Abstract

PURPOSE:To improve a conversion rate at the time of KANJI-mixed-KANA/ KANJI-converting a character string which is newly inputted to a document read from a storage device. CONSTITUTION:When an input control part 3 reads document data from the storage device 2, a KANJI mixed KANA/KANJI conversion part 6 temporarily stores the read KANJI mixed KANA character string in a converting use buffer 7 and then, executes KANJI mixed KANA/KANJI conversion. A conversion candidate control part 10 searches for the conversion candidate of the same notation with the character string inputted to the converting use buffer 7 from among conversion candidates obtained by conversion to store it in a document buffer 12 and transfers word attribute information of the conversion candidate to a word attribute buffer 13 at the same time. Thereby, as the word attribute buffer 13 can obtain word attribute information at the time of reading document data from the storage device 2, at the time of KANJI-mixed-KANA/KANJI- converting the character string which is newly inputted after this, word attribute information is referred to so as to improve the conversion efficiency.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creating apparatus for entering a kana-blended kana character string using a pen input means to create a kanji-blended sentence, and in particular, it is already stored in an external storage device or the like. The present invention relates to a process for performing kanji-mixed kana-kanji conversion when reading a document to obtain the word attribute information, and improving the kanji-mixed kana-kanji conversion efficiency at the time of proofreading / editing a document.

[0002]

2. Description of the Related Art Conventionally, when character input and accompanying conversion processing are continuously performed using a document creation apparatus, input word conversion is performed by using word attribute information such as part-of-speech information of the immediately preceding word and word breaks. It can be used with high accuracy.
Further, in a device having a function of securing information of a word selected by an operator on a memory during document creation, even when a word is inserted and converted at an arbitrary position of a document already created,
It is possible to perform accurate conversion using the word attribute information immediately before or immediately after. However, in the case where a document created by the document creation device is stored in a file or the like as described above, and then newly read to create or edit the document, a special example in which complete compatibility is maintained Except for the above, the documents stored in the above-mentioned files can be stored in JIS, Shift JIS, AS
Since it is limited to the character information by CII, when the document is read from the file, the word attribute information such as the part of speech and the word break collected when the document was previously created cannot be inherited. However, when a new word is input, the conversion rate becomes worse, which is a drawback.

[0003]

In the conventional document creating apparatus, when documents are exchanged between the same model or another model via a file, only standardized character codes such as JIS are stored in the file. Therefore, it is impossible to exchange the word attribute information separately acquired at the time of kana-kana-kana conversion with the same model or between other models via the file. Therefore, when reading a document from a file saved as character codes only with the same model or a different model and editing it again, the word attribute information such as word breaks and parts of speech of each word collected before saving the file is lost. It is being appreciated. Therefore,
For example, when converting a Chinese character by inserting a character string in a read document, there is no word attribute information immediately before or after, so the conversion result is the same as the input from the beginning of the sentence, and words are continuously input on the screen. There is a drawback that the conversion rate becomes worse as compared with the case where the conversion is performed.

Therefore, the present invention eliminates the above-mentioned drawbacks, and when editing a document read from a file, the word attribute information is acquired at the time of reading the document, and the character newly input to the read document is obtained. An object of the present invention is to provide a document creation apparatus and a document information input method that can improve the conversion rate by utilizing the word attribute information when converting a column into kanji and kanji.

[0005]

The present invention has an on-line handwritten character recognition means, and uses recognized kana-kanji mixed kana character information as input character information, which is referred to dictionary information and word attribute information to convert kanji kana-kana kanji characters. In the document creating apparatus, a document reading means for reading ready-made document information from an external storage device or a communication device, a converting means for performing kanji-mixed kanji conversion on the document information read by the document reading means, and Conversion candidates selected from the conversion candidates selected by the conversion candidate selecting means and conversion candidates having the same notation as the existing document information read by the document reading means and stored in the document buffer. And a finding means for finding the word attribute information.

[0006]

In the document creating apparatus of the present invention, the input means reads the existing document data from the external storage device or the communication device. The conversion means converts the document data read by the input means into a kanji / kana mixture. The conversion candidate selection means selects a conversion candidate having the same notation as the document data read by the input means from the conversion candidates obtained from the conversion means and stores it in the document buffer. The finding means finds the word attribute information of the conversion candidate selected by the conversion candidate selecting means. As a result, when a new document is input to the read document data, kana-kanji conversion can be performed by referring to the word attribute information found by the finding means, so that the conversion rate can be improved.

