Using Semantic Similarities to Instrument Informal Learning Activities in Ubiquitous Environments

Our work focuses on the support of informal learning during museums visits. We consider the use of mobile devices to provide to visitors two categories of situated interactions within the museum : exploration (i.e. to suggest visitors other artworks, styles, themes or artist he may consider) and assessment (to allow visitors to assess their knowledge using micro-games). To take into account the situated nature of a museum visit, these interactions are contextualized depending on the visitor´s profile (e.g. interest) and physical situation (e.g. artworks around him, history of visit). To that end, we propose a semantic model of artworks and visitor´s context and define semantic similarities and contextual adequacy computation over this model to propose relevant interactions depending on the artwork considered by the user together with his cognitive and contextual situation.
