High Level Modelling of Context of Use

High Level Modelling of Context of Use

• Megan Stewart
• for CS6905

2
What is Context of Use?

• Is not a well-defined concept
• Definition is widely debated
• Means knowing the answers to the W questions
• Context should include both material and social
  circumstances (holistic view)

3
Context and Point of View (1)

• Process-oriented view -- how the information is
  being retrieved

4
Context and Point of View (2)
5
Context and Point of View (3)

• User-oriented view
• Relationship of information to the user

6
Revelation

• Most of the research focuses on management and
  use of context information
• Modelling with an application focus
• Where did the user-oriented view go?

7
Suggestions by Others

• Present definitions are too vague and general
• User-centred empirical attempts
• Combine research of others (User-adaptive
  systems, Context-aware computing)
• Need more research!
