Method and device for searching contract modification part, computer equipment and storage medium

The invention discloses a method and a device for searching a contract modification part, computer equipment and a storage medium. The method comprises the following steps: establishing an editing distance matrix; Calculating the value of each element in the editing distance matrix according to the contract text and the contract template text; Obtaining a calculation track of the value of each element in the editing distance matrix, and generating a track matrix corresponding to the editing distance matrix; Screening the track with the highest similarity to obtain a target track; Determining aone-to-one correspondence relationship between the contract template text and the contract text according to the target track; And analyzing newly-added and modified text fragments in the contract text and deleted text fragments in the contract template text according to a one-to-one correspondence relationship between the contract template text and the contract text. According to the method, theone-to-one corresponding
