This paper demonstrates how to establish the ma tc hing relation between event-template of an information extraction (briefly, IE) system and the argument structure of the related verbs basing on the analysis o f the succession texts according to [2] testing data for his IE sys te m InfoX. It firstly divides the succession verbs into six classes (appoint, hold , remove, resign, dispatch, transfer) according to their syntactic and semantic features. Then it describes the argument structure of these six classes of verbs , especially the thematic role of the arguments and their syntactic arrangement. Finally, it establishes the matching relation between succession event-templat e elements and the argument roles of these six classes of succession verbs, revea ls the orientation function of the related verbs in screen and merger of texts, and illustrates the possibility of developing a verb-driven approach of IE.
