Abstract: A method and apparatus for determining at least one of a character and a destination therefor in accordance with a received signal representing at least one of a plurality of characters and at least one character corresponding to at least one of a plurality of languages. Likelihood values for at least one of plurality of characters and each of the languages are evaluated, and at least one of the plurality of characters and one of the character languages are selected in accordance with the evaluated likelihood values thereof.

Abstract: An information processing equipment providing easy operations of changing-over character species, and, in which characters can be entered without being conscious of the designation of a character mode. Signals entered from an input device are handled in conformity with all of a romaji (Roman character) input system, a kana (Japanese syllabary) input system and an alphanumeric input system. Results obtained with the respective input systems are all displayed in the predetermined part of a display screen. In the equipment, the character mode intended by a user is estimated as to the entered character string, and is automatically selected. In another aspect of performance, a controller determines whether or not a character mode likelihood decision unit and a character code translation unit are started, in accordance with the results of the comparisons between the key code string and the registered contents of a learning information buffer.
