Description

  The present invention relates to a word acquisition training system, and in particular, according to the learner's learning level and the purpose of learning and the use of the language, it is possible to learn from a single word a formula related to that word, read, listen, write The present invention relates to a word acquisition training system that can acquire many words effectively and efficiently by practicing the words in the sentences suitable for the learner, comprehensive training of four skills of the language to speak.

The ability to communicate by language is the ability to comprehend and express one's partner, and in other words, to communicate smoothly with one another using language.
In order to improve language communication skills, you need to memorize words as words, idioms, idioms, grammars (text structure and order), etc. of the language and store them as knowledge and use them in the actual communication. Both things need to be done.

  The smallest unit of verbal communication is the word. Also, a plurality of words are combined to form idiom and idioms. Then, they are arranged according to the grammar to complete the sentences.

  Therefore, in order to improve language communication skills, it is fundamentally required to be able to understand the words uttered from the other party as accurately as possible and to be able to express them using the correct words as much as possible. As the number of words that can be understood and understood and the number of words that can be expressed increase, the breadth and depth of communication increases.

In addition, learning with words suited to the learner's learning level and words suited to the purpose of learning and the use field of the language further enhances learning efficiency.
Furthermore, learning from a single word into a formula that comprehends its related words can increase the number of words effectively and efficiently.

It should be noted that the more the number of comprehensible words and the greater the number of expressible words, the greater the help in reading books and newspapers other than communication and in creating materials and documents.
On the other hand, verbal communication is generally said to be composed of four elements: "Reading", "Listening", "Writing" and "Speaking" .

  Therefore, in order to improve communication skills, it is fundamental to comprehensively develop these four skills: "Reading ability", "Listening ability", "Writing ability" and "Speaking ability". Is divided into two parts from the direction of movement of information, "input" and "output", the former is translated into comprehension and the latter into expressive power.

Organizing the above, learning a word is as follows (see FIG. 10).
[Input of information-training of understanding ability]
・ "Reading": You will be able to see and recognize words with your eyes and understand their meaning.
・ "Hearing": You will be able to hear and recognize words with your ear and understand their meaning.
[Output of information-training of expressive power]
・ "Writing": Correct words will be extracted from knowledge (memory) and written correctly.
・ "Speaking": Correct words are extracted from knowledge (memory) and can be correctly said (pronunciation, intonation, etc.).

  However, it is not only difficult to comprehensively acquire the above-mentioned ability by the conventional memorization learning using a word card or a word book, and the method of repeatedly reading, remembering, writing and remembering, Although it is possible to accumulate words as knowledge, it is by no means sufficient in terms of acquiring communication skills. That is, for example, in English, which many people are learning in the world, it can not be denied that the Japanese are one of the reasons why they are not good at speaking although they know grammar and words .

  In addition, many of the printed conventional word learning materials have a mechanism in which the learner proactively selects the words that the learner wants to learn, since the learner gives the learner a pre-selected word. Absent. In the dictionary, although the learner can search the word that the learner wants to know proactively, it does not have a mechanism to memorize the word as knowledge.

  For example, Patent Documents 1 to 6 disclose various word learning systems.

JP, 2016-115335, A JP, 2015-034993, A JP, 2012-128378, A JP 2012-022153 A JP, 2012-022151, A Unexamined-Japanese-Patent No. 2010-145433

  However, in the word learning system using the conventional information communication technology including the above-mentioned patent documents 1 to 6, the dictionary is digitized to be a simple word practice in it, a spelling practice and a memorization practice, etc. I have been practicing single functions.

  For this reason, there is no provision for the learner to proactively select the word that he / she wants to learn. In addition, there is no function to learn related words in a formula or to comprehensively learn four language skills (reading, listening, writing, speaking).

Furthermore, the function of selecting and downloading a sentence suitable for the learner by artificial intelligence (AI) from sentences accumulated in big data using cloud computing and practicing a word in the sentence is also possible. not exist.
That is, there is no point in disclosing or suggesting a learning method that is comprehensively provided with the above-mentioned functions and mainly aimed at word acquisition training.

