Description

  The present invention relates to an information processing apparatus or the like that constructs a word dictionary having information on difficulty levels.

  In the conventional information processing apparatus, various effective processes are performed using the information on the degree of difficulty. For example, in the first conventional information processing apparatus, an evaluation value of an objective difficulty level of a document can be obtained using dictionary data in which an objective difficulty level is assigned to a registered word. (For example, refer to Patent Document 1).

  Further, in the second conventional information processing apparatus, the difficulty level for each reading of kanji is stored in the kanji learning level dictionary, the difficulty level is designated, and each word including kanji is assigned each difficulty level. Words that are difficult to read are stored in the conversion result dictionary among the conversion results corresponding to the levels, the document is analyzed using the dictionary, and the level of difficulty equal to or higher than the level of difficulty specified earlier in the document is read. The kanji is converted into hiragana, the kanji mixed with hiragana is searched from the conversion result dictionary, and all the words in the document are converted into hiragana. (Patent Document 2).

  The third conventional information processing device supports the creation of more natural foreign language documents for people who have insufficient knowledge of words and grammar in the target foreign language using difficulty level information. (Patent Document 3).

Further, in the fourth conventional information processing apparatus, output display is performed in a form corresponding to the content of the input sentence using the difficulty level for the word (Patent Document 4). With this information processing device, for example, when a simple sentence that a child reads is input, the output form is changed so that it is output in hiragana, so that even a child who cannot read kanji is output and displayed. Can read the text.

  However, in the conventional first to fourth information processing devices, when building a dictionary of words having information on the difficulty level, since there is no technology for adding words with information on the difficulty level to the dictionary, There was a problem that new words could not be added to the dictionary as words of appropriate difficulty.

  More specifically, for example, the first evaluation (test etc.) allows a number of evaluators to evaluate the difficulty level of a word, and a first dictionary having a large number of words with information about the difficulty level can be constructed. Let's say. Next, for example, in the second evaluation, a new word could not be inserted into the first dictionary as a word having difficulty level information. That is, since many evaluators who performed the first evaluation and many evaluators who performed the second evaluation are usually different, the difficulty level of the word that is the first evaluation result is the same index, and It is not appropriate to construct a word dictionary having information on the difficulty level by comparing the difficulty levels of the words that are the second evaluation result. Even if the evaluation of the difficulty level of the word is performed by the same evaluator, the difficulty level in the first evaluation and the difficulty level in the second evaluation are exactly the same over time. Evaluating and inserting new words into the first dictionary has made it difficult to build a dictionary of word groups with appropriate difficulty information.

  In view of such a problem, the present invention normalizes information on the difficulty level when adding a word to which the information on the difficulty level is added to the dictionary, and converts the word to which the information on the appropriate difficulty level is added into the original dictionary The purpose is to add to.

  The information processing apparatus according to the first aspect of the present invention is the first difficulty information and second information of the word, which is information about the result of the evaluation on the first difficulty of the word and the word information that is the information of the word. 1 or more of the first word difficulty information having the second difficulty information, which is information on the result of the evaluation on the difficulty, and the second difficulty information having the word information and the first difficulty information A first word difficulty level information storage unit storing at least one first word difficulty level information, and a second word difficulty having word information and second word difficulty level information but not having first difficulty level information First difficulty information included in the first word difficulty information having second difficulty information from the second word difficulty information storage section storing one or more degrees information and the first word difficulty information storage section And first acquisition to acquire one or more information having second difficulty information A second acquisition unit that acquires one or more pieces of information having second difficulty level information from the second word difficulty level information storage unit, and one or more first difficulty level information and second information acquired by the first acquisition unit Based on the difficulty information and the one or more second difficulty information acquired by the second acquisition unit, the first difficulty of one or more word information corresponding to the second difficulty information acquired by the second acquisition unit A first difficulty level information calculation unit that calculates degree information, and a first difficulty level information calculation unit that stores at least one first difficulty level information calculated by the first difficulty level information calculation unit as first difficulty level information of corresponding word information This is an information processing apparatus including a difficulty level information storage unit.

  With this configuration, when adding a word with difficulty level information to the dictionary, normalizing the difficulty level information and adding a word with an appropriate difficulty level information to the original dictionary it can.

  Further, in the information processing apparatus according to the second invention, the first difficulty level information and the second difficulty level information are numerical values in a predetermined range, and The difficulty level information calculation unit converts the scale according to a predetermined calculation formula with respect to the one or more second difficulty level information acquired by the first acquisition unit and the one or more first difficulty level information acquired by the first acquisition unit. The first scale conversion means for acquiring one or more sets of coordinate information (X, Y) and the one or more second difficulty information acquired by the second acquisition unit are scale-converted by a predetermined calculation formula. Then, a linear regression analysis is performed on the second scale conversion unit that acquires one or more Y values of the coordinate information (X, Y) and one or more sets of coordinate information acquired by the first scale conversion unit. , Linear calculation formula determining means for determining a linear calculation formula (Y = f (X)) X value calculation means for substituting one or more Y values acquired by the second scale conversion means into the linear calculation formula and calculating one or more X values, and the X value calculation means, The calculated one or more X values are respectively substituted into the inverse function of the predetermined calculation formula, the one or more X values are scaled, the scale is restored, and the one or more first difficulty information It is an information processing apparatus which comprises the 1st difficulty information acquisition means which acquires.

  With this configuration, when adding a word with information on the difficulty level to the dictionary, the information on the difficulty level is normalized with high accuracy, and the word with the information on the appropriate difficulty level is added to the original dictionary. be able to.

  Further, the information processing apparatus according to the third aspect of the present invention stores two or more previous-stage first word difficulty information consisting of a set of word information and first difficulty information for either the first or second invention. A previous stage first word difficulty level information storage section, an inserted word information storage section storing one or more word information different from the word information included in the previous stage first word difficulty level information, and the previous stage number A word information acquisition unit that acquires a predetermined number of word information from one word difficulty level information and one or more word information from the inserted word information storage unit, and one or more word information acquired by the word information acquisition unit Based on the test word information output unit that outputs the above problem information, the reception unit that receives an answer from one or more users, and the one or more answers that the reception unit receives Each word information that each question information has A second difficulty level information calculation unit that calculates second difficulty level information for the second difficulty level information, and second difficulty level information calculated by the second difficulty level information calculation unit, the word information included in the previous-stage first word difficulty level information The second difficulty level information storage unit that stores the second difficulty level information corresponding to the second difficulty level information in the first word difficulty level information storage unit as the second difficulty level information included in the first word difficulty level information, 2nd difficulty level information which is the 2nd difficulty level information which the 2nd difficulty level information calculation part calculated and which is the 2nd difficulty level information corresponding to the word information which the said insertion word information storage part has The information processing apparatus further includes a second second difficulty level information storage unit that stores information in the second word difficulty level information storage unit.

