Event, as a larger knowledge unit than "concept", is more consistent with human understanding process. Treating event as the core knowledge unit in news texts and applying the Neo-Davidsonian event semantic and 6-tuple event model theory, this paper proposes a new strategy for event representation. It is suggested that by extending some operators the action, object, tense and environment of the event and all the other fuzzy information modifying the event become known. And with the employment of the description logic method, the features of the news object in the event and event relations are represented effectively. The given instances indicate that this approach is good and effective for representing events and event relations in news texts.
Key words： Neo-Davidsonian; event; event relation; event representation
