Description

[Detailed Description of the Invention] [Industrial Field of Application J This invention is a document creation device that converts a hiragana (Roman alphabet) character string inputted from an input device into kana-kanji characters and outputs it!
! The present invention relates to a single kanji conversion device that converts an input character string into a single kanji, which is used in a Japanese front end (such as a word processor) or a Japanese front end that converts the input plain name character string into kana-kanji and sends it to a processing device.

``Prior art'' When inputting a proper noun such as a family name or place name in a kana-kanji conversion device, the noun is often not registered in the word dictionary. For example, 0, which requires kanji conversion and input,
If you want to enter rTsuneakiko, ``TsuneakiJ
Even if you convert ``Kana-Kanji'' into kana-kanji, the desired conversion result is often not obtained, and it is necessary to convert ``Ko J'' and ``Sho'' one character at a time.

Since the number of proper nouns is enormous and it is impossible to register them all in a dictionary, conversion of single kanji like this always occurs. In conventional kana-kanji conversion devices, the following are mainly provided as means for inputting single kanji.

Two-stroke method: enter the code (JIS code or period code) of the kanji you want to input and convert it: Decide on a special code for each vague character and input it. "If,
``Problem to be Solved by the Invention'' Entering and converting ``Let's'') The above code input is a time-consuming method as it is necessary to look up the code of the kanji you want to input in a code book or the like.

The two-stroke method described above requires memorizing special codes and requires a trajectory. The reading input above is -4
has many homonyms (for ``sho'', there are chapters, 冨, 小, 竿, etc.), and it is necessary to press the next candidate key many times to get the desired kanji. Yes, it wasn't very easy to use. In other words, a simple means for converting single kanji has not been provided in the past.

``Means for Solving the Problems J'' According to this invention, a shape dictionary that describes the shapes of kanji,
A radical dictionary that describes how to read radicals, a kanji dictionary that describes how to read and shape kanji, a kana-kanji converter that treats a given string as a clause and converts it from kana to kanji, and a kana-kanji transformation part. It is equipped with a kana-kanji conversion dictionary used by Call either the process, phrase specification process, or word specification process and pass the input string.

1. Designation based on the kanji or radical names that compose the kanji and their positional relationship. 2. Designation based on the reading of the compound word that contains the kanji and the reading of the kanji in the compound word. 3. A predicate ending that includes the kun reading of the kanji. Designation by shape 4 When the Kanji in question is a single character that becomes a word, it is designated by the pronunciation of the word.The shape designation processing unit is called when the specified format is 1, and calculates the Kanji or radical name that is part of the given character string. Extracts information about the substring that is the string being expressed and the positional relationship such as bottom, right, etc.

Whether these partial character strings are radical names is checked using a radical dictionary.0 For character strings that are not radical names, they are processed as input to this single kanji conversion device to obtain a set of kanji candidates. Using the radical names or kanji candidates obtained by these methods and the above relationship information, the shape dictionary and the kanji information dictionary are searched to obtain kanji candidates for the input character string and output.

The idiom specification processing unit is called when the specified format is 2, and from the given character string, it extracts the character string that is the pronunciation of the idiom and the positional information that indicates which part of the idiom's pronunciation corresponds to the pronunciation of the kanji. Extract.

Next, using a kana-kanji conversion unit, the pronunciation of the compound word is converted into kana-kanji characters to obtain a kanji compound word string. From this and the previous position information, obtain kanji candidates for the input character string, search the kanji information dictionary and select those that have the character string specified as the reading of the kanji from among these kanji candidates, Use as kanji candidates for the input string.

The word specification processing unit is called when the specified format is 3.4, converts the given character string to kana-kanji using the kana-kanji conversion unit, and converts the given character string to kana-kanji and converts it into a single kanji character representing the word or a pragmatic clause containing one kanji character. get.

Among the single kanji characters contained therein, the kanji information dictionary is searched to select a kanji that has the input character string as a reading, and outputs it as a kanji candidate for the input seven character string.

With this structure, you can specify the single kanji you want to input as one of the following four types.

1 Example of specifying the kanji you want to convert by specifying the kanji by the kanji or radical name that composes the kanji and their positional relationship. , an example of specifying the kanji by the reading of the compound word containing the kanji and the pronunciation of the kanji in the idiom. It is specified by the disjunctive final form.

