Abstract: 【Purpose/significance】Exploring parent-child reading preferences has important reference value in guiding the purchase of parent-child reading materials. By analyzing the online consumption evaluation of parent-child reading materials, we can deeply ex⁃ plore the dimensional elements that affect parent-child reading preferences, which has theoretical significance and practical value in improving the quality and interest of parent-child reading【. Method/process】Evaluate parent-child reading preferences from four di⁃ mensions: material, form, theme content, and social perceived value. Establish an online consumption evaluation preference model based on an emotional dictionary, extract emotional words and calculate emotional values from comment texts, obtain emotional data in online consumption evaluation, and draw a preference word label cloud and dynamic preference trend curve for online consumption evaluation【. Result/conclusion】The results of online consumption evaluation analysis indicate that young children are more likely to be attracted to environmentally friendly materials and unique forms of reading materials; With the development of cognitive stage, parentchild reading preferences gradually shift towards focusing on the theme content; Pay attention to enhancing social perceived value【. In⁃ novation/limitation】This article constructs an evaluation model for parent-child reading preferences, and visualizes the emotional evaluation of online consumption around the dimension of parent-child reading preferences. This article only extracts emotional data from online consumption evaluation through sentiment analysis technology, without conducting in-depth interviews with specific con⁃ sumers, and fails to provide a comprehensive overview of parent-child reading preferences based on online consumption evaluation.
