$equation$

Example 46. For two 2-dimensional context instances C = (2010-10-1, New York) and C' = (2010-10-3, New York) in Figure 13.4, the similarity between C and C' is: $equation$

Definition 41. Assume context is an n-dimensional vector (A1, A2, ⋅⋅ ⋅ , An). Let C = (c1, c2, ⋅⋅ ⋅ , cn) and $equation$ be two context instances.

C is equal to C', denoted as C' = C, if and only if ∀i ∈ {1, 2, ⋅⋅ ⋅ , n} $equation$

C is more general than C', denoted as C' ≺ C, if and only if ...
