Electronic Commerce involves more than simple online transactions, it also deals with several other fields such as market
research, customers care, document exchange and customer modeling.
Our paper deals with the customer modeling issue, first introduced in the companion paper [4], where a model is presented
of a system that can adapt its response to customers.
We present here the necessary extension to the model so that it can be used on a distributed system for EC on the World Wide
Web.
The extensions presented axe simple, easy to implement, not computationally expensive, and preserve the privacy of all the
actors in an EC distributed system, while ensuring the adaptive behaviour.
