“空间语义理解任务致力于使语言模型能够准确解析和理解文本中描述的物体间的空间方位关系,这一能力对于深入理解自然语言并支持复杂的空间推理至关重要。本文聚焦于探索大模型的上下文学习策略在空间语义理解任务上的有效性,提出了一种基于选项相似度与空间语义理解能力相似度的样本选择策略。本文将上下文学习与高效微调融合对开源模型进行微调,以提高大模型的空间语义理解能力。此外,本文尝试结合开源模型和闭源模型的能力处理不同类型的样本。实验结果显示,本文所采用的策略有效地提高了大模型在空间语义理解任务上的性能。”

“Entity relation extraction, as a core task of information extraction, aims to predict the relation ofentity pairs identified by text, and its research results are applied to various fields. To addressthe problem that current distantly supervised relation extraction (DSRE) methods based on large-scale corpus annotation generate a large amount of noisy data, a DSRE method that incorporatesselective gate and noise correction framework is proposed. The selective gate is used to reason-ably select the sentence features in the sentence bag, while the noise correction is used to correctthe labels of small classes of samples that are misclassified into large classes during the modeltraining process, to reduce the negative impact of noisy data on relation extraction. The resultson the English datasets clearly demonstrate that our proposed method outperforms other base-line models. Moreover, the experimental results on the Chinese dataset indicate that our methodsurpasses other models, providing further evidence that our proposed method is both robust andeffective.”
