[0039] Figure 5 shows examples of search history aggregated data stored in the search history aggregated data memory area 12e, where (A) shows a weekly searched English word ranking based on the search history of an English-Japanese dictionary corresponding to a range of users with a certain user attribute, and (B) shows an average search count ranking based on the same search history.

[0040] The forgetting characteristic data memory area 12f stores data indicating the optimal review timing from the previous learning timing, which is set based on human forgetting characteristics (for example, 1 day (2nd time) / 3 days (3rd time) / 10 days (4th time) / 30 days (5th time)... after the first time).

[0041] The important word data storage area 12g stores data on important words that the user should review (for example, words that frequently appear in exams such as junior high school entrance exams, high school entrance exams, university entrance exams, and certification exams).

[0042] In the working data storage area 12h, various data generated or acquired in response to the control of the operation of each part by the control unit 11 is temporarily stored as necessary.

[0043] In the learning support server 10 configured in this manner, the control unit 11 controls the operation of each part of the circuit in accordance with the instructions written in the server control program 12a, and the software and hardware operate in cooperation to realize various functions as described in the operation explanation below.

[0044] <Electronic circuit of communication terminal 20> FIG. 6 is a block diagram showing the configuration of an electronic circuit of the communication terminal 20. As shown in FIG.

[0045] The electronic circuit of the communication terminal 20 includes a control unit (CPU) 22, which is a computer, a memory unit 23, a recording medium reading unit 25, a communication unit (Wi-Fi (registered trademark) communication / mobile communication) 26, and a touch panel display unit 21.

[0046] The control unit 22 controls the operation of each part of the circuit in accordance with a communication terminal control program 23a and a dictionary application program (dictionary app) 23b stored in the memory unit 23, in response to an input signal corresponding to a user operation from the touch panel display unit 21, or a signal received by the communication unit 26 from a web server (including the learning support server 10) on the communication network N.

[0047] The communication terminal control program 23a and the dictionary application 23b may be pre-stored in the memory unit 23, or may be read from an external recording medium 24 such as a memory card via the recording medium reading unit 25 and stored in the memory unit 23, or may be downloaded from a Web server (in this case, a program server) on the communication network N and read and stored in the memory unit 23.

[0048] The dictionary application 23b includes a program for executing at least the above-mentioned functions (20a) to (20f).

[0049] In the storage unit 23, in addition to storage areas for the communication terminal control program 23a and the dictionary application 23b, a compilation target user setting data storage area 23c, a learning target narrowing down condition data storage area 23d, a working data storage area 23e, and the like are secured.

[0050] The tally target user setting data storage area 23c stores user attributes of tally targets that are set arbitrarily by the user to allow the learning assistance server 10 to tally phrase search rankings and average search frequency rankings for phrases based on the phrase search history of each user. The user attributes of the tally targets here are set arbitrarily by the user, separate from tally targets when "phrase (word) search" is performed and tally targets when "search history tally" is performed with a range of text including multiple phrases (words) as the study target.

[0051] FIG. 7 shows a tally target person setting screen GT displayed on the touch panel display unit 21 in accordance with the dictionary application 23b of the communication terminal 20. As shown in FIG.

[0052] The tally target setting screen GT is displayed by touching and specifying the "tally target setting" item (not shown) in the menu displayed on the touch panel display unit 21 in accordance with the dictionary application 23b, and in accordance with the displayed tally target setting screen GT, the tally target for a "phrase (word) search" and the tally target for a "search history tally" are selected and set from the tally target selection list TL which lists user attributes categorized by items such as grade, class, preferred school, and examination grade.

[0053] The number of subjects to be counted is not limited to one or more.

[0054] When performing "Search History Aggregation" on the aggregation target setting screen GT, the aggregation target setting area is displayed with attribute-specific marks (red) RE and (blue) BL, which can be used to distinguish different attributes by color, according to the attributes of the aggregation target that has been set.

[0055] In the learning subject narrowing condition data storage area 23d, learning subject narrowing conditions for narrowing down the words (phrases) to be learned from the range of text when "search history compilation" is performed are stored, which are arbitrarily set by the user.

