Automatic Detection of Version Differences Among Ancient Chinese Texts

An automatic approach to find the version differences among ancient Chinese text is proposed.First,we try to find sentence beads with the highest similarity by comparing the bigrams in the pair of sentences.Second,we iteratively remove the longest common substrings in the pair of different sentences and output differences remained.We take three versions of CHUNQIU as a running case.The results of the experiment indicate that our approach succeeds in finding all sentence beads and identifying all text differences definedas the version differences in this paper.
