Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a character string conversion device, and more particularly to generation of history information.
[0002]
[Prior art]
The applicant has already stored the inputted character string and the converted character string as a history, and if the degree of matching exceeds a predetermined degree of matching, the inputted character string may not be completely matched. An application has been filed for a method for displaying candidates for saving input that displays a candidate for conversion (see Patent Document 1). For example, if “Tokushimaken and Koshishimanohamachi” are entered from the keyboard and the conversion key is pressed to convert “Okuhama-cho, Tokushima City, Tokushima Prefecture”, these combinations are stored in the history buffer. When “Tokushimake” is entered, “Okuhama-cho, Tokushima City, Tokushima Prefecture” is displayed on the screen as a candidate for input conversion.
[0003]
[Patent Document 1]
JP-A-12-123006 (FIG. 16)
[0004]
Currently, a 7-digit display of a postal code has been introduced, and a kana-kanji conversion method is known in which a corresponding address is displayed when a postal code is input and a conversion key is pressed. Specifically, when “770-8051” is input and the conversion key is pressed, “Okuhama-cho, Tokushima City, Tokushima Prefecture” is displayed as a conversion candidate.
[0005]
[Problems to be solved by the invention]
By combining the above two inventions, even if you do not enter all of “770-8051”, when you enter “770-”, “Okuhama-cho, Tokushima City, Tokushima Prefecture” is displayed as a candidate for input conversion on the screen. Can be displayed.
[0006]
However, the above combination has the following problems. Since the correspondence between “770-8051” and “Okihama-cho, Tokushima City, Tokushima Prefecture” is only stored in the history buffer, when the operator inputs the corresponding address using only the postal code, the reading is halfway Even if the input is made, “Okihama Town, Tokushima City, Tokushima Prefecture” as a candidate for input saving conversion is not displayed.
[0007]
Such a problem is not only kana-kanji conversion processing but also a character string that determines that one record is composed of a plurality of columns and data stored in other columns is output as a candidate when one of the columns is specified. In the input process, there is a problem as well.
[0008]
SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus or method that can solve the above problems and can easily input a character string.
[0009]
[Means for Solving the Problems]
1) A character string conversion device according to the present invention includes 1) an input character string storage means for storing an input character string as a read character string, and 2) a conversion for storing a read character string and a converted character string corresponding to the read character string. Dictionary storage means, 3) storing the input character string stored in the input character string storage means in the undetermined character string storage means , and given a conversion command, the character string stored in the input character string storage means Is converted into a post-conversion character string with reference to the conversion dictionary storage means, and stored in the undetermined character string storage means. 4) When a confirmation command is given, it is stored in the undetermined character string storage means. A confirmation means for storing, as history information, a combination data of the written character string and a corresponding reading character string stored in the input character string storage means, and 5) the input character string storage Reading characters stored in the means When there is a reading character string that exceeds a predetermined degree of matching in the history information for a column, the character string conversion device includes notification means for notifying a corresponding converted character string as a saving input candidate, 6) A keyword is associated with the converted character string stored in the conversion dictionary storage means. 7) When the conversion instruction is given to the conversion means, the keyword exists in the input character string. And if it exists, it is converted into a corresponding converted character string, and 8) the confirmation means is when the keyword is included in the written character string stored as the history information. Refers to the conversion dictionary storage means, and stores the set data associating the converted character string associated with the keyword with the reading character string as the history information.
As described above, when the keyword is included in the character string after the keyword for a certain converted character string is input and confirmed, the converted character string and the reading character string associated with the keyword are stored as history information. Thus, even when a keyword is determined without being converted into a post-conversion character string, it is possible to perform input-saving conversion for the pre-conversion character string of the keyword. Thereby, simple input becomes possible.
[0010]
2) In the character string conversion device according to the present invention, the conversion dictionary storage unit stores a postal code for an address as a keyword, and the determination unit includes the notation character string stored as the history information , When the zip code is included, the conversion dictionary storage means is referred to, and the set data in which the address associated with the zip code is associated with the reading character string is stored as the history information.

