Description

The present invention relates to a character processing device for processing a document, and more particularly to a character processing device having a function of pointing out a character string satisfying a specific level in a document. Is.

[Prior Art] Conventionally, as a character processing device which points out a character string satisfying a specific level in a document, for example, a difficult character string, the difficulty level of the character string is set in advance in two stages of difficulty and easiness. Every
There was a character processing device that had the function of pointing out only difficult character strings.

For example, there is a character processing device that divides the kanji into two, that is, the common kanji and the kanji other than the common kanji, and points out only the common kanji.

[Problems to be Solved by the Invention] However, in the above-described conventional character processing device, the difficulty level is divided into two stages and only the difficult character string is pointed out. There was a drawback that you could not specify a difficulty level and point out a character string that was more difficult than that.

For example, when an elementary school teacher creates a document for students of various students and wants to avoid using Kanji that has not been taught yet for each grade, I couldn't create a legible document.

In learning kanji, not all the readings of a certain kanji are learned at once, but the time of learning is often different depending on the reading. Therefore, there is a problem that even if a kanji that has already been learned for a certain reading is used in a way that has not been learned yet, the student cannot read it.

[Means and Actions for Solving the Problems] An object of the present invention is to eliminate the drawbacks of the above-mentioned conventional example.

According to the present invention, in the character processing device, a document storage means for storing a document, a difficulty level storage means for storing a level of difficulty for each reading of a Chinese character, and a difficulty level to be pointed out. Designating means for designating a level and a document stored in the document storing means are analyzed using a dictionary, and kanji having the same level of reading as the level of the difficulty level designated by the designating means from the document, Alternatively, a search means for searching for kanji having a reading level equal to or higher than the designated difficulty level, and a kanji searched by the search means,
Based on the difficulty level stored for each reading of Kanji, the display control means for pointing out in the document is provided.
The Kanji corresponding to the reading of the corresponding difficulty level is pointed out in the document.

The indication information stores information about the learning level (Kanji level) of the indicated Kanji itself, information about the reading learning level (reading level), and information about the learning flag. The meanings of the kanji level and reading level are (4)
Is shown in. The learning flag is information indicating the learning state of the indicated kanji. If the value is 1, it means that the kanji has been learned, and if it is 0, it means the kanji has not been learned yet. Means

FIG. 5 is a diagram showing the configuration of the Kanji learning level dictionary KLDIC3c.

As shown in (1), Kanji learning level dictionary KLDIC3
c is divided into a kanji level part and a reading information part. In the kanji level part, the level information of each kanji (kanji level information) and the pointer to the reading information are fixed length of 1 byte and 4 bytes, respectively. Are stored in the same order as the character codes. Therefore, from the value of the character code, it is possible to obtain the kanji level information and the pointer to the reading information for the character. Also, by tracing the pointer to the reading information, the reading information of the Chinese character can be obtained. A plurality of reading candidates for the Chinese character can be stored in the reading information, and reading and reading level information (reading level information) are stored in the reading candidate.
The reading is stored in JIS code of 1 character and 2 bytes.
Since B is all off and the MSB of the level information is on, it is possible to determine the boundary between the reading candidates.

(2) shows the structure of Kanji (reading) level information. The kanji (reading) level information stores a kanji (reading) level and a learning flag. The kanji level information stores the level of the kanji itself, and the reading level information stores the reading level. The meaning of the level value is exactly the same as in FIG. 4 (4). Kanji (reading) level settings shall be given by another means. The learning flag is information indicating the learning state of the indicated kanji (reading). If the learning flag is 1, it means that the kanji has been learned (reading), and if it is 0, the kanji that has not been learned yet ( Read). If even one learning flag of the reading level information in the reading information for one kanji is 1, the learning flag of the kanji level information is always 1, and only when all the learning flags of the reading level information are 0. The learning flag of the kanji level information is 0. Figure 6 shows TBUF3a to point out a particular level of Kanji.
