Abstract

PURPOSE:To reduce the input burden on a user in a handwriting input type document preparing device by enabling the KANA (Japanese syllabary)-KANJI (Chinese character) conversion of an input character string containing KATAKANA (square form of Japanese syllabary) characters. CONSTITUTION:A character recognition part 13 recognizes character string information handwritten and inputted at an input part 11 and the input character string as the recognition result is stored in an input character string storage table 14. Then a character replacement part 15 detects the KATAKANA characters in the input character string and replaces the KATAKANA characters with HIRAGANA (cursive form of Japanese syllabary) and then a KANA-KANJI conversion processing part 17 performs the KANA-KANJI conversion of the character string after the replacement, detects a successive KATAKANA character string, and adds the KATAKANA character string to the conversion word candidates obtained by the conversion processing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable document preparation apparatus such as a notebook size, and more particularly to a handwriting input type document preparation apparatus and a conversion control method used in this apparatus.

[0002]

2. Description of the Related Art Conventionally, there is a portable document preparation device of a notebook size or the like, which directly inputs a character by handwriting on a display by a pen touch operation. In such a handwriting input type document creating apparatus, character recognition processing is performed on a character string input by handwriting, and kana-kanji conversion is performed based on the recognition result.

Here, in handwriting input, hiragana characters are usually input, but katakana characters may be easier to input than hiragana characters. In some cases, it is easier to input using both hiragana and katakana characters. This is because katakana characters are generally easier to write than hiragana characters. However, when katakana characters are input, it is difficult to determine whether or not the katakana characters are input instead of hiragana characters for easy writing, and it is not possible to easily perform kana-kanji conversion.

There is a method of replacing the Katakana characters with Hiragana characters by using the "Hiragana / Katakana" shift key. With this method, when you input katakana characters, you can operate the "Hiragana / Katakana" shift key.
Kana-Kanji conversion can be performed by replacing the Katakana characters with Hiragana characters. However, it is necessary to operate the "Hiragana / Katakana" shift key every time the Katakana character is input, which causes a problem of burdening the user.

[0005]

As described above, in the past, it was not possible to input katakana characters by handwriting and convert them into kana-kanji characters. In this case, "Hiragana / Katakana"
It is possible for the user to change the Katakana characters to Hiragana characters by operating the shift key, but that operation is troublesome and it takes time and effort to use Katakana characters to simplify the input. .

The present invention has been made in view of the above points, and enables Kana-Kanji conversion of an input character string including katakana characters without requiring a troublesome operation such as a "Hiragana / Katakana" shift key. Therefore, it is an object of the present invention to provide a document creation device and a conversion control method used in this device, which can reduce the input load on the user.

[0007]

A document creating apparatus of the present invention comprises an input means for handwriting input of character string information, a character recognizing means for recognizing the character string information input by the input means, and a character recognizing means. Katakana character detection means for detecting whether or not the character string information recognized by the recognition means includes katakana character information, and the katakana character information detected by the katakana character detection means is replaced with hiragana character information. And a converting means for converting the character string information after being replaced by the replacing means into converted word information, and the katakana character information is continuously input, the conversion means obtains the converted word information. A virtual candidate means for adding the katakana character information to the conversion word information as a conversion word candidate, and the katakana sentence by the virtual candidate means. Characterized by comprising an output means for outputting the converted word information that contains information.

According to the conversion control method of the present invention, character string information inputted by the handwriting input method is subjected to character recognition processing, and based on the recognition result, the character string information is converted into converted word information corresponding to the character information. In the document creation device to detect whether or not the character string information recognized by the character recognition process includes katakana character information, if the katakana character information is included, the katakana character information is detected. Replaces with Hiragana character information, converts the replaced character string information into conversion word information, and converts the Katakana character information to the conversion word information when the Katakana character information is continuously input. The feature is that it is added as a word candidate.

