Abstract

PURPOSE: To provide the spelling checker to be used easily for a user by preferentially presenting a word that seams to have been learned and be intended to be used by the user rather than a word that seems to be unknown to the user. CONSTITUTION: This device is provided with a check dictionary 3 for which various kinds of information corresponding to words are stored and further the respective registered words are divided into groups corresponding to the skill level of a general learning person, and a candidate preparing part 2 generates a similar character string corresponding to an input character string as the candidate of a proper answer. Then, a check dictionary retrieving part 5 possesses the information on whether the designated character string is registered on the ckeck dictionary 3 or not and which group that character string belongs to when it is registered, and a candidate output part 71 outputs the retrieved results of the proper answer candidates prepared by a candidate preparing part 4 in the order from the low skill level.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spell check device in a natural language processing device especially for foreign language learners.

[0002]

2. Description of the Related Art A spell check device is a device which points out a misspelling of a word in a text created by a word processor and provides a user with information necessary for correction such as correct spelling.

A conventional spell check device will be described below. FIG. 5 shows the configuration of a conventional spell check device.

The conventional spell check device has a check character string input unit 51 for inputting a character string for spell checking, a check character string holding unit 52 for holding an input character string to be checked, and a word. And a check dictionary 53 storing various information for the check character string, and a candidate creation unit 5 for generating similar character strings as correct answer candidates for the check character string.
4, a check dictionary search unit 55 that acquires information regarding whether or not the designated character string is registered in the check dictionary, and that the check dictionary search unit 55 searches the check dictionary 53 and finds that it is registered in the check dictionary 53. It has a search result holding unit 56 that holds information about confirmed correct answer candidates, and a candidate output unit 57 that displays the candidates held in the search result holding unit 56.

[0005]

However, in the above configuration, when the correct answer candidate confirmed to be registered in the check dictionary is presented to the user, the learning level of the user is not taken into consideration. The candidates that are unknown to the user are presented before the candidates that the user originally intended to write, which causes confusion for the user and is not easy for the user to use.

Further, in the above configuration, if the input character string is registered in the check dictionary regardless of the user's level, it is not judged as a spelling mistake. Therefore, when the user makes a spelling mistake, the resulting character string happens to be. There was a problem that the spelling mistake made by the user could not be pointed out when the word with the same spelling was registered in the check dictionary.

The present invention solves the above-mentioned conventional problems. First, for the first problem, a word that the user has learned and may have tried to use is unknown to the user. It is an object of the present invention to provide a spell check device that is easy for the user to use by presenting candidates based on the mastery level of the user, such as presenting the words in preference to likely words.

Another object of the present invention is to provide a spell check device that can detect spelling mistakes that cannot be detected by conventional spell check devices.

[0009]

In order to solve this problem, a spell check device according to the present invention firstly comprises a check dictionary for storing various information regarding words including a mastery level, and is based on the mastery level. It is configured to output correct character string candidates in order.

Secondly, an input means for inputting a character string for spell checking, a check dictionary for storing various information about words including a learning level, and a similar character string for the character string for spell checking are correct candidates. Creating means, a searching means for searching a character string to be spell checked from the check dictionary or a character string created by the candidate creating means, and a searching means for the character string created by the candidate creating means. Search result holding means for holding the search result, and candidate output means for outputting the search result held in the search result holding means means,
The candidate creating means generates a similar character string as a correct answer candidate when the character string to be spell checked cannot be searched from the check dictionary by the searching means, and the candidate output means is the word which is the search result held in the search result holding means. Are output in the order based on the mastery level included in the word.

Thirdly, in the second means, the candidate output means outputs the candidates in ascending order of learning level.

Fourthly, a check character string input unit for inputting a character string for spell checking, a check character string holding unit for holding the input character string to be checked, and various information for words are stored. , A check dictionary in which each registered word is grouped according to the learning level of a general learner, and a candidate creation unit that generates a similar character string as a correct answer candidate for the check character string, A check dictionary search unit that obtains information about whether the specified character string is registered in the check dictionary and, if registered, which group is included in the check dictionary, the search result of the check dictionary search unit, and the check result. A search result holding unit that holds information about correct candidates and their groups confirmed to be registered in the dictionary, and in order of increasing learning level It has a configuration that includes a candidate output unit for displaying the search results holding unit candidates held in the.

Fifth, in addition to the second to fourth means,
A caution word group holding unit that holds information about a word group for which the possibility of spelling mistakes should be considered for each learning level is provided, and the character string input by the input means is held in the caution word group holding unit, When the mastering level of the input character string in the caution word group holding unit is equal to the mastering level designated by the user, the candidate creating means creates a correct answer candidate for the input character string. ing.

[0014]

In the spell check device according to the first means of the present invention, correct character string candidates are output in the order based on the mastery level.

In the second, third and fourth spell checking devices of the present invention, first, the input dictionary itself is searched by the check dictionary searching section for a check dictionary to check whether the input character string is registered in the check dictionary. . If it is registered, it is determined that it is not a misspelling.

