Integrating massive information on the Web accurately and effectively is the important basis of developing analytic applications, such as Web information dynamic aggregation tools, market information analysis tools, public opinion analysis tools, and business intelligence tools, etc. To solve the problem that different presentations refer to the same entity during the integrating process, this paper proposes an algorithm to recognize the synonymous entities by using the snippets from the search engine and a frame of Web information integration based on synonymous entities recognition. The experimental results on hospital information integration testing data sets show that the proposed method outperforms the synonymous entities recognition based on VarientDice, VarientCosine, VarientJaccard and VarientOverlap.
