使用Python 开发一个文本聚类系统:将文本转换成向量,结合 LDA 话题模型和 VSM 模型计 算文本特征向量之间的相似度,利用谱聚类算法实现对文本的聚类分析. - nickjames21119/Text-Clustering
PyTextClassifier: Python Text Classifier. It can be applied to the fields of sentiment polarity analysis, text risk classification and so on, and it supports multiple classification algorithms and clustering algorithms.pytextclassifier is a python Open Source Toolkit for text classification. The goal ...
通常前者称为分类,后者称为聚类(clustering),后文中提到的分类都是指有指导的学习过程。 给定分类体系,将文本集中的每个文本分到某个或者某几个类别中,这个过程称为文本分类(text categorization)。将文本集合分组成多个类或簇,使得在同一个簇中的文本内容具有较高的相似度,而不同簇中的文本内容差别较大,这个过...
python 编程算法 文本聚类简单实现_文本聚类分析 聚类算法编程算法 文本聚类( text clustering ,也称文档聚类或 document clustering )指的是对文档进行的聚类分 析,被广泛用于文本挖掘和信息检索领域。 最初文本聚类仅用于文本归档,后来人 们又挖掘 出了许多新用途,比如改善搜索结果、生成同义词,等等。
