摘要:

情感分类和讽刺检测都是自然语言处理的重要任务。在表达强烈情感的地方,感伤总是伴随着讽刺。然而,大多数文献认为它们是两个独立的任务。我们认为,讽刺检测的知识也可以有利于情感分类,反之亦然。我们证明了这两个任务是相关的,并使用深度神经网络提出了一个基于多任务学习的框架,该框架对这种相关性进行建模,以提高多任务学习环境中两个任务的性能。在基准数据集中,我们的方法比最新技术的性能高出3-4%。

英文摘要:

Sentiment classification and sarcasm detection are both important natural language processing (NLP) tasks. Sentiment is always coupled with sarcasm where intensive emotion is expressed. Nevertheless, most literature considers them as two separate tasks. We argue that knowledge in sarcasm detection can also be beneficial to sentiment classification and vice versa. We show that these two tasks are correlated, and present a multi-task learning-based framework using a deep neural network that models this correlation to improve the performance of both tasks in a multi-task learning setting. Our method outperforms the state of the art by 3-4% in the benchmark dataset.
