The respondent terminal 30 is communicably connected to the learning support server 20 via the communication network NW2. There may be a wireless section between the learning support server 20 and the respondent terminal 30.

  An outline of the learning support system 100 of the present embodiment will be described. The learner terminal 10 is used by the learner L. If there is a problem that the learner L does not understand while learning, the learner L captures the problem with the learner terminal 10, generates a problem image, and transmits it to the learning support server 20. When the learning support server 20 receives the problem image from the learner terminal 10, the learning support server 20 acquires an answer corresponding to the problem indicated in the problem image.

  As will be described later, the learning support server 20 includes a database. The learning support server 20 acquires an answer corresponding to the problem of the problem image by searching the database. The learning support server 20 also presents the problem image to the respondent R. The respondent R uses the respondent terminal 30 to look at the problem image transmitted from the learner terminal 10 to the learning support server 20, and inputs a corresponding answer to the respondent terminal 30. 30 to the learning support server 20. That is, the learning support server 20 acquires the answer corresponding to the problem indicated by the problem image by searching the database and also from the respondent R. The learning support server 20 further acquires an answer corresponding to the problem indicated by the problem image by searching the website.

  When the learning support server 20 acquires the answer, the learning support server 20 returns the answer to the learner terminal 10 that has transmitted the problem image. The learner terminal 10 receives the answer from the learning support server 20 and displays it. In other words, if there is a problem that the learner L does not understand while learning, the learner L can answer the problem from the learning support server 20 with a simple operation of photographing and transmitting the problem image. Can be obtained. Therefore, the learner L does not take time for tasks other than learning, such as inputting a text of an unknown problem, and learning efficiency is improved. This will be specifically described below.

  The learner terminal 10 of the present embodiment is a mobile phone terminal, and more specifically a smartphone. Note that the learner terminal 10 may be a personal computer, and may be connected to the learning support server 20 via a cable so as to be communicable. FIG. 2 is a block diagram illustrating a configuration of the learner terminal 10. The learner terminal 10 includes a photographing unit 11, a display unit 12, a calculation processing unit 13, a transmission / reception unit 14, an input unit 15, and a storage unit 16.

  The photographing unit 11 is a camera including an optical system, an image sensor, and an image processing circuit. In the learning support system 100, the learner L particularly uses the photographing unit 11 to photograph a problem collection or a problem printed on a print and generate a problem image. When learning is performed using a collection of questions and prints, the learner L can capture a problem and generate a problem image if there is a problem that is not known. The imaging unit 11 corresponds to a “problem image generation unit”. The photographing unit 11 as a problem image generation unit may be a scanner for reading a problem book or a problem printed on a print. When the learner L is learning by displaying a problem on the display unit 12, the photographing unit 11 as the problem image generation unit captures the image displayed on the display unit 12 and displays the problem image. It may be generated.

  The display unit 12 displays display content. Specifically, an operation screen for photographing a problem to generate a problem image and transmitting it to the learning support server 20, a problem image generated by the photographing unit 11, and transmission from the learning support server 20 Used to display the answers that have been made. The display unit 12 of the present embodiment is composed of a liquid crystal panel.

  The arithmetic processing unit 13 performs various arithmetic processes. The arithmetic processing unit 13 executes various types of processing described below according to the input from the input unit 15 and the data transmitted from the learning support server 20 by executing the learning terminal program using an arithmetic processing unit and a memory. Do. The learning terminal program may be downloaded through the communication network NW1, stored in the storage unit 16, and read out from the storage unit 16, or may be executed by being stored in a portable storage medium (not shown). May be read and executed. The processing of the arithmetic processing unit 13 will be described later.

  The transmission / reception unit 14 transmits / receives data by wireless communication. In the present embodiment, in particular, a user name (learner ID) and a password, which will be described later, and a problem are transmitted to the learning support server 20 and an answer is received from the learning support server 20. The problem is sent in the form of an image. The transmission / reception unit 14 that transmits the problem image corresponds to a “problem transmission unit”. The answer from the learning support server 20 may be received by the push transmission by the learning support server 20 or may be downloaded from the learning support server 20 when the learner terminal 10 accesses the learning support server 20. Good. The transmission / reception unit 14 that receives an answer corresponds to an “answer receiving unit”.

  The input unit 15 receives various inputs of the learner L who is the user of the learner terminal 10. The input unit 15 of the present embodiment includes a touch sensor and buttons. The touch sensor is provided so as to overlap the display unit 12 configured with a liquid crystal panel, and a touch panel is configured with the liquid crystal panel.

  Various types of information are stored in the storage unit 16. In the present embodiment, in particular, the storage unit 16 stores the problem image generated by the photographing unit 11. Further, as described above, the storage unit 16 also stores a learner terminal program executed by the arithmetic processing unit 13.