[0056] FIG. 8 shows a learning subject narrowing condition setting screen GJ displayed on the touch panel display unit 21 in accordance with the dictionary application 23b of the communication terminal 20. As shown in FIG.

[0057] The learning subject narrowing down condition setting screen GJ is displayed by touching and specifying the “narrowing down condition setting” item (not shown) in the menu displayed on the touch panel display unit 21 in accordance with the dictionary application 23b, and the user selects and sets one of the narrowing down conditions from “top searched words,” “forgetting characteristics,” “important words,” or “no conditions” in accordance with the displayed learning subject narrowing down condition setting screen GJ.

[0058] "Top searched" is selected when narrowing down the words included in the text range to words that are frequently searched for in the search history and are difficult to remember, "forgetting characteristics" is selected when narrowing down the words included in the text range to words that are effective for review based on forgetting characteristics, and "important words" is selected when narrowing down the words included in the text range to important words that should be reviewed.

[0059] The number of conditions for setting the learning target narrowing condition is not limited to one or more.

[0060] In addition, the user attributes of the target persons to be counted, set by the user in accordance with the target persons to be counted setting screen GT, and the learning target narrowing down conditions, set by the user in accordance with the learning target narrowing down conditions setting screen GJ, may be stored in the user management data memory area 12c of the learning support server 10 in association with the user ID of the user who set the target persons to be counted and the learning target narrowing down conditions, without being stored in the communication terminal 20.

[0061] In the working data storage area 23e, various data generated or acquired in response to the control of the operation of each part by the control unit 22 is temporarily stored as necessary.

[0062] In the communication terminal 20 configured in this manner, the control unit 22 controls the operation of each part of the circuit in accordance with the instructions written in the communication terminal control program 23a and the dictionary application 23b, and the software and hardware operate in cooperation to realize various functions as described in the operation explanation below.

[0063] (Operation of the embodiment) Next, the operation of the learning support system 1 according to the embodiment will be described.

[0064] FIG. 9 is a flowchart showing terminal processing according to the dictionary application 23b of the communication terminal 20. As shown in FIG.

[0065] FIG. 10 is a flowchart showing the server process of the learning assistance server 10 executed in response to the terminal process of the communication terminal 20. As shown in FIG.

[0066] FIG. 11 is a diagram showing screen transitions of the text display screen GD in response to "phrase (word) search" in a state in which the dictionary application 23b of the communication terminal 20 is activated.

[0067] When the dictionary application 23b is launched on the communication terminal 20 (step T1 (Yes)), and data of the English text to be studied by the user is received, for example, from a web server on the communication network N (Internet), the control unit 22 generates a text display screen GD that expands the received English text data, as shown in FIG. 11, and displays it on the touch panel display unit 21.

[0068] In order to search the dictionary for words contained in the English text on the text display screen GD, when the user U touches (long presses) the word “various” to be searched for, as shown in FIG. 11, the control unit 22 distinguishably displays H the specified word “various” and displays a [Search] button SK in association with the word “various.”

[0069] When the [Search] button SK for the word "various" is touched to instruct "word search" (step T2 (Yes)), the control unit 22 obtains the attribute data of the person to be counted (e.g., a third-year high school student) when performing a "phrase (word) search" from the person to be counted setting data memory area 23c (step T3).

[0070] The control unit 22 transmits the user ID of the communication terminal 20, the search target word "various," and the attribute data of the person to be counted to the learning assistance server 10 (step T4).

[0071] When the learning support server 10 receives the user ID sent from the communication terminal 20, the search target word "various", and the attribute data of the person being counted (steps S1, S2 (Yes)), the control unit 11 searches for the received word "various" based on the English-Japanese dictionary stored in the dictionary database memory area 12b, and obtains explanatory information including a translation corresponding to the word "various" (step S3).

[0072] Then, based on the received attribute data of the person to be counted, the control unit 11 determines whether the search target word “various” is included in the top (within the top 10) of the search ranking (see Figure 5(A)) of the person to be counted (a third-year high school student) stored in the search history count data memory area 12e (step S4).