  The present invention has been made in view of such conventional problems, and can learn from related terms from a single word according to the learning level of the learner, the purpose of learning and the use field of the language, Word acquisition training that can acquire many words effectively and efficiently by practicing the words in the sentences suitable for the learner by comprehensive training of the 4 skills of reading, listening, writing and speaking languages It aims to provide a system.

  Hereinafter, embodiments of the present invention will be described. The word acquisition training system according to the present invention is an integrated word acquisition training system for effectively and efficiently remembering and actually using as many words as possible in order to enhance verbal communication skills.・ It is a method).

The whole block diagram of the word acquisition training system which is an embodiment of the present invention is shown in FIG.
In FIG. 1, a management unit 3 for managing a word acquisition training system, a data storage unit 5 for storing words, related words, sentences, a dictionary, user use history and the like as training materials on an Internet 1; A center server 10 is connected which includes a data transmission / reception unit 9 which transmits / receives data to / from a local station via the communication channel. The center server 10 is connected to at least one information terminal device 20 via the Internet 1. The information terminal device 20 is configured to be downloaded with words for training which are contents from the center server 10 and software necessary for the word acquisition training.

  The data downloaded by the data transmission / reception unit 9 via the interface 21 is stored in the teaching material storage unit 25 of the information terminal device 20. A microphone 27 is built in or connected to the information terminal device 20, and a voice picked up by the microphone 27 is converted into a digital signal by a voice extraction unit 29 in the information terminal device 20. The speech extracted by the speech extraction unit 29 is converted into text as speech by the speech analysis unit 31. However, the voice analysis unit 31 may have a structure in which text as a speech is converted into voice by being input from the teaching material storage unit 25.

The teaching material data stored in the teaching material storage unit 25 is reproduced by the reproduction unit 33 and displayed by the display unit 35. In the evaluation unit 37, how much the speech extracted by the speech extraction unit 29 or the text converted by the speech analysis unit 31 matches or differs from the speech data or text stored in advance in the teaching material storage unit 25 It is determined if there are any.
As described above, the speech data as the model may be stored in the teaching material storage unit 25. However, the text as the model may be compared in the form of speech conversion in each evaluation.

  The operation unit 39 is adapted to perform various operations necessary for the operation of the word acquisition training system. Further, the evaluation unit 37 determines whether the information input by the learner by key operation of the keyboard 41 is the same as the data stored in the learning material storage unit 25. The keyboard 41 may be configured by software displayed on the display unit 35.

  The information terminal device 20 is an information terminal device that can be connected to the Internet, such as a wearable computer (glasses type etc.), a smartphone, a tablet computer, a PDA, a game machine, an electronic dictionary, a navigation terminal, a personal computer, a digital television, etc. Good.

  In this word acquisition training system, necessary functional blocks are provided on the center side except the display unit 35, the reproduction unit 33, the keyboard 41, the microphone 27, the voice extraction unit 29, and the data transmission / reception unit 23 to make a cloud system. It is possible. In this case, the user can operate or display the word learning training system from the information terminal device 20 via a browser or an application.

Next, an overview of a word acquisition training system according to an embodiment of the present invention will be described.
The present invention is composed of the following six elements, and it is an integrated word acquisition training system (in order to acquire as many words as possible effectively and efficiently and to use those words properly in actual communication) e-learning method).
(1) Train according to the learner's learning level and the purpose of learning and the use of the language.
(2) With one word as a core, training is conducted by spreading the word into a form in accordance with the variants, synonyms, technical terms, idioms etc (hereinafter referred to as "related terms") and antonyms.
(3) 4 skills in reading (cognizing with eyes), listening (hearing and recognizing with ears), writing (key input with correct letters and spelling), speaking (pronounce with correct pronunciation and intonation) Train comprehensively.
(4) Train using not only single words but sentences containing many words to be learned.
(5) Use information communication technology to realize the above (1) to (4).
(6) With regard to the above sentence (4), cloud computing, big data and artificial intelligence (AI) are used to provide learner's learning level and example sentences suitable for the purpose of learning and the use of the language Do.

