Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention detects a spelling error in each word when a sentence is created in English or French and presents a correct spelling candidate to the operator. The present invention relates to a spelling error correction method and a spelling error correction device that correct a spelling error by selecting one.

[0002]

2. Description of the Related Art In recent years, with the internationalization of society, the number of opportunities to handle foreign languages including English has greatly increased. And among these foreign languages, there is a spelling error correction device called a spell checker or a spell collector to support the writing of sentences in a language using an alphabet such as English or French.

An English spell checker, which is an example of this conventional spelling error correction device, has an input means 31, a spelling error detection means 32, a candidate word generation means 33, and a spelling correction dictionary 34, for example, as shown in FIG. The display means 35 and the selection means 36 are provided. The input means 31 is for inputting an English sentence. The spelling error detection means 32 detects a spelling error in an English word. The candidate word generation means 33 generates a correct spelling candidate for the misspelled word. The spelling correction dictionary 34 holds word information for spelling correction. The display means 35 displays the candidate words. Selection means 3
6 is for the operator to select a candidate word.

In this conventional English spell checker, an English sentence is input by the input means 31, and the spelling error detection means 32 checks whether or not each word in the input sentence is spelled correctly. At this time, the spelling of each word and the spelling in the spelling correction dictionary 34 are matched. For this matching, for example, JLPeterson "ComputerPr
ograms for Spelling Correction ", Springer-Verlag,
1980. If there is a possibility of misspelling as a result of matching with the spelling correction dictionary 34, the candidate word generating unit 33 generates correct spelling candidate words and the display unit 35 presents them to the operator. . FIG. 6 shows an example of the display screen. The operator selects the correct spelling word from the presented candidate words by the selection means 36. In the case of FIG. 6, a candidate word is selected,
By pressing the "replace" button, the corresponding word in the original sentence is replaced with the correct spelling word. At this time, if the spelling is correct, the spelling correction can be passed. If the candidate word does not have the correct spelling word, the correct spelling word can be registered in the user dictionary.

[0005]

However, in the above-mentioned conventional configuration, there is a problem in that the selection of the candidate word is often erroneous because the information regarding the candidate word is insufficient. In particular, when the language used is a foreign language, selection is often mistaken because the meaning or part of speech of the candidate word is unknown. To avoid such a selection error,
The user had to refer to an English-Japanese dictionary or the like in order to look up the part of speech and semantic information of the candidate word.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a spelling error correction method and a spelling error correction device which can correct spelling easily and accurately.

[0007]

According to a first aspect of the present invention, a spelling correction dictionary for storing spelling information of a word and a part-of-speech / semantic dictionary for storing part of speech and meaning information of the word are used. Referring to the spelling error detection step of detecting a spelling error in the input word, and referring to the spelling correction dictionary, generate a correct spelling candidate for the spelling error word detected in the spelling error detection step. In the candidate word generating step, the part-of-speech / semantic information generating step of generating the part-of-speech and meaning information of the candidate word generated in the candidate word generating step with reference to the part-of-speech / semantic dictionary, and the candidate word generating step And a display step of displaying the generated candidate word and the part of speech and meaning information generated in the part of speech / semantic information generating step. It is characterized in that.

According to a second aspect of the present invention, a spelling correction dictionary for storing spelling information of a word, a part of speech / semantic dictionary for storing part of speech and meaning information of a word, input means for inputting a sentence, and the spelling correction. A spelling error detecting means for detecting a spelling error of a word input to the input means by referring to a dictionary, and a correct spelling error word detected by the spelling error detecting means for referring to the spelling correction dictionary A candidate word generating means for generating a spelling candidate; a part-of-speech / meaning information generating means for generating a part-of-speech and meaning information of the candidate word generated by the candidate word generating means by referring to the part-of-speech / meaning dictionary; Display means for displaying the candidate words generated by the candidate word generation means and the part of speech and meaning information generated by the part-of-speech / meaning information generation means, and a display means for displaying the candidate words. Operator one of the candidate words is characterized by comprising a selection means for selecting.

