Proposal for a User Modeling Markup Language

Abstract

A unified markup language for User Modeling should be a key issue in the research community. Standardization is of great importance but single applications also call for very specific solutions. With UserML, we try to contribute some aspects and try to feed into future standardization efforts. One purpose of the UserML project is to develop a platform for the communication about partial user models in an ubiquitous computing environment, where all different kinds of systems work together work together to satisfy the user's needs. Jon Orwant claims in his Doppelgänger project that we need a protocol for encoding information about users, that any given user modeling system should be able to benefit from others and that user models should follow you around.
