A user who receives the learning support service by the learning support system 1 executes the learning application 231 on the terminal device 20 and logs into the learning support system 1 . Login to the learning support system 1 is performed, for example, by an authentication process in which the user ID and password input by the user and transmitted from the terminal device 20 to the server 10 are compared with the user ID and password registered in advance in the server 10. done. A user who has logged into the learning support system 1 can execute various functions of the learning support service on the learning application 231 .

(word search)
One of the basic functions of the learning support service provided by the learning support system 1 is searching for words in an English-Japanese dictionary. By performing a predetermined operation on the learning application 231 , the user can display the dictionary screen 40 for searching words in the English-Japanese dictionary on the display unit 25 .

FIG. 8 is a diagram showing the dictionary screen 40. As shown in FIG.
The dictionary screen 40 includes a search box 41 for designating a word to be searched for, an item information display area 42 for displaying item information of the searched word, and an audio reproduction button 43 for reproducing the audio of the word. , a dictionary screen end button 44 for ending the word search, and the like are displayed. When a search is executed with the spelling of a word to be searched entered in the search box 41, the terminal device 20 acquires the item information of the word from the server 10, and displays the acquired item information in the item information display area 42. display. In addition, the server 10 registers the search date on which the word search was performed in the data block corresponding to the user who performed the search in the learning history DB 135 . As a result, the search history of words by the user is recorded.

The user can play back (output) the voice of the word displayed in the item information display area 42 by performing an operation to select the voice playback button 43 on the dictionary screen 40 . That is, when the voice reproduction button 43 is selected, the terminal device 20 acquires the voice data of the word from the server 10 and causes the voice output unit 26 to output the voice of the word using the voice data. In addition, the server 10 registers, in the learning history DB 135 , in the data block corresponding to the user who has performed the voice reproduction of the word, that the voice has been reproduced for the word. Thereby, the reproduction history of the voice of the word by the user is recorded.
As described above, in the learning support system 1, in addition to searching for words in various dictionaries, searching for words included in data related to books and documents, or searching for words included in data provided by Web services, etc. etc. is also possible. When these searches are performed, the word search history and voice playback history are also recorded.

(test)
In the learning support service provided by the learning support system 1, a language test can be conducted. By taking this test, the user can receive a determination of the learning level and establish the learning content. In this embodiment, a listening test and a reading test will be described as examples. In the listening test, for example, a question sentence is given by voice from the voice output unit 26, and an appropriate answer is given from a plurality of options included in the question sentence. Also, in the reading test, for example, a question sentence is displayed on the display unit 25 and given, and an appropriate answer is given from a plurality of options included in the question sentence. However, the content of the test is not limited to these.
The user can cause the display unit 25 to display a test screen 50 for performing a test by performing a predetermined operation on the learning application 231 .

FIG. 9 shows a test screen 50 for conducting a listening test.
On the test screen 50, there are a question sentence play button 51 for playing back the sound of the question sentence, an answer button 52 for answering the question, a hint request button 53 for requesting hint information, and hint information. A hint display area 54 to be displayed, a test end button 55 for ending the test, and the like are displayed. When the test screen 50 is displayed and the listening test is started, the terminal device 20 receives question sentence data from the server 10 . The question sentence data includes speech data and correct answer data of the question sentence. When the question includes an image, the question text data further includes image data of the image, and the image is displayed on the test screen 50 after the question text data is obtained.

When the question text playback button 51 is selected after the question text data has been received, the voice of the question text is played back (output from the voice output unit 26). In the example shown in FIG. 9, the speech of four sentences corresponding to the options A to D shown in the lower part of FIG. 9 is reproduced as question sentences. The user can answer the question by selecting the answer button 52 of the option considered correct (matching the content of the image) from among the plurality of answer buttons 52 based on the content of the question. When one of the answer buttons 52 is selected, the correct/wrong judgment result is displayed on the display unit 25 . Alternatively, after answers to a plurality of questions have been completed, the correct/wrong judgment results regarding the plurality of questions may be collectively displayed.

By selecting the hint request button 53 before selecting the answer button 52 after the voice of the question sentence is played, it is possible to request presentation of hint information related to the question. When the hint request button 53 is selected, first, a hint point selection screen 60 for selecting options for displaying hint information (hereinafter also referred to as "hint point") is displayed.

FIG. 10 is a diagram showing a hint location selection screen 60. As shown in FIG.
The hint location selection screen 60 displays a selection button 61 for specifying a hint location, a hint display button 62 for displaying hint information, and the like. When the hint display button 62 is selected in a state in which one of the options A to D is specified by selecting one of the selection buttons 61, the option (hint location) for presenting the hint information is determined, Hint information H (first hint information H1 or second hint information H2, which will be described later) is transmitted from the terminal device 20 to the server 10. A transmission request for hint data including "hint information H" is sent when pointing to one of the two. Upon receiving the hint data from the server 10, the terminal device 20 displays (presents) the hint information H on the test screen 50 (hint information presentation process).

