Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and method for analyzing spelling,

The present invention relates to a system and method for analyzing Hangul spelling checklists, and more particularly, to a spelling checklist having a constant degree of difficulty to improve the reliability of the test. When the examinee sets goals, he or she extracts the items from the question database In addition, it is possible to automatically generate test pages and to extract optimal items from the question database for the target level of the student set by the examiner so as to generate an optimal test page. Further, the test page prepared by the examinee is scanned It can be used as teaching materials or self-directed learning materials by providing information about error analysis and predicted development level of testee by analyzing scoring result, The test result of the testee accumulates So that the current level and progress of the testee can be easily ascertained through comparison with the top 30% students, and the reliability and validity of the test result interpretation can be secured by continuously accumulating and updating the test results through the repository system And a system for analyzing the results of the test.

The Korean Spelling Developmental Test (Yang Min-hwa, Bae Jong-min, 2014) and KOLRA (Korean Reading Test, Bae Soo-young, Kim Mi Bae, Yoon Hyo-jin, Chang Sang Min) are standardized test tools to measure spelling ability.

The Korean spelling development test corresponding to the former is standardized until the first to third grades of elementary school. There are two types of the spelling test, one is phonological type and the other is morpheme type. This test is similar to the traditional dictation method in which the examinee writes words and example sentences. The test result is verified with the naked eye, the score is calculated by direct scoring, and the standard score It is inconvenient to use and it is difficult to secure objectivity in the evaluation result. In addition, the score calculation process is not easy because it is composed of whole words and target phonemes. The test paper consists of only four types of phonemic type (type and bell type) and type small type (type and bell type) It was insufficient.

 The latter KOLRA test is standardized for elementary school grades 1-6, and there is a dictation test in the subregion of the writing evaluation area. This test consists of writing words and sentences. The test results are calculated by the self-scoring by the examiner, and the standard score is calculated by inputting the number of origin in the computer. However, since this test is also composed of one type, it is difficult to check the progress of learning, and since the test result provides a standard score based on the total score of dictation, it is difficult to analyze the spoken ability level of the testee in detail .

All of the two tests described above can only provide a spell-level test of the testee's age, and they can be tested for spelling (eg, difficulty in beginning, difficulty in phonological change, etc.) And there is a problem that it is difficult to provide information for linking the evaluation result with the arbitration because various inspection sites are not provided for conducting the progress inspection. In addition, since the knowledge of Korean language knowledge and spelling development is required in order for the examinee to directly interpret the test results of the testee, there is a problem in that it is difficult to interpret the test if there is no expert, and there is a lack of consistency and objectivity.

On the other hand, in Korean Patent Laid-Open Publication No. 2001-0079233 (published on August 22, 2001), which is related to a test paper automatic generation system by extracting general test items, a learner is given a mathematical problem consisting of a plurality of terms A learning problem generation system, comprising: a problem generation rule in which a distribution of a number of terms and a relationship between numbers of the terms are set; a difficulty level is automatically set by analyzing a learning ability of the learner; The problem generation rule is searched according to the learning contents of the question creation rule, and a problem generation is generated in real time by generating a random number using the retrieved problem generation rule, and is provided to the learner. , You can find the questionnaire including the question It is not possible to provide a means for securing the reliability of the test because the scores obtained from the respective tests have the same meaning, and furthermore, the test results are continuously accumulated and updated, And does not provide a structure for facilitating the understanding of the level and the degree of progress (degree of progress), and furthermore, it does not provide a structure for verifying additional preliminary questions to be added to the question bank.

As another related prior art, a method for examining and scoring test questions having different selection arrangements on the Internet is disclosed in Korean Patent Laid-Open Publication No. 10-2010-0111819 (published on Oct. 18, 2010) The candidate accessing a test question and question system on the Internet and requesting a test question for learning; Generating a plurality of individual test papers comprising test questions having different selection arrangements according to a request of a candidate; Sending a test sheet to a test taker's terminal requesting a test question together with individual test papers randomly called out among a plurality of individual test papers; The candidate who receives the individual test sheets and the answer sheet through the terminal creates an answer for the individual test sheet and transmits the answer sheet to the test question drafting and scoring system; And the test question essay and scoring system are used to mark the candidate's answer sheet. However, this technique also has the same meaning in the scores obtained from each test, And the test result is continuously accumulated and updated so that it is possible to easily grasp the current level and the improvement level (progress of the spelling ability) of the subject And that it is not able to provide a structure for the verification of additional preliminary questions to be added to the question bank.

Korean Patent Publication No. 2001-0079233 Korean Patent Publication No. 10-2010-0111819

Furthermore, by analyzing the error pattern of the testee with the average error pattern of the age range of the examinee, It is preferable to additionally include an age-based error pattern database (not shown) constructed from accumulated test results of a plurality of testees so as to provide analysis results.

