Problems solved by technology
First of all, due to the influence of various subjective factors such as experience and personal standpoint, the evaluation of the importance of attributes is not objective enough, and misjudgment will occur when selecting important attributes
Secondly, it will be affected by the slow response of personnel to market perception, resulting in the evaluation or selection of the importance of attributes not being able to keep pace with the market in real time

The invention provides a method and a device for selecting object attributes. The important degree of the object attributes can be objectively and immediately measured and the object attributes can be selected. The method comprises the steps: establishing a combined equation set of an object attribute value combination and aggregate utility and solving utilization coefficients of different attribute values by virtue of the combined equation set; calculating the in-attribute differential degrees in the attributes by comparing the utilization coefficients of the different attribute values in the same attribute; calculating first weights of the attributes according to the in-attribute differential degrees of the attributes; carrying out semantic analysis on the object related pre-stored data to obtain second weights of the attributes; calculating comprehensive weights of the attributes according to the first and second weights of the attributes; and selecting the attributes and outputting the selection results according to the comprehensive weights of the attributes.
Description
technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for selecting object attributes. Background technique [0002] In general, an object can have multiple attributes. For example, clothes can have attributes such as color, size, and production material, and books can have attributes such as author, publisher, and format. For the same object, some attributes are more important and some attributes are less important. In order to achieve better object selection, sales promotion, design development, etc., it is necessary to select attributes that are important to users, merchants, and manufacturers from many object attributes. [0003] In the prior art, the importance of each attribute of an object is usually measured manually and empirically. There are certain deficiencies in this way. First of all, due to the influence of various subjective factors such as experience and personal standpoint, the evaluati...