[0073] If the search target word "various" is included in the top search rankings of the target person (a high school senior) (step S4 (Yes)), the control unit 11 sets a top search ranking flag (step S5).

[0074] Furthermore, the control unit 11 determines whether the search target word "various" is included in the top five (within the top five) of the average search frequency ranking (see FIG. 5(B)) of the subjects (third-year high school students) (step S6).

[0075] If the searched word "various" is included in the top search rankings of the person being tabulated (a third-year high school student) but is not included in the top (within the top five) of the average search frequency rankings (step S6 (No)), the control unit 11 transmits search result data including the top search ranking flag set in step S5 and explanatory information for the word "various" searched through the dictionary to the communication terminal 20 corresponding to the user ID received in step S1 (step S8).

[0076] When the communication terminal 20 receives search result data including the top search ranking flag sent from the learning support server 10 (steps T5, T6 (Yes)), the control unit 22 highlights the message “Other users are also looking for this” M1 at the bottom of the text display screen GD, as shown in FIG. 11, informing users that the dictionary-searched word “various” has a high search ranking (step T7), and displays the search result window W including explanatory information for the word “various” such as “Various, …” (step T10).

[0077] This allows users to easily confirm, right after searching the dictionary, that the word "various" that they are studying has also been widely researched and studied by a third-year high school student who is a rival for the university entrance exam, as specified by the user.

[0078] Furthermore, in the learning support server 10, if the searched word "various" is included in the top search rankings of the person being counted (a third-year high school student) (step S4 (Yes)) and is also included in the top average search count rankings (step S6 (Yes)), the control unit 11 sets a top average search count ranking flag in addition to the top search ranking flag set in step S5 (step S7), and transmits search result data including the set top search ranking flag and top average search count ranking flag, as well as explanatory information for the dictionary-searched word "various" to the communication terminal 20 corresponding to the user ID received in step S1 (step S8).

[0079] When the communication terminal 20 receives the search result data including the top search ranking flag and the top average search count ranking flag sent from the learning support server 10 (steps T5 to T8 (Yes)), the control unit 22 highlights a message M1 "Other users are also looking for this" notifying that the dictionary searched word "various" has a high search ranking at the bottom of the text display screen GD as shown in Fig. 11, and also highlights a message M2 "This word is difficult for other users to remember" notifying that the average search count ranking is high (step T9). Then, the search result window W including the explanatory information "Various, ..." of the dictionary searched word "various" is displayed (step T10).

[0080] This allows users to easily confirm, on the spot after searching the dictionary, that the word "various" that they are studying by searching the dictionary has been widely researched and studied, for example, by third-year high school students who are their rivals in the university entrance exams, and furthermore that it is a word that is difficult to remember, as it is ranked highly in the average number of searches by those same rivals.

[0081] FIG. 12 is a diagram showing screen transitions of the text display screen GD corresponding to the "search history compilation" in a state in which the dictionary application 23b of the communication terminal 20 is activated.

[0082] In the communication terminal 20, as shown in FIG. 12(A), when a text display screen GD showing expanded English text data is displayed on the touch panel display unit 21, the user U can touch (long press) to specify any range of the displayed English text as the study subject, and the control unit 22 will distinguishably display H the specified text range and display a [Show search history] button HK.

[0083] When the [Show search history] button HK is touched and a "search history compilation" is instructed with the specified text range as the study target (step T11 (Yes)), the control unit 22 obtains attribute data of the person to be compiled when "search history compilation" is performed (for example, "myself" and "Class 3A") from the compilation target person setting data memory area 23c (step T12).

[0084] Furthermore, the control unit 22 acquires the learning subject narrowing down conditions set by the user from the learning subject narrowing down condition data storage area 23d (step T13).

[0085] The control unit 22 transmits the user ID of the communication terminal 20, the text data of the specified range, the attribute data of the person being counted (including color data that can identify the attributes), and the data on the study subject narrowing down conditions to the learning support server 10 (step T14).

