Embodiment Construction
[0047] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0048]The present invention is based on a stable marriage asymmetrical algorithm and constructs a many-to-many matching model of a large number of character strings. The optimal list of matching items of this model uses the edit distance algorithm and the longest common subsequence algorithm in the approximate matching algorithm of character strings. Combining these three algorithm technologies between the product number and product number, product name and product name, product number and product name, price and price, sales type and sales type among the product components of one's own and the other party's products, set a certain An automatic calculation of the parameter weights of , yields the best match.
