摘要:

讽刺使用矛盾心理,一个人说一些积极的事情,但实际上意味着消极,反之亦然。讽刺的实质是一句话中所表达的字面意思和隐含意思的冲突,这也是讽刺的充分必要条件。然而,这种情感冲突很难识别,因为情感是混合的,甚至是隐含的。因此,对复杂、模糊情感的识别给讽刺检测带来了巨大的挑战。在本文中,我们提出了一个双通道框架,分别建模字面和隐含的情绪。在此双通道框架的基础上,我们设计了双通道网络DC-Net来识别情感冲突。在政治辩论(即IAC-V1和IAC-V2)和Twitter数据集上的实验表明,我们提出的DC-Net在讽刺识别方面达到了最先进的性能。我们的代码被发布以支持研究。

英文摘要:

Sarcasm employs ambivalence, where one says something positive but actually means negative, and vice versa. The essence of sarcasm, which is also a sufficient and necessary condition, is the conflict between literal and implied sentiments expressed in one sentence. However, it is difficult to recognize such sentiment conflict because the sentiments are mixed or even implicit. As a result, the recognition of sophisticated and obscure sentiment brings in a great challenge to sarcasm detection. In this paper, we propose a Dual-Channel Framework by modeling both literal and implied sentiments separately. Based on this dual-channel framework, we design the Dual-Channel Network~(DC-Net) to recognize sentiment conflict. Experiments on political debates (i.e. IAC-V1 and IAC-V2) and Twitter datasets show that our proposed DC-Net achieves state-of-the-art performance on sarcasm recognition. Our code is released to support research.
