User interesting degree model （UIDM） is constructed to justify the value of user interesting degree; the personalization approach is presented; operations of add and delete nodes （branches） are covered in this paper. The improved e-catalog is more satisfied to users＇ needs and wants than the former e-catalog which stands for enterprises, and the improved one can complete the recommendation of related products of enterDriscs.展开更多
