Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document processing device that can automatically and collectively correct errors in combinations of lowercase and uppercase letters in words in a created document.

[Prior Art] Generally, a document processing device is also called a word processor.
After creating a document by entering text information from the keyboard,
It is known as a device that can perform editing processes such as inserting, converting, and deleting characters in a created document.

When using such a document processing device to create a document containing uppercase and lowercase characters, for example, Roman characters,
There was a problem in that the key operations involved in inputting uppercase and lowercase letters were complicated for the operator.

This point will be explained in detail.

On the keyboard of a document processing device, a combination of alphabetic character keys and a shift key is used to input uppercase letters and lowercase letters.

For example, when inputting the lowercase letter "a", the operator presses the letter key labeled "A". Further, when inputting the capital letter "A", the operator simultaneously presses the letter key displaying "A" and the shift key for instructing switching between lowercase and uppercase letters.

For example, according to German grammar rules, the following characters must be converted from lowercase to uppercase:

(i) The first character of a sentence (if) The first character of a noun in a sentence [Problem to be solved by the invention] Therefore, the operator must press two keys at the same time every time he inputs a capital letter. The key operations become complicated, and erroneous key operations may result in erroneous inputs such as not inputting the desired capital letter or inputting the wrong character. As a result, conventional document processing apparatuses have had the problem of requiring the operator to correct upper and lower case letters successively by key operation.

Therefore, the purpose of the present invention is to solve such problems,
An object of the present invention is to provide a document processing device that can reduce pressure on a key operator regarding input of lowercase and uppercase letters.

[Means for Solving the Problems] In order to achieve such an object, the present invention provides a storage means for storing document information created by a document information input means, and a storage means for storing document information created by a document information input means. word reading means for sequentially reading word by word based on word delimiter information in the document information, and a combination of uppercase and lowercase letters in the word read by the word reading means from the storage means matches a predetermined grammatical rule. a determination means for determining whether or not the determination is made, and a combination of uppercase and lowercase letters of the word in the storage means corresponding to the word read by the word reading means when the result of the determination by the determination means is a negative determination is determined in advance; The present invention is characterized by comprising a correction means for correcting it so as to match the grammatical rules set.

[Function] In the present invention, the word reading means sequentially reads out words from the created document stored in the storage means, and the determining means determines whether or not the read words match a predetermined grammar rule. judge. Depending on the result of the determination by the determining means, the modifying means modifies the combination of characters of the word in the storage means corresponding to the characters of the read word according to predetermined grammar rules.

As a result, the operator need only create a document consisting of lowercase letters, for example, and the lowercase and uppercase letters will be corrected according to the grammatical rules, eliminating the need for inputting instructions for lowercase and uppercase letters.

[Example] Embodiments of the present invention will be described in detail below with reference to the drawings.

The word information stored in the dictionary storage section 3b is used for the next process.

(1) Spell check of words in created sentences (2)
Determining the part of speech of a word in a created sentence Below, a procedure for checking the spelling of a word and correcting uppercase and lowercase letters in this embodiment will be explained.

Character information input sequentially from the keyboard 1 by the operator is stored in the created text storage unit 4a via the MPU 2, and the text stored in the created text storage unit 4a is displayed on the display device 5 as shown in the fourth figure. Assume that it is displayed. In addition, the created sentences are German sentences, and the grammar rules that require the first letter of the created words to be capitalized are a) when the word is a noun, b) when the word is located at the beginning of a sentence, and when the word is a noun. do.

FIG. 5 shows the main configuration of the control procedure executed by the MPIJ2 shown in the second diagram.

In FIG. 5, step 5100 is the created text storage unit 4.
The process of extracting character string information in units of words from the text information stored in a is shown. This control procedure corresponds to the word reading means 200.

Step 5200 shows a process of determining whether the extracted word is at the beginning of the sentence and correcting the first letter of the word at the beginning of the sentence to an uppercase letter.

Step 5300 shows a process of determining whether or not a capital letter exists in the extracted word, and converting the characters in the word except the first character into tJz characters.

Step 5400 indicates processing for determining whether the extracted word is a noun and correcting the first letter of the noun word to an uppercase letter.

The control procedure of steps 5200 to 5400 is
0 and the correction means 400.

In step 5500, the extracted words are stored in the created sentence storage unit 4.
The process of determining whether the word stored in a is the last word of the sentence is shown.

Based on such a procedure, spell checking for uppercase letters is performed sequentially from the first word of the created sentence to the last word.

FIG. 6 shows a specific control procedure regarding the word extraction process in step 5100 shown in FIG.

Since this control procedure is a well-known control procedure, a brief explanation will be provided.

The MPU 2 reads out the first character "d" (see FIG. 4) in the created text storage section 4a. Next, it is determined whether the read character "d" is a character indicating a word break (step 5107). Space characters and the like are known as characters that indicate word breaks.

Next, the read character is added to the word register in MPII2. At this stage, the content of the word register becomes "d" (step 5108).

Next, the MPt 12 updates the read address and reads the next character from the created text storage section 4a. (Step 51
02). Following the above steps (steps 5102→5103)
→5106, 5107, 5108, 5102) is repeated, and when the stored content of the word register becomes "diE", the next blank character is detected in step 5107, and the word "diE" is extracted into the word register.

Next, a procedure for detecting words at the beginning and end of a sentence in this control procedure will be described.

