一种改进的TFIDF网页关键词提取方法
AN IMPROVED TFIDF-BASED APPROACH TO EXTRACT KEY WORDS FROM WEB PAGES
摘要
Abstract
Although the classical TFIDF-based keywords extraction method is easy to implement and has low time cost,its results are not good enough to acquire features which play key roles in the text content. This paper proposes such a method,it uses the improved TFIDF formula to extract keywords by means of extended synonym dictionary and based on the considerations of the structure feature of Chinese texts and the lexical category feature of Chinese words and phrases. Experimental results show that our method outperforms the classical method evidently, and is able to extract satisfied results.关键词
