With a keyboard and supporting system developed at Cornell University, input methods used to identify ideographs are adaptations of well-known schemes; innovation is in the addition of automatic machine selection of ambiguously identified characters.The unique feature of the Cornell design is that a certain amount of intelligence has been built into the machine. This allows an operator to take advantage of the fact that about 60% of Chinese characters in text are paired with other characters to form two-syllable compounds or phrase words. In speech and writing these pairings eliminate about 95% of the ambiguities created by ambiguously identified syllables.
