Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for inputting Chinese characters, and particularly to a method for inputting Chinese characters that is optimal for inputting sentences in Chinese consisting only of Chinese characters.

[Technical Background of the Invention] Kanji characters are characterized by their accuracy and speed of communication, but the large number of types of characters and complex fonts make them a major hurdle in computerization.

When processing data using a computer in Chinese, the biggest problem is how to input Chinese characters.

This problem is not limited to data processing by a computer, but is also a major problem when outputting a block copy using a computer typesetting machine or inputting character data for output to a display device, printer, etc.

There are approximately 9,000 types of kanji used in everyday Chinese, so if you assign one key to each kanji character on a kanji input device, you would have to prepare nearly 10,000 keys on the keyboard. This results in an increase in size, and is also impractical in terms of input speed.

Therefore, in order to solve these problems, research has been actively conducted on small keyboards and speedy input methods.

When a kanji is broken down into component parts called root parts, a kanji character can be expressed by a combination of multiple root parts.

Therefore, the idea is that if you use a method that specifies and inputs a single kanji based on a combination of these character roots, you will need far fewer keys than when you use one key per kanji. Based on this, several input methods have been announced.

Examples of methods for inputting kanji characters by combining a plurality of character roots in this manner include the square code method (the word code means a number), the triangular code method, and the like, which will be described below.

Of these, we will first give an overview of the square and triangular knitting methods below.

The square code method focuses on the fact that kanji are generally square with four corners, and first defines 10 basic character roots, and expresses them with Arabic numerals from 0 to 9. The roots of the corners are spread out in the order of upper left, upper right, lower left, and lower right corners, and are encoded as a 4-digit decimal number.

Figure 2 shows an example of the basic character roots, codes, and coding of the square code.

For example, when inputting the kanji ``bushi'', the desired kanji can be input by keying in the numbers 2, 3, 2, and 3 corresponding to the basic character roots at the upper left, upper right, lower left, and lower right of the kanji.

However, with this kanji input method, for example, both "〓" and "〓" become code "0044",
Just like when "Higashi" and "Yanagi" become "5090",
The drawback is that there are multiple different kanji characters even though they are the same 4-digit code. Furthermore, since it is necessary to touch the key four times to input one kanji, there remains a problem in terms of input speed.

The triangular code system classifies the basic codes (components) of kanji into 300 groups, further divides them into 99 groups, and gives them two-digit decimal codes from 01 to 99. Create a code table. In this case, basic codes (components) of similar shapes belong to each group, and the first digit code is made to correspond to the root of a character in the square symbol system.

The input of kanji using this triangular encoding method follows the "Z"-shaped square encoding principle, as shown in Figure 3.
Grasp the three basic brush shapes from the corners or shapes according to the order of writing from left to right, top to bottom, and outside to inside, and key in the 2 digits x 3, total 6 digits, corresponding to that shape. and enter the desired kanji. An example of the encoding is shown in FIG.

The characteristics of this triangular knitting method are that the rules are easy to remember;
This method has the advantage that the proportion of different characters in the same code is smaller than that of the square code system, and that it can be handled with a small keyboard.

However, although the proportion of different characters in the same code is small, there are still different characters in the same code, and problems still remain in computer processing.

As another kanji input method not mentioned above,
The sound/four-tone input method is also well known.

This is a method of inputting a kanji by specifying its reading using the alphabet and the four-tone symbols "-", "'", "〓", and "｀" representing the tone.

Figure 5 is a diagram showing a comparison of kanji and their readings. When inputting using the 〓on/four-tone input method, the reading is entered in alphabetical letters from the keyboard, and the four-tone input method is used to specify the kanji.

However, as can be seen from FIG. 5, this input method has the disadvantage that there are many homonyms and the desired kanji cannot always be input.

[Object of the Invention] The present invention has been achieved based on the above-mentioned points, and whereas in the conventional example described above, input is performed in units of single kanji characters, in the present invention, input is performed in units of words consisting of multiple kanji characters. The purpose of the present invention is to provide a method for inputting kanji characters, which has almost no different characters (words) of the same code, and which allows speedy input using a small keyboard. Its distinctive feature is that it assigns a code uniquely determined by the type of kanji component to each kanji component that makes up a word made up of multiple kanji characters, and a part of the above code is assembled for each kanji. In addition, in a kanji input method in which a word is inputted from a kanji input device equipped with a word search dictionary that stores a plurality of pieces of information associating words and index codes as a header code for searching the word, When inputting a word, a header code of the desired word is formed by inputting it from an input means for generating a code uniquely determined by the type of the constituent elements of the kanji, and the header code thus formed is inputted by the search means. This is to search and output words corresponding to from the dictionary.

[Contents of the Invention] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1A shows a table A of basic headings used in this embodiment. In this embodiment, when determining Table A of the basic headings, the <Issun no Width> method, which is often adopted as a character arrangement method for the dial of Japanese phototypesetting machines, is applied.

This ``Isun no Width'' method was researched and published by Toyoma Taneda at the beginning of the Showa era, and 51 basic headings are selected from about 220 headings for indexing that correspond to radicals. However, the remaining 169 subheadings are classified into similar basic headings.

This basic heading is easy to remember according to the word usage, and the name is given because the basic heading is ``Issun no Width'' at the very beginning.

<Issun no Width> is originally a rule for character arrangement, but in this example, this is applied. >Give a 2-digit decimal code according to the basic heading of the method.

Then, a part of the kanji codes that are originally attached to each kanji up to the third or fourth corner (in this example, the codes up to the second corner for each kanji) are combined to create multiple This is the entry code for words (idioms) composed of kanji.

