Before revision:  In this paper, we present our ongoing work on SciSight, a novel framework for exploratory search of COVID-19 research . Based on formative interviews with scientists and a review of existing tools, we build and integrate two key capabilities: first, exploring interactions between biomedical facets  (e.g., proteins, genes, drugs, diseases, patient characteristics);
After revision:  In this paper, we present our ongoing work on SciSight, a novel framework for exploratory search of COVID-19 research . Based on formative interviews with scientists and a review of existing tools, we build and integrate two key capabilities: first, exploring interactions between biomedical facets automatically extracted from papers (e.g., proteins, genes, drugs, diseases, patient characteristics);
