Abstract

PURPOSE:To attain highly accurate 'KANA' (Japanese syllabary)/'KANJI' (Chinese character) conversion by transmitting an input operator's intention by the strength of depressing force, i.e. an accent, applied at the time of inputting a word and reflecting the accent to 'KANA'/'KANJI' conversion. CONSTITUTION:This character processor is provided with a detecting means for detecting an accent level to be the strength of the pressing force of a key depressed in an input means and a storage means for storing the notation of word reading and the accent level and notation corresponding to the accent level detected by the detecting means is read out from the storage means based upon a conversion result from a conversion means and displayed. In the case of inputting a 'KANA' word [ha shi] e.g., the input word is converted into a 'KANJI' word [hashi] (means chopsticks in English) when the depressing force of the initial pronunciation 'ha' is strong, and when the depressing force is standard, the input word is converted into a 'KANJI' character [hashi] (means a bridge). Consequently, the input operator's intention can be reflected to conversion, a conversion rate can be inputted and the generation of misnotation can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character processing device that inputs characters while performing kana-kanji conversion and creates and edits documents such as Japanese documents.

[Prior Art] In character processing devices that input Japanese characters, it is common to input characters using kana-kanji conversion. Normally,
Even if you change the strength of the pressure applied to the key manually when inputting,
Since words can only be converted in the order stored in a dictionary that associates the pronunciation of the word with its notation, even if a kana character string with an accent in a certain part is converted to kana-kanji, the word may not be the one the person intended. There is a very high possibility that the word will be converted.

[Problem to be solved by the invention] In the above method, the intention of the inputter is completely affected by the conversion (
There is a drawback that it is not reflected. For example, if you want to put an accent on the first note, you can strongly suppress the first note.
When I input "Hashi", it is converted to "Hashi", and on the other hand, when I input "Hashi" with a weak suppression of the first sound, it is converted to "Hashi" in the same order as in the dictionary. It is not converted. If the input person's intention cannot be reflected in the conversion, not only will it be impossible to improve the conversion rate, but there is also a high possibility that the wrong font will be in the document, which is an undesirable situation.

[Means for solving the problem (and effect)] According to the present invention, the inputter's intention is reflected in the conversion means by conveying the inputter's intention by the strength of the pressing force when inputting words, that is, by the accent. can be done. For example, when inputting ``Hashi'', if you manually input the first sound ``Ha'' by increasing the pressing force, it will be converted to ``Chopsticks'', and if the pressing force is set to the standard, it will be converted to ``Hashi''. . In this way, reflecting the input person's intention in the conversion improves the conversion rate and further prevents erroneous notation.

[Example] The present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an example of the overall configuration of the present invention. In the illustrated configuration, the CPU is a microprocessor that performs calculations for character processing, logical judgments, etc.
Each component connected to the control bus CB and data bus DB is controlled via the control bus CB and data bus DB.

Address bus AB transfers address signals indicating the components to be controlled by the microprocessor CPU.

The control bus CB transfers and applies control signals for each component to be controlled by the microprocessor CPU.

The data bus DB transfers data between each component device. For example, a pressure level control signal is transferred from the keyboard KB to the microprocessor-CPU via the data bus DB.

ROM is a read-only fixed memory, and is shown in Figures 4 to 4.
In FIG. 8, a control procedure and a word dictionary by the microprocessor CPU, which will be described later, are stored.

Ku. A word dictionary stores information on pronunciations, spellings, grammatical information, and accent positions of words, and is referenced in kana-kanji conversion.

Further, the RAM is a writable random access memory with a configuration of 1 word and 16 bits, and is used for temporary storage of various data from each component. In RAM, TBU
F is a text buffer, which is an area for storing document data to be created and edited as will be described later in FIG. D
B I ND is an area that stores an index of the homophone buffer area. DBBDY is the main body of the homophone buffer area, as will be described later. KBBUF is a keyboard buffer for storing input reading strings. 0RB
UF is an accent level buffer, which is an area for storing the pressing force level signal sent from the keyboard, that is, the accent level.

The KB is a keyboard that includes a pressing force sensor, character symbol input keys such as alphabet keys, hiragana keys, and katakana keys, and various function keys for instructing various functions to this character processing device such as conversion keys. The pressed key and the level of the pressing force, that is, the accent level, are transferred to the CPU via the DB, and the pressed key code and accent level are stored in the RAM.

DISK is an external storage unit for storing document data, and stores created documents on the text buffer TBUF.
Called when needed.

CR is a cursor register. The CPU can read and write the contents of the cursor register.

A CRT controller CRTC, which will be described later, displays a cursor at a position on the display device CRT corresponding to the address stored here.

DBUF is a display buffer memory that stores data patterns to be displayed. The content of document data is displayed by developing a pattern into DBUF based on the data on text buffer TBUF.

CRTC is cursor register CR and buffer DBUF
It plays the role of displaying the contents stored in the CRT on the display device CRT.

Further, a CRT is a display device using a cathode ray tube or the like, and the display of a dot configuration pattern and a cursor on the display device CRT is controlled by a CRT controller.

Furthermore, CG is a character generator that stores patterns of characters and symbols to be displayed on the display device CRT.

The character processing device of the present invention comprising these components operates in response to various kinds of human power from the keyboard KB, and when the human power from the keyboard KB is supplied, the included signal is first sent to the microprocessor C
is sent to the PU, and the microprocessor CPU is sent to the ROM
Various control signals stored therein are read out, and various controls are performed according to these control signals.

FIG. 2 is a diagram showing an example of operation of the apparatus of the present invention.

