进化式信息过滤方法从多个角度描述用户的信息需求 ,通过类似自然选择的过程 ,达到系统整体过滤性能的优化 .同时还从面向对象程序设计语言的设计思想中获得启发 ,引入了继承、类树的概念 ,增加了过滤系统的易用性 .这种方法可以缩短训练时间 ,提高过滤质量 ,同时减小过滤结果与训练次序的相关性 Evolutionary information filtering method can describe the information needs of users from multiple perspectives and achieve the optimization of the overall filtering performance through a process similar to natural selection.At the same time, it also gets inspiration from the design idea of ​​object-oriented programming language and introduces inheritance and class The concept of tree increases the ease of use of the filtering system, which reduces training time, improves filtering quality, and reduces the correlation between filtering results and training sequence