[0086] When the learning support server 10 receives the user ID sent from the communication terminal 20, the text data for the specified range, the attribute data of the person being counted, and the data on the learning target narrowing down conditions (step S1 → S9 (Yes)), the control unit 11 extracts words contained in the text and generates a word list (step S10).

[0087] If a learning subject narrowing condition ("top searched words", "forgetting characteristics", or "important words") is set (step S11 (Yes)), the control unit 11 narrows down the words in the word list generated in step S10 by eliminating words that do not match the narrowing condition in accordance with the set learning subject narrowing condition (step S12).

[0088] For example, when "top search count" is set as a condition for narrowing down the study subjects, the control unit 11 narrows down the words included in the word list to words that are difficult to remember and have a high search count (within the top 10), i.e., words that should be reviewed, based on the average search count ranking (see Figure 5(B)) stored in the search history compilation data storage area 12e.

[0089] Furthermore, for example, when "forgetting characteristics" is set as a condition for narrowing down the learning targets, the control unit 11 narrows down the words included in the word list to words effective for review based on the search history data (including search date and time: see FIG. 4(A)) of English words stored in the search history data storage area 12d in association with the received user ID (e.g., "123456787") and the optimal review timing from the previous learning timing set based on the human forgetting characteristics stored in the forgetting characteristics data storage area 12f.

[0090] Furthermore, for example, when "important words" is set as a condition for narrowing down the study subjects, the control unit 11 narrows down the words included in the word list to those words that appear frequently in tests such as university entrance exams and are stored in the important word data storage area 12g, that is, words that match the important words to be reviewed.

[0091] The control unit 11 sets the count value n, which counts the number of people (attribute data) set for the user, to “1” (step S13), and extracts words that have been previously searched for and are included in the search history data (see Figure 4(A)) of the person n=1 (here, “myself”) from among the words in the word list generated in step S10 or step S12 (step S14).

[0092] The control unit 11 sets an identification highlight color (red RE: see FIG. 7) set according to the counting target person n (here, "yourself") to the words in the extracted word list (step S15).

[0093] The control unit 11 determines whether the count value n of the person being counted (attribute data) is the last (here, "2") (step S16), and if it is not the last (n=2) (step S16 (No)), it increments the count value n (+1) to n=2 (step S17).

[0094] Then, from the words in the word list generated in step S10 or step S12, words that are included in the top (within the top 10) of the search rankings (see Figure 5(A)) of the person being counted n=2 (here, "Class 3A") are extracted (step S14), and a distinctive highlight color (blue BL: see Figure 7) that is set according to the person being counted n (here, "Class 3A") is set for the words in the extracted word list (step S15).

[0095] If the count value n of the person being counted (attribute data) is the last (n=2) (step S16 (Yes)), the control unit 11 updates the word list generated in step S10 or step S12 to a word list that retains the words that have been highlighted in steps S14 and S15 as words with search history for each person being counted (here, "myself" and "Class 3A") (step S18), and transmits the data of the updated word list (search history counting results) to the communication terminal 20 corresponding to the user ID received in step S1 (step S19).

[0096] When the communication terminal 20 receives the word list (search history tabulation result) data sent from the learning support server 10 (step T15 (Yes)), the control unit 22 highlights (HRE) in red RE the words that have search history for the tabulation target "yourself" in the text displayed on the text display screen GD within the range of text specified by the user, as shown in Fig. 12 (B), based on the words in the received word list that have search history for each tabulation target "yourself" and that have been highlighted in blue BL (step T16).

[0097] This allows the user to easily compare and confirm, on the spot, the English words that "the user" is studying by searching the dictionary among the English words contained in the range of text specified as the study target from a certain English text, with the English words that are ranked high in the search results and being studied by, for example, "Class 3-A," a rival for the university entrance exam set by the user, immediately after specifying the range of the English text to be studied.

[0098] If you set the target of the tally to only "yourself," the search history tally for "yourself" will be displayed; if you set it to only user attributes such as "Class 3A," the search history tally for the user corresponding to the set user attribute will be displayed.