11A and 11B are diagrams showing the test screen 50 on which the hint information H is displayed.
Here, a case where hint information H of option B is requested and displayed will be described as an example. In each test screen 50 of FIGS. 11A and 11B, hint information H related to the word “software”, which is one of the words forming the question sentence of option B, is displayed in the hint display area 54 . The displayed hint information H is selected by the server 10 and transmitted to the terminal device 20 . The hint information H is selected from the item information of the item “software” included in the dictionary DB 132 . Further, the hint information H having different contents is selected according to the search history of the word "software" by the user. In the listening test of this embodiment, according to the word search history, as shown in FIG. , the second hint information H2 including the spelling and translation of the word is displayed.
An operation related to selection of hint information H by the server 10 will be described below.

In response to the hint information presentation request, the server 10 selects hint information H to be presented to the user for each of the hint target words among the plurality of words forming the hint portion specified in the question sentence. Execute hint information selection processing. Here, the hint target word is a word obtained by excluding words that are not suitable as words for presenting the hint information H from the plurality of words that constitute the hint part. Specifically, words with a low learning difficulty level that are learned in lower grades such as elementary school (in this embodiment, words for which the "learning difficulty level" in the dictionary DB 132 is less than "4"), numerals ("one", "two", etc.), pronouns ("you", "me", etc.), and proper nouns ("Mt. Fuji", etc.) are excluded as hint target words.
Note that the hint target word may be a word related to the word, such as a derivative word, instead of the word itself included in the question sentence. For example, when the word "inventor" is included in the question sentence, "invention", which is a derivative of the word, may be used as a hint target word. In addition, when a word included in a question sentence is a conjugated form of a word, the original form of the word may be used as a hint target word. Further, when a word included in a question sentence is the base form of a word, the conjugation of the word may be used as a hint target word. For example, if the question sentence includes a past tense or past participle form of a verb, the root form of that word may be used as a hint target word. Also, the hint target word is not limited to these, and may be any word that can serve as a hint for the user to answer the question. For example, hint target words may be selected from words other than words (including derived words and conjugations) included in the question sentence.

The server 10 selects hint information H to be presented to the user from the item information of the word in the dictionary DB 132 in the hint information selection process performed for each word that is a hint target word. Specifically, based on the search history of the word by the user in the learning history DB 135, the sufficiency status of a plurality of different search history conditions is determined, and depending on the determination result of the sufficiency status, the hint information H to be selected for the word is determined. Differentiate content.

Specifically, the first search history condition among the plurality of search history conditions is that the learning history DB 135 includes a history of searching for the word and a history of reproducing the voice of the word. This is a non-playback condition that is satisfied when the audio is not played (corresponding to the "first situation"). Whether or not the unsearched condition is satisfied is determined based on the data strings of “search date” and “sound reproduction” in the learning history DB 135 . For example, in the case of the test that the user with the user ID "U1234" is doing on September 1, 2021, in the data block with the user ID "U1234" in the learning history DB 135 shown in FIG. Since the "search date" is registered and the "audio playback" is "0" (unplayed), it is determined that the audio unplayback condition is satisfied.

If the voice non-playback condition is satisfied, it can be assumed that the user performing the test has searched for the word and can grasp the meaning from the notation of the word. On the other hand, since the voice of the word is not reproduced, it can be assumed that the word cannot be heard from the voice of the question sentence. Therefore, when the voice unplayback condition is satisfied, the server 10 selects the notation of the word as the hint information H (first hint information H1) of the word. Accordingly, for example, in the above test performed by the user ID "U1234", the notation of the word "software" is displayed in the hint display area 54 as the first hint information H1, as shown in FIG. 11A. be. If the notation of the word is presented as the first hint information H1, the user can identify the word that the user has not heard and associate it with the meaning of the word that has already been learned.

In addition, the second search history condition among the plurality of search history conditions is not satisfied when the learning history DB 135 does not contain the history of searching for the above word (corresponding to the “second situation”). It is a search condition. Whether or not the unsearched condition is satisfied is determined based on the data strings of “search date” and “sound reproduction” in the learning history DB 135 . For example, in the case of the test that the user with the user ID "U1235" is doing on July 15, 2021, in the data block with the user ID "U1235" in the learning history DB 135 shown in FIG. Since "search date" is not registered and "voice reproduction" is "0" (not reproduced), it is determined that the unsearched condition is satisfied.

