Service architecture, prototype description, and network implications of a personalized information grazing service

A passive information grazing system (PIGS) is presented which is a prototype information delivery and filtering system for casual users. In PIGS, information articles in multimedia form are electronically transmitted to users over a prototype broadband network. To assist users in managing the potential flood of articles, PIGS selects information for individual users based on their personalized interest profiles. As users' interests change over time, their profiles could be automatically adapted using implicit and explicit feedback about each article. An examination is made of PIGS, with particular emphasis on transmission and call processing capacity requirements.<
