Semantic Integration
Design: Define a common view of information
- Simple Concepts: price ($), weight (oz), resolution (pixels), …
- Composite Concepts: good laptop, bargain, sub-notebook, …
Configuration: Describe each source
- What information it can provide
- How its data is mapped to the common view
Execution: Automatic Integration:
- Unfold definitions of composite concepts
“Good laptop = laptop & recommended by CNet”
“Bargain = price less than $1000”
- Choose sources for simple concepts
- Dynamically execute plan: “join” and “union” information