  Hereinafter, the process of the arithmetic processing unit 13 in the learner terminal 10 will be described in detail. The arithmetic processing unit 13 displays a login screen on the display unit 12 in accordance with the input of the learner L to the input unit 15. When the learner L inputs the user name and password using the input unit 15 on the login screen, the arithmetic processing unit 13 transmits the user name and password from the transmission / reception unit 14 to the learning support server 20. When the transmission / reception unit 14 acquires authentication information from the learning support server 20, the arithmetic processing unit 13 starts processing for problem image transmission described below. This user name corresponds to a learner ID described later.

  If there is a problem that is not known during learning, the learner L uses the photographing unit 11 to photograph the problem. As a result, the photographing unit 11 generates a problem image. The arithmetic processing unit 13 displays the generated problem image on the display unit 12. The problem image to be transmitted may be selected from images captured in the past and stored in the storage unit 16.

  The arithmetic processing unit 13 superimposes a mark for identifying the problem part on the problem image displayed on the display unit 12 according to the input from the learner to the input unit 15. As described above, the arithmetic processing unit 13 that processes the problem image by superimposing the mark for identifying the problem part on the problem image generated by the photographing unit 11 corresponds to a “problem image processing unit”.

  In this embodiment, the mark superimposed on the problem image is a frame surrounding the problem part in the problem image. The mark superimposed on the problem image may be a mark indicating the start position of the problem part, or may be a color superimposed on the problem part. By attaching such a mark, the learning support server 20 side can easily determine which part in the problem image is the problem part.

  The arithmetic processing unit 13 transmits the processed problem image from the transmission / reception unit 14 to the learning support server 20, and at this time, appends additional information to the problem image. A problem image to which attached information is added is transmitted from the transmission / reception unit 14. Note that the transmission of a problem from the learner terminal 10 to the learning support server by the learner L is also referred to as “posting” in this specification. In this embodiment, posting is performed by transmitting a problem image.

  In the present embodiment, the attached information transmitted in addition to the problem image includes the user name (learner ID), the transmission date and time, and information on the subject of the problem. The subject information is information indicating whether the problem is a national language, mathematics, science, society, or English, and is selected by the learner L. By adding subject information, the learning support server 20 can efficiently obtain answers using subject information. For example, when the learning support server 20 acquires an answer by searching, the search range can be narrowed down according to the designated subject. Further, when the respondent R answers the problem, the problem can be presented to the respondent R in charge of the designated subject.

FIG. 3 is a diagram illustrating an example of a display screen of the display unit 12 of the learner terminal 10 when a question image is transmitted. This display screen includes the generated problem image 31. A mark 311 attached by the user is superimposed on the problem image. The display screen is provided with a subject selection icon 32 for selecting a subject from Japanese, mathematics, science, society, and English. The learner L selects a subject by tapping any icon. When the user taps the transmission button 33, a problem image including information on the subject selected as the attached information is transmitted to the learning support server 20. When the learner L taps the cancel button 34, the problem image is canceled and the process returns to the step of generating the problem image.

  The arithmetic processing unit 13 does not add a user name as attached information for each transmission (post) of a problem and transmits it, so that the learner L logs in using a user name and a password, so that the learner terminal 10 and the learning support server 20 may establish a session, and thereafter, the learning support server 20 may identify the learner L using a cookie. In addition, the arithmetic processing unit 13 may not add the transmission date and time as the attached information, but transmit the information on the reception date and time to each post in the learning support server 20 on the receiving side. Further, the arithmetic processing unit 13 may add one or more pieces of information below as attached information to the problem image instead of or in addition to the subject information.

  As ancillary information, information indicating whether the learner L desires to answer and explain a problem posted as an answer or whether to expect an answer and explanation of a posted problem topic may be added. That is, the problem transmitted by the learner L is not limited to the problem that the learner L does not understand. Even if a learner L solves a problem, if he / she wants to establish learning by solving the problem's category, the problem L's problem, its answer and explanation are posted by posting the solved problem. Can be obtained as an answer. By adding this auxiliary information, the learning support server 20 can determine whether the learner L cannot solve the posted problem itself or whether to solve the problem category. Even when the learning support server 20 is requested to answer or explain the posted problem, the learning support server 20 obtains the answer and explanation of the problem along with the answer and explanation of the problem, and transmits it to the learner terminal 10. If the answer and explanation of the problem cannot be obtained by the search, the answer and explanation of the topic are transmitted to the learner terminal 10.

  Further, information designating the respondent R may be added as attached information. When the learning support server 20 receives the question image, the learning support server 20 obtains an answer corresponding to the question posted by searching the database, and also obtains an answer from the respondent R. If the information designating the respondent R is added, the transmitted problem can be presented only to the designated respondent R so as to obtain an answer from the designated respondent R. . Alternatively, when a question is presented to a plurality of respondents R, the respondent R designated for the presented question may be specified.

