Abstract

Over the last few years, user modeling scenery is changing. With the recent advancements in ubiquitous and wearables technologies, the amount and type of data that can be gathered about users and used to build user models is expanding. User Model can now be enriched with data regarding different aspects of people’s everyday lives. All these changes bring forth new research questions about the kinds of services which could be provided, the ways for effectively conveying new forms of personalisation and recommendation, and how traditional user modeling should change to exploit ubiquitous and wearable technology to provide these services. In this paper we follow the evolution of user modeling process, starting from the traditional User Model and progressing to RWUM - Real World User Model, which contains data from a person’s everyday life. We tried to answer the above questions and to present a conceptual framework that represents the RWUM process, which might be used as a reference model for designing RWUM-based systems. Finally, we propose some inspiring usage scenarios and design directions that can guide researchers in designing novel, robust and versatile services based on RWUM.

Notes

  1. Their reliability can be increased by introducing mirrors or distributing the information across several servers (virtual centralisation of distributed User Models), where there is a unique User Model but different parts of it are separately stored on different servers (Kobsa and Fink 2006).

  2. Systems can also be implemented as mixed solutions, where the User Models are physically decentralised, while each system stores its User Models locally, referring to centralised model which includes the most used concepts in the domain, as in Berkovsky (2006), GUC (van der Sluijs and Houben 2006) and MEDEA (Musa and de Oliveira 2005).
