DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a text input device, such as a word processor, capable of inputting Japanese text by a kana-kanji conversion means, displaying the input text, and storing the text. is there.

[0002]

2. Description of the Related Art FIG. 2 is a block diagram showing a first example of a conventional text input device.

In FIG. 2, an input means 1 inputs a kana character string, instructs conversion of the kana character string into a kanji / kana mixed character string, and designates an insertion position of the kanji / kana mixed character string. , A keyboard, etc.
The word dictionary storage means 2 stores a word dictionary used for kana-kanji conversion, and is realized by an IC memory, a magnetic disk device, or the like. The kana-kanji conversion means 3 converts the input kana character string to a kanji-kana mixed character string by referring to a word dictionary in accordance with a kana character string input from the input means 1, a conversion instruction, an insertion position designation, and the like. . The sentence storage means 4 stores the character string mixed with the kanji and kana obtained by the kana-kanji conversion means 3 and is realized by an IC memory, a magnetic disk device, or the like. The display means 6 displays a character string mixed with kanji or kana stored in the sentence storage means 4.
This is realized by an RT display, a liquid crystal display, or the like. The control means 7 controls each means such as giving an instruction of an operation timing and an instruction of an execution position of the operation. The kana-kanji conversion means 3 and the control means 7 are integrated,
(Computer software).

A text input device as shown in FIG. 2 is disclosed in, for example, Japanese Patent Application Laid-Open No. Sho 53-107986, "Kana-Kanji Conversion System" and Japanese Patent Application Laid-Open No. 55-43634, "Kana-Kanji Conversion Device" This is realized by using kanji conversion means.

In the first conventional example, the character string mixed with the kanji and kana obtained by the kana-kanji conversion means 3 is simply written into the text storage means 4, and the kana-kanji conversion means 3 converts the text stored in the text storage means 4. No reference.

FIG. 3 is a block diagram showing a second example of a conventional text input device. In FIG. 3, in addition to the input unit 1, the word dictionary storage unit 2, the kana-kanji conversion unit 3, the sentence storage unit 4, the display unit 6, and the control unit 7, which are also present in FIG. Have been. The reading means 8 stores the kana character string input by the input means 1 via the kana-kanji conversion means 3.
This is realized by an IC memory, a magnetic disk device, or the like.

In FIG. 3, the kana-kanji conversion means 3 not only writes the converted kanji-kana mixed character string into the sentence storage means 4 but also writes the sentence storage means 4 into the reading storage means 8.
Write the corresponding yoganana. Further, a kana character string corresponding to the range specified by the input means 1 is read out from the yomigana storage means 8 and is again subjected to the kana-kanji conversion means 3.

[0008] This second conventional example allows a part once converted to a kanji and determined to be converted to another kanji without re-inputting a kana character string. This is for realizing the "reconversion function".

The apparatus of the second conventional example is described in, for example, JP-A-59-165124, "Japanese Word Processor" and JP-A-62-290966, "Sentence Editing Apparatus". Since the second conventional example is intended for the "reconversion function", in principle, only the contents of the good-looking storage means 8 are used again as input, and the contents of parts other than the reconversion target range are referred to. Not done.
In addition, since a character string mixed with kanji and kanji can be associated only with a conversion unit, information is lost at a portion where deletion or correction is performed in a character unit.

[0010]

In the kana-kanji conversion, the accuracy of a kanji corresponding to a certain kana character string is increased by referring to analysis information before and after the kanji.

For example, regarding the character string "Kanazawa", if only the part "Hanasu" is considered,
There are multiple possibilities, such as "speak", "release", "release". However, considering the kana character string "Kotori" immediately before "Hanasu", it can be determined that "Release the bird".
However, the conversion candidates can be determined in consideration of the above and below as described above only when the entire character string of “Kotori hanasu” is given to the kana-kanji conversion means 3 at once or continuously. . For example, if you enter the text "Keep a bird" once and confirm it (and save it in a text file), then delete the "Keep" part and enter "Hanasu" again, Cannot be referred to immediately before "". That is, it becomes impossible to determine any of "talk", "release", "release", and the like for "talk".

Reference to the analysis information of a part which has already been determined and saved is more strongly demanded when performing advanced analysis processing in consideration of a wider range of text (context). However, the above-mentioned prior art cannot satisfy this demand.

An object of the present invention is to provide a sentence input device which enables Kana-Kanji conversion with a framework of context processing, also referring to analysis information of an already determined and saved portion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to FIG. FIG. 1 is a block diagram showing one embodiment of the text input device of the present invention. In FIG. 1, an input unit 1, a word dictionary storage unit 2, a kana-kanji conversion unit 3, a sentence storage unit 4, a display unit 6, and a control unit 7 are components similar to those of the conventional sentence input device described above. In this embodiment, newly added components include a text analysis unit 9 and an analysis information buffer 5.
And

The sentence analysis means 9 analyzes a part of the sentence stored in the sentence storage means 4 with reference to the word dictionary stored in the word dictionary storage means 2, and writes the result in the analysis information buffer 5. The sentence analysis means 9 itself is a known means, for example, "Storage of Japanese language dictionary and automatic division of Japanese sentence" (Nagao et al., "Information Processing", Vol. 19, No. 6,
No. 1978). A part of the sentence targeted by the sentence analyzing means 9 is designated by the control means 7, but is a part before and after the position where the sentence is to be inserted by the kana-kanji conversion means 3.

The analysis information buffer 5 is a means for temporarily storing the analysis result of the text analysis means 9 and can be realized by an IC memory or the like. The information stored is the result of word segmentation for the target part, and the notation, reading, and
Parts of speech and meaning.

The kana-kanji conversion means 3 can not only analyze the kana character string to be converted, but also select a plurality of conversion candidates with reference to the analysis information buffer 5. At this time, the analysis information buffer 5 stores the results of analysis by the sentence analysis means 9 regarding the texts before and after the position where the text is to be inserted by the kana-kanji conversion means 3, and the kana-kanji conversion means 3 Context information will be available for selection.

For example, a description will be given of an operation in a case where an attempt is made to input a kana character string "Hanasu" immediately after the already determined character string "Small bird" immediately after rereading a sentence from a file. First, when a sentence is to be inserted immediately after "the little bird", the sentence analyzing means 9 is activated,
The text before and after that is analyzed. In this example, since there is no text behind, the part of “the little bird” ahead is analyzed. As a result, the analysis information buffer 5 stores "small bird (bird, noun, animal) /" (case particle, object case) as the analysis result of the immediately preceding character string. Next, the kana-kanji conversion means 3 receives the kana character string "Hanasu" from the input means 1, and internally forms candidates such as "speak", "release", "release". At this time, from the word dictionary, it is understood that each verb takes as an object case [abstract / fact] (speaks), [object] (releases), and [animal] (releases). At this time, referring to the analysis information buffer 5, there is "small bird (kotori, noun, animal) / (case particle, object case)", and since it is a candidate that matches well, "release" is finally Is determined as a proper conversion result.

[0020]

As described above, according to the present invention, it is possible to perform kana-kanji conversion with reference to the analysis information of a part which has already been determined and saved in a file. With this framework, it is also possible to introduce advanced context processing into kana-kanji conversion processing.
