论文摘要
这项工作描述了隐喻释义产生的任务，在该任务中，我们被赋予了字面句子，并负责产生隐喻的释义。我们为此任务提出了两个不同的模型：词汇替代基线和序列模型“隐喻掩盖”的新序列，该模型会产生自由的隐喻释义。我们使用众包来评估我们的结果，并开发自动指标来评估隐喻释义。我们表明，虽然词汇替代基线能够产生准确的释义，但它们通常缺乏隐喻性，而我们的隐喻掩盖模型在产生隐喻句子时表现出色，而在流利度和释义质量方面几乎表现出色。
This work describes the task of metaphoric paraphrase generation, in which we are given a literal sentence and are charged with generating a metaphoric paraphrase. We propose two different models for this task: a lexical replacement baseline and a novel sequence to sequence model, 'metaphor masking', that generates free metaphoric paraphrases. We use crowdsourcing to evaluate our results, as well as developing an automatic metric for evaluating metaphoric paraphrases. We show that while the lexical replacement baseline is capable of producing accurate paraphrases, they often lack metaphoricity, while our metaphor masking model excels in generating metaphoric sentences while performing nearly as well with regard to fluency and paraphrase quality.