FIG. 1B is a diagram for explaining the heading code added to a word in order to input a kanji character in units of a plurality of kanji characters according to this embodiment, and is substantially the same as the contents of Dictionary 1 described later. are the same.

First, we will explain how to assign heading codes to words.

In this example, the heading code assigned to each word is created by coding each component of each kanji that makes up the word using a basic heading of <one inch width> and combining a part of each kanji code. be done.

For example, the case where a heading code is attached to the word "bill" will be explained below.

First, we will use the above-mentioned "Z"-shaped angular coding principle to code the "law" and examine which of the 51 basic headings of ``one inch width'' each component is classified into. In the case of ``law,'' it is classified into the basic headings ``water,''``earth,'' and ``thread,'' in order, and the code at that time is ``48 51 31'' from Table A in Figure 1A.

Similarly, the code for the "draft" becomes "07 49 19".

Therefore, if you simply combine the codes attached to both kanji components, the code for "bill" becomes "48 51
31 07 49 19", but if you use this as a heading code, the number of digits will increase, and the number of input touches will also increase.

Therefore, in this embodiment, as mentioned above, the two kanji of each kanji are
Since the code up to the square minute is combined to create the heading code, the heading code is "48 51 07 49"
becomes.

In accordance with such rules, entry codes for necessary words are sequentially determined and stored in the dictionary 1 shown in FIG. 1C.

FIG. 1C shows an example of a kanji input device suitable for applying the kanji input method according to the present invention.

In the figure, 2 is a keyboard, and 2a is a group of keys for inputting a code of <1 inch width>.For example, the keys are arranged in the form of table A shown in Figure 1A, and each key top corresponds to a Basic headings are displayed. Further, it is desirable that a two-digit code corresponding to the basic heading be outputted by key input.

Reference numeral 2b is a group of keys for inputting various commands, etc., including parameters for instructing kanji-by-kanji divisions for the codes inputted from the key group 2a.

Reference numeral 3 denotes a header code temporary storage unit that stores the header code input from the keyboard 2; 4, a word corresponding to the content stored in the dictionary 1 according to the header code stored in the header code temporary storage unit 3; 5 is a word temporary storage section that stores the words searched by the word search section 4; 6 is an output section 7 for outputting the words stored in the word temporary storage section 5; and character data storage. An output control section 7 outputs output to the section 8, an output section such as a CRT display, and a character data storage section 8 for storing input character data, which is comprised of, for example, a floppy disk device, a magnetic disk device, or the like.

Next, an actual input method will be specifically explained using an example where the word "greenhouse" is input.

First, among the basic headings for the kanji character ``warm'' (one inch width), ``water'' and ``日'', which correspond to the basic headings for the first two corners, are input using the key group 2a of the keyboard 2.

Similarly, the user inputs ``冖'' and ``earth'', which correspond to the basic headings of the first two corners of the kanji character ``muro'', using the key group 2a.

With this input, the heading code "48 45 07 51" for the word "greenhouse" is stored in the heading code temporary storage section 3.

After specifying the heading code in this way,
For example, when the input code is instructed to be divided by inputting the delimiter parameter, the word search section 4 searches the dictionary 1 using the index code "48 45 07 51" stored in the index code temporary storage section 3. search for.

Through this search operation, each kanji code constituting the word "greenhouse" is obtained from the dictionary 1, and the obtained kanji code is stored in the word temporary storage section 5.

Then, by the operation of the output control section 6, the word "hothouse" corresponding to the obtained kanji code is displayed on the output section 7, and the kanji code is outputted to the character data storage section 8.

With the operations described in detail above, kanji can be reliably input word by word with fewer input operations than in the conventional case where all codes assigned to each kanji are input in sequence.

Next, other embodiments of the present invention will be described.

As a conventional example, the 〓tone/four-tone input method has already been described, but other embodiments described below are further developments of this.

Figure 6 shows the word 〓
It uses only sound. That is, the headword is constructed by omitting the four tones used to indicate each kanji character.

In this method, multiple kanji are entered word by word, so the amount of information provided for identification is larger than when entering one character at a time, and words can be identified without the need to add four tones as headwords. For this reason.

Therefore, to input a word, it is only necessary to input the headword of the desired word using the alphabet from the keyboard.

The present invention has been described above based on embodiments, but in short, the present invention extracts a part of the code or phonetic code normally required for inputting each kanji one by one for each kanji and combines them. The basic idea is to enter words in units of words.

Therefore, in the embodiments already described, the present invention is not limited to the example in which the code for up to two characters of each kanji constituting a word is used as the header code. Of course, in practice, for example, a combination of codes for one corner or up to three corners may be used as the header code.

Furthermore, in the above embodiments, the basic headings of the dictionary are determined according to the <Isun no Width> method and the 〓 sound input method, but the present invention is not limited to this, and other kanji characters can be used. It goes without saying that basic headings may be determined according to the specified method.

[Effects of the Invention] As explained above, when inputting Chinese characters consisting only of Chinese characters, conventional Chinese input methods can only input one Chinese character at a time, and other methods such as the square symbol system and triangular alphabet system, Due to the presence of different code characters, there were problems such as slow input speed, but in the present invention, input is made in units of words consisting of multiple kanji, and the heading code of the word is
A two-digit decimal code is given to the constituent elements of the kanji that make up a word according to the basic headings of the <Issun no Width> system shown in Table A in Figure 1A, and a part of the code attached to each kanji is given. (In this example, the codes up to the second corner) are combined to form the word heading code, so there are almost no different characters of the same code, so the input speed is significantly improved compared to the conventional method.
Even a small keyboard can have great effects.