  In addition, a learner's question comment may be added as attached information. When the attached information is added, the learning support server 20 can make an answer in accordance with the intention of the learner L's question using the learner's question comment when the answerer R makes an answer.

  As described above, the arithmetic processing unit 13 performs processing for superimposing the mark indicating the problem part on the problem image generated by the photographing unit 11, and further adds the attached information to the transmission / reception unit. However, such a problem image may be stored once in the storage unit 16, and after a plurality of problem images are stored in the storage unit 16, they may be transmitted together. That is, the transmission / reception unit 14 may collectively transmit a plurality of problem images to the learning support server 20. As a result, each time there is a problem that the learner L does not understand during the learning, the learner L takes a picture of the problem, prepares a problem image, and collects them together at any timing such as when the learning is completed. 20 can be transmitted.

  Next, the configuration of the learning support server 20 will be described. The learning support server 20 is a server on the Internet.

In particular, the transmission / reception unit 21 receives a question image to which a user name (learner ID), a password, and attached information are added from the learner terminal 10, and transmits an answer to the learner terminal 10. The transmission / reception unit 21 that receives the problem image corresponds to a “problem reception unit”. In addition, the transmission / reception unit 21 transmits a question presentation screen indicating the posted problem to the respondent terminal 30 and receives the answer input by the respondent R from the respondent terminal 30.

  The calculation processing unit 22 includes a character recognition unit 221, an automatic calculation unit 222, a search unit 223, a problem presentation screen generation unit 224, and a DB update unit 225. The arithmetic processing unit 22 corresponds to an “answer acquisition unit”. These configurations are realized by the arithmetic processing unit 22 executing the learning support program. The learning support program may be downloaded via the Internet, stored in a storage unit (not shown), read out from the storage unit by the arithmetic processing unit 22, or stored in a storage medium (not shown). It may be executed by reading from.

  The character recognition unit 221 performs character recognition processing on the problem image received from the learner terminal 10 by the transmission / reception unit 21. First, the character recognition unit 221 recognizes a mark superimposed on the problem image, and performs character recognition on the problem portion indicated by the mark. Specifically, the character recognition unit 221 performs character recognition on a portion surrounded by a frame that is a mark. In addition, the existing OCR (Optical Character Reader) technology can be adopted for character recognition.

  The automatic calculation unit 222 performs calculations included in the answers and explanations, and completes an answer to be transmitted to the learner terminal 10. For example, the automatic calculation unit 222 performs calculation of an automatic calculation algorithm included in an answer or a comment for a mathematical problem, and translates English included in the answer or a comment for an English problem.

  The search unit 223 performs various processes. First, the learner matching process will be described. Prior to the description of the learner matching process of the search unit 223, the learner matching storage unit 24 will be described. FIG. 5 is a diagram illustrating a data structure of the learner matching storage unit 24. The learner matching storage unit 24 stores a learner ID and a password for each learner. The learner ID is identification information unique to each learner L, and is composed of a combination of a plurality of alphanumeric characters. The learner ID is recognized as a “user name” by the learner L. This learner ID corresponds to “learner information”. The password is a combination of a plurality of alphanumeric characters designated by the learner L.

  The learner matching storage unit 24 stores the member name, district, school name, grade, grade, and desired school as attributes of the learner L. The member name is the real name of the learner L. The district is the residential district of the learner L. The school name is the name of the school to which the learner L belongs. The grade is the grade of the learner L and is one of elementary school 1-6, middle school 1-3, or high school 1-3. The desired school is the name of the school where the learner L wants to go on. Further, the learner matching storage unit 24 stores a history of posts and answers of the learner L. The learner L can browse his / her history from the learner terminal 10 as appropriate.

As described above, since the learner ID (user name) and password are transmitted from the learner terminal 10, the search unit 223 uses them to refer to the learner matching storage unit 24 and learners. L is collated. When the combination of the learner ID and the password transmitted from the learner terminal 10 matches the data stored in the learner matching storage unit 24, the learning support server 20 sends the learner ID to the learner terminal 10. By replying, the learner L is authenticated. The learner terminal 10 adds this learner ID as attached information when transmitting the problem image. The search unit 223 of the learning support server 20 searches the learner matching storage unit 24 using the learner ID transmitted from the learner terminal 10 together with the problem image, and acquires the learner's grade information. To do.

  Next, problem matching processing by the search unit 223 will be described. First, the terms “answer”, “answer”, and “commentary” used in this specification will be described. In this specification, the “answer” refers to some reply to the learning support server 20 receiving a problem from the learner terminal 10, the answer and explanation of the problem, the problem class and the answer and explanation, A notification such as waiting for an answer by the respondent R, which includes information related to the problem (for example, a general explanation of the unit) and cannot obtain a valid answer and explanation, also corresponds to “answer”. Therefore, “answer” is a broad concept including “answer” and “commentary”. On the other hand, “answer” is an answer to a problem, and “explanation” is an explanation for obtaining the answer.

