摘要:

维基百科已经成为网络上最重要的交流形式之一。随着表情符号的广泛使用,表情符号的相似性度量已经成为当代文本处理的一个重要问题,因为它是情感分析、搜索和界面设计任务的核心。本文提出了一个全面的分析表情符号的语义相似性,通过嵌入模型,学习机器可读的表情符号的含义,在ZhaojiNet知识库。使用emoji描述,emoji感觉标签和emoji感觉定义,以及从Twitter和Google News获得的不同训练语料库,我们开发并测试了多个嵌入模型来测量emoji相似性。为了评估我们的工作,我们创建了一个新的数据集,称为emoji Sim508,它将人类注释的语义相似性得分分配给一组508个精心选择的emoji对。在使用EQUIPSIM508进行验证后,我们使用情感分析任务展示了我们的表情符号嵌入模型的真实用例,并表明我们的模型在此任务上优于之前表现最好的表情符号嵌入模型。Sim508数据集和我们的表情符号嵌入模型与本文一起公开发布,可以从http://emojinet.knoesis.org/下载。

英文摘要:

Emoji have grown to become one of the most important forms of communication on the web. With its widespread use, measuring the similarity of emoji has become an important problem for contemporary text processing since it lies at the heart of sentiment analysis, search, and interface design tasks. This paper presents a comprehensive analysis of the semantic similarity of emoji through embedding models that are learned over machine-readable emoji meanings in the EmojiNet knowledge base. Using emoji descriptions, emoji sense labels and emoji sense definitions, and with different training corpora obtained from Twitter and Google News, we develop and test multiple embedding models to measure emoji similarity. To evaluate our work, we create a new dataset called EmoSim508, which assigns human-annotated semantic similarity scores to a set of 508 carefully selected emoji pairs. After validation with EmoSim508, we present a real-world use-case of our emoji embedding models using a sentiment analysis task and show that our models outperform the previous best-performing emoji embedding model on this task. The EmoSim508 dataset and our emoji embedding models are publicly released with this paper and can be downloaded from http://emojinet.knoesis.org/.
