    This contribution wishes to propose an addition to the existing toolbox of techniques employed to approach and render explicit the place semantics embedded in geosocial data. Inspired by the notion of relational place introduced by human geographers, we focused on people's experience of the city derived from the aggregation of the points of view of different social groups. We analysed socio-spatial behaviour under the frame of social practice theories, defining social practices as collective social actions performed by groups of people that display a similar behaviour. Applying spatial pattern analysis and clustering on data extracted from TripAdvisor platform, we classified social groups of users depending on our prior knowledge and their spatial behaviours

    Abstract—The greater and greater quantity of services that are available over the web causes a growing attention to techniques that facilitate their reuse. A web service specification can be quite complex, including various operations and message exchange patterns. In this work, we give a declarative representation of services, and in particular of WSDL operations, that enables the application of techniques for reasoning about actions and change. By means of these techniques it becomes possible to reason on the specification of choreography roles and on possible role players, as a basis for selecting services which match in a flexible way with the specifications. Flexible match is, indeed, fundamental in order to enable web service reuse but it does not guarantee the preservation of the goals, that can be proved over the role specification itself. We show how to enrich various kinds of match proposed in the literature so to produce substitutions that preserve goals. I
