We propose a new area to focus upon as a research challenge: How to use personalized technology to connect our cultural heritage experiences to our "daily" lives. In particular we want to connect the visitor's museum experiences with outside relevant mobile cultural heritage experiences. We begin to examine what processes and technologies will be necessary to accomplish the when, what and how of this challenge.

ContextOver the years, several modeling languages for requirements have been proposed. These languages employ different conceptual approaches, including scenario-based and goal-oriented ones. Empirical studies providing evidence about requirements model comprehensibility are rare, especially when addressing languages that belong to different modeling approaches.Objective This work aims to compare the comprehensibility of requirements models expressed in different but comparable modeling approaches from a requirement analysts’ perspective. In particular, in this paper we compare the comprehensibility of requirements models expressed in two visual modeling languages: Use Case, which is scenario-based, and Tropos, which exploits goal-oriented modeling. We further compare the effort required for comprehending the different models, and the derived productivity in each case.Method Requirements model comprehensibility is measured here in the context of three types of tasks that analysts us...

The present study compares an adaptive simulated cellular-phonebased recommender system to a non-adaptive one, in order toevaluate user preferences with respect to system adaptivity. Theresults show that users prefer the adaptive system over the nonadaptive one even after minimal interaction with the system.

This book constitutes the refereed post-conference proceedings of the 7th International Conference on Next Generation Information Technologies and Systems, NGITS 2009, held in Haifa, Israel, in June 2009. The 14 revised full papers presented together with two keynote lectures and one invited paper were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on middleware and integration, modeling, healthcare/biomedical, service and information management, and ...

Abstract Cultural heritage (such as museums, archeological sites etc) is both an appealing and challenging research area for applying novel information technologies. It is appealing because it provides a wide range of research possibilities and involves users that are generally willing to experience novel technologies. It is challenging because it requires the research prototype to be a complete, robust and high quality system usable by regular visitors. However, once such a system is in place then a wide range of research directions ...

Abstract. User modeling data in dynamic, personal and adaptable systems is usually collected immediately before system interaction with a questionnaire, or during application execution when users' choices are recorded and analyzed. This data is then typically used to intelligently adapt the system's output, hopefully improving the user's interaction in some measurable way. When coupled with knowledge-based applications such as intelligent information presentations or tutoring systems, this user model may be mapped onto the ...

Abstract Globalization is influencing several agriculture aspects: market globalization has increased export from producing to consuming countries where different food safety or pesticide residue regulations apply, and has raised awareness of global problems linked to agriculture production (ie, chemical pesticide pollution). Pests, diseases and weeds may cause significant damages to growers and the cost of pesticide increases. Environmental pollution and risk of unwanted residues on food forced researchers to find ways to ...

Accurate initialization of a User Model (UM) is im portant for every system that provides personalized services. Howeve r, there are systems where this initialization is critical yet no user data is available from prior interactions. For example, one in which both the repeat usage by a user is rare, and the total interaction on a single use is relatively

Abstract A general paradigm for solving resource allocation, time-tabling and scheduling problems is presented. The paradigm is based on an expert system approach which looks for a feasible solution that satisfies the problem's real-life constraints, rather than on an analytic approach which looks for an optimal solution by using simplified constraints. The main feature of the new paradigm is a general control strategy which includes three parts that deal with allocation, with constraints checking and with changes to allocations, termed ...
