This study investigates Nigerian and English interjections and emojis used for expressing surprise in Nigerian online communication. Interested in the factors influencing the choice between a shocked emoji and an English or Nigerian interjection, we apply automated emotion analysis and a language detection measurement we developed for an 840-million-word web forum corpus to test the influence of these and further variables on the choice of a surprise item. Our multinomial regression model suggests that the probability of Nigerian interjections is higher in messages containing Nigerian Pidgin, informal orthographically lengthened words, and positive emotions, while the shocked emoji occurs in negative contexts, in messages by established forum members, and alongside other emojis. The sad emoji, however, favors English-language interjections, as do high arousal and emotionally laden words. Moreover, we argue that interjections are not only a spoken phenomenon but occur in any type of communication characterized by interactivity and emotional involvement.

尼日利亚在线交流中的感叹词和表情符号

本研究调查了尼日利亚和英语的感叹词和表情符号，用于在尼日利亚在线交流中表达惊讶。对影响震惊表情符号和英语或尼日利亚语感叹词之间选择的因素感兴趣，我们应用自动情绪分析和我们为 8.4 亿字的网络论坛语料库开发的语言检测测量来测试这些和更多变量对一个惊喜项目的选择。我们的多项回归模型表明，在包含尼日利亚 Pidgin、非正式正字法加长词和积极情绪的消息中，尼日利亚语感叹词的概率更高，而震惊表情符号则出现在消极语境、已建立论坛成员的消息中以及其他表情符号中。然而，悲伤的表情符号偏爱英语感叹词，高唤醒和情绪化的话语也是如此。此外，我们认为感叹词不仅是一种口语现象，而且出现在任何以交互性和情感参与为特征的交流中。
