Conclusions

  • Context cannot be separated from its use

  • Context makes reasoning local

  • Context guides the focus of attention

  • Context and knowledge are close

  • Expert knowledge and reasoning always occur within a context

  • Context should be represented explicitly

  • Many different formalisms and approaches:

    Logic , Rules, Frames/Schemas, Conceptual Graphs, Contextual Graphs

  • Pros and cons for each – choice depends partly on system's other knowledge representation


    Context: The Future

  • Research in context will continue its dramatic growth & importance of Context

  • Future will see more context-aware and context-sensitive agents, programs, and appliances

  • Context in multiagent systems: cooperative as well as competitive (e.g., on the Web):

    - shared context
    - discussing context
    - reasoning about own, others' context
