Description

Detailed Description of the Invention

[0001]

[Industrial application] The present invention relates to a difficult-to-read kanji search device for searching kanji whose reading is unknown (hard-to-read kanji) when inputting kanji in a word processor or the like.

[0002]

2. Description of the Related Art Conventionally, in a document creation process by a word processor or the like, when searching a kanji whose reading is unknown, that is, a difficult-to-read kanji, (1) total number of strokes, (2) radical and number of strokes other than radical Kanji search is performed from the Kanji code table according to the method. That is, conventionally, the obfuscation kanji is searched by using the stroke count method.

[0003]

However, the retrieval of obfuscated Kanji characters by the stroke number method has the following problems. (1) Most obfuscated Chinese characters have many strokes, and it takes time to accurately grasp the stroke count. In general, the correct answer rate for 10 strokes or more is particularly low.

(2) Since difficult-to-read Kanji characters are generally other than the corresponding Kanji characters, there are many old fonts and it may be difficult to accurately grasp the number of strokes. (3) Most strokes of Chinese characters are 5 to 20 strokes, and only 10 or more divisions can be made. For this reason, the number of Chinese characters existing in the same number of strokes is large, and if the number of strokes is wrong, it takes time to search.

(4) Kanji culture area (China, Korea, Japan, N
In IES etc.), the font is different in every detail,
The number of strokes is often wrong. In recent years, the rapid growth of economic power in the Kanji cultural area has led to a rapid increase in exchanges. In such an environment, mutual proper nouns (place names, personal names, etc.)
Is not translatable, so it will be expressed as it is, but
Many of these kanji are difficult to read. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an obfuscated Kanji search device capable of searching for obfuscated Kanji in a short time.

[0006]

The obfuscated Kanji search device according to the present invention is designed to display the first N strokes (N is a desired natural number) of each Kanji radical and the portion other than the radical. A storage means for storing four types of patterns, "\", "-", "|", and "/", and the beginning of each stroke of N strokes of the radical and non-radial portion of the search target kanji When the writing line of is divided into four types of "\", "-", "|", and "/", it is possible to capture the pattern of N fractions of the same radical and parts other than the radical. It is characterized in that it has means for pattern-searching the pattern of N fractions of the radical and the portion other than the radical captured by the means and the data of the storage means, and extracting the data of the Chinese character to be searched.

[0007]

In the storage means, the first writing line of each stroke of the first N stroke (N is a desired natural number) of each kanji radical and the portion other than the radical is "\", "-", "|". , And “/” are divided into four patterns and stored. Then, when searching for obfuscated Kanji, the radicals of each Kanji to be retrieved and the first writing line of each stroke of the first N strokes of the portion other than the radical are input in the above four types of patterns. Then, based on this input pattern, a kanji search is performed by referring to the storage means, and the search result is displayed as a candidate kanji on the screen.

As described above, the first writing line of each stroke of the first N stroke of each kanji radical and the portion other than the radical is divided into four patterns and stored in the storage means. By searching based on the pattern, it is possible to search for a desired Chinese character in a short time by inputting a combination of four types of patterns without knowing the reading of the Chinese character.

[0009]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a functional configuration of a difficult-to-read kanji search device part in a kanji input device such as a word processor.

In FIG. 1, reference numeral 11 denotes a search mode selection device for selecting two search modes, a total stroke number mode or a radical mode. Reference numeral 12 is a pattern input device, and the first writing line of each stroke of the first N stroke (N is a desired natural number) of the radical of each kanji to be searched and the portion other than the radical is "\", "-", " Input a pattern classified into four types of "|" and "/". In this case, in the total stroke number mode, the N stroke pattern including the radical is input. In the radical stroke mode, the radical is designated, and then the first N stroke pattern other than the radical is input. To do. The above four patterns are
"\", Which a JIS keyboard generally has,
The "-", "|", and "/" keys are used, but they may be separately provided as pattern input keys.

Reference numeral 13 is a rough stroke number input device, for example, the rough stroke number of the search character is, for example, small stroke number (10 strokes or less), medium stroke number (8 to 1)
6 strokes) and the number of strokes (14 strokes or more). When classifying the number of strokes, it is better to overlap several strokes. Since the rough stroke number input device 13 is used as an auxiliary device, it can be omitted.

