三元搭配视角下的汉语动词语义角色知识库构建

动词语义角色一直是国内外语言学界研究的重点和难点。在自然语言处理领域,相关的语言资源也在逐步构建。对于汉语而言,国内大部分工作集中在语义角色标注上。该文创造性地提出了一种三元搭配的动词语义角色知识表征形式,并在前人研究的基础上,提出了一套语义角色分类体系。在该体系指导下,对汉语动词进行了穷尽式的语义角色认定及相关知识加工,以构建汉语动词语义角色知识库。截至目前,该工程考察了5 260个动词,加工了语义角色及引导词的动词数量为2 685个,加工认定语义角色4 307个。

Construction of Semantic Role Bank for Chinese Verbs from the Perspective of Ternary Collocation

The research on semantic roles has always been a significant challenge in the field of linguistics. Some resources on the semantic relations have been constructed; however, most of the domestic researches on Chinese word semantic relations focuses on the labeling. This paper proposes a novel structure, the ternary collocation, to describe the semantic relations with verbs at the core. The paper also puts forward a semantic role classification scheme, under which a semantic role bank for Chinese verbs is constructed. All the verbs involved are exhaustively identified for the possible semantic roles and other related knowledge annotation. Altogether 5,260 verbs are collected, among which 2,685 verbs are assigned with 4,307 semantic roles as well as the guiding word.
