Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem of there being the need for the latest input character string to include at least one character that is the same as a corresponding one in a character string which it is desired to be converted into, because once an input character string is entirely deleted, it is impossible to register a conversion character string for the character string entirely deleted. <P>SOLUTION: This apparatus for predicting and converting character strings predicts conversion candidates for an input character string based on the input character string. The apparatus has a character string deletion detecting unit for detecting the latest input character string entirely deleted, and the function whereby a character string determined after the character string deletion detecting unit detects that the latest input character string has been entirely deleted is registered in a prediction/conversion user dictionary part as a conversion candidate for the character string entirely deleted. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a character string prediction conversion apparatus that predicts a character string to be output in response to an input.

  Conventionally, Japanese character string input has had a problem that many input operations have to be performed because kana-kanji conversion is required. Therefore, the predictive conversion function is widely known in order to realize the input of many character strings and kana-kanji conversion with fewer keystrokes as a method of performing character input or kana-kanji conversion after the user performs an input operation. ing.

The sentence creation device described in Patent Document 1 below automatically registers a character string in a predictive conversion user dictionary. This Patent Document 1 uses an input prediction provisional dictionary that stores dictionary information in which an edited character string is extracted and the character string is converted into a character string after conversion, and the input prediction provisional dictionary determined by the prediction conversion process. Is selected as a converted character string, the selected character string is used as a converted character string, and the selected character string is determined as a character string candidate. The dictionary information that reads the input character string is stored in the input prediction dictionary. Thus, the edited character string is automatically registered in the dictionary for input prediction processing.
JP 2003-256416 A

  However, in the conventional configuration, the edited character string can be automatically registered in the dictionary for input prediction processing, but if it is not confirmed that the character string converted to Kana / Kanji has been corrected, Since editing cannot be registered, editing of the character string cannot be registered if the character string to be corrected is blank. Therefore, there is a problem that when the inputted character string is completely erased, a converted character string for the completely erased character string cannot be registered.

  In order to solve the conventional problem, the character string prediction conversion device according to the present invention is a character string prediction conversion device that predicts conversion candidates for the character string based on the input character string, and is entirely erased. A character string erasure detection unit that detects the most recent input character string, and a character string that is confirmed after the character string erasure detection unit detects that the most recent input character string is completely erased. It has a function of registering as a column conversion candidate in the prediction conversion user dictionary unit, and performs character string prediction conversion.

  A character string prediction conversion device according to the present invention is a character string prediction conversion device that predicts conversion candidates for the character string based on an input character string, and detects a character string erasure detection that detects a completely erased character string. And a means for registering in the predictive conversion user dictionary unit as a conversion candidate for the all-erased character string, a character string whose input has been confirmed after detecting that the character string has been completely erased by the character string erasure detection unit With this configuration, unknown words that cannot be converted normally can be automatically registered in the predictive conversion user dictionary unit. Moreover, since the most recent input character string can be automatically registered in the predictive conversion user dictionary even if no character matches the character string to be converted, predictive conversion dictionary registration can be performed easily, and characters can be operated with fewer operations. Input can be made.

The best mode for carrying out the present invention will be described below with reference to the drawings.
(Embodiment 1)
FIG. 1 is a schematic configuration diagram of a communication terminal apparatus according to Embodiment 1 of the present invention, FIG. 2 is a flowchart for explaining the operation of a character string prediction conversion apparatus, and FIG. FIG. 4 is a diagram illustrating an example of a screen displayed on the display unit when characters are input in the first embodiment, FIG. 5 is a diagram illustrating an example of a temporary data storage unit in the second embodiment, and FIG. It is a figure which shows an example of the screen displayed on a display part at the time of a character input.

  As shown in FIG. 1, the communication terminal device includes a character string erasure detection unit 1, a text buffer unit 2, a temporary data storage unit 3, a part of speech detection unit 4, an input unit 5, a control unit 6, and a display. Unit 7, kana-kanji conversion processing unit 8, prediction conversion processing unit 9, kana-kanji conversion dictionary unit 10, prediction conversion dictionary unit 11, prediction conversion user dictionary unit 12, communication unit 13, and mail function unit 14.

