Description

  The present invention relates to a sentence input device, a sentence input method, and a sentence input program used to input various sentences such as Japanese into an information processing apparatus such as a mobile phone, a personal computer, and a word processor.

  In homes and offices, the creation of the body of an e-mail and various documents are frequently performed using an information processing device such as a mobile phone or a personal computer. Along with this, various text input devices having a function of assisting an input operation by predicting a word to be input and displaying the candidates, and various application software for assisting a similar input operation have been proposed.

  For example, as a first related technique of the present invention, a user's recently input word / phrase is stored, and when the user inputs one or several characters of a word / phrase, a word / phrase that matches the word / word forward is selected as an input word / phrase candidate. Displaying as is widely done. As a second related technique of the present invention, a template sentence and a plurality of replacement candidate sentences are stored in a storage unit, and a replacement candidate sentence corresponding to a designated short sentence designated by the user is displayed on the display unit. Has also been proposed (see, for example, Patent Document 1).

  Of these, according to the first related technology, for example, once you enter the text “I met with Yamada-kun”, the next time you enter “Yama”, “Yamada-kun” or “I met with Yamada-kun” A phrase or sentence that matches the preceding phrase such as “Yes.” Is displayed as a candidate. Therefore, the user can save the trouble of inputting the sentence “Yamada-kun ……” again.

  Further, according to the second related technique, for example, a sentence with “first” at the head, such as “Please say first” or “Drink first”, is prepared as a replacement candidate sentence. Then, when the user inputs the sentence “first”, these replacement candidate sentences are displayed and can be selected.

JP 2005-044771 (paragraph 0007)

  Such related technology is a great help when inputting sentences. However, in the second related technique, it is necessary to process the template sentence and the plurality of replacement candidate sentences and prepare them in the storage means in advance. Therefore, when trying to assist sentences other than the prepared template sentences, there is a problem that the user needs time and effort for registering these sentences in the storage means.

  In the case of the first related technology, for example, when enumerating the names of government ministers and trying to describe each person's explanation anew, if the name of the head of the name is not recalled correctly, The name cannot be displayed as input suggestions. The same applies to the case where the name of one mountain or alpine plant does not come out of memory immediately after listing and explaining a number of mountains and alpine plants that he has climbed. In such a case, it is necessary to follow the name of the corresponding mountain or alpine plant from the text you entered and find the target one, but if you search for it, the target name will appear immediately. Often does not come.

  Accordingly, an object of the present invention is to provide a text input device, a text input method, and a text input program that can input a desired text part even if a part of a phrase or text is omitted or conceptually input. There is.

  In the present invention, (a) a reference sentence storage means for storing a predetermined reference sentence, and (b) a sentence piece input means for inputting a sentence piece composed of characters constituting a part of the sentence or a phrase combined thereof. (C) a sentence part search means for searching a sentence part corresponding to the sentence piece input by the sentence piece input means from the reference sentence stored in the reference sentence storage means; and (d) a search by the sentence part search means. The sentence input device comprises sentence part display means for displaying the sentence part hit in step (i), and (e) sentence part addition means for joining the sentence part displayed on the sentence part display means to the sentence being input.

  In the present invention, (b) a sentence piece input step for inputting a sentence piece consisting of characters constituting a part of the sentence or a combination of phrases using an input device; A sentence part search step for searching a sentence part corresponding to the sentence piece input in the step from a reference sentence stored in a predetermined reference sentence area; and (c) a sentence part hit by the search in this sentence part search step The sentence input method includes a sentence part displaying step for displaying in the display area, and (d) a sentence part adding step for joining the sentence part displayed in the sentence part displaying step to the sentence being input.

  Furthermore, in the present invention, as a sentence input program, a sentence piece input process for inputting a sentence piece consisting of characters constituting a part of a sentence or a combination of words into a computer using an input device; (B) a sentence part search process for searching for a sentence part corresponding to the sentence piece input in the sentence piece input process from a reference sentence stored in a predetermined reference sentence area; and (c) a search by the sentence part search process. A sentence part display process for displaying the hit sentence part in a predetermined display area and (d) a sentence part addition process for joining the sentence part displayed in the sentence part display process to the sentence being input are executed.

