| 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. |

| 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. |
