CawbWeb - The Context-Aware Mobile Web/Cloud
• How do we make developing a context-aware app easy? (and the results reusable)– Specify what you “want” to do in CawbWeb, e.g.
in a series of intentions– Compile these intentions into a working app– Compiler hides details of how to compose Web
services, e.g. WSDL, etc.– [CawbWeb CU Tech Report 2010]
Summary
• Research challenges encountered (and not solved):– What are the important attributes to track?– Group inference and recommendation– Privacy of individuals and groups– How to make building context-aware app’s easy
and reusable?• [email protected]
