Neural Unification for Logic Reasoning over Natural Language (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Automated Theorem Proving (ATP) is a computer program that can show that conjectures are logical consequences of a set of axioms. |
| Approach: | They propose a transformer-based architecture for deriving conjectures given axioms . they propose 'neural unifier' and relative training procedure to train the model . |
| Outcome: | The proposed architectures are able to answer queries with deep queries with a relatively low training time. |

Gabriele Picco, Marcos Martinez Galindo, Alberto Purpura, Leopold Fuchs, Vanessa Lopez, Thanh Lam Hoang
| Challenge: | ZSL is a machine learning field that uses textual descriptions of entities or relations to perform tasks that are not seen during training. |
| Approach: | They propose a framework that allows researchers to compare state-of-the-art ZSL methods with standard benchmark datasets. |
| Outcome: | The proposed framework compares state-of-the-art methods with benchmark datasets and provides APIs for production under the standard SpaCy NLP pipeline. |

Gabriele Picco, Leopold Fuchs, Marcos Martínez Galindo, Alberto Purpura, Vanessa López, Hoang Thanh Lam
| Challenge: | Named Entity Recognition and Relation Extraction (RE) methods are expensive and require domain experts for data acquisition and labeling. |
| Approach: | They propose a strategy for generating variations of an initial description, a heuristic for ranking them and an ensemble method capable of boosting the predictions of zero-shot models. |
| Outcome: | The proposed method outperforms existing approaches and achieves new SOTA results on four different entity and relation classification datasets. |
Maximum Bayes Smatch Ensemble Distillation for AMR Parsing (2022.naacl-main)
Copied to clipboard
| Challenge: | AMR parsing has experienced an unprecendented increase in performance in the last three years due to a mixture of effects including architecture improvements and transfer learning. |
| Approach: | They propose to combine Smatch-based ensembling techniques with ensemble distillation to overcome this diminishing returns of silver data. |
| Outcome: | The proposed technique can produce gains rivaling those of human annotated data for QALD-9 and achieve a new state-of-the-art for BioAMR. |