  The character string erasure detection unit 1 detects that all the character strings input most recently have been erased. The text buffer unit 2 temporarily stores the input character string and the input character string that has been confirmed. The temporary data storage unit 3 includes the input character string that has been completely erased from the text buffer unit 2 and a confirmed character string that has just been detected by the character string erase detection unit 1 that all of the most recent input character string has been erased. Save. The part of speech detection unit 4 detects particles, conjunctions, and punctuation marks from the confirmed character string. The input unit 5 is a key force device that inputs characters such as kana characters. The control unit 6 stores the confirmed character string whose input is confirmed immediately after the character string erasure detection unit 1 detects that the most recently input character string has been erased. The part of speech detection unit 4 detects particles, conjunctions, and punctuation marks from the confirmed character string. The input unit 5 is an input device for inputting kana characters and the like, and includes a key such as a keyboard and a numeric keypad, and a device such as a touch panel.

  The control unit 6 extracts the most recently erased input character string detected by the character string erasure detection unit 1 from the text buffer unit 2 and stores it in the temporary data storage unit 3. When the part-of-speech detection unit 4 detects a particle, a conjunction, or a punctuation mark, the control unit 6 detects the part-of-speech of a character string whose input is confirmed immediately after it is detected that all the latest input character strings have been deleted. A fixed character string other than the particles, conjunctions, and punctuation marks detected by the unit 4 is extracted from the text buffer unit 2 and stored in the temporary data storage unit 3. The control unit 6 displays the character string input from the input unit 5 on the display unit 7.

  The display unit 7 is a screen display device and includes a liquid crystal display, a touch panel display device, an organic display, or the like. The user can interactively advance the character input process by visually recognizing the screen display device.

  The kana-kanji conversion processing unit 8 searches the kana-kanji conversion dictionary unit 10 for a conversion character string corresponding to the input character string, and the predictive conversion processing unit 9 converts the input character string based on the input character string. The character string is searched from the predictive conversion dictionary unit 11 and the predictive conversion user dictionary unit 12. The data stored in the temporary data storage unit 3 is a predictive conversion user dictionary unit that associates a character string that has been completely erased with the part-of-speech detection unit 4 detecting a particle, a conjunction, or a punctuation mark and a confirmed character string. 12 is stored.

  The communication unit 13 includes, for example, a transmission / reception circuit, a modulation / demodulation circuit, and the like, and performs data communication by connecting to a communication network.

  The mail function unit 14 performs mail creation and mail transmission / reception.

  Next, the operation of the first embodiment will be described with reference to FIG.

  The mail function unit 14 activates the control unit 6 and activates a character string predictive conversion function for character input when editing a mail creation subject or a mail text.

  As shown in FIG. 2, when the user erases all the input character strings using the input unit 4 or the like, when the character string erase detection unit 1 detects that all the latest input character strings are erased (step S101), The control unit 6 extracts the most recently erased input character string from the text buffer unit 2 and stores it in the temporary data storage unit 3 (step S102). Subsequently, the control unit 6 reads the input character string table input by the input unit 5 (step S103), and stores the input character string in the text buffer unit 2 (step S104). The input character string is displayed on the display unit 7. Next, when the user confirms the displayed character string by operating the input unit 5 (step S105), the control unit 6 stores the confirmed character string in the text buffer unit 2 (step S106). . If the part-of-speech detection unit 4 detects a particle / conjunction / punctuation from the confirmed character string (YES in step S107), the control unit 6 temporarily stores a definite character string other than the particle / conjunction / punctuation from the text buffer unit 2. The data is stored in the data storage unit 3 (step S109). Next, the control part 6 registers the data of the temporary data storage part 3 in the prediction conversion user dictionary part 12 (step S110). Further, the control unit 6 clears the text buffer unit 2 and the temporary data storage unit 3 and ends (step S111). If the part-of-speech detection unit 4 does not detect a particle, conjunction, or punctuation mark from the confirmed character string (NO in step S107), the control unit 6 extracts the confirmed character string from the text buffer unit 2 and stores it in the temporary data storage unit 3. (Step S108) The input character string input by the input unit 5 is read again (Step S103).

As described above, according to the first embodiment, an unknown word that cannot be converted normally can be automatically registered in the predictive conversion user dictionary unit 12. Moreover, even if the character string displayed most recently does not correspond to the character string to be converted, it is possible to increase the efficiency of character input by automatically registering it in the predictive conversion user dictionary unit 12 (Example 1).
Next, the operation of Example 1 in Embodiment 1 of the present invention will be described with reference to FIGS. FIG. 3 shows a character string stored in a temporary data storage unit composed of three items of input characters, converted characters, and parts of speech. FIG. 4 shows an example of a screen displayed on the display unit 7 when inputting characters.

