Refining Topological Relations between Regions Considering Their Shapes
Topological relations are sometimes insufficient for differentiating spatial configurations of two objects with critical difference in their connection styles. In this paper, we pr...

Splitting Ratios: Metric Details of Topological Line-Line Relations
Within the geographic domain, an important class of relies on geometric abstractions in the form of lines where, for instance, transportation networks and trajectories of movement...

Mining Topological Relations from the Web
Topological relations between geographic regions are of interest in many applications. When the exact boundaries of regions are not available, such relations can be established by...

Topological Relations of Arrow Symbols in Complex Diagrams
Illustrating a dynamic process with an arrow-containing diagram is a widespread convention in people's daily communications. In order to build a basis for capturing the struct...

Topological Consistency for Collapse Operation in Multi-scale Databases
When we derive multi-scale databases from a source spatial database, the geometries and topological relations, which are a kind of constraints defined explicitly or implicitly in ...

Three-Valued 9-Intersection for Deriving Possible Topological Relations from Incomplete Observations
Topological relations, which concern how two objects intersect, are one of the most fundamental and well-studied spatial relations. Typically, topological relations are distinguis...
