In order to address problems of information overload in digital
imagery task domains we have developed an interactive approach to the
capture and reuse of image context information. Our framework models
different aspects of the relationship between images and domain tasks
they support by monitoring the interactive manipulation and annotation
of task-relevant imagery. The approach allows us to gauge a measure of
a user's intentions as they complete goal-directed image tasks. As
users analyze retrieved imagery their interactions are captured and an
expert task context is dynamically constructed. This human expertise,
proficiency, and knowledge can then be leveraged to support other
users in carrying out similar domain tasks. We have applied our
techniques to two multimedia retrieval applications for two different
image domains, namely the geo-spatial and medical imagery domains.