This word acquisition training system ("e-learning method") is fundamentally different from conventional learning methods that use cards and notes to simply memorize the meaning and spelling of words and phrases.
This word acquisition training system ("e-learning method") is also useful for preparing for exams such as written tests, hearing tests and interview tests of foreign languages that require word skills, in addition to improving communication skills.

Next, the operation of the word acquisition training system according to the embodiment of the present invention will be described.
First, the learner activates the word learning training system using the information terminal device 20 and performs initial setting. That is, the learner designates in advance his / her learning level and the field to be learned in the word acquisition training system. At this time, as shown in the user table 100 of FIG. 2, the user ID is assigned to each learner's name, and the learning level and the field symbol designated here are registered. However, these can be changed by the learner at any time.

Then, each time the learner starts learning, the learner designates a learning target word from the following three methods.
(1) A word given by the present system in the system of the present word acquisition training system.
(2) The learner designates the word he / she wants to learn by himself (key input).
(3) Specify weak words (select from the "weak word list")

In the following, the learning contents will be specifically described taking an example of an English learning system in which the word of (1) is given in the mechanism of the present system.
When the learner starts learning English, first, learning of words is performed as a first step. The learning of this word is divided into learning of a single word and learning of an example sentence including this word.

First, a method of processing learning of a single word will be described.
As shown in the word difficulty level table 110 of FIG. 3, each word is assigned in advance a learning difficulty level and a field symbol. Then, the word code is extracted from the word difficulty level table 110 according to the learning level and the field symbol registered by the learner in the user table 100. For example, in the case of a learner of user ID 10000, the learning level is 2 and the field symbol "i" is registered.

  Therefore, in the learning of a single word, at least one word of the word code 123450 which is the word of the field symbol "i" is extracted from the word difficulty table 110 at the same learning difficulty 2 as the learner's learning level 2 and the information terminal device 20 are displayed on the display unit 35. Here, the learning level is obtained by quantifying the beginner to advanced levels according to the level. In addition, the field symbol is assigned based on the purpose of learning, daily life, travel, hobbies, occupation, academic, etc.

The structure of the related term table 120 is shown in FIG. The related word table 120 stores words, word codes assigned to the words, word meanings, part of speech, change words, related words, and antonyms.
For example, with respect to the word "beautiful", words are grouped into related word -1 between the end of the variation words such as "beautifully", "beautifulness", "beauty" and "beautify". . That is, word codes are grouped, and an association between the word and a related word accompanied by at least one trailing change is assigned by code.

  Further, in the related word -2, a word and its synonym are associated. For example, the word code 123450 is "beautiful", but "charming", "cute", "good-looking", "lovely" and "pretty" are registered as synonyms of the word of this word code 123450 together with the word code . Then, an association between the word of the word code 123450 and at least one synonym is assigned by a code.

  Similarly, in the related word table 120, an antonym is also registered. For example, "ugly" and "unsightly" are registered as antonyms of the word of the word code 123450 as an antonym of the word of the word code 123450 as an antonym of "beautiful" of the word code 123450. Then, an association between the word of the word code 123450 and at least one antonym is assigned by a code.

  In the processing of the present system, first, as described above, “beautiful”, which is a word of the word code 123450 extracted from the word difficulty level table 110 according to the learner's learning level and the field symbol, is the information terminal by the present system. It is displayed on the display unit 35 of the device 20, and the system asks the learner the meaning of the word. Here, the learner thinks of the meaning of the word. At this time, a plurality of words may be extracted from the word difficulty level table 110 and displayed on the display unit 35, and the learner may be allowed to select one of the words.