Hereinafter, a process of generating a Hangul spelling checker according to an embodiment of the present invention will be described with reference to the flowchart of FIG. 4A.

First, the function of the main constituent part of the analysis system for generating and testing the Hangul spelling checker according to an embodiment of the present invention can be implemented through a computer program such as a Hangul spelling check paper generation program, for example, When the program is executed (S101), the inspector inputs unique information of the examinee and the inspection target through the input unit 110 (S102, S103). As the inspection target, the evaluation target such as initial value, vowel, A target can be set and an evaluation level target such as a higher difficulty level including the upper 30% level or the upper 10% level arbitrarily selectable by the examiner as the target standard of the testee's spelling ability can be set. Next, the item extraction unit 141 of the test sheet control unit 140 extracts a selection item and an additional preliminary item from the spelling test item database 130 (S104) (Sejong corpus, etc: https://ithub.korean.go.kr/user/noticeView.do) can be constructed as a question bank. In the Sejong corpus, words related to the curriculum of each grade are extracted, , And 10-fold of the extracted items are stored in the question bank and stored and managed as preliminary items. The item extraction unit 141 selects the selected items as the items constituting the spelling examiner among the preliminary questions. On the other hand, among the selected items, items that reflect the content of each grade level and have moderate degree of difficulty and differentiation are used as common items commonly used in many spelling test sites, and the scoring results of the answers It is not reflected in the final score. It is used to equalize the meanings of scores derived from different examiners and to ensure homogeneity in score interpretation.

 According to the present invention, in the spell checking sheet generating and storing unit 142, a spell checking sheet is generated and stored using a selection item extracted by the item extracting unit 141. First, The modeling and algorithm is applied to generate the items of the whole test in a single dimension. The items are selected by selecting one of the following parameters or non-parametric models according to the scale of the data pool or the purpose of the test.

1. Parametric and nonparametric models:

① Nonparametric model: The nonparametric model is used in the following two cases. First, in the early stage, the number of testees is small, so it is often not appropriate to use a statistical model in which the ability, difficulty, and discrimination of the testees are distributed. In the beginning, it is appropriate to use a nonparametric model because the distribution of data pools (data pools stored as selection items in the spelling check item database 130) is not a normal distribution. Second, we set the target level (eg, upper 30% of the spelling level by age) and use the nonparametric model when we want to check whether the testee has reached. If you set the goal level, if you set the top 30% of the spelling level by age or grade, questions with high difficulty level at the grade or age level will be extracted through the nonparametric model.

② Parametric model: It is a model that generates questions when the number of test cases accumulated in the data pool accumulates, and the difficulty and discrimination of the testees and the items form a specific distribution, that is, a normal distribution.

2. Using EM algorithm and MMLE

① EM algorithm:

The EM algorithm is an effective iterative algorithm used when estimating the most probable model when no information is determined. That is, as a method for estimating a model parameter when it is not known, the probability that observation data X is generated from this model (lambda_0) is calculated at the initial stage in which the model variable is set at random or by some other method do.

  P (X | lambda_0)

Now, we define a new model with a very small modification of the variables inside the model as lambda_1, then again find the posterior probability of the observed data and determine what is larger P (X | lambda_1). This process is repeated to stop P (X | lambda) for the new model lambda if it is less than the previous model (if the likelihood is smaller). E and M steps (see FIG. 5).

 - Step E (E Step): Assuming that the testee's ability level is fixed, estimate the degree of difficulty and discrimination of the item, and then estimate the degree of difficulty and discrimination of the item. Because there is no information about difficulty, discrimination, and testee level, both estimates are made.

 - M Step: At this stage, it is a step to find out the possibility of representing the difficulty of the item, the degree of discrimination and the level of the testee best.

3. Using the two-factor, multi-item question model considering item difficulty and discrimination, construct a question by choosing one of the two questions or multi-item questions to construct the item that fits the purpose of question generation.

① This item is a question that scored the type (eg, basic beginner, basic vowel, basic vowel, etc.) or words that are expected to be seen in one item as zero and one point. There are 1 parameter model, 2 parameter model, and 3 parameter model. The model is decided according to the purpose of inspection.

  - 1 Parametric Model: When determining the test taker's spelling level

  - 2 Parametric Model: When trying to distinguish difficulty level of item, attainment level of testee's spelling ability

  - 3 parameter model: It is used to estimate difficulty, discrimination, and guessing,

② Multi-item Question: The multi-item item estimates one discrimination and two difficulty levels for each item using the generalized partial credit model. That is, each difficulty corresponding to each partial score can be calculated, and it can be interpreted as difficulty to receive more than zero point, difficulty to receive more than one point. When calculating the score of each item, the generalized subscore model can be used to calculate the scores of the testee.

