摘要:

母语使用者可以判断一个句子是否是他们语言的可接受实例。可接受性提供了一种评估计算语言模型是否以类似人类的方式处理语言的方法。我们测试的能力计算语言模型,简单的语言功能,和词嵌入,以预测母语为英语的人的判断的可接受性的非母语人士写的英语文章。我们发现,句子的可接受性方差可以捕获的组合功能,包括拼写错误,词序,单词相似性(皮尔逊的r = 0.494)。虽然预测神经模型很好地拟合了可接受性判断(r = 0.527),但我们发现具有统计平滑的4-gram模型同样好(r = 0.528)。由于纳入了拼写错误的计数,我们的4克模型超越了之前的无监督最先进的模型(Lau等人,2015年; r = 0.472)和平均非专家母语者(r = 0.46)。我们的研究结果表明,可接受性是很好地捕捉的n元统计和简单的语言功能。

英文摘要:

Native speakers can judge whether a sentence is an acceptable instance of their language. Acceptability provides a means of evaluating whether computational language models are processing language in a human-like manner. We test the ability of computational language models, simple language features, and word embeddings to predict native English speakers judgments of acceptability on English-language essays written by non-native speakers. We find that much of the sentence acceptability variance can be captured by a combination of features including misspellings, word order, and word similarity (Pearson's r = 0.494). While predictive neural models fit acceptability judgments well (r = 0.527), we find that a 4-gram model with statistical smoothing is just as good (r = 0.528). Thanks to incorporating a count of misspellings, our 4-gram model surpasses both the previous unsupervised state-of-the art (Lau et al., 2015; r = 0.472), and the average non-expert native speaker (r = 0.46). Our results demonstrate that acceptability is well captured by n-gram statistics and simple language features.