If the unsearched condition is satisfied, it can be inferred that the user has not learned the meaning of the word because the user has not searched for the word. In addition, since the sound of the word is not reproduced, it can be estimated that the word cannot be heard from the sound of the question sentence. Therefore, when the unsearched condition is satisfied, the server 10 selects the notation and translation of the word as hint information H (second hint information H2) of the word. Accordingly, for example, in the above test performed by the user ID "U1235", the notation and translation of the word "software" are displayed in the hint display area 54 as the second hint information H2, as shown in FIG. Is displayed. The notation of the word is presented as the second hint information H2, so that the user can specify the word that he/she could not catch, and from the translation of the hint information H, the user can grasp the meaning of the word.

In the listening test of the present embodiment, a word whose search history is included in the learning history DB 135 and whose history of reproducing the voice of the word is included in the learning history DB 135 is evaluated by the user's proficiency. Hint information is not displayed because it is a word with a high degree.

When the server 10 selects the hint information H by performing the hint information selection process for each word (hint target word) included in the hint part, the server 10 selects a predetermined number of words for which the hint information H is to be displayed on the test screen 50. . The number of words selected here is determined according to the “number of listening hint presentations” in the user management DB 134 . A method of selecting words for which hint information H is to be displayed is not particularly limited. For example, a method of selecting words in descending order of difficulty may be used. That is, when the "number of listening hint presentations" is "1", the word with the highest degree of difficulty is selected from a plurality of hint target words included in the hint part, and the hint information H of the word is displayed in the terminal device 20. and displayed on the test screen 50 . Further, when the "number of listening hints presented" is "2" or more, the hint information H of the corresponding number of words selected in descending order of difficulty is transmitted to the terminal device 20, and the list is displayed on the test screen 50. , or sequentially. Further, when the "number of listening hint presentations" is "all", the hint information H of all the hint target words included in the hint part is transmitted to the terminal device 20, and displayed on the test screen 50 in a list or in order. Is displayed.

Next, the presentation operation of the hint information H in the reading test will be described.
FIG. 12A is a diagram showing a test screen 80 for taking a reading test.
On the test screen 80, a question text display area 81 for displaying a question text, an answer button 82 for answering the question, a hint request button 83 for requesting hint information H, and hint information H are displayed. A hint display area 84 to be displayed, a test end button 85 for ending the test, and the like are displayed. The functions of the answer button 82, the hint request button 83, the hint display area 84, and the test end button 85 are the same as those of the answer button 52, the hint request button 53, the hint display area 54, and the test end button 55 described above.

When the test screen 80 is displayed and the reading test is started, the terminal device 20 receives question sentence data from the server 10 . The question sentence data includes text data of the question sentence and correct answer data. When the question includes an image, the question text data further includes image data of the image, and the image is displayed on the test screen 80 after the question text data is acquired.

When the question text data is completely received, the text of the question text is displayed in the question text display area 81 of the test screen 80 . Here, a question is displayed in which an appropriate word is selected from options A to D as a word to fill in the blanks in the question sentence. The user can answer the question by selecting the answer button 82 of the option that is considered correct among the plurality of answer buttons 82 based on the contents of the question sentence. When one of the answer buttons 82 is selected, the correct/wrong judgment result is displayed on the display section 25 . Alternatively, after answering a plurality of questions, the correct/wrong judgment results regarding the plurality of questions may be collectively displayed.

By selecting the hint request button 83 before selecting the answer button 82 after the question text is displayed, it is possible to request the presentation of hint information related to the question. When the hint request button 83 is selected, a transmission request for hint data including the hint information H is sent from the terminal device 20 to the server 10 . Upon receiving the hint data from the server 10 , the terminal device 20 displays (presents) the hint information H in the hint display area 84 of the test screen 80 . In FIG. 12A, "unnecessarily" is selected as a word for which hint information H is to be presented from among a plurality of words constituting a question sentence excluding options A to D, and the second hint information H2 of this word is is displayed.

Also in the reading test, the hint information H with different content is selected according to the user's search history of the word ("unnecessarily") for which the hint information H is presented. In the reading test of this embodiment, as shown in FIG. 12A, according to the search history, the second hint information H2 including the notation of the word "unnecessarily" in the English-Japanese dictionary and item information (here, translation) is displayed. There are cases where it is displayed and cases where the first hint information H1 including the notation of the word "unnecessarily" in the English-English dictionary and item information is displayed as shown in FIG. 12B. An operation related to selection of hint information H by the server 10 will be described below.

In the reading test, the first search history condition among the plurality of search history conditions described above is when the last time the word to be displayed in the hint information H was searched for is after the reference time (in the “first situation”). equivalent) is satisfied. In addition, the second search history condition among the plurality of search history conditions is when the last time the word to be displayed in the hint information H is searched is before the reference time (corresponding to the "second situation"). ) and when there is no search history for the word (corresponding to the “second situation”). The above-mentioned reference time can be set so that the length of the period from the reference time to the present time is within the range of the length of the period during which the memory of the learned content of the searched word is normally maintained, for example, 1 to 1 It may be about a month. The sufficiency of the first search time condition and the second search time condition is determined based on the “search date” data string of the learning history DB 135 .