Thus, set data in which the converted character string associated with the keyword and the reading character string are associated with each other is stored as the history. Therefore, even when the operator determines the keyword without giving a post-conversion character string conversion command, it is possible to perform input-saving conversion on the pre-conversion character string of the keyword. Thereby, simple input becomes possible.
[0013]
In this specification, the “keyword” is not only a shortened word that is a partial word of the converted character string, but also a numerical code such as a zip code or a combination code of English letters as in the embodiment. This includes cases where it is represented.
[0014]
In addition, the “record” may be in any format as long as one record is composed of data of a plurality of columns. For example, in a case where each data is associated as in a relational database format. Including.
[0015]
In addition, the “converted character string conversion command” corresponds to a command for converting a zip code into a corresponding address in the embodiment.
[0016]
In addition, “when the keyword is included in the confirmed character string” means that, when the keyword is confirmed as it is without being converted into the converted character string, half-width conversion, full-width conversion, etc. are performed. As a result, the concept includes all cases included in the confirmed character string. In addition, the case where the non-conversion key is included includes the case where the non-conversion key is pressed.

DETAILED DESCRIPTION OF THE INVENTION
1. Outline and Description of Functional Blocks An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a functional block diagram of a kana-kanji conversion apparatus 1 according to the present invention. The kana-kanji conversion device 1 includes an input character string storage unit 2, a conversion dictionary storage unit 3, a conversion unit 5, an unconfirmed character string storage unit 6, a determination unit 8, a confirmed character string storage unit 11, and a notification unit 9. .
[0020]
The input character string storage unit 2 stores the input character string as a reading character string. The conversion dictionary storage unit 3 stores a reading character string and a converted character string corresponding to the reading character string. Further, the converted character string stored in the conversion dictionary storage unit 3 is associated with a keyword. When the conversion instruction is given, the conversion means 5 converts the read character string stored in the input character string storage means 2 into a converted character string with reference to the conversion dictionary storage means 3, and the unconfirmed character string storage means 6 To remember. Further, when a conversion command is given, the conversion means 5 determines whether or not the keyword exists in the input character string, and if it exists, converts it into a corresponding converted character string, and stores the unconfirmed character string. Store in the means 6. When the confirmation command is given, the confirmation means 8 associates the character string stored in the unconfirmed character string storage means 6 with the corresponding read character string stored in the input character string storage means 2, and the history information storage means 7 is stored as history information. When the reading character string stored in the input character string storage unit 2 has a reading character string exceeding a predetermined matching degree in the history information, the notification unit 9 saves the corresponding converted character string. If the keyword is included in the confirmed character string, the confirming means 8 for informing as a candidate refers to the conversion dictionary storage means 3 and converts the converted character associated with the keyword. The column and the reading character string are associated with each other and stored as the history information.
[0021]
Therefore, even when the operator confirms the keyword without converting it to the corresponding converted character string, the input-saving conversion process can be performed by using the reading of the corresponding converted character string.
[0022]
2. Hardware Configuration of Kana-Kanji Conversion Device 1 FIG. 2 shows an example of a hardware configuration in which the Kana-Kanji conversion device 1 shown in FIG. 1 is configured using a CPU.
[0023]
The Kana-Kanji conversion device 1 includes a CPU 23, a memory 27, a hard disk 26, a CDD (CD-ROM drive) 25, a keyboard 28, a display 30, a mouse 31 and a bus line 29.
[0024]
The CPU 23 controls each unit via the bus line 29 according to a program stored in the hard disk 26. In the present embodiment, Windows XP (trademark) manufactured by Microsoft Corporation is employed as an operating system (not shown).
[0025]
The hard disk 26 stores a kana-kanji conversion program 26a described later. This program is read from the CD-ROM 25a storing the program via the CDD 25 and installed in the hard disk 26. In addition to the CD-ROM, a program such as a flexible disk (FD) or an IC card may be installed on a hard disk from a computer-readable recording medium. Furthermore, it may be downloaded using a communication line.
[0026]
In the present embodiment, the program stored in the CD-ROM is indirectly executed by the computer by installing the program from the CD-ROM to the hard disk 26. However, the present invention is not limited to this, and the program stored in the CD-ROM may be directly executed from the CDD 25. Note that programs that can be executed by a computer are not only those that can be directly executed by simply installing them, but also those that need to be converted to other forms once (for example, those that have been compressed) are decompressed. Etc.), and further executable in combination with other module parts.
