DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic dictionary having a vocabulary learning function.

[0002]

2. Description of the Related Art In the field of electronic dictionaries, there has been an electronic dictionary having a function of allowing a user to select a level and learn vocabulary of the level. The user repeatedly answers questions that are randomly asked or questions that are asked from a certain level.

[0003]

However, in the conventional learning function of the electronic dictionary as described above, questions are randomly asked or questions are asked only from a certain level.
The conventional level was a classification method such as “junior high school level”, but this method is not always a good method. Some words are widely known at the university student level, and at the junior high school level. Some words were rarely used, so it was necessary to review the leveling of each word.

[0004] In the conventional question format, if the questions are randomly selected, the user cannot concentrate on the level he / she wants to learn, and if the questions are given only from a certain level, the user may have several levels. I couldn't judge my level unless I tried, and I couldn't learn effectively. Therefore, there is a need for a method of determining a level to be learned for each user and a method of determining the current level of the user.

[0005] In the conventional question format, the question and the level are constant even when used by different users. In this case, since effective learning cannot be performed for each user, a function capable of performing learning suitable for each user has been desired. Further, in a problem of selecting a correct answer from a plurality of options, if a candidate other than the correct answer can be easily determined to be incorrect, the remaining one is determined to be correct. In this case, the learning effect does not increase because the user does not really understand and select the correct answer. Therefore, it is easier to make mistakes for candidates other than the correct answer and make the problem itself difficult, and if you make a mistake, you can give a question format that allows you to understand why you made a mistake, and you can give a question with a hint function to further deepen your understanding Such a function was desired.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the conventional electronic dictionary having a learning function, and to make learning suitable and efficient for each user. In the following points. (1) To provide an electronic dictionary having a learning function of setting words assigned in order of frequency.

(2) To provide an electronic dictionary having a selection function so that a plurality of users can learn with different settings on a single device. (3) To provide an electronic dictionary having a function of performing a simulation test capable of quickly determining a user's level. (4) To provide an electronic dictionary having a learning function of performing a question suitable for the ability of the user. (5) To provide an electronic dictionary having a function to enhance the learning effect.

[0008]

In order to achieve the above object, an electronic dictionary with a vocabulary learning function according to the present invention is provided with a data storage means in which word data leveled in order of frequency is stored in advance, and is confusingly apt to be mistaken for a correct answer. Incorrect answer generation means for generating incorrect answers, hint means to help the user's answer and understanding, incorrect answer selection erasing means that only the answer is erased when an incorrect answer is selected, depending on the ability of the user Automatic pace changing means for changing the progress of the question, automatic difficulty changing means for changing the difficulty of the question depending on the ability of the user, level determining means for performing a simulation test to determine the level of the user, There is a plurality of setting storage means that allows a user to learn with different settings with one unit.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. In the embodiment, a learning function for performing a four-choice synonym quiz in which a synonym of a given word is selected from options and answered is described. FIG. 1 is a block diagram illustrating a hardware configuration according to an embodiment of the present invention. FIG.
1 is a plan view showing the appearance of an embodiment of the present invention.

In FIG. 1, an input device 101 constituting an input means is provided with side function keys 202 to 2 in FIG.
07. The input device 101 is a central processing unit 10
2 (hereinafter referred to as a CPU), the results of past quizzes of the user, the history of questions that have been asked in the past, and each set value are stored in the random access memory 1 connected to the CPU 102.
10 (hereinafter referred to as RAM). CPU102
Are connected to read-only memories 104 to 109 (hereinafter referred to as ROMs).
09 contains word level data (ROM 10) which is data independent of the program (ROM 104).
5), definition data (ROM 106), thesaurus data (ROM 107), rule data (ROM
108) and pace data (ROM 109) are stored. The CPU 102 operates according to the contents of the program. The word level data (ROM 105) has values of levels arranged in the order in which the level of the most frequent word is determined to be the lowest and the level of the least frequent word is determined to be the highest, by examining the frequency of the base word appearing in a book or the like. It is composed of word data. This word level data (ROM 105)
One level is given to each word, and the word and the level are paired. The definition data is composed of dictionary (definition) data of each word in the word level data. The thesaurus data is composed of data stored for each synonym group of each word in the word level data. The rule data is composed of rule data for deriving a confusing incorrect answer. The pace data is composed of data on the degree of progress of the questions (skip rate of the question). CPU1
02 is connected to a display device 103 constituting a display means. Search data in ROMs 105-109,
The problem calculated by U102 is displayed on the display device 103. The problem is selected and answered by the input device 101.