If the first search time condition is satisfied among these, the user remembers the meaning of the word learned by searching for the word after the reference time, and the proficiency level related to the word is above a certain level. assumed to be height. Therefore, when the first search time condition is satisfied, the server 10 assigns the hint information H (first hint information H1) as the hint information H (first hint information H1) having a high degree of readability (readability low), select item information in English-English dictionary.

On the other hand, if the second search time condition is satisfied, the user may have forgotten the meaning of the word learned by searching for the word before the reference time, or may It is assumed that you have not done so and have not learned the meaning of the word. Therefore, when the second search time condition is satisfied, the server 10 sets the hint information H (second hint information H2) as having a low degree of difficulty of reading (ease of reading) as shown in FIG. 12A. high), select the item information of the English-Japanese dictionary.

The English-Japanese dictionary and the English-English dictionary in the above are examples when the native language of the user who is testing is Japanese. If the user's native language is other than Japanese, a dictionary in which item information is written in the language of the user's native language may be used instead of the English-Japanese dictionary. A dictionary written in a language other than the native language of the user may be used.

Also, in the reading test, as in the listening test described above, the user may be allowed to specify hints. For example, as shown in FIG. 13, when the question "What is the software?" An option for which information H is presented may be identified as a hint location. FIG. 13 illustrates a case where the user selects option B by a tap operation or the like. By selecting the hint display button 86 in this state, the word for which the hint information H is to be displayed is selected from among the plurality of words forming the text of the option B, and the hint information related to the word is selected by the above-described method. H is displayed.

Note that the first search history condition and the second search history condition are not limited to the above. Assuming that the first search history condition is satisfied when the search history of the word to be displayed in the hint information H is in the first situation, the second search history condition is that the search history of the word is It can be any condition that is met if the context is a second context that indicates less proficiency in the item than the first context. Further, the second hint information H2 selected when the second search history condition is satisfied is higher than the first hint information H1 selected when the first search history condition is satisfied. Words can be arbitrarily selected from the item information so that the amount of information is increased or the readability is increased.

(Display hint history)
In the learning support service provided by the learning support system 1, the user performs a predetermined operation on the learning application 231 so that the word corresponding to the hint information H presented to the user in the past is displayed on the hint history screen 70. Can be displayed in a list.

FIG. 14 shows a hint history screen 70. As shown in FIG.
The hint history screen 70 displays a list of hint history words 71 corresponding to the hint information H presented in the past, a hint history screen end button 72 for closing the hint history screen 70, and the like. Each hint history word 71 displays the date when the hint information H related to the hint history word 71 was displayed. The hint history words 71 and dates displayed on the hint history screen 70 are specified based on the “hint display date” in the learning history DB 135 . By performing an operation to select the hint history word 71, it is possible to transition to the dictionary screen 40 (FIG. 8) including the item information of the word.

(Control procedure for word search processing)
Next, a control procedure of word search processing for displaying the dictionary screen 40 of FIG. 8 will be described.
FIG. 15 is a flow chart showing a control procedure for word search processing.
In FIG. 15, the word search processing executed by the CPU 21 of the terminal device 20 and the word search processing executed by the CPU 11 of the server 10 are shown together.

When the word search process is started, the CPU 21 of the terminal device 20 causes the display section 25 to display the dictionary screen 40 (step S101). At this stage, the item information display area 42 may be blank.

The CPU 21 determines whether or not the user has performed a word search operation, that is, whether or not the spelling of a word has been entered in the search box 41 and a search execution instruction has been accepted (step S102). When it is determined that a word search operation has been performed ("YES" in step S102), the CPU 21 requests word data of the specified word (data including item information of the word) from the server 10 (step S103). Here, the CPU 21 transmits a word data request signal to the server 10 .

Upon receiving the word data request signal, the CPU 11 of the server 10 refers to the dictionary DB 132 and transmits word data including item information of the designated word to the terminal device 20 (step S201). Further, the CPU 11 updates the word search history in the learning history DB 135 (step S202). Here, the CPU 11 registers the search date of the word to be searched in the data block corresponding to the logged-in user in the learning history DB 135 .

When receiving the word data, the CPU 21 of the terminal device 20 displays the item information of the word in the item information display area 42 of the dictionary screen 40 (step S104).

The CPU 21 determines whether or not an operation to select the voice reproduction button 43 has been performed (step S105), and if it is determined that the operation has been performed ("YES" in step S105), the voice data of the word is reproduced. A request is made to the server 10 (step S106). Here, the CPU 21 transmits a voice data request signal to the server 10 .

