Xufa Wang · Mini-micro Systems · 2007
In this paper, the characteristics and disadvantages of several common automatic keyword extraction methods are introduced firstly. Then based on the ideas of KeyGraph algorithm, a new automatic keyword extraction method is proposed. After analysing and comparisons, the advantages of the new algorithm are revealed: the extracted words can represent more information of the document content, and the low frequent but important terms can also be extracted. Compared with the classic TF and TFIDF algorithms, a satisfying result has been gotten from the experiment and analysis.