  As described above, according to the present invention, since the input of a sentence is assisted based on a reference sentence such as a currently input document, a user can easily input a frequently used term. In addition, it is possible to assist the document input to some extent without requiring dictionary registration processing by the user.

  <Embodiment of the Invention>

  Next, an embodiment of the present invention will be described.

  FIG. 4 shows the structure of the text input device according to the embodiment of the present invention. The text input device 100 according to the present embodiment includes a CPU (Central Processing Unit) 101 and a control unit 103 having a memory 102 such as a ROM (Read Only Memory) or a magnetic disk that stores a control program executed by the CPU 101. ing. The control unit 103 controls each unit in the text input device 100 through a bus 104 such as a data bus.

  Among these, the communication control unit 105 is connected to a communication network (not shown) such as a LAN (Local Area Network) via the communication cable 106. The input circuit 107 inputs data from various input devices such as a keyboard 108, a mouse 109 as an example of a pointing device, a medium input unit 111, a touch panel 112, and a microphone (microphone) 113.

  Here, the medium input unit 111 is a device that inputs data from an external storage medium or storage device such as various memory cards, floppy disks, and external storage devices. The microphone 113 is used when the user inputs data by voice or gives various instructions at the time of input.

  The display control circuit 115 is connected to a display (display device) 116 such as a liquid crystal display or an organic EL (organic electroluminescence) display. The display 116 may be disposed at a plurality of locations depending on an information processing device such as a mobile phone, a PHS (Personal Handyphone System), and a smartphone (smart phone). It is also well known that a personal computer can connect a plurality of displays through an output interface circuit (not shown).

  The display 116 of this embodiment has a touch panel 112 attached to the surface thereof. Therefore, the user can appropriately select the displayed text and various buttons and input the information from the input circuit 107 to the text input device 100.

  The reference sentence storage unit 118 is a memory area for inputting a sentence to be referred to when inputting a sentence. Therefore, the reference text storage unit 118 may be configured as a single memory, or may be configured as a part of a working memory that configures a part of the memory 102. The reference text storage unit 118 is a buffer area for temporarily storing the latest text used by the user for text creation in a normal case. However, the user can capture document data such as a sentence that serves as a reference for the sentence to be input into the reference sentence storage unit 118 according to a prior setting. When an external document is used, such a document may be input to the text input device 100 using the communication control unit 105 or may be input from the medium input unit 111.

  The voice recognition unit 119 recognizes voice input by the user using the microphone 113. It is also possible to recognize voice data sent from another device (not shown) via the communication control unit 105 and input it to the reference text storage unit 118, for example. The speech recognition unit 119 includes a speech recognition dictionary as necessary.

  The grammar analysis unit 121 analyzes the grammar of the text input via the input circuit 107 and the reference text stored in the reference text storage unit 118. Then, a process of dividing the character string input from the input means such as the keyboard 108 with reference to the dictionary 122 for each constituent element of the sentence such as a noun such as a person name, a place name, a technical term, or a verb. The grammar analysis unit 121 analyzes a word or phrase to which a predetermined word or phrase such as a noun is attached when a sign such as a number is attached to the beginning or end. Further, the grammar analysis unit 121 determines whether the noun represents a singular or plural (possibility). In the case of Japanese, it is well known that plurals may be expressed even in noun forms that do not explicitly indicate pluralities.

  The dictionary 122 is used for analysis by the grammar analysis unit 121. The dictionary 122 may be composed of a system dictionary prepared in advance by the system and a user dictionary registered by the user.

  The setting data storage unit 123 is a storage unit that stores initial setting items of functions that assist the input operation of the text input device 100. The setting data storage unit 123 may be configured as a single memory, or may be configured as a part of a nonvolatile memory that configures a part of the memory 102. A default value is initially input to the setting data storage unit 123, and the user can change it as appropriate.

