英文摘要：
The basic work of narrative text information mining is to extract narrative texts＇ feature words and to represent narrative texts by using them. The existing representation models for texts are by means of vector space model or FCA technology, which proceeds from texts＇ feature words and organizes them reasonably to achieve the goal of text representation. However they are lacking of semantic comprehension for texts. Semantic features of narrative texts are focused on in this paper. It reveals the hierachical feathers of narrative texts that they contain a lot of events, and events are composed of event elements. Furthermore, a hierachical representation model for narrative texts based on FCA is proposed.
