摘要:

近年来,将英语作为第二语言(ESL)学习的人数已经超过了以英语为母语的人数。最近的工作已经证明了基于阅读难度提供个性化内容的成功,例如信息检索和摘要。然而,几乎所有先前的阅读困难的研究是专为母语者,而不是非母语读者。在这项研究中,我们调查了ESL读者的各种特征,通过进行线性回归来估计英语语言源的阅读水平。这种估计不仅基于词汇和句法特征的复杂性,而且还基于几个新的概念,包括从几个来源获得的单词和语法的年龄,WordNet的词义以及句子之间的隐含关系。通过使用贝叶斯信息准则(BIC)来选择最优模型,我们发现单词数量、单词获取年龄和句法分析树高度的组合比其他竞争模型产生更好的结果。因此,我们的研究结果表明,建议的第二语言阅读难度估计优于其他第一语言阅读难度估计。

英文摘要:

In recent years, the number of people studying English as a second language (ESL) has surpassed the number of native speakers. Recent work have demonstrated the success of providing personalized content based on reading difficulty, such as information retrieval and summarization. However, almost all prior studies of reading difficulty are designed for native speakers, rather than non-native readers. In this study, we investigate various features for ESL readers, by conducting a linear regression to estimate the reading level of English language sources. This estimation is based not only on the complexity of lexical and syntactic features, but also several novel concepts, including the age of word and grammar acquisition from several sources, word sense from WordNet, and the implicit relation between sentences. By employing Bayesian Information Criterion (BIC) to select the optimal model, we find that the combination of the number of words, the age of word acquisition and the height of the parsing tree generate better results than alternative competing models. Thus, our results show that proposed second language reading difficulty estimation outperforms other first language reading difficulty estimations.
