摘　　要：动词子语类框架(Subcategorization Frame以下简称SCF)在句法分析、语义角色标注等方面的研究中具有不可或缺的重要作用。在子语类框架信息的获取过程中,首先要建立标准完备的子语类框架类型集。目前英语研究已经建立了获得普遍共识的子语类框架类型集。而汉语方面还没有标准的动词子类框架类型集。本文提出一种语言学知识与统计方法相结合的汉语动词子语类框架类型集的半自动获取方案。初步建立起既符合统计结果又基本符合语言学理论的汉语动词子语类框架类型集。实验证明,加入语言学理论的子语类框架类型集降低了对语料的依赖程度,比完全由分析语料产生的类型集更完备。Subcategorization of verbs is an essential issue and plays an important role in syntactic parsing, semantic roles labeling and etc. A sufficient subcategorization frame type set is critical for subcategorization acquisition. By now, a set of subcategorization frame types has come to an agreement in English, while no standard subcategorization frame type set for Chinese verbs has been achieved. In this paper we apply a semi-supervise method for subcategorization frame type acquisition with linguistic theory and statistical algorithm. Firstly we create a set of seeds of subcategorization patterns according to linguistics theory. And then a semi-supervise machine learning method is applied to analyze the corpus for extending the seeds. Contrasted with a corpus based subcategorization frame type acquisition mehtod, our method gains better precision and coverage.
