自然语言处理(NLP)已经成为现代系统的一部分,它呗广泛的应用于搜索引擎,人机对话接口,文档处理等等。机器能够很好的处理结构化的数据。但是当它遇到无固定形式的文本时,将很难处理。NLP的目的是研究一种能够让计算机明白无结构的文本,并且帮助他们理解这种语言。 处理无结构的自然语言的最大的一个挑战是词的数量之多,...
词干提取和词形还原是英文语料预处理中的重要环节。虽然他们的目的一致,但是两者还是存在一些差异。 本文将介绍他们的概念、异同、实现算法等。 词干提取和词形还原在 NLP 中在什么位置? 词干提取是英文语料预处理的一个步骤(中文并不需要),而语料预处理是NLP的第一步,下面这张图将让大家知道词干提取在这个知识结构...
Stemming is a text preprocessing technique innatural language processing(NLP). Specifically, it is the process of reducing inflected form of a word to one so-called “stem,” or root form, also known as a “lemma” in linguistics.1It is one of two primary methods—the other beinglemmatizati...
