Natural language inference(NLI)is a challenging task to determine the relationship between a pair of sentences.Existing Neural Network-based(NN-based)models have achieved prominent success.However,rare models are interpretable.In this paper,we propose a Multi-perspective Entailment Category Labeling System(METALs).It consists of three categories,ten sub-categories.We manually annotate 3,368 entailment items.The annotated data is used to explain the recognition ability of four NN-based models at a fine-grained level.The experimental results show that all the models have poor performance in the commonsense reasoning than in other entailment categories.The highest accuracy difference is 13.22%.

语言知识驱动计算机正确地处理自然语言,介词结构知识对自然语言处理和语言教学研究有很重要的意义.本文基于大规模语料库构建了高质量的介词结构搭配库.首先在前人研究的基础上对介词进行归类并建立了介词搭配知识体系,而后设计并实现了从大数据中获取介词结构搭配知识的规则,最后对抽取结果及其数据规模进行了统计和评估.主要目的是通过形式手段获取高质量的介词结构搭配,同时也为自然语言处理和语言学基础及应用研究提供数
神经网络语言模型应用广泛但可解释性较弱,其可解释性的一个重要而直接的方面表现为词嵌入向量的维度取值和语法语义等语言特征的关联状况.先前的可解释性工作集中于对语料库训得的词向量进行知识注入,以及基于训练和任务的算法性能分析,对词嵌入向量和语言特征之间的关联缺乏直接的验证和探讨.该文应用基于语言知识库上的伪语料法,通过控制注入语义特征,并对得到的词向量进行分析后取得了一些存在性的基础性结论:语义特征可

性别偏见是社会学研究的热点.近年来,机器学习算法从数据中学到偏见使之得到更广泛的关注,但目前尚无基于语料库的方法对文本数据中职业性别偏见的研究.该文基于标记理论,利用BCC和DCC语料库,从共时和历时两个层面考察了63个职业的性别无意识偏见现象.首先,以调查问卷的形式调研了不同性别和不同年龄段的人群对63个职业的性别倾向,发现和BCC语料库中多领域的职业性别偏见度呈显著的正相关.然后从共时的角度,