  The search unit 223 searches for the problem matching storage unit 23 to perform problem matching. Prior to the description of the problem matching process, the structure of the data stored in the problem matching storage unit 23 will be described. . FIG. 6 is a diagram illustrating a data structure of the problem matching storage unit 23. In the problem matching storage unit 23, for each answer, the answer No. , Problem content, answer content, answer type, subject, unit, subject grade, and subject time are stored in association with each other.

  Answer No. Is a number unique to each answer. The question content is content of the question corresponding to the answer. The problem content stores a set of parts (problem parts) in one or a plurality of sentences. Among these problem parts, in addition to the problem parts of the words that make up the problem sentence, for example, for mathematical problems, a solution of a specific linear equation such as “solution of linear equation” (for example, y = 3) may be included instead of universal parts (general problem parts).

  The answer contents are answer contents corresponding to the question contents, specifically, answer contents and explanation contents of the question contents. The answer content is one or more sentences. In these sentences, for example, for mathematics problems, it is not a specific linear equation solution (for example, y = 3), such as “solution of linear equation”, but a universal part (general answer part) May be included. In addition, the sentence of the answer content may include an algorithm for calculation that should be performed by the automatic calculation unit 222. As described above, the problem matching storage unit 23 stores a general explanation of a unit as an answer content. However, an answer whose answer content is a general explanation of a unit is stored in the question content. I don't have any data.

  The subject and unit are the subject and unit of the problem content. The target school year is a school year for learning a problem content problem in a typical curriculum of a school, and the target time is a time for learning the problem content (for example, “1 semester”). By combining the target school year and the target time, the school year and semester (for example, “second year of junior high school 2 semester”, etc.) in which the problem content is learned is specified.

The search unit 223 performs morpheme analysis on the characters recognized by the character recognition unit 221, and uses morphemes obtained by removing particles, auxiliary verbs, and the like as keyword sets. Further, the search unit 223 recognizes that a mathematical expression such as “x ² + ax + b = 0” is a “quadratic equation” by analyzing the mathematical expression using a predetermined algorithm. The search unit 223 includes a set of keywords extracted from the problem image, subject information transmitted as ancillary information along with the problem image, the transmission date and time of the problem, and the learner L acquired by searching the learner matching storage unit 24. The problem matching is performed by searching the problem matching storage unit 23 based on the information of the grade.

  The search unit 223 compares the subject information transmitted as the attached information with the subject stored in the problem matching storage unit 23, and obtains the grade of the learner L acquired by the search in the learner matching storage unit 24. Is compared with the subject grade stored in the problem matching storage unit 23, and the transmission date and time transmitted as the attached information is compared with the target time stored in the problem matching storage unit 23. The search unit 223 further extracts a set of extracted keywords and a set of problem parts of the problem content for answers whose subjects are completely matched, whose grades are completely matched, and whose times are within a predetermined error range. And a matching score indicating the degree of coincidence between them is calculated.

  Here, the reason that only subjects whose subjects match completely is the target because it is considered that there is no response corresponding to the transmitted problem among responses whose subjects are different. Also, in this embodiment, assuming daily preparation and review as the purpose of learning, only the answers whose school years are completely the same and the time is within a predetermined error range are targeted. Different designs are possible. For example, when an examination study is assumed as the purpose of learning, all answers having a target period of the learner's academic year and semester (period) may be targeted.

  Furthermore, the purpose of learning may be specified by the learner at the learner terminal 10 and the specified information may be transmitted to the learning support server 20 along with the problem image as attached information. An icon for designating the purpose of learning may be provided on the display screen shown in FIG. The information specifying the learning purpose corresponds to “learning purpose information”. In this case, the transmission / reception unit 21 of the learning support server 20 receives the learning purpose information, and the search unit 223 has an appropriate range according to the learning purpose information, the learner's grade information, and the transmission date and time of the problem image. , And subject matching can be performed for answers whose target grade and target time match (or are included) within the set range.

  The search unit 223 searches the problem matching storage unit 23 for the problem content for the posted problem, and acquires the answer content associated with the searched problem content as an answer. 7 to 9 are diagrams illustrating an example of matching between a set of keywords extracted from a problem image and a set of problem parts of problem content. In this example, a mathematical problem image has been transmitted as the problem image.