[0009]

According to the above configuration, when the character string information includes katakana character information, the katakana character information is replaced with the hiragana character information, and the converted character string information is converted. If there is a continuous Katakana character string, the Katakana character string is added to the conversion word candidates obtained by the conversion process. Therefore, when the katakana character information is input, it can be easily converted without instructing whether the katakana character information is input instead of the hiragana character information.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a handwriting input type document creating apparatus. In FIG. 1, the input unit 11
Is for inputting handwritten characters and has a stylus pen 11a as shown in FIG. Display 12
In addition to displaying the handwritten character input by the input unit 11, displays various information such as the character recognition result of the handwritten character and the kana-kanji conversion result. Here, in the embodiment,
The input unit 11 and the display unit 12 are integrated, and a method of directly inputting on the screen with the touch pen 11a as shown in FIG. 3 is adopted.

The character recognition unit 13 performs character recognition processing on the character string input by the input unit 11. The input character string storage table 14 is a memory that stores a character string (recognition result) that is character-recognized by the character recognition unit 13. In the same embodiment, the input character string storage table 14 is stored in FIG.
As shown in (1), katakana identification information indicating the input of katakana characters is stored together with the character string that has been recognized. The character replacement unit 15 detects whether or not the character string stored in the input character string storage table 14 has Katakana characters, and replaces the Katakana characters with Hiragana characters.

The kana-kanji conversion processing unit 17 refers to the kana-kanji conversion dictionary 18 to convert the character string (character string after replacement of katakana characters / hiragana characters) stored in the input character string storage table 14 into kana-kanji characters. Kana-Kanji conversion dictionary 18
In advance, a character string before conversion and a character string of a conversion word corresponding to the character string are stored in advance. Further, in this embodiment, the kana-kanji conversion processing unit 17 refers to the katakana identification information stored in the input character string storage table 14,
If there are continuous Katakana character strings, it is assumed that the Katakana character strings were in the Kana-Kana conversion dictionary 18,
Performs processing to be added to conversion word candidates. The conversion result storage table 19 is a memory for storing conversion words (including virtually added Katakana characters) converted by the Kana-Kanji conversion processing unit 17.

FIG. 2 is a diagram showing the configuration of the input character string storage table 14. The input character string storage table 14 stores the character string recognized by the character recognition unit 13 together with the katakana identification information. Here, the character string "Aishu" and "A" and "A" in the character string are stored. A flag "1" as katakana identification information is added to "a".

FIG. 3 is a diagram showing the structure of the display screen of the embodiment. In FIG. 3, 21 is an input area and 22 is a display area. The input area 21 is provided with character input units 23a to 23d for inputting handwritten characters, a conversion instruction unit 24 for instructing Kana-Kanji conversion, and a non-conversion instruction unit 25 for instructing no conversion.

When the handwriting character is input to the character input sections 23a to 23d using the stylus pen 11a on the display screen having such a configuration and the conversion instruction section 24 is pressed, the kana-kanji converted character is displayed in the display area 22. To be done. If the non-conversion instruction section 25 is pressed, the input characters are displayed as they are. That is, it is displayed without conversion. Next, the operation of the embodiment will be described. Here, as shown in FIG. 3, an operation will be described in the case where a character string of a part of katakana characters is input using the stylus pen 11a to instruct kana-kanji conversion.

When a kana-kanji conversion is instructed after inputting a handwritten character string, the input character string is subjected to character recognition processing by the character recognition unit 13 for each character as shown in the flowchart of FIG. 4 (step S1). The recognized input character string (recognition result) is stored in the input character string storage table 14 (step S2). In this case, Katakana characters can also be recognized. Therefore, if the input character string includes katakana characters, the katakana characters are stored in the character string storage table 14 as they are. At that time, katakana identification information indicating that the character is katakana is added to the katakana character.

Here, the character replacement unit 15 takes out the characters one by one from the input character string storage table 14, detects whether or not the character is a katakana character, and if there is a katakana character, replaces it with a hiragana character. Then, it is stored again in the input character string storage table 14 (steps S3 to S6). As a result, the input character string storage table 14 finally stores a character string of only hiragana characters.