[0009]

According to the first aspect of the invention, in the spelling error detecting step, the spelling correction dictionary is referenced to detect the spelling error of the input word. In the candidate word generation step, the spelling correction dictionary is referenced to generate a correct spelling candidate for the spelling error word detected in the spelling error detection step. In the part-of-speech / semantic information generating step, the part-of-speech / semantic information of the candidate word generated in the candidate word generating step is generated by referring to the part-of-speech / semantic dictionary. In the displaying step, the candidate word generated in the candidate word generating step and the part of speech / semantic information generated in the part of speech / semantic information generating step are displayed.

In the invention of claim 2, the spelling correction dictionary stores spelling information of words. The part-of-speech / semantic dictionary stores the part-of-speech and meaning information of a word. The input means is for inputting a sentence. The spelling error detection unit refers to the spelling correction dictionary and detects a spelling error in the word input to the input unit. The candidate word generation unit refers to the spelling correction dictionary and generates a correct spelling candidate for the spelling error word detected by the spelling error detection unit. The part-of-speech / semantic information generating means refers to the part-of-speech / semantic dictionary and generates the part-of-speech and semantic information of the candidate word generated by the candidate word generating means. The display means displays the candidate word generated by the candidate word generating means and the part of speech and meaning information generated by the part of speech / semantic information generating means. The selection means is for the operator to select any of the candidate words displayed by the display means.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a block diagram of a spelling error correction apparatus according to an embodiment of the present invention. This spelling error correction apparatus includes an input unit 1, a spelling error detection unit 2, and a candidate word generation unit 3.
A spelling correction dictionary 4, a part of speech / semantic information generating means 5,
A part-of-speech / semantic dictionary 6, a display means 7, and a selection means 8 are provided. The input unit 1 is composed of a keyboard, for example, and is used by the operator to input a sentence.
The spelling error detection unit 2 refers to the spelling correction dictionary 4 and detects a spelling error in a word included in the sentence input from the input unit 1. The candidate word generation unit 3 refers to the spelling correction dictionary 4 and generates a correct spelling candidate for the spelling error word detected by the spelling error detection unit 2. The spelling correction dictionary 4 stores word spelling information. The part-of-speech / semantic information generating means 5 refers to the part-of-speech / semantic dictionary 6 to generate the part-of-speech and meaning information of the candidate word generated by the candidate word generating means 3. The part-of-speech / semantic dictionary 6 stores the part-of-speech and meaning information of a word. The display means 7 is composed of, for example, a CRT or a liquid crystal display device,
The candidate word generated by the candidate word generating means 3 and the part of speech and meaning information of the candidate word generated by the part-of-speech / meaning information generating means 5 are displayed. The selection unit 8 is composed of, for example, a mouse or a keyboard, and is used by the operator to select a candidate word. The spelling error detection unit 2, the candidate word generation unit 3, and the part-of-speech / semantic information generation unit 5 are realized by a CPU, and the spelling correction dictionary 4 and the part-of-speech / semantic dictionary 6 are realized by a ROM or a RAM. This spelling error correction device may be realized as a dedicated machine or a general-purpose computer.

