Questions about exploit the entities in captions

[davidluciolu]

Hi! I read in Section3.1 of your paper that

Specifically, we first obtain the “synonymy label” in WordNet2 of each noun in groundtruth captions. And then, we choose nouns with labels “object.n.01”, “causal agent.n.01”, and “matter.n.03” as entities, discarding abstract nouns

Could you please can provide some code to explain how to exploit the entities in captions?
