DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a text input method used in various information processors such as word processors and personal computers.

[0002]

2. Description of the Related Art Heretofore, kana-kanji conversion has been widely used as a text input method. Kana-Kanji conversion is a method of converting a Kana character string or a Roman character string into a Kanji-Kana-mixed character string using at least a Kana key or an English character key, a conversion instruction key, and a confirmation instruction key and inputting the same. For example, a method for realizing the method is described in “Kana-Kanji Conversion Algorithm” (Saito and Kawata, IEICE Journal, Vol. 70, No. 8, 19)
1987), and its operation method is described in “Ichitaro ver.
Version) "(Just System, 1989).

[0003] Based on the kana-kanji conversion, the input efficiency is improved by further combining the following sentence input methods.

The first method is to preliminarily register a certain character string so that the character string can be input using only the first one or two characters. For example, "Happy New Year" is registered in advance by using "A" as a key, and by simply pressing the kana character "A" and a conversion instruction key, "Happy New Year" can be input. Such a method is disclosed in
No. 116835, "Japanese input device with abbreviated input function", Japanese Patent Application Laid-Open No. Sho 60-65320, "Kana-kanji conversion device", Japanese Patent Publication No. 1-312929, "Kana-kanji conversion device",
This is described in, for example, Japanese Patent Publication No. 1-31230, "Short Conversion Method in Kana-Kanji Conversion Device".

[0005] The second method is almost the same as the first method, except that a specific key or a specific character combination is used instead of the first and second characters. This method is described in JP-A-61-21770, "abbreviation selection input method", and JP-A-61-279974, "Document creation device".

The third method is based on reading some kanji and words, and preliminarily associated idioms, idioms, examples,
This is to input a transliteration sentence. This method
Japanese Patent Application Laid-Open No. 62-237568, "Document Input Device", Japanese Patent Application Laid-Open No. 63-17069, "Document Creation Device", Japanese Patent Application Laid-Open No. 63-298564, "Japanese Document Creation Device" and the like are described.

A fourth method is to refer to a synonym dictionary and convert a word to its synonym. This method is disclosed in Japanese Patent Application Laid-Open No. Sho 59-197923, "Sentence Creation Apparatus", Japanese Patent Application Laid-Open No. Sho 59-230331, "Word Processor Device", Japanese Patent Application Laid-Open No. 60-20230, "Word Processor Device", and Japanese Patent Application Laid-Open No. 60-20231. It is described in the official gazette “word processor device” and Japanese Patent Application Laid-Open No. Sho 60-142468 “text creation device”.

[0010] The above-mentioned four methods use a conversion operation similar to the Kana-Kanji conversion, so that a sentence can be easily input without necessarily typing the reading as it is. What improves the input efficiency by these methods is an expression element that bears a concept in a sentence, such as an independent word, an idiom, or an idiom. In other words, in the process of creating a sentence, when the concept to be input in advance is clear as a concept, the concept is to be easily input.

[0009]

On the other hand, for the expression elements that carry the concepts, adjuncts (particles / auxiliary verbs or auxiliary collocations that are in charge of them) are used as elements that express the relationship between those concepts. is there. By this appendix part,
Various expressions and subtle emotions can be added. Therefore, when creating a sentence, after inputting and confirming only the independent word part, it is necessary to consider the part of the auxiliary word and input it again, or to add the auxiliary word to the independent word and enter it once. , Changing to another auxiliary word, etc. are frequently performed.

In the basic input method using kana-kanji conversion, as described in the above-mentioned document, the analysis processing is performed in units of phrases, and it is also in units of phrases that the user can select a candidate. This is because the conversion algorithm is designed based on the grammar related to the phrase structure.
Since the basic form of a clause is an independent word followed by an appendix, if you try to enter a string that starts with the appendix,
For example, a character string of an attached word may be forcibly interpreted as an independent word and converted (for example, the particle “ha” is converted to “leaf” or “teeth”).

The above four methods used in combination with the kana-kanji conversion are also replaced by a unit of a phrase as a unit of candidate selection, which is associated in advance. It is not a method to change only the part of the appendix which is a part.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method of inputting a sentence in which it is easy to appropriately select an accessory word portion, or to add or modify an accessory word.

[0013]

[Means for Solving the Problems]

According to a first aspect of the present invention, there is provided a sentence input capable of converting a kana character string or a roman character string into a kanji-kana mixed character string and inputting the character string using at least a kana key or an alphabet key, a conversion instruction key, and a determination instruction key. In the method, in a state where the conversion result of the kana character string or the Roman character string is selectable by tapping the conversion instruction key, and a second conversion instruction key different from the conversion instruction key is pressed, A character string or one of a group of character strings registered in advance at the position immediately after the candidate selection target
This is a sentence input method characterized by inputting one character.