  Next, the learner who thinks of the answer clicks the “meaning display button” displayed on the display unit 35. At this time, the meaning of the word code 123450 is extracted from the related term table 120 and displayed on the display unit 35 of the information terminal device 20. The learner sees the displayed meaning and evaluates whether his understanding is correct.

Prepare multiple evaluation stages. For example, 1) I understand correctly. 2) I understand to some extent. 3) I do not understand much. 4) I did not understand, I did not understand at all.
For example, when the learner self-estimates 3) or 4), the learner registers it in a “not good word list” database (not shown) in the data storage unit 5 of the center server 10. It should be noted that a “weak word list” database may be created not on the center server 10 side but on the information terminal device 20 side (hereinafter, the same effect).

  Here, the data registered in the “not good word list” database is organized for each learner and analyzed by the calculation unit 39. Then, once a word is mistaken, it is repeatedly practiced over a period. The frequency of this repetition is initially short and takes longer to establish memory. That is, when the learner registers and trains in the “sufferable word list” and self-determines that the word has been acquired as a result, and the learner deletes it from the “sufferable word list”, for example, three days later, one week later, 2 After weeks and multiple times, the word is automatically presented to the learner to have it be imprinted. In this way, the memory is fixed in consideration of the forgetting curve.

In addition, words that a plurality of learners at the same learning level make a mistake are taken statistics by the operation unit 39, and are registered as words that are easy for the learner at this learning level to make mistakes. During learning, these erroneous words may be preferentially presented and learned.
Although the learner has described the meaning of the word in the form of a quiz, it is also useful to select the correct meaning of the word and register the correctness in the "sufferable word list" database.

Next, a training method for the learner to read aloud correctly will be described. Now, the display unit 35 of the information terminal device 20 extracts the learning target word extracted from the word difficulty table 110, for example, "beautiful" of the word code 123450 and the related word table 120, and the meaning of the word of this word code 123450 is Let it be displayed.
(1) The learner reads aloud the presented learning target word toward the microphone 27.
(2) The voice extracted by the voice extraction unit 29 through the microphone 27 is input to the evaluation unit 37, and the reaction speed, the pronunciation, the intonation, the reading speed, and the voice size are evaluated.
(3) The result evaluated by the evaluation unit 37 is displayed on the display unit 35 as a radar chart. This radar chart is evaluated, for example, according to the five-point method, for five types of response speed, pronunciation, intonation, reading speed, and voice size. The evaluation result is stored in the data storage unit 5 of the center server 10. In addition, you may make it preserve | save not the center server 10 side but the information terminal device 20 side (following, the same effect).
(4) Next, the system reproduces "beautiful" of the word code 123450, which is a learning target word, into an audio signal by the reproducing unit 33, and transmits it as an audio from a speaker (not shown).
(5) The learner who listens to the voice points the word to the microphone 27 and repeats.
(6) The system evaluates the reaction speed, the pronunciation, the intonation, the reading speed, and the voice size in the evaluation unit 37 again.
(7) The evaluation result is displayed superimposed on the radar chart of the first evaluation result.
(8) Repeat (4) to (7) until the system reaches the set level.
By showing the first evaluation result and the latest evaluation result coaxially on the radar chart, the learner can confirm the difference from the first, that is, the degree of progress at a glance.
(9) End the training when the system reaches the set level. Or, the learner self-terminates. The data storage unit 5 records the number of times of correct reading aloud or the fact of self-termination.

Next, the learner will explain how to write words correctly. Now, it is assumed that only the meaning “beautiful” of the word of the word code 123450 extracted from the related term table 120 is displayed on the display unit 35 of the information terminal device 20 and the word is not displayed.
(1) The present system reproduces "beautiful" of the word code 123450, which is a learning target word, into an audio signal by the reproducing unit 33, and transmits it as an audio from a speaker (not shown).
(2) The learner key-inputs spelling of the word using the keyboard 41 of the information terminal device 20.
(3) The arithmetic unit 39 of the present system determines whether the input spelling is correct or not. If the input is correct, the process ends. ⇒ Go to (6) (4) If the entered spelling is incorrect, display “Incorrect” on the screen. At this time, the correct spelling is displayed on the screen, and disappears from the screen after a predetermined time (several seconds). The learner re-keys the spelling.
(5) Repeat (1) to (4) until the learner can input correct spelling. The reason for causing the learner to input the spelling again with the correct spelling erased from the screen after a certain period of time is to learn in a state where the concentration of the learner is increased and the brain is activated (hereinafter the same effect).
(6) When it becomes possible to input correct spelling, end the learning training of this word alone. Or, the learner self-terminates. The data storage unit 5 records the number of times of correct input or the fact of self-termination.