(Embodiment 1)

  In the present embodiment, the information processing apparatus determines information related to test results for calculating the first word difficulty level (first word difficulty level information described later) and second word difficulty levels. Information about the test result for calculation (second word difficulty level information described later) is held in advance. It should be noted that the first test and the second test need only have different conditions. The conditions are the subject performing the test, the time when the test is performed, the venue where the test is performed, and the like. However, at least some of the words that are given in the first exam need to be given in the second exam. And this information processing apparatus normalizes the information regarding a difficulty, adds the information regarding a suitable difficulty to the word of the 2nd test object, and makes it the dictionary constructed | assembled by the 1st test. Perform additional processing.

  FIG. 1 is a block diagram of an information processing apparatus according to this embodiment.

  The information processing apparatus includes a reception unit 101, a first word difficulty level information storage unit 102, a second word difficulty level information storage unit 103, a first acquisition unit 104, a second acquisition unit 105, a first difficulty level information calculation unit 106, A first difficulty level information storage unit 107 and an output unit 108 are provided.

  The first difficulty level information calculation unit 106 includes a first scale conversion unit 1061, a second scale conversion unit 1062, a linear calculation formula determination unit 1063, an X value calculation unit 1064, and a first difficulty level information acquisition unit 1065.

  The accepting unit 101 accepts various instructions from the user. The instruction is, for example, a dictionary construction instruction for calculating first difficulty information and constructing a dictionary composed of a large number of word information having normalized first difficulty information. The instruction is, for example, an output instruction for outputting the constructed dictionary. The accepting unit 101 may accept other input from the user. The input means such as various instructions may be anything such as a keyboard, mouse or menu screen. The receiving unit 101 can be realized by a device driver for input means such as a keyboard, control software for a menu screen, or the like.

  The first word difficulty level information storage unit 102 stores two or more pieces of first word difficulty level information. Here, the first word difficulty level information is two types of information. The first has word information, first difficulty information, and second difficulty information. The second has word information and first difficulty information and does not have second difficulty information (information indicating that there is no second difficulty information may be used). Word information is word information. The word can be Japanese, English, Korean, Chinese, etc. The word includes a compound word. The first difficulty level information is information about the result of the evaluation related to the first difficulty level of the word. The evaluation regarding the first difficulty level is, for example, a test for calculating the difficulty level of the first word. That is, the evaluation regarding the first difficulty level is an evaluation performed when the evaluation regarding the second difficulty level is different (the evaluator may be different or the time may be different). The second difficulty level information is information about the result of the evaluation regarding the second difficulty level of the word. The evaluation relating to the second difficulty level is an evaluation performed when different from the evaluation relating to the first difficulty level. The first difficulty level information and the second difficulty level information are numerical values between 0 and 1, for example. The first difficulty level information and the second difficulty level information are, for example, accuracy rates of one or more evaluators with respect to the word. The test in this case is, for example, a test in which one Japanese word and two English words are output and a correct translation of the Japanese word is selected. The first difficulty level information and the second difficulty level information are, for example, probability values that the correct translation has been selected. The first word difficulty level information storage unit 102 is preferably a non-volatile recording medium, but can also be realized by a volatile recording medium. In the present specification, the difficulty level may be a degree of difficulty indicating ease, or may be a degree of familiarity such as knowing a word, and may be an evaluation value from this viewpoint. The evaluation value may be an infinite level value, for example, a 5-level evaluation value from 1 to 5. The set of pairs of word information and first difficulty information included in the first word difficulty information is a first word dictionary that can be configured by the first evaluation. The first word dictionary may be a set of word information sorted in order of difficulty or in order of ease. If the first word dictionary is a set of word information sorted in order of difficulty or in order of difficulty, the order of sorting is information indicating the difficulty level, even without the difficulty level information. Shall be captured.

  The second word difficulty level information storage unit 103 stores one or more pieces of second word difficulty level information that includes word information and second word difficulty level information but does not have first difficulty level information. The word information included in the second word difficulty level information is information on words to be inserted into the first word dictionary. The word information included in the second word difficulty level information is information on a word that did not appear in the first test, and information on a word that appears in the second test. The second word difficulty level information storage unit 103 is preferably a non-volatile recording medium, but can also be realized by a volatile recording medium. The second word difficulty level information storage unit 103 may be configured with the same database or the same file as the first word difficulty level information storage unit 102. In such a case, for example, word information common to the first word difficulty level information and the second word difficulty level information may not be redundantly stored but may be stored as one word information.

