Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creation apparatus using a computer, a word processor, etc., and an apparatus and method for checking spelling of words, and particularly to a foreign language that a user (operator) remembers only in a vague manner. TECHNICAL FIELD The present invention relates to a word input support device and a word input support method for supporting input of spelling.

[0002]

2. Description of the Related Art In recent years, there has been an increasing demand for inputting a foreign language in a document preparation device using a computer, a word processor or the like. In such a document creation device that responds to a request, a foreign language corresponding to a word such as kana notation is stored in a dictionary in advance. Then, the foreign language corresponding to the word input by kana is detected from this dictionary and conversion processing or display processing is performed. Furthermore, JP-A-5-28229
The document creation device described in No. 3 has a function of selecting the inflectional form of the detected verb. Also, various devices for checking spelling of words such as English have been developed. These are so-called spell checkers.

Such a spell checker holds in advance the spelling of words in the form of a dictionary, and if a word that does not exist in this dictionary appears in the document to be checked, it is assumed that the word was erroneously entered, and this erroneous entry is made. Is notified to the user. The spell checker also presents the user with words in the dictionary that have spellings similar to the hypothetically mistyped words as candidate words to correct.

At this time, the similarity between the input word and the word in the dictionary is judged on the basis of the spelling character replacement distance. The replacement distance is the number of times that a character change operation necessary to obtain the resulting spelled character from the original spelled character, that is, the operation of replacing a character, deleting a character, or adding a character, is treated as a distance. Is the way. In this method, for example, when inputting the word "lite", the words "line" (one character replacement), "liter" (one character addition), "lit" (one character deletion), etc. Can be listed as a candidate.

Thus, using the spell checker,
Since the above-mentioned words having a short substitution distance are listed as correct word candidates, spelling errors due to typos can be corrected to some extent effectively.

[0006]

In the above-mentioned conventional document creating apparatus, only the correspondence between the kana notation stored in the dictionary and the target foreign language notation is searched. Therefore, the word originally desired by the user is not detected, for example, when the kana notation of the desired word is ambiguous and incorrect. In particular, there are many such problems due to phonological differences between the native language and the foreign language.

Also in the spell checker, the cause of spelling errors is not limited to typos. Spelling mistakes, especially when writing a foreign language, are not just typos,
This is often due to the phonological difference between the user's native language and the foreign language that is being written.

For example, it is generally difficult for a Japanese person to distinguish the pronunciation of "L" from the pronunciation of "R". There are a plurality of English words such as “light”, “right”, and “write” that are written as “light” when they are converted to Japanese katakana notation. When Japanese write English, it is possible that these words are confused and used. If you misspell the English spelling due to the Japanese pronunciation, you may be far from the correct spelling.

Therefore, when trying to write "light", "lit"
If you spelled "e", the conventional spell checker would use "line", "liter", "lit" as described above.
Are listed as candidates for correct words. However, it is difficult to list "light" as a candidate for a correct word because "light", which is originally desired as a candidate, has a long replacement distance from "lite". As described above, the conventional technique has a problem that an appropriate correction candidate cannot be provided when a foreign language is misspelled due to a phonological cause.

Further, in the conventional technique, the processing is executed only for spellings that are not in the dictionary held by the spell checker, and if a spelling of a word different from the intended word is accidentally written, the error will occur. I couldn't guess. For example, there are English words written as "light" in Japanese katakana notation, such as "light", "right", and "write". For example, "write" is misspelled in the meaning of "light". In the case of a mistake, the conventional spell checker cannot point out the possibility of the error.

An object of the present invention is to be able to list correct word candidates even if a foreign language is misspelled due to a phonological cause, and to spell another word by accident. There is provided a word input support device and a word input support method capable of pointing out a possibility that the word is wrong and providing a correct word candidate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First and second embodiments of the present invention will be described below with reference to the drawings. First, a first embodiment of the character input device according to the present invention will be described. Although the present invention is effective between Japanese and any foreign language, the case where the foreign language is English will be described as an example below.

FIG. 1 is a block diagram showing a configuration example of claim 1 of the present invention.

In FIG. 1, reference numeral 1 is an input unit for receiving a character input. When the user inputs characters into the device of the present invention, the input unit 1 is a character input means such as a keyboard. When transmitting a character that has already been input to the device of the present invention, the input unit 1 is means for reading character data that has already been input and stored.

