For biomedical information extraction, most sys- tems use syntactic patterns on verbs (anchor verbs) and their arguments. Anchor verbs can be se- lected by focusing on their arguments. We propose to use predicate-argument structures (PASs), which are outputs of a full parser, to obtain verbs and their arguments. In this paper, we evaluated PAS method by comparing it to a method using part of speech (POSs) pattern matching. POS patterns produced larger results with incorrect arguments, and the re- sults will cause adverse effects on a phase selecting appropriate verbs.