  The first acquisition unit 104 receives one or more pieces of information having the first difficulty information and the second difficulty information included in the first word difficulty information having the second difficulty information from the first word difficulty information storage unit 102. get. It is preferable that the first acquisition unit 104 acquires the first difficulty level information, the second difficulty level information, and the word information in pairs. In this case, the information having the first difficulty level information and the second difficulty level information is information including the first difficulty level information, the second difficulty level information, and the word information. Moreover, the 1st acquisition part 104 may acquire the information which consists of ID of 1st difficulty information, 2nd difficulty information, and 1st word difficulty information. In this case, the information having the first difficulty level information and the second difficulty level information is information including the IDs of the first difficulty level information, the second difficulty level information, and the first word difficulty level information. Moreover, the number of information which the 1st acquisition part 104 acquires does not ask | require. The first acquisition unit 104 acquires, for example, information having the first difficulty level information and the second difficulty level information by the number input by the user using an input unit such as a keyboard and the number indicated by the reception unit 101. Moreover, it is preferable that the 1st acquisition part 104 acquires 2 or more information which has 1st difficulty information and 2nd difficulty information so that 2nd difficulty information may be scattered. For example, when the second difficulty level information is (0.1, 0.2, 0.4, 0.6, 0.9) and the reception unit 101 receives a numerical value “3”, the first acquisition unit It is preferable that 104 acquires the second difficulty level information of (0.1, 0.4, 0.9), the corresponding three first difficulty level information, and the three word information. The first acquisition unit 104 can usually be realized by an MPU, a memory, or the like. The processing procedure of the first acquisition unit 104 is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The second acquisition unit 105 acquires one or more pieces of information having the second difficulty level information from the second word difficulty level information storage unit 103. The information having the second difficulty level information is, for example, word information and second difficulty level information. The information having the second difficulty level information is, for example, the ID of the second word difficulty level information and the second difficulty level information. Usually, the second acquisition unit 105 acquires information having all the second difficulty level information from the second word difficulty level information storage unit 103. However, the 2nd acquisition part 105 does not need to acquire the information which has all the 2nd difficulty level information. Word information corresponding to the second difficulty level information acquired by the second acquisition unit 105 is information of a word to be added to the first dictionary. The second acquisition unit 105 can usually be realized by an MPU, a memory, or the like. The processing procedure of the second acquisition unit 105 is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The first difficulty level information calculation unit 106 includes one or more first difficulty level information and second difficulty level information acquired by the first acquisition unit 104, and one or more second difficulty level information acquired by the second acquisition unit 105. Based on the above, the first difficulty level information of one or more word information corresponding to the second difficulty level information acquired by the second acquisition unit 105 is calculated. That is, the first difficulty level information calculation unit 106 calculates the first difficulty level information corresponding to the word information of the added word from the second test result (two or more second difficulty level information). The calculated first difficulty level information is the first difficulty level information estimated from the second difficulty level information of the corresponding word information. The first difficulty level information is estimated based on the first difficulty level information and the second difficulty level information corresponding to the word information subjected to both the first and second tests, and the word subjected to only the second test. Based on the second difficulty level information corresponding to the information, the first difficulty level information calculation unit 106 performs. An example of a specific algorithm by which the first difficulty level information calculation unit 106 calculates the first difficulty level information will be described later. The first difficulty level information calculation unit 106 can be usually realized by an MPU, a memory, or the like. The processing procedure of the first difficulty level information calculation unit 106 is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The first scale conversion means 1061 of the first difficulty level information calculation unit 106 has one or more first difficulty level information (referred to as “x”) acquired by the first acquisition unit 104 and acquired by the first acquisition unit 104. One or more second difficulty level information (“y”) is scale-converted by a predetermined calculation formula to acquire one or more sets of coordinate information (X, Y).

Here, an example of the predetermined calculation formula is Formula 1.

  “X” and “y” are numerical values in a predetermined range, for example, numerical values in the range of “0” to “1”. Further, the above formula 1 is a formula for converting the scale of the numerical value in the range of “0” to “1” from “−∞” to “+ ∞”. Note that the above-described predetermined calculation formula may be another calculation formula as long as the numerical value in the range of “0” to “1” is scale-converted from “−∞” to “+ ∞”. Further, the predetermined calculation formula described above may not be a formula for converting the numerical value in the range of “0” to “1” from “−∞” to “+ ∞”. For example, the above-described predetermined calculation formula may be a formula that converts the numerical value in the range of “0” to “1” from “−10000” to “+10000”. It is preferable that the predetermined calculation formula is a formula that converts the numerical value in the range of “0” to “1” from “−∞” to “+ ∞”. Here, the coordinate information is not information indicating a position, but may be regarded as two pairs of numerical values. In Equation 1, “ρ” is a positive constant. In Equation 1, the greater the value of “ρ”, the greater the degree of scaling.

  The second scale conversion means 1062 performs scale conversion on the one or more second difficulty level information acquired by the second acquisition unit 105 using a predetermined calculation formula, and converts the Y value in the coordinate information (X, Y). Get one or more. Here, the predetermined calculation formula is, for example, a formula for calculating the Y value of Formula 1. The predetermined calculation formula here is the same as the calculation formula by which the first scale conversion means 1061 acquires the Y value of the coordinate information (X, Y).

  The linear calculation formula determination unit 1063 performs linear regression analysis on one or more sets of coordinate information (X, Y) acquired by the first scale conversion unit 1061 to obtain a linear calculation formula (Y = f (X)). decide. The linear calculation formula determination means 1063 performs linear regression analysis according to the following formula 2.

Here, E is an average value for each axis, and α is given by Equation 3 below.

  Formula 3 is “covariance / X-axis dispersion”.

  The linear calculation formula determining means 1063 determines a linear calculation formula (Y = f (X)). Specifically, for example, “E (X)”, “E (Y)”, Get “α” of 3. Since linear regression analysis is a known technique, detailed description thereof is omitted.

The X value calculation means 1064 substitutes one or more Y values acquired by the second scale conversion means 1062 into a linear calculation formula to calculate one or more X values (X ₂ ). Specifically, the X value calculation means 1064 calculates an X value of 1 or more by the following mathematical formula 4.

The first difficulty level information acquisition unit 1065 substitutes one or more X values (X ₂ ) calculated by the X value calculation unit 1064 into an inverse function of a predetermined calculation formula (Formula 5 below). One or more X values (X ₂ ) are scale-converted, the scale is restored, and one or more first difficulty level information (x ₂ ) is acquired.

  The first scale conversion unit 1061, the second scale conversion unit 1062, the linear calculation formula determination unit 1063, the X value calculation unit 1064, and the first difficulty level information acquisition unit 1065 can be usually realized by an MPU, a memory, or the like. The processing procedure of the first scale conversion means 1061 and the like is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The first difficulty level information accumulation unit 107 accumulates one or more first difficulty level information calculated by the first difficulty level information calculation unit 106 as first difficulty level information of the corresponding word information. The first difficulty level information accumulation unit 107 is one or more first difficulty level information calculation units 106 calculated by the first difficulty level information calculation unit 106 as first difficulty level information for the second word difficulty level information included in the second word difficulty level information storage unit 103. Accumulate difficulty information. The first difficulty level information storage unit 107 may store the first difficulty level information in a recording medium in the information processing apparatus, or may store the first difficulty level information in an external device. The first difficulty level information accumulating unit 107 is a pair of the first difficulty level information and the same second word difficulty level information storage unit with the word information included in the second word difficulty level information of the second word difficulty level information storage unit 103. 103 may be accumulated. The first difficulty level information storage unit 107 can usually be realized by an MPU, a memory, or the like. The processing procedure of the first difficulty level information storage unit 107 is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The output unit 108 outputs the stored dictionary information to the display 344 or the like based on an output instruction from the user. The dictionary information is, for example, a set of word information sorted by the first difficulty level information. The dictionary information is, for example, information having many sets of first difficulty level information and word information. Here, the output is a concept including display on a display, printing on a printer, audio output, transmission to an external device, accumulation in a recording medium, and the like. The output unit 108 may or may not include an output device such as a display or a speaker. The output unit 108 can be realized by output device driver software, or output device driver software and an output device.