The incorrect answer generating means, the hint means, the incorrect answer selecting erasing means, the automatic pace changing means, the automatic difficulty changing means, the level discriminating means, and the plural setting storing means are provided by the CPU 10.
2 is realized. The CPU implements an incorrect answer generation unit by searching for word level data, thesaurus data, and rule data.

Further, the hint means is realized by searching the definition data. In addition, when an incorrect answer is selected, only the selected word is deleted from the display, thereby realizing an incorrect answer selection erasing means. Also, RAM
An automatic pace changing means is realized by searching the user's past quiz results and pace data stored in 110 and calculating the progress of the next quiz.

[0013] Further, by changing the difficulty based on the pace determined by the automatic pace changing means, the automatic difficulty changing means is realized. In addition, a problem of each level is extracted and set as a question, and the level of the user is determined from the result, thereby realizing a level determining unit. Further, a plurality of settings storing means is realized by storing each setting of a plurality of users in the RAM 110.

Next, the operation of the present invention will be described with reference to FIGS.
In this embodiment, the question word is determined, the correct answer and the incorrect answer are searched and displayed as a question, the user answers, and the quiz tendency thereafter changes from the result. FIG. 3 is a flowchart showing the flow of the operation of the incorrect answer search. FIG. 4 is a table of rules used in FIG. This rule is stored in advance as rule data (ROM 108). Hereinafter, the flowchart of FIG. 3 will be described.

Step 1 is calculated based on the preset levels and the results of the user's past quizzes stored in the RAM 110 to determine the next word to be questioned, and at the same time, thesaurus data (ROM 107). The correct word is also determined by selecting one word from the synonyms of the question word. Next, an incorrect word other than the correct word must be derived, but if it is the first search, a candidate search is performed from the table of FIG. 4 in the rule data (ROM 108) according to the first rule (401) (step 3). . Here, the rules will be described. The first rule (40 in FIG. 4)
1) is “1a”, which is the first of the question words.
Antonyms (anton) of words in 1st synonym group
ym). Similarly, the next rule (402) “r1a” is a rhyming of the question word (rhyming).
Means to search for an antonym of a word in the first synonym group of the first synonym group. Thus, each rule includes antonyms (a), easily mistaken words (c), homonyms (r), homonyms (h), synonyms (t), and first synonyms ( 1), second synonym group (2),
Third synonym group (3), phrasal words are divided into words (p1-p
3) It is composed of various combinations of words that have been made and words of the same part of speech at a level higher than the question word. If a candidate is found in step 4, it is determined in step 5 whether the required number of candidates has been found. Here, when all the candidates are obtained, the search is completed and the problem is displayed. Otherwise, the search is continued until all candidates are found.

FIG. 5 shows a display state of a question and a case where a hint is selected. When the D key 205 is pressed while the question is displayed (501), the definition of the question word stored in the definition data (ROM 106) can be referred to (502). Pressing the D key 205 again returns to the quiz.

FIG. 6 shows an operation when the user selects an incorrect answer in the course of answering. First, the B key 203 is pressed in a state where the question is displayed (601). At this time, in the case of an incorrect answer, the candidate for the B key disappears from the display device 201 (602). Similarly, if the answer is incorrect again, the candidate further disappears (603). Since the remaining two candidates in this state are correct and incorrect, after the next selection, the answer is displayed regardless of the correct answer or incorrect answer (60).
4).

Next, the automatic pace changing means will be described. The pace is the skip rate of the questions,
If the pace is high, skip some new issues and ask questions. On the other hand, when the pace is low, the number of new questions is reduced, and the questions set in the past stored in the RAM 110 are repeatedly set. Next, an embodiment of a method of calculating a pace will be described. The average score of past quizzes stored in the RAM 110 is calculated, the pace is determined based on the average score, and stored in the RAM 110. When the average score is 100 points, the pace is set to 20 (701), and when the average score is 80 points, the pace is set to 10 (70).
2) If the average score is less than 62 points, the pace is set to 1 (703). As described above, the average score of the quiz performed by the user in the past is calculated as needed, and the pace changes accordingly.

FIG. 7 shows the operation of skipping a problem at each pace. Average (704) is R
The average score of the past quiz results stored in AM 110, Pace (705) is the value of the pace calculated from Average (704), Difficulty (706) is Pace (705)
The difficulty level of the problem, which is determined by Skip rate (707) is P
Skip rate of problem determined by ace (705), Past
question rate (708) is the percentage of past questions asked in the next set of quizzes, New questionrate
(709) is the ratio of new questions to be set in the next set of quizzes. In this example, it is assumed that the number of questions in one set of quizzes is made up of 20 questions, and 40 words whose word levels stored in the word level data (ROM 105) are 1 to 40 will be described. The crosses indicate the numbers of the questions to be asked. When the pace is 20 (701), the skip rate is 50%, and the player skips one question and proceeds. As a result, 40 questions are advanced by 20 questions. When the pace is 10 (702), the skip rate is 0%, so that 20 questions can be advanced without skipping one question. If the pace is 1 (703),
Without skipping, 90% of the questions are set based on past questions stored in the RAM 110, and 10% are set with new questions, so that only 20 questions can be advanced by 2 questions.

