Abstract

The invention discloses a method for judging repetition of enterprise Chinese names on the basis of core word similarity. The method comprises the steps that the enterprises Chinese names in a B2B e-business platform database are loaded to an enterprise name data market through ETL; the enterprise Chinese names stored in the data market are processed in advance; core words of the newly-increased enterprise Chinese names are extracted according to an enterprise Chinese name core word extraction method; corresponding enterprise Chinese names with name region keywords are searched for according to enterprise Chinese name sets corresponding to the core words, and similarity between the newly-increased enterprise Chinese names and corresponding enterprise Chinese names without name region keywords is calculated through a text similarity calculation processing method taking the weight into consideration. According to the method for judging repetition of the enterprise Chinese names on the basis of core word similarity, the processing workload of matching work is reduced, and processing efficiency of the whole method is improved.

Description

technical field [0001] The invention belongs to the field of B2B e-commerce information review, in particular to a method for judging duplicate Chinese names of enterprises based on the similarity of core words.