  The document storage unit 124 stores a document created by the text input device 100 and a document to be referenced. The created document can be output to an external device (not shown) via the communication control unit 105.

  FIG. 5 shows an example of the setting state of the setting data storage unit. This will be described with reference to FIG.

  In the setting data storage unit 123, each item (A) to (D) can be initialized. Among these items, the item (A) is a setting for whether to use the function for assisting input of matched phrases. Here, the phrase matching assistance is a function that assists related phrases in front of or behind a matching phrase as a piece of text composed of one or more characters that have been input. The input character may be a kana or romaji before conversion or a character after conversion. For example, when the user simply inputs “111” from the keyboard on the assumption that a sentence including the phrase “medium input unit 111” exists in the reference sentence storage unit 118, This function assists the input operation with the input unit 111 ”.

  (A) Item (1) sets the number of input characters to be applied. For example, when the number of input characters is “3” or more, the input operation is assisted when the user inputs three or more characters such as “111”.

  (A) Item (2) is a setting for whether or not to add a sentence, such as when a sentence fragment is input, the corresponding sentence part is added to this sentence fragment, or the entered sentence fragment is replaced with this sentence fragment. Do. For example, when “111” is input in the above-described example, an input operation (adding a sentence) that leaves “111” such as “medium input unit 111” is a process of adding a sentence. In the process of adding a sentence, it can be specified whether the sentence part is added forward or backward. For example, when “111” is input, the “medium input unit 111” becomes a case where it is added forward, and the “111 medium input unit” becomes a case where it is added backward. When the input sentence piece is set to be replaced with a sentence part, when “111” is input, it is replaced with a sentence part “medium input part”.

  (A) Item (3) is a setting for limiting the length of a sentence part to be added or replaced, that is, a document part to be joined. Here, for example, if it is set to “10” words (characters) or less, when there are some candidate sentence parts to be joined, those more than “11” words (characters) are excluded from the joining target. To do. The user does not necessarily have to make a setting to limit the number of characters.

  (A) Item (4) sets a limit on the range of sentences described before, starting from the position of the currently input sentence, as a part to be searched as a part of the sentence to be subscribed. Setting. In the present embodiment, the “search range” is determined by the number of characters, the number of sentences, the number of documents divided by reading marks, or the number of paragraphs from the starting point. In the example shown in FIG. 5, the “search range” is set by the number of sentences, and the sentence part to be subscribed is limited. For example, as shown in FIG. 5, when “-” (hyphen) is input, the reference sentence storage unit 118 limits the “search range” of the number of sentences in the currently input document. The entire reference text storage unit 118 is a candidate object.

  On the other hand, for example, when a numerical value of “50” is input, a sentence portion candidate to be subscribed is from the input position of the currently input sentence to 50 sentences before. Here, “sentence” refers to a character string having a length delimited by, for example, a punctuation mark “.”. In this way, the limitation of the search range of the candidate target is added to the description content of the sentence located ahead, for example, when one sentence is divided into different sections of several document contents. This is to prevent the currently input text from being affected.

  The item (B) is a setting as to whether or not to use the instruction word input assist function. Here, the instruction word input assistance is a function for assisting the addition of related words / phrases to the inputted instruction word composed of one or more characters. However, here, functions unique to the present invention other than the technique described as the first related technique are set. Of course, the text input device 100 of the present embodiment is free to use the first related technology together.

  The instruction word input assistance of the present embodiment is a process of adding a sentence portion indicated by an instruction word from sentence analysis when a specific word (instruction word) as shown in (1) is input. . For example, assume that the check box “this” is selected. Then, when the user inputs the phrase “this” from the keyboard 108, nouns in the previous sentence are extracted and displayed as candidates to be joined.

As an example, it is assumed that the sentence input immediately before is “a sentence piece input means for inputting a sentence piece as a character or a phrase constituting a part of the sentence”. When the user inputs “this” from the keyboard 108, for example, the next sentence portion becomes a candidate for a phrase to join.
"Text fragment input means", "Text fragment", "Character", "Phrase", "Sentence", "Part of sentence"

  Since the instruction word “this” tends to indicate a close phrase, the nouns are sequentially extracted from the end of the corresponding sentence. In the case of “these”, a sentence portion in a similar place is indicated in the same manner as “this”, but is different from a single “this” in that it is a sentence portion that is considered to be plural. In the case where the check box of “the” or “above” is turned on, the distance from the input sentence becomes less relevant.

