Fig. 1From: InfAcrOnt: calculating cross-ontology term similarities using information flow by a random walkSub-graph of the Directed Acyclic Graph of three GO sub-ontologies. Each node indicates a term of GO, and each arrow symbol represents an ‘IS_A’ relationship of GO. For example, “catalytic complex” is linked to “protein complex” by an ‘IS_A’ relationshipBack to article page
