It is apparent that the present invention is not limited to the description of the embodiments described below, and various modifications may be made without departing from the technical gist of the present invention. In describing the embodiments, descriptions of technical contents which are widely known in the technical field to which the present invention belongs and are not directly related to the technical gist of the present invention will be omitted.

On the other hand, the same components in the accompanying drawings are represented by the same reference numerals. In the accompanying drawings, some components may be exaggerated, omitted, or schematically illustrated. This is to clarify the gist of the present invention by omitting unnecessary description that is not related to the gist of the present invention. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating an example in which a client terminal 20 and a service server 10 according to an embodiment of the present invention transmit and receive information and provide education contents.

In step 105, the service server may collect a variety of problems and services newly created for the service and construct a problem database by structuring it in a form suitable for analysis. The problem data includes a listening assessment problem and may be in the form of text, image, audio, and / or video.

More specifically, in step 105, the service server may collect problem data and / or answers included in a published or distributed problem or a previous problem in a form that can be recognized by a computer such as a text or an image and store problem data. Problem data may be collected individually or collected using the Internet.

The service server can then group the problem data into one or more categories and index the group information into the problem to build a database. In this case, the service server may create metadata about the group information and / or indexing information, and the metadata may be managed together with the respective problem data. In addition, the metadata may include a QR code for a specific problem.

For example, the service server may manage metadata of any problem data, such as the name of the problem book containing the problem, the ISBN code of the problem book, the year of publication, the version, and the page. . Alternatively, for any past questions, information such as the institution or school in which the question is raised, the name of the test, the time of the question, the question number, etc. may be managed as metadata. The metadata may be utilized as index information for the problem.

According to another embodiment of the present invention, the service server may group each problem into various categories such as subject, related grade, subject, type, and difficulty, and index the group information. In addition, the service server can classify information contained in one problem data into options of fingerprint / problem / multiple choice problem (view) / fingerprint commentary / problem commentary / answer, etc. You can also manage topics separately.

For example, a service server is a question C on page B of a workbook called A, a question for E subjects for students in grade D, a topic for F, and a problem type If it is classified as memorized type (G), and grade D students are classified as difficulty H, information of A, B, C, D, E, F, G, H (D) can be recorded as metadata of the problem. have.

Furthermore, for the categories such as namebook, page, question number, grade, subject, type, and difficulty, the problem is classified as belonging to group A, B, C, D, E, F, G (D), and the classification information. Can be indexed to the problem. According to an embodiment of the present invention, the classification information may include relevance or similarity to other problems. The relevance may be calculated in various ways, and details of the relevance calculation method will be described later with reference to the accompanying drawings.

Furthermore, according to an embodiment of the present invention, if any problem consists of fingerprint a, examples b1, b2, b3, b4, fingerprint comment c, example comment d, the service server may structure the problem in each configuration. have. That is, the problem can be recognized as a combination of each of (a, b1, b2, b3, b4, c, d). If the subjects for views b1, b2, b3, and b4 are for f1, f2, f3, and f4, respectively, manage b1 to b4 with f1 to f4, and manage the subject of the problem f1 + f2 + f3 +. f4 can be recorded separately in the metadata of the problem.

For example, the service server 10 collects problem data in step 105, generates metadata for each problem, and structure and structure information constituting each problem into a fingerprint, view, fingerprint commentary, view commentary, and the like. You can group a problem into multiple categories and index the group information into the problem.

Meanwhile, in step 108, the client terminal 20 may install and execute a computer program according to an embodiment of the present invention. The client terminal may be an electronic device such as a mobile phone, a tablet PC, a desktop, a notebook, and the like.

Further, the computer program may be an application that runs on a mobile terminal, or may be an extension program installed in a web browsing tool of a desktop in the form of a plug-in, activex, or the like. The computer program may be downloaded and installed by the client terminal 20 through the service server 10 or the open market according to an embodiment of the present invention.

