Not surprisingly, many web sites have adopted different ways to construct user models so that they can recommend goods or services to individuals according to user's preference. Obviously, to integrate separate user models coming from different sources for one user can provide more comprehensive and accurate user information. Thus there exist the requirements to obtain integrated user models by sharing their user models. After discussing the requirements of sharing user models, an open user model service platform is presented. It's architecture, key technologies and an implemented prototype are introduced.
