The English similar sentences retrieval plays an important role in the text classification, text replication detection, text clustering, and the information retrieval. It deserves our in-depth research and exploration.Traditionally similar sentences retrieval is basically based on a single node, but the single node similar sentences retrieval is less efficiency when the sample space is large. Therefore, this paper proposes a distributed retrieval method of the English similar sentences based on the edit distance. The optimization of the edit distance algorithm makes the search efficiency greatly improved.