Thus, according to the user's past average points,
If the score is high, skip the questions and proceed to the next level one after another. If the score is low, repeat the past questions. Next, the difficulty level will be described. The difficulty determines whether the level of the correct word in the question is raised or lowered. The difficulty level is determined by the pace. The higher the pace, the higher the difficulty level, and the lower the pace, the lower the difficulty level. In the example, the pace is 18-2
If it is 0, it is set to “Challenge”, and the correct word is selected from the level higher than the question word.
Is set to "Normal", and the correct word is selected from the lower level than the question word.

FIG. 8 shows a user's level judgment operation in a simulation test performed when a user performs a quiz for the first time. In this example, the highest level is 1600
It is set to 0. First, the whole intermediate level (801)
The mock test starts from. Here, a quiz of one set of 10 questions is performed. If the result is 80 points or more, the level is raised and the quiz is performed again (802). If the result is 80 points or less, the level is lowered and the quiz is performed again (803). If the result is 80 points or more, raise the level and perform the quiz again (804).
It is determined to be 1,000 (805), and the level of the user is determined. In this way, the higher the score, the higher the level,
If the score is low, a quiz of giving a question from a low level is performed several times, gradually approaching the level of the user, and finally determining the current level of the user.

FIG. 9 shows the operation of saving a plurality of settings. When "Log-in" is selected on the setting screen (901), a plurality of user names are displayed (902). Individual setting values can be stored in each of the plurality of users.

[0023]

As described above, the present invention provides a data storage means for storing word data leveled in order of frequency in advance, an incorrect answer generation means for generating a confusing incorrect answer which is easily mistaken for a correct answer, and a user Hint means to help the answer and understanding of the answer, an incorrect answer selection erasing means that only the answer is erased in the case of an incorrect answer, an automatic pace changing means in which the progress of the question changes depending on the ability of the user, a user Automatic difficulty changing means that the difficulty of the question changes according to the ability of the user, level discriminating means for performing a mock test and discriminating the level of the user, and multiple setting storing means that a plurality of users can learn with different settings by one unit Has the following effects.

The conventional level has been considered based on academic activities such as "junior high school level", but is not always a good classification method in actual daily life. For example, some words are commonly used and widely used even at the university student level, and some words are rarely used everyday even at the junior high school level. Thus, by assigning levels based on the frequency of words appearing in newspapers, books, and the like, and using the data, effective learning closely related to daily life can be performed.

In addition, in the conventional question using the learning function of the electronic dictionary, a candidate for an incorrect answer can be clearly discriminated, and a correct answer can be selected without understanding the correct answer. However, in the present invention, it is easy to mistake a candidate for an incorrect answer other than the correct answer as a correct answer,
Improving the learning effect can be achieved by making it impossible to get a correct answer without a good understanding.

In the conventional learning function of the electronic dictionary, the user merely answers questions and answers, but the user cannot understand well and the learning effect is not improved. However, in the present invention, the translation of the question word is displayed as a hint. With the function, the user can learn while understanding well, so that the scholastic ability can be improved efficiently. Further, in the present invention, when the user selects an incorrect answer, only the selected incorrect answer is deleted, and the user can think again and make a selection again. Because you can learn, you can improve your academic ability efficiently.

Also, in the conventional electronic dictionary learning function, the questions and levels were the same even when the user changed, but this was not efficient because learning suitable for each user could not be performed. In the present invention, questions, levels, progress, difficulty, and the like change according to the level and ability of each user, so that effective learning suitable for each user can be performed, so that academic achievement can be improved efficiently. Can be.

Although there is a device that can set the level even with the conventional electronic dictionary learning function, the user cannot determine his / her level and cannot determine his / her level unless he / she tries various levels many times. Did not. In the present invention,
Even if the user does not understand his or her own level when using it, his / her level can be quickly determined by performing a simulation test and determining the level, and learning can be started therefrom, so that learning can be started efficiently.

Further, in a conventional electronic dictionary with a learning function, a plurality of settings cannot be stored in a single electronic dictionary and a plurality of users cannot learn with different settings. Since the setting can be stored for each user, a plurality of users can learn with each setting. The effect of the present invention, which can make use of convenient and effective functions not found in the learning function of these conventional electronic dictionaries, is extremely large.