In the figure, CRT refers to a display screen. CM is a cursor, and when the next key is pressed, a character is entered (indicates the position). TS is a text screen, and the contents of the document stored in the text buffer TBUF are displayed. .MS is a monitor line, and is an area where key data entered manually is displayed one by one.When performing kana-kanji conversion, etc., the reading string is displayed on the MS, and after conversion, the conversion result is transferred to the TS. Ru.

FIG. 2(a) is a diagram showing the display format.

First, the operator attempts to convert the word "chopstick" into kana-kanji into a text buffer by manually inputting the reading "hashi" and then manually pressing the kana-kanji conversion key "/". At that time, if you input a stronger pressure on the first sound to put an accent on it, "Hashi/" will be converted to kana-kanji, and it will become "chopsticks".
This will take you to a text screen.

FIG. 2('b) is a diagram in which the operator attempts to convert "hashi" into kana-kanji into a text buffer by manually inputting the reading "hashi" and then inputting the kana-kanji conversion key "/". None of the sounds in "hashi" have accents, so if you input each sound with the standard pressing force, "hashi/" will be converted into kana-kanji and become "hashi" in the text screen (
.

FIG. 3 shows the structure of the word dictionary according to the present invention. Words are ``yomi'' (20
character), the “notation” that is the notation of its “reading”
(20 characters), "grammatical information" (10 characters) that shows the grammatical information of the "notation", and "accent level" (20 characters) that shows the information on the accent position when pronouncing the "yomi".
It has four pieces of information (characters) on a fixed-length dictionary. The "accent level" indicates the accent position of each word, and information such as Fl and Q is given to accented sounds, and "0" is given to non-accented sounds. For example, "bridge"
has the pronunciation ``Hashi'', the notation ``Hashi'', the grammatical information ``noun'', and the ``accent level J FooJJ'' that indicates the suppression of each sound at the time of input.In addition, in the case of ``Chopsticks'', the pronunciation "Hashi", spelling "Chopsticks", grammatical information "Noun"
, which indicates the pressing force at the time of each input [accent level J Ir1O1 is included in the dictionary.

FIG. 4 is a diagram showing the configuration of the keyboard buffer KBBF. The key data entered from the keyboard is −
It will be stored in this KBBF. For example, when converting kana-kanji, the reading sequence information is kept in this K until the conversion conditions are met.
It is accumulated in the BBF, and when the conversion conditions are met, it is converted to kanji and the background is cleared. For example, the characters are JIS
Each character is stored as 2 bytes using the 0208 code. In the figure, "/" means a kana-kanji conversion key, which means that the reading sequence stored up to "/" is converted into kanji.

FIG. 5 is a diagram showing the configuration of the accent level buffer 0RBF. The pressing force level signal sent from the keyboard is stored in rOJ rlJ.

FIG. 6 is a diagram showing the overall structure of a text buffer TBUF that stores the contents of document data that is being created and edited.

FIG. 6(a) is a diagram showing the overall configuration of the TBUF.

Documents are stored as sequences of characters.

FIG. 6(b) is a diagram showing the structure of each character. One character consists of 2 bytes. The MSB (215 bits) is the homophone accent level, and the remaining part (214 to 2
°bit) is the code part. The homophone accent level indicates whether the character is a homophone or a regular character; when it is "0", it is a regular character, and when it is "1", it is a homophone. For normal characters, the character code is in the code section, JI
It is stored in the S.X.0208 code. When it is a homophone, the homophone number is stored in the code section. The homophone number serves as an index in the index section of the homophone buffer area, which will be described later, and specifies a specific homophone buffer.

FIG. 7 is a flowchart of the part that takes in key human power and performs processing.

Step 7-1 is a process of taking in data from the keyboard into the power buffer KBBUF.

Hereinafter, the process branches as follows depending on the type of key existing in KBBUF. If the KBBUF contains data for a kana-kanji conversion key, it is necessary to perform kana-kanji conversion, and the process branches to step 7-2. In step 7-4, the ``reading'' at the time of input and its respective sounds are calculated. The information on the strength of the pressing force is compared with the word dictionary, and based on that, the notation j, which is the result of the conversion in step 7-5, is displayed.

Otherwise, in step 7-3, other processes such as cursor movement, insertion, deletion, etc. that are found in general character processing devices are performed.

FIG. 8 is a detailed flowchart of "input accent judgment" in step 7-2 and "kana-kanji conversion" in step 7-4 in FIG.

In step 8-1, the "yomi" sent from the keyboard and the strength of its sound are determined and sent to the word dictionary as a signal, and in step 8-2, the signal and the "yomi" contained in the word dictionary are determined. , "notation", "grammatical information J," and "accent level" information are compared to search for "notation" that is a conversion candidate, and in step 8-3, determine which of these conversion candidates is most likely, and input. The resulting pronunciation and accent level information for each sound are set in a homophone buffer, conversion candidates are created, and the most likely word is determined as the first candidate. In step 8-4, a homophone buffer is created based on the determined first candidate.

The created homophone buffer is viewed and displayed in step 7-5.

[Other Embodiments] In the above description, the case where the dictionary has a fixed length has been described, but the dictionary can also have a variable length. The standard reading notation is ``yomi'' which is the pronunciation of a word, ``notation'' which is the notation of that ``yomi'', ``grammatical information'' which shows the grammatical information of that ``notation'', and ``yomi''. "accent level" 4, which indicates whether the pronunciation is not standard or not.
The dictionary has two pieces of information, but the length of the dictionary is made variable by inserting a code indicating the end of each data at the end of each data.

[Effects of the Invention] As is clear from the above description, according to the present invention, the intention of the person inputting the input could not be reflected in the words when converting words. By conveying the strength of the pressing force at the time of input, that is, the accent, and reflecting it in the Kana-Kanji conversion, it becomes possible to perform Kana-Kanji conversion with higher accuracy.