Example: Ōkii → Add a large number → Add 4. Specification by word When the kanji in question is a word with one character, the kanji you want to convert is specified by the reading of that word. Compared to the conventional method, this method does not require much skill and does not require a codebook or the like. Furthermore, when designated in these formats, the number of candidate kanji characters is much smaller than when designated simply by reading, so the effort of selecting candidates, such as pressing the next candidate key, can be reduced. In particular, these formats are similar to the explanations that humans use to explain kanji using words, and users can input the necessary kanji simply by inputting the same explanations that they normally use. This leads to a reduction in the intellectual load.

Embodiment FIG. 1 shows the configuration of an embodiment of the present invention. Part 5, radical dictionary 6, shape dictionary 7, kanji information dictionary 8, kana-kanji conversion dictionary 9
It becomes more. The kana-kanji conversion unit 5 and the kana-kanji conversion dictionary 9 are general kana-kanji conversion devices used in word processors, etc.
It has the function of converting a given string of characters into kana to kanji, treating it as a phrase, and returning the conversion result. In this invention, the internal structure of the kana-kanji conversion section 5 and the kana-kanji conversion dictionary 9 is not specified.

The input string has one of the following formats.

Format 1 String 1 + ((1 delimiter) + (bottom 1 right 1
Middle 1 space)) + (1 delimiter) cross string 2 0 can be omitted, ()) indicates selection.

Here, character string 1 and character string 2 are radical names or inputs for this single kanji conversion shown below, and this input is character string 1
, character string 2 specifies a radical name or kanji, and specifies a kanji composed of these parts combined in a positional relationship such as bottom, right, etc.

Format 2 Character string 1 + (1 delimiter) part of the cross string l Here, character string 1 is the pronunciation of the idiom, and this input is the character string 1 among the kanji that make up the idiom specified by character string -1. Specifies the kanji with the reading in column 1.

Format 3 Character strings other than 1 and 2 above are the pronunciation of a final phrase - a phrase, or the reading of a word consisting of a single Kanji character, and this input specifies the Kanji that appears there.

The input character string is analyzed by the input character string analysis section 1. The processing flow of the input character string analysis unit 1 is as shown in FIG. 2, and the format determination of the input character string, which determines which format the input character string is in, and calls the necessary processing, is as follows: For format 1, the input string is ((1 delimiter)
Format 2, if the input string contains (1 separator) and the following characters are This is done depending on whether it is part of the previous string. Format 1.
Character strings that do not match format 2 are determined to be format 3.

When it is determined that the input character string is in format 1, the shape designation processing section 2 is called. The flow of processing of the shape specification processing unit 2 is shown in FIG. 3. Here, first, from the input character string, the character string ((1 delimiter) + (1 delimiter at bottom 1 right 1 middle 1)) + 1 delimiter at 1 ), extract the strings before and after the string l,
Let it be character string 2. Also, as related information, bottom, right, middle,
Meanwhile, it is determined whether each character string is a radical name by searching whether any of the eight character strings 1.2 from which to extract any one is included in the radical dictionary 6.

Here, the radical dictionary 6 is a list of radical names as shown in FIG. 4. For character strings that are not 0 radical names,
Recursive processing is performed using this as input to the single kanji conversion device again. Radicals obtained by these processes,
Alternatively, the shape dictionary 7 is searched using kanji as a key.

The shape dictionary 7 has a structure as shown in FIG. 5, in which radical names or kanji are keys, and the contents include kanji that include the key as a part.

By searching this shape dictionary 7 and taking common characters from the search results, you can find a kanji that includes both the kanji or radical name expressed by string 1 and the kanji or radical name expressed by string 2. can get. The kanji information dictionary 8 is searched using these kanji as keys. The Kanji Information Dictionary 8 is a sixth dictionary in which the on reading, kun reading, single string reading, and shape of each kanji are organized into sound items, kun items, single items, and shape items.
This is a dictionary as shown in the figure. Search this kanji information dictionary 8 for the obtained kanji candidate, obtain its shape item, and check whether the related information matches the specified one! ! and outputs the matching ones as candidates.

When it is determined that the input character string is in format 2, the idiom designation processing unit 3 is called. Here, the character strings before and after (delimiter) are extracted as character string l and character string 10, respectively, and the latter character string 1 part is a partial character string that matches the first part of the former character string 1. In some cases, the position information is set to "left", when the substring matches the last part, the position information is set to "right", and when it is any other substring, the position information is set to "middle". After this, Character example 1 is converted from kana to kanji using the kana-kanji conversion unit 5 to obtain the kanji representation of the compound word whose reading is character string 1. When the 0 position information that this compound word is a compound word consisting of n characters of kanji is "left", the 0 position information that the first character of this compound word is a kanji candidate is "right j
In this case, when the 0 position information that makes the nth character of this compound word a kanji candidate is "medium", the second character to the n-1th character of this compound word are made to be kanji candidates. Among these kanji candidates, the one having the pronunciation shown in the character string 1 is selected using the sound and kun items of the kanji information dictionary 8, and is output as a kanji candidate.