  Next, the operation of the information processing apparatus will be described using the flowcharts of FIGS.

  (Step S201) The reception unit 101 determines whether a dictionary construction instruction from the user has been received. If a dictionary construction instruction is accepted, the process proceeds to step S202, and if a dictionary construction instruction is not accepted, the process returns to step S201.

  (Step S202) Whether the first acquisition unit 104 includes the numerical value indicating the number of pieces of information (first word difficulty level information or information included in the first word difficulty level information) acquired in the dictionary construction instruction received in step S201 Judge whether or not. If a numerical value is included, go to step S203, and if not, go to step S204.

  (Step S203) The first acquisition unit 104 sets the numerical value included in the accepted dictionary construction instruction as the acquisition number (G). The setting is, for example, a process of substituting a numerical value for the variable “number of acquisitions”.

  (Step S204) The first acquisition unit 104 sets a default value stored in advance as the acquisition number (G).

  (Step S205) The first acquisition unit 104 performs a first acquisition process. The first acquisition process will be described using the flowchart of FIG.

  (Step S206) The second acquisition unit 105 performs a second acquisition process. The second acquisition process is a process of acquiring one or more pieces of information having the second difficulty level information from the second word difficulty level information storage unit 103. The second acquisition process is a process of reading all the second word difficulty level information from the second word difficulty level information storage unit 103, for example.

  (Step S207) The first difficulty level information calculation unit 106 performs a first difficulty level information calculation process. The first difficulty level information calculation process will be described with reference to the flowchart of FIG.

  (Step S208) The first difficulty level information accumulation unit 107 accumulates one or more first difficulty level information calculated in Step S207 as first difficulty level information of the corresponding word information. Then, the process ends.

  In the flowchart of FIG. 2, the processing order of step S205 and step S206 is not limited.

  Although not described in the flowchart of FIG. 2, it goes without saying that the constructed dictionary is output when the accepting unit 101 accepts an output instruction after constructing the dictionary. The constructed dictionary is a dictionary in which word information evaluated in the second test is inserted into the first dictionary, and is appropriately referred to as a second dictionary. Each of the word information may include first difficulty level information, or first difficulty level information and second difficulty level information.

  Next, the first acquisition process of step S205 of FIG. 2 will be described using the flowchart of FIG.

  (Step S301) The first acquisition unit 104 acquires the number of first word difficulty level information having second difficulty level information from the first word difficulty level information storage unit 102.

  (Step S302) The first acquisition unit 104 sorts all the first word difficulty information in the first word difficulty information storage unit 102 using the second difficulty information or the first difficulty information as a key. That is, the 1st acquisition part 104 rearranges 1st word difficulty level information in order of difficulty. In addition, when the 1st word difficulty level information sorted in the order of difficulty is stored in the 1st word difficulty level information storage part 102, the process in this step is unnecessary.

  (Step S303) The first acquisition unit 104 determines the interval between the first word difficulty information (or a part thereof) to be acquired from the number of first word difficulty information acquired in Step S301 and the acquisition number (G). (N) is determined. That is, for example, when the number of first word difficulty information acquired in step S301 is 100 and the number of acquisition (G) is 10, the first word difficulty information (or a part thereof) is acquired at 10 intervals. . Through this process, the first word difficulty level information (or a part thereof) in which the difficulty levels are dispersed can be acquired.

  (Step S304) The first acquisition unit 104 substitutes 1 for a counter i.

  (Step S305) The first acquisition unit 104 determines whether or not the i-th first word difficulty level information exists in the first word difficulty level information group sorted in step S302. If the i-th first word difficulty level information exists, the process goes to step S306, and if the i-th first word difficulty level information does not exist, the process returns to the upper function.

  (Step S306) The first acquisition unit 104 acquires and temporarily stores the i-th first word difficulty level information.

  (Step S307) The first acquisition unit 104 assigns “i + n” to the counter i, and returns to Step S305.

  In addition, although the example of the algorithm which acquires the 1st word difficulty level information in which the difficulty level was disperse | distributed was shown in the flowchart of FIG. 3, another algorithm may be sufficient. The first acquisition unit 104 may appropriately acquire a predetermined number of pieces of first word difficulty information by generating random numbers.

  Next, the first difficulty level information processing in step S207 of FIG. 2 will be described using the flowchart of FIG.

  (Step S401) The first scale conversion means 1061 performs scale conversion on one or more sets (x, y) acquired by the first acquisition unit 104 using a predetermined calculation formula, and one or more sets of coordinate information (X, Y). Y) is acquired. Note that “x” in one set of (x, y) is first difficulty level information of one word, and “y” is second difficulty level information of the same word. Further, the predetermined calculation formula is, for example, Formula 1.

  (Step S402) The linear calculation formula determination means 1063 performs linear regression analysis on one or more sets of coordinate information (X, Y) acquired by the first scale conversion means 1061 to obtain a linear calculation formula (Y = f ( X)) is determined. The linear calculation formula can be calculated using, for example, Formulas 2 and 3 above.

  (Step S403) The second scale conversion means 1062 substitutes 1 for the counter i.

  (Step S404) The second scale conversion means 1062 determines whether or not the i-th second difficulty level information exists among the one or more second difficulty level information acquired by the second acquisition unit 105. If the second difficulty level information exists, the process goes to step S405, and if the second difficulty level information does not exist, the process returns to the upper function.

  (Step S405) The second scale conversion means 1062 performs scale conversion on the i-th second difficulty level information, and acquires a Y value. The equation for scale conversion is, for example, an equation for calculating the Y value of Equation 1.

(Step S406) The X value calculation means 1064 substitutes the one or more Y values acquired in Step S405 as the Y value of the linear calculation formula determined in Step S402, and calculates an X value (X ₂ ).

(Step S407) The first difficulty level information acquisition unit 1065 substitutes the one or more X values (X ₂ ) calculated in Step S406 into an inverse function of the predetermined calculation formula (for example, Formula 5), and one or more The X value (X ₂ ) is scale-converted, the scale is restored, and 1 or more first difficulty level information (x ₂ ) is acquired.

