Description

  The present invention relates to a character input device and a character input method in an information processing device.

  In general, a character input method in a mobile phone device is a method in which a line of 50 sounds is assigned to each of the numeric keys “1” to “0” and the assigned line changes depending on the number of times the key is pressed. Adopted. In this method, in order to input “o”, it is necessary to press the “1” key five times. Therefore, this method has a problem that the number of key presses increases explosively as the number of input characters increases.

  Therefore, in order to reduce the number of times of pressing, a predictive input method that predicts a word that matches forward with a hiragana being input is becoming common. In the prediction input method, the mobile phone device often has a function of predicting a word following the word from the input words (hereinafter, connection prediction input method).

  In this connection prediction input method, the mobile phone device determines connection adjunct word candidates according to the part of speech information assigned to each selected and confirmed word.

  The part of speech refers to a noun, a verb, an adjective, an adjective verb, and the like, and the verb has a utilization form such as upper one stage utilization, lower first stage utilization, and five stage utilization. An adjunct is a word that cannot be a phrase by itself, such as a particle or auxiliary verb.

  An example of such a connection prediction input method is described in Patent Document 1.

  The character prediction input method described in Patent Document 1 includes at least an input unit, an output unit, a control unit, a prediction control unit, a predicted independent word dictionary search unit, a predicted auxiliary word dictionary search unit, a predicted independent word dictionary, and a predicted auxiliary word. Consists of a dictionary.

  The input unit is a keyboard, mouse, pen input device, or the like, and captures command inputs such as input of character strings, editing instructions such as cursor movement, insertion and deletion of character strings, next candidate display, and candidate selection.

  The output unit has a display or the like, and displays an input character string, a predicted word, and a connected auxiliary word candidate connected to the selected word.

  The control unit analyzes the information fetched from the input unit, sends the information to each processing unit, conversely edits the information from each processing unit, and outputs the information to the output unit.

  The prediction control unit receives the reading character string via the control unit, and controls the prediction independent word dictionary search unit and the prediction auxiliary word dictionary search unit to extract independent word candidates and auxiliary words following the independent word. Independent words are words that can become phrases by themselves, including endings.

  The prediction control unit outputs the extracted independent word candidate and the attached word following the independent word to the output unit via the control unit.

  The predicted independent word dictionary search unit searches for an independent word in which the reading character string and the reading of the dictionary heading match completely or in front while referring to the predicted independent word dictionary, and returns the result to the prediction control unit.

  The predicted ancillary dictionary search unit searches for an ancillary word following the predicted independent word based on the part of speech of the independent word while referring to the predicted ancillary word dictionary, and returns the search result to the prediction control unit.

  The predicted independent word dictionary is a dictionary that defines independent word readings, kanji kana notation for independent word readings, part of speech of independent words, and the like.

  The predictive adjunct dictionary is a dictionary that defines the types of parts of speech and the adjuncts that follow the inflected form for each part of speech.

  The character prediction input method described in Patent Document 1 including these components generally operates as follows.

  When the control unit receives the reading character string from the input unit, the control unit adds the character to the prediction target reading character string buffer and activates the prediction control unit. The prediction control unit sends the character string information in the prediction target reading character string buffer to the prediction independent word dictionary search unit. The predicted independent word dictionary search unit searches for an independent word in which the reading character string and the reading of the dictionary heading match completely or in front while referring to the predicted independent word dictionary, and returns the result to the prediction control unit. When the prediction control unit receives the list of independent word search results, the prediction control unit sends the independent words of the search results to the prediction ancillary word dictionary search unit. The predicted ancillary word dictionary search unit searches the subsequent ancillary words based on the predicted part of speech of the independent word while referring to the predicted ancillary word dictionary, and returns the search result to the prediction control unit. When the prediction control unit receives the search result of the auxiliary word for the independent word list of the search result, the auxiliary word of the search result is associated with each independent word in order of use frequency, stored in the prediction candidate buffer, and the control unit controls the control word. return. The control unit receives the contents of the prediction candidate buffer and performs display control of independent words and attached words.

  As a result, for example, when the user inputs a reading character string of “done”, an independent word such as “done, finished is a desk” is displayed in the prediction candidate window on the screen. When the user selects “Done” on the screen with a cursor or the like, an auxiliary word adjunct such as “Masu, Ta, was” is displayed in the ending window. The user can select an appropriate ending from the attached words.

