When building adaptive systems, close attention must be paid to management of the user model, to ensure its ability to conform its behavior to the needs of different users. In recent years it has become possible to develop so-called cooperative, or open models. During modeling by interaction the system obtains the necessary information directly from the user by means of a dialog in which the student and tutor (system) build the student model according to a collaborative process. In the present work we describe the overall architecture required for a system to be able to use our cooperative model COSMO, proposed in previous work. The COSMO model has been implemented in a prototype system and experimented at primary school level in the math domain, addressing the learning of fractions.

Abstract
When building adaptive systems, close attention must be paid to management of the user model, to ensure its ability to conform its behavior to the needs of different users. In recent years it has become possible to develop so-called cooperative, or open models. During modeling by interaction the system obtains the necessary information directly from the user by means of a dialog in which the student and tutor (system) build the student model according to a collaborative process. In the present work we describe the overall architecture required for a system to be able to use our cooperative model COSMO, proposed in previous work. The COSMO model has been implemented in a prototype system and experimented at primary school level in the math domain, addressing the learning of fractions. This study describes a first attempt to generalize the architecture of the prototype system developed to test the COSMO model.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
