In this paper, we propose a method for creating automatically weighted lexicons of event names. Almost all names of events are ambiguous in context (i.e., they can be interpreted in an eventive or noneventive reading). Therefore, weights representing the relative eventiveness of a noun can help for disambiguating event detection in texts. We applied our method on both French and English corpora. Our method has been applied to both French and English corpora. We performed an evaluation based
