Abstract This paper gives a new method of information extraction based on calculation of sentence similarity. The topics of the sentences in testing words are labeled by adopting the method of calculation of sentence similarity. The veracity is increased by referencing the distributing of probability of the sentences in the documents. Using the resources of personal information on Internet, the paper achieves a statistic result.