In FIG. 1, reference numeral 2 is a data part corresponding to Japanese notation / foreign language spelling. Here, the possibility of spelling in a foreign language corresponding to Japanese Katakana notation is described in the form of data.

In FIG. 1, 3 is a Japanese notation / foreign language spelling conversion unit. The Japanese spelling / foreign language spelling conversion unit 3 refers to the data stored in the Japanese spelling / foreign language spelling correspondence data 2 to refer to the foreign language word corresponding to the Katakana notation transmitted from the input unit 1. Combine the spelling candidates for.

In FIG. 1, 4 is a foreign language dictionary.
In FIG. 1, 5 is a foreign language word determination unit. This foreign language word determination unit 5 is a Japanese notation / foreign language spelling conversion unit 3.
With the spelling of the foreign language word candidate transmitted from, the heading of the foreign language dictionary 4 is searched to determine the spelling that actually exists as the foreign language word.

In FIG. 1, 6 is a display section. The display unit 6 is a display device such as a display for displaying to the user the foreign language word output from the foreign language word determination unit 5.

FIG. 2 shows one of the two types of data stored in the Japanese notation / foreign language spelling compatible data section.
An example of the contents of the irregular Japanese spelling / foreign spelling irregularity correspondence data portion 21 which is the type is shown. FIG. 3 shows an example of the contents of the Japanese notation / foreign language spelling rule correspondence data part 22, which is another type of the two types of data stored in the Japanese notation / foreign language spelling correspondence data part 22.

The regular correspondence between Japanese katakana notation and foreign language spelling is stored in the Japanese notation / foreign language spelling rule correspondence data section 22. FIG. 3 shows the example. FIG. 3 is in a tabular form and shows that the Japanese spelling in the center column can correspond to the Japanese romanization written in the leftmost column. The rightmost column shows the conditions under which the correspondence holds. For example, in the spelling of English corresponding to the part of the word notation pronounced "ai" in Japanese, that is, the part written as "ai" in Roman letters, "i""igh""ei""eigh"" It can be seen from FIG. 3 that ig ”and“ y ”are possible. It is shown that the English spelling “ig” and “y” can correspond to the Roman character “ai” when the “n” is connected to the back and when it is other than the beginning of the sentence.

The data part 22 corresponding to the Japanese spelling / foreign language spelling rule by correspondence between Japanese katakana spelling and spelling in foreign languages.
The irregular correspondence that cannot be completely described in 1. is described in the Japanese notation / foreign language spelling irregular data section 21. FIG. 2 shows the example.

FIG. 2 is in the form of a table and shows that the English words written in the right column correspond to the Japanese katakana notation in the left column. For example, FIG. 2 shows that the Japanese word "cake" corresponds to the Japanese katakana "cake". When "cake" is regularly applied to the pronunciation of Japanese, it is "cake" or "cake", but the word "cake" is historically called "cake" in Japanese. Since it does not apply to regular correspondence, it must be held as irregular correspondence data. This is an example of historical and customary irregular correspondence between the pronunciation of the original foreign language and the pronunciation in Japanese (Roman character notation). Data of other irregularly-corresponding words are also stored in the section 21.

The Japanese "questionnaire" originates from French and corresponds to the word "questionnaire" in English. Language you want to get like this (English in this case)
If pronunciations originating in languages other than Japanese are standardized in Japanese, the correspondence is stored as irregular data. The food described as "bread" in Japanese is "bread" in English, but this is a similar example. "Nighter", which means a game played at night in Japanese, is expressed as "night game" in English. Such Japanese English is also stored as irregular data.

Next, the operation of the first embodiment will be described with reference to FIG. First, a word (character) written in katakana is input to the input unit 1 (step S1). The input word in katakana notation is converted into roman character notation in the Japanese notation / foreign language spelling conversion unit 3 (step S2). Further, the corresponding foreign language notation is synthesized using the katakana notation and the Roman alphabet notation of the input word (step S3). In addition to this, a search process for the irregular Japanese spelling / foreign language spelling irregularity data section 21 is also executed.
After that, it is determined whether or not the synthesized / detected characters are stored in the foreign language dictionary 4, and the stored words are displayed on the display unit 6 (steps S4, 5).

