摘要:

细粒度实体类型标注(FET)是自然语言处理中的一项重要任务,旨在为文本中的实体分配语义类型。然而,FET面临一个被称为噪声标注问题的主要挑战,当前方法依赖估计噪声分布来识别噪声标签,但会受到多种噪声分布偏差的干扰。为了解决这一局限性,我们引入了Co-Prediction Prompt Tuning用于FET中的噪声纠正,该方法利用多个预测结果来识别和纠正噪声标签。具体而言,我们整合预测结果以召回已标注的标签,并利用差异化边际来识别不准确的标签。此外,我们在微调期间设计了一个关于分歧协同预测的优化目标,确保模型捕获充足的信息并在噪声识别中保持鲁棒性。在三个广泛使用的FET数据集上的实验结果表明,我们的噪声纠正方法显著提升了各类训练样本的质量,包括使用远程监督、ChatGPT和众包标注的样本。

英文摘要:

Fine-grained entity typing (FET) is an essential task in natural language processing that aims to assign semantic types to entities in text. However, FET poses a major challenge known as the noise labeling problem, whereby current methods rely on estimating noise distribution to identify noisy labels but are confused by diverse noise distribution deviation. To address this limitation, we introduce Co-Prediction Prompt Tuning for noise correction in FET, which leverages multiple prediction results to identify and correct noisy labels. Specifically, we integrate prediction results to recall labeled labels and utilize a differentiated margin to identify inaccurate labels. Moreover, we design an optimization objective concerning divergent co-predictions during fine-tuning, ensuring that the model captures sufficient information and maintains robustness in noise identification. Experimental results on three widely-used FET datasets demonstrate that our noise correction approach significantly enhances the quality of various types of training samples, including those annotated using distant supervision, ChatGPT, and crowdsourcing.
