Frontiers in ICT

Towards Web 3.0

Zoran Levnajic

Life without the World Wide Web has become unthinkable, much like life without electricity or water supply. We rely on the web to check public transport schedules, buy a ticket for a concert or exchange photos with friends. However, many everyday tasks cannot be accomplished by the computer itself, since the websites are designed to be read by people, not machines. In addition, the online information is often unstructured and poorly organized, leaving the user with tedious work of searching and filtering. This book takes us to the frontiers of the emerging Web 3.0 or Semantic Web – a new generation of web aimed at bridging this gap and making the web experience accessible and easy. The Semantic Web is a vision of online information that can be readily interpreted and analyzed by machines, adapting it to user’s needs and abilities.

Contextual Navigation and Authoring in a Museum Mobile Guide37


TOGO is a tourist mobile guide dedicated TO the town of GOrizia; it proposes the study of a general model for a museum mobile guide and an application prototype related to Palazzo Coronini Crönberg, the residence of the last count of Gorizia, now museum. This paper focuses on two main open issues: the innovative contribute offered by a contextual navigation based on semantic interconnections and the importance to create personal workspaces for the users, enabling them to author new tourist paths. In order to capture semantic interconnections among data, we use advanced data structures called zz-structures, a graph-centric system of conventions for data and computing, able to offer semantic modalities of navigation.

In parallel with the wide diffusion of mobile systems and devices, as tablets and smartphones, the number of tourist mobile guides is rapidly increasing1: they provide travellers with information, services, events, and tours related to cities, museums, cultural heritage sites, etc.. In despite of the large number of them, in the major part of the cases, they share same drawbacks: do not offer personalization; do not manage dedicated user workspaces; do not provide semantic navigation; do not enable users to insert their preferred tours or to create new travel plans.

The work we present in this paper studies these limitations and proposes TOGO (TO GOrizia), a general contextual model for a tourist mobile guide, and a prototype dedicated to Palazzo Coronini Crönberg...