The computer program may perform a series of processes at the client terminal 20 to configure an incorrect note, to provide customized training content by using the incorrect note, and to configure a user interface for utilizing the incorrect note. A more detailed description of the function of the application will be described later.

In the example of FIG. 1, steps 110 to 140 are examples of a series of processes for constructing an incorrect note in a client terminal.

According to an embodiment of the present invention, the client terminal 20 downloads a problem stored in the problem database from the service server 10 using the problem search function, or a text image directly input by using a direct input function or a problem image taken by the camera of the mobile terminal. You can construct an incorrect note, for example, by processing an image.

For example, in step 110, the client terminal may request a problem from the service server, receive problem data in step 120, and configure an incorrect answer note in step 140.

More specifically, in step 110, a user may input a search word to search for a specific problem by the client terminal and / or the service server, and the client terminal may request the problem from the service server.

For example, a user may select Import a question from a question input menu for constructing an incorrect note, and input a question book name, an ISBN code and / or page number as the search information. In this case, the client terminal may improve the convenience of the search by displaying the name of the problem book, the test name, and the like, which the user searches in the past.

The user can also search for past questions. For example, a user may search for questions by entering information such as a test name, a test school, or an institution, a test year, a test date, and / or a subject.

Thereafter, the client terminal receives and displays a problem corresponding to the search word from the service server, and the user may select a desired problem among the displayed problems and store it in the incorrect answer note. (Step 120) If a search result is not provided at each step of the search, for example, a match to the search request problem book name does not exist in the problem database on the service server, or the search request page does not exist or the user on that page. If the desired problem number does not exist, the user can directly enter the problem using the direct input function.

According to an embodiment of the present invention, the search information may include text or an image constituting a part of a problem, as well as a problem book name and a page number. Further, the search information may be in the form of text, image, audio and / or QR code pre-matched to a specific problem.

For example, if a user inputs natural language such as grade, subject, subject, or problem type as search information, the client terminal and / or service server displays the problem with a high probability of searching based on the search term using the user's search history. In addition, the user may rescan to construct an incorrect note.

Meanwhile, as another example of configuring an incorrect note, a direct input function may be provided. In operation 130, the client terminal may receive a user input for directly inputting a problem to construct an incorrect note. If the user's problem input is an image, the client terminal may go through a processing step of processing the input image. (Step 135)

For example, according to an embodiment of the present invention, a user may select an image or text input option from a problem input menu for constructing an incorrect note.

When the user selects a problem scan as an image input, the client terminal uses the camera function to capture a problem, correct the captured image in a form suitable for problem recognition, and extract the problem image by recognizing the problem area in the corrected image. can do. Problem area recognition may be automatically recognized by the client terminal through image processing or by receiving a user's area designation input.

According to another embodiment of the present invention, when the user selects a problem scan as an image input, the client terminal may provide pre-stored images, receive a user input for selecting a problem image from the displayed image, and correct and store the corresponding image. have. The above embodiment is for allowing a user to photograph a specific problem in advance with a camera and later input the wrong answer note.

A more detailed description of the step 135 of correcting the image is as follows.

According to an embodiment of the present invention, the client terminal may recognize an object about a problem in an input image, flatten the recognized problem object, remove elements such as unnecessary shadows on the problem object, and / or recognize the text more clearly. Corrections can be made to ensure that they are processed.

For example, when a user inputs an image of a part of a test paper, the client terminal distinguishes a problem object among various objects included in the image, flattens the cabinet by equally correcting the cabinet so that the problem object becomes a rectangle or a square, and the problem Unnecessary elements such as shadows can be removed from the object, and / or the shading ratio can be adjusted and processed to store the text more clearly.

Meanwhile, according to another embodiment of the present invention, the user may search for a problem by scanning a QR code for a specific problem. In this case, the client terminal may interpret the scanned QR code to restore the problem, or access the service server and receive a problem designated by the QR code.

The image input using the direct input function may be stored in the incorrect answer note as the image itself, but according to another embodiment of the present invention, the client terminal converts the problem object of the image into OCR (Optical Character Reading) and converts it into text. It may be.

