This article addresses the causal structure of events described by verbs: whether an event happens spontaneously or it is caused by an external causer. We automat- ically estimate the likelihood of external causation of events based on the distribu- tion of causative and anticausative uses of verbs in the causative alternation. We train a Bayesian model and test it on a monolin- gual and on a bilingual input. The perfor- mance is evaluated against an independent scale of likelihood of external causation based on typological data. The accuracy of a two-way classification is 85% in both monolingual and bilingual setting. On the task of a three-way classification, the score is 61% in the monolingual setting and 69% in the bilingual setting.