As shown in FIG. 7, the character recognizing unit 221 reads “secondary equation x ² + ax + b = 0” from the problem image.
The solution was x = 2 and x = 3. Find the values of a and b. "Is recognized. That is, the posted problem is a problem of obtaining the coefficient when the solution of the quadratic equation is obtained. The search unit 223 performs a morphological analysis on this sentence, and removes unnecessary words to obtain “secondary equation”, “x ² + ax + b = 0” (secondary equation), “solution”, “x = 2”. (Secondary equation solution 1), “x = 3” (Secondary equation solution 2), “a” (Secondary equation coefficient 1), “b” (Secondary equation coefficient 2), “Value” , And extract the keyword “sought”.

In the problem matching storage unit 23, [quadratic equation] “solution” [quadratic equation solution 1] [quadratic equation solution 2] [quadratic equation coefficient 1] [quadratic equations] Coefficient 2] A set of problem parts “determining” is stored. Here, “” is a problem part of a word, and [] is a general problem part. In addition, this problem content includes the following answer content: “This is a problem of finding the coefficient of the quadratic equation. 2] are assigned to the quadratic equations, respectively, and {Automatic calculation 1} (Formula 1) is obtained by substituting [Solution 1 of the quadratic equation]. Substituting [Secondary equation solution 2] gives {Automatic calculation 2} (Equation 2), and solving Equation 1 for [Secondary equation coefficient 1] gives {Automatic calculation 3} (Equation 3). Substituting Equation 3 into Equation 2 yields {Automatic Calculation 4} (Equation 4). Substituting Equation 4 into Equation 3 yields {Automatic Calculation 5} (Equation 5). " Is associated. Here, [] is a general-purpose answer part, and {} is an automatic calculation algorithm (calculation formula).

  FIG. 8 is a diagram illustrating a matching result between the extracted keyword and the problem part. In this example, matching is performed as illustrated, and the matching score is, for example, “80”. The matching score may be calculated by a matching ratio in the set of extracted keywords, a matching ratio in the set of problem parts, or other methods. Alternatively, each keyword or problem part may be weighted and the matching ratio may be calculated to obtain a matching score. This matching score indicates the accuracy of the search result.

  The search unit 223 performs matching between the problem of the problem image and the problem content. If the matching score is equal to or higher than a first threshold (for example, 80), the problem content is a problem content that matches the problem of the problem image. If it is determined that the matching score is greater than or equal to a second threshold (for example, 50) and less than the first threshold, it is determined that the content is a problem content (classification) similar to the problem of the problem image, and the matching score is If it is less than the threshold value of 2, it is determined that the problem content is not related to the transmitted problem.

  When the matching score is greater than or equal to the second threshold, the search unit 223 extracts the answer content from the problem matching storage unit 23. When the search unit 223 extracts the answer content (see the bottom row in FIG. 7), the search unit 223 applies the extracted keyword to the general-purpose answer part, and the automatic calculation unit 222 assigns the extracted keyword to the automatic calculation algorithm. By acquiring the results, the answers (answers and explanations) shown in FIG. 9 are acquired. The transmission / reception unit 21 transmits the answer acquired by the search unit 223 to the learner terminal 10.

  The learner terminal 10 receives the answer and displays it on the display unit 12. FIG. 10 is a diagram illustrating a display screen example of the display unit 12 of the learner terminal 10. This display screen is a screen showing a list of received answers. This display screen includes information on a list of posted problems and their answers. The posted problem information includes the problem image, transmission date and time information, and selected subject information. For each answer in the answer list, the answer type (answer and explanation of the submitted question, answer and explanation of the posted question topic, answer from respondent R, web search results, etc.), subject, unit, and the answer Includes buttons for viewing specific content.

  When the learner L designates a button for viewing the specific content of the answer, the arithmetic control unit 13 downloads the content of the corresponding answer from the learning support server 20 and displays it on the display unit 12. At this time, the learning support server 20 transmits a notification to that effect to a predetermined destination, assuming that the content of the answer is received by the learner terminal 10. Here, the predetermined destination is, for example, the address of the operator of the learning support system 100 or the address of the respondent R who made the answer. As a result, the operator can know that the answerer R has made an answer and that the learner L has seen it, and the answerer R knows that the learner L has seen the answer he has made. it can.

  Since the learner L can make an additional question based on the answer after obtaining the answer, the display screen is also provided with a button for that purpose. The display screen also includes a button for returning to the previous screen. The arithmetic processing unit 13 of the learner terminal 10 accepts the learner's L question with respect to the received answer together with information for identifying the received answer by the text input of the learner L. This question is transmitted from the transmission / reception unit 14 to the learning support server 20. Note that information specifying a posted problem may be added to the question instead of the information specifying the received answer or in addition to the information specifying the received answer.

Further, the additional question for the received answer is not limited to the text input by the learner L. For example, a button such as “I don't know” is provided on the display screen on which the answer is displayed. Information indicating that the learner L has indicated the button may be transmitted to the learning support server 20. The learning support server 20 can determine that the learner L has not yet understood the answer that has already been transmitted by transmitting a textual question or instruction information of an evaluation button indicating “I don't know”. In this case, the learning support server 20 can search the learning matching storage unit 23 again or present the question to the respondent R. When the question is presented again to the respondent R, the question entered by the learner L is also presented.