Is a word attribute buffer for storing attribute information of words obtained when converting kana and kanji, 14 is a display control unit for displaying the display data expanded in the display buffer 15 on the display device 16, and 15 is for the display device 16. A display buffer that expands the display data to be displayed, and 16 is a CRT or LCD that displays documents, figures, etc.
Etc. is a display device. The display device 16 has a structure in which the display device 16 and the input device 1 are integrally laminated.

Next, the operation of this embodiment will be described. Usually, an operator writes a kana-mixed kana character string on the input device 1 such as a handwriting tablet with a pen or the like, and an online handwritten character recognition unit (not shown) performs character recognition to generate a recognized character string and document it. As input to the device. Kanji mixed kana character input / conversion is an important input / conversion means in a document creation device having a pen input means. Kanji with a small number of strokes can be input as it is, and kanji with a large number of strokes can be input with its reading, It can convert kana-kanji into characters, and its input and conversion speeds are higher than those of a document creation device having a conventional pen input means (only kana character input / conversion means). At this time, the operator refers to various messages displayed on the display device 16 and interactively proceeds with the document creation work.
However, in some cases, a document may be read from the storage device 2 such as a floppy disk and additionally input to this document. Document data composed of character codes input from the storage device 2 is temporarily stored in the input buffer 4 through the input control unit 3 while waiting for conversion processing or the like, and then is again input from the input control unit 3 into the kanji / kanji / kanji conversion unit 6. Sent to.
The operation up to this point is the same for the character code input from the input device 1. The kana-mixed kana-kanji conversion unit 6 temporarily stores the input character string to be converted into the conversion buffer 7 until the input character string has an appropriate length for forming a word or a phrase.
At the stage when the length of the character string stored in the conversion buffer 7 is separated by the detection of the punctuation character code, that is, the length of the conversion target, the kanji-mixed kana-kanji conversion unit 6 converts the kanji-mixed kana-kanji While referring to the word dictionary 9 and the word attribute information of the word attribute pick-up unit 8, the Kanji-kana-kanji conversion processing of the conversion target character string is started.

Here, when there is a character other than a space immediately before or after the insertion position of the character to be converted, the word attribute acquisition unit 8 determines the part of speech of the word immediately before or immediately after or the interword connection relation by the word attribute buffer 13. To get from. Information input to the word attribute buffer 13 will be described later. The kanji-mixed-kana-kanji conversion unit 6 uses the word attribute information acquired by the word attribute acquisition unit 8 to determine, for example, when the conversion target character string is “ha” and the last part of speech is a noun, the noun “tooth” or The conversion process is performed by giving priority to the particle "ha" over "leaf", and conversely, when there is a blank immediately before or when the document is cut due to punctuation, the conversion process is given priority to the noun candidate. When the conversion process is completed, the kanji / kana-kana conversion unit 6 sends the conversion candidates to the conversion candidate control unit 11 together with the word attribute information such as the output priority and the part of speech. Conversion candidate control unit 1
1 temporarily stores the received conversion candidates and other information in the conversion candidate buffer 11. When the input is from the normal input device 1, the conversion candidate control unit 10 displays the conversion candidates via the display control unit 14 according to the output priority of the conversion candidates stored in the conversion candidate buffer 11.
, And prompts the operator to select a conversion candidate.

As a result, when the operator operates the input device 1 to perform the selection operation, the conversion candidate control unit 10 stores the character code of the conversion candidate selected by the operator in the document buffer 12, and the operator selects the conversion candidate. When the input of the next character is started without performing the selection operation, it is considered that the first conversion candidate is selected, and the character code of the first conversion candidate is stored in the document buffer 12. Also, the conversion candidate control unit 1
0 reads the conversion candidate word attribute information stored in the conversion candidate buffer 11 together with the storage position information of the conversion candidate in the document buffer 12, and transfers it to the word attribute buffer 13. On the other hand, when the document data is read from the storage device 2, the conversion candidate control unit 11 uses the same notation as the conversion target input character string stored in the conversion buffer 7 among the conversion candidates in the conversion candidate buffer 11 and The conversion candidate having the highest output priority among them is selected, the character code of this conversion candidate is stored in the document buffer 12, and the word attribute information such as the part of speech of the selected conversion candidate is stored in the word attribute buffer 13. . The display control unit 14 develops the character code in the document buffer 12 developed according to the format information from the format control unit 5 into the display buffer 15 in a bit map corresponding to the display screen of the display device 16. Similarly, the display control unit 14 develops a conversion candidate selection window in the display buffer 15 in the same manner as above while the conversion candidates are being selected. The display control unit 14 always displays the display data expanded in the display buffer 15 on the screen of the display device 16.