  The item (2) (B) is a setting for whether to add the sentence portion to be entered, leaving the inputted piece of text such as “this” or replacing the whole. For example, in the above-described example of “this”, it is assumed that the sentence portion intended by the user is “sentence piece input means”. In this case, when the “add” check box is turned on, the sentence after the input becomes “this sentence piece input means”. On the other hand, when the “Replace” check box is turned on, “this” is replaced with “sentence piece input means”, so that the sentence after the input is simply “sentence piece input means”. .

  For example, it is assumed that a sentence that has been input before and exists in the reference sentence storage unit 118 is a sentence that “Kouichi Yamamoto, Yoko Yamada, and Kumiko Inoue have come”. In this case, if the user has turned on the check box of “he”, when the user inputs the word “he” from the keyboard 108, the text “Koichi Yamamoto” is replaced. “She” is excluded. The registered contents of the dictionary 122 are used to discriminate between male and female names.

  Depending on the system, for example, it is possible to set the check box of “add” to be turned on so that input assistance is performed in combination with “this” when a noun is further input. For example, when the user inputs the phrase “this circuit” from the keyboard 108, it is possible to refer to the immediately preceding sentence and replace it with the sentence “this flip-flop circuit”.

  (B) Items (3) and (4) are set when restricting sentence parts to be subscribed, as in (A) items (3) and (4). For example, when there is a possibility that the number of sentence parts corresponding to the instruction word “above” may increase, the number of sentence part candidates as a target can be limited thereby.

  (C) Setting to “same window” in item display refers to a display form in which candidates are displayed in a window in which a sentence input by the user is displayed. On the other hand, when “other window” is set, for example, when a sentence existing in the reference sentence storage unit 118 is relatively short, the whole is displayed in another window. The candidate sentence portion is highlighted by a general method for highlighting display such as coloring, underlining, font enlargement, and shading. For example, when the user designates a desired text portion using the touch panel 112, this is added to the text being input.

  The item (D) sets the location of the reference document. Normally, the “current document” that is the currently input document is set. However, if there is a related document, the location of the “reference document” may be indicated, and this may be taken into the reference sentence storage unit 118. When both the “current document” and the “reference document” are taken into the reference sentence storage unit 118, priority may be given to them, and when the amount of the “current document” sentence increases to some extent. An extended setting may be made so as to remove the reference of the “reference document”. In general, “current document” has a higher priority.

  Each item of the setting contents of the setting data storage unit 123 described above may be changed by calling it with a shortcut key of the keyboard 108 as necessary. Further, it may be possible to control on / off of a function of a specific setting item with a shortcut key.

  Next, a description will be given of a case where the text input device according to the present embodiment is used when the initial setting data is set by default or when the user has made initial settings. Here, description will be made assuming that the initial setting shown in FIG. 5 has been performed. In addition, regarding the input of text, conventionally available techniques such as the first related technique are appropriately used, but description of the use of these techniques is omitted here in order to simplify the description.

  FIG. 6 shows a state of a text input start process. This will be described with reference to FIGS. When the sentence input mode is set, the control unit 103 checks whether or not use of at least one of the matched phrase input assistance and the instruction word input assistance, which is a feature of the present embodiment, is selected (step S201). If use of at least one of the matched phrase input assistance and the instruction word input assistance is selected (Y), it is confirmed whether another window used for input assistance is necessary (step S202). If another window is not required (N), a pull-down menu to be displayed when a character is added is prepared (step S203), and the process is terminated (END). However, it is not necessary to display the option until the option is displayed.

  If another window is required as set in FIG. 5 (step S202: Y), another window for displaying options on the display 116 is prepared (step S204), and the process ends. (End) However, when the user connects an additional display to the information processing apparatus as the text input apparatus 100, another window may be displayed on the additional display.

