Abstract:     Phonetic Chinese (Pinyin and BPMF) is entered into a computer system and accurately converted into the Hanzi form. The system has a novel keyboard with diacritic keys (and corresponding ASCII coding) that permit the user to annotate each entered phonetic text syllable with a diacritic that indicates the tone of the syllable. A process executing on the system determines that a syllable has been entered when a diacritic (or delimiter) key is struck. An entered phonetic syllable is then compared to a list of acceptable phonetic syllables and abbreviations. If the entered syllable is on the list, the correctly spelled and accented syllable is stored in memory and displayed on a phonetic portion of a graphical display. The process continues for succeeding syllables until a delimiter is entered. Upon encountering a delimiter, the word string (defined as the string of characters between two delimiters) is analyzed using morphological and syntactical processes and/or a statistical language model to unambiguously determine the proper Hanzi characters that represent the word(s) in the word string. The unique Hanzi translation is stored in memory and displayed on a Hanzi portion of the graphical interface.

First Claim:
Show all 14 claims
I claim:     1. A computer system for processing Chinese language text comprising:
  • a computer memory;
  • an input apparatus for entering a plurality of Chinese phonetic language syllables into the system, each syllable having one or more characters, the input apparatus marking one or more of the accented syllables with diacritic that indicates a tone of the accented syllable;
  • an input unit that provides a character code for each character and a tone code for each diacritic entered by the input apparatus, the input unit recognizing a syllable as a string of character codes marked by tone code;
  • a syllable list having a plurality of syllable strings, each syllable string being associated with one or more syllable string codes, the input unit matching the string of character codes marked by the diacritic code to one of the syllable string codes and storing in the computer memory a syllable representation for the syllable string associated with the syllable string code that matches the string of character codes marked by the tone code.
