applications are intended to facilitate the adaptation of services in a
pervasive computing system. The semantic similarity between contexts
and the application of a semantic similarity measure as a mechanism for
service adaptation are topics that have yet to be thoroughly explored
in the literature. This study measured semantic similarities between
quantitative contextual and categorical variables in the field of
pervasive computing. The measure was applied to a current context and
to several reference contexts, which were predefined based on a
contextual data set. Built on the overlap measure because of its
simplicity, the proposed weighted method is easy to implement and can
be used to evaluate the actual weight of each contextual variable.