Next, the operation of the spelling error correction apparatus will be described with reference to the flow charts of FIGS. First, when the operator inputs a sentence using the input means 1 (step S1), it is determined whether or not the "spell check" button has been pressed by the operator (step S).
2). That is, it is determined whether or not the operator has operated the cursor key or the execution key of the mouse or the keyboard to select the spell check. In addition, the concrete meaning of the operation "press the button" that follows is also "spell check".
Similar to the case of the button, the operator operates a cursor key or an execution key of a mouse or a keyboard to select a desired operation. If the spell check button has not been pressed, the process returns to step S2 to enter the standby state. If the spell check button is pressed, it is determined whether or not an unchecked word remains in the input sentence (step S3), and if not, the spell check process ends. If an unchecked word remains, the spelling error detection means 2 extracts the next word (step S4) and checks the spelling of the word (step S).
5). At this time, the spelling correction dictionary 4 is referred to. That is, if the spelling correction dictionary 4 stores correctly spelled words and the input original word is in the spelling correction dictionary 4,
The spelling is judged to be correct, and if not, it may be incorrect. As a result of the check, it is determined whether or not the spelling is incorrect (step S6). If not incorrect, the process returns to step S3 to check the next word. If there is a possibility that the spelling is incorrect, the candidate word generating means 3 refers to the spelling correction dictionary 4 and determines the correct spelling candidate word corresponding to the original word (step S7). Next, the part-of-speech / semantic information generation means 5 refers to the part-of-speech / semantic dictionary 6 to determine the part-of-speech and meaning information of the candidate word (step S8).
Next, the display means 7 displays the obtained candidate word and its part of speech and meaning information as shown in FIG. 4 and presents it to the operator (step S9). As a result, the operator selects the candidate word that seems to be correct by the selecting means 8 while referring to the part of speech and the semantic information of each candidate word. For example, in FIG.
In the case of, the version is specified from the candidate words by operating the mouse or the keyboard. Next, it is judged whether or not the candidate word is selected by the operator (step S10), and if selected, it is judged whether or not the "replacement" button is pressed by the operator (step S11).
If it has not been pressed, the process returns to step S11 to enter the standby state. When the "replace" button is pressed, the original word "perversion" in the input sentence is replaced with "version" (step S12), and the process returns to step S3 to check the next word. At this time, the designation of the candidate word can be changed before the "replace" button is pressed.

If there is no correct word among the candidate words, that is, the word intended by the operator, the operator may press the "pass" button. That is, if the candidate word is not selected in step S10, it is determined whether or not the "pass" button is pressed (step S13), and if it is pressed, the process returns to step S3 and the spelling correction is not performed for the current word. Move on to check the next word.

If the original word determined to have a possibility of spelling error by the check is a proper noun such as a person's name and is not actually an error, the original word should be registered in a user dictionary (not shown). You can That is, if the "pass" button is not pressed in step S13, it is determined whether the "register" button is pressed (step S1).
4) If pressed, the original word is registered in the user dictionary (not shown) (step S15), and the process returns to step S3 to process the next word. At this time, the operator can also register the part of speech and the semantic information together with the original word in the user dictionary.

If the "register" button is not pressed in step S14, it is determined whether or not the operator has pressed the "end" button (step S16). If not, the process returns to step S10 to enter the standby state. If the "end" button is clicked, the spell check process ends. In this way, when displaying the candidate word, not only the spelling of the word but also the part-of-speech and the semantic information of the word are simultaneously displayed by the display means 7, so that the candidate word can be easily selected and the spelling can be easily corrected. You can do it accurately.

Although the spelling correction dictionary 4 and the part-of-speech / semantic dictionary 6 are separately provided in the above embodiment, they may be combined into one dictionary. Further, in the above embodiment, the input means 1 is constituted by the keyboard and the operator inputs the sentence, but the output from the character recognition device or the like may be inputted to the input means 1. Alternatively, the sentence stored in an information storage medium such as a flexible disk may be read by the input unit 1.

Further, in the above embodiment, the operator operates the mouse or the keyboard to select the desired motion, but the operator touches the display screen of the display means 7 to select the desired motion. It may be configured to do so.

[0018]

As described above, according to the present invention, a spelling correction dictionary is created using a spelling correction dictionary that stores spelling information for words and a part-of-speech / semantic dictionary that stores word part of speech and meaning information. The spelling error of the input word is detected by referring to the spelling correction dictionary, the correct spelling candidate for the detected spelling error word is generated, and the part of speech / semantic dictionary is referred to. It generates the part-of-speech and meaning information of the candidate word and displays the generated candidate word and part-of-speech and meaning information.When displaying the candidate word, not only the spelling of the word but also the part-of-speech and meaning information of the word are displayed. Since it can be presented to the operator at the same time, the candidate word can be easily selected, and the spelling can be corrected easily and accurately. In addition, it is not necessary to search the English-Japanese dictionary or the like to check the meaning of the candidate word. Furthermore, since the part-of-speech and semantic information of each candidate word are displayed, it is also effective for learning words.
