Abstract

Context-awareness highly depends on easy and prompt access to the right information and this needs overcoming challenges of query expression and processing of context information. One of the main considerations in querying context is selecting and applying an appropriate and expressive query language for defining user's context needs. This paper presents an overview of current languages used for querying context and investigates their strengths and limitations in expressing different aspects of context.
