摘要:

远程监督模型在关系抽取中非常流行,因为我们可以使用远程监督方法获得大量的训练数据,而无需人工注释。在远程监督中,如果句子包含元组的两个实体,则该句子被认为是元组的源。然而,这个条件过于宽松,不能保证句子中存在相关的关系特定信息。因此,远程监督的训练数据包含大量噪声,这对模型的性能产生不利影响。在本文中,我们提出了一种自集成过滤机制,以过滤掉噪声样本在训练过程中。我们评估我们提出的框架上的纽约时报数据集,这是通过远程监督。我们的实验与多个国家的最先进的神经关系抽取模型表明,我们提出的过滤机制提高了模型的鲁棒性,并增加其F1分数。

英文摘要:

Distantly supervised models are very popular for relation extraction since we can obtain a large amount of training data using the distant supervision method without human annotation. In distant supervision, a sentence is considered as a source of a tuple if the sentence contains both entities of the tuple. However, this condition is too permissive and does not guarantee the presence of relevant relation-specific information in the sentence. As such, distantly supervised training data contains much noise which adversely affects the performance of the models. In this paper, we propose a self-ensemble filtering mechanism to filter out the noisy samples during the training process. We evaluate our proposed framework on the New York Times dataset which is obtained via distant supervision. Our experiments with multiple state-of-the-art neural relation extraction models show that our proposed filtering mechanism improves the robustness of the models and increases their F1 scores.