  Moreover, when the answer used as the object of the question is an answer by the respondent R, the learning support server 20 may present the question presentation again to the respondent R who made the answer. Specifically, the learning support server 20 transmits the question to the address (destination) of the respondent who made the answer together with the text question and the instruction information of the evaluation button “I don't know”. The respondent R can make a reply including a more detailed explanation and a more basic explanation. Further, the frequency and tendency of such questions may be stored as the requested answer depth as data of the learner in the learning storage unit 24 for learners. By doing so, when making the first answer, it is possible to determine how much detailed or basic answer should be given by referring to the requested answer depth of the learner L.

  FIG. 11 is a display screen showing only a result of web search when an answer having a matching score equal to or higher than the second threshold is not found by searching the problem matching storage unit 23 by the search unit 223. In this display screen, a problem is presented in the same manner as described above, and a message indicating that an answer from the respondent R is awaited and information on valid websites obtained as a result of web search are shown.

  Returning to FIG. 4, the problem presentation screen generation unit 224 generates a problem presentation screen for presenting the posted problem to the respondent R. Before describing the problem presentation screen generation process, first, the posting storage unit 25 and the DB update unit 225 will be described. FIG. 12 is a diagram illustrating a data structure of the posting storage unit 25. The posting storage unit 25 sets a posting number for each posting. , Problem image, subject, grade, transmission time, status, answered answer, priority.

  Post No. Is a number unique to each post. The problem image has been transmitted from the learner terminal 10. Instead of the problem image or in addition to the problem image, the text recognized by the character recognition unit 211 may be stored. The subject and the transmission time are the subject and the transmission time in the attached information of the problem image. The school year is retrieved from the learner matching storage unit 24 by the retrieval unit 223.

  Whether the status is a DB search answer for the post (replies acquired by database search have been replied), respondent answers have been completed (answers acquired from respondent R have been replied), search answers The response status of the posting, such as whether the answer has been answered and the answerer has been answered, the answer to the web search has been completed (the answer acquired by the web search has been returned), or the answer has not been answered. Reply completed answers are answers that have already been replied to the post. This reply-completed answer may have been obtained by searching the search unit 223, may have been obtained from the respondent R, or may have been obtained by web search. Or any combination thereof.

The priority is information indicating which post reply is desired early (urgent level), and the higher the value, the higher the urgency level. The respondent R can recognize which post is more urgent by referring to this priority. The priority increases as the matching score in the search unit 223 for the posting decreases. Further, the priority is higher when the answer by the respondent R has not been made than when the answer by the respondent R has already been made. In the case where the answer and explanation of the posted problem itself are obtained by the automatic calculation section 222, the problem matching storage section 23 is searched, and the answer and explanation of the posted problem itself is searched. Is given the same priority.

  Further, the priority becomes higher as the elapsed time from the transmission date and time to the current time is longer. Note that the reference time for measuring the elapsed time is not limited to the transmission date / time of the problem image, but the date / time when the learning support server 20 received the problem image, and the search unit 223 searches the problem matching storage unit 23 to obtain the answer. The date and time may be the date and time when the search unit 223 searches the problem matching storage unit 23 for the acquired answer to the learner terminal 10.

  The DB update unit 225 updates the status of each post, the reply completed reply, and the priority in the post storage unit 25. That is, when a certain reply is transmitted to the learner terminal 10 for a certain post, the reply is updated as a reply completed reply. When the matching score is calculated by the search unit 223, the priority is calculated and updated, and the priority is also updated when an answer is obtained from the respondent.

  When presenting a problem to the respondent terminal 30, the problem presentation screen generation unit 224 generates a problem presentation screen using the data stored in the posting storage unit 25. On the problem presentation screen, for each post, a post No. , Problem image, subject, school year, transmission time, status, answered reply, and priority information.

  FIG. 13 is a diagram illustrating an example of a problem presentation screen generated by the problem presentation screen generation unit 224. Each question includes urgency (priority), question image thumbnail, transmission date / time, subject, school year, unit information, and a button for respondent R to answer each question. . This question presentation screen is transmitted from the transmission / reception unit 21 of the learner support server 20 to each respondent terminal 30.

  When the DB update unit 225 receives an answer from the respondent terminal 30, the DB update unit 225 adds the answer to the problem matching storage unit 23. Thus, each time an answer is acquired from the respondent R, the problem matching storage unit 23 is enriched, and thus the matching score of the problem matching process by the search unit 223 is improved.

