The invention discloses a demand normalization method and
system between demand documents. The method comprises the following steps of atomic demand extraction, atomic demand blood
relationship analysis and description and demand normalization. The
system comprises an atomic demand extraction module, an atomic demand blood
relationship analysis and description module, a demand normalization module and the like. According to the method, atomic demands are extracted from an original demand document, inheritance and dependency relationships among the atomic demands are constructed through Chinese semantic understanding ability of a
large model, so that a blood relationship network of all the atomic demands of the demand document is formed through convergence, and then the atomic demands are obtained according to the distance sequence of the blood relationship. The method comprises the following steps: fusing atomic demands with a blood relationship from far to near to form an atomic demand
package, integrating and unifying the atomic demand
package into a target container document to realize normalization
processing of a demand document, summarizing demand contents with an association relationship with the current demand document to a current document step by step, and storing the demand contents in the target container document. Therefore, other documents do not need to be browsed back and forth when the current document is read, the manual
workload is reduced, and the working efficiency is improved.
