Drug-drug interactions are frequently reported in the increasing amount of biomedical literature. Information Extraction (IE) techniques have been devised as a useful instrument to manage this knowledge. Nevertheless, IE at the sentence level has a limited effect
because of the frequent references to previous entities in the discourse, a phenomenon
known as 'anaphora'. DrugNerAR, a drug anaphora resolution system is presented to
address the problem of co-referring expressions in pharmacological literature. This
development is part of a larger and innovative study about automatic drug-drug interaction
extraction.