Next, the operation of the first embodiment will be described using a concrete example. First, assume that a Japanese is writing English and uses the foreign language spelling confirmation device of the present invention.
This Japanese user uses the word "ligh" which means "light".
Suppose you didn't clearly remember the spelling of "t". At this time, this user inputs "light" and katakana into the foreign language spelling confirmation device of the present invention.

The inputted katakana "light" is transmitted to the Japanese notation / foreign language spelling converter 3. The Japanese notation / foreign language spelling conversion unit 3 first converts the input Katakana into Roman characters for later processing. The Roman letters in this case are based on the Hepburn system, but in the Hepbon system, the Japanese vowel longs are not clearly displayed, so the vowel longs are "aa" and "e" in the case of "a". If "ii",
"Uu" for "woo", "ee" for "a", and "oo" for "oh". In the case of "light" in the present example, the Roman character "raito" is obtained.

Next, the Japanese notation / foreign language spelling conversion unit 3
Refers to the data stored in the Japanese notation / foreign language spelling correspondence data section 2 and synthesizes the katakana notation of "light" and the corresponding foreign language notation of "raito" in Roman alphabet.

The katakana notation of "light" is used to search the data part 21 corresponding to irregular spelling in Japanese / foreign language. In the case of this example, it is assumed that the irregular correspondence data is not found. Next, the Japanese notation / foreign language spelling rule correspondence data section 22 is searched for in the Roman character notation “raito”.

The search method is as follows. First of all, the Japanese notation / foreign language spelling rule corresponding data section 22 is searched for in the entire Romanized notation. There is no data for the entire Romanization. In that case, one character is deleted from the end of the Roman alphabet, and the Katakana / foreign language rule correspondence data part 22 is searched for with the character string. It is assumed that there is no data for this character string. This operation of deleting one character at the end is repeated until data is present.

In the case of the previous example of "raito", if the katakana / foreign language rule correspondence data part 22 is searched for with the character "r" at the beginning, the spelling of the corresponding English words from FIG. 3 is "r""l". It turns out that there can be "rr", "ll", "wr", etc. Next, delete "r" from the entire character string and repeat the previous operation for the remaining character string "aito". That is, the katakana / foreign language rule correspondence data portion 22 is searched for “aito”. It is assumed that there is no data for this character string.

Next, one character is deleted from the end of this character string and a search is performed. Repeat this. Then, it can be seen from FIG. 3 that data is present when searching with the character string “ai” and corresponds to the English spellings “i”, “igh”, “ei”, “eigh”, “ig”, “y” and the like. Similarly, the above operation is repeated for the entire spelling "raito". Then, the roman letter "r"
A plurality of English spelling candidates that can correspond to "ai", "t", and "o" are obtained. This example is shown in FIG.

The Japanese spelling / foreign language spelling conversion unit 3 combines the English spelling candidates corresponding to the inputted partial character string in Roman spelling to synthesize the spelling of English word candidates for the entire Roman spelling. In this example, "r""ai""t"
The English spelling candidate corresponding to "o" is combined to "rait
Synthesizes the English word spelling candidates for the entire romanization of "o". As a result "rite""right""reite"
"Lytto""light""write""wrytto""wreightte"
And so on. The foreign language word determination unit 5 searches the foreign language dictionary 4 for a headline and determines whether these candidate spellings exist as actual English words. In this example, the English dictionary is used as the foreign language dictionary 4. Of the spellings obtained as English word candidates, "rite" and "ri" appear in the actual English dictionary.
Since it is found that "ght", "light", "write", etc. exist, the result is transmitted to the display unit 6. The display unit 6 displays the English word to the user.

As a result, the user selects "rite" and "righ" as the English words for the input katakana "light".
You can see that there are "t", "light", "write", etc. When a word is actually found by searching the English dictionary, not only the spelling but also its semantic information can be extracted and displayed together with the spelling. When the semantic information is displayed in this way, when there are a plurality of English words corresponding to the katakana notation as in this example, it is useful for the user to correctly select the target word from the words.

Similarly, the case where the katakana "pan" is input will be taken as an example. In this case, there is data also in the Japanese notation / foreign language irregularity correspondence data portion 21, and the spelling of the English word "bread" is obtained. From the Japanese notation / foreign language spelling rule correspondence data part 22, the steps like “pan”, “pun”, “pon”, “pann”, “pam”, and “pamm” are spelled as word candidates in the same procedure as in the previous example. It is obtained (see FIG. 5B for English spelling candidates). The foreign language word determination unit 5 searches the foreign language dictionary 4 for all of these to determine whether or not the word actually exists, and as a result, the existing word "brea
Display "d", "pan", "pun", etc. to the user. that time,
If you extract the meaning from the dictionary and display it along with the spelling, it will be useful for selecting words.