The kana-kanji conversion dictionary 17 uses the character string (the character string after replacement of katakana characters / hiragana characters) re-stored in the input character string storage table 14 in this way as an input character string, and the kana-kanji conversion dictionary. Kana-Kanji conversion is performed with reference to step 18 (step S7). In this case, for example, when the character string “Aishuru” is input by handwriting, the “Ai” in the character string is replaced with “Ai”. As a conversion word candidate, for example, "love, indigo, phase, meet, meet ..." is obtained (step S8).

Further, the kana-kanji conversion processing unit 17 refers to the katakana identification information stored in the input character string storage table 14 to check whether there is a continuous katakana character string (step S9). As a result, if there are continuous katakana character strings, the kana-kanji conversion processing unit 17 determines that the katakana character string was in the kana-kanji conversion dictionary 18, and adds the katakana character string to the conversion word candidates (step S10). . That is, in the case of the above "aisuru", the katakana character "ais" corresponds to this, and this "ais" is the conversion word candidate of the above "love, indigo, phase, meet, meet ...". Added inside. If the Katakana characters are not continuous, that is, if you input something like "Yes" or "Yes",
Since only one katakana character cannot be regarded as a conversion word candidate, it is excluded.

When the conversion word candidates are obtained in this way,
The kana-kanji conversion processing unit 17 performs grammatical processing such as inflectional ending and adjunct processing on the candidate sequence (step S1).
1), the combination is stored in the conversion result storage table 19 as a conversion result (conversion word information) (step S1).
2). The display unit 12 reads the conversion word information stored in the conversion result storage table 19 and displays it (step S11).

As described above, the katakana character is replaced with the hiragana character, the input character string after the replacement is subjected to kana-kanji conversion, and further, if there is a continuous katakana character string, it is included in the conversion word candidates. The relevant Katakana character string is added. Therefore, when you type in katakana characters by handwriting,
It is possible to perform Kana-Kanji conversion of an input character string including the Katakana character without using the “Hiragana / Katakana” shift key or the like to instruct whether the character is input as a substitute for the Hiragana character or as a Katakana character. As a result, when a character string is input, it is possible to use katakana characters that are easier to write than hiragana characters, and it is possible to reduce the input load on the user.

In the above embodiment, in order to simplify the explanation, it is assumed that no katakana character is registered in the kana-kanji conversion dictionary 18, and katakana characters are included in the conversion word candidates during kana-kanji conversion. Although not included, in practice, katakana characters and hiragana characters are also registered in the dictionary as conversion words in advance and may be included in conversion word candidates.

That is, for example, "Stalin's fault"
If you type by handwriting, first, it will be replaced as "Star-Rin no Seiji", and by Kana-Kanji conversion, you will find katakana characters such as "Star, Star-print, Rin, politics, maintenance, stomach ...". Converted word candidates including hiragana characters can be obtained. This is because the katakana character "star" and the hiragana character "star" are registered in the dictionary in advance as conversion words corresponding to the reading "star". in this case,
In the present invention, "Stalin" is added as a continuous katakana character string to the conversion word candidates of "Star, Star, Printing, Rin, Politics, Maintenance, Stomach ...", and finally "Stalin's politics, The result of the conversion is Stalin's politics ... ". Further, the method of outputting the conversion result is not limited to the display, and it is possible to easily realize, for example, outputting by voice.

[0025]

As described above, according to the present invention, katakana characters are replaced with hiragana characters, the input character string after the replacement is subjected to kana-kanji conversion, and if there is a continuous katakana character string, the conversion word is converted. Since the katakana character string is added to the candidates, the kana-kanji conversion of the input character string including the katakana character can be performed without operating the "Hiragana / Katakana" shift key. As a result, the user can input using katakana characters, and thus the burden of handwriting input can be reduced.