  FIG. 7 shows a state in which another window is displayed on the display. This will be described with reference to FIG.

  The display screen 131 of the display 116 includes an input screen window 132 that creates an actual document and a reference screen window 133 that mainly displays contents that become candidates from sentences stored in the reference sentence storage unit 118. Open Recently, high-definition large-scale displays have been provided at low cost, and users can display two or more windows in parallel at a size and resolution that allows easy viewing of two or more windows.

  FIG. 8 shows a state of text input processing. This will be described together with FIGS. 4, 5 and 7. Although not shown, the user opens a new document or calls a document that is already being created, and displays the input screen window 132 on the display screen 131. In this state, the control unit 103 waits for a state in which characters are input from the keyboard 108 (step S221). Of course, the user can input voice from the microphone 113 and recognize it with the voice recognition unit 119 to input characters. Here, a case where characters are input from the keyboard 108 will be described.

  When a character is input (step S221: Y), the control unit 103 searches for a sentence part to be added to the conversion target character input so far (step S222). The search target is a sentence stored in the reference sentence storage unit 118. In this case, the reference document is “current document”. Therefore, the control unit 103 searches for the text input so far in the current document. Therefore, when the “current document” being created is called from the storage means such as the document storage unit 124 and the creation of the text is continued, the part of the “current document” created so far is stored in the reference text storage unit 118. Will be stored.

  When searching the setting contents of the setting data storage unit 123, the search for the sentence is both a match word input assist and a command word input assist. Therefore, in this example, a search is performed for both the matching phrase input assistance and the instruction word input assistance. Of these, for the matching word input assistance, a limit value for the number of input characters is set, which is “3” in this example. Therefore, in the state where the conversion target character (matching phrase) input so far is one or two characters, the matching phrase input auxiliary search is excluded and is not performed. This process is performed when there are three or more characters. For the instruction word input assistance, a search process is performed as to whether the word / phrase with a check mark in (1) of (B) appears. In the case of instruction word input assistance, the number of input characters is not limited.

  As a result of the search process in step S222, if the target sentence portion does not exist (step S223: N), a predetermined absence process is performed (step S224), and then the process returns to step S221. (Return), the next character input is in a standby state. Here, the non-existing process in step S224 means that the character string inputted so far is converted as a result of the analysis by the grammar analysis unit 121, such as the previous character string including the punctuation mark when the punctuation mark appears. Processing to exclude from the character string to be converted when it falls outside the target range. By this non-existence process, the next character to be input is processed as the first character.

  If there is a target sentence part to be subscribed for matching phrase input assistance or instruction word input assistance (step S223: Y), the target sentence part hit as a result is highlighted on the reference screen window 133 (step S225). ). Then, is there a designation input (selection) for joining the target sentence portion displayed in the reference screen window 133 to the sentence (step S226), or whether the next character is further input by the user (step S227)? Wait.

  If the user designates a predetermined part of the reference screen window 133 and selects a target sentence part to be subscribed (step S226: Y), a joining process for joining the target sentence part to the inputted sentence is performed. (Step S228). Then, the input character string so far is fixed (step S229). The determined character string is deleted from the input target, and the process returns to the character input standby state in step S221 (return).

  On the other hand, when the user inputs a character without selecting the target sentence portion to be subscribed displayed on the reference screen window 133 (step S226: N, step S227: Y), in step S227 The search process of the target sentence part by step S222 is performed with respect to the character string which added the input character. The same applies hereinafter.

  Next, the process in steps S225 and S226 will be described with a specific example.

  FIG. 9 shows the main part of the input screen window. The input screen window 132 displays the text being input. It is assumed that the user inputs a character string “this” next to “CPU 101” in the state of this input screen. As shown in FIG. 5, the instruction word input assistance is used, and a check mark is added to “this” in (1). Therefore, the grammar analysis unit 121 (FIG. 4) uses a grammatical noun that is likely to have “this” in the grammar in the latest sentence of the phrase “this” (in many cases, the same sentence and the previous sentence in many cases). Is extracted and the part is highlighted.

