Advanced fault analysis in web service composition

Currently, fault management in Web Services orchestrating multiple suppliers relies on a local analysis, that does not span across individual services, thus limiting the effectiveness of recovery strategies. We propose to address this limitation by employing Model-Based Diagnosis to enhance fault analysis. In our approach, a Diagnostic Web Service is added to the set of Web Services providing the overall service, and acts as a supervisor of their execution, by identifying anomalies and explaining them in terms of faults to be repaired.

Interacting with a Social Web of Smart Objects for Enhancing Tourist Experiences

In this paper we introduce the idea of interaction with networks of socially intelligent objects as a way of supporting tourists and introducing them to the culture of a territory and as a way of maintaing the cultural heritage of a territory alive. We illustrate this idea with an application we designed in the field of gastronomy. Socially intelligent objects are able to maintain and aggregate knowledge about themselves and their world and are able to establish social relations with other objects and people. In this way they become hubs which allow tourists to get in touch with the world of the objects which is made of a territory, its culture and traditions, people and other objects. We support natural forms of interaction without requiring any electronic infrastructring of the objects. In particular, we designed an interaction paradigm supporting a playful enhancing experience when interacting with objects. We also support a continuum of experience in the real and virtual world.

WantEat: interacting with social networks of smart objects for sharing cultural heritage and supporting sustainability

WantEat is about interacting with everyday objects that become intelligent hubs for accessing and sharing the cultural heritage of a territory. Objects are smart in the sense that they share knowledge with users, interact with them in a personalized way and maintain social relationships with users and other objects. When interacting with an object, a user is also introduced to the social network of its friends; the user can explore this network to discover new interesting information, services, objects, people. The objects we consider belong to the realm of gastronomy, including food items, shops, restaurants, cooks, recipes, etc. On the one hand, this allows people to get deeply in touch with the culture of a territory, making people aware of its traditions and supporting a sustainable gastronomy; on the other hand, the approach supports networking and the promotion of local quality productions and economy.