[0099] In the operation of the embodiment, the case where the words that the user wants to learn are English words has been described, but it goes without saying that the same can be done for other languages, as well as for phrase (word) searches and search history compilation targeting technical terms, for example.

[0100] (Summary of the embodiment) According to the learning support system 1 of the embodiment, when the user attributes of the person to be tabulated (for example, a third-year high school student who is a rival in the entrance exam) are set (23c) on the communication terminal 20 and the user specifies a word (H) and commands "word search" (SK), the learning support server 10 performs a dictionary search for the specified word based on the dictionary database (12b) and determines whether the specified word is included in the top ranks of the search ranking (12e) based on the search history data (12d) accompanying the person to be tabulated's past dictionary searches, and also determines whether the specified word is included in the top ranks of the average search frequency ranking (12e).

[0101] If the specified word or phrase is included in the top search rankings, the learning support server 10 causes the communication terminal 20 to display, along with the search results (W) of a dictionary search for the specified word or phrase, a message "Other users are also looking for this word" M1 informing the user that the search ranking is high among the users being counted, and if the specified word or phrase is included in the top average search count rankings, the learning support server 10 causes the communication terminal 20 to display, along with the search results (W) of a dictionary search for the specified word or phrase, a message "This word is difficult for other users to remember" M2 informing the user that the search ranking is high among the users being counted.

[0102] This allows users to easily confirm, right after searching the dictionary, that the word they are studying has been widely researched and studied, as it has ranked highly in the search results for the people they have set as subjects of the survey, and furthermore that it is a word that is difficult to remember, as it has ranked highly in the average number of searches for the people they have set as subjects of the survey.

[0103] In addition, when a range of text containing multiple words is specified (H) on the communication terminal 20 and a command to "collect search history" is issued (HK), the learning support server 10 extracts, from the words contained in the specified range of text, words that are in the search history (12d) of the user who requested "collect search history" and words that are in the top search rankings (12e) of the person being collected.

[0104] Then, the learning support server 10 displays (HRE / HBL) the words in the user's search history and the words that are included in the top search rankings of the person being tabulated in the text range specified by the user that is being displayed on the communication terminal 20, distinguishing them, for example by color coding, so that they can be compared.

[0105] This allows the user to easily compare and confirm, on the spot, the words contained in the range of text specified as the study target, that "the user" has looked up in the dictionary and is studying, with the words that have been ranked high in search results and are being studied by the subjects of the survey.

[0106] Therefore, according to the learning support system 1 of the embodiment, it becomes possible to efficiently learn while easily checking on the spot to what extent the words and phrases to be learned have been looked up by other users.

[0107] In the above embodiment, a case has been described in which the user searches for words to be learned from various dictionary data such as an English-Japanese dictionary, a German-Japanese dictionary, a French-Japanese dictionary, and a Japanese dictionary stored in the dictionary database storage area 12b. However, it goes without saying that the type of database to be searched is not limited to dictionary data, and may also be encyclopedia data such as an encyclopedia or a picture book.

[0108] The encyclopedia data may contain images such as figures, pictures, and photographs, as well as audio, as explanatory information corresponding to words or phrases that are head words.

[0109] For example, if the dictionary data is an encyclopedia and the entry word is the name of a "bird," the image is a picture or photograph of the "bird" and the sound is the sound of the "bird." It goes without saying that even among the various types of dictionary data described above, there is dictionary data in which the explanatory information corresponding to the entry word includes, for example, an image representing the entry word (phrase) or a voice reading the entry word (phrase).

[0110] Hereinafter, as another embodiment, a case will be described in which a user searches for words to be studied from dictionary data in which explanatory information of entry words (words) includes images and sounds.

[0111] The encyclopedia data includes data on all types of books that compile explanatory information using words as headings, such as dictionaries, encyclopedias, picture books, etc.

[0112] (Other embodiments) FIG. 13 is a diagram showing a part of dictionary data in which a word or phrase that is an entry word of an encyclopedia stored in the dictionary database storage area 12b1 of another embodiment is associated with an explanatory text, an image, and a sound that are explanatory information of the same word or phrase.

