论文摘要
关于隐喻语言的研究表明，抽象性与情感性与隐喻性有关。但是，先前的工作仅限于单词和句子级别，最新的尚无实证研究确定在话语层面上也是如此的程度。本文探讨了哪些文本和感知性的特征是人类注释者认为对话语和表达的隐喻性很重要，并更具体地解决了两个研究问题。首先，与字面意义上的话语相比，一种隐喻感知的话语是否更加抽象和情感？其次，是否比同义文字替代方案之前的隐喻表达更为隐喻/抽象/情感上下文？我们使用了1,000份语料库提取的话语的数据集，众包注释者（1）对他们认为论述是更隐喻还是更字面的判断，并且（2）系统地列出了词汇术语，从而在（1）中触发了他们的决定。我们的结果表明，隐喻性话语比字面的话语更具情感性，并且在某种程度上更抽象。但是，上一句话语的隐喻性和抽象性和情感性似乎都在触发同义隐喻与文字表达之间的选择中起作用。我们的数据集可在https://www.ims.uni-stuttgart.de/data/discourse-met-lit上找到。
Research on metaphorical language has shown ties between abstractness and emotionality with regard to metaphoricity; prior work is however limited to the word and sentence levels, and up to date there is no empirical study establishing the extent to which this is also true on the discourse level. This paper explores which textual and perceptual features human annotators perceive as important for the metaphoricity of discourses and expressions, and addresses two research questions more specifically. First, is a metaphorically-perceived discourse more abstract and more emotional in comparison to a literally-perceived discourse? Second, is a metaphorical expression preceded by a more metaphorical/abstract/emotional context than a synonymous literal alternative? We used a dataset of 1,000 corpus-extracted discourses for which crowdsourced annotators (1) provided judgements on whether they perceived the discourses as more metaphorical or more literal, and (2) systematically listed lexical terms which triggered their decisions in (1). Our results indicate that metaphorical discourses are more emotional and to a certain extent more abstract than literal discourses. However, neither the metaphoricity nor the abstractness and emotionality of the preceding discourse seem to play a role in triggering the choice between synonymous metaphorical vs. literal expressions.