Next, a learning method in an example sentence including a learning target word will be described.
(1) First, a method of selecting an example sentence including a training target word will be described. This system selects from the example sentence database 130 in FIG. 5 the number of example sentences corresponding to the learning level and the field of the learner designated in the user table 100 in FIG. On the display unit 35 of FIG. At this time, a word is extracted from the word difficulty table 110 according to the learning difficulty level and the field, and an example sentence belonging to the word is extracted. Then, for example, as in the word code “123450” “beautiful”, the example sentences corresponding to the learner's learning level and the field are selected by the number provided in advance by the system provider side. An example of the example sentence thus selected is shown in FIG. However, in each of the example sentences shown in FIG. 5, the difficulty level and the field may be set for each example sentence, and the example sentences may be selected according to the degree of difficulty and the field.
(2) The learner starts training in the order displayed by the system or in an example sentence specified by himself.
(3) If you want to skip this training or if this training is finished, press the "Go to another exercise" button.

Next, each process of example sentence learning including a learning target word will be described.
First, a learning method is to understand the meaning of an example sentence including a learning target word.
(1) The system displays the example sentences extracted from the example sentence database 130 as described above, and asks the learner the meaning of the example sentences. Here, the learner thinks of the meaning of the example sentence.
(2) The learner who thinks of the answer displays the meaning of the example sentence by clicking the “meaning display button”, and self-evaluates whether or not his understanding is correct. Prepare multiple evaluation stages. For example, 1) I understand correctly. 2) I understand to some extent. 3) I do not understand much. 4) I do not understand at all.
If the learner evaluates itself as 3) and 4), the learner registers it in the “not good example list” database in the data storage unit 5 of the center server 10. It should be noted that the “not good example list” database may be created not on the center server 10 side but on the information terminal device 20 side (hereinafter, the same effect).
Although the learner has described the meaning of the example sentence as described in the quiz example 1 and the quiz example 2 of FIG. It is also useful to register in the list of poor example sentence lists.

Next, a training method will be described in which the learner aloudly reads an example sentence that correctly includes the learning target word. Now, it is assumed that an English example sentence including a learning target word extracted from the example sentence database 130 is displayed on the display unit 35 of the information terminal device 20.
(1) The learner reads the presented example sentences aloud to the microphone 27.
(2) The voice extracted by the voice extraction unit 29 through the microphone 27 is input to the evaluation unit 37, and the reaction speed, the pronunciation, the intonation, the reading speed, and the voice size are evaluated.
(3) The result evaluated by the evaluation unit 37 is displayed on the display unit 35 as a radar chart. This radar chart is evaluated, for example, according to the five-point method, for five types of response speed, pronunciation, intonation, reading speed, and voice size. The evaluation result is stored in the data storage unit 5 of the center server 10. In addition, you may make it preserve | save not the center server 10 side but the information terminal device 20 side.
(4) Next, in the present system, for example, the reproducing unit 33 reproduces an example sentence including “beautiful” of the word code 123450 which is a learning target word into an audio signal, and transmits it as an audio from a speaker (not shown).
(5) The learner directs the example sentence to the microphone 27 and repeats.
(6) The system evaluates the reaction speed, the pronunciation, the intonation, the reading speed, and the voice size in the evaluation unit 37 again.
(7) The evaluation result is displayed superimposed on the radar chart of the first evaluation result.
(8) Repeat (4) to (7) until the system reaches the set level.
By showing the first evaluation result and the latest evaluation result coaxially on the radar chart, the learner can confirm the difference from the first, that is, the degree of progress at a glance.

