汉语学习者依存句法树库构建(Construction of a Treebank of Learner Chinese)
汉语学习者依存句法树库为非母语者语料提供依存句法分析, 可以支持第二语言教学与研究, 也对面向第二语言的句法分析、语法改错等相关研究具有重要意义。然而, 现有的汉语学习者依存句法树库数量较少, 且在标注方面仍存在一些问题。为此, 本文改进依存句法标注规范, 搭建在线标注平台, 并开展汉语学习者依存句法标注。本文重点介绍了数据选取、标注流程等问题, 并对标注结果进行质量分析, 探索二语偏误对标注质量与句法分析的影响。
Overview of NLPTEA-2020 Shared Task for Chinese Grammatical Error Diagnosis
This paper presents the NLPTEA 2020 shared task for Chinese Grammatical Error Diagnosis (CGED) which seeks to identify grammatical error types, their range of occurrence and recommended corrections within sentences written by learners of Chinese as a foreign language.
汉语增强依存句法自动转换研究(Transformation of Enhanced Dependencies in Chinese)
“自动句法分析是自然语言处理中的一项核心任务, 受限于依存句法中每个节点只能有一条入弧的规则, 基础依存句法中许多实词之间的关系无法用依存弧和依存标签直接标明;同时, 已有的依存句法体系中的依存关系还有进一步细化、提升的空间, 以便从中提取连贯的语义关系。面对这种情况, 本文在斯坦福基础依存句法规范的基础上, 研制了汉语增强依存句法规范, 主要贡献在于:介词和连词的增强、并列项的传播、句式转换和特殊句式的增强。此外, 本文提供了基于Python的汉语增强依存句法转换的转换器, 以及一个基于Web的演示, 该演示将句子从基础依存句法树通过本文的规范解析成依存图。最后, 本文探索了增强依存句法的实际应用, 并以搭配抽取和信息抽取为例进行相关讨论。”
面向汉语作为第二语言学习的个性化语法纠错(Personalizing Grammatical Error Correction for Chinese as a Second Language)
语法纠错任务旨在通过自然语言处理技术自动检测并纠正文本中的语序、拼写等语法错误。当前许多针对汉语的语法纠错方法已取得较好的效果, 但往往忽略了学习者的个性化特征, 如二语等级、母语背景等。因此, 本文面向汉语作为第二语言的学习者, 提出个性化语法纠错, 对不同特征的学习者所犯的错误分别进行纠正, 并构建了不同领域汉语学习者的数据集进行实验。实验结果表明, 将语法纠错模型适应到学习者的各个领域后, 性能得到明显提升。
基于BERT与柱搜索的中文释义生成(Chinese Definition Modeling Based on BERT and Beam Seach)
释义生成任务是指为一个目标词生成相应的释义。前人研究中文释义生成任务时未考虑目标词的上下文, 本文首次在中文释义生成任务中使用了目标词的上下文信息, 并提出了一个基于BERT与柱搜索的释义生成模型。本文构建了包含上下文的CWN中文数据集用于开展实验, 除了BLEU指标之外, 还使用语义相似度作为额外的自动评价指标, 实验结果显示本文模型在中文CWN数据集和英文Oxford数据集上均有显著提升, 人工评价结果也与自动评价结果一致。最后, 本文对生成实例进行了深入分析。
句式结构树库的自动构建研究(Automatic Construction of Sentence Pattern Structure Treebank)
“句式结构树库是以句本位语法为理论基础构建的句法资源, 对汉语教学以及句式结构自动句法分析等研究具有重要意义。目前已有的句式结构树库语料主要来源于教材领域, 其他领域的标注数据较为缺乏, 如何高效地扩充高质量的句法树库是值得研究的问题。人工标注句法树库费时费力, 并且树库质量也难以保证, 为此, 本文尝试通过规则的方法, 将宾州中文树库(ctb)转换为句式结构树库, 从而扩大现有句式结构树库的规模。实验结果表明, 本文提出的基于树库转换规则的方法是有效的。”
中美学者学术英语写作中词汇难度特征比较研究——以计算语言学领域论文为例(A Comparative Study of the Features of Lexical Sophistication in Academic English Writing by Chinese and American)
“学术英语写作在国际学术交流中的作用日益凸显, 然而对于英语非母语者, 学术英语写作是困难的, 为此本文对计算语言领域中美学者学术英语写作中词汇难度特征做比较研究。自构建1132篇中美论文全文语料库, 统计语料中484个词汇难度特征值。经过特征筛选与因子分析的降维处理得到表现较好的五个维度。最后计算中美学者论文的维度分从而比较差异, 发现美国学者的论文相较中国学者的论文中词汇单位更具常用性、二元词串更具稳固性、三元词串更具稳固性、虚词更具复杂性、词类更具关联性。主要原因在于统计特征值时借助的外部资源库与美国学者的论文更贴近, 且中国学者没有完全掌握该领域学术写作的习惯。因此, 中国学者可充分利用英语本族语者构建的资源库, 从而产出更为地道与流利的学术英语论文。”
Cross-domain Chinese Sentence Pattern Parsing
Sentence Pattern Structure (SPS) parsing is a syntactic analysis method primarily employed in language teaching. Existing SPS parsers rely heavily on textbook corpora for training, lacking cross-domain capability. To overcome this constraint, this paper proposes an innovative approach leveraging large language models (LLMs) within a self-training framework.
OMGEval: An Open Multilingual Generative Evaluation Benchmark for Large Language Models
We evaluate several representative multilingual LLMs on the proposed OMGEval, which we believe will provide a valuable reference for the community to further understand and improve the multilingual capability of LLMs.
