org.aksw.limes.core.measures.mapper.topology.RCC8.LDbasedRCC

public class LDbasedRCC
extends Object

inspired by the paper "Radon — Rapid Discovery of Topological Relations" by the authors: Mohamed Ahmed Sherif, Kevin Dreßler, Panayiotis Smeros, Axel-Cyrille Ngonga Ngomo and some of code reused from the original implementation of RADON by Kevin Dreßler. in this implementation, we use qualitative spatial representation and reasoning (mainly RCC8) instead of the Dimensionally Extended nine-Intersection Model (DE-9IM)
