Fig. 3From: Leveraging syntactic and semantic graph kernels to extract pharmacokinetic drug drug interactions from biomedical literatureIllustration of multi linguistic level graph representation. The candidate interaction pair is marked as “drug1” and “drug2”. The shortest path between the drugs is shown in bold. In the dependency (a), predicate-argument structure (b), and an integration of semantic class with dependency (d) based subgraphs all nodes in the shortest path are specialized using a post-tag (IP). In the linear order subgraph (d) possible tags are (B)efore, (M)iddle, and (A)fterBack to article page