FIG. 2 is a flow chart showing the operation of reading a document from the storage device 2 into the document buffer 12 in the document creating apparatus shown in FIG. When one character of the document file is read from the storage device 2 in step 201, the character data is sent to the input control unit 3 in step 202, and the character data is converted from the input control unit 3 through the kana-kana-kanji conversion unit 6 for conversion. It is stored in the buffer 7. In step 203, the kana / kanji / kanji conversion unit 6 monitors the input character string in the conversion buffer 7 and starts conversion when the input character string has an appropriate length such as a word or a phrase.
Further, in step 204, the word attribute acquisition unit 8 acquires from the word attribute buffer 13 the word attribute information such as the part of speech of the word immediately before the character string to be converted and the interword connection information. In step 205, the kanji-mixed kana-kanji conversion unit 6 converts the character string in the conversion buffer 7 into kanji-mixed kana-kanji based on the dictionary data in the kanji-mixed kana-kanji conversion dictionary 9, and at this time, the word attribute acquisition part 8 By referring to the attribute of the immediately preceding word obtained, the candidate kanji can be connected or not and the priority is determined. In step 206, the kanji-mixed kana-kanji conversion unit 6 stores the conversion candidates obtained by the kanji-mixed kana-kanji conversion in the conversion candidate buffer 11 together with the written character string, word attributes, and priority information.

In step 207, the conversion candidate control unit 10 searches the conversion candidate buffer 11 for a conversion candidate that is the same as the data stored in the conversion buffer 7, that is, the same notation as the input character string. As a result, when the conversion candidates other than the non-conversion candidates are the same as the input notation, the conversion candidate control unit 1
If 0, the process proceeds to step 208, the candidate having the highest output priority is selected from the same conversion candidates, and the word attribute of the candidate stored in the conversion candidate buffer 11 is stored in the document buffer 12 as a character string. It is stored in the word attribute buffer 13 together with the planned position. At the same time, in step 210, the conversion candidate control unit 10 stores the notation character string (selected conversion candidate) in the document buffer 12. On the other hand, if the conversion target character string is a word that is not registered in the dictionary, or if all the connections before and after are prohibited due to the grammatical connection judgment, the conversion target character string is regarded as a non-conversion candidate as the input notation. The conversion candidate buffer 11 is loaded. At this time, if the conversion target character string matches only the non-conversion candidate, the conversion candidate control unit 10 selects this and selects the word attribute buffer 13 as well as the character string storage planned position in the document buffer and the step of analysis failure. It is stored at 209. At the same time,
The conversion candidate control unit 10 stores the notation character string in the document buffer 12 in step 210. In step 211, the display control unit 14 expands the character string stored in the document buffer 12 in the display buffer 15 according to the format set by the format control unit 5, and then displays it on the screen of the display device 16. indicate. When the screen is displayed, the kanji / kanji / kanji conversion unit 6 initializes the conversion buffer 7 in step 212 to prepare for the next conversion, and reads the next character from the storage device 2 via the input control unit 3. The processing from step 201 onward is repeated. However, step 21
When the input control unit 3 determines in 3 that the file in the storage device 2 is the end, the reading of the character string from the storage device 2 is terminated.

FIG. 3 is a flowchart showing a normal character input document creating process of the document creating apparatus shown in FIG. The character string input from the input device 1 in step 301 is input by the input control unit 3 and the Kana-Kanji conversion unit 6
Is stored in the conversion buffer 7 in step 302. In step 303, it is determined whether or not the data stored in the conversion buffer 7 is the conversion target by the conversion instruction from the operator or the recognition of the kanji-mixed kana-kanji conversion unit 6, and if it is not the conversion target, step 3
Returning to 01, if it is a conversion target, the process proceeds to step 304. At step 304, the word attribute extracting unit 8 detects the insertion position of the character string to be converted at the same time as the conversion is started from the cursor position or the like, and at step 305, the document position is detected based on the detected position and the set format. The corresponding position in the buffer 12 (see FIG. 5) is obtained, and the attribute information of the word immediately before the character string insertion position is found from the corresponding word attribute buffer 13 (see FIG. 6) in step 305, and the attribute of the word immediately after is acquired. The information is retrieved at step 306.

