Abstract

The invention relates to a commodity property clustering method based on user comments, and belongs to the field of data mining. The method comprises the following steps: combining user comments information and commodity property information; calculating the feedback rates of the properties of commodities with similar characteristics according to the user comments; calculating the similarity of the commodities by taking the feedback rate as a weight; re-sequencing the commodities; returning needed commodities comprising real information to a user. By adopting the commodity property clustering method, commodities with most real good comments can be directly screened in concerned commodity properties of the user, so that the commodity selecting and purchasing time is saved, and the shopping experience of the user is improved.

Description

technical field [0001] The invention relates to a commodity attribute clustering method based on user comments, which belongs to the field of data mining.