According to a second aspect of the present invention, there is provided a text input capable of converting a kana character string or a roman character string into a kanji / kana mixed character string and inputting the character string using at least a kana key or an alphabet key, a conversion instruction key and a determination instruction key. In the method, in a state where the conversion result of the kana character string or the Roman character string is selectable by tapping the conversion instruction key, and a second conversion instruction key different from the conversion instruction key is pressed, If the end of the candidate selection target is an independent word, input one of a character string or a group of character strings registered in advance at a position immediately after the independent word, and A sentence input method characterized by inputting one of the pre-registered character strings or character string groups by substituting the attached word at the end of the part where the character string is an attached word.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction and operation of the first and second inventions will be described with reference to the drawings. FIG. 1 is a diagram showing an operation example of a text input method of a technique related to the present invention . In FIG.
(A) shows a state in which the sentence "member is the chairman" is already displayed, and (b) to (g) shows a character string "selection" input by a conventional kana-kanji conversion operation. The process is shown.

The operation of the technology related to the present invention is as follows:
It is shown in (i). In (g), all the entered character strings “member is chairman” are in a confirmed state. In the conventional kana-kanji conversion, it is ignored that it is meaningless to hit the conversion instruction key in the state of (g). However, in the present invention, when the conversion instruction key is pressed as in (h), a character string group is displayed at the position of the cursor (represented by ■ in the figure) as shown in (i). This character string group is registered in advance. In the example of FIG. 1, a character string corresponding to a particle as a character string group
"Ha", "Ni" and "kara" are registered. The selection from the character string group can be performed by the conversion instruction key and the confirmation instruction key in the same manner as the kana-kanji conversion operation ((j) to (k)).
Operation of).

FIG. 2 is a diagram showing an operation example of the text input method of the first invention. In FIG. 2, (a) shows a state in which the sentence “member” is already displayed,
(B) to (e) show a process in which a character string mixed with kanji and kana is input by a conventional kana-kanji conversion operation. At the stage (e), the kana character string “Kaichiyo Taku” is converted to a character string mixed with kanji or kana “Chairman selection”, and the “Chairman” part is subjected to candidate selection.

The operation of the first invention is shown in (e) to (g). At the stage of (e), when the normal Kana-Kanji conversion instruction key is pressed, a homonym such as “Konsei” is displayed for “Chairman” as a candidate for candidate selection. In the operation of one invention, a second conversion instruction key different from the conversion instruction key is pressed (operation (f)). Then, a group of character strings registered in advance similar to the case of the technology related to the present invention is displayed, and it becomes possible to select and input from among them (state (g)). In the case of the first invention, the position at which the character string group is displayed is immediately after the candidate selection target (in this example, immediately after “Chairman”).

FIG. 3 is a diagram showing an operation example of the text input method according to the second invention. In FIG. 3, (a) shows a state in which the sentence “member” is already displayed,
(B) to (e) show a process in which a character string mixed with kanji and kana is input by a conventional kana-kanji conversion operation. At the stage (e), the kana character string “Kaichi no Sentaiku” is converted to a character string mixed with kanji or kana “Chairman's selection”, and the “Chairman's” part is selected for candidate selection. I have.

The operation of the second invention is shown in (e) to (g). At the stage of (e), when the conversion instruction key of the normal kana-kanji conversion is pressed, a homonym such as "smooth" is displayed for "chairman's" which is a candidate for selection. In the operation of the second invention, the user inputs a second conversion instruction key different from the conversion instruction key ((f)).
Operation of). Then, a pre-registered character string group similar to that of the technology related to the present invention and the first invention is displayed,
It becomes possible to select and input from among them. In the case of the second invention, if the end of the candidate selection target is at the end of an adjunct, the character string group is displayed in a form that replaces the adjunct ((g)). . On the other hand, if the end of the candidate selection target is an independent word, the character string group is displayed immediately after the candidate selection target position.

In the first invention and the second invention, when the second conversion instruction key is depressed and the end of the candidate selection target is an independent word, the appearance is changed. It is exactly the same (both are as shown in FIG. 2). On the other hand, when the second conversion instruction key is pressed, if the end of the candidate selection target ends with an adjunct,
The first invention and the second invention have different appearances. For example, in the second invention, when the position of "President" is a candidate for candidate selection, when the second conversion instruction key is pressed, as shown in FIG. The part is replaced with a group of character strings registered in advance and displayed as "Chairman", "Chairman", "Chairman", "To Chairman", "From Chairman", and the like. On the other hand, in the first invention, when the second conversion instruction key is pressed when the part "Chairman" is a candidate for selection, a character string group registered in advance immediately after "Chairman" is inserted. It is displayed as "President's message", "President's message", "President's message", "President's message", "President's message", and so on.

In the operation examples using FIGS. 1 to 3 described above, the kana-kanji conversion is performed using the kana character string. However, the same applies to the case of a roman character string. Also, the description has been given using a group of character strings corresponding to particles as a group of character strings registered in advance. However, in the present invention, the group of character strings to be registered is not limited. May be registered, or ",""."
May be registered. In FIGS. 1 to 3, the character string groups are displayed at once, but may be displayed one by one in order.