If not registered, the candidate creating unit generates a character string similar to the check character string, and the check dictionary searching unit searches the check dictionary for them. As a result, the registered word is stored in the search result holding unit together with the information regarding the learning level. Then, the candidates stored in the search result holding means by the candidate output means are output in the designated order based on the mastering level in the second means, and the candidates are output to the user in the order of lower learning level in the third and fourth means. By being presented,
It allows the user to find the intended word earlier in the candidates and is easier to use.

Further, in the fifth spell check device of the present invention, first, the character string itself input by the input means is searched, and if it is registered in the check dictionary, the word group holding unit of the caution word group is further searched. If the input character string is registered in the caution word group holding unit, and the master level specified by the user and the master level of the character string in the caution word group holding unit are equal, By creating a correct answer candidate for the character string by the candidate creating means, the possibility of misspelling is examined for the word belonging to the attention group for the user, and the word that happens to be the same as the result character string is checked in the check dictionary. Even if it is registered, it can be avoided that the spelling mistake made by the user cannot be pointed out.

【Example】

(First Embodiment) A first embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a check character string input unit, 2 is a check character string holding unit, 3 is a check dictionary, 4 is a candidate creating unit, 5 is a check dictionary searching unit,
Reference numeral 6 is a search result holding unit, and 7 is a candidate output unit.

The operation of the spell check device configured as described above when "thema" is input as a check character string will be described with reference to FIG. Here, the user is at the high school level, and the intended word is "th
In addition, the results shall be presented in ascending order of learning level.

First, when the character string "thema" is input by the check character string input unit, it is stored in the check character string holding unit. Then, first, the check dictionary search unit searches the check dictionary for the character string itself to check whether the character string is registered in the check dictionary.

Here, it is assumed that the check dictionary is not included. Then, the candidate creation unit generates character strings similar to the check character string, and the check dictionary search unit searches the check dictionary for them. As a result, the registered information is stored in the search result holding unit together with the information about the group to which it belongs.

In the following, "them" and "thec"
The candidates "a", "theta", and "theme" are
"Middle school", "General", "University",
Suppose that you were obtained as a member of a group called "high school". Here, the level of learning is "junior high school",
“High school”, “university”, and “general” are defined as high in this order.

In conventional spell checkers, they are presented to the user in some order, but always "t".
"hem" and "theme" are "theca" and "the"
It was not always presented before "ta".

In this case, since the user is designated as a high school level, in the conventional example, "theca" and "theta" which are unlearned words for the user are presented before "theme" intended by the user. There is a possibility,
This will be confusing for the user.

However, in the present embodiment, these are presented in ascending order of learning level, so the presentation order is "the
m "," theme "," theca "," thet
"a", and the user knows "th
"ca" and "theta"weren't confused
"theme" can be found.

Although "them" comes before "theme", since it is a word that the user has learned, the user is not confused.

As described above, according to the present embodiment, it is possible to provide a spell checking device that is easy for the user to use by including the mastering level in the check dictionary and outputting correct character string candidates in the order based on the mastering level. You can

The order of presentation is not the order of the learning level, but the learning level of the user is first presented, then the candidates of the level higher than the learning level of the user are sequentially presented, and the user is later ordered from the lower learning level. It is apparent from the present embodiment that the setting can be freely performed according to the user's preference, such as presenting up to the mastery level.

(Second Embodiment) A second embodiment of the present invention will be described below with reference to the drawings. In FIG. 3, 31 is a check character string input unit, 32 is a check character string holding unit, 33 is a check dictionary, 34 is a candidate creating unit, 3
5 is a check dictionary search unit, 36 is a search result holding unit, 37
Is a candidate output unit, and 38 is a caution word group holding unit.

The operation of the spell check device configured as described above when "putted" is input as the check character string will be described with reference to FIG. In addition,
Here, the word intended by the user is “put” (past tense)
Assume that Also, as a caution group, "general"
Shall be specified.

First, when the character string "putted" is input by the check character string input unit, it is stored in the check character string holding unit. Then, first, the check dictionary search unit searches the check dictionary for the character string itself to check whether the character string is registered in the check dictionary. Here, it is assumed that "putted" is included in the check dictionary as the past tense of "putt" (putting at golf) belonging to "general".

Then, in the conventional spell checker, "pu
"tted" is not detected as a misspelling, although it is different from the user's intention.

On the other hand, in the spell checker of the present embodiment, the group “general” to which “putted” belongs is a caution group and is the target of spell check. The check dictionaries are created, and the check dictionaries are searched for by them.

Here, assuming that the spell checker of this embodiment has a capability of presenting an actual inflection form as a candidate for a character string of incorrect utilization, it is "putted".
, “Put” is presented as a candidate.

As described above, according to the present embodiment, by providing the caution word group holding unit that holds the information on the word group for which the possibility of spelling error should be considered for each level of the learner, Regarding the words that belong to the caution group for users, the possibility of spelling mistakes is considered, and even if a word that spells the same as the resulting character string happens to be registered in the check dictionary, it cannot point out the spelling mistake that the user made. Can be avoided.

[0036]

As described above, according to the present invention, the candidates can be presented in the order in consideration of the mastery level of the user, and the spell check device which is easy for the user to use can be provided.

Further, by retaining information on word groups for which the possibility of spelling mistakes should be considered for each learning level, it is possible to detect spelling mistakes that cannot be detected as spelling mistakes by conventional spell checking devices according to each learning level. Is possible.
