摘要
本文以文献[2]中信息抽取模型(InfoX)的测试语料(职务变动文本)为主要对象,具体说明怎样建立从动词的论元结构到相关的事件模板的匹配关系。首先根据职务变更动词的有关句法、语义特点,把它分成六个小类:任命、担任、免职、辞职、调遣、受命;然后,分别描写每一小类动词的论元结构,特别是它们所支配的论元角色及其句法配置方式。最后,建立动词的论元角色跟事件模板元素的匹配关系,并揭示动词对文本筛选和合并都有导向作用,说明发展由动词驱动的信息抽取方法的可行性。
This paper demonstrates how to estabhsh the matching relation between event-template of an information extraction （briefly, IE） system and the argument structure of the related verbs basing on the analysis of the succession texts according to [2] testing data for his IE system 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 argtunents and their syntactic arrangement. Finally, it establishes the matching relation between succession event-template elements and the argument roles of these six classes of succession verbs, reveals 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.
