A Hybrid Reasoning Model for “Whole and Part” Cardinal Direction Relations
Table 2
(a) Composition of binary relations in the -direction for the hybrid model (composed relations of {WN} and {WN,H}). (b) Composition of binary relations in the -direction for the hybrid model (composed relations of {H} and {WN,H}). (c) Composition of binary relations in the -direction for the hybrid model (composed relations of {S} and {WN,H}). (d) Composition of binary relations in the -direction for the hybrid model (composed relations of {WN,H,S} and {WS}).