  Next, a case where a learner designates a learning target word from the “favorable word list” when learning starts will be described. For each learner, a “weak word list” is prepared in the data storage unit 5 and the weak words of the learner are stored. The present system appropriately selects a learning target word from the “favorable word list” and presents it to the learner on the display unit 35 of the information terminal device 20. With regard to the selection of the learning target word, it is presented in consideration of the priority such as that at which the learner made a mistake at a high frequency or one of the wrong words that has passed since the previous learning.

In the present embodiment, it has been described that an example sentence including the designated word, a related word, and an antonym is prepared in the example sentence database 130 of FIG. You will be able to register sentences such as exam questions and qualification exams, or allow each learner to register sentences that are useful personally. Each sentence is extracted in the form of being searched in advance with the words registered in the word difficulty level table 110 of FIG. 3, and the difficulty level and the field symbol are added on the side of this system. The field symbol may be attached to each source material. In addition, the degree of difficulty may be set manually on the system side for each word or sentence example, but initially the uniform setting is made for each material in the source material and each chapter in this material, and the correct answer rate of the learner It may be made to change automatically by. For example, at first, the system sets the difficulty level to 3 for a certain word, but if 80% or more of all the learners make a mistake about this word, the level is automatically raised to 4. On the other hand, when 80% or more of all learners correct the word correctly, the degree of difficulty is automatically dropped to 2.
Then, each word or sentence example is automatically extracted by the present system from at least one source material so as to match the learning level and the field of each learner, and provided to each learner. At this time, the source may be specified. For the learner, it is possible to increase learning efficiency by focusing on learning in the area of interest according to the level of one's own learning.

  In addition, difficulty levels and fields are assigned to each word and example sentence. Therefore, by taking statistics beyond the frame of each learner, for example, learners of the same learning level in the same field prefer a word or example sentence to a new learner or a learner currently learning It can be used as a guide when presenting learning candidates and learning recommendations such as the degree of popularity or which word or example sentence is likely to be mistaken.

  Furthermore, the learning level is set by each learner as his / her own level and may be different when viewed objectively. Therefore, for example, the results of word learning and example sentence learning of all the learners are put together, and the deviation value of the learners at the same learning level is taken, and if it exceeds a certain level, this learner is used as the information terminal device 20. You may give up on the display unit 35 and ask whether you may raise the learning level. When the learner presses the OK button, the learning level is raised by one. On the other hand, when the level is below a certain level, the system may actively mix words and sentences with low difficulty to increase the learning motivation of the learner.

  In addition, at the time of learning of each word or example sentence, the learner of the same level as this learner in the same corner of the same field as this learner learns this word in the screen corner of the display unit 35 displaying each word or example by setting of the learner It is also possible to display the correctness rate of how many correct answers about learning.

  Further, in the present embodiment, as the method of setting the learning target word, it has been described that the learning target word is extracted according to the mechanism set by the present system side and given to the learner, but the word the learner wants to learn You may specify by yourself from 41.

  Furthermore, in the present embodiment, although it has been described that words and sentences matching the level of the learner are learned in the learning steps of each stage, words and sentences matching the field specified by the learner are selected and learned. You may

Furthermore, in the present embodiment, learning of each word in the first to third stages, related words, antonyms and examples of these sentences is described as learning in order, but the icon for proceeding to each learning is displayed on the display unit For example, by selecting one of the words displayed for the plurality of words displayed in the first step, the learner can operate the icon of his choice by pressing a button. It may be possible to jump directly to the learning of each of these example sentence learnings. By this, it is possible to advance to a favorite learning from a single word to an expression which makes it possible to increase the efficiency and effect of learning.
Moreover, although the English word, the example sentence, etc. were demonstrated in this embodiment, it is applicable similarly about another foreign language.