When the CPU 11 of the server 10 receives the voice data request signal, it refers to the "voice file path" in the dictionary DB 132, acquires the voice data of the designated word, and transmits it to the terminal device 20 (step S203). Further, the CPU 11 updates the reproduction history of the voice of the word in the learning history DB 135 (step S204). Here, the CPU 11 changes the item of “sound reproduction” of the search target word to “1” in the data block corresponding to the logged-in user in the learning history DB 135 .

When receiving the voice data of the word, the CPU 21 of the terminal device 20 reproduces the voice of the word (step S107). Here, the CPU 11 supplies audio data to the audio output unit 26 and causes the audio output unit 26 to output the audio of the word.

If step S107 has ended, if it is determined that word search operation has not been performed in step S102 ("NO" in step S102), or if operation to select the voice reproduction button 43 has not been performed in step S105 ("NO" in step S105), the CPU 21 determines whether or not an operation to select the dictionary screen end button 44 has been performed (step S108). When it is determined that the operation to select the dictionary screen end button 44 has not been performed ("NO" in step S108), the CPU 21 returns the process to step S102. When it is determined that the operation to select the dictionary screen end button 44 has been performed ("YES" in step S108), the CPU 21 closes the dictionary screen 40 (step S109) and terminates the word search processing.
Further, the CPU 11 of the server 10 terminates the word search process after the process of step S204 is completed.

(Test processing control procedure)
Next, a test processing control procedure for performing the test operation described above will be described. Here, an example of test processing when conducting a listening test will be described.
FIG. 16 is a flowchart showing a control procedure of test processing executed by the CPU 21 of the terminal device 20. As shown in FIG.

When the test process is started, the CPU 21 of the terminal device 20 displays the test screen 50 on the display section 25 (step S301). In addition, the CPU 21 requests question text data from the server 10 and receives the question text data (step S302).

The CPU 21 determines whether or not an operation to select the question sentence playback button 51 has been performed (step S303). When it is determined that the operation has been performed ("YES" in step S303), the CPU 21 (question setting means) reproduces the voice data of the question sentence and sets the question (step S304). Here, the CPU 21 supplies the audio data to the audio output unit 26 and causes the audio output unit 26 to output the audio of the question sentence.

The CPU 21 determines whether or not an operation to select the hint request button 53 has been performed (step S305). display (step S306). The CPU 21 determines whether or not an operation for selecting a hint location has been performed using the selection button 61 and the hint display button 62 (step S307). ”), and step S307 is executed again.

If it is determined that an operation to select a hint location has been performed ("YES" in step S307), the CPU 21 requests the server 10 for hint data including hint information H about the selected hint location. is received (step S308). Upon receiving the hint data, the CPU 21 (hint information presenting means) causes the hint information H to be displayed in the hint display area 54 of the test screen 50 (step S309). Further, the CPU 21 requests the server 10 to register the hint display history of the word for which the hint information H is displayed (step S310).

When the process of step S310 ends, or when it is determined in step S305 that the operation to select the hint request button has not been performed ("NO" in step S305), the CPU 21 performs the operation of selecting the answer button 52. is performed (step S311). If it is determined that the operation to select the answer button 52 has not been performed ("NO" in step S311), the CPU 21 returns the process to step S305. If it is determined that the operation to select the answer button 52 has been performed ("YES" in step S311), the CPU 21 refers to the correct answer data included in the question text data to determine whether the answer is correct or incorrect, and displays the result of the correct/wrong decision. is displayed (step S312).

When the process of step S312 ends, or when it is determined in step S303 that an operation to select the play question text button 51 has not been performed ("NO" in step S303), the CPU 21 presses the test end button 55. It is determined whether or not a selection operation has been performed (step S313). When the CPU 21 determines that the operation to select the test end button 55 has not been performed (“NO” in step S313), the process returns to step S303, and when it is determined that the operation has been performed ( "YES" in step S313), the test screen 50 is closed (step S314), and the test processing is terminated.
Steps S308 and S309 in the test process of FIG. 16 correspond to "hint information presentation process".

FIG. 17 is a flow chart showing the control procedure of test processing executed by the CPU 11 of the server 10 .
The test processing on the side of the server 10 in FIG. 17 is executed in parallel with the test processing on the side of the terminal device 20 in FIG.

When the test process is started, the CPU 11 of the server 10 determines whether or not a transmission request for question text data has been received from the terminal device 20 (step S401). If it is determined that the question text data transmission request has not been received ("NO" in step S401), the CPU 11 executes step S401 again. If it is determined that a transmission request for question text data has been received ("YES" in step S401), the CPU 11 stores the data strings "audio file path", "image file path" and "correct answer" in the test DB 133. By referring to it, question sentence data including voice data, image data and correct answer data of the question sentence is transmitted to the terminal device 20 (step S402).

