Definition
User modeling refers to building a profile of the user’s preferences for consumption and usage. In MPEG-7, two tools are specifically implemented for user interaction, which are the User Preferences DS and the User History DS.
Just as we have to model the content to describe the rich multi faceted detail stored both semantically and structurally [1], we must also model the user in a similar fashion, building a profile of the user’s preferences for consumption and usage. The requirements are different but the concept remains similar, model the user by capturing the many multi faceted perspectives of the user that combine to describe the mental and corporeal needs of the user. The mental needs are the user’s interests and needs for specific information; the corporeal is how, when and where they would like to view that information. The main difference between content modeling and user modeling is that the former is temporally static after creation and the latter evolves...