  The temporary data storage unit 3 includes three items: input characters, converted characters, and parts of speech. For example, when a character string “KOSUMO” is input (FIG. 4A), “KOSUMO” is stored in the text buffer unit 2. When the character string erasure detection unit 1 detects that all the character strings “Cosmo” have been erased immediately after the character string “kosmo” is input (FIG. 4B), the text buffer unit 2 “Kusmo” stored in the field is stored in the input character field of the temporary data storage unit 3 (FIG. 3A). Next, when the character string “universe” is inputted and confirmed (FIG. 4 (c)), the confirmed character string “universe” stored in the text buffer unit 2 is converted to the converted character item in the temporary data storage unit 3. (Fig. 3 (b)). Since the confirmed character string “universe” is a noun, “noun 1” is stored as a part of speech corresponding to “universe” in the part of speech item of the temporary data storage unit 3. Next, when the character “Kimi” is entered and confirmed (FIG. 4D), the confirmed character string “Kimi” stored in the text buffer unit 2 is converted into the converted character item of the temporary data storage unit 3. “Space-kun” is added to the “space” already saved in the space, and the confirmed character string “you” is added to the space (Fig. 3 (c)). Further, since the confirmed character string “you” is a noun, “noun 2” is stored as a part of speech corresponding to “you” in the item of part of speech of the temporary data storage unit 3. Next, when the character “ha” is inputted and confirmed (FIG. 4 (e)), the part of speech detection unit 4 detects that the character as a particle has been confirmed. Next, the control unit 6 registers the data stored in the temporary data storage unit 3 in the prediction conversion user dictionary unit 12. Here, since the part-of-speech classification in the temporary data storage unit 3 is noun 1 / noun 2, the conversion character strings to be registered in the predictive conversion user dictionary unit 12 are “universe-kun” and “universe”. Finally, the text buffer unit 2 and the temporary data storage unit 3 are cleared.

(Example 2)
Next, the operation of the second embodiment of the present invention will be described with reference to FIGS. FIG. 5 shows a character string stored in the temporary data storage unit 3 including three items of input characters, converted characters, and parts of speech. FIG. 6 shows an example of a screen displayed on the display unit 7 when inputting characters.

  For example, when a character string “Docken” is input (FIG. 6A), “Docken” is stored in the text buffer unit 2. Immediately after the character string “Docken” is entered, when all the character strings “Docken” are deleted (FIG. 6B), “Docken” stored in the text buffer unit 2 is temporarily stored. The data is stored in the input character field of the data storage unit 3 (FIG. 5A). Next, the character string “single” is inputted and confirmed (FIG. 6 (c)). When “RI” is deleted and “Germany” is confirmed (FIG. 6 (d)), the text buffer section 2 is stored in the converted character item of the temporary data storage unit 3 (FIG. 5B). Here, since “ri” is erased but the most recent character string is not erased, the character string erase detection unit 1 does not detect that all the latest character strings are erased, and “one person” It is not stored in the temporary data storage unit 3. Further, since the confirmed character “German” is a noun, “noun 1” is stored as a part of speech corresponding to “German” in the part of speech item of the temporary data storage unit 3. Next, when the character string “inspection” is inputted and confirmed (FIG. 6 (e)), the part of speech detection unit 4 detects that the character that is a punctuation mark is confirmed. Subsequently, the fixed character string “inspection” other than the particles, conjunctions, and punctuation marks stored in the text buffer unit 2 is stored in the “Germany” already stored in the conversion character item of the temporary data storage unit 3. “Self-examination” with “” added is stored, and “inspection” is a noun, so “noun 2” is stored as a part of speech corresponding to “inspection” in the part of speech item of the temporary data storage unit 3. (FIG. 4 (c)), because the part-of-speech detection unit 4 has detected that a character that is a punctuation mark has been determined, the control unit 6 sends the data stored in the temporary data storage unit 3 to the prediction conversion user dictionary unit 12. sign up. Here, since the part-of-speech classification in the temporary data storage unit 3 is noun 1 / noun 2, the conversion character strings to be registered in the predictive conversion user dictionary unit 12 are “self-check” and “German”. Finally, the text buffer unit 2 and the temporary data storage unit 3 are cleared.

  The present invention is a character string prediction conversion device that predicts conversion candidates for an input character string based on the input character string, the character string erasure detection unit for detecting the most recently erased input character string, and the character A character having a function of registering a character string determined after detecting that the most recent input character string has been completely erased by the sequence erasure detection unit as a conversion candidate for the all erased character string in the predictive conversion user dictionary unit Therefore, even unknown words that cannot be converted normally can be automatically registered in the prediction conversion user dictionary unit. Moreover, even if the most recent input character string does not match the character string to be converted, it can be automatically registered in the predictive conversion user dictionary unit, which is useful as a character string predictive conversion device.
