Given this setup, if the opinion-argument classifier is highly confident that an Is about relation exists between two candidate entities, then these two entities will likely be extracted as an opinion and a target even if the entity extraction component fails to extract them or the target-implicit classifier erroneously determines that the opinion candidate is target-implicit.
the final entity extraction decisions and relation extraction decisions will be made jointly by the entity extraction model, the argument-implicit classifiers, and the opinion-argument classifiers by considering the confidence values they individually assign to the extraction decisions.
