Abstract

PURPOSE:To attain an effect equivalent to the deletion of a word from a plus dictionary by registering a character string expressing the word decided to be mistakingly spelled in a minus dictionary. CONSTITUTION:According to a system program stored in a program memory 10, a CPU 9 exchanges a signal between dictionaries 6-8 through a bus 11. First, a supplied word is checked to be present or not in the main dictionary 6. If so, the word is further investigated to be present in the minus dictionary 8. If so, it is decided to be mistakingly spelled. If not, its spelling is decided to be proper. If the supplied word does not exist in the dictionary 6, it is continuously checked to be present or not in the user dictionary (plus dictionary) 7. If so, its spelling is decided to be proper. If not, it is decided to be erroneously spelled.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electronic dictionary provided in a language processing device such as a Roman word processor, a Roman typewriter, or an electronic computer that handles character information.

(Prior art) In English word processors, English typewriters, etc.
Devices equipped with an electronic dictionary are known for checking whether or not there are any errors in the spelling of input words (spell check). This electronic dictionary generally consists of a main dictionary (usually composed of ROM (read-only memory)) and a user dictionary (usually composed of RAM (random access memory)).
), and the main dictionary stores the spellings of commonly used words, while the user dictionary stores the spellings of words used individually by each user. .

(Problem to be solved by the invention) However, according to the electronic dictionary as described above, if a character string that does not constitute a valid word is input to the language processing device, that is, a character string that is not registered in the electronic dictionary is input. If it is, it will be judged as a misspelling, but
When a word with a similar spelling is mistakenly entered instead of a certain word, it is not determined to be a misspelling, and there is a problem in that the input mistake is overlooked.

Specifically, for example, a character string meaning "calendar" is "calendar", and a character string having a similar spelling is "calender". In this case, even if you mistakenly enter "calendar" with the intention of entering "calendar", it will not be determined as a misspelling. because,"
This is because "Ca-Iender" has the meaning of "a machine that polishes paper, cloth, etc. with a roller," and is registered as a valid word in itself.A similar example is
Even if you incorrectly enter “runes” as a variation of the verb “run” when you should have entered “runs”, “ru
It is considered to be the plural form of ``ne (ancient Norse character)'' and is not determined to be a misspelling.

In that case, considering that the usage frequency of "calender" and "runes" is extremely low, if the configuration is configured so that the user can delete "calender" and "runes" from the main dictionary if desired, "calendar" can be deleted from the main dictionary. “calen
der” or enter the variation of “run” as “run”.
es" can be detected as a misspelling. However, as a practical matter, as mentioned above, the main dictionary is usually configured with ROM, so it is difficult to change the contents of the main dictionary. In the unlikely event that a word is incorrectly spelled in the main dictionary, it cannot be easily rewritten, resulting in a problem that an accurate spell check function cannot be obtained.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides an electronic dictionary consisting of a memory device, in addition to a conventional plus dictionary that registers the spelling of words as a reference for spell checking. A minus dictionary is provided, and by registering a desired word among the words registered in the plus dictionary in the minus dictionary, the word is determined to be misspelled. That is, by registering a character string representing a word to be determined as a misspelled word in the minus dictionary, the same effect as that of deleting the word from the plus dictionary can be obtained.

It is preferable that the ``-'' plus dictionary is configured with a ROM area (corresponding to the main dictionary) and the RAM area (corresponding to the user dictionary), and the ``-'' minus dictionary is configured with RAM.

(Examples) Hereinafter, the present invention will be described in more detail based on Examples with reference to the accompanying drawings.

FIG. 2 shows the general configuration of a language processing device to which the present invention can be applied. The device includes an input device 1 (
For example, a keyboard device, a tablet device, an OCR (optical character reader), a magnetic tape device, etc.), and a storage device 2 (for storing edited character information input from the human-powered device I).
For example, core memory, IC memory, magnetic disk, etc.)
An output device 3 (for example, a printer, a display device, a magnetic tape, etc.) that outputs the character information stored in the storage device 2
(magnetic disk device, etc.) and an electronic dictionary 4 (e.g. core memory, IC memory, magnetic disk, ROM, RAM, etc.) that provides information regarding the alignment of spelling information of character and word data stored in the storage device 2. ), and a control device 5 (for example, a computer) that controls the exchange of signals between the devices 1 to 4.

As shown in FIG. 1, the electronic dictionary 4 consists of a ROM,
Main dictionary 6 that registers the spellings of commonly used words
, a user dictionary 7 consisting of RAM and registering words used individually by the user, and a minus dictionary consisting of RAM registering the spellings of words that should be determined to be misspelled among the words registered in the main dictionary 6. 8.

