Description

How to input and restore Korean characters using Roman characters

The present invention relates to a method for inputting and restoring Korean characters so that Korean characters can be represented only in Roman characters and roman characters written in Roman characters can be correctly restored without errors in the Hangul / Roman automatic conversion system.

There are two general methods of expressing Korean characters in Roman letters: the sperm method (in the Ministry of Education in 1969) to write Korean words (i.e. phonemes) in letter order, and when the Romans read English or Americans. There was a way of writing down the phonetic sounds (ie, phonetic principles, notation lyshower notation).

However, the common problems of this sperm method and the Mycoccus lyshower notation are as follows.

First, because it doesn't represent a non-sounding "yieun", it is not possible to know whether the consonant corresponds to the first syllable or the next syllable when you write it in Roman letters, so you can restore the roman letters back to Korean. There was no. For example, "hangang" could not distinguish between "Hangang" or "hang".

Second, because it did not display syllables, it was not possible to restore Korean characters that were represented in Roman letters back to Korean. For example, "hamira" could not distinguish between "hamira" or "hamira."

Third, when the support of Hangul is expressed in Roman letters, the support of "c", "ㅅ", and "ㅆ" are all expressed as "d", and the meaning of "ㄱ", "ㄲ", "ㅋ", and "의" Since the base was expressed as "g" or "k", the original text was not distinguished when the Roman letters were restored to Korean. In particular, it is almost impossible to restore the original Hangul from the Roman alphabet because the conventional method according to the headless shower shower notation is written in a phonetic manner, and if the shoulder point (') and vandal point (˘) are omitted It was more impossible to restore as it was. In addition, the keyboard has a problem that is difficult to express because many do not have a half moon.

The present invention has been made to solve the problems described above, in the Hangul / Roman automatic conversion system, without the mechanical means for expressing Hangul to represent Hangul only one-to-one correspondence to Hangul, and Hangul written in Roman alphabet without errors It is an object of the present invention to provide a Hangul input and restoration method to accurately restore only one, and a computer-readable recording medium recording a program for realizing the same.

To provide.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of a Hangul / Roman automatic conversion system to which the present invention is applied.

In the Hangul / Roman automatic conversion system to which the present invention is applied, when Hangul is inputted to the input device 11, the Hangul is converted from the output device 15 to Roman characters and outputted. In (15), the roman characters are converted to Hangul and output.

The input device 11 is a device in which Korean or Roman characters are input. However, in the case where Roman characters are input, the present embodiment is based on the premise that input is performed according to the Hangul input process by the Roman characters described later.

The Hangul / Roman Converter 12 implements a Hangul autometa for the Korean consonants and vowels that correspond to Roman characters in software or hardware. Do this.

The main memory device 13 temporarily stores and stores Hangul or Roman characters to be converted by the Hangul / Roman converter 12 to process them in real time. For example, it acts as the main memory of the computer.

The auxiliary memory device 14 serves to store the entire input Hangul or Roman characters. For example, it acts like a computer's hard disk.

Now, the method of representing Hangeul and Roman letters in a one-to-one correspondence will be explained in more detail.

In order to achieve complete interconversion from Roman to Korean or from Hangul to Roman, the following principles must be observed in order to display Hangul in Roman letters.

First, "yi" in front of an unvoiced vowel is always represented as a symbol or Roman (eg, ',',-, x). Here, omission may be allowed if the beginning of a word begins with a vowel. That is, by expressing "a'i" in which the Hangul "i" should be represented as "a'i" in the Roman alphabet, it is possible to allow the omission of "Ie-eun" that is not sounded.

Second, to distinguish syllables, the symbols (ie syllables) representing syllables by Roman characters must be recorded (ie, ',',-, x). However, the syllable symbol may be omitted if the syllable is broken by the Korean autometa used in the existing word processor. Here, "yieun (ㅇ)" and "syllable symbol" that do not sound in front of the vowel may be the same.

Third, vowels and consonants must correspond to one set of Roman letters or combinations of letters. However, if there is no confusion with other Hangul consonants or vowels, one Hangul consonant or vowel is allowed to correspond to a combination of plural Roman characters (e.g. expressing "ㅊ" as "c, ch, q" May be allowed).

For example, the initial consonant, the neutral, and the final consonant of Hangeul are written as a single word (ie phoneme). In other words, the first, middle, final, syllable, syllable, short vowel, and vowel vowels of Hangeul are exactly one-to-one correspondence with Hangeul.

As described above, the notation by Roman letters corresponding one-to-one to the consonants and vowels of the Hangul for writing the Hangul alphabet is shown in (Table 1) and (Table 2).

(Table 1) shows the Roman letters that correspond one-to-one to the Hangul consonants. In the case of "ㄹ" in Table 1, "r" or "l" can be indicated. You can also limit yourself to writing with "l" only. In addition, in the case of "ch", it is also possible to limit the use of only one of "ch", "c" or "q", or to mix both or both.

In the case of "ㅇ", when it is pronounced, it is expressed as "ng", and when it is not pronounced, it selects one of "x, ',',-", or mixes some or all of them. Can be allowed to use.

(Table 2) shows the roman letters that correspond to Korean vowels one-to-one, and the vowels that start with "TT" are denoted by "w". Also, compulsory division of syllables is made by syllable symbols (', x,-,').

Referring to (Table 1) and (Table 2) as described above will be described in detail how to write the Hangul alphabet. In this example, both syllables and non-sounding responses are given as "'".

For example, "to die, to the Lord, to die" is written as "jug'gena, ju'ggena, jug'ggena".

"Wipe, shut, wipe" is written as "daggda, dagda, daggdda".

