“结构化情感分析旨在从文本中抽取所有由情感持有者、目标事物、观点表示和情感极性构成的情感元组,是较为全面的细粒度情感分析任务。针对目前结构化情感分析方法错误传递,提示模版适应性不足和情感要素构成复杂的问题,本文提出了基于动态提示学习和依存关系的生成式结构化情感分析模型,根据不同的情感元组构成情况分别设计提示模版,并用模板增强生成式预训练模型的输入,用依存关系增强生成效果。实验结果显示,本文提出的模型在SemEval20221数据集上的SF1值优于所对比的基线模型。”

大语言模型在中文文本纠错任务的评测(Evaluation of large language models for Chinese text error correction tasks)
Lingling Mu (穆玲玲) | Xiaoying Wang (王晓盈) | Jiajia Cui (崔佳佳)
Proceedings of the 23rd Chinese National Conference on Computational Linguistics (Volume 1: Main Conference)

“大语言模型(Large Language Models,LLMs)在信息抽取、机器翻译等自然语言处理任务上的能力已被广泛评估,但是在文本纠错方面还主要局限于评价GPT的英文语法纠错能力 。中文文本纠错任务包括中文语法检测 (Chinese Grammatical Error Detection,CGED)和中文语法纠错(Chinese Error Correction,CGEC)两个子任务。本文使用提示的方法评估了国内外的主流大模型在中文语法检测和中文语法纠错任务上的能力。论文设计了不同的提示策略,对结果进行了整体和细粒度的分析。在NLPCC2018和CGED2018测试集上的实验结果表明,ERNIE-4和ChatGLM-4的中文文本纠错能力优于GPT-3.5-Turbo和LLaMa-2-7B-Chat,少样本思维链提示策略性能最优,对词序错误和拼写错误上纠正的准确率较高,说明大模型在低资源下具有较好的中文文本纠错能力。然而测试结果显示大模型的召回率比基线模型高至少14个百分点,说明大模型在中文文本纠错任务上存在过度校正的问题。”