Furthermore, since OCR recognition may not be 100% perfect, in order to compensate for this, the client terminal transmits all or part of the OCR-processed text to the service server 10 and searches whether the same or similar problem exists in the problem database. You can also provide the user with accurate problem data.

Furthermore, the correct answer or comment on the question entered by the user can be stored through individual user input, and the method is the same as the problem input. Furthermore, according to another embodiment of the present invention, for the user's convenience, A, B, C, D, E, or 1, 2, 3, 4, 5, etc. may be provided, and the user may select the correct answer for the problem. .

As such, the client terminal may request the service server 10 to search the problem database to extract a problem recorded in the problem database, or configure an incorrect answer note as a problem input by the user. (Step 140)

In this case, the client terminal may generate a plurality of categories to configure incorrect notes for each category. The user can freely set the name of the category, for example, mathematics, English, or the second semester of 2015. Furthermore, the client terminal may provide a browsing option for sorting the problems included in the category according to a predetermined importance level and / or whether a separate storage is designated.

Meanwhile, the client terminal may provide a function for the user to individually note each of the problems of the incorrect note. For example, a user may note the text “Mid-term 2015 midterm test” for a problem or take an image of a teacher's written statement explaining the problem.

A detailed description of the user interface constituting the incorrect note will be described later with reference to FIGS. 2 to 4.

2 is an illustration of a user interface for searching a problem for constructing an incorrect note in accordance with an embodiment of the present invention.

According to an embodiment of the present invention, as described in FIG. 2, a user may search for a problem stored in a problem database of a service server by entering a problem book name in 210 and a page number in 220. Alternatively, the question of the past may be searched using the menu of 240.

The search result may be provided as 230, and the user may scroll down the display to view a plurality of questions contained on the page, and when selecting a plurality of displayed problems, the selected questions may be stored in the incorrect note. have.

3 is an illustration of a user interface for directly entering a problem to construct an incorrect answer note according to an embodiment of the present invention.

According to an embodiment of the present invention, as shown in FIG. 3, the user selects 310 icons to directly input a problem and / or commentary in the form of an image, or selects 320 icons to directly input a problem and / or commentary in the form of a text. You can enter Furthermore, an option for inputting the correct answer of the problem is provided as 330 to conveniently construct an incorrect answer note.

4 is an illustration of a user interface displaying a settings menu for managing incorrect notes according to an embodiment of the present invention.

According to an embodiment of the present invention, as shown in FIG. 4, while the problem 410 of the incorrect note is displayed, the user may call the menu object 420 by inputting a drag starting at the edge of the display.

In this case, the menu object 420 may be displayed in such a manner as to gradually advance to the center of the screen while overwriting the displayed problem 410, and the moving speed of the menu object may be adjusted to the speed of the user drag input to improve user intuitiveness.

According to an embodiment of the present invention, the menu object being called is disappeared again to the edge of the screen when the user drag input is terminated below the preset range, and is completely called when the user drag input exceeds the preset range to be activated to select the user input. Can be.

When the call ends, as shown in FIG. 4, the menu object 420 almost covers the problem object 410, and the call object 410 may become darker.

The user may add or delete his or her incorrect answer note or set a name of each incorrect note as shown in 430 using the called menu.

Returning to the description of FIG. 1 again, steps 155 to 167 of FIG. 1 are for explaining various functions provided by an application according to an embodiment of the present invention to improve learning efficiency of a user.

In step 155, the user can individually assign importance to any problem. The client terminal provides the option to change the title color of the problem according to the user-specified importance, to display a pop-up message that reminds the user only at a pre-set interval only for high-priority issues, or to sort incorrect notes by the importance level. Learning efficiency can be improved.

In step 160, the user can specify a separate archive for any problem in the incorrect note specific category. Problems designated for archiving are hidden so that problems in that category may not be displayed even if they are viewed in full. This is to allow the user to separately manage the problems that the user thinks are completed (master) among the problems stored in the incorrect note. On the other hand, the user can view the archived problem by using the problem sorting option of the category to relearn the archived problem.

