PoKi：一个大型的儿童诗歌数据集
PoKi: A Large Dataset of Poems by Children
摘要：
儿童语言研究对于提高我们对儿童福祉的理解至关重要;特别是在确定影响幸福的因素，焦虑的来源，情绪调节的技巧以及应对压力的机制方面。然而，这项研究的大部分是由于缺乏大型儿童书面文本的可用性而受阻。我们提出了一个新的语料库的儿童写的文本，PoKi，其中包括约62000首诗写的儿童从1至12年级。PoKi在研究儿童语言方面特别有用，因为它附带了有关儿童作者年龄（他们的年级）的信息。我们沿着几个情感维度（效价，唤醒，支配）和离散的情感（愤怒，恐惧，悲伤，喜悦）分析PoKi中的单词。我们使用非参数回归模型的发展差异，从幼儿到青春期后期。结果显示，在青春期中期，效价下降尤其明显，而唤醒和支配在青春期达到顶峰。此外，还观察到情绪发展轨迹的性别差异。我们的研究结果支持并扩展了情绪发展研究的现状。
英文摘要：
Child language studies are crucial in improving our understanding of child well-being; especially in determining the factors that impact happiness, the sources of anxiety, techniques of emotion regulation, and the mechanisms to cope with stress. However, much of this research is stymied by the lack of availability of large child-written texts. We present a new corpus of child-written text, PoKi, which includes about 62 thousand poems written by children from grades 1 to 12. PoKi is especially useful in studying child language because it comes with information about the age of the child authors (their grade). We analyze the words in PoKi along several emotion dimensions (valence, arousal, dominance) and discrete emotions (anger, fear, sadness, joy). We use non-parametric regressions to model developmental differences from early childhood to late-adolescence. Results show decreases in valence that are especially pronounced during mid-adolescence, while arousal and dominance peaked during adolescence. Gender differences in the developmental trajectory of emotions are also observed. Our results support and extend the current state of emotion development research.
