  • Publication number: 20040263530
    Abstract: The invention concerns a device receiving data associated with a first profile and generating data associated with a second profile, comprising means to extract facts associated with the first profile, means to extract facts associated with the second profile, a set of rules describing a way to modify facts associated with said first profile into facts associated with said second profile, means to analyze said facts associated with the first profile and said facts associated with the second profile, means to modify facts associated with said first profile into facts associated with said second profile according to said set of rules. The device is characterized in that it comprises, means to request additional rules when said set of rules does not allow to modify facts associated with said first profile into facts associated with said second profile.
