Modelling the context evolution in Cultural Heritage domain: A graph approach

Nowadays, smart and pervasive environments are characterized by a large number of devices and related services offered to users. Providing the most appropriate services according to users behaviour and preferences is still a challenge and strongly depends on the user's current context. How it is well known, the context is often rich of data and very dynamic, and the users aim to continuously receive information about contextualised services. In this scenario, Cultural Heritage represents a domain where exchanged and produced data can be opportunely exploited by a set of applications and services in order to make the environment smart. This paper proposes a novel approach to represent and manage the evolution of context instances driven by events adopting a graph structure. As a case study, we propose an example of context evolution in an art exhibition within the Maschio Angioino castle, in Naples (Italy).
