—Social networks represent a sophisticated tool for accessing the preferences and properties of individuals and groups. Thus, they potentially allow up-to-date, richly annotated contextual data to be acquired as a side effect of users' everyday use of services. In this paper, we explore how such " social sensing " could be integrated into pervasive systems.(More)
Social networks attract lots of new users every day and absorb from them information about events and facts happening in the real world. The exploitation of this information can help identifying mobility patterns that occur in an urban environment as well as produce services to take advantage of social commonalities between people. In this paper we set out(More)
Here we present the overall objectives and approach of the SAPERE (" Self-aware Pervasive Service Ecosystems ") project, focussed on the development of a highly-innovative nature-inspired framework, suited for the decentralized deployment, execution, and management, of self-aware and adaptive pervasive services in future network scenarios. © Selection and(More)
The imminent mass deployment of pervasive computing technologies such as sensor networks and RFID tags, together with the increasing participation of the Web community in feeding geo-located information within tools such as Google Earth, will soon make available an incredible amount of information about the physical and social worlds and their processes.(More)
As pervasive computing meets social networks, there is a fast growing research field called pervasive social computing. Applications in this area exploit the richness of information arising out of people using sensor-equipped pervasive devices in their everyday life combined with intense use of different social networking services. We call this set of(More)
Modern handheld devices provided with localization capabilities could be used to automatically create a diary of user's whereabouts, and use it as a complement of the user profile in many applications. In this paper we present the Whereabouts diary, an application/service to log the places visited by the user and to automatically label them with descriptive(More)
In this paper we show how pervasive technologies can be employed on a public-display advertisement scenario to enable behavioral self-adaptation of content. We show this through MyAds, a system capable of exploiting pervasive technologies to autonomously adapt the advertisement process to the trends of interests detected among the audience in a venue. After(More)
— Web communities are making available an increasing volume of free, fresh, detailed and powerful information about living people. Among them, the Flickr photo-sharing service offers to researchers a database of several millions of geotagged pictures from users all around the world. Working on that opens the door to the study of meaningful mobility data,(More)
Pervasive computing systems can be modelled effectively as populations of interacting autonomous components. The key challenge to realizing such models is in getting separately-specified and-developed subsystems to discover and interoperate with each other in an open and extensible way, supported by appropriate middleware services. In this paper, we argue(More)
—Middleware infrastructures for pervasive computing , in order to be able to support services and users activities, have to deal with both spatially-situated and socially-situated interactions. In this paper we present the solution adopted in the SAPERE middleware that exploits the graph of a social networks, and combines it with relations deriving from(More)