The CPU 11 (receiving means) determines whether or not a request for transmission of hint data has been received from the terminal device 20, that is, whether or not a request for presentation of hint information related to a question given to the user has been received (step S403). If it is determined that the hint data transmission request has not been received ("NO" in step S403), the CPU 11 executes step S403 again. ("YES" in step S403), a hint data generation process is executed (step S404).

FIG. 18 is a flow chart showing the control procedure of the hint data generation process.
When the hint data generation process is invoked, the CPU 11 refers to the data string of "text" in the test DB 133, and generates a list of multiple words forming hints from the text list of question sentences (step S501).

The CPU 11 substitutes "0" for the variable N (step S502), and determines whether or not the value of the variable N is less than the number of words in the word list generated at step S501 (step S503). When it is determined that the value of the variable N is less than the number of words in the word list (“YES” in step S503), the CPU 11 determines that the Nth word in the word list corresponds to the hint target word described above. It is determined whether or not to do so (step S504). Here, the CPU 11 refers to the "part of speech" and "familiarity difficulty" data strings in the dictionary DB 132, and refers to words to be excluded, such as numerals, proper nouns, and words whose proficiency difficulty is less than the threshold. If so, it is determined that the word does not correspond to the hint target word.

If it is determined that the Nth word corresponds to the hint target word ("YES" in step S504), the CPU 11 determines whether the Nth word has been searched for ( step S505). Here, the CPU 11 refers to the data block corresponding to the user who is performing the test in the learning history DB 135, and determines that the word has already been searched if the search date is registered for the word.

If it is determined that the Nth word is not a searched word ("NO" in step S505), the CPU 11 determines that the unsearched condition (second search history condition) is satisfied. , the notation and translation of the N-th word are selected as hint information H (second hint information H2) (step S506). Here, the CPU 11 refers to the item information of the N-th word in the dictionary DB 132, and acquires the notation and translation data of the word from the item information.

The CPU 11 determines whether or not the Nth word is a word with multiple meanings (step S509). For example, the word "bear" has two meanings: "bear" and "endure". Such words are registered in two items in the dictionary DB 132. Therefore, the CPU 11 detects words with multiple meanings when the words are registered in two or more items in the dictionary DB 132. It is determined that If the word is determined to have multiple meanings ("YES" in step S509), the CPU 11 reads the question based on the translation of the question registered in the "translation" data column of the test DB 133. An appropriate word translation is selected according to the translation of the sentence (step S510).

When step S510 ends, or when it is determined in step S509 that the word does not have multiple meanings (“NO” in step S509), the CPU 11 adds the selected hint information H to the hint data ( step S511).

On the other hand, if it is determined in step S505 that the N-th word is a searched word ("YES" in step S505), the CPU 11 determines that the N-th word is a word whose voice has already been reproduced. It is determined whether or not there is (step S507). Here, the CPU 11 refers to the data block corresponding to the user who is performing the test in the learning history DB 135, and if the data string of "sound reproduction" for the word is "1", the sound reproduction has been completed. is a word of

When it is determined that the N-th word is not a word whose voice has already been played back ("NO" in step S507), the CPU 11 determines that the voice unplayed condition (first search history condition) is satisfied. Then, only the notation of the Nth word is selected as hint information H (first hint information H1) (step S508). Here, the CPU 11 refers to the item information of the N-th word in the dictionary DB 132, and acquires the notation data of the word from the item information. After that, the CPU 11 shifts the process to step S511 and adds the selected hint information H to the hint data.

When it is determined that the Nth word is a word whose voice has been reproduced ("YES" in step S507), the CPU 11 considers that the word is highly proficient, and adds hint information H about the word. is not selected, and the flow proceeds to processing step S512. Step S512 is also executed when step S511 ends, or when it is determined in step S504 that the N-th word does not correspond to the hint target word ("NO" in step S504). In step S512, the CPU 11 substitutes "N+1" for the variable N, and shifts the process to step S503.

If it is determined in step S503 that the value of variable N is greater than or equal to the number of words in the word list ("NO" in step S503), CPU 11 selects the number of words according to the "number of listening hint presentations" in user management DB 134. is selected to generate hint data including the hint information H of the word (step S513). In other words, the CPU 11 adjusts the number of words included in the hint data (the number of pieces of hint information H) according to the “number of listening hint presentations” in the user management DB 134 .
When step S513 ends, the CPU 11 ends the hint data generation process and returns the process to the test process.
Steps S504, S505, and S507 in the hint data generation process of FIG. 18 are executed by the CPU 11 as acquisition means and determination means. Steps S506 and S508 to S511 are executed by the CPU 11 as determining means.

When the hint data generation process (step S404) in FIG. 17 ends, the CPU 11 transmits the generated hint data to the terminal device 20 (step S405).

