Abstract

An unambiguous bidirectional transliteration system is provided. A look-up table having a unique and unambiguous correspondence between individual Korean language vowels and Korean language consonants, and one or more characters of English language is implemented into the computerized transliteration system. The table is constructed to assure phonetic fidelity between pronunciation of the individual syllables of Korean language and the syllables of English language. The system can unambiguously covert Korean syllables into corresponding English syllables based on the look-up table and can unambiguously convert the English syllables into Korean syllables based on the look-up table. A Hangul input method and Hangul input system are provided based on this bidirectional transliteration system.

a microprocessor coupled to said input device, said storage medium, and a monitor, said microprocessor converting the inputted at least one English syllable into a corresponding Korean syllable in accordance with said lookup table; and

said monitor displaying the inputted at least one English syllable and the converted Korean syllable.

2. The transliteration system of claim 1, wherein said input device is a keyboard and said microprocessor converts each said inputted English syllable into a corresponding Korean syllable in accordance with said look up table when a space key on said key board is depressed after each said English syllable is inputted.

3. The transliteration system of claim 1, wherein said microprocessor converts a portion of the inputted at least one English syllable into a corresponding Korean syllable in accordance with said look up table when a user selects the portion among said inputted at least one English syllable and executes a transliteration command.

4. The transliteration system of claim 1, wherein said microprocessor is able to reconvert the converted Korean syllable into said at least one English syllable in accordance with said look up table.

5. A transliteration system, comprising:

an input device inputting at least one Korean syllable into said transliteration system;

a storage medium storing said at least one Korean syllable;

a lookup table stored in said transliteration system, said look up table showing a correspondence between individual Hangul letters and individual sets of English characters, each set comprising at least one English character, wherein assigned to G, assigned to N, assigned to D, assigned to R when is an initial consonant, assigned to L when is a final consonant, assigned to M, assigned to B, assigned to S, assigned to none when is an initial letter of a Korean syllable, assigned to NG when is the final letter of a Korean syllable, assigned to J, assigned to CH, assigned to K, assigned to T, assigned to P, assigned to H, assigned to A, assigned to YA, assigned to U, assigned to YU, assigned to O, assigned to YO, assigned to OO, assigned to YOO, assigned to EU, assigned to I, assigned to AE, assigned to YAE, assigned to E, assigned to YE, assigned to WA, assigned to WAE, assigned to OE, assigned to WO, assigned to WE, assigned to WI, and assigned to UI;

a microprocessor coupled to said input device, said storage medium, and a monitor, said microprocessor converting the inputted at least one Korean syllable into a corresponding English syllable in accordance with said lookup table; and

said monitor displaying the inputted at least one Korean syllable and the transliterated set of English characters.

6. The transliteration system of claim 5, wherein, when a user selects a portion of the inputted at least one Korean syllable and executes a transliteration command, said microprocessor converts the selected portion into the corresponding English syllable in accordance with said lookup table.

7. The transliteration system of claim 5, wherein said microprocessor displays the converted English syllables separated by spaces after the Korean syllables are inputted and converted.

8. The transliteration system of claim 5, wherein said storage medium stores the converted English syllable.

9. The transliteration system of claim 5, wherein said microprocessor reconverts the converted English syllable into the at least one Korean syllable in accordance with said look up table.

10. A method for generating a Korean syllable in a computer by inputting an English syllable, the method comprising the steps of:

providing the computer with a lookup table, said look up table showing a unique and unambiguous correspondence between individual Hangul letters and individual sets of English characters, each set comprising at least one English character;

inputting the English syllable into the computer;

depressing a space key right after each English syllable is inputted;

executing a transliteration from the inputted English syllable to the corresponding Korean syllable in accordance with said lookup table after the depressing step; and

generating the Korean syllable by replacing the inputted English syllable with the corresponding Korean syllable,

wherein said lookup table shows a correspondence between individual Hangul letters and individual sets of English characters, each set comprising at least one English character, wherein assigned to G, assigned to N, assigned to D, assigned to R when is an initial consonant, assigned to L when is a final consonant, assigned to M, B, assigned to S, assigned to none when is an initial letter of a Korean syllable, assigned to NG when is the final letter of a Korean syllable, assigned to J, assigned to CH, assigned to K, assigned to T, assigned to P, assigned to H, assigned to A, assigned to YA, assigned to U, assigned to YU, assigned to O, assigned to YO, to assigned to OO, assigned to YOO, assigned to EU, assigned to I, assigned to AE, assigned to YAE, assigned to E, assigned to YE, assigned to WA, assigned to WAE, assigned to OE, assigned to WO, assigned to WE, assigned to WI, and assigned to UI.

11. A method for converting English syllables into Korean syllables in a computer, the method comprising the steps of;

providing the computer with a lookup table, said look up table showing a unique and unambiguous correspondence between individual Hangul letters and individual sets of English characters, each set comprising at least one English characters;
