Description

  The present invention relates to a document creation apparatus and a kana-kanji character conversion method for converting a key-input character string into a kana-kanji character.

  A kana-kanji conversion technique for converting a kana character or a character string input in romaji into a kana-kanji mixed sentence is widely implemented in so-called word processors and personal computers (PCs). For example, a method for converting an input character string into kanji or a method for converting kanji characters corresponding to kana character input with reference to a word dictionary, as described in Patent Document 1, There are various conventional techniques.

However, in the case of a character string that has been mis-keyed due to a typo, it may not be converted to kanji or may be converted to an unexpected kanji / jukugo, so that the operator himself notices the typing error and corrects the key input again. It will be redone. In this case, even if you make a mistake in typing one Roman alphabet, you can either re-enter all the kanji readings in the correct kana string or move the cursor to correct only that one character It is necessary to fix it. In other words, if you make an input mistake, you have to make many keystrokes for conversion before displaying the desired character. Further, there has been no technique for converting the target kanji into a kana character string that has been input by mistake due to such a typo.

  It is an object of the present invention to convert a character string that has been input by mistake due to an input error into a target Chinese character.

  In the present invention, in the case of a specific job, the kanji and idioms to be used can be limited to a certain range, and since it is possible to deal with in association with frequent miss inputs, a typo correction mechanism is provided. Thus, the main feature is to display the target kanji conversion candidates without having to re-key correctly.

  According to the kana-kanji conversion technology of the present invention, even if an input mistake is made with a keystroke, it is converted into a candidate character by referring to the error correction dictionary according to the specific task, so that the desired kanji mixed with the keystroke input is not required again. There is an advantage that it can be converted into sentences, and when promoting each business using mail, word processor, terminal emulator, etc., preparing a mistake correction dictionary for each business processing improves conversion efficiency and improves business efficiency Has the effect of

  When advancing each business, Kanji and idioms used according to the business situation are converted to the target by corresponding to the character string that was mistakenly entered from the front, back, left, and right keys that may cause a typing error. By preparing and referring to each business processing error correction dictionary in which candidate kanji or idioms are registered, they can be converted into the desired kanji-mixed sentence without having to re-key correctly, thereby increasing the conversion efficiency. Further, an unregistered character string with an input error is additionally registered in the error correction dictionary and applied to subsequent input errors.

  FIG. 1 is a schematic configuration diagram of an apparatus for Kana-Kanji conversion from Kana character input according to the present invention. In FIG. 1, 1 is an input keyboard, 2 is a control unit, 3 is a display unit, 4 is a general-purpose dictionary, and 5 is a mistake correction dictionary. The kana character string input from the keyboard 1 by the operator is converted to kana-kanji by the control unit 2 receiving the kanji conversion instruction by referring to the general-purpose dictionary 4 or the error correction dictionary 5 for individual business. The

FIG. 2 shows the concept of creating an error correction dictionary from a character string predicted to be a typo by using a keyboard layout when inputting Roman characters. That is, as an example 1, in the case of an ordering job, a character string mistakenly entered as “Gachu” is highly likely to be “Hachu”, and therefore, the kanji of “Order” is used as a conversion candidate to correct the mistake Register in the dictionary. In general, when a keyboard is typed using Romaji conversion, there is a possibility of an error input for “HATTYUU → Hachichu → Order” from the keyboard layout of FIG. 2 in the following cases.
GATTYU → (1) Gacchu → Order YATTYU → (2) Yatsuchu → Order NATTYUU → (3) Nacchu → Order JATTYU → (4) Jacchu → Order accordingly Therefore, in response to mistake inputs (1) to (4) Create a mistake correction dictionary that associates all of the character strings with “Order”.
Example 2: The same applies to “arrangement”.

In general, it is necessary to set some keyboard keys to register words such as kanji and idioms or to convert kana-kanji by referring to the kanji dictionary in word processor or PC document creation software. . For example, “conversion” key to input kana characters and instruct conversion to kanji, “no conversion” key to leave kana characters without conversion, “confirm” to confirm with characters converted to kanji etc. A key and a “word registration” key for registering a converted word such as kanji or idiom in a word dictionary are required. In order to confirm the conversion, there is a case where it is automatically determined that the next input is performed without pressing the “confirm” key.

