An Agent-Based Approach to Adapt Multimedia Web Content in Ubiquitous Environment

Nowadays, Ubiquitous Computing allows a high number of multimedia contents to be accessible anywhere and anytime by using several devices, also characterized from limited computational and storage resources. To support users in multimedia choices, different recommender systems have been proposed in the past, but any of them considers the effects of the exploited devices, even though users show different behaviours in presence of different devices. This chaptertries to give a contribution in this setting, proposing a new agent-based recommender system in which each device is provided with a client agent able to monitor the user’s behaviour performed on that device. A unique server agent associated with that user collects from his/her devices this information to build a global profile, periodically returned to the client agents. Finally, recommendations of multimedia resources are generated from the collaboration among a recommender agent, associated with a Web site, and the client agent running on the device currently exploited by the user. Some experiments confirm the high quality of the recommendations generated by the proposed approach. DOI: 10.4018/978-1-61350-107-8.ch003