[0027]
The hard disk 26 includes a kana-kanji conversion program 26a, a conversion dictionary 26b, and a saving input candidate determination rule storage unit 26c. The conversion dictionary 26b stores a character string conversion dictionary for converting an input character string into a converted character string. The conversion dictionary 26b further includes a postal code dictionary as shown in FIG. The zip code dictionary stores an address corresponding to the zip code and its reading.
[0028]
The kana-kanji conversion program 26a converts the input reading character string into a notation character string mixed with kana-kanji based on the character string conversion dictionary of the conversion dictionary 26b, and is stored in the reduced input candidate determination rule storage unit 26c as described later. On the basis of the rules, in the reduced input conversion mode, conversion to candidates that the operator would like is performed. In the present embodiment, the rule disclosed in Patent Document 1 is used as such a reduced input candidate determination rule, but the present invention is not limited to this.
[0029]
The memory 27 includes a confirmed character string buffer 27a, a reading buffer 27b, an extended history buffer 27c, and an undetermined character string buffer 27d. The unconfirmed character string buffer 27d stores a character string before confirmation. The confirmed character string buffer 27a stores the notated character string and the read character string after confirmation. The input reading character string is stored in the reading buffer 27b. As will be described later, the extended history buffer 27c refers to the conversion dictionary, and stores the correspondence between the notation character string not directly input and the reading character string. In addition, the memory 27 stores various calculation results and the like.
[0030]
3. Next, a kana-kanji conversion program stored in the hard disk 26 will be described with reference to FIG. In the following, after inputting the postal code “770-8051” and confirming it, the reading “Tokushimaken ...” of the address “Okihama-cho, Tokushima City, Tokushima Prefecture” associated with the postal code is in progress. An example of displaying the input-saving conversion candidates when input up to is described.
[0031]
First, the operator inputs “7” from the keyboard 28. The CPU 23 determines the type of the input key (step S1 in FIG. 4). In this case, since the key type is a character input key, the character string “7” is stored in the reading buffer 27b and the display 30 is displayed. Are displayed in an unconfirmed state (step S3). The CPU 23 determines whether or not a stored character string buffer 27a or extended history buffer 27c is stored that matches the saving input candidate determination rule (step S5). In this case, since these buffers do not match, the process returns to step S1. Similarly, the operator inputs “7” “0” “−” “8” “0” “5” “1”. As a result, “770-8051” is stored in the reading buffer 27b and the undetermined character string buffer 27d, and the character string stored in the undetermined character string buffer 27d is displayed in the undetermined state on the display 30.
[0032]
In this state, the operator presses a confirmation key (not shown). The CPU 23 determines the type of the input key (step S1), and in this case, since it is a confirmation key, the CPU 23 reads it into the confirmed character string buffer 27a as “770-8051” and expresses “770-8051”. Is stored (step S18), and the determined “770-8051” is displayed in a confirmed state on the display 30 (step S19).
[0033]
The CPU 23 determines whether or not the character string stored in the confirmed character string buffer 27a in step S18 includes a zip code as a written character string (step S21). In the present embodiment, when a three-digit number and a four-digit number are combined with a hyphen, it is determined that the postal code.
[0034]
When the character string includes a zip code, the CPU 23 searches the conversion dictionary 26b (step S23) and determines whether the character string exists in the conversion dictionary 26b (step S25). In this case, since it exists, the reading of the address corresponding to the postal code “Tokushima Kento Shishima no Hamachi” written as “Okuhama Town, Tokushima City, Tokushima Prefecture” is stored in the extended history buffer 27c from the conversion dictionary 26b. (Step S27). Specifically, “Tokushimaken: Tokushima Prefecture”, “Tokushimashi: Tokushima City”, “Okinohama” using reading divisions (6, 11, 18) and notation divisions (3, 6, 9) Reading and notation are stored in the extended history buffer 27c for each phrase such as “Cho: Okihama-cho”.