  (Step S408) The first difficulty level information acquisition unit 1065 increments the counter i by 1, and returns to Step S404.

  Hereinafter, a specific operation of the information processing apparatus according to the present embodiment will be described. First, the concept of processing performed by the information processing apparatus will be described with reference to the processing conceptual diagram of FIG. Here, it is assumed that the word information is English word information, and the information processing apparatus constructs a dictionary in which English words are arranged in order of difficulty.

  First, a builder who builds an English word dictionary arranged in order of difficulty performs, for example, a first test on whether or not 20,000 English words are known to 1000 test subjects. Build a first dictionary with sorted words. The first dictionary is a table of the first evaluation in FIG. This table has 20000 records composed of pairs of “ID” and “word information”. It is assumed that the first test was performed on October 25, 2002, for example.

  Next, it is assumed that a test of 1100 English words including the word 100 presented in the first test (second test) is performed on 800 subjects on October 21, 2005. In the second test, the difficulty level of 1000 words that were not presented in the first test can be determined. And this information processing apparatus performs the process which inserts into the first dictionary 1000 words considered for the first time in the second test in consideration of the degree of difficulty. More specifically, the information processing apparatus includes difficulty level information (for example, accuracy rate) in the second test of 100 English words given in the first and second tests, and the second test. Based on the difficulty information (for example, the correct answer rate) obtained from the second test of the 1000 words that were presented for the first time in, the first difficulty information of the 1000 words that were presented for the first time in the second test is calculated. (Normalized) to obtain information that can sort 21,000 English words in the order of difficulty according to the same criteria. That is, this information processing apparatus is a dictionary construction apparatus with difficulty that can add words one after another to the word dictionary sorted in the order of difficulty. FIG. 5 is a diagram showing the concept of inserting the words presented in the second evaluation into the dictionary obtained in the first evaluation (test).

  Next, a specific operation of the information processing apparatus will be described.

  First, FIG. 6 shows a first word difficulty level information management table of the first word difficulty level information storage unit 102 of the information processing apparatus. FIG. 7 shows a second word difficulty level information management table of the second word difficulty level information storage unit 103.

  The first word difficulty level information management table is a first dictionary and stores one or more records having “ID”, “word information”, “first difficulty level information”, and “second difficulty level information”. “ID” is information for identifying a record and exists for record management in the table. Here, the “first difficulty level information” is information indicating the accuracy rate of the result of the first evaluation (test). Here, the “second difficulty level information” is information indicating the accuracy rate of the result of the second evaluation (test). In the first word difficulty level information management table, the “second difficulty level information” may be “NULL” (information does not exist). In FIG. 6, “NULL” is indicated by “−”. The second word difficulty level information management table stores one or more records having “ID”, “word information”, and “second difficulty level information”.

  The information processing apparatus calculates first difficulty information of each word information in the second word difficulty information management table, and sorts the first word difficulty information management table from the first difficulty information of each word information. Each piece of word information in the second word difficulty level information management table is inserted into a location (record number location) that holds the difficulty level in the word information group. Specific processing will be described below.

  First, it is assumed that a user (person on the side of the test) inputs a dictionary construction instruction including a numerical value “100”. Then, the reception unit 101 receives a dictionary construction instruction including a numerical value “100”.

  Next, the first acquisition unit 104 acquires the first word difficulty level information whose “second difficulty level information” is not NULL from the first word difficulty level information management table of FIG. 6. Here, the 1st acquisition part 104 searches 100 1st word difficulty level information so that a difficulty level may be disperse | distributed. Then, it is assumed that the first acquisition unit 104 has acquired 100 first word difficulty level information shown in FIG. An example of a method in which the first acquisition unit 104 acquires 100 first word difficulty level information so that the difficulty levels are dispersed is the method of the flowchart of FIG. 3.

  Next, the 2nd acquisition part 105 reads all the 2nd word difficulty level information of FIG.

  Next, the first difficulty level information calculation unit 106 performs first difficulty level information processing as follows.

  First, the first scale conversion means 1061 performs the following on one or more sets ((x, y)) of “first difficulty level information (x)” and “second difficulty level information (y)” in FIG. Scale conversion is performed using Equation 1 to obtain one or more sets of coordinate information (X, Y). Here, in Equation 1, “ρ” is set as a constant “10”. Then, the first scale conversion means 1061 acquires coordinate information (X, Y) shown in FIG.

  Next, the linear calculation formula determination unit 1063 performs linear regression analysis on one or more sets of coordinate information (X, Y) acquired by the first scale conversion unit 1061 to obtain a linear calculation formula (Y = f (X )) Is determined. The linear calculation formula determination unit 1063 obtains “Y = 1.1X−2.13” here.

  Next, the second scale conversion means 1062 performs scale conversion on the second difficulty level information (y) in FIG. 7 by the equation for calculating the Y value in Equation 1, obtains the Y value, and obtains the table in FIG. obtain.

Next, the X value calculation means 1064 substitutes one or more Y values in the table of FIG. 10 as the Y value of the linear calculation formula (Y = 1.1X−2.13), and the X value ( X ₂₎ is calculated.

Next, the first difficulty level information acquisition unit 1065 substitutes the X value (X ₂ ) of FIG. 11 for an inverse function (Formula 5) of a predetermined calculation formula, and scales one or more X values (X ₂ ). Convert, restore scale, and obtain first difficulty level information (x ₂ ). The first difficulty level information (x ₂ ) is shown in the table of FIG.

  Then, the first difficulty level information storage unit 107 stores the first difficulty level information in the table of FIG. 12 as the first difficulty level information of the corresponding word information.

  As a result, the information processing apparatus can obtain a word information dictionary having difficulty level information as shown in FIG. In addition, this information processing apparatus can obtain a second dictionary composed of word information groups sorted in the order of difficulty by sorting all word information using the first difficulty information as a key by sorting means (not shown). .

  As described above, according to the present embodiment, it is possible to add a word to which information about an appropriate difficulty level is added to the dictionary.

  In the present embodiment, the algorithm by which the first difficulty level information calculation unit calculates the first difficulty level information may be an algorithm or the like in the second embodiment to be described later.

  Further, according to the present embodiment, it goes without saying that the word information may be not only English words but also words in other languages.

