摘要:

风格转换处理的是将一段文本的风格属性转换为另一段文本的风格属性,同时确保保留核心内容的算法。由于文本风格转换在定制文本生成中的广泛应用,文本风格转换领域引起了人们的极大兴趣。现有的作品评估的风格转移模型的基础上的内容保存和转移强度。在这项工作中,我们提出了一个基于强化学习的框架,直接奖励这些目标指标的框架,从而更好地转移目标风格。我们提出的框架的基础上,自动和人工评价三个独立的任务,其中我们转移的文本风格从正式到非正式的,高兴奋低兴奋,现代英语,英语,反之亦然,在所有三种情况下,我们的性能得到了改善。与现有的最先进的框架相比,所提出的框架的性能有所改善,这表明该方法是可行的。

英文摘要:

Style transfer deals with the algorithms to transfer the stylistic properties of a piece of text into that of another while ensuring that the core content is preserved. There has been a lot of interest in the field of text style transfer due to its wide application to tailored text generation. Existing works evaluate the style transfer models based on content preservation and transfer strength. In this work, we propose a reinforcement learning based framework that directly rewards the framework on these target metrics yielding a better transfer of the target style. We show the improved performance of our proposed framework based on automatic and human evaluation on three independent tasks: wherein we transfer the style of text from formal to informal, high excitement to low excitement, modern English to Shakespearean English, and vice-versa in all the three cases. Improved performance of the proposed framework over existing state-of-the-art frameworks indicates the viability of the approach.