"Gogo para gogogo play alone when young" is written "gagopara gagopa 'eoril ddai honja nol deon".

"Upper" is written "wis'saram".

"Gungye County" is written as "gung'ye gun'gye".

On the other hand, when the omission is allowed, the omission of the roman or symbol corresponding to the non-sounding response may be allowed at the beginning of the next word. In this case, the non-sounding response is represented by the symbol "'".

For example, "e'i 'i' o'i" is written "e'i i o'i".

Between "i" and "y" breaks the syllable and allows the omission of the Roman notation (x) or the symbol (',',-) that corresponds to the silent response.

For example, "yiyang" is written "iyang" (in principle 'i'yang).

"Iang" is written as "i'ang (or iang)".

And, "u" and "i" allow the omission of the symbol corresponding to the non-sounding response breaking the syllable.

For example, "위동 우이동" is written "widong, uidong".

As another embodiment, "cheongju, jeonju, jeongju" is written as "cheongju, jeonju, jeongju".

"Mother came to school" is written as "'eomeoniga hag'gyo'e' osyeoss'seubnida."

"There are chickens in the chicken coop" is written as "dalgjang'eneun dalgdeul'i 'isseubnida."

"Gogo para gogogo playing alone when young" is written "gagopara gagopa 'eorilddai honja nol deon".

"Life deceives you" is written as "salm'i dangsin'eul sog'il jirado".

2 is a flowchart illustrating a Hangul input method using Roman characters according to the present invention.

As shown in FIG. 2, the Hangul input method using Roman characters according to the present invention first reads Hangul one by one syllable (201) and analyzes whether there are syllables already converted to Roman characters (202).

As a result of the analysis, if there are already syllables converted to Roman characters, it is checked whether syllable symbol insertion is necessary (203).

As a result of the test, if syllable symbols need to be inserted, a symbol corresponding to a syllable symbol is inserted between the front syllable and the back syllable (204), and then converted into a corresponding Roman letter (205). At this time, if it is decided to omit the "o" that does not sound at the beginning of the word, it is omitted. In this case, when all syllable symbols are to be inserted, the syllable is inserted unconditionally at the end of the syllable. Otherwise, the following case is applied.

In case of automatic conversion by Hangul automata, don't input syllable symbol. For example, in the case of "galmu", "ㄹ" and "ㅁ" are not automatically inserted between "gal" and "mu" because syllables are automatically separated in Korean automata. That is, it becomes "galmu".

Then, if the last syllable is "o" and the later syllable starts with "a", the syllable is inserted after converting the syllable from the first syllable to roman (ie, "ng"). . That is, in the case of "gangga", "gang'ga" is written.

On the other hand, when syllables are not automatically divided by the Hangul automata, syllable symbols are inserted. For example, if the last syllable is "a", "c", or "s", the syllable may be given a syllable even when the first syllable meets the same type as "a", "c", or "s". Insert it. This is to avoid confusion with "ㄲ", "ㄸ" or "ㅆ", respectively.

If there are no syllables already converted to Roman characters or if syllable symbol insertion is not necessary, the characters are directly converted to the corresponding Roman characters (205).

Finally, it is determined whether there is a Hangul to read further (206), if there is no Hangul to read further, and if there is a Hangul to read further, the Hangul is read by one syllable (201) and again the roman conversion process (202 to 205) is repeated. To perform.

3 is a flowchart illustrating an embodiment of a Hangul restoration method using Roman characters according to the present invention.

As shown in FIG. 3, the Hangul restoration method according to the present invention first reads Roman characters one letter at a time 301 and analyzes whether the sound is "O" or vowels (302).

As a result of the analysis, if there is no sound or "vo" without a vowel, the syllable is divided (303). If there is no sound or "vo" or vowel, the next one of the Roman letters is read (301) to see if the syllable is divided. Inspect (303). Here, when the next character is temporarily read from a buffer or the like and the character is divided into syllables by a syllable symbol or a Korean automata used in a Korean word processor, it is considered to be divided into syllables. Also, syllables are considered to be broken even if there is no next letter to read.

As a result of the test, when the syllable is divided, the syllable is already stored or output except the one letter read to check whether the syllable is divided (304).

If the sound is "o" or vowel or the syllable is not divided, it reads the roman letters one by one (301) and analyzes whether the sound is "o" or vowel (302).

Finally, determine if there are more Roman characters to read (305), and quit if there are no Roman characters to read, and read the Roman characters one by one if there are more Roman characters to read (301). 302 to 304) are repeated.

According to the present invention as described above, by fully matching the Hangul and Roman alphabet one-to-one, it is possible to accurately information by the Roman alphabet of the Hangul. Thus, the social, economic and cultural costs of the field in which this notation is used can be saved.

For example, when using such a notation, the present invention needs to accurately represent the notation of Korean in books such as papers (eg, "duck, dag, dagg" as "duck, dag, dagg"). It can be used, and if there is no Korean keyboard or if the terminal does not have Korean font installed and sends an e-mail to the English keyboard, it can be perfectly received in the Korean language. In addition, the present invention, even if there is only an English keyboard, it is possible to completely write Hangul in Roman letters, and it is possible to express Korean names on road signs so that they correspond one-to-one with Hangeul. It can be used when creating.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

As described above, the present invention can express all Korean characters only with Roman characters without mechanical means for expressing Korean characters, and can accurately restore them without errors, thereby reducing the cost of installing Korean software, and have Hangul and Roman characters one-to-one. By fully responding to this, accurate informatization by Hangul's Roman letters is possible, which has the effect of reducing social, economic and cultural expenses.
