Sarcasm expression is a pervasive literary technique in which people intentionally express the opposite of what is implied. Accurate detection of sarcasm in a text can facilitate the understanding of speakers’ true intentions and promote other natural language processing tasks, especially sentiment analysis tasks. Since sarcasm is a kind of implicit sentiment expression and speakers deliberately confuse the audience, it is challenging to detect sarcasm only by text. Existing approaches based on machine learning and deep learning achieved unsatisfactory performance when handling sarcasm text with complex expression or needing specific background knowledge to understand. Especially, due to the characteristics of the Chinese language itself, sarcasm detection in Chinese is more difficult. To alleviate this dilemma on Chinese sarcasm detection, we propose a sememe and auxiliary enhanced attention neural model, SAAG. At the word level, we introduce sememe knowledge to enhance the representation learning of Chinese words. Sememe is the minimum unit of meaning, which is a fine-grained portrayal of a word. At the sentence level, we leverage some auxiliary information, such as the news title, to learning the representation of the context and background of sarcasm expression. Then, we construct the representation of text expression progressively and dynamically. The evaluation on a sarcasm dateset, consisting of comments on news text, reveals that our proposed approach is effective and outperforms the state-of-the-art models. 相似文献

在汉英翻译中,有大量义位不对称的现象。造成翻译中汉英义位不对称的表层动因包括汉英义场的切分差异、汉英词项的标记性差异及韵律因素等,其深层动因则涉及语际转喻。 相似文献

谈汉语的义素和义位的研究 总被引：1，自引：0，他引：1
林新年 《福建师大福清分校学报》2003,(3):59-64
义素和义位是语义学理论的两个最基本的概念，也是在具体研究中十分重要的基本单位。而在对它们性质的认识和界定、在将西方语义学的理论应用于汉语研究中，出现了诸多的问题和争论，本重点讨论了义素的性质和义素的研究方法，认为从语素义入手研究义素在理论和实际操作中都存在诸多的问题，而以“元语言”来确定意义的最小单位和构成方式是较为可行的方式：在义位研究上。本分析了以义项方式进行义位研究的利弊，批评了扩大附属义的研究倾向。 相似文献
