Description

[Detailed Description of the Invention] This invention provides a method for converting kanji (2-byte type) into kana characters when inputting Japanese sentences written in kanji and kana mixed sentences into an information processing device such as a computer using a kana keyboard. (1 byte type)
This paper concerns a human-powered method for identifying kanji using kana characters.

Traditionally, methods for inputting Japanese sentences into information processing devices such as computers include direct input (on tablets, etc.), kana-kanji conversion, and OCR (Optical Character Recognition).
ader), but all of them convert kanji into 2-byte codes and input them, so the information processing device converts kanji (2-byte codes) and kana (1-byte codes).
It is necessary to identify the information in this section, and there is a drawback in that it cannot be shared by arithmetic machines operating on conventional single-byte code operating systems.

Furthermore, if the data is converted into a 2-byte code, processing such as sorting becomes difficult, and processing diversity is also poor. This invention was made to eliminate the above-mentioned drawbacks, and by automatically adding subdivided additional information representing the characteristics of kanji within an information processing device, Japanese sentences can be expressed uniquely using kana. It was designed to do so.

The present invention will be explained in detail below with reference to the drawings. First, in explaining the present invention, the "feature extraction type kanji input method" proposed by the present inventors will be explained.

This is a method of inputting Japanese sentences in kana phrases using a kanaken board, and converting them into sentences containing kanji and kana by enclosing patterns representing the characteristics of the characters. Figure 1 shows a keyboard input device used for input; a kana keyboard A with keys for characters, symbols, etc., and a pattern keyboard B with pattern keys representing the characteristics of the form of kanji.
It consists of

As an example, consider inputting the following sentence.

``Do a science experiment.'' The operation for inputting this example sentence using the illustrated keyboard input device is as follows.

Takagaku yen/no. Due to the characteristics of the shape of Enjitsukenwospire kanji, phrases are surrounded by vertical (example: ゜匡回), horizontal (example: ÷), and other (example: 圃) keys.
Convert to Kanji code.

However, the combination of pattern keys is not limited to this, and subdivision is also possible. This invention is based on the above-mentioned feature extraction type kanji input method.

This invention will be explained below. When it cannot be unambiguously determined even by the above-mentioned feature extraction type kanji input method, for example, for -Kagaku yen, Kawa... Yumiyo, Tahio Okazuki, J Shugen "
If there is a problem such as n, etc., and it cannot be determined (3 of pattern board B above)
(The key is uniquely determined with a conversion rate of 91%), and the operator specifies and identifies one of the three.

In this case, if the pattern keys are subdivided, the number of homophone selection operations will be reduced, but the operability will deteriorate and the input speed will decrease. Therefore, the number of pattern keys is set to an appropriate number in relation to operability, and the pattern keys are subdivided within the word dictionary file or kanji dictionary file.

When the operator selects an input action homophone, that is, when the kanji is specified from the outside, subdivided additional information corresponding to subdivided pattern keys in the word dictionary file or kanji dictionary file is generated. If it is automatically added to the input sentence, the kanji can also be uniquely defined as a kana expression. FIG. 2 is a block diagram showing an embodiment of the present invention based on the above principle, in which 1 is an input/output device, 2 is an information processing device, 11 is a kana keyboard input device equipped with a pattern keyboard, and 12 is a kanji printer. . The information processing device 2 is transmitted from the input/output device 1 to the information processing device 2 using a 1-byte code as kana + feature code, and each process is performed within the information processing device 2.
It is returned to the input/output device 1 as a byte code and printed on the Kanji printer 12.

Figure 3 is a diagram showing an example of subdivision of pattern keys.
3 indicates a manual key, and 32 indicates a subdivision key in the dictionary file.

Although the dictionary file does not have the subdivision key 32 directly, but is used in the form of a code, it is shown here as a subdivision key in order to make a clear comparison with FIG. Generally, the subdivision key 32 indicates subdivided additional information. Furthermore, as another example, the radical, hen, and structure of kanji may be assigned as subdivided additional information in the dictionary file.

In this case, Kagaku Nissin ^′7,′z? A monument lol? Each kanji is determined by the code.

As another example of the subdivided additional information in the dictionary file, in the case of the above input example in which homophones are numbered in order of frequency,
, is uniquely defined as kuchakagaku day (=kagaku).

As another example, by adding word accent information as subdivided additional information in a dictionary file and inputting kana + additional information (accent) to a voice response device, accurate accents can be easily generated. be able to.

Although the above explanation mainly uses kana, it goes without saying that the present invention is not limited to kana.

When expressing the meaning of both, kana was used. As explained above, the present invention is capable of automatically adding subdivided additional information within an information processing device.
Since a bytecode type kanji can be uniquely and easily expressed with a single bytecode type kana, it has the following advantages.

(1) There is no need to distinguish between 1-byte code and 2-byte code information within the information processing device, and the device can operate on a conventional operating system.

(2) Sorting processing (such as arranging input document titles, etc. in alphabetical order) becomes possible, expanding the response field. (
3) By converting the Kanaju additional information into Kanji code, it is also possible to access Kanji-based centers (centers with operating systems that handle 2-byte codes).

Claims (1)

[Scope of Claims] 1. In a method of inputting a Japanese sentence in kana characters to an information processing device with additional information representing the morphological characteristics of the kanji, when the kanji cannot be uniquely determined, the kanji can be inputted from outside. When specified, subdivided additional information representing the characteristics of the kanji is automatically added within the information processing device, thereby uniquely converting a 2-byte code type kanji into a 1-byte type kana. Features a kanji kana input method. 2. The kanji kana input method according to claim 1, wherein the subdivided additional information includes accent information.