When it is determined that the input character string is in format 3, the single connection designation processing unit 4 is called. Here, the input character string is converted into kana-kanji characters using the kana-kanji conversion unit 5, and the kanji characters included in the obtained result are used as kanji candidates. Among these kanji candidates, the one having the pronunciation indicated by the input character string is selected using the kun item and single item of the kanji information dictionary 8, and is output as a kanji candidate.

Next, the operation of the device will be explained in detail by taking as an example the case where the character string ``r<, the bottom of the triangle'' is input. The input character string analysis section 1 determines that this character string satisfies Format 1, and the shape specification processing section 2 is called. The shape specification processing unit 2 analyzes this input and searches the 0-radical dictionary 6 to obtain character string 1 = "kusakanmuri", character example 2 = "haukou no ho", and related information = "lower J". So, string 1 is 0 string 2, which shows that it is a radical name.
does not exist in the radical dictionary 6, so this single kanji conversion is recursively called using this as a new input.

Therefore, the character string ``haukou no ho'' is input to this single kanji converter, and it is checked whether this character string is in form 1, but it is found that this character string is not in form 1, and then it is found that this character string is not in form 1. It can be checked whether This character string is determined to be in format 2, and the phrase designation processing section 3 is called. The idiom designation processing unit 3 analyzes the character string and obtains character string 1 = 1 haukou'' and position information = ``left''. By converting the character string I from kana to kanji, the result is J in the r direction, ``hoko,''``wandering,''``housing,'' and the like. This and location information = Kanji candidates from "left" are "ho", "ho", and "彷"
You can get ``release''. Search the Kanji Information Dictionary 8 for these kanji and find ``hau'' as the reading of each kanji.
Check that it exists and print it.

As a result of the kanji conversion of character string 2, "方J""彷"
The shape specification processing unit 2, which accepts "ho", first searches the shape dictionary 7 using "kusakanmuri" as a key, and obtains the character string "...grass...yoshi...". Then, the shape dictionary 7 is searched using ``ho'' as the key, and the character string ``... 方...
- Obtain flag... j 6 Next, by extracting characters common to these two character strings, obtain the kanji candidate ``yang''. Repeat this operation for ``ho'', ``彷'', and ``hou'' to obtain all kanji candidates. In this example, the kanji candidate is "fang".
It is assumed that only that is obtained.

Finally, the obtained candidate "Yoshi" is searched in the Kanji information dictionary 8, and the related information is confirmed to be "Down" from the shape item "Grass crown - Lower one hand", and it is output as a Kanji candidate. .

As a result, as the output of the shape specification processing unit 2, a kanji candidate [hazu is obtained, and the single kanji conversion process is completed. As a result, "yoshi" is obtained.

As another example, the operation of the device when the character string "Taiyou no Yo" is input will be described. When the character string "Taiyou no Yo" is input, it is first checked to see if this character string is in format l, but it is found that this character string is not in format 1, and then it is checked to see if it is in format 2. It will be done. This character string is determined to be in format 2, and the phrase designation processing section 3 is called. The idiom specification processing unit 3 analyzes the character string and converts the 0 character string 1 into kana-kanji to obtain the character string 1 = r taiyo J, position information - "right", and as a result, ``sun J'' ``ocean J''"Compendium J is obtained. From this and the position information = "right", as a kanji candidate, "yang"
You can get "Western" and "Kaname". We searched Kanji Information Dictionary 8 for these kanji, confirmed that ``yo'' exists as a reading for each kanji, and found that these ``YoJ''``YoJ''
"Key" is output.

In the example shown here, the configuration of the shape dictionary 7 is such that the key is a radical name or a single kanji character, and the content is a character string consisting of kanji including this. It is also possible to use the name or kanji and location information as keys, and the kanji composed of these as the content.

F. Effects of the Invention As explained above, according to the present invention, it is possible to realize a single kanji conversion function that is simpler and more user-friendly than before. In other words, specifying a single kanji requires less skill than the conventional method, and also does not require a codebook or the like. In addition, when specified in these formats, the number of candidate kanji is much smaller than when specified simply by reading, so the effort required to select candidates, such as pressing the next candidate key, can be reduced. In particular, these formats are similar to the explanations that humans use to explain kanji using words, and users can input the required kanji simply by inputting the same explanations they normally use. This leads to a reduction in the intellectual load.