Reference numeral 14 is a pattern search device, which refers to the total stroke number type dictionary 15 and the radical type type dictionary 16 to perform a kanji search by a pattern. In the total stroke number type dictionary 15, Chinese characters including radicals are classified into four types of patterns of "\", "-", "|" and "/" and stored in advance. In the radical-type dictionary 16, kanji are classified according to radicals, and the parts other than radicals are classified into four patterns of "\", "-", "|", and "/" in advance. Remembered Details of the pattern dictionary creating device for creating the total stroke number type dictionary 15 and the radical type type dictionary 16 will be described later.

A candidate kanji output device 17 selects a kanji character having a high correct answer probability from the kanji characters retrieved by the pattern retrieval device 14. The candidate kanji selected by the candidate kanji output device 17 is sent to the extraction result judgment input device 18 and displayed on the screen. The operator inputs the success or failure of the candidate kanji displayed on this screen. Based on this input, the determination unit 19 determines whether the candidate Chinese character is correct or incorrect. If the candidate Chinese character is incorrect, the pattern re-input device 20 is used to re-input the pattern, or the pattern additional input device 21 is used. The pattern search device 14
Send to. The pattern search device 14 executes the pattern search again based on the pattern. Then, when the correct candidate kanji is extracted, the kanji search ends.

FIG. 2 is a block diagram showing a schematic configuration of a pattern dictionary creating apparatus 30 for creating the total stroke number type dictionary 15 and the radical type type dictionary 16. Pattern dictionary creation device 3
Reference numeral 0 includes a kanji direction encoding device 31, a total stroke number type pattern extraction device 32, a radical type pattern extraction device 33, and a pattern classification device 34. The kanji character direction encoding device 31 writes (1) “\”, (2) for each target kanji according to the stroke order of the writing method (corresponding to one stroke).
There are four types of patterns, "-", (3) "|", and (4) "/". That is, the above-mentioned four types of each target kanji for each stroke according to the stroke order, that is, (1) "lower right diagonal line", (2)
The pattern is formed into "horizontal line", (3) "vertical line", and (4) "lower left diagonal line".

For example, in the case of the Chinese character "width", the "width" of the radical is "vertical", "horizontal", "vertical" in the stroke order, that is,
The patterns are "|", "-", and "|". In addition, for parts other than the radical, in the same way, in accordance with the stroke order, "-",
The patterns are "|", "-", "-", "|", .... Similarly, other kanji are coded using four types of patterns.

Then, the total stroke number type pattern extraction device 32 extracts the first N stroke patterns including the radical, for example, 5 stroke patterns of the kanji coded by the kanji direction coding device 31. For example, in the case of the Chinese character "width", the combination of patterns is "|", "-", "|", "-", "|".

Further, the radical-based pattern extraction device 33 extracts the first N strokes, for example, the strokes of 5 strokes, other than the radical, of the kanji coded by the kanji direction coding device 31. . For example, in the case of the Chinese character "width", the combination of patterns is "-", "|", "-", "-", "|".

Then, the pattern classifying device 34 classifies the patterns extracted by the total stroke number type pattern extracting device 32 to create the total stroke number type dictionary 15, and extracts them by the radical type pattern extracting device 33. The patterns are classified by radicals and the radical-type dictionary 16 is created.

The obfuscated Kanji search device shown in FIG. 1 performs the obfuscated Kanji search process using the total stroke number type dictionary 15 and radical type type dictionary 16 created as described above. Hereinafter, the search operation of the obfuscated Chinese character search device will be described with reference to the flowchart shown in FIG.

First, the obfuscated Kanji search mode is designated using the function of the search mode selection device 11 on the document creation screen (step A1). Search mode selection device 11
When the obfuscated Kanji search mode is designated, displays a screen for selecting "total stroke number mode" or "radius-specific mode" (step A2). If the "total stroke number mode" is specified here, the pattern input device 12 displays a pattern input screen for obfuscated Chinese characters (step A3). On this display screen, the pattern based on the total number of strokes of the obfuscated Kanji you want to search for is displayed as "\", "-", "|",
For example, input up to the first five strokes with the "/" key. For example, in the case of the Chinese characters "width", "矣" and "徽", "width": "|", "-", "|", "-", "|""矣":"/"," \ "," / ","-","-"" Hu ": Enter as" / "," / "," | "," | "," | ".

