提出了一种新的基于词的日语依存句法分析器的设计方案,该方案集成了句法结构分析和语法功能分析,如谓元结构分析。与日语自然语言处理中主要使用的基于bunsetsu的依存关系分析相比,它提供了一种自然的提取句法成分的方法,这对于统计机器翻译等后续应用是有用的。它还使联合决定依赖关系和谓词论元结构成为可能,这通常是作为两个单独的步骤实现的。我们将现有的树库转换为新的依赖方案,并报告解析结果作为未来研究的基线。通过使用语法函数作为依存关系标签,我们获得了比谓词论元结构分析器更高的函数标签赋值精度。
We present a novel scheme for wordbased Japanese typed dependency parser which integrates syntactic structure analysis and grammatical function analysis such as predicate-argument structure analysis. Compared to bunsetsu-based dependency parsing, which is predominantly used in Japanese NLP, it provides a natural way of extracting syntactic constituents, which is useful for downstream applications such as statistical machine translation. It also makes it possible to jointly decide dependency and predicate-argument structure, which is usually implemented as two separate steps. We convert an existing treebank to the new dependency scheme and report parsing results as a baseline for future research. We achieved a better accuracy for assigning function labels than a predicate-argument structure analyzer by using grammatical functions as dependency label.