  The above description of the operation is the minimum operation content related to the present invention, and the gazette has a user expression search unit in addition to the predicted independent word dictionary search unit, and a kana-kanji conversion function for a read character string is prepared. However, their explanation is omitted.

  In the prediction input method described in Patent Document 1, the attached words are connected in order of use frequency and displayed as prediction candidates based on the part-of-speech information of the independent words selected and confirmed. For this reason, even when creating a business document in honorific style, there is a problem that frequently used auxiliary words that are used only in colloquial style emails are displayed at the top.

JP 2000-48018

  In the above-described character input device of Patent Document 1, when creating a business document in honorific style (respected mode), the connected word prediction candidates used in the honored mode are not preferentially displayed, resulting in reduced document creation efficiency. There was a problem to do.

  The reason for this is that when a word for a reading character string is selected and confirmed, connection adjunct word prediction candidates for the word are always displayed in the order of use frequency of the connection adjunct words.

  The object of the present invention is to solve the above-mentioned problem that “the connected adjunct word prediction candidates used in the honorific mode are not displayed preferentially when creating a business document in honorific mode (respective mode)”.

A predicted word candidate is searched from the prediction word database based on a character string input at the time of character input, the searched predicted word candidate is displayed on the display unit, and one of the displayed predicted word candidates is designated. Then, a connected ancillary word candidate is selected from the connected ancillary word database based on the specified predicted word, and if the setting unit is set to a predetermined expression mode, among the selected connected ancillary word candidates, An attached word suitable for a predetermined expression mode is preferentially displayed on the display unit.

  The character input method and the character input method in the information processing apparatus according to the present invention, for example, when creating a business document in honorific style (respected mode), preferentially display a connected word prediction candidate suitable for the respected mode, This has the effect of improving document creation efficiency.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a first embodiment of the present invention.

  The character input device according to the present embodiment is assumed to be a mobile phone.

  Referring to FIG. 1, the character input device according to the present embodiment includes an input unit 1, a display unit 2, a predicted word candidate display control unit 3, a connected auxiliary word candidate display control unit 4, a prediction word database 5, and a connected auxiliary word. The database 6 includes a candidate output storage unit 7 and a mode storage unit 8. However, in FIG. 1, a communication control unit and a voice input / output unit of a wireless communication unit necessary as a mobile phone are omitted.

  The input unit 1 is a numeric keypad, a control key, or the like, and has a function of inputting commands such as input of a character string, movement of a cursor, editing instruction such as insertion and deletion of a character string, next candidate display, and candidate selection.

  The display unit 2 includes a display, and displays an input character string, a predicted word list, a selected and confirmed word, and a connected attached word candidate list connected to the selected and confirmed word.

  When a character is input to the input unit 1, the predicted word candidate display control unit 3 receives the character from the input unit 1, and adds the character to an internal character string buffer (not shown). The predicted word candidate display control unit 3 displays the character string in the character string buffer on the display unit 2 and searches for the predicted word candidate from the prediction word database 7 based on the character string in the character string buffer. This search method will be described later. Note that not only characters but also punctuation marks, for example, are input from the input unit 1. The predicted word candidate display control unit 3 determines whether the character is valid or not, and adds the character to the character string buffer only for the character.

  Then, the predicted word candidate display control unit 3 displays a list of searched predicted word candidates on the display unit 2, and waits for the user to select one of the lists. The predicted word candidate display control unit 3 detects that selection has been performed by receiving a selection key pressing signal in the input unit 1. When the user presses the confirm key instead of the selection key, the predicted word candidate display control unit 3 confirms the input character string and waits for the character string input.

  When the prediction word is selected by the user, the prediction word candidate display control unit 3 converts the displayed character string into the kanji notation of the selected word and displays it, and connects the part of speech of the selected prediction word. It is passed to the attached word candidate display control unit 4.

  The connected adjunct word candidate display control unit 4 searches the connected adjunct word database 6 based on the part of speech of the word passed from the predicted word candidate display control unit 3. This search method will be described later. Then, the connected auxiliary word candidate display control unit 4 stores the searched list of connected auxiliary word candidates in the candidate output storage unit 7. Next, if the respect mode is not set in the mode storage unit 8, the connected auxiliary word candidate display control unit 4 displays the searched connected auxiliary word candidate on the display unit 2 as it is, and among the connected auxiliary word candidates, Wait for one of these to be selected by the user. Details of the mode storage unit 8 will be described later. The connected accessory word candidate display control unit 4 detects that selection has been performed by receiving a selection key pressing signal in the input unit 1. When the user presses the confirmation key instead of the selection key, the connection adjunct word candidate display control unit 4 confirms the displayed word, returns control to the predicted word candidate display control unit 3, and waits for input of a character string. To do.

