【摘要】：中文命题库(the Chinese Proposition Bank)是在中文树库(the Chinese Treebank)上标注语义角色的语料库。语义角色是语言学研究的重要内容之一,标注了语义角色的命题库不但提供了谓语动词(predicate verb)的论元结构(argument structure),也提供了可谓词(predicative verb)语义角色的句法实现方式,大规模的"词汇语义-句法结构"语料为相关语言学研究提供了大量的真实数据。目前语义角色是以基于特定谓语动词(predicate-specific)的方式进行定义并使用统一的标记进行标注,这个标注方式导致了语义角色标记意义在不同的动词论元结构中的不一致问题,导致在语义上我们无法对动词的论元结构的句法实现做更深入的理解和解释。为了改进这个问题,本文定义了一套全局性语义角色标记并标注到命题库中。结果显示,标注了全局性语义角色的中文命题库解决了语义角色不一致的问题,丰富了动词论元结构模式,并且使得我们可以更好的从语义上理解动词论元的句法表现。本文的工作不是对之前标注工作的否定,而是增加一层标注以形成完整的语义资源,提供了关于论元的语义角色和句法实现之关系的大规模真实数据,使得我们可以更加全面深入的认识动词论元结构的问题。
[Abstract]:The Chinese Proposition Bank is in the Chinese Treebank. Semantic role is an important part of linguistic research. A propositional library that annotates semantic roles not only provides the argument structure of the predicate verb predicate]. It also provides the syntactic implementation of semantic roles, which can be described as "predictive verbative". The large-scale "lexical semantic-syntactic structure" corpus provides a large amount of real data for relevant linguistic research. At present, semantic roles are based on specific predicate verbs (. The predicate-specific approach is defined and annotated using uniform markup. This approach leads to the inconsistency of semantic role markers in different verb argument structures. In order to improve this problem, we can not understand and explain the syntactic implementation of the argument structure of verbs more deeply. In this paper, a set of global semantic role tags is defined and annotated into the propositional database. The results show that the Chinese propositional database with global semantic roles has solved the problem of semantic role inconsistency. It enriches the verb argument structure pattern and enables us to understand the syntactic representation of verb argument better semantically. The work of this paper is not to negate the previous annotation work. Instead, a layer of annotations is added to form a complete semantic resource, providing large-scale real data on the semantic role of argument and the relationship between syntactic implementation. So that we can fully understand the problem of verb argument structure.

【正文快照】： 1引言近年来,标注语义角色的语言资源受到研究者的重视,它对语言学本体研究和自然语言处理都很有价值。目前已经出现了一些有影响力的语义角色标注语料库,如Frame Net(Baker et al.1998),宾州命题库(Palmer M et al.2005)。大规模语义角色语料库的建立推动了自动语义角色标注
