User Modeling

Machine learning, the study of algorithms that improve their performance with experience, offers a source of techniques that are designed to exploit multiple training instances to improve selection effectiveness [22]. Machine learning is one component of ``user modeling,'' a discipline which is concerned with both how information about users can be acquired and used by automated systems.gif The models we consider in this report are what Rich has called ``individual user, long-term user models'' [33].
