论文摘要
给定特定的话语，哪种话语属性会触发使用隐喻语言，而不是使用字面替代方案？例如，是什么促使人们说“掌握含义”而不是在特定环境中“理解含义”？许多NLP的隐喻语言方法都取决于认知和（心理）语言见解，并成功定义了话语连贯性，抽象性和情感的模型。在这项工作中，我们构建了五个简单的模型，这些模型依靠已建立的认知和语言特性 - 频率，抽象，情感，话语相干性和上下文化的单词表示 - 预测在上下文中使用隐喻与同义文字表达的使用。通过将模型的输出与人类判断进行比较，我们的研究表明，我们所选的属性不足以系统地解释隐喻性和文字语言的选择。
Given a specific discourse, which discourse properties trigger the use of metaphorical language, rather than using literal alternatives? For example, what drives people to say "grasp the meaning" rather than "understand the meaning" within a specific context? Many NLP approaches to metaphorical language rely on cognitive and (psycho-)linguistic insights and have successfully defined models of discourse coherence, abstractness and affect. In this work, we build five simple models relying on established cognitive and linguistic properties -- frequency, abstractness, affect, discourse coherence and contextualized word representations -- to predict the use of a metaphorical vs. synonymous literal expression in context. By comparing the models' outputs to human judgments, our study indicates that our selected properties are not sufficient to systematically explain metaphorical vs. literal language choices.