  FIG. 10 shows the main part of an example of the highlighted reference screen window. Here, “invention”, “embodiment”, “sentence input device”, “configuration”, “embodiment”, “sentence input device 100”, and “CPU 101” are highlighted in order by an underline. The highlighted display may be other known displays such as coloring, brightness or color inversion, and font change. Here, the word “book” in “this embodiment” or “invention” is excluded because the word “book” is not necessary for the noun following the word “this” is indicated. This is because. The reason why “embodiment” is extracted without being divided into “execution” and “form” is that it is registered in the dictionary 122 (FIG. 4) as a technical term related to patent. The user uses the touch panel 112 (FIG. 4) to select a phrase to be input from among the highlighted phrases.

  FIG. 11 shows the input status shown in the input screen window when the user selects “CPU 101” in the display state shown in FIG. In the input screen window 132, the word “CPU101” is added after the word “this” is entered.

  FIG. 12 shows the main part of the input screen window at a predetermined time point thereafter. In the input screen window 132, sentences up to “here” at the beginning of the 1235th paragraph are input.

  FIG. 13 shows the main part of the reference screen window when the user inputs the character string “111” from the state of FIG. In the reference screen window 133, the word “medium input unit 111” including the character string “111” behind is highlighted with an underline.

  FIG. 14 shows the main part of the input screen window when the user designates “medium input unit 111” on the touch panel in the display state of FIG. 13 or performs a key operation on the keyboard indicating “OK (affirmation)”. It is a thing. In the input screen window 132, a sentence part “medium input part” is added in front of the character example “111” input immediately before. As described above, the user can perform the joining process only by inputting the three or more digits for the word / phrase in which the three or more digits are added at the rear end.

  A sentence including a noun added with a kind of “prefix” such as “first” such as “first medium input unit 111A” or “second medium input unit 111B” is already input, etc. It is assumed that it is stored in the reference text storage unit 118. In this example, it is assumed that “nouns” to be extracted are “first medium input unit 111A” and “second medium input unit 111B”. In this example, both the “first medium input unit 111A” and the “second medium input unit 111B” in the reference screen window 133 when the user inputs “111” and three characters from the keyboard 108. Are extracted and highlighted. In this state, the user may select one of these, but if the fourth character “A” or “B” is additionally input (step S227: Y in FIG. 8), the search for the target sentence portion is performed. The process is performed for four characters (step S222 in FIG. 8). As a result, when “A” is additionally input, only the portion of “first medium input unit 111A” is highlighted, and when “B” is additionally input, “second medium” is highlighted. Only the portion of “input section 111B” is highlighted. By increasing the number of characters to be input in this way, it is possible to limit the sentence portions that are candidate targets.

  FIG. 15 shows the main part of the input screen window when the user inputs a three-digit number at the location where the user explains the document code described above. In the input screen window 132, for example, the number “100” is input. The number “100” is a number assigned to the “character input device” as shown in the input screen window 132 of FIG.

  FIG. 16 shows the main part of the input screen window after the input numbers are replaced. In the input screen window 132, the word “character input device” is added after the number “100”. However, in order to add a phrase corresponding to the number after the corresponding number in this way, the setting content of (A) (2) of the setting data storage unit 123 shown in FIG. It is necessary to change to a state where words are added to the back.

  In the example shown in FIG. 16, when there is a promise in the document such as placing a blank or a colon (:) between a number and a word describing the number, the setting data storage unit 123 does so. It is sufficient to add various functions. Of course, the user may manually insert a blank or a colon (:) at the corresponding location.

  As described above, according to the present embodiment, the words input by the user and captured in the reference screen window 133 can be utilized for new input processing without the need for performing word registration step by step. As a result, not only the text input operation is simplified, but also the words and phrases specified by numbers and symbols can be used in association with each other. In addition, even if you forget a specific word or phrase in the middle of entering it, you can enter a command word that specifies a specific term such as "this" or "he" or a word that is a generic name. It is possible to read a word such as a phrase or a name that replaces these and perform a replacement process. In addition, when the user inputs “this” or “he”, if the next word / phrase is input without performing the joining process, the search processing for the next target sentence portion is started. Therefore, the user can execute a process of adding the display contents to the currently input sentence only when the target sentence portion to be displayed is displayed.

