Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a Roman word processor, and more particularly to a correction means for correcting erroneously input English words.

Prior Art Conventionally, in a Roman word processor, English text input using a keyboard is displayed on a display unit such as a CRT. If an incorrect English word is entered, the central processing unit determines that there is no matching word data stored in the dictionary memory in advance, and displays the word on the CRT. is now displayed blinking.

However, when correcting such incorrect English words, if you did not know the correct spelling, you had to look it up in a dictionary or other means.

Purpose The purpose of the present invention is to eliminate the drawbacks of conventional word processors as described above, and to quickly extract correct English words that are similar to incorrectly input English words from the dictionary memory 7 and display them on the display. To provide a Roman word processor that can easily and quickly correct English words by displaying them and selecting desired words from among them.

Structure of the Invention In order to achieve the above object, the structure of the present invention includes an input device for inputting English words, etc., and a display for displaying the corresponding English words, etc. on a display unit based on an output signal of the input device. a dictionary memory storing a plurality of word data, and a determining means for determining whether an input English word exists in the dictionary memory and displaying the result on a display section. , at least two consecutive characters in the character string of each word data stored in the dictionary memory
A frequency memory that stores a character string and the number of occurrences of that character string as a pair, and an English word that is spelled similar to an English word that does not exist in the dictionary memory from among input English words. a search and extraction means for searching and extracting words from a dictionary memory and a frequency memory; a calling means for displaying words extracted by the search and extraction means on a display; and a desired word from among the displayed correct English words. It is equipped with a selection means for

Embodiment An embodiment embodying the present invention will be described below with reference to the drawings.A Roman word processor 1 is provided with a large number of character keys 3 and a space key 4 as an input device on an input board 2. . and,
When the character keys 3 are operated, corresponding character data, ie, various character data such as alphanumeric characters and numbers, are selected and input.

A correction key 5 is provided on the right side of the character keys, and is used when correcting an incorrectly input English word using the character keys 3. Below the correction key 5 are a next candidate call key 6 (hereinafter referred to as a call key) as a call means and a cursor movement key 7 as a selection means.
A selection execution key 8 is provided. The call key 6 is used when you want to display an English word with one or two letters different as the next candidate for a misspelled English word input with the character key 3, and move the cursor. Key 7 and selection execution key 8 are used to replace a desired English word with an incorrect English word from among the next candidates. A CRT 9 as a display means is provided behind the input board 2, and is configured to display English words and numbers entered using the character keys 3, or the next candidate entered using the call key 6. A printer device 10 is provided on the side of the CRT 9, and is capable of printing English text input using the character keys 3 onto printing paper.

Next, the electronic circuit built into the Latin word processor 1 as described above will be explained with reference to FIG.

Character data based on each key operation is displayed by the display function,
It is output to a central processing unit (hereinafter referred to as CPU) 11 which has various functions such as a discrimination function and a search and extraction function,
Based on these signals, the CPU 11 displays characters on the CRT 9.

A dictionary memory 12 connected to the CPU 11 is a read-only memory (ROM) in which a large number of English words are stored as word data. Similarly
A frequency memory 13 connected to the CPU 11 is a read-only memory (ROM), and a dictionary memory 1
Among all the character strings of 15,000 words arbitrarily extracted from the word data stored in 2, consecutive two character strings and the number of occurrences of the character strings are stored in pairs. In other words, as shown in part in Figure 3, for example, for "ao", "7", "bo"
It is stored as ``229'' for ``qo'' or ``0'' for ``qo''. A working memory 14 consisting of readable and rewritable memory (RAM) is also connected to the CPU 11, and the character key 3
Character data from CPU 11 and input from
Word data extracted from the dictionary memory 12 by the CPU 11 is stored.

Then, the CPU 11 determines whether or not the English word entered using the character key 3 and the space key 4 exists in the dictionary memory 12. If it does not exist, the English word is displayed blinking on the CRT 9, and When the call key 6 is pressed in this state, the CPU 11 selects an English word that has the same number of characters as the English word but has one or two different spellings.
English words with different letters are searched and extracted from the dictionary memory 12 and the frequency memory 13 and displayed on the CRT 9.

Next, the operation of the Latin word processor 1 constructed as described above will be explained with reference to FIG.

Now, in a state where the CPU 11 is performing various operations on the input board 2, when alphanumeric characters or alphanumeric characters are input using the character keys 3, the CPU 11 sequentially displays the characters on the CRT 9, and also displays the characters corresponding to the characters. Store the data in working memory 14. In this way, after inputting a desired English word using the character keys 3, when the space key 4 is pressed to set a predetermined interval between the following words, the CPU 11 inputs the English character string up to that point. It is recognized as one English word, and that English word is stored in dictionary memory 1.
Search to see if it exists in 2. Then, the English word is entered with the correct spelling and the dictionary memory 1 is entered.
If it is found to exist within 2, the CRT
will be displayed as is. Also, for example, "consider"
The word that should have been entered as "consyder" was incorrectly entered as "consyder".
When inputted, the CPU 11 determines that the word does not exist in the dictionary memory 12 and displays the word in a flashing manner.

