Overview of the proposed framework. The proposed method consists of 3 steps: (1) extraction of vaccine-related associations from Semantic MEDLINE using ontology-based terms; (2) network-based analyses to identify vaccine-vaccine associations and vaccine-gene associations; and (3) evaluation of inferred vaccine-vaccine and vaccine-gene relationships using VO hierarchical structure and literature validation.