After the pattern is input as described above, the approximate number of strokes of the search Chinese character is input using the function of the approximate stroke number input device 13. For example, the number of small strokes (10 or less), the number of medium strokes (8 to 16), and the number of large strokes (14 or more) are input.

When the "total stroke number mode" is designated as described above, the pattern retrieval device 14 retrieves obfuscated Kanji characters within the designated stroke number using the total stroke number dictionary 15 (step A5). In this case, the obfuscated Kanji can be searched even if the number of strokes is not specified, but it is more efficient to specify the number of strokes.

The pattern search device 14 searches the total stroke number type dictionary 15 based on the input pattern, and outputs the search result to the candidate kanji character output device 17. The candidate kanji output device 17 is
The kanji having the highest correct answer probability is selected from the searched kanji and displayed at a predetermined position on the screen (step A6).
If the displayed candidate Kanji is the desired Kanji, the search process is terminated by performing a confirmation operation or the like, but if it is not the desired Kanji, the next candidate Kanji is selected by operating the next candidate key. Display it. If the desired kanji cannot be obtained as the candidate kanji, the pattern may be erroneously input, or the desired kanji may not be extracted due to the small number of input patterns. In this case, the function of the pattern re-input device 20 is used to re-input a new pattern, or the function of the pattern additional input device 21 is used to additionally input the patterns of the sixth and subsequent images. And
The search process is executed again by the pattern search device 14. When the desired kanji is obtained by re-execution of this pattern search, the search process ends.

When the "radius-specific mode" is designated in step A2, the search mode selection device 11 displays a radical input screen and inputs the radical of the search kanji (step A7). For example, in the case of the Kanji characters "width", "矣", and "徽", enter the radicals "width" → "width""矣" → "mu""徽" → "彳". When the radical is input, the pattern input device 12 displays a pattern input screen for obfuscated Chinese characters (step A8). In this display screen, the pattern of the part of the obfuscated kanji you want to search other than the radical is "\",
In the same manner as in step A, input up to the first five strokes using the "-", "|", and "/" keys. For example,
In the case of the Chinese characters "width", "矣" and "徽", "width": "-", "|", "-", "-", "|""矣":"/","-" , "-", "/", "\""徽": Input as "|", "|", "|", "/", "/". It should be noted that in the case of this "radial mode", it is not necessary to input the total number of strokes.

When the "radial mode" is designated as described above, the pattern retrieval device 14 retrieves the radical type dictionary 16 based on the input pattern and outputs the retrieval result to the candidate kanji output device. It is output to 17 (step A9). The candidate kanji output device 17 selects a kanji having the highest correct answer probability from the searched kanji and displays it at a predetermined position on the screen (step A10). If the displayed candidate Kanji is the desired Kanji, the search process is terminated by performing a confirmation operation or the like, but if it is not the desired Kanji, the next candidate Kanji is selected by operating the next candidate key. Display it. If the desired kanji cannot be extracted, the pattern is re-input as in the case of the "total stroke number mode", or the patterns of the sixth and subsequent strokes are additionally input and the search process is re-executed.

By inputting N types of four types of patterns in the stroke order as described above, it is possible to search for obfuscated Kanji in a short time. Generally, even if you don't know how to read kanji, few people make a mistake in the basic writing order. Even if you make a mistake, there are only a few cases, and you can easily get the correct answer.

As shown in the above embodiment, when four types of patterns are input up to five strokes of obfuscated Kanji, the combination is 4 to the fifth power, that is, "4 ⁵ = 1024", which is considerably subdivided. It is possible to search by computerized. Also, for example, in the Kousui dictionary, the number of characters is about 50,000, and even if characters with different fonts (simplified characters and frequent characters) are added, it is about 100,000 characters. Even if all the characters are put into a database, the amount of data will not be so large. .

In the above embodiment, when the obfuscated Kanji is searched, only the extracted Kanji is displayed. , When reading, the reading may be displayed together with the corresponding kanji.

Further, the present invention is not limited to a word processor, but can be carried out in the same manner as in the above embodiment in a computer having a kanji processing function, for example.

[0030]

As described above in detail, according to the present invention, the first writing line of each stroke of the kanji radical and the portion other than the radical of the kanji is divided into four types into a dictionary. Since the dictionary is searched based on the stored and input N stroke pattern, a desired kanji can be searched in a short time without knowing the kanji reading.