[0113] In the dictionary data shown in Figure 13, the headword (word) "various" is stored in association with an explanatory sentence (translation) of the word "various," along with image data expressing the image of a wide variety (variety) and audio data of an example sentence.

[0114] When searching for headwords (phrases) in dictionary data (encyclopedia search), the search results include, along with an explanatory text, for example, an image display icon for displaying an image and an audio output icon for outputting audio; when the user selects the image display icon, the image data is opened and displayed, and when the user selects the audio output icon, the audio data is opened and output.

[0115] Figure 14 is a diagram showing examples of search history data for each user stored in the search history data memory area 12d of another embodiment, where (A) is a diagram showing an example of search history data for user A, and (B) is a diagram showing an example of search history data for user B.

[0116] The search history data memory area 12d stores, for each user ID stored and managed in the user management data memory area 12c, the entry word (phrase) that the user searched in the dictionary, the search date and time, whether or not an image was confirmed by specifying an image in the description information, and whether or not an audio confirmation was performed by specifying an audio.

[0117] Figure 15 shows an example of search history aggregated data stored in the search history aggregated data memory area 12e of another embodiment, where (A) shows a weekly search entry word ranking based on the search history of dictionary data corresponding to a range of users with a certain user attribute, and (B) shows an average search count ranking based on the same search history.

[0118] The search history summary data memory area 12e stores search history summary data including search rankings for words, the average number of searches for words, the ratio at which an image corresponding to the word was confirmed (image confirmation rate), the ratio at which an audio corresponding to the word was confirmed (audio confirmation rate), and the like, which are summarized for all users or by user attribute (by grade, class, etc.) for a period such as the entire period, a year, a month, or a week, based on the search history of words for each user stored in the search history data memory area 12d (including whether or not image confirmation and whether or not audio confirmation was performed).

[0119] FIG. 16 is a diagram showing screen transitions of the text display screen GD in response to a "phrase (word) search" in another embodiment of the present invention on the communication terminal 20. In FIG.

[0120] In another embodiment, when a user performs a dictionary search by specifying, for example, the word "various" using the learning support server 10 having the dictionary database (12b1), search history data (12d), and search history compilation data (12e), as in the above-described embodiment, a search result window W including explanatory information for the word "various" such as "various, ..." is displayed on the communication terminal 20 of the user, as shown in FIG. 16, when the word is ranked high in the search results for the person being compiled, a message "Other users are also looking for this" M1 is displayed, and when the word is ranked high in the average number of searches for the person being compiled, a message "This is a word that is difficult for other users to remember" M2 is displayed.

[0121] In addition, if the image confirmation rate of the person to be counted corresponding to the word "various" is high (for example, 50% or more), a thumbnail image GS of the image corresponding to the word "various" read from the dictionary database (12b1) and a message "It is highly likely that other users remember it by image" MG are displayed as information notifying the person to be counted that they are also checking the image. When the thumbnail image GS is specified by touch operation, the learning support server 10 opens and displays the image corresponding to the word "various".

[0122] Furthermore, if the voice confirmation rate of the person to be counted corresponding to the word "various" is high (for example, 50% or more), a voice icon IS including the message "Other users are also checking the voice data" is displayed as information notifying that the person to be counted is also checking the voice. When the voice icon IS is specified by a touch operation, the learning support server 10 opens and outputs the voice corresponding to the word "various".

[0123] This allows the user to easily confirm, on the spot where they have performed the encyclopedia search, that the word they are studying through a dictionary search has been widely researched and studied, ranking highly in the search results of the subjects set by the user, and further that it is a word that is difficult to remember, ranking highly in the average number of searches by the subjects, and that the subjects have also confirmed images and audio corresponding to the word.

[0124] FIG. 17 is a diagram showing screen transitions of the text display screen GD corresponding to the "search history compilation" of another embodiment on the communication terminal 20. In FIG.

