ABSTRACT
Novel coronavirus disease 2019 (COVID-19) is an ongoing health emergency. Several studies are related to COVID-19. However, its molecular mechanism remains unclear. The rapid publication of COVID-19 provides a new way to elucidate its mechanism through computational methods. This paper proposes a prediction method for mining genotype information related to COVID-19 from the perspective of molecular mechanisms based on machine learning. The method obtains seed genes based on prior knowledge. Candidate genes are mined from biomedical literature. The candidate genes are scored by machine learning based on the similarities measured between the seed and candidate genes. Furthermore, the results of the scores are used to perform functional enrichment analyses, including KEGG, interaction network, and Gene Ontology, for exploring the molecular mechanism of COVID-19. Experimental results show that the method is promising for mining genotype information to explore the molecular mechanism related to COVID-19.