  Next, the respondent terminal 30 will be described. The respondent terminal 30 is a normal personal computer. The respondent terminal 30 may be a mobile terminal (for example, a smartphone). The respondent terminal 30 is used by the respondent R. The respondent R includes an exclusive respondent and a general respondent. Exclusive respondents are registered as lecturer staff in the learning support system 100, and general respondents are an unspecified number of persons.

  In the answer received by the learner L, whether it is an answer from a dedicated answerer or an answer from a general answerer may be clearly indicated. Different question presentation screens may be generated for exclusive respondents and general respondents. For example, the detailed attributes (school name, grade, etc.) of the learner L may be displayed on the question presentation screen for exclusive respondents.

  The respondent R can display the problem presentation screen on the respondent terminal 30 and input an answer to the presented problem. At this time, the respondent R determines which question is to be answered by referring to the value of urgency. In addition, in the case where an incentive for answering is given to the respondent R, a higher incentive may be given as an answer is given to a problem with a high degree of urgency.

The answer by the respondent R can be input using a normal input device such as a mouse, a keyboard, or a touch panel. When the answerer R inputs the answer text to the answerer terminal 30, the answerer R transmits the answer to the learning support server 20. The respondent R can also answer by taking a handwritten answer, generating a reply image, taking the reply image into the respondent terminal 30 and sending it to the learning support server 20. Further, the respondent R can input the answer by handwriting. In this case, an image generated by the handwriting input is transmitted to the learning support server 20.

  When the learning support server 20 acquires an answer from the respondent terminal 30, the DB update unit 225 updates the data of the corresponding post in the post storage unit 25, and the transmission / reception unit 21 transmits this answer to the learner terminal 10. . FIG. 14 is a diagram illustrating an example of a display screen of the display unit 12 of the learner terminal 10. This display screen is a screen showing a list of received answers. The answer list includes answers that have already been obtained by the search by the search unit 223 in addition to the answers newly acquired from the respondent R. The answer newly acquired from the respondent R is marked with “NEW” indicating that it is a new arrival answer.

  In addition, as described above, the DB update unit 25 updates the problem matching storage unit 23 by adding the answer acquired from the respondent terminal 30 to the problem matching storage unit 23. When answering, input information necessary for the update. When the respondent terminal 30 is instructed to give a “answer” button on the question presentation screen shown in FIG. 13, a screen for inputting a response is displayed. Corresponding to the data structure of the unit 23 (see FIG. 6), a unit for inputting a unit, a target grade, and a target time is included.

  When the DB update unit 25 obtains an answer from the respondent R, the problem image and / or sentence content obtained by performing character recognition on the problem image and / or the problem image that is the subject of the answer The answer obtained from the respondent R is the answer content, the answer type is the answer by the respondent, the subject is the subject specified in the post that was the subject of the answer, the unit, the target grade, As the answerer R specifies, the answer No. And a new answer is stored in the problem matching storage unit 23. The DB update unit 25 adds only answers from dedicated respondents to the problem matching storage unit 23 and does not add answers from general respondents to the problem matching storage unit 23. The quality of answers stored in the storage unit 23 may be secured.

  Next, processing up to replying in the learning support system 100 will be described. FIG. 15 is an operation flowchart of the learning support system 100. First, the learner terminal 10 captures a problem (step S11) and generates a problem image. Then, the problem image is processed and attached with attached information, and then transmitted to the learning support server 20 (step S12).

  When the transmission / reception unit 21 of the learning support server 20 receives the problem image from the learner terminal 10 (step S21), the search unit 223 searches for the learner L using the learner ID in the attached auxiliary information ( Step S22). In addition, the character recognition unit 221 of the learning support server 20 recognizes characters from the problem image, the search unit 223 extracts a set of keywords from the recognized character string, and the problem matching storage unit 24 extracts the keyword as problem content. An answer having a set of problem parts corresponding to the set of keywords is searched (step S23). When an answer is obtained by the search of the search unit 223, the transmission / reception unit 21 transmits the search result to the learner terminal 10 (step S24). The learner terminal 10 receives this search result (step S13).

When the search result is obtained by the search unit 223, the DB update unit 225 updates the posting storage unit 25 in accordance with the matching score of the search (step S25). When the posting storage unit 25 is updated, the problem presentation screen generation unit 26 generates a problem presentation screen (step S36) and transmits it to the respondent terminal 30 (step S27). The problem presentation screen generator 2
6 may generate a problem presentation screen when there is a request for a problem presentation screen from the respondent terminal 30. The respondent terminal 30 receives this question presentation screen (step S31), and presents the question presentation screen to the respondent R by displaying the question presentation screen. On the other hand, when the answerer R inputs an answer, the answerer terminal 30 acquires the answer (step S32) and transmits the acquired answer to the learning support server 20 (step S33).

