Abstract: To solve the problem of information redundancy in automatic abstraction, this paper proposed a method for eliminating redundant sentences in automatic abstraction. Firstly, similarity of words was defined based on TongYiCi CiLin. And then, correspondence between topic words and subject sentence was established based on the similarity of words, the similarity of subject sentence was got based on the theory of Hamming distance in encoding theory, and high similarity sentences were reduced by threshold. The experimental results show that the method greatly improves the accuracy of abstraction.