The user dictionary 7 and the minus dictionary 8 are backed up in memory using a known method to preserve the stored contents.

The electronic dictionary 4 includes a CPU (central processing unit) 9 dedicated to processing on the dictionary 4 side in addition to processing on the main body side.
9 exchanges signals with each of the dictionaries 6 to 8 via the bus 11 based on the system program stored in the program memory 10. Further, the CPU 9 is connected via a bus 12 to an I/F driver/receiver 13 on the main body side in serial or parallel fashion.

Next, spell check processing using the dictionary 4 will be explained in detail based on the flowchart.

In this embodiment, the main body side and the dictionary 4 side operate separately, and when a spell check request is issued from the main body side to the dictionary 4 side, the CPU 9 of the dictionary 4 performs the spell check as shown in the flowchart (a) on the right side of FIG. Perform spell check processing according to the following.

At that time, the alphabetic character string of the word to be spell checked is transmitted from the I/F driver/receiver 13 on the main body side to the CPU 9 on the dictionary 4 side by interrupt processing according to the flowchart (b) on the left side of FIG. . below,
Explain in detail.

In the flowchart of FIG. 3(a), when a spell check request is issued from the main unit, step 0 (SO...
- Initial settings of various conditions, etc. are performed in steps (hereinafter referred to as S). The flag is turned off in Sl. This flag is used to determine whether or not a spell check process is being performed, and when the flag is on, it indicates that the process is being performed.

In S2, a CTC (control timer clock) that controls the timing of interrupts from the main unit is started to enable interrupts at predetermined time intervals, and in S3, spelling is performed by interrupts from the main unit (described later). Wait until the word to be checked is sent.

In S3, if the word to be spell checked is sent from the main unit and the flag is turned on, the process proceeds to S4, where the spell check is performed according to the flowchart in Figure 4 (described later), and the result is sent to the main unit in S5. Output. Next, return to Sl, turn off the flag, and prepare to check the spelling of the next word.

Next, interrupt processing will be explained.

In the flowchart of FIG. 3(b), when character data of a word to be spell checked is supplied to the CPU 9 by an interrupt, it is determined in S6 whether the flag is on or not, and the flag is off, that is, the spell check is executed. If not, the input command in S7 causes the supplied character data to be stored in the buffer sequentially for each month character. On the other hand, S
If the flag is on in step 6, that is, spell checking is in progress, the process returns to the routine of FIG. 3(a) without storing the supplied character data in the buffer.

In S8, it is determined whether or not the supplied data is a punctuation code representing the end of a word. If no, the process returns to the routine of FIG. 3(a), and if yes, S
After 9J, the flag is turned on, and then the above C
After the TC is set to a disabled state, that is, an interrupt from the main body side is disabled, the routine returns to the routine shown in FIG. 3(a).

Next, the spell check processing procedure will be explained based on the flowchart of FIG.

If word information is supplied in Sll, the word is converted into a normal code or hash code in S12.

Continuing on, in Sl3, it is first searched to see if the supplied word exists in the main dictionary 6, and if it exists in the main dictionary 6, the process proceeds to S14, where it is further searched to see if the word exists in the minus dictionary 8. Ru. If it exists in the minus dictionary 8, it is determined that it is a misspelling, and if it does not exist, it is determined that the spelling is correct.

In Sl3, if the supplied word does not exist in the main dictionary 6, a search is continued to determine whether the word exists in the user dictionary 7 (Sl5), and if it exists in the user dictionary 7, the spelling is determined to be correct. is determined, and if it does not exist, it is determined to be a misspelling.

(Effects of the Invention) As described above, in the present invention, since a minus dictionary is provided in addition to the conventional plus dictionary, the following advantages arise.

(1) As mentioned above, two words with similar spellings, one used more frequently and the other less frequently used (“c
``alendar'' and ``calendar''), by registering a less frequently used word (such as ``calender'') in the minus dictionary, you can prevent words that are used frequently when they are accidentally registered in the minus dictionary when you intend to input them. When you enter a word that is used infrequently, it can be determined as a misspelling.If you wish to use a word that has been registered in the minus dictionary, you can simply delete that word from the minus dictionary.

In that case, if the minus dictionary is configured in RAM as described above, registration and deletion from the minus dictionary can be easily performed.

(11) If the wrong spelling of a word is registered in the plus dictionary, registering the same spelling in the minus dictionary is equivalent to deleting the incorrectly spelled word from the plus dictionary. effect can be obtained, thereby preventing errors in spell checking.
