AI总结:

本研究系统评估了在讽刺识别中增加多种上下文线索的效果,开发了集成框架,在三个基准上达到最先进性能,并揭示了更多上下文可能引入社会偏见的固有缺点。

摘要:

讽刺识别具有挑战性,因为它需要理解与词语字面意思相反或不同的真实意图。先前的工作通过开发一系列为模型提供更丰富上下文(如情感或文化细微差别)的方法来解决这一挑战。虽然这些方法单独使用时被证明有效,但没有研究系统地评估它们的集体有效性。因此,额外上下文能在多大程度上改进讽刺识别仍不清楚。在这项工作中,我们通过将更多上下文融入模型来探索现有方法带来的改进。为此,我们开发了一个框架,可以在其中集成多种上下文线索并测试不同的方法。在三个讽刺识别基准上使用四种方法进行评估时,我们达到了现有的最先进性能,并展示了依次添加更多上下文的好处。我们还发现了使用更多上下文的固有缺点,强调在追求更好结果的过程中,模型可能需要采纳社会偏见。

英文摘要:

Sarcasm recognition is challenging because it needs an understanding of the true intention, which is opposite to or different from the literal meaning of the words. Prior work has addressed this challenge by developing a series of methods that provide richer $contexts$, e.g., sentiment or cultural nuances, to models. While shown to be effective individually, no study has systematically evaluated their collective effectiveness. As a result, it remains unclear to what extent additional contexts can improve sarcasm recognition. In this work, we explore the improvements that existing methods bring by incorporating more contexts into a model. To this end, we develop a framework where we can integrate multiple contextual cues and test different approaches. In evaluation with four approaches on three sarcasm recognition benchmarks, we achieve existing state-of-the-art performances and also demonstrate the benefits of sequentially adding more contexts. We also identify inherent drawbacks of using more contexts, highlighting that in the pursuit of even better results, the model may need to adopt societal biases.