In this example, the period character “°” indicates the end of a sentence.
,” is detected, and the next first word excluding the blank character is used as the first word of the sentence.For this, the period character “,”
Set the end-of-sentence flag when a word with is detected. The end of sentence flag is a register that stores information indicating that the word stored in the word register is the end of a sentence.

In this example, the MPII 2 also includes an end-of-sentence flag and a beginning-of-sentence flag for storing information indicating that the word stored in the word register is at the beginning of the sentence.

For example, the word (W-10) at the end of the sentence shown in Figure 4 “Li5c
h” is stored in the word register, then the period character “
,” are read by the MPU 2 (step 510
2. Note: At this point, the end-of-sentence flag is 0''), step 51G
The procedure progresses to 2-5103-5106-5107, and MP
U2 sets the end of sentence flag to "1". Spell check of the word information “tisch” stored in the word register (
(described later), the next blank character is read.

(Steps 5101-45102).

The read character is a blank character, and step 5103
Since the end-of-sentence flag is set to "1" during control, the procedure proceeds to steps 5102-5103-5104-5102 and the next character "A" (see FIG. 4) is read out.

Since the end of sentence flag remains "1" and the read character is not a blank character, the MPU 2 determines that the read character is the first character of the sentence and sets the end of sentence flag to "0". , "B" indicating that the word stored in the word register is the first word of the sentence is set as the beginning of sentence flag.The steps related to the word extraction described above are executed,
The first word is read out by MPt12.

In this example, the character used to detect the end of a sentence is a period “
, ', but there are also exclamation marks "bi" and question marks?
” etc. are known as characters to detect the end of a sentence, so
The same processing as when detecting a period character may be performed when these characters are detected.

FIG. 7 shows a control procedure for changing the first letter of a sentence to an uppercase letter in step 5200 shown in FIG.

In FIG. 7, the MPU 2 determines whether or not the beginning of sentence flag is 1°°, and when the beginning of sentence flag is "1", it identifies that the word stored in the word register is the word at the beginning of the sentence. . (Step 5201).

For the word at the beginning of a sentence, the first character of the word register and the corresponding character in the created sentence storage section 4a are rewritten to uppercase letters by the MPt12.

Furthermore, the MPII 2 sets a sentence beginning flag to "0" in the word register to control that the next word to be stored is a word in a sentence. When the sentence head flag is "0", this control procedure is ended and the control procedure proceeds to step 5300.

FIG. 8 shows the control procedure for checking the spelling of words in step 5300 shown in FIG.

In FIG. 8, the MPU 2 sequentially reads out the characters stored in the word register and determines whether all the read characters are capital letters.

If all the characters stored in the word register are uppercase letters, it is determined that the input sentence is input using uppercase letters.
The water control procedure is ended without performing a smooth check on the noun described later, and the process returns to step 5100 in FIG.

If all the characters stored in the word register are not uppercase, the MPU 2 checks whether the second and subsequent characters in the register are all lowercase (step 5).
302).

When the second and subsequent characters include uppercase letters, the uppercase letters in the word register are changed to the corresponding lowercase letters, and the characters corresponding to the uppercase letters stored in the created sentence storage unit 4a are also changed to uppercase letters. change. (Step 5303
).

FIG. 9 shows the noun spell check control procedure in step 5400 in FIG.

In FIG. 9, the MPU 2 investigates whether the word stored in the word register is in a noun group in the dictionary storage section 3b. When the word in the word register is found to be a noun through this investigation, the MPU 2 checks whether the first letter in the word register is an uppercase letter or not. Change the lowercase letters in the storage section 4a to uppercase letters (step 54)
03).

Furthermore, when the word in the word register is not in the noun group in the dictionary storage section 3b, the MPU 2 checks whether the first letter is an uppercase letter or a lowercase letter, and if the word is a noun and the first letter is a lowercase letter, (Step 5)
411→5412).

Note that, as described above, when a word is at the beginning of a sentence, it has already been converted to uppercase letters, so even if this word is not a noun, it is not changed to lowercase letters.

In this example, an example in which the first letter of a noun is converted to uppercase like in German has been explained, but in the case of English, the first letter of a proper noun is capitalized.

Therefore, when the present invention is applied to a document processing device for English, words of proper nouns may be stored together in the dictionary storage section 3b.

In addition, as stipulated in JIS, character codes are generally grouped into uppercase alphabets and lowercase alphabets, so for example,
If the character code to be spell-checked is within the code range of the upper case group, it can be determined that it is an upper case letter.

Further, words other than nouns are stored in the dictionary storage unit 3b, and the dictionary storage unit 3b stores words other than nouns, and performs the process of determining whether or not the words in the created sentence in the ninth diagram of this embodiment exist in the dictionary storage unit 3b. It is also possible to display a word that is not in the storage section 3b as being incorrectly spelled.

[Effects of the Invention] As explained above, according to the present invention, words are sequentially read out from a prepared document stored in a storage means by a single reading means, and the read words conform to predetermined grammatical rules. A determining means determines whether or not they match.

Depending on the result of the determination by the determining means, the modifying means modifies the combination of characters of the word in the storage means corresponding to the characters of the read word according to predetermined grammar rules.

As a result, the operator only needs to create a document consisting of lowercase letters, for example, and the lowercase and uppercase letters are corrected according to the grammatical rules, so there is no need to input instructions for lowercase and uppercase letters.
