本项目立足于青少年成长与发展的新视角，针对过度推荐所诱发的“过滤气泡”、“信息窄化”等问题，应用情报学、心理学和信息科学等多学科理论与方法，探索面向青少年网络适应的个性化信息服务优化方法：（1）从人的发展和适应角度提出青少年“网络适应”的概念及内容指标体系，开发其量表并利用脑神经证据进行验证。（2）通过构建用户信息服务使用行为模型和量化评价个性化信息服务的“过滤气泡”效应，探索青少年网络适应与“过滤气泡”效应的互动演化机制，获取青少年网络适应增强的服务使用行为关键特征。（3）基于网络适应指标及网络行为关键特征，构建用户网络适应水平的大数据预测模型，提出面向青少年网络适应的个性化信息服务优化方法。（4）开发面向青少年网络适应的个性化信息服务原型系统，并结合青少年成长守护平台进行实证。本研究旨在引入青少年网络适应需求重构智能推荐算法，促进青少年网络适应和个性化信息服务的良性协同发展。

With a view of adolescent growth and development, this project aims at the problems like "filtering bubbles" and "narrowing information" caused by over-personalized recommendation, applies theories and methods from information science, psychology and computer science, etc., explores adolescent internet adaptation-oriented optimization for personalized information service.. Firstly, from the perspective of human development, put forward the concept and evaluation index system of adolescent internet adaptation, and its scale is developed and verified by using evidence of cranial nerves. . Secondly, by constructing user behavior model and quantitatively evaluating the "filtering bubble" effect of personalized information service, this project explores the mechanics of interaction between adolescent internet adaptation and "filtering bubble" effect, find out the key user behavior characteristics of adolescent internet adaptation, which potentially useful in personalized information service optimization.. Thirdly, based on the key user behavior characteristic and adolescent internet adaptation, building a big-data driven prediction model for adolescent internet adaptation, proposing an adolescent internet adaptation oriented personalized information service optimization method.. Finally, developing a prototype system for internet adolescent adaptation-oriented optimization of personalized information service, accessing the “Adolescent Growth Guardian Platform” to conduct empirical research. This project is of great theoretical value and practical significance for optimizing intelligent recommendation algorithm and promoting the development of adolescent internet adaptation and personalized information service.
