For example, the IC M between "康斯 坦茨湖" and "Constance Lake" is [康斯坦茨, Constance, TL] and [湖, Lake, TS], so its associated mapping type ratio will be "0.5" (i.e., 1/2).
the internal mapping is further deduced by introducing the internal mapping type Mtype and the mapping type ratio  as follows:  In the above equation, the mappings between internal components are trained from the syllable/word alignment of NE pairs of different NE types.