[0035]
Note that the CPU 23 does not perform the process of step S27 if the character string does not exist in the conversion dictionary 26b in step S25.
[0036]
Next, the operator sequentially inputs readings “to” “ku” “shi” “ma” “ke” “n” from the keyboard. The CPU 23 determines that the key type is a character input key (step S1), stores these character strings in the reading buffer 27b, and displays them on the display 30 in an unconfirmed state (step S3). The CPU 23 refers to the saving input candidate determination rule and determines whether or not it matches the reading character string stored as the history information (step S5). For example, as the above-described rule for determining an input candidate, a rule is stored that “if the reading coincides with the reading stored in the confirmed character string buffer 27a or the extended history buffer 27c, it is determined as a candidate for the input to the consecutive phrases”. If yes, the CPU 23 displays on the screen that “Okihama Town, Tokushima City, Tokushima Prefecture” exists as a candidate for saving input (step S7). In this embodiment, the display using the tooltip 61 as shown in FIG. 5 is performed as the display method of such a reduced input conversion candidate. However, any display method of the candidate may be used. In FIG. 5, the character string “770-8051” is displayed in a confirmed state, and “Tokushimaken” is displayed in an unconfirmed state.
[0037]
The operator presses the saving input candidate confirmation key when the saving input candidate is a character string to be input. The CPU 23 determines whether or not the saving input candidate confirmation key is pressed (step S9). When this key is pressed, conversion processing is performed on saving input candidates (step S11), and steps S18 and S19. In the same manner as described above, storage in the confirmed character string buffer and display in the confirmed state are performed (steps S12 and S13).
[0038]
If the key is a conversion key in step S1, conversion processing using the conversion dictionary is performed as in the conventional case (step S15). To confirm the conversion candidate, the confirmation key may be pressed. Thereby, the process after step S18 is performed.
[0039]
As described above, in this embodiment, when the 7-digit postal code is determined without being converted into an address, the reading and notation of the corresponding address is stored in the extended history buffer 27c using this as a keyword. did. Therefore, once the zip code is determined, even if the reading of the notation character string corresponding to the zip code is not input, the input-saving conversion by the reading can be performed.
[0040]
Further, the data stored in the extended history buffer 27c is stored by dividing into phrases using the reading delimiter and notation delimiter information stored in advance in the dictionary. Therefore, it is possible to perform input-saving conversion from a part of the address (for example, “Tokushimashi”).
[0041]
4). Other Embodiments In the present embodiment, the case where the postal code is used as a keyword has been described. However, in the case where a word different from the reading of the converted character string is converted as a keyword, the present invention can be similarly applied. . For example, an abbreviation, a formal name and its reading, a management number, a management target name and its reading, a URL, a site name corresponding to the URL and its reading, and the like may be registered in the dictionary.
[0042]
The present invention can be similarly applied to a voice input type Kana-Kanji conversion device that inputs a character string to be input by voice.
[0043]
In addition to the Kana-Kanji conversion device, one record is composed of a plurality of columns, and when any one of the columns is specified, character string input processing for determining data stored in the other columns as output candidates The same applies to.
[0044]
When storing in the extended history buffer 27c, the part of speech information may be stored together. Thereby, when there are a plurality of candidates for saving input, for example, a specific part-of-speech information is given to a word strongly associated with the unique person name, and the unique person name is given priority immediately after the word is confirmed. By executing this, the candidates can be displayed reliably. For example, the reading “Tanakatatarou”, the converted character string “Taro Tanaka” are registered in the extended history, and the part-of-speech information that indicates that the “name” is strongly associated with the unique person name is added. Enter “Botamochi” to convert and confirm “Shelves from shelf”, then enter “Shimei” to convert to “Name” and confirm. Thereby, the part-of-speech information indicating that the immediately following unique person name is prioritized is stored. After that, when saving input conversion is performed by reading “Tanaka”, “Taro Tanaka” is preferentially output over the recently confirmed “Shelf to botton”.
[0045]
In the above embodiment, the CPU 23 is used to realize the function shown in FIG. 1, and this is realized by software. However, some or all of them may be realized by hardware such as a logic circuit.
