Abstract(in English) Addressing the task of acquiring semantic relations between events from a large corpus, we first argue the complementarity between the pattern-based relation-oriented approach and the anchor-based argument-oriented approach. We then proposes a two-phased approach, which first uses lexico-syntactic patterns to acquire predicate pairs and then uses two types of anchors to identify shared arguments. The present results of our empirical evaluation on a large-scale Japanese Web corpus have shown that (a) the anchor-based filtering extensively improves the precision of predicate pair acquisition, (b) the two types anchors are almost equally contributive and combining them improves recall without losing precision, and (c) the anchor-based method achieves high precision also in shared argument identification.