Meanwhile, according to another exemplary embodiment of the present invention, even if a storage setting request for learning completion designation is received for a certain problem, the problem may not be immediately processed as a learning completion and may exist in a learning completion waiting state for a preset time. After the set time has elapsed, the user can pass the quiz to confirm whether the master provided by the client terminal can be treated as a learning completion.

* The quiz may be provided in such a way as to question the same or similar problems after a certain time, in order to ensure whether the learning is completed for the problem specified by the user as a master. If the user passes the test, the master problem can be deleted from the incorrect note.

According to an embodiment of the present invention, the quiz provided by the client terminal may be submitted using more various options. (Step 165)

The client terminal may provide a quiz about the problems included in the incorrect note. At this time, the quiz submission range can be designated by the user. For example, the user can specify the quiz submission range by individually setting the importance, difficulty, and / or period of time in which the question is entered in the wrong note.

The user's quiz results can be reflected in the title of the problem. For example, if a user misses a particular problem twice in a quiz, the client terminal may display an icon, such as 2X, in the title of the problem to provide information about the user's vulnerability.

In operation 167, the client terminal may provide a user with a push notification for reminding in an effective cycle.

Conventional studies on human memory have shown that humans begin to forget after 10 minutes of learning, 50 percent after one hour, 60 percent after eight hours, and 70 percent after one day. Is being reported. According to this, the most effective learning cycle is to repeat the review every 10 minutes, 1 day, 1 week, 1 month. In consideration of this, the present invention is characterized by providing a reminder for any problem in a manner such as a notification window according to a period set using a human forgetting cycle for any problem.

For example, if a user stores an arbitrary question in an incorrect note at any time, the client terminal may display a pop-up message reminding the problem every 10 minutes, 1 day, 1 week, or 1 month. . In this case, the reminder may be provided in the quiz format of step 165, and the client terminal may adjust the reminder cycle of the user by reflecting the quiz result. For example, if a user's test results after one month are generally not good, the user may adjust the frequency to provide a reminder earlier than one month.

According to the present invention, a reminder may be repeatedly provided for a predetermined problem using a human forgetting cycle, and a cycle adjusted by reflecting a user test result, but the user may set reminders, targets, and cycles through a setting menu. You can also set the time, format, etc. as needed. In the previous example for step 160, if the user designates a certain question as archived, i.e., learning completed, then testing for completion of learning after one day for the specified problem may be classified as a reminder function of the present invention.

In operation 155 to 165, a user interface for implementing the importance check function, the learning completion check function, and the remind function provided by the application according to the embodiment of the present invention will be described later with reference to FIGS. 5 and 6.

5 is an exemplary diagram of a user interface for setting importance for any problem in a client terminal according to an embodiment of the present invention.

According to the exemplary embodiment of the present invention as shown in FIG. 5, when any problem included in an incorrect answer note is displayed 510 on the display unit of the client terminal, when a user input 520 for dragging 510 to the right is received, You can set the importance as well.

In FIG. 5, the importance level included in 530 may be changed according to the user drag input 520. For example, as the drag input extends to the right, the importance of the 530 may be changed from level 1 to level 2 and level 3, and the level may be lowered by changing the drag direction. In this case, when the user completes the drag input, the importance level of the corresponding problem may be set to the importance level displayed at 530.

Furthermore, according to the present invention, the problem heading color of 510 may be changed along with the icon of the color and / or the importance level of the 530 according to the importance level, and the user may intuitively recognize the importance of the problem set by the user.

6 is an exemplary diagram of a user interface for setting a separate storage for any problem and providing a reminder in a client terminal according to an embodiment of the present invention.

According to the exemplary embodiment of the present invention as shown in FIG. 6, when a user input 620 dragging 610 to the left is input while any problem included in an incorrect answer note is displayed 610 on the display of the client terminal. An icon indicating whether to separately store and / or complete learning may be displayed, such as 630.

