“…And the most important model in RCC is the RCC-8, which represents 8 kinds of RCC relationships, i.e., {DC, EC, EQ, NTPP, NTPPi, TPP, TPPi, PO}, and the corresponding semantics are disjoint, meet, equal, contains, inside, covers, coveredby, and overlap, respectively. Currently, the most widely used model for analyzing topological relations is a 9-intersection model, which is based on the intersection between the parts (interior, boundary, exterior) of crisp spatial objects [28]. For two crisp spatial objects A and B, let A 0 , ∂A, A -be the interior, boundary, and exterior of A, respectively.…”