  The transmission / reception unit 21 of the learning support server 20 receives the reply transmitted from the respondent terminal 30 (step S28) and transmits it to the learner terminal 10 (step S29). The learner support server 20 may transmit the answer to the learner terminal 10 by push transmission, or may transmit the answer to the learner terminal 10 in response to a request from the learner terminal 10. The learner terminal 10 receives the answer (step S14) and displays it on the display unit 12. Thereby, the learner L can confirm the answer. In the above description with reference to FIG. 15, description of the update processing of the problem matching storage unit 23 by the DB update unit 23 is omitted.

(Modification)
In the above embodiment, the problem is transmitted as a problem image from the learner terminal 10 to the learning support server 20, and the learner support server 20 performs character recognition on the problem image. However, the problem may be transmitted from the learner terminal 10 to the learning support server 20 as text data. This text data may be obtained by input by the learner L or may be obtained by performing character recognition on the problem image at the learner terminal 10. In addition, a problem image is transmitted from the learner terminal 10 to the learning support server 20, character recognition is performed by the learning support server 20, text data is acquired, and the text data is once returned to the learner terminal 10, After the learner L confirms and corrects, the learner terminal 10 may reply to the learning support server 20. Furthermore, the problem transmitted from the learner terminal 10 to the learning support server 20 may be transmitted in the form of moving image data or audio data instead of the problem image or in addition to the problem image. The answer content stored in the problem matching storage unit 23 may also be content such as an image, a moving image, and sound.

  In the above embodiment, when the learning support server 20 receives the problem image, the character recognition unit 221 performs character recognition on the problem image, and performs problem matching using the result of character recognition. The part 221 may be omitted. In this case, the question matching storage unit 23 stores a question image as the question content for each answer, and the search unit 223 stores the received question image and the question matching storage unit 23. Pattern matching with the question image as the question content is performed, and an answer corresponding to the received question image is searched. In addition, when a problem posting is made with voice data, a voice recognition unit that performs voice recognition on the voice data may be provided instead of the character recognition unit 21.

  Further, in the above embodiment, the problem matching storage unit 23 stores the content of the complete answer that is the answer to the learner L alone as the answer content. The question matching storage unit 23 may store answer parts that form a complete answer by being combined with each other. In this case, the search unit 223 searches for a combination of a plurality of problem parts that partially match a plurality of keywords included in the received problem image, and answer contents (answer parts) associated with these problem parts. To complete a complete answer.

  Further, a part of the configuration of the learning support server 20 may be provided in one or a plurality of other devices that are communicably connected to the learning support server 20. For example, the storage units 23 to 25 may be provided in a database server different from the learning support server 20.

  In the above embodiment, the configuration and processing in which the learner L obtains an answer and browses the answer have been described. However, the learning support system 100 allows the learner L to evaluate the answer. A configuration may be provided. Specifically, a screen for displaying an answer is provided with a button for evaluating the answer, and when the button is designated, a screen for evaluating is displayed. On the screen for making an evaluation, the learner L can select an evaluation option such as “Very useful”, “Okay”, and can input text for evaluation. The learner L selects an evaluation and inputs a text, and then instructs transmission of the evaluation.

  The arithmetic processing unit 13 transmits the evaluation selected from the transmission / reception unit 14 and the input text to the learning support server 20 in accordance with the transmission instruction of the learner L. The function of the arithmetic processing unit 13 corresponds to an “evaluation unit”, and the transmission / reception unit 14 that transmits the selected evaluation and the input text corresponds to an “evaluation transmission unit”. Such an evaluation on the answer of the respondent R may be counted as an incentive to the respondent R in the learning support server 20. The transmission / reception unit 14 transmits the evaluated and input text to another predetermined destination, for example, the destination of the respondent R who made the answer, instead of or in addition to the learning support server 20. May be.

  In the above embodiment, the answer and explanation of the question content are stored as the answer content in the question matching storage unit 23. However, depending on the answer, only the answer or only the explanation may be stored.

  Further, the search unit 223 may use the learner L's post history stored in the learner matching storage unit 24 as a search refinement condition in the problem matching process for posts from the learner L. Good.

  Furthermore, in the above embodiment, when the problem posted to the respondent R is presented, information on the degree of urgency (priority) is presented. However, the present invention is not limited to this. For example, the priority is a predetermined threshold value. Only the above problems may be presented to the respondent R, and the problems whose priority is lower than the predetermined threshold may not be presented to the respondent R, or only the problems whose priority is the predetermined threshold, or Marks such as “very urgent” and “hurry” may be attached according to the priority. Furthermore, on the question presentation screen, questions may be arranged in descending order of priority. In the above embodiment, the priority is presented as the urgency on the problem presentation screen. However, when an incentive (for example, points) is given to the respondent who made the answer, the incentive given according to the priority is given. The amount of incentives given may be specified for each problem. Also in these examples, it is possible to present to the respondent the problem posted with higher priority as the accuracy of the search result is lower.
