This paper shows that inference rules with temporal constraints can be acquired by us- ing verb-verb co-occurrences in Japanese coordinated sentences and verb-noun co- occurrences. For example, our unsuper- vised acquisition method could obtain the inference rule �If someone enforces a law, usually someone enacts the law at the same time as or before the enforcing of the law� since the verbs �enact� and �enforce� frequently co-occurred in coordinated sen- tences and the verbs also frequently co- occurred with the noun �law�. We also show that the accuracy of the acquisition is improved by using the occurrence fre- quency of a single verb, which we assume indicates how generic the meaning of the verb is.