For the blinking English word, press cursor movement key 7,
The spelling can be corrected by operating the correction key 5 and character key 3, but if the correct spelling of "consyder" cannot be remembered, the call key 6 is pressed. Then, the CPU 11 searches and extracts words having the same number of characters but one character different from "consyder" from the dictionary memory 12 and the frequency memory 13 as the next candidates, and sequentially displays them in the lower part of the CRT 9.

That is, the CPU 11 first replaces the initial letter c of "consyder" with a, and stores the number of occurrences of the replaced character, the subsequent "o", and the character string "ao" in the frequency memory 1.
Read from 3. Currently, the number of occurrences of the "ao" string is 7
Therefore, the CPU 11 searches the dictionary memory 12 for an English word spelled as "aonsyder", and when it determines that it does not exist, performs the same process for the word with the initial letter replaced with "b".

In this way, processing is performed by sequentially replacing the initial letters in alphabetical order, and eventually the initial letters are replaced with q.
, the number of occurrences for the character string "qo" in the frequency memory 13 is 0, so the CPU 11
omits the search for "qonsyder" from the dictionary memory 12 and moves on to the next operation for the initial letter r.

As described above, the CPU 11 sequentially replaces each spelling of "consyder" from a to z, reads from the frequency memory 13 the number of occurrences of the character string of the replaced character and the character that precedes or follows it, and calculates the number of occurrences. is other than 0, it is searched to see if the replaced word exists in the dictionary memory 12, and if it exists, the word and the number of occurrences of the character string in the word are sequentially stored in the working memory 14. .

Through this operation, all the corresponding words are stored as next candidates in the working memory 14, and then the words stored in the working memory 14 are sequentially stored in the CRT 9 in descending order of the number of occurrences of character strings within the word.
to be displayed. At this time, if the number of applicable words is too large to be displayed in a predetermined position on the CRT 9, by pressing the call key 6 again, the remaining next candidates are sequentially read out from the working memory 14 and displayed.

When you find "consider", which is the correct spelling for "consyder", from among the next candidates, use the cursor movement key 7 to move the cursor under the first letter of that word, and then press the selection execution key 8.
The CPU 11 displays the word in place of the flashing "consyder" and waits for the next key operation.

If you cannot find the correct spelling of the word that is spelled incorrectly from among the next candidates with a one-letter difference as described above for the blinking word, press the call key 6 again, and the blinking word will appear as in the case of a one-letter difference. Words with two letters different from each word are sequentially displayed as next candidates. When a correctly spelled word is found among these words, the subsequent operations are the same as described above.

As described in detail above, in this Roman word processor 1, the CPU 11 determines whether each word is correct or incorrect at the same time as each word is input, and there are no errors in the dictionary memory 12. A warning can be displayed by flashing English words spelled as ivy on the CRT9. Then, by operating the call key 6 for the blinking word, an English word with the same number of characters but one or two characters different in spelling can be retrieved from the dictionary memory 6.
2 can be extracted and displayed as the next candidate on the CRT 9. If you select a word with the correct spelling from among the next candidates and operate the selection execution key 8, you can change the blinking incorrectly spelled word to the correct English word. Can be replaced with a word.

In addition, when extracting the next candidate from the dictionary memory 12, the CPU 11 sets a word that is one or two letters different from the input word, and then searches for that word from the dictionary memory 12. First, it is determined whether a character string consisting of the replaced character and the character before or after it exists in the dictionary memory 12 by reading it from the frequency memory 13, and if it does not exist, the character string of the set word is Search from within the dictionary memory 12 is omitted. Therefore,
In the work of extracting the next candidate from the dictionary memory 12 by the CPU 11, unnecessary search processing can be omitted, so that the time required for extracting the next candidate can be shortened.

Then, the user enters the English word incorrectly.
You can easily check the blinking display on the CRT9 and select the correct spelling from among the next candidates on the CRT9, so there is no need to look up the correct spelling of the incorrect word using a dictionary or other means. This allows you to quickly correct English words.

In the above embodiment, the frequency memory 13 is searched for and read out whether or not a character string consisting of replaced characters exists. You may be able to find the desired word more quickly by reading it from the .

Furthermore, in the above embodiment, the frequency memory 13 stores the number of occurrences of two consecutive characters.
The number of occurrences of consecutive character strings of three or more characters may be stored in the frequency memory 13, and the character string corresponding to the replaced character may be searched based on the contents.

Effects As described in detail above, the present invention prints the spelling of an incorrectly spelled English word that does not exist in the dictionary memory 12 from among the English words inputted by the input device by operating the retrieval means 6. The following English words can be immediately displayed on the display unit 9 as the next candidates. By selecting the desired correctly spelled English word from among them, you can correct the incorrectly spelled English word. It can be performed easily and quickly and has excellent effects.