In response to the hint display history registration request from the terminal device 20 (step S310 in FIG. 16), the CPU 11 registers the word for which the hint information H is displayed in the learning history DB 135 (step S406). Here, the CPU 11 registers the date when the hint was displayed in the “hint display date” in the learning history DB 135 .
When step S406 ends, the CPU 11 ends the test processing.

FIG. 19 is a flow chart showing the control procedure of hint data generation processing in the reading test.
When the reading test is being executed, the hint data generating process of FIG. 19 is executed instead of the hint data generating process of FIG. Steps S601 to S605 and S609 to S613 in the hint data generation process of FIG. 19 are the same as steps S501 to S505 and S509 to S513 in the hint data generation process of FIG.

In the hint data generation process of FIG. 19, if the CPU 11 determines in step S605 that the N-th word has been searched ("YES" in step S605), the CPU 11 It is determined whether or not the date and time are after the reference time (step S606). If it is determined that the search date and time is after the reference time ("YES" in step S606), the CPU 11 determines that the first search time condition (first search history condition) is satisfied, As hint information H (first hint information H1), the notation and item information of the Nth word in the English-English dictionary are selected (step S607). Here, the CPU 11 refers to the item information of the N-th word in the English-English dictionary in the dictionary DB 132, and acquires the notation of the word and data of the item information.

On the other hand, if it is determined in step S605 that the N-th word has not been searched ("NO" in step S605), or if the last time the word was searched in step S606 is before the reference time, If it is determined that there is ("NO" in step S606), the CPU 11 determines that the second search time condition (second search history condition) is satisfied, As hint information H2), the notation and translation of the Nth word in the English-Japanese dictionary are selected (step S608). Here, the CPU 11 refers to the item information of the N-th word in the English-Japanese dictionary in the dictionary DB 132, and acquires the notation and translation data of the word from the item information.
Subsequent processing is the same as the hint data generation processing in FIG.
Steps S604 to S606 in the hint data generation process of FIG. 19 are executed by the CPU 11 as acquisition means and determination means. Further, S507 to S611 are executed by the CPU 11 as determining means.

(Control procedure for hint history display processing)
Next, a control procedure of hint history display processing for performing a hint history display operation using the hint history screen 70 of FIG. 14 will be described.

FIG. 20 is a flow chart showing the control procedure of the hint history display process.
The hint history display process is executed by the CPU 11 as hint history presenting means. When the hint history display process is started, the CPU 21 of the terminal device 20 causes the display unit 25 to display the hint history screen 70 (step S701).

The CPU 21 acquires from the server 10 the hint history data related to the hint information H displayed in the past (step S702). Here, the server 10 transmits to the terminal device 20 hint history data including word data for which the “hint display date” is registered in the learning history DB 135 . When receiving the hint history data, the CPU 21 displays hint history words 71 on the hint history screen 70 (step S703).

The CPU 21 determines whether or not an operation to select the hint history word 71 has been performed (step S704). When it is determined that the operation has been performed ("YES" in step S704), the CPU 21 causes the display on the display unit 25 to transition to the dictionary screen 40 (step S705), and displays the selected word in the dictionary DB 132. Information is acquired from the server 10 (step S706), and item information of the selected word is displayed on the dictionary screen 40 (step S707).

The CPU 21 determines whether or not an operation to select the dictionary screen end button 44 has been performed (step S708), and if it is determined that the operation has not been performed (“NO” in step S708), step S708 is performed again. to run. When it is determined that the operation has been performed ("YES" in step S708), the CPU 21 closes the dictionary screen 40 (step S709) and terminates the hint history display process.

On the other hand, if it is determined in step S704 that an operation to select the hint history word 71 has not been performed ("NO" in step S704), the CPU 21 determines whether an operation to select the hint history screen end button 72 has been performed. It is determined whether or not (step S710). If the CPU 21 determines that the operation has not been performed ("NO" in step S710), it returns the process to step S704, and if it determines that the operation has been performed ("YES" in step S710), The CPU 21 closes the hint history screen 70 (step S711) and terminates the hint history display process.

<effect>
As described above, the server 10 as an information processing apparatus according to the present embodiment has the CPU 11, and the CPU 11 acquires search history information from the learning history DB 135 for words related to questions presented to the user ( Acquisition means), determines whether or not the search history condition is satisfied with respect to the search history information (determination means), and determines hint information H related to the problem to be presented to the user based on the determination result of the satisfaction status (determination means). means). As a result, it is possible to select and determine the hint information H having appropriate content according to the user's word search history. Therefore, it is possible to present the user with appropriate hint information H according to the user's proficiency level of the word. In addition, since the user can timely check required information (word notation and translation), the user can study efficiently.