As described above, the process of generating the spelling checker is performed, and the spelling checker, which has been created, is stored in the form of a file in the subject data base DB 120 as inspection related data associated with the subject information of the subject (S105).

Then, the completed spelling checker is outputted through the spelling checker output unit 150 (S106).

Next, when the testee's answer to the output spelling test sheet is completed, that is, when the spelling test is completed, the process of scoring the completed spelling test sheet and analyzing the result is performed. This specific process is shown in the flowchart of FIG. .

First, among the functions of the main constituent part of the analysis system for generating and testing the Hangul spelling checker according to an embodiment of the present invention, the scoring process of the spelling checker and the analysis of the examination result are also implemented through a computer program such as a Hangul spelling checker examination result analyzing program The inspector may execute the Hangul spelling checker examination result analysis program (S201), and the spelling checker imaging unit 160 may scan the spelling checker completed in the form of an image file by using a device such as a camera or a scanner (S202). The spelling checker scoring unit 143 extracts a character from the stored image file and compares the extracted character with the spelling checker file stored in the subject DB 120 to perform scoring (S203) do. In addition to the evaluation items included in the item set in the scoring process, in the case of the basic items used for comparison, which are used as indicators for relatively objectifying the final score of the testee, Is not directly incorporated into the final score but is used as an indicator of relative objectivity of the final score of the examinee and a new additional preliminary item added to the spelling checklist indicates that the additional preliminary item has a goodness as a selection item And is used for the purpose of being evaluated.

The scoring result analyzing unit 171 of the result analyzing unit 170 analyzes the scoring result (score, current level, progress degree) of the examinee by using the result analyzing unit 170 The error analysis unit 172 derives the error analysis result, and the development level analysis unit 173 derives the phoneme prediction development level analysis result and displays it on the display unit 180 (S204a).

In addition, according to the embodiment in which the preliminary item analyzing unit 174 is additionally configured in the result analyzing unit 170 as in the embodiment shown in FIG. 3, the preliminary item analyzing unit 174 further includes an additional preliminary question (S204b1) from the result of separate scoring for the spelling check item (S204b1), and when it is determined to be a suitable item as a result, the selection item for spelling check is stored in the spelling check item database 130 (S204b2) .

On the other hand, the error analysis performed in the concrete analysis process of the spelling ability evaluation is performed by the words included in each item by the preset analysis program. In the analysis program of this embodiment, the word of the item is first subdivided into phonemes and the accuracy of writing (error occurrence) is determined for each subdivided phoneme unit. Phonemes are the minimum units of sound that distinguish the meaning of a word from the speech system of the language. For example, in the case of Korean, consonants 'ㄷ' and 'ㄸ', which are the first sounds (initials) in 'moon' and 'daughter', are phonemes with distinctive functions that distinguish the meanings of the two words. Also, in the case of 'moon' and 'stone', the neutral vowels 'a' and 'ㅗ' are the phonemes that distinguish the meaning of the two words. On the other hand, the consonant 'a', which is a consonant in the case of 'Axis' and 'Duck' in the 'Soccer Duksu', is the same phoneme, but the accuracy of pronunciation may appear differently in relation to other adjacent phonemes. In the case of pattern analysis, instead of evaluating only whether or not the phonemic unit distinguishing words is accurately recognized and dictated, the error frequency generated by the phoneme types such as the leading, neutral, And the analysis result of the error pattern is derived. Meanwhile, in addition to the error frequency and the alternative phoneme analysis for each phoneme type, it may include a phoneme type that is erroneously recognized in relation to an adjacent phoneme and an analysis criterion for each of the error patterns for deriving an analysis result for identifying the alternative phoneme type. Various other types of error-pattern-specific analysis criteria are available.

At this time, as a further embodiment according to the present invention, analysis may be performed in order to further analyze the accuracy and error pattern of spelling dictation and to produce the following additional analysis results. For example, in order to improve the spelling ability of a testee in an error pattern state such as a testee, a phonics development is performed by analyzing the level of the error pattern calculated through error analysis of the spelling test, In this paper, we propose a phonemic phonological model which is based on the phonemes of each age group. The phonemic phonemes of the age group Qualitative analysis of error patterns by comparing and analyzing with average error patterns (for example, when compared with average error pattern of age group, it can be classified into error pattern that shows error with small frequency in various phonemes or error pattern which shows high frequency in specific phoneme ; Qualitative part of error pattern ) It can be provided.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments. Those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope of the appended claims, It would be too obvious to belong to. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