  Furthermore, the processing in the present embodiment may be realized by software. Then, this software may be distributed by software download or the like. Further, this software may be recorded and distributed on a recording medium such as a CD-ROM. This also applies to other embodiments in this specification. Note that the software that implements the information processing apparatus according to the present embodiment is the following program. That is, this program stores the first difficulty level information and the second difficulty level included in the first word difficulty level information having the second difficulty level information from one or more first word difficulty level information stored in the computer. A first acquisition step of acquiring one or more pieces of information having information; a second acquisition step of acquiring one or more pieces of information having second difficulty level information from one or more stored second word difficulty level information; Acquired in the second acquisition step based on one or more first difficulty information and second difficulty information acquired in the first acquisition step and one or more second difficulty information acquired in the second acquisition step A first difficulty level information calculating step of calculating first difficulty level information of one or more word information corresponding to the second difficulty level information, and one or more first difficulty levels calculated in the first difficulty level information calculating step Corresponding to each information Program for executing a first difficulty level information storing step of storing as the first challenge level data of word information that is.

  In the program, the first difficulty level information and the second difficulty level information are numerical values in a predetermined range, and the first difficulty level information calculation step is acquired in the first acquisition step. One or more second difficulty level information and one or more first difficulty level information acquired in the first acquisition step are scale-converted by a predetermined calculation formula to acquire one or more sets of coordinate information (X, Y). The first scale conversion step and the one or more second difficulty level information acquired in the second acquisition step are scale-converted by a predetermined calculation formula, and the Y value in the coordinate information (X, Y) is changed. A second scale conversion step for acquiring one or more, a linear calculation formula determination step for performing linear regression analysis on the one or more sets of coordinate information acquired in the first scale conversion step, and determining a linear calculation formula; One or more Y values acquired in the second scale conversion step are substituted into the linear calculation formula to calculate one or more X values, and one or more calculated in the X value calculation step The first difficulty level in which each X value is substituted into the inverse function of the predetermined calculation formula, the one or more X values are scaled, the scale is restored, and one or more first difficulty level information is obtained. It is preferable to include an information acquisition step.

  Further, it can be said that the information processing apparatus is an apparatus that executes a word dictionary production method that performs the following processing. That is, in this production method, the first difficulty level information and the second difficulty level information included in the first word difficulty level information having the second difficulty level information from the stored one or more first word difficulty level information.

The word dictionary production method is a dictionary composed of a set of word information having information on the difficulty level of words.

Furthermore, the word dictionary produced by the information processing apparatus can be used in a machine translation device, a word test, or a device in Patent Documents 1 to 4 of the prior art.
(Embodiment 2)

  In the present embodiment, the information processing apparatus performs a second test on a large number of subjects, acquires second word difficulty level information from the test results, and accumulates the second word difficulty level information. Further, similarly to the processing in the first embodiment, the information processing apparatus normalizes the information on the difficulty level, and selects the word that is the second test target word and the information on the appropriate difficulty level added thereto. Then, a process of adding to the first dictionary constructed by the first test is performed. However, in the present embodiment, the algorithm for calculating the difficulty level (second difficulty level information) of the word to be inserted is different from that in the first embodiment.

  FIG. 14 is a block diagram of the information processing apparatus according to this embodiment.

  The information processing apparatus includes a reception unit 101, a first word difficulty level information storage unit 102, a second word difficulty level information storage unit 103, a first acquisition unit 104, a second acquisition unit 105, a first difficulty level information calculation unit 1406, First difficulty level information storage unit 107, output unit 108, previous stage first word difficulty level information storage unit 1401, insertion word information storage unit 1402, word information acquisition unit 1403, test word information output unit 1404, second difficulty level information A calculation unit 1405, a first second difficulty information storage unit 1407, and a second second difficulty information storage unit 1408 are provided.

  The accepting unit 101 accepts responses from one or more users in response to the output of each piece of problem information in addition to the operations in the first embodiment. Note that the problem information is information on problems related to words. The problem information is, for example, information having a Japanese word and two English words. In this case, one of the two English words is a translation of a Japanese word, and the subject determines whether the answer is correct or incorrect depending on whether the correct translation has been selected.

  The previous-stage first word difficulty level information storage unit 1401 stores two or more previous-stage first word difficulty level information including a set of word information and first difficulty level information. The first difficulty information included in the first-stage first word difficulty information is, for example, the result of the first word test, and is information on the difficulty of the word. The word information here is information of words that are given only in the first test and words that are given in the first and second tests. Moreover, it can be considered that the first-stage first word difficulty level information includes the first dictionary. The first-stage first word difficulty level information storage unit 1401 is preferably a non-volatile recording medium, but can also be realized by a volatile recording medium.

  The inserted word information storage unit 1402 stores one or more pieces of word information different from the word information included in the previous-stage first word difficulty level information. The word information here is information of words that are given only in the second test. The inserted word information storage unit 1402 is preferably a non-volatile recording medium, but can also be realized by a volatile recording medium.

  The word information acquisition unit 1403 acquires a predetermined number of pieces of word information from the previous-stage first word difficulty level information in the previous-stage first word difficulty level information storage unit 1401. The word information acquisition unit 1403 acquires one or more pieces of word information from the insertion word information storage unit 1402. The word information acquisition unit 1403 normally acquires word information corresponding to the first difficulty level information so that the values of the first difficulty level information included in the previous-stage first word difficulty level information are dispersed. Further, the word information acquisition unit 1403 normally acquires all the word information held by the insertion word information storage unit 1402, but may not be all the word information. The timing at which the word information acquisition unit 1403 acquires the word information does not matter, but usually the word information is acquired when the reception unit 101 receives an instruction (such as a test start instruction) from the user. A specific example of an algorithm in which the word information acquisition unit 1403 acquires the word information corresponding to the first difficulty level information so that the values of the first difficulty level information included in the previous-stage first word difficulty level information is dispersed is as follows: Although it is the process of the flowchart of FIG. 3, other algorithms may be used. The word information acquisition unit 1403 can usually be realized by an MPU, a memory, or the like. The processing procedure of the word information acquisition unit 1403 is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The test word information output unit 1404 outputs one or more pieces of problem information having one or more pieces of word information acquired by the word information acquisition 1403 unit. The test word information output unit 1404 outputs word information, for example, when the reception unit 101 receives a word output instruction (test start instruction). However, the timing at which the test word information output unit 1404 outputs the word information does not matter. Here, output is a concept including display on a display, printing on a printer, sound output, transmission to an external device, and the like. The test word information output unit 1404 may or may not include an output device such as a display or a speaker. The test word information output unit 1404 can be implemented by output device driver software, or output device driver software and an output device.

