Natural Language Inference (NLI) method
In this approach we use a BART classifier (Lewis et al., 2019) pre-trained on the Multi-Genre NLI (MultiNLI, Williams et al., 2018) corpus as the base model.
Given research interests expressed in natural language, we pose the problem of recovering relevant research from the CORD-19 dataset (Wang et al., 2020) as a Zero Shot Topic Classification task (Yin et al., 2019). Leveraging the Natural Language Inference task framework, we assess each paper relevance by feeding the model with the paper's title and abstract as premise and a research interest as hypothesis.
Finally, we use the model's entailment inference values as proxy relevance scores for each paper.
