The effective delivery and presentation of information is critically dependent on understanding the context in which that information is to be used. However, a keyword based approach to defining and managing context has limited effectiveness, e.g. through the prevalence of homonymy and synonymy. Context needs to be defined semantically, specifically in terms of an ontology. Moreover, the interpretation of ontologies themselves may be interpreted in the light of particular contexts.

This workshop will consider all the research challenges related to representing, managing, using and learning contextual information, bringing together researchers interested in the use of context for information delivery, the use of ontologies to define context, and the use of context to interpret ontologies.


We invite technical contributions and short statements of interest relating to the themes described above.

These include:

  • Ontologies describing user context
  • frameworks for managing user context
  • techniques for learning context through an analysis of user interaction, and through machine intelligence and linguistic techniques.
  • context-based information retrieval and information delivery
  • context-based information search
  • the application of context to the identification of tacit knowledge
  • application of context-based information management
  • context representation, e.g. context representation languages and the use of ontologies for representing context
  • user interface research – to enable users to create, use and visualise their context
  • techniques for measuring the value and effectiveness of semantically defined context management
  • context usage in applications
  • the use of context in the interpretation of ontologies

Whilst the workshop will consider theoretical issues, there will be a particular encouragement for papers relating to practical implementations.
