文中提出了一种 基于 TF-IDF(TermFrequency-InverseDocumentFrequency,词频-逆文档频率)和 TextRank(文本排序)的中文文本 关键词提取方法,该方法首先采用分词,去除停用词等对文本进行预处理;其次使用 TF-IDF算法计算每个词的重要 性并进行归一化处理,同时使用 TextRank算法权衡单词之间的关系并计算每个单词的得分以进行...
TF-IDF is a method which gives us a numerical weightage of words which reflects how important the particular word is to a document in a corpus. A corpus is a collection of documents. Tf is Term frequency, and IDF is Inverse document frequency. This metho
