If the words of natural human language possess a universal positivity bias, as assumed by Boucher and Osgood's (1969) famous Pollyanna hypothesis and computationally confirmed for large text corpora in several languages (Dodds et al., 2015), then children and youth literature (CYL) should also show a Pollyanna effect. Here we tested this prediction applying an unsupervised vector space model-based sentiment analysis tool called (Jacobs, 2019) to two CYL corpora, one in English (372 books) and one in German (500 books). Pitching our analysis at the sentence level, and assessing semantic as well as lexico-grammatical information, both corpora show the Pollyanna effect and thus add further evidence to the universality hypothesis. The results of our multivariate sentiment analyses provide interesting testable predictions for future scientific studies of literature.
如果正如布彻和奥斯古德（1969）著名的“波莉安娜假说”所假设的那样，自然人类语言的词汇具有普遍的积极偏向，并且已通过计算在多种语言的大型文本语料库中得到证实（多兹等人，2015），那么儿童和青少年文学（CYL）也应该表现出“波莉安娜效应”。在此，我们通过一种名为（雅各布斯，2019）的基于无监督向量空间模型的情感分析工具，对两个儿童和青少年文学语料库进行了测试，一个是英文语料库（372本书），另一个是德语文语料库（500本书）。我们将分析定位在句子层面，并评估语义以及词汇语法信息，两个语料库均显示出“波莉安娜效应”，从而为普遍性假说增添了进一步的证据。我们的多变量情感分析结果为未来文学的科学研究提供了有趣的可测试预测。