  When one of the connected auxiliary word candidates is selected by the user, the connected auxiliary word candidate display control unit 4 displays the selected connected auxiliary word following the displayed word. Then, the connection adjunct word candidate display control unit 4 searches the connection adjunct word database 8 based on the part of speech of the selected connection adjunct word, and performs a selection process of connection adjunct word candidates following the connection adjunct word.

  The connected auxiliary word candidate display control unit 4 returns the control to the predicted word candidate display control unit 3 and waits for input of a reading character when one of the connected auxiliary word candidates is not selected by the user and the confirmation key is pressed. And

  Next, the connected auxiliary word candidate display control unit 4 rearranges the connected auxiliary word candidates stored in the candidate output storage unit 7 if the respect mode is set in the mode storage unit 8. This rearrangement is performed so that the connected word candidates used in the honorific mode are higher. Details of the rearrangement will be described later. The connected auxiliary word candidate display control unit 4 displays the rearranged connected auxiliary word candidates on the display unit 2 and waits for one of the connected auxiliary word candidates to be selected by the user. The subsequent processing of the connected attached word candidate display control unit 4 is the same as the case in which the respect mode is not set in the mode storage unit 8 and the user waits for one of the connected attached word candidates to be selected by the user. It is.

  Next, the prediction word database 5 and its search method will be described.

  The prediction word database 5 has a prediction word dictionary therein.

  FIG. 2 is a diagram illustrating an example of a prediction word dictionary. Referring to FIG. 2, the prediction word dictionary is composed of items of independent word reading, notation, frequency of use, and part of speech.

  The predicted word candidate display control unit 3 searches for a word in which the reading character string in the character string buffer and the reading of the dictionary headline completely match or forward match.

  For example, if the input character string is “Kaku”, the predicted word candidate display control unit 3 extracts “writing” as the notation.

  Next, the connection adjunct database 6 and its search method will be described.

  The connection adjunct word database 6 has an adjunct word dictionary connected inside.

  FIG. 3 is a diagram illustrating an example of a connection attached word dictionary. Referring to FIG. 3, the connected adjunct dictionary is composed of parts of speech and adjuncts corresponding to parts of speech. In FIG. 3, the connection adjunct dictionary shows, as an example of the part of speech, a five-step verb-unformed form, a five-step verb-combined form, a five-step verb-end / combined form, and a five-step verb-assumed / instruction form The example of an appendix in the part of speech is shown.

  Based on the part of speech of the word passed from the predicted word candidate display control unit 3, the connected ancillary word candidate display control unit 4 searches for a subsequent ancillary word while referring to the connected ancillary word dictionary.

  For example, it is assumed that the user selects “write” described above from the predicted word candidates displayed by the predicted word candidate display control unit 3. In this case, the part-of-speech of “write” is a five-step verb-end / union form. Therefore, the connection adjunct word candidate display control unit 4 lists the adjuncts corresponding to the five-step verb-termination / combined form in FIG. 3 as the adjuncts that follow from the connection adjunct word dictionary.

  Next, the candidate output storage unit 7 is a place where the connection auxiliary word candidate display control unit 4 stores a list of searched connection auxiliary word candidates. For example, the candidate output storage unit 7 is predetermined in a RAM (Random Access Memory). It may be an area.

  Next, the mode storage unit 8 is a place for storing a mode when the character input device according to the present embodiment is used. The mode storage unit 8 is a rewritable memory, and an SRAM (Static Random Access) in which information is not lost even when the power is turned off. Memory) or the like.

  Note that the mode includes a honorary mode used in honorific styles such as business mail, and a normal mode used in colloquial style emails. In this embodiment, it is assumed that “1” is set in the mode storage unit 8 during the honor mode. Moreover, in this embodiment, the setting method of the mode information of the mode memory | storage part 8 is not ask | required. For example, a method in which SRAM with mode information set in advance is exchanged from the outside, a method in which a command is input from the input unit 1, or a method in which the SRAM is set in the second embodiment is shown. An automatic setting method may be used. Further, it is assumed that the mode storage unit 8 is reset, that is, “0” is set when the system of the present embodiment is started up.