  The present invention is not limited to the embodiment described above, and various modifications can be made.

  FIG. 17 shows an example of a pull-down menu for selecting a word to join on the input screen only. Some text input devices may not have a touch panel on the display. In such a case, the number assigned to the word or phrase to be joined may be input by a key operation, or a selection operation may be performed by designating with a cursor (not shown). You may input with voices, such as "ichi" and "knee". Of course, instead of displaying the pull-down menu, a predetermined next candidate key may be pressed to display the candidates in order on the display screen, and may be selected when a desired candidate is displayed.

  In addition, in the example shown in FIG. 17, numbers corresponding to these are added to the first candidate and the second candidate nouns. It is also possible to display both of the undisplayed items so that one of them can be selected.

  Further, the reference text storage unit 118 may store a document that serves as a reference for input, such as a document related to the document to be input this time, or the document to be input this time and these documents may coexist. . Furthermore, the priority and weight of these documents may be set to discriminate the display order and form.

  Further, in the embodiment, a plurality of instruction words are prepared in advance and can be selected with check boxes as the words for assisting the instruction word input in FIGS. 5B and 5A, but the user can select other than these. You may be able to add words.

  Further, in the embodiment, a word and phrase corresponding to numbers such as “100” and “101” is searched for and used for input processing. However, an ambiguous search may be performed. For example, when the user inputs “10−”, the terms “100” to “109” are displayed as candidates, such as “text input device 100”, “memory 102”, “control unit 103,“ bus 104 ”. Of these, a desired one may be selected. Here, “−” means that the number is not limited.

  Similarly, after the user lists and inputs the names of some section managers, if he enters "section manager" or "-section manager", in addition to just "section manager", "Yamada section manager", "Kawahara section manager", etc. The section managers who have already been input may be listed as input candidates. Of course, by storing a list of section managers in the reference text storage unit 118, each section manager can be called and input. Similarly, the input of place names such as mountains and rivers can be easily performed according to the present invention. Similarly, by inputting “vegetable”, it is possible to list the names of vegetables such as chingensai and cabbage that have already been entered as candidates. In this case, a classification table such as “vegetables” and “fruits” may be stored in the dictionary 122. “Fruit” is synonymous with “fruit”. By associating words having the same meaning in the dictionary 122, the search function can be enhanced.

  When there are some candidates as described above and the initial part of the title is similar, a desired candidate can be selected by inputting characters up to the part where the difference is known. In the situation where multiple names of section managers and assistant managers are entered, if you simply enter “section manager”, all of these will be displayed as candidates, but if you enter up to “section manager”, only the assistant manager name will be considered as candidates. Can be selected. Of course, it is also possible to enter a setting that excludes listing of assistant manager names by entering “section manager only”.

  For the candidates that appear, the priority order may be set in consideration of various circumstances such as the size of the gap in the context such as the number of sentences and the number of paragraphs from the starting point of the currently entered sentence to the corresponding sentence part. Good. In this case, it is effective to be able to select a higher priority first.

  In the embodiment, the reference screen window 133 is provided, and the referred text including the text portion corresponding to the input text fragment is displayed in a relatively long text. However, the present invention is not limited to this. There are cases where the display area of the reference screen window 133 is small or there are a plurality of text parts to be referred to and these are scattered in one document and cannot be accommodated in one reference screen window 133 at a time. In such a case, only a candidate sentence portion may be displayed like a pop-up menu like the pull-down menu of FIG. Of course, if the sentence displayed in the input window includes candidate sentence parts, both may be displayed in the same window (or display screen). It is also possible to divide and display the window (or display screen).

  Further, in the embodiment described above, Japanese language processing has been described, but it is natural that the present invention can be similarly applied to other languages.
