A current trend in modern HCI is represented by Embodied Conversational Agents (ECAs), even designed to run on the Web. They are virtual 3D human-like front ends coupled with software agents that are able to engage in a conversation with a user and execute complex tasks, such as, for example, searching for some specific information or ordering some items from the catalogue of an online shop. This paper presents SAMIR system, a framework to build intelligent agents for the Web. SAMIR consists of a 3D face which is animated to exploit expressions which are perceived by the user; a custom version of the ALICE chatterbot to chat with the user; and finally an XCS classifier system to deal with the problem of keeping conversation and face expressions coherent with each other. Experimental results, taken from an online bookstore-based scenario, are presented at the end.

Abstract
A current trend in modern HCI is represented by Embodied Conversational Agents (ECAs), even designed to run on the Web. They are virtual 3D human-like front ends coupled with software agents that are able to engage in a conversation with a user and execute complex tasks, such as, for example, searching for some specific information or ordering some items from the catalogue of an online shop. This paper presents SAMIR system, a framework to build intelligent agents for the Web. SAMIR consists of a 3D face which is animated to exploit expressions which are perceived by the user; a custom version of the ALICE chatterbot to chat with the user; and finally an XCS classifier system to deal with the problem of keeping conversation and face expressions coherent with each other. Experimental results, taken from an online bookstore-based scenario, are presented at the end.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
