| 中文简介: | 列属性注释(CPA),也称为列关系预测,是在给定一组候选关系的情况下预测表中两列之间的语义关系的任务。CPA注释用于下游任务,如数据搜索、数据集成或知识图丰富。本文探讨了生成性大型语言模型(LLMs)在CPA任务中的使用。我们对CPA任务的不同零样本提示进行了实验,我们使用GPT-3.5、GPT-4和开源模型SOLAR对其进行了评估。我们发现GPT-3.5对提示的变化非常敏感,而GPT-4的性能与提示的变化无关。我们进一步探讨了CPA任务的训练数据可用的情况,这些数据可用于选择演示或微调模型。我们发现,在F1中,经过微调的GPT-3.5模型的表现优于在相同数据上微调了11%的RoBERTa模型。通过演示和微调进行的上下文学习比较表明,微调后的GPT-3.5比给定演示的相同模型表现出9%的F1性能。对于经过微调的数据集,经过微调的GPT-3.5模型的性能也优于零样本GPT-4约2%F1,同时不适用于需要不同词汇表的任务 |
| 课程简介: | Column property annotation (CPA), also known as column relationship prediction, is the task of predicting the semantic relationship between two columns in a table given a set of candidate relationships. CPA annotations are used in downstream tasks such as data search, data integration, or knowledge graph enrichment. This paper explores the usage of generative large language models (LLMs) for the CPA task. We experiment with different zero-shot prompts for the CPA task which we evaluate using GPT-3.5, GPT-4, and the open-source model SOLAR. We find GPT-3.5 to be quite sensitive to variations of the prompt, while GPT-4 reaches a high performance independent of the variation of the prompt. We further explore the scenario where training data for the CPA task is available and can be used for selecting demonstrations or finetuning the model. We show that a fine-tuned GPT-3.5 model outperforms a RoBERTa model that was fine-tuned on the same data by 11% in F1. Comparing in-context learning via demonstrations and fine-tuning shows that the fine-tuned GPT-3.5 performs 9% F1 better than the same model given demonstrations. The fine-tuned GPT-3.5 model also outperforms zero-shot GPT-4 by around 2% F1 for the dataset on which is was finetuned, while not generalizing to tasks that require a different vocabulary |
