We implemented and evaluated two argument identification enhancements to SemRep, a biomedical semantic relation extraction tool. A precision-focused rule uses lexical information and prepositional phrase attachment heuristics to address prepositionally-triggered relations, and a recall-focused rule restricts argument scope for relations triggered by hyphenated adjectives. Both rules improved precision, while the first led to some recall loss. Their overall effect for downstream applications is considered positive.
