Abstract: With the development of society，more and more“Sensational Headline”which does not match the text for the purpose of attracting the audiences attention phenomena has appeared． In order to identify the “Sensational Headline”news，methods of text similarity calculation based on an Improved VSM Combined with Cosine Similarity Method，the HowNet Method and an Improved VSM-HowNet Fusion Similarity Algorithm are introduced． These methods have higher total accuracy，total recall rate and total F1 value for the“Sensational Headline”news recognition than other text similarity calculation methods． For identifying an unknown type of news，the improved VSM-HowNet fusion similarity algorithm is more advantageous than other text similarity calculation methods．

Key words: “Sensational Headline”news, improved VSM combined cosine similarity method, HowNet method, improved VSM-HowNet fusion similarity algorithm