  The second difficulty level information calculation unit 1405 calculates second difficulty level information for each word information included in each problem information based on one or more answers received by the reception unit 101. For example, the second difficulty level information calculation unit 1405 performs the following processing. It is the answer information received by the receiving unit 101, and it is determined whether or not the received answer information is correct from the answer information for each word information from a plurality of users and the answer information stored in advance. Then, the correct answer rate is calculated for each word information from the number of correct answers and the number of incorrect answers. The correct answer rate for each word information is second difficulty level information corresponding to the word information. The second difficulty level information calculation unit 1405 can be usually realized by an MPU, a memory, or the like. The processing procedure of the second difficulty level information calculation unit 1405 is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The first difficulty level information calculation unit 1406 includes one or more first difficulty level information and second difficulty level information acquired by the first acquisition unit 104, and one or more second difficulty level information acquired by the second acquisition unit 105. Based on the above, the first difficulty level information of one or more word information corresponding to the second difficulty level information acquired by the second acquisition unit 105 is calculated. A specific algorithm by which the first difficulty level information calculation unit 1406 calculates the first difficulty level information will be described later. The first difficulty level information calculation unit 1406 can be usually realized by an MPU, a memory, or the like. The processing procedure of the first difficulty level information calculation unit 1406 is usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The first second difficulty level information accumulation unit 1407 is the second difficulty level information calculated by the second difficulty level information calculation unit 1405, and the second difficulty level corresponding to the word information included in the previous-stage first word difficulty level information. The information is stored in the first word difficulty level information storage unit 102 as second difficulty level information included in the first word difficulty level information. The first second difficulty level information storage unit 1407 can be normally realized by an MPU, a memory, or the like. The processing procedure of the first second difficulty level information storage unit 1407 is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The second second difficulty level information accumulating unit 1408 is the second difficulty level information calculated by the second difficulty level information calculating unit 1405, and the second difficulty level information corresponding to the word information of the inserted word information storage unit 1402 is stored. The second word difficulty level information is stored in the second word difficulty level information storage unit 103 as second difficulty level information included in the second word difficulty level information. The second second difficulty level information storage unit 1408 can be usually realized by an MPU, a memory, or the like. The processing procedure of the second second difficulty level information storage unit 1408 is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  Next, the operation of the information processing apparatus will be described with reference to the flowcharts of FIGS. First, referring to the flowchart of FIG. 15, the information processing apparatus performs a second test, obtains an answer from one subject, acquires correct answer and incorrect answer information for each problem, and accumulates the information. explain. Note that, in the flowchart of FIG. 15, a process of answering one subject will be described.

  (Step S1501) The reception unit 101 determines whether an instruction to start the second test is received. If a start instruction is accepted, the process goes to step S1502, and if a start instruction is not accepted, the process returns to step S1501.

  (Step S1502) The word information acquisition unit 1403 acquires a predetermined number of pieces of word information from the previous-stage first word difficulty information in the previous-stage first word difficulty information storage unit 1401. It is preferable that the word information acquisition unit 1403 acquires word information corresponding to the first difficulty level information so that the values of the first difficulty level information are dispersed (so that the difficulty levels are dispersed).

  (Step S1503) The word information acquisition unit 1403 acquires all word information from the insertion word information storage unit 1402.

  (Step S1504) The test word information output unit 1404 substitutes 1 for the counter i.

  (Step S1505) The test word information output unit 1404 determines whether or not the i-th word information exists in the word information acquired in steps S1503 and S1504. If the i-th word information exists, the process goes to step S1506, and if the i-th word information does not exist, the process ends.

  (Step S1506) The test word information output unit 1404 constructs problem information using the i-th word information. For example, each word information (English word), word information similar to the word information, and a Japanese translation word of the word information are stored in pairs. Information, similar words of the i-th word information, and translated words may be read to form the problem information. A specific example of the problem information configuration method will be described later. However, the configuration method of the problem information does not matter.

  (Step S1507) The test word information output unit 1404 outputs the problem information configured in step S1506.

  (Step S1508) The reception unit 101 determines whether an answer has been received from the subject (user). If an answer is accepted, the process goes to step S1509, and if no answer is accepted, the process goes to step S1511.

  (Step S1509) The second difficulty level information calculation unit 1405 determines whether or not the answer received in step S1508 is correct. The second difficulty level information calculation unit 1405 holds, for example, correct answer information for the problem information, and combines the answer and correct answer information to determine whether the answer is correct. Since this process is a known technique, a detailed description is omitted. If the answer is correct, the process goes to step S1510. If the answer is not correct, the process goes to step S1512.

  (Step S1510) The second difficulty level information calculation unit 1405 substitutes information indicating “correct answer” into a variable indicating an answer. Then, the process goes to step S1513.

  (Step S1511) The second difficulty level information calculation unit 1405 determines whether or not a timeout has occurred. The time-out means that a time for accepting the user's answer has elapsed. If it is time-out, the process goes to step S1512. If it is not time-out, the process returns to step S1508.

  (Step S1512) The second difficulty level information calculation unit 1405 substitutes information indicating “incorrect answer” into a variable indicating an answer. Then, the process goes to step S1513.

  (Step S1513) The second difficulty level information calculation unit 1405 increments the counter i by one. Then, the process returns to step S1505.

  The information processing apparatus performs the processing described with reference to the flowchart of FIG. 15 for all subjects (for example, 1000 people), processes the responses of all subjects, and finally calculates the correct answer rate for each word information. . The correct answer rate for each word information is second difficulty level information for each word information. The first second difficulty level information accumulation unit 1407 is the second difficulty level information calculated by the second difficulty level information calculation unit 1405, and corresponds to the word information included in the previous-stage first word difficulty level information. The difficulty level information is accumulated in the first word difficulty level information storage unit 102 as second difficulty level information included in the first word difficulty level information. The second second difficulty level information accumulation unit 1408 is the second difficulty level information calculated by the second difficulty level information calculation unit 1405, and the second difficulty level corresponding to the word information included in the inserted word information storage unit 1402. Information is accumulated in the second word difficulty level information storage unit 103 as second difficulty level information included in the second word difficulty level information. In addition, since the process of calculating the correct answer rate in a state where correct / incorrect information for each word of all subjects is included is a known technique, description thereof is omitted.

