基于这些线索,在本文中,我们转向ChatGPT,并假设ChatGPT天生就有合适的能力,可以在互动模式下沉淀出一个统一的zero-shot程IE模型。更具体地说,我们提出了ChatIE,将zero-shotIE任务转化为具有two-stage框架的多轮提问-回答问题。在第一阶段,我们旨在找出句子中可能存在的相应元素类型。然后在第二阶段,我们对第一阶段的...
zero-shot information extraction 的目是从未注释的文本中构建信息提取(IE)系统,由于大模型发展迅速,其下游任务效果有了质的提升,文章中考虑采用prompt技巧进行信息提取,观察zero-shot 提取信息的可取性; 为此创建了一个二阶段的多回合问答框架ChatIE,并在三个IE任务上广泛地评估:整体关系三重提取、命名实体识别和事件...
在ZERO-SHOT背景下实现关系抽取 对于信息抽取中的关系抽取任务,想要在zero-shot背景下抽取到准确和正确的关系,个人从ChatIE文章中得到启发。 论文:Zero-Shot Information Extraction via Chatting with ChatGPT 方法:基于现有的gpt模型结合对比学习算法,进行搭建训练,再让模型过滤和判别出正确的关系三元组。 算法策略选择:...
Large language models achieve good performances on various downstream NLP tasks without parameter tuning, becoming a possible way to extract information in a zero-shot manner. Methods In this study, we aim to explore whether the most popular large language model, ChatGPT, can extract information ...

In this paper, we explore the zero-shot relation extraction to overcome the challenge. The only requisite information about an unseen type is the label name. We propose a Parasitic Neural Network (PNN), where unseen types are parasitic on seen types to get automatic annotation and training. ...