The kana-kanji kana-kanji conversion unit 6 performs step 3
At 07, Kana-Kanji conversion of the character string in the conversion buffer 7 is performed by referring to the Kana-Kanji conversion dictionary 9 containing Kanji and the word attribute information before and after in the word attribute acquisition unit 8 and the Kana-Kana conversion is obtained. The candidate of is stored in the conversion candidate buffer 11 in step 308 as shown in FIG. 4 together with the notation character string, the word attribute, and the output priority. Next, the conversion candidate control unit 10 performs candidate selection different from that at the time of reading from the storage device 2, but in step 309, the conversion candidate having the highest output priority as a temporary selection is selected.
Display on the screen of 6. Unless the operator gives a candidate selection instruction, it is assumed that the displayed conversion candidate is selected. However, when the operator gives a next candidate selection instruction or a batch display selection instruction, the conversion candidate control unit 10
In step 310, a selection window or the like is activated to wait for the operator to select a candidate. When the conversion candidate is selected in this manner, the conversion candidate control unit 1 is selected in step 311.
0 is the notation character string of the corresponding conversion candidate stored in the conversion candidate buffer 11 as shown in FIG.
2 and stores the document buffer 12 in step 312.
The word attribute is stored in the word attribute buffer 13 as shown in FIG. When the character string of the selected candidate is stored in the document buffer 12, the display control unit 14 displays the character string of the selected candidate in the display buffer 1.
By expanding to 5, the character string of the candidate selected in the document being displayed on the screen of the display device 16 is displayed in step 313. After that, when the selection of candidates is completed, the kana-kana kana-kanji conversion unit 6 initializes the conversion buffer 7 in step 314 in preparation for the next input.

FIG. 4 shows the conversion candidate buffer 11 shown in FIG.
It is a figure showing an example of data storage. In this example, as a conversion example, a data example in the case of inputting "Shiga begins" is shown. The notation character string Oxff is a separator indicating a break in a homophone. If the same word as the input notation does not exist in the dictionary, a non-conversion candidate having “no” in the part of speech is added as a homophone. The operator performs selection processing in units of homophones. Further, when “match begins” is input by reading from the storage device 2, the kanji / kana mixing conversion unit 6 selects “match” “ga” “start” “.” Regardless of the priority order. .

FIG. 5 is a diagram showing an example of data storage in the document buffer 12 shown in FIG. In the document buffer 12, the character codes of the document being created are stored in order, and these character codes are expanded according to the setting format at the time of printing or screen display. FIG. 6 is a diagram showing an example of data storage of the word attribute buffer 13 shown in FIG. Word attribute buffer 13
Stores the word attribute data of the selected candidate, and this word attribute data is transferred from the conversion candidate buffer 11 by the conversion candidate control unit 10. The storage position of the character code in the document buffer 12 shown in FIG. 5 is indicated by the address of the document buffer in which the corresponding character string is stored. This address is the word attribute buffer 1 shown in FIG.
3 corresponds to the storage position. As a result, the word attribute acquisition unit 8 can acquire the attribute information of the word including the designated character from the word attribute buffer 13 shown in FIG. 6 using the storage position of the document buffer 12 as a key.
In addition, the part of speech and the connection relation stored in the word attribute buffer 13 shown in FIG. 6 are referred to when the conversion candidate is connected and the priority is determined during the conversion process of the Kanji / Kana conversion unit 6.

According to the present embodiment, when reading the document data from the storage device 2, the Kana-kana kana-kanji conversion unit 6 performs all kanji-kana kana-kanji conversion processing on the read kana-kanji kana-kana conversion string, and the resulting conversion candidates are obtained. A conversion candidate that is the same as the character string of the document data input from the storage device 2 is selected from the inside and is stored in the document buffer 12. Therefore, when performing the Kanji-mixed Kanji conversion process, the word of the document data Word attribute information such as breaks and parts of speech can be secured in the word attribute buffer 13. Therefore, when performing editing work on a document read from the storage device 2, particularly when inserting a character string, etc., using the word attribute information before and after the insertion position, kana characters mixed with kanji of the inserted character string Since conversion can be performed, the conversion efficiency at this time can be improved to the same level as in the case where document data is continuously input and edited.

[0018]

As described above, according to the document creating apparatus and the document information input method of the present invention, when the document read from the file is edited, the word attribute information is acquired and read when the document is read. When a character string to be newly input to a document is converted to kanji containing kanji, the word attribute information can be used to improve the conversion rate.