  In the flowchart of FIG. 15, the order in which the problem information is output does not matter.

  Next, a process will be described in which the information processing apparatus receives word results of the second test and inserts word information into the first dictionary constructed by the first test. This process is the same as the flowchart of FIG. 2 except for the first difficulty level information calculation process in step S207. The first difficulty level information calculation process of the information processing apparatus will be described with reference to the flowchart of FIG.

  (Step S1601) The first difficulty level information calculation unit 1406 substitutes 1 for the counter i.

  (Step S1602) The first difficulty level information calculation unit 1406 determines whether or not the i-th word information exists. If the i-th word information exists, the process goes to step S1603. If the i-th word information does not exist, the process returns to the upper function. Note that the i-th word information is the word information (word information given only in the second test) that the inserted word information storage unit 1402 has, and the second second difficulty information storage unit 1408 has accumulated. This is word information paired with the second difficulty level information.

(Step S1603) The first difficulty level information calculation unit 1406 acquires second difficulty level information (y ₁ ) corresponding to the i-th word information. The second difficulty level information (y ₁ ) is the second difficulty level information accumulated by the second second difficulty level information accumulation unit 1408.

(Step S1604) The first difficulty level information calculation unit 1406 is larger than the second difficulty level information (y ₁ ) acquired in Step S1603 and has the second difficulty level closest to the second difficulty level information (y ₁ ). the information first difficulty information contained in the first word difficulty information having (y ₂₎ (x ₂₎ and the second difficulty information (y _2), read out from the first word difficulty information storage unit 102.

(Step S1605) The first difficulty level information calculation unit 1406 is smaller than the second difficulty level information (y ₁ ) acquired in Step S1603 and has the second difficulty level closest to the second difficulty level information (y ₁ ). the information first difficulty information contained in the first word difficulty information having (y ₃₎ (x ₃₎ and the second difficulty information (y _3), reads from the first word difficulty information storage unit 102.

Specifically, the first difficulty level information calculation unit 1406 includes second difficulty level information (y ₁ ), first difficulty level information (x ₂ ), second difficulty level information (y ₂ ), and first difficulty level information. First difficulty level information (x ₁ ) is calculated by a function having (x ₃ ) and second difficulty level information (y ₃ ) as parameters. More specifically, for example, the first difficulty level information calculation unit 1406 calculates the first difficulty level information (x ₁ ) by the following Expression 6. However, the first difficulty level information calculation unit 1406 may calculate the first difficulty level information (x ₁ ) using a calculation expression other than Expression 6.

  (Step S1607) The first difficulty level information calculation unit 1406 increments the counter i by one. Then, the process returns to step S1602.

  Hereinafter, a specific operation of the information processing apparatus according to the present embodiment will be described. FIG. 17 is a conceptual diagram of an information processing system having an information processing apparatus. 17, the information processing system includes an information processing device 171 according to the present embodiment and one or more information processing terminals 172... Of one or more subjects.

  The information processing apparatus 171 performs a word test on the information processing terminals 172 of a large number of subjects. It is assumed that the test performed here is the second test. As a result of the first test, first word difficulty level information (first dictionary) having word information and difficulty level information (first difficulty level information) of each word information is stored. Here, the stored first word difficulty level information is the previous-stage first word difficulty level information. A set of previous-stage first word difficulty information stored in the previous-stage first word difficulty information storage unit 1401 of the information processing apparatus 171 (previous-stage first word difficulty information management table) is, for example, FIG. 18.

  The inserted word information storage unit 1402 stores one or more pieces of word information for the first time in the second test. An example of an insertion word information management table managed by the insertion word information storage unit 1402 is shown in FIG.

  Furthermore, the information processing apparatus 171 uses a means (not shown) to process similar words (word information “clock”) of each word information (word information in the first-stage first word difficulty level information storage unit 1401 and the inserted word information storage unit 1402). "Time") and the translation of each word information ("clock" with respect to the word information "clock").

  In such a situation, the reception unit 101 of the information processing device 171 receives an instruction to start a test from the user, and the word information acquisition unit 1403 converts the word information to be tested into the first-stage first word difficulty level information storage unit 1401. And read from the inserted word information storage unit 1402.

  Then, the test word information output unit 1404 also reads a similar word (for example, “time”) of the word information (for example, “clock”) acquired by the word information acquisition unit 1403 and a translation (for example, “clock”).

  Next, the test word information output unit 1404 constitutes problem information. Then, the test word information output unit 1404 outputs the problem information to the information processing terminal 172 of the subject as shown in FIG.

  Next, the subject inputs an answer. The subject inputs “B”, for example.

  Next, the reception unit 101 of the information processing device 171 receives the answer “B” of the subject, and the second difficulty level information calculation unit 1405 determines that the answer is correct.

  By repeating this process for all the subjects and for all the word information, the information processing apparatus 171 can obtain correct / incorrect information for all the word information of all the subjects.

  Next, the second difficulty level information calculation unit 1405 calculates the correct answer rate for each word information from the correct / incorrect information of all the subjects for each word information. The correct answer rate is second difficulty level information.

  The first second difficulty level information accumulation unit 1407 is the second difficulty level information (here, the correct answer rate) calculated by the second difficulty level information calculation unit 1405, and is included in the previous-stage first word difficulty level information. The second difficulty level information (here, the correct answer rate) corresponding to the word information is accumulated in the first word difficulty level information storage unit 102 as the second difficulty level information included in the first word difficulty level information. The second second difficulty level information accumulation unit 1408 is the second difficulty level information (here, the correct answer rate) calculated by the second difficulty level information calculation unit 1405, and the word information that the insertion word information storage unit 1402 has. Is stored in the second word difficulty level information storage unit 103 as the second difficulty level information included in the second word difficulty level information.

  Through the above processing, the information processing apparatus 171 can acquire, for example, the first word difficulty level information management table of FIG. 6 and the second word difficulty level information management table of FIG.

  Next, for example, according to a user instruction, the first difficulty level information calculation unit 1406 calculates first difficulty level information corresponding to the word information included in the second word difficulty level information. The algorithm for calculating the first difficulty level information is as shown in the flowchart of FIG.

  Then, the information processing apparatus 171 obtains a table having first difficulty level information of each word information having a structure as shown in FIG.
