This paper present the Symbol Clustering Map methods that is used to recognizing the context of use of a mobile phone. The authors present an approach for context recognition that is based in a vectorial fusion of sensory information. Two sorts of fusions are presented: a multi-source fusion and a temporal fusion of events. The Symbol Clustering Map (SCM) is based on a lattice structure, generally two-dimensional, with a total of M x M lattice points. For each node k of the lattice, a symbol set is associated, combined with a weight vector.