  Next, rearrangement of the connected auxiliary word candidates stored in the candidate output storage unit 7 in the connected auxiliary word candidate display control unit 4 in the honor mode will be described.

  As described above, the connected auxiliary word candidate display control unit 4 rearranges the connected auxiliary word candidates stored in the candidate output storage unit 7 when the mode storage unit 8 is set to the respect mode.

  The order of the attached words stored in the connected attached word dictionary is set at the time of shipment from the factory, and is set without being particularly aware of the use mode. Accordingly, the candidate output storage unit 7 stores the order of the attached words stored in the connected attached word dictionary. This state is referred to as a normal mode in the present embodiment. In the normal mode, the adjunct words used in the honor mode are randomly mixed.

  If the honorary mode is set in the mode storage unit 8, the connected accessory word candidate display control unit 4 rearranges the attached words used in the honorable mode so as to be higher.

  For example, when the above-mentioned “write” is selected, the appendix corresponding to the five-step verb-end / combined form in FIG. 3 is an appendix list in the normal mode.

  FIG. 4 is a diagram showing an example of rearranging the adjuncts used in the honorific mode in the five-stage verb-termination / community correspondence adjuncts of FIG.

  In the present embodiment, there is no limitation on a method for identifying whether an auxiliary word is an auxiliary word that is used in the honorific mode or an auxiliary word that is not used in the honorary mode, which is necessary for the rearrangement.

  For example, as shown in FIG. 5, a flag is attached to an attached word used in the honorific mode in the attached word dictionary shown in FIG. 3 at the time of factory shipment, and the connected attached word candidate display control unit 4 has a flag. Alternatively, a method may be used in which an attached word is determined as an attached word used in the honorific mode. In FIG. 5, “1” added to the “respectful” column is a flag. FIG. 4 described above is a case where the connection adjunct word candidate display control unit 4 rearranges the adjuncts with this flag in the upper rank in the adjuncts corresponding to the five-step verb-termination / combined form in FIG. FIG.

  Next, a display example of the prediction word candidate in the prediction word candidate display control unit 3 and a display example of the connection auxiliary word candidate in the connection auxiliary word candidate display control unit 4 will be described.

  FIG. 6 is a diagram illustrating a display example of a predicted word when the character “Kuru” is input and a connected auxiliary word candidate in the normal mode.

  On the left side, when “Kuru” is input, the predicted word candidate display control unit 3 searches the prediction word dictionary and displays a list of searched predicted word candidates on the display unit 2. On the right side, when “coming” is selected, the connection adjunct word candidate display control unit 4 searches for an adjunct word while referring to the connection adjunct word dictionary, and the connection in the found normal mode is attached. This is an example in which a list of word candidates is displayed on the display unit 2. Note that “coming” is the same as “writing” described above, and its part of speech is a five-step verb-end / union form.

  FIG. 7 is a diagram showing a display example of a predicted word when a character “Kuru” is input and a connected auxiliary word candidate in a respect mode.

  On the left side, when “Kuru” is input, the predicted word candidate display control unit 3 searches the prediction word dictionary and displays a list of searched predicted word candidates on the display unit 2. When “coming” is selected on the right side, the connected adjunct word candidate display control unit 4 searches for connected adjunct words while referring to the connected adjunct dictionary, and ranks the connected adjunct words used in the honorific mode. This is an example of rearranging and displaying on the display unit 2.

  As can be seen from FIG. 7, the connected ancillary words used in the honored mode are preferentially displayed in the connected ancillary word candidates in the respected mode.

  Next, FIG. 8 is a flowchart for explaining the operation of the present embodiment.

  (Step 1) When a character is input to the input unit 1, the predicted word candidate display control unit 3 inputs the character from the input unit 1. Note that S1 in the figure refers to step 1 and so on.

  (Step 2) The predicted word candidate display control unit 3 receives the character from the input unit 1, and adds the character to an internal character string buffer (not shown). The predicted word candidate display control unit 3 displays the character string in the character string buffer on the display unit 2 and searches for the predicted word candidate from the prediction word database 5 based on the character string in the character string buffer.

  (Step 3) The predicted word candidate display control unit 3 displays a list of searched predicted word candidates on the display unit 2, and waits for the user to select one of the lists.

  (Step 4) Upon receiving the selection key signal for selecting the prediction word, the predicted word candidate display control unit 3 converts the displayed character string into the kanji notation of the selected word, displays it, and selects it. The part of speech of the prediction word is connected and passed to the attached word candidate display control unit 4.

