2. Description of the Related Art FIG. 2 is a block diagram showing the configuration of a first conventional text input device. In FIG. 2, input means 1
inputs a kana character string, instructs to convert the kana character string to a character string containing kanji and kana, and specifies the insertion position of the character string containing kanji and kana. The input means 1 is realized by a keyboard or the like. The word dictionary storage means 2 stores a word dictionary used in kana-kanji conversion. The word dictionary storage means 2 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 into a kanji-kana mixed character string by referring to a word dictionary according to the kana character string input from the input means 1, conversion instructions, insertion position specification, etc. do. The text storage means 4 stores the kanji-kana mixed character string obtained by the kana-kanji conversion means 3. The text storage means 4 is realized by an IC memory, a magnetic disk device, or the like. The text display means 6 displays the kanji/kana mixed character string stored in the text storage means 4. The text display means 6 is realized by a CRT display, a liquid crystal display, or the like. The control means 7 controls each means by giving instructions on the timing of operations and instructions on the execution position of the operations. The kana-kanji conversion means 3 and the control means 7 are integrated and realized by a CPU (computer software). This first conventional text input device is, for example, a kana-kanji conversion means disclosed in JP-A-53-107986 ``Kana-Kanji Conversion Method'' and JP-A-55-43634 ``Kana-Kanji Conversion Device''. This was realized using . In this first text input device, the kanji-kana mixed character string obtained by the kana-kanji conversion means 3 is only written into the text storage means 4;
does not refer to the sentences stored in the sentence storage means 4.

FIG. 3 is a block diagram showing the configuration of a second conventional text input device. In the conventional second text input device, the input means 1 that also existed in the conventional first text input device
In addition to the word dictionary storage means 2, the kana-kanji conversion means 3, the text storage means 4, the display means 6, and the control means 7, a pronunciation storage means 8 is added as a component. The pronunciation storage means 8 stores the kana character string input by the input means 1 via the kana-kanji conversion means 3. The reading storage means 8 is realized by an IC memory, a magnetic disk device, or the like. In the conventional second text input device, the kana-kanji conversion means 3 not only writes the converted character string containing kanji and kana into the text storage means 4, but also writes the pronunciation corresponding to the text storage means 4 into the pronunciation storage means 8. . Further, the kana character string corresponding to the range specified by the input means 1 is read out from the pronunciation storage means 8 and becomes the object of the kana-kanji conversion means 3 again. The conventional second text input device makes it possible to convert a part that has already been converted into kanji into another kanji without having to input the kana character string again. This is to realize the "reconversion function". Conventional second text input devices are described, for example, in JP-A-59-165124 "Japanese Word Processor" and JP-A-62-290966 "Sentence Editing Device." Since this second text input device is intended for a "reconversion function," in principle, the contents of the refreshment storage means 8 are only used again as input, and the contents outside the reconversion target range are not referred to.

[Problem to be Solved by the Invention] In kana-kanji conversion, when determining the kanji corresponding to a certain kana character string, accuracy is improved by also referring to the analysis information before and after the kanji. For example, in the kana string ``Kotori wo Nasu'', if we consider only the ``talk'' part, we can say ``talk'' and ``talk''.
There are multiple possibilities such as "let go" and "let go." but,
If we also consider the kana character string ``Kotori wo'' immediately before ``Hanasu'', we can determine ``Release the bird''. However, it is possible to determine conversion candidates by considering the preceding and following situations as described above, when the entire character string of "Kotori wo Nasu" is written at once,
Alternatively, only when it is continuously given to the kana-kanji conversion means 3. For example, if you enter and confirm the sentence ``I keep a small bird'' (and save it in a text file), then delete the part of ``I keep a bird'' and re-enter the word ``Talk,'' ” cannot be referenced immediately before “Kotori wo”. In other words, it is no longer possible to decide whether to ``speak'', ``let go'', or ``let go'' for ``talk''. Referring to the analysis information of the part that has already been confirmed and saved can be used to analyze a wider range of sentences (context).
This is even more strongly desired when attempting to perform advanced analysis processing that takes into consideration the following.

[0005] An object of the present invention is to provide a text input device that can also refer to analysis information of a part that has already been finalized and saved, and can perform kana-kanji conversion using a context processing framework.

[0006]

[Means for Solving the Problems] The text input device of the present invention inputs a kana character string, instructs to convert the kana character string to a character string containing kanji and kana, and specifies the insertion position of the character string containing kanji and kana. a storage means for storing a word dictionary; a kana-kanji converting means for converting the kana character string into a kanji-kana mixed character string by referring to the word dictionary according to the input means; and a kanji-kana mixed character string according to the input means; comprising a text storage means for storing a character string, a storage means for storing analysis information of the kana-kanji conversion means corresponding to a character string containing kanji and kana in the text storage means, and a display means for displaying the character string containing kanji and kana; The kana-kanji conversion means refers to the analysis information corresponding to the kanji-kana mixed character string and the word dictionary when a corrected kana character string for the kanji-kana mixed character string stored in the text storage means is input. It is characterized by converting a corrected kana character string into a character string containing kanji and kana.

Embodiments Below, embodiments of the text input device of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an embodiment of a text input device of the present invention. In FIG. 1, an input means 1, a word dictionary storage means 2, a kana-kanji conversion means 3, a text storage means 4, a display means 6, and a control means 7 are the same components as the conventional text input device already described. A newly added component is analysis information storage means 5. The analysis information storage means 5 is shown in FIG.
Like the reading storage means 8, it is realized by an IC memory or a magnetic disk device, but it is not only possible to store not only the kana character string corresponding to the kanji-kana mixed character string stored in the sentence storage means 4, but also the boundaries between words and each character string. It also remembers information such as the part of speech and meaning of words. The analysis information is written from the kana-kanji conversion means 3.

The kana-kanji conversion means 3 analyzes the kana character string to be converted. In addition, in order to select a plurality of conversion candidates, the kana-kanji conversion means 3 also refers to the analysis information regarding the character string of the part whose kanji-kana mixed notation has already been determined and is stored in the analysis information storage means 5. Perform kana-kanji conversion.

For example, the operation will be described in the case where, immediately after rereading a sentence from a file, an attempt is made to input a kana character string such as ``hanasu'' immediately after the already determined character string ``kotoriwo''. First, the kana-kanji conversion means 3 inputs the input means 1
Receives the kana character string ``hanasu'' from , and internally converts it to ``
Form candidates such as "speak,""release," and "let go." At this time, the word dictionary shows that each verb has an object case of [abstract/fact] (to speak), [object] (to release), and [animal] (to release). Furthermore, "little bird (noun, animal)/wo (case particle, objective case)" is obtained from the analysis information storage means 5 as analysis information for the immediately preceding character string. A candidate that fits well with this is “
"Release" is determined as the final conversion result.