Then, when the length of the drag input of the 620 is input in the preset range (that is, if the length of the drag is long), the icon of the 630 is activated, and the 610 is changed to display only the heading, such as 640, so that the problem is waiting to be completed. It may be distinguished.

As described above, according to an embodiment of the present invention, the problem 640, which is classified as a waiting for completion of learning according to a user's designation, may be treated as having completed learning only after passing a test after a predetermined time elapses. The reminder timer may operate to measure the test time, and 650 of FIG. 6 is an icon representing a reminder timer.

On the other hand, for a problem of waiting for learning completion such as 640, the user may want to deassign. For example, if the user drags 640 to the left, an icon indicating completion of learning is displayed on the right side of 640, such as 630, and when the drag input continues, the icon becomes inactive. Is changed to be displayed together, the problem can be released from the waiting to complete the learning. In this case, the client terminal may display a message indicating that the reminder timer is initialized as a popup.

Returning to the description of FIG. 1 again, in step 150, the service server may analyze the user and store the user analysis result in the database or reflect the metadata in the problem database. In the example of FIG. 1, step 150 is shown as a separate step, but this is for convenience of description only. That is, step 150 may be always performed in a series of processes in which the client terminal generates and utilizes the incorrect note.

For example, when the client terminal searches for a specific problem in step 110 and requests a problem for generating an incorrect note, the service server analyzes the user by using information on the problem type, subject, or difficulty indexed to the problem. You can organize your data.

As another example, the service server analyzes that the user is vulnerable to the memorized problem when the type of the problem requested by the user is mostly “memorized”, or when the subject of the problem is mostly about the “tense”. It can be analyzed as vulnerable to.

As another example, the service server 10 may receive information about a test result of a plurality of users for a problem at 165 from a client terminal, and update similarity classification information of the corresponding problem by using the test results of the plurality of users. Can be.

This is because according to an embodiment of the present invention, the similarity of a problem may be calculated using the similarity of correct or incorrect pattern of a plurality of users. Specific methods for calculating similarity according to the present invention are described below in conjunction with the accompanying drawings.

As another example, the service server may collect problem data directly input by the user in step 135 and reflect the problem data in the problem database. For example, if the latest problem is not reflected in the problem database, the user will enter an incorrect note by directly inputting the image of the problem, and the service server can easily collect the problem in this way. have.

According to the above embodiment of the present invention, the user analysis data and the problem database can be updated through the interworking of the service server and the client terminal without any human action, and the more users of the corresponding service, the more sophisticated data can be collected. It has an effect.

Steps 170 to 190 of FIG. 1 relate to a function of providing a user-customized problem using user analysis data accumulated according to the use of an incorrect note application according to the present invention.

In operation 170, the client terminal may request a similar problem to the service server for any problem, and in operation 175, the client terminal may receive the similar problem and provide the same to the user.

By using the above function, the user can effectively learn the problem by solving a problem similar to the previously wrong problem (i.e., the problem recorded in the incorrect note in step 140), and the problem designated as completed (i.e., step 160). You can test whether you have mastered the problem by solving a problem similar to the problem you specify in.

To this end, the service server 10 may pre-index the similarity information by calculating the similarity between the problems accumulated in the problem database. For example, the service server 10 calculates similarity between problems using correct or incorrect patterns of a plurality of users, and thus the similarity information may be updated with high accuracy as user analysis data is accumulated.

Specific examples in which the service server calculates similarities between problems in accordance with an embodiment of the present invention are described below with reference to FIG. 7.

If there are n problems in the database, calculating the similarity for each problem pair requires n ² calculations. When the value of n is large enough, since considerable resources are required for n ² calculations, the present invention includes a configuration that applies a map-reduce method as shown in FIG. 7 to the similarity calculation. There is an effect that can effectively reduce the resources administered to the calculation.

In 710 of FIG. 7, 1, 2, 3, and 4 denote any problem of the problem database. Further, A, B, C, D, E, F, G, H is a user using an incorrect note application according to an embodiment of the present invention, O, X is the user's test results for the problem,? Expressing no test results, they can be used as input values for the similarity calculation of the 1, 2, 3, 4 problems.