[0125] Using the learning support server 10 having the encyclopedia database (12b1), search history data (12d), and search history compilation data (12e) of another embodiment, when a user specifies (H) a range of text including multiple words and phrases and commands (HK) a “search history compilation” as shown in FIG. 17(A), as in the above-described embodiment, the words (HRE) in the user’s search history and the words (HBL) included in the top search rankings of the person being compiled are displayed on the user’s communication terminal 20 in a manner that allows comparison, for example by distinguishing them by color, as shown in FIG. 17(B).

[0126] In addition, for a word included in the top of the search ranking of the person to be counted, if the image confirmation rate of the person to be counted is high (for example, 50% or more), a thumbnail image GS of an image corresponding to the word (here, "complex") read from the encyclopedia database (12b1) is displayed as information notifying that the person to be counted has confirmed the image as well, in association with the word "complex." When the thumbnail image GS is specified by a touch operation, the learning support server 10 opens and displays the image corresponding to the word "complex."

[0127] Furthermore, for a word included in the top of the search ranking of the person to be counted, if the voice confirmation rate of the person to be counted is high (for example, 50% or more), a voice icon IS is associated with the word (here, "approach") and displayed as information notifying that the person to be counted has confirmed the word as well. When the voice icon IS is specified by a touch operation, the learning assistance server 10 opens and outputs the voice corresponding to the word "approach."

[0128] This allows the user to easily compare and confirm, on the spot where they have specified the range of text, for example, the words contained in the text they have specified as the study target that they have searched in an encyclopedia and are studying, with the words that have appeared at the top of the search rankings and are being studied by the person being surveyed, including the fact that the person being surveyed has also checked the images and audio that correspond to the words.

[0129] In other embodiments described with reference to Figures 16 and 17, the display of the thumbnail image GS when the person being counted has a high image confirmation rate, and the display of the audio icon IS when the person being counted has a high audio confirmation rate, may be performed only when the user himself has not confirmed the image or audio corresponding to the relevant word (see Figure 14: "no image confirmation" / "no audio confirmation" in search history), thereby making the user aware that the person being counted is trying to memorize the word in question by relying on images and audio.

[0130] Therefore, according to another embodiment of the learning support system 1, it becomes possible to efficiently learn by simply checking on the spot to what extent the word or phrase you are trying to learn has been researched by other users, including whether other users are trying to memorize the word or phrase by relying on images or audio corresponding to the word or phrase.

[0131] The methods of each process by the learning support system 1 described in each of the above embodiments, i.e., the terminal process in the communication terminal 20 shown in the flowchart of Fig. 9 and the server process in the learning support server 10 shown in the flowchart of Fig. 10, can be stored in a medium of an external recording device such as a memory card (ROM card, RAM card, etc.), a magnetic disk (floppy (registered trademark) disk, hard disk, etc.), an optical disk (CD-ROM, DVD, etc.), or a semiconductor memory and distributed as a program that can be executed by a computer. Then, the control unit (CPU) of the electronic device reads the program recorded in the medium of the external recording device into the storage device, and the operation is controlled by the read program, thereby realizing the various functions described in each of the embodiments and executing similar processes by the above-mentioned methods.

[0132] In addition, the program data for realizing each technique can be transmitted over a communication network (N) in the form of program code, and the program data can be imported into an electronic device from a computer device (program server) connected to this communication network (N) and stored in a storage device to realize the various functions described above.

[0133] Furthermore, in each embodiment, the communication terminal 20 has a touch panel display unit 21, and the text display screen GD displayed on the touch panel display unit 21 is touched to specify the words to be searched for or the range of text to be studied. However, this is not limited to the above, and even if the communication terminal 20 has a display unit that is not a touch panel, such as a PDA (personal digital assistant), it is of course possible to realize a learning support system 1 similar to that described above by performing similar operations using keys or a pointing device.

[0134] The present invention is not limited to the embodiments, and can be modified in various ways without departing from the gist of the invention. The embodiments may be combined as appropriate, and in that case, the combined effects can be obtained. Furthermore, the embodiments include various inventions, and various inventions can be extracted by combinations selected from the multiple components disclosed. For example, if the problem can be solved and the effect can be obtained even if some components are deleted from all the components shown in the embodiments, the configuration from which the components are deleted can be extracted as an invention.
