Abstract

The invention discloses a text paragraph identification comparison method and a text paragraph identification comparison system based on a longest common subsequence. The text paragraph identificationcomparison method comprises the steps of acquiring a first text character string and a second text character string; performing paragraph identification on the first text character string and the second text character string; performing paragraph order adjustment on the first text character string and the second text character string; and comparing the first text character string and the second text character string which are subjected to paragraph order adjustment to obtain a difference item. The text paragraph identification comparison system comprises a front end, a conversion module, a paragraph identification module and a comparison module. With the text paragraph identification comparison method and the text paragraph identification comparison system based on the longest common subsequence, the problems that texts whose paragraph information cannot be acquired cannot be compared and the paragraph adjustment situation cannot be processed well in an existing text comparison tool are solved.

Description

technical field [0001] The present application relates to the field of text processing, in particular, to a method and system for identifying and comparing text paragraphs based on the longest common subsequence. Background technique [0002] In contemporary society, many companies have a large number of internal documents, such as contracts, instructions, tenders, etc. These documents have a high degree of similarity with only a few differences, and there is often a need to compare documents.

In the past, manual comparison was often used, which was inefficient and error-prone, and document comparison tools were created. [0003] The current document comparison tools, such as Word’s built-in comparison function, take the entire document...