Next, a second embodiment of the word input support device according to the present invention will be described. FIG. 6 is a block diagram showing a configuration example of claim 2 of the present invention. In FIG. 6, reference numerals 1, 2, 3, 4, 5 and 6 are the input section, the Japanese writing / foreign language spelling compatible data section, and the Japanese writing / foreign language spelling conversion section, respectively, as in FIG. , Foreign language dictionary,
The foreign language word determination unit and the display unit. In FIG. 6, 7 is a data section corresponding to foreign language spelling and Japanese notation. Here, knowledge of Japanese notation corresponding to spelling in foreign languages is stored in the form of data. Reference numeral 8 denotes a foreign language spelling / Japanese notation conversion unit. The foreign language spelling / Japanese notation conversion unit 8 obtains the Japanese notation corresponding to the input foreign language spelling by referring to the foreign language spelling / Japanese notation correspondence data unit 7.

In the case of English, a method as described in Japanese Patent Publication No. 6-68746 is a method for obtaining the notation in Japanese in which the pronunciation is associated with the pronunciation of Japanese from the spelling of English words. Since it is known that it can be adopted, it will be described below with reference to FIG. FIG. 7 is a table showing an example of data stored in the foreign language spelling / Japanese writing correspondence data unit 7. The leftmost column shows the spellings that make up the English word. The second column from the left shows the pronunciations that English words can have. In the third column from the left, the possibility of writing the pronunciation of the spelling in Japanese is written in Roman letters. In this case, the romanization is a notation that clearly indicates the long vowel sound based on the Hepburn formula as described above.

Next, the operation of the first embodiment will be described with reference to FIG. First, a word written in a foreign language is input to the input unit 1 (step S11). Characters written in katakana are synthesized from the input characters (step S12). The synthesized katakana notation is used and the corresponding foreign language notation is synthesized (step 13). In addition to this, the data part 21 corresponding to irregular Japanese spelling and foreign language spelling
The search process of is also executed. Thereafter, it is determined whether or not the combined / detected character is stored in the foreign language dictionary 4, and the stored word is displayed on the display unit 6 (steps S14 and 15).

The operation of the second embodiment will be described below with a specific example. Now, assume that the foreign language spelling confirmation device of the present invention is used when the Japanese is writing English and cannot clearly remember the spelling of the English word "light" which means "light". This Japanese user uses the spelling "rite" that seems to be the intended English word based on the pronunciation "light" as a clue.
Enter. The foreign language spelling / Japanese notation changing unit 8 that has obtained the spelling “rite” refers to the foreign language spelling / Japanese notation correspondence data unit 7 and writes the Japanese notation corresponding to the spelling “rite”. obtain.

The procedure is as follows. First, "rit
"e" is searched for the foreign language spelling / Japanese notation compatible data section 7. There is no data for this entire spelling. In that case, the search is performed again with the spelling with one character deleted from the end. In this example, search by "rit". This operation is repeated until the data is found in the part 7 corresponding to the spelling of the foreign language and the Japanese notation. In the case of the present example, according to FIG. 7, the data exists for the first character string “r”. By repeating this operation, data written in Japanese can be obtained for units of spelling English words “r”, “i”, “t”, and “e”. The foreign language spelling / Japanese notation conversion unit 8 combines the Japanese notation data obtained for each part of the spelling and synthesizes the Japanese notation for the entire input spelling. In our case,
The Japanese notation data for the units of spelling English words “r”, “i”, “t”, and “e” are combined to synthesize candidates for Japanese notation for the entire “rite”.

FIG. 9 shows the method of this combination. As a result, when the pronunciation of "rite" is expressed in the Japanese pronunciation system, the Japanese notation is: "rite" (lite), "raite" (write), "raitii" (write), "raito" ( Light) and so on. The result is transmitted to the Japanese writing / foreign language spelling conversion unit 3. The Japanese notation / foreign language spelling conversion unit 3 refers to the Japanese notation / foreign language spelling correspondence data unit and synthesizes the English notation corresponding to each of these Japanese notations. In our case,
As a spelling of an English word candidate having a pronunciation written in Japanese as "rite", "litte" and "wryte" can be obtained. “Rite” (right) and “rei” are candidates for spelling English words that have the pronunciation “raito” (light) in Japanese.
te, lytto, light, write, wrytto, wreight
te ”and so on.