The service server may convert an input value such as 710 into a matrix such as 720. Then, at 720, the test results of the users who have all the test results for any pair of problems (that is, without?) Can be extracted and the cosine similarity can be calculated and expressed as a map such as 730. (First shrink)

The first row 730 of FIG. 7 will be described as an example.

In the first row of 720 for the test results for

Problems

1 and 2, extracting only the test results of A, D, F, G, and H that solved both problems would yield (O, X, X, O, O) and (O , O, O, X, O). If we convert this to 1 for the correct answer and -1 for the wrong answer and then express it as (1, -1, -1,1,1) and (1,1,1, -1,1) matrices, the cosine similarity of the matrix Is calculated as -0.2. The first line of 730 is expressed as (1), (2, -0.2).

The map 730 of FIG. 7 is rearranged for each problem 740.

The closer the cosine similarity is to 1 at 740, the higher the similarity of the problem pairs, and the closer to -1, the lower the similarity of the problem pairs. Therefore, only cosine similarity values greater than 0 can be extracted in order of size and configured as 750. (Second reduction)

The first row of 750 of FIG. 7 means that problem 4 has the highest similarity to problem 1 and then 3 is high.

Using this, the final result of 770 can be obtained. (Third reduction)

In 770 of FIG. 7, problem 1 is similar in the order of

problems

4 and 3, problem 2 is similar to problem 5, problem 3 is similar in the order of

problems

4,1,5 and problem 4 is

problems

1, 3 and 5 Is similar in order, and problem 5 is similar in order of

problems

2,3,4.

As such, the service server may calculate the similarity between problems using correct or incorrect patterns of a plurality of users, and in the process, administers data values and calculations using a map-reduce method as illustrated in FIG. 7. Resources can be reduced efficiently.

Returning to the description of FIG. 1 again, in step 185, the client terminal may request a user-customized problem from the service server, and in step 190, the service server may use the user analysis data and the indexing information of the problem database to improve the learning effect of the user. It can provide the most escalating problem.

According to conventional research on learning effects, learning a problem that can yield 70 percent to 80 percent of the correct answers is most effective for trainees. Too much or too low of a problem can reduce motivation.

Therefore, the service server according to an embodiment of the present invention provides a problem that the user can score with a probability of 70 to 80 percent by using analysis information such as the user's vulnerability problem type, vulnerability unit, learning level of the group, and the like. can do.

The client terminal may provide a quiz with the received problem (eg, step 165), and the quiz result may be transmitted to the service server again and updated in the user analysis data. Further, the user's wrong question in the quiz may be automatically recorded in the wrong answer note. (For example, step 140)

In operation 168, the client terminal may provide a learning status of the user.

For example, the client terminal may provide information on the learning status of the user in the form of a statistical graph of the number of question views, the number of quiz submissions, and / or quiz results for any category.

According to another embodiment of the present invention, in step 168, the client terminal may provide a result of analyzing the cognitive tendency of the user. The user's cognitive disposition may be analyzed by the client through the incorrect note information, but may be provided by receiving a result analyzed by the service server.

For example, the service server may analyze the cognitive propensity of the user by using the user's search history and information on the problem type, subject, or difficulty indexed to the problem.

For example, the service server may analyze the user as vulnerable to the memorized problem if the type of problem requested by the user is mostly “memorized”, or if the subject of the problem is mostly about the “tense”. It can be analyzed as vulnerable to.

In this case, the analysis of vulnerable problem types, vulnerable units, etc. may be calculated as a relative value through comparison with other users classified into the same group, and the analysis result is provided to the user as visual data as shown in FIG. 8 to establish a learning plan. Can help.

The embodiments of the present invention disclosed in the specification and the drawings are only specific examples to easily explain the technical contents of the present invention and aid the understanding of the present invention, and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention can be carried out in addition to the embodiments disclosed herein.
