Description

一种英语文本中句子语法错误自动纠正方法
技术领域
本发明涉及自然语言处理技术，是一种英语文本中句子语法错误自动纠正方法，本发明的方法只适合自动纠正英语文本中句子的语法错误，不适合自动纠正中文文本中句子的语法错误。
背景技术
传统的英语文本语法错误纠正方法主要分为两类，一类是基于规则的英语文本中句子语法错误纠正方法，一类是基于统计的英语文本中句子语法错误纠正方法。基于规则的英语文本中句子语法错误纠正方法需要人为定义语法规则，将大量的语法规则构建为语法规则库，采用构建的语法规则库对英语文本中的语法错误进行纠正，由于基于规则的英语文本中句子语法错误纠正方法难以概括所有语法错误，因此它的纠错精度低且难以提升。基于统计的英语文本中句子语法错误纠正方法通过构建语法纠错统计模型，采用构建的语法纠错统计模型对英语文本中的语法错误进行纠正，由于基于统计的英语文本中句子语法错误纠正方法无法纠正距离长的语法错误，因此它的能够纠正的语法错误类型少且难以提高。针对上述问题，本发明提出了一种英语文本中句子语法错误自动纠正方法，该方法解决了基于规则的英语文本中句子语法错误纠正方法纠错精度低的问题，以及基于统计的英语文本中句子语法错误纠正方法纠正的语法错误类型少的问题。
发明内容
本发明的一种英语文本中句子语法错误自动纠正方法包括：句子上下文词向量表示模块、句子最佳候选句子推荐模块、句子语法错误纠正生成模块，总体处理流程图如图1所示。
本发明的句子上下文词向量表示模块的处理流程是：第一，读入待处理英语文本，将其切分成句子并进行单词词性标注；第二，根据单词词性标注进行句法依存关系分析和单词依赖关系分析，得到待处理英语文本的句法关系树和单词依赖关系树；第三，根据待处理英语文本的句法关系树和单词依赖关系树，对待处理英语文本中句子进行单词的向量化处理，得到句子中单词的词向量；第四，初始化搜索权重矩阵、标记权重矩阵和结果权重矩阵，计算句子中单词的搜索向量、标记向量和结果向量；第五，计算句子中单词注意力权重、句间注意力向量和上下文词向量，最后输出待处理英语文本中句子上下文词向量表示。
本发明的句子最佳候选句子推荐模块的处理流程是：第一，读取待处理英语文本中一个句子的上下文词向量表示，采用奇异值分解对句子上下文词向量进行降维处理；第二，将降维后的句子上下文词向量与单词的词向量进行合并；第三，将合并后的词向量进行数值缩放和归一化处理；第四，计算英语单词词典中所有单词的下一个单词出现概率，并把概率最高的前5个单词作为候选单词，分别基于每一个候选单词进行推理，得到基于该单词的新候选单词；第五，把候选单词构成的句子中概率最大的句子作为候选句子，对选取的候选句子概率进行累加，并判断候选句子的累加概率是否达到设定的阈值，如果是则停止选取新的候选句子，并输出选取的所有候选句子；如果否则继续选取概率最大的句子添加到候选句子集中；第六，判断英语文本中句子是否处理完，如果是则输出英语文本中所有句子的候选句子集，否则返回第二步继续处理英语文本中剩余的句子，直至处理完待处理英语文本中的所有句子为止。
本发明的句子语法错误纠正生成模块的处理流程是：第一，读取待处理英语文本中句子的全部候选句子，并选取概率最高的候选句子作为语法纠错的结果；第二，统计待处理英语文本中出现的语法错误总数，计算待处理英语文本的语法纠错得分，并根据待处理英语文本的语法纠错得分输出相应的语法纠错建议。
本发明纠正方法的计算公式定义
(1)搜索向量、标记向量和结果向量的计算公式
搜索向量j＝搜索权重矩阵×英语文本中单词j (1)
标记向量j＝标记权重矩阵×英语文本中单词j (2)
结果向量j＝结果权重矩阵×英语文本中单词j (3)
在公式(1)、(2)、(3)中，j为英语文本中单词顺序的编号。
(2)单词注意力权重的计算公式
Figure BDA0003205949390000021
在公式(4)中，i为英语文本中第i个单词的编号，搜索向量、标记向量与结果向量由公式(1)(2)(3)计算得到。
(3)句间注意力向量的计算公式