Upon receiving the spelling of the word candidates thus obtained, the foreign language word determination unit 5 searches the heading of the foreign language dictionary 4 to determine whether or not these candidates actually exist as words. To do. In the case of the present example, the heading of the English dictionary is searched, and it is found that the words “rite”, “right”, “light”, “write”, etc., which are pronounced as “light” in Japanese, actually exist. These spellings are transmitted to the display unit and displayed to the user on the display unit. When searching the dictionary
Not only the spelling but also its meaning can be taken out from the dictionary, transmitted to the display unit, and displayed together with the spelling. Doing so helps the user in selecting the correct word.

In this way, the user who spells "rite" as the English word meaning "light" has the same pronunciation as "light" when the pronunciation of this spelling is written in Japanese. You can get a flock. In our case,
"Rite" (ceremony), "right" (right, correct), "ligh
Since “t” (light, light), “write”, etc. are displayed, the user can select the spelling “light” of the target word having the meaning of “light”. In the case of this example, there is a spelling word "rite" input by the user, but according to the present invention, even in such a case, another word similar to the case where the pronunciation is written in Japanese is written. can do. The conventional spell checker is designed to display correct word spelling candidates only when a word that is not in the dictionary is entered, so I accidentally entered another word spelling as in this example. In some cases, he pointed out the possibility of the mistake and could not show the correct word spelling candidate. The present invention has such advantages.

[0055]

According to the present invention, when writing a word in a foreign language whose spelling is not clear, the pronunciation can be input in katakana to obtain the desired spelling of the word. Conventionally, for foreign words with unclear spelling, the user generally had to synthesize spelling possibilities one by one and check the dictionary one by one. The time required for can be greatly reduced. Further, according to the present invention, even if the spelling written by the user is another word similar in pronunciation to the word intended by the user, it can be pointed out that the spelling may be incorrect. In the past, there was no way to point out the possibility of mistakes when accidentally writing another word, but the present invention makes it possible to reduce this type of spelling error.

There determination means whether it is stored as a word in the foreign language dictionary <br/>, display means for displaying the character string is determined to be stored as a word in the foreign language dictionary by the determining means, A word input support device comprising: 3. The foreign language dictionary includes words in the foreign language and
Stores the meaning of the word, The display means displays the foreign language dictionary by the determination means.
The character string determined to be stored as a word and the relevant
Display the meaning of words, The word input support according to claim 1 or 2, characterized in that
apparatus. 4. Words in katakana notation and characters in the foreign language
Entered based on the information in which the columns and
To detect the character string corresponding to the specified katakana word.
Steps and entered Katakana words are converted to Roman words
Based on the phoneme-based information that associates the step of decomposing into substrings after conversion, the spelling in Japanese Romanization, and the spelling in the desired foreign language into substrings <br /> Generating a character string by combining spelling of a foreign language corresponding to the generated character string, determining whether the generated character string exists as a word in the foreign language, and the foreign language And a step of displaying a character string determined to exist as a word in 1. in the word input support method. 5. A first decomposing step of decomposing an input foreign language character string into partial character strings , a desired spelling of a foreign language expression and a spelling of a Japanese roman character expression are associated based on phonemes. According to the information, the first
A first generation step of generating a character string by combining spellings in Japanese Roman letters corresponding to the partial character strings decomposed by the decomposition step; and decomposing the character string generated by the first generation step into pronunciation units. The second decomposition step, the spelling of the Roman notation in Japanese, and the spelling of the desired foreign language are associated with each other based on the phoneme, and the foreign language corresponding to the partial character string decomposed by the second decomposition step. A second generation step of generating a character string by combining the spellings of, a step of determining whether the character string generated by the second generation step exists as a word in the foreign language, and the foreign language And a step of displaying a character string determined to be present as a word, the word input support method comprising: 6. The step of displaying is in the foreign language.
A character string that is determined to exist as a
Display the meaning of words, The word input support according to claim 4 or 5, characterized in that
Method.
