已迁移到我新博客,阅读体验更佳parsing:NLP之chart parser句法分析器 完整代码实现放在我的github上:click me 一.任务要求 实现一个基于简单英语语法的chart句法分析器. 二.技术路线 采用自底向上的句法分析方法,简单的自底向上句法分析效率不高,常常会重复尝试相同的匹配操作(回溯之前已匹配过).一种基于图的句法分析技术(Chart Parsing)被提出,它把已经匹配过的结果保存起来,今后需要时可直接使用它们,不必重新匹配.(动态规划) cha

简单说一下所谓Knowledge base(知识图谱)有两条路走,一条是对用户的问题进行语义理解,一般用Semantic Parsing(语义分析),语义分析有很多种,比如有用CCG.DCS,也有用机器翻译来做的.它得到了一个句子的逻辑表示,根据逻辑表示再到知识库里去查,查到这个结点是什么,关系是什么等,通过这种方式,自然而然就查到了. 还有一种办法就是最近几年流行的信息检索方法.比如,一个问题“where was Barack Obama born ?”这句话里出现的了一个实体——Obama,
