Mereological relationships--relationships between parts and wholes--are essential for ontological engineering in the anatomical domain. We propose a knowledge engineering approach that emulates mereological reasoning by taxonomic reasoning based on SEP triplets, a special data structure for the encoding of part-whole relations, which is fully embedded in the formal framework of ...
