该文提出了古籍版本异文自动发现方法 首先由bigram计算得到句珠相似度,根据相似度发现最有可能的句珠配对,然后在异文句珠中不断地去掉最长“同文”并输出异文。研究个案是三传春秋经,结果表明,句珠配对全部正确,异文配对算法也能够正确发现全部符合定义的异文。

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.