  When the predicted word candidate display control unit 3 receives the confirmation key signal, the predicted word candidate display control unit 3 confirms the input character string and waits for the character string input.

  (Step 5) The connected auxiliary word candidate display control unit 4 searches the connected auxiliary word database 8 for the connected auxiliary word candidates based on the part of speech of the word passed from the predicted word candidate display control unit 3.

  (Step 6) The connected auxiliary word candidate display control unit 4 stores the searched list of connected auxiliary word candidates in the candidate output storage unit 7.

  (Step 7) The connected attached word candidate display control unit 4 determines whether or not the honor mode is set in the mode storage unit 8.

  (Step 8) If the honorary mode is set in the mode storage unit 8, the connection accessory word candidate display control unit 4 rearranges the connection auxiliary word candidates stored in the candidate output storage unit 7, and the step Fly to 9. If the respect storage mode is not set in the mode storage unit 8, the connected attached word candidate display control unit 4 jumps to step 9.

  (Step 9) The connection auxiliary word candidate display control unit 4 displays the searched connection auxiliary word candidates on the display unit 2, and waits for one of the connection auxiliary word candidates to be selected by the user.

  (Step 10) When the connection key word candidate display control unit 4 receives the selection key signal, it jumps to Step 5, and when it receives the confirmation key signal, it confirms with the input word, jumps to Step 1, Wait for character string input.

  As can be seen from the above description, the character input method in the character input device and the information processing apparatus according to the first embodiment is preferential to the adjunct word prediction candidate suitable for the respect mode when creating a document in the respect mode. The document creation efficiency is improved.

  The reason for this is that, in this embodiment, when a prediction word is selected, if the honor mode is set in the mode storage unit 8, the connected auxiliary word candidate used in the honor mode is higher. This is because sorting is performed.

  Next, FIG. 9 is a block diagram showing a second embodiment of the present invention.

  Referring to FIG. 2, the present embodiment includes an input unit 1, a display unit 2, a predicted word candidate display control unit 3, a connected auxiliary word candidate display control unit 4-1, a prediction word database 5, and a connected auxiliary word database 6. The candidate output storage unit 7 and the mode storage unit 8 are included. Furthermore, the present embodiment includes a mode setting control unit 9 and a normal candidate counter 10.

  In this block diagram, the blocks having the same reference numerals as the blocks in FIG. 1 described in the first embodiment have the same functions, and thus the description thereof is omitted.

  In the present embodiment, the connection adjunct dictionary in the connection adjunct database 6 is flagged as an adjunct used in the respect mode at the time of factory shipment, as described in FIG. 5 of the first embodiment. It shall be attached. Similarly to the connected adjunct word candidate display control unit 4, the connected adjunct word candidate display control unit 4-1 determines that the attached word with the flag is an attached word used in the respect mode.

  The connection adjunct word candidate display control unit 4-1 is mostly the same function as the connection adjunct word candidate display control unit 4. The difference will be described with reference to the flowchart of FIG. 8 for easy understanding.

  When one of the connected auxiliary word candidates is selected by the user in step 10 of the flowchart of FIG. 8, the connected auxiliary word candidate display control unit 4 jumps to step 5, whereas the connected auxiliary word candidate display control unit 4. −1 is a point where the mode setting control unit 9 is activated. In that case, the connected auxiliary word candidate display control unit 4-1 activates the mode setting control unit 9 with information indicating whether or not the selected auxiliary word has a flag.

  That is, in step 10 of the flowchart of FIG. 8, when one of the connected auxiliary word candidates is selected by the user, the connected auxiliary word candidate display control unit 4-1 skips to step 5 before the mode setting control unit 9. Thus, mode setting control based on the selected attached word is performed.

  When the mode setting control unit 9 is activated from the connection adjunct word candidate display control unit 4-1, the mode setting control unit 9 determines whether the selected adjunct word is a respect mode candidate. That is, when the mode setting control unit 9 receives information that the attached word selected from the connected attached word candidate display control unit 4-1 has a flag, the selected attached word is a candidate mode candidate. It is considered. On the other hand, when the mode setting control unit 9 receives information that the attached word selected from the connected attached word candidate display control unit 4-1 has no flag, the selected attached word is the normal mode candidate. It is considered.

  The mode setting control unit 9 sets “1” in the mode storage unit 8 when the selected attached word is a respect mode candidate, and sets the mode as the respect mode. Then, the mode setting control unit 9 resets the normal candidate counter 10 and jumps to step 5 in the flowchart of FIG.