In addition, the CPU 11 discriminates whether a plurality of different search history conditions are satisfied for the search history information (determining means), and one of the plurality of search history conditions is determined when the state of the word search history is the first state. and the other one of the plurality of search history conditions is a second search history condition indicating that the word's proficiency level is lower than that of the first condition. is a second search history condition that is satisfied when the first search history condition is satisfied, the CPU 11 as determining means selects the word If the first hint information H1 is selected from the item information related to the word, and the second search history condition is satisfied, the item information related to the word From among them, the second hint information H2 having a larger amount of information or having a higher readability than the first hint information H1 is selected. As a result, it is possible to present the user with hint information H having an appropriate amount of information according to the user's proficiency level of words, or hint information H having appropriate legibility.

In addition, the word to be displayed in the hint information H is any one of a plurality of words forming the question sentence, the question is given by the voice of the question sentence, and the first search history condition is the learning history DB 135. contains a history of searching for the word and does not contain a history of reproducing the sound of the word. It is an unretrieved condition that is satisfied when the history of searching for the word is not included, and the CPU 11 as a determining means selects the word as the first hint information H1 when the voice unreproduced condition is satisfied. is selected, and if the unretrieved condition is satisfied, the notation and translation of the word are selected as the second hint information H2.
If the voice unplayback condition is satisfied, it can be assumed that the user taking the test has already searched for the word and can grasp the meaning from the notation of the word. On the other hand, since the voice of the word is not reproduced, it can be assumed that the word cannot be heard from the voice of the question sentence. Therefore, by selecting the notation of a word as the hint information H when the voice non-playback condition is satisfied in the listening test, the user can identify the word that the user has not heard and associate it with the meaning of the word that has already been learned. be able to. Therefore, it is possible to present appropriate hint information H according to the user's proficiency level of words.
On the other hand, if the unsearched condition is satisfied, it can be assumed that the user has not learned the meaning of the word. In addition, since the sound of the word is not reproduced, it can be estimated that the word cannot be heard from the sound of the question sentence. Therefore, by selecting the notation and translation of the word as the hint information H when the unretrieved condition is satisfied in the listening test, the user can identify the word that the user could not catch from the notation of the word in the hint information H. Also, from the translation of a word in the hint information H, the meaning of the word can be grasped. Therefore, it is possible to present appropriate hint information H according to the user's proficiency level of words.
In addition, by presenting the notation of words as hint information H, it is possible to proceed with learning even when the words themselves in the question sentence in the listening test are unfamiliar and the spelling for searching the dictionary cannot be identified. Since it is possible to provide the user with the information (spelling) necessary for learning, the user's learning efficiency can be improved.

Also, the word to be displayed in the hint information H is any one of a plurality of words forming the question sentence of the question. is after the reference time, and the second search history condition is that the last time the word was searched before the reference time, and the search history This is the second search time condition that is satisfied when the information does not include a history of word searches. According to this, the hint information H having an appropriate amount of information corresponding to the length of the elapsed time (and whether or not there is a search history) since the last time the word was searched (learned), or the hint having an appropriate readability Information H can be presented to the user. In other words, if the time point at which a word was last searched for was before the reference time point (or if there is no search history), it is presumed that there is a possibility that the learned content of the word has been forgotten (or has not been learned). Thus, hint information H with a large amount of information or hint information H with high readability can be presented.

In addition, the CPU 11 as a determining means selects item information (items written in a language other than the native language of the user) of the English-English dictionary in the dictionary DB 132 when the first search time condition is satisfied in the reading test. information), and if the second search time condition is satisfied, the item information of the English-Japanese dictionary in the dictionary DB 132 (item information described in the native language of the user) is selected. ) to select the second hint information H2. In this way, when a short time has passed since the last word search (learning), the item information of the English-English dictionary with low legibility is presented as the hint information H. The first hint information H1 of the higher level can be presented, and the user can be urged to study additional English related to the contents of the English-English dictionary. In addition, if a long time has passed since the last time the word was searched (learned), or if the word has not been searched yet, item information of an English-Japanese dictionary with high legibility can be presented as hint information H. , the second hint information H2 of a level suitable for users with low proficiency can be presented.

In addition, the CPU 11 as a determining means selects, among a plurality of words, words whose mastery difficulty is equal to or higher than a predetermined lower limit difficulty (words whose mastery difficulty is equal to or higher than a threshold value in the above-described embodiment). , select a word for which hint information H is to be displayed. As a result, it is possible not to display hint information H at a level that is unnecessary for many users.

Further, the CPU 11 as a hint history presenting unit selects words corresponding to the hint information H presented to the user in the past based on the learning history DB 135 including the hint history information related to the presentation history of the hint information H to the user. present to the user. This allows the user to effectively review the words.

Moreover, the CPU 11 as a determining means may select a plurality of pieces of hint information H corresponding to a plurality of words related to the question. Thereby, an appropriate amount of hint information H can be provided to the user.
