieves a state-of-the-art (85.44% accuracy) on the SimpleQuestions dataset. |
FaiRR: Faithful and Robust Deductive Reasoning over Natural Language (2022.acl-long)
Copied to clipboard
| Challenge: | Currently, black-box models generate both the proof graph and intermediate inferences within the same model and thus may be unfaithful. |
| Approach: | They propose a transformer-based model that can perform deductive reasoning on a logical rulebase containing rules and statements written in natural language. |
| Outcome: | The proposed model is robust to language perturbations and faster at inference than previous models on existing reasoning datasets. |
FRVA: Fact-Retrieval and Verification Augmented Entailment Tree Generation for Explainable Question Answering (2024.findings-acl)
Copied to clipboard
| Challenge: | Existing methods for generating a entailment tree exhibit the reasoning chains from knowledge facts to predicted answers, but they have large fact search spaces and error accumulation problems resulting in the generation of invalid steps. |
| Approach: | They propose a Fact-Retrieval and Verification Augmented bidirectional entailment tree generation method that contains two systems. |
| Outcome: | The proposed method outperforms existing models and achieves state-of-the-art performance in fact selection and structural correctness. |