  When the selected attached word is a normal mode candidate, the mode setting control unit 9 updates (+1) the normal candidate counter 10, and if the value of the normal candidate counter 10 is larger than 3, “0” is set in the mode storage unit 8 to set the normal mode. The mode setting control unit 9 jumps to step 5 in the flowchart of FIG. 8 if the value is 3 or less even after updating the normal candidate counter 10.

  The normal candidate counter 10 is a counter that is used by the mode setting control unit 9 and stores the number of times that the attached word of the normal mode candidate is selected, and is reset at the time of transition to the respect mode.

  Next, FIG. 10 is a flowchart showing the operation of the present embodiment.

  Since the same step numbers as those in FIG. 8 have the same operation, description of S1 to S10 is omitted.

  (Step 11) When the mode setting control unit 9 is activated from the connection adjunct word candidate display control unit 4-1, it determines whether or not the selected adjunct word is a respect mode candidate.

  (Step 12) When the selected attached word is a spectator mode candidate, the mode setting control unit 9 sets “1” in the mode storage unit 8 to set the spectator mode.

  (Step 13) The mode setting control unit 9 resets the normal candidate counter 10 and jumps to Step 5.

  (Step 14) If the selected attached word is a normal mode candidate, the mode setting control unit 9 updates the normal candidate counter 10 (+1).

  (Step 15) The mode setting control unit 9 determines whether or not the value of the normal candidate counter 10 is greater than 3, and if the value of the normal candidate counter 10 is 3 or less, the process jumps to Step 5. The comparison value “3” shown in the present embodiment is an example and is not limited to this value.

  (Step 16) If the value of the normal candidate counter 10 is greater than 3, the mode setting control unit 9 resets the mode storage unit 8 and jumps to Step 5.

  As described above, the character input method in the character input device and the information processing apparatus according to the second embodiment is such that, when a document is created in the honor mode, the connected word prediction candidates suitable for the honor mode are preferentially displayed. As a result, the document creation efficiency is improved.

  The reason for this is that, in this embodiment, when a prediction word is selected, if the honor mode is set in the mode storage unit 8, the connected auxiliary word candidate used in the honor mode is higher. This is because sorting is performed.

  In addition, the present embodiment has an effect that switching between the honor mode and the normal mode can be automatically performed.

  The reason is that the mode setting control unit 9 determines the mode based on whether the selected ancillary word is a respected mode candidate or a normal mode candidate, and, in the case of a normal mode candidate, the value of the normal candidate counter 10. This is because the mode is set in the mode storage unit 8.

  The information processing device to which the character input device of the above-described embodiment is applied is not limited to a mobile phone, and may be a general information processing device such as a PC having a character input function.

  In the above embodiment of the present invention, the mode storage unit 8 (FIGS. 1 and 9) is used as means for setting a predetermined expression mode as the character input operation mode. A predetermined expression mode may be set by setting.

  Further, as the predetermined expression mode, the honor mode in the case of creating a sentence in honorific style and the normal mode in the case of creating a sentence in colloquial tone have been described as examples, but other modes may be used. For example, dialect mode and standard language mode may be set as the predetermined expression mode. In this case, the connected adjunct words in the dialect mode expression format are stored as a connected adjunct word database that stores adjunct words that can be character strings connected to the predicted words.

  Further, in the connection display control means for preferentially displaying an adjunct word suitable for a predetermined expression mode on the display unit, in the above-described embodiment, the adjunct word connection adjunct word candidate is rearranged so as to be higher. It was. However, in addition to the rearrangement, connected adjunct word candidates may be highlighted and displayed with different colors.

  Moreover, the prediction word database that stores information on the predicted word for the input character string and the connected word database that stores the attached word that can be a character string connected to the predicted word may be rewritable by the input unit. The contents of these databases may be downloaded or rewritten via communication means.

  Furthermore, the input unit may be a touch panel formed integrally with the display unit.

It is a block diagram which shows the 1st Embodiment of this invention. It is a figure which shows an example of the word dictionary for prediction. It is a figure which shows an example of a connection attached word dictionary. It is a figure which shows the example at the time of rearranging so that the adjunct used in a honorific mode may come to the upper rank among the adjuncts corresponding to a five-step verb-end / combined form. It is a figure which shows the case where the flag is attached to the adjunct word used by the honorific mode in an adjunct dictionary.
