基于语法丰富性的汉语二语写作质量分析研究

Analysis of CSL writing quality based on grammatical richness

为了更好地对二语写作中的语法产出质量进行分析,本文提出了一种新的评估指标:语法丰富性,该指标包含了语法多样性、语法复杂性以及语法正确性三个维度。我们对每个维度设计了相应的测量工具,并基于HSK动态作文语料库对语法丰富性与写作质量之间的关系进行了实证研究。研究发现,语法丰富性的三个维度对写作质量均有显著影响,其中语法多样性对从低分段到中分段的变化有较大影响,而语法复杂性和语法正确性则在全分段的变化中都产生了显著的影响。另外,语法丰富性可以作为一种关键特征与词汇丰富性等其他特征进行融合,从而对写作质量进行更加全面和准确的评价。

In this paper we propose a new grammatical quality assessment index:grammatical richness,which includes three dimensions:grammatical diversity,grammatical complexity and grammatical correctness.We design corresponding measurement tools for each dimension and conduct an empirical study on the relationship between grammatical richness and writing quality on HSK dynamic corpus.It is found that the three dimensions of grammatical richness have a significant impact on the writing quality.Among them,grammatical diversity has a great impact on the change from low-score group to middle-score group,while grammatical complexity and grammatical correctness have a significant impact on all groups.In addition,grammatical richness feature can be integrated with other features such as lexical richness to make a more comprehensive and accurate evaluation on CSL writing quality.