  Further, in the present invention, for example, an “extended” key is used as a key for assigning a word such as a kanji or idiom, which is a missed character string, and assigning it to a word such as a target kanji or idiom and registering the word in an individual business error correction dictionary. + The case of pressing the “word registration” key is assigned to this, and this is referred to as the “force registration” key. In other words, if it is not registered in the general-purpose dictionary or the error correction dictionary, press this “forced registration” key while the input character string is displayed, and then input the error in this character string. Correct the character to the correct character, convert it to the desired kanji or idiom, and press the `` confirm '' key, the kana character string as it is entered will be associated with the target kanji or idiom and entered into the error correction dictionary It shall be additionally registered.

  FIG. 3 is a flowchart showing a processing flow from kana character input to kanji conversion according to the present invention. With reference to FIG. 3, the processing flow for Kanji conversion will be described with reference to the error correction dictionary created based on the concept shown in FIG. At the start of a business, by checking the business content, a mistake correction dictionary for the business is selected. In this embodiment, a case where “ordering work” is selected from the estimation work, the ordering work, and the ordering work is shown. A general-purpose dictionary 4 is prepared and referred to for kanji conversion related to all tasks. In addition to this general-purpose dictionary, error correction dictionaries are prepared for each business. In this embodiment, business error correction dictionaries 5 to 5 for “estimation business”, “order receiving business”, and “ordering business”. Can be referenced. In FIG. 1, a case where “ordering service” is selected will be described as an example.

  When a hiragana character string is input from the keyboard 1 by the operator's romaji input and the conversion key is pressed by the operator (step S1), first, a kanji conversion character such as an idiom corresponding to the input character string is read by the general dictionary 4. Are retrieved (step S2). As a result of the computer search, if there are several candidates and “Y”, these are converted and displayed sequentially (step S3), and whether or not the character converted to kanji is the target one (step S4). Thus, if it is not the target kanji, the “conversion key” is pressed (step S5), and the next candidate character is displayed.

  If the operator determines that the desired kanji is not obtained even if steps S3 to S5 are repeated, the process proceeds to step S7 by pressing the no-conversion key. In step S1, if the corresponding kanji is not searched from the beginning even when referring to the general-purpose dictionary with the conversion key, the computer proceeds to step S7 in the same manner by determining that there is no candidate. On the other hand, when the target kanji is obtained in step S4, the process proceeds to “Y”, and the operator presses the confirmation key to determine the target character from the candidate characters (step S6). “Hatchu” is converted to “Order” and finalized.

  Returning to step S7 again and continuing the description, in step S7, the computer determines that there is no kanji corresponding to the general-purpose dictionary, and the operator attempts conversion by the error correction dictionary 5 based on the recognition of the typo. Waiting for the conversion key to be pressed. In the present embodiment, reference is made to the mistake correction dictionary 5 for the business A which is an ordering business. If there is a candidate in the search result in step S8, the process proceeds to steps S9 to S11. If the target kanji conversion cannot be obtained, and if there is no candidate in the search result, the process proceeds to step S12 according to the general dictionary. This is the same as the steps S2 to S7 of the search. If the target kanji is obtained in step S10, the process proceeds to “Y”, and the operator presses the confirmation key to determine the target character from the candidate characters (step S6). As a result of referring to the correction dictionary 5, “Gachu” is converted to “Order”, and the processing ends.

  Furthermore, in step S12, since the target kanji is not registered in the general-purpose dictionary 4 or the individual business-use error correction dictionary 5, the hiragana that has not been converted and is initially input as a mistake is displayed. The character string is displayed. Therefore, the operator presses the “forced registration” key described above in order to enter a new error input character string to be additionally registered in the error correction dictionary as an error correction word / phrase. In this embodiment, since the operator has mistakenly entered “Yachchu” and there is no corresponding character string in the existing mistake correction dictionary 5, it is displayed after the operator presses the “force registration” key. When the conversion key is pressed while one character of “Yachu” in the mistaken input string is corrected to “Ha” and changed to “Hachu”, the general dictionary will be displayed. When a search is made (step S13), "Purchase" is displayed in the search result and the "Confirm key" is pressed (Step S14), the word "Yachu" is added to the mistake correction dictionary 5 in association with "Purchase". be registered. As a result, when a similar input error occurs after the next time, “ordering” is searched from the error correction dictionary 5.
