Example: Spatial Association Rule Mining
“What kinds of spatial objects are close to each other in B.C.?”
- Kinds of objects: cities, water, forests, USA_boundary, mines, etc.
- is_a(x, large_town) ^ intersect(x, highway) ® adjacent_to(x, water). [7%, 85%]
- is_a(x, large_town) ^adjacent_to(x, georgia_strait) ® close_to(x, u.s.a.). [1%, 78%]
Mining method: Apriori + multi-level association + geo- spatial algorithms (from rough to high precision).
