Description

Electronic Book Management Method through Knowledge System Mapping

The present invention relates to a method of managing an electronic book, and more particularly, to a method of generating a knowledge system according to various subjects, and then mapping and managing an electronic book of an ebook or the like to the generated knowledge system.

Providing customized learning contents according to learners' learning achievements, interests, and dispositions is a topic of e-learning technology.

According to the related art, in order to provide such customized learning contents, information about interests or levels of learners is collected in the learning process of each learner or in a non-learning space. Techniques for assigning metadata, etc., and then combining them properly are being developed.

By the way, these conventional models are based on the premise that learning contents are basically managed by being divided into basic units (for example, web page unit, page unit, single lecture amount, etc.) and merged as necessary. .

That is, the conventional model is optimized for the web-based e-learning technology in which the learning content is divided into web pages and single lecture units.

One of the problems of the conventional model is that in the case of books such as e-books, which are organically combined in a form in which the basic units of a plurality of learning contents are inseparable, each of them for legal and practical reasons such as copyright or copyright, copyright, etc. It is difficult to store and manage them separately by basic unit, so there is no room for application.

It is expected that learning technology using electronic media will evolve from e-learning technology based on the conventional web to e-book or evolved digital textbooks. However, there is a limit that it is difficult to efficiently manage the learning content in the learning environment through the digital textbook, and therefore, it is difficult to provide an optimized learning plan for each learner.

Another problem is that finding the best combination of customized learning contents by predetermined algorithm based on the information of the learner's interest and level of learning is superior to the curriculum created by an instructor who specializes in the subject and subject. It is hard to expect to produce results.

The present invention is to solve the problems of the prior art, an electronic form of a book through a knowledge system mapping that maps electromagnet books such as e-books, in which a plurality of unit learning contents are organically combined in an inseparable form, into a previously generated knowledge system. Its purpose is to provide management methods.

In order to achieve the above object, a method of managing an electronic book through a knowledge system mapping according to the present invention is performed in a server 10 connected to a network.

Step 110 of generating a knowledge unit for each subject;

A step 120 of establishing a knowledge system by determining a relationship between the generated knowledge units;

Step 130, extracting knowledge units which are units of learning content repeatedly appearing in relation to a specific subject by analyzing the electronic book 1;

Step 140 of mapping the analyzed knowledge units to a knowledge system that is a structure defining a relationship between a plurality of knowledge units on a corresponding subject for each subject; And

And a step 150 of reconfiguring and storing the table of contents of the electronic book 1 in a form in which the knowledge units belonging to the plurality of knowledge systems are sequentially connected using the mapping result.

According to the present invention, by mapping the electromagnet books such as e-books, which are organically combined in a non-separable form, a plurality of unit learning contents to a pre-generated knowledge system, a learning plan that meets the learning level, interests, and goals of the user. Will be able to present

Furthermore, it is possible to determine electronic books that conform to the path occupied by the learning plan presented in the relevant knowledge system. In particular, the present invention does not reconstruct learning content to generate customized content for each learner, but derives a learner's learning plan, and then determines an electronic book conforming to an optimized knowledge system, thereby arbitrarily reconfiguring the curriculum as learning content. It is possible to solve the problems of the prior art that the consistency or flow is broken.

Hereinafter, with reference to the preferred embodiments of the present invention and the accompanying drawings will be described the present invention. On the other hand, in order to clarify the present invention will be omitted that is not related to the configuration of the present invention, the same reference numerals in the drawings will be described on the assumption that they refer to the same components.

On the other hand, when any one element in the description or claims of the invention "includes" another component, unless otherwise stated, it is not limited to consisting only of the component is not interpreted, other configuration It is to be understood that the elements may further include.

Further, in the detailed description of the invention or in the claims, the elements designated as "~ means", "~ part", "~ module", and "~ block" mean a unit that processes at least one function or operation, Each of these may be implemented by software or hardware, or a combination thereof.

As shown in FIG. 1, the server 10 is connected to a plurality of learner terminals 20 through a network.

In this case, the network may be preferably an internet network, and the learner terminal 20 may access the server 10 through the network as a means for playing and displaying the electronic book 1.

Accordingly, the form of the learner terminal 20 may be an element of the related art such as a personal computer, a smartphone, a tablet, or a new type of electronic book 1 that is expected to appear in the near future such as a digital textbook. It may also be a dedicated terminal for playing the music.

The electronic book server 30 stores the books 1 in electronic form and provides them to the server 10 or the learner terminal 20 through a network. The electronic book server 30 may be in the form of an electronic library or an Internet bookstore having a database of electronic books.

The server 10 is a subject that generates and stores a knowledge system and obtains and analyzes electronic books 1 such as e-books from the electronic book server 30, and a plurality of learner terminals 20 connected through a network. You can gather more information from your interests and levels of learning.

The electronic book management method through the knowledge system mapping according to the present invention can be executed in such a server (10).

Prior to describing in detail a method of managing an electronic book through a knowledge system mapping according to the present invention, terms used in the present invention will be defined as follows.

"Electronic book (1)" means text, image, and multimedia contents are combined in a predetermined order and table of contents, and transmitted through a network or stored on a recording medium such as a flash memory or a DVD and reproduced. do.

The electronic book 1 may be reproduced in the learner terminal 20. All or at least some of the contents included in the electronic server 1 may be downloaded or stored locally in the learner terminal 20. Can be recycled. That is, some of the contents included in the electronic form of the server 1 may be provided in real time in an online state connected to a separate server 30 hosting the corresponding contents in some cases.

Meanwhile, the electronic book 1 is organically combined in a form in which a plurality of learning contents are inseparable. Combining in the form of non-separable means that even if it is authored using files stored on a page-by-page basis, it is finally encoded as a whole, or a technical technique such as DRM so that only a part of the learning contents can be separated and distributed and copied by a conventional method. Means that means are taken.

This electronic form of the book (1) includes not only the existing e-book (E-book) but also may include other evolved forms of e-book if the above definition is satisfied.

For example, digital textbooks that are currently being discussed may be included in this.

A "knowledge system" is a structure that defines the relationship between multiple units of knowledge on a topic by topic. The knowledge units belonging to each knowledge system can be represented by the graph structure according to their relationship.

2 illustrates a knowledge system on the subject of "JAVA programming".

In the knowledge system illustrated in FIG. 2, a plurality of knowledge units become nodes, and an edge connecting each node represents a relationship between nodes of both edges.

As illustrated in FIG. 2, from below, "Java web programming basics", "Java basic grammar", "JSP basic knowledge", "Java web programming beginner", "Java grammar beginner", "Database beginner", " Knowledge units with names such as "MVC pattern" and "Servlet" form a node.

The relationship between knowledge units is divided into good-for-all relationships, inclusion relationships, and equivalent relationships.

A posterior relationship is a relationship in which one of two units of knowledge precedes another, such as when prior learning of another unit of knowledge is required in order to learn one unit of knowledge.

According to the example of FIG. 2, the "JSP basic knowledge" has a relationship in which the preliminary learning should be made before the "Java web programming beginner", and the "Java web programming beginner" has a relationship preceding the "Java web programming intermediate". Is in.

The edges that connect them are marked with "base", which means their relationships.

On the other hand, "Java Web Programming Advanced" has an inclusion relationship that includes "Framework" and "Large Database."

The edges connecting them are marked with "part", which means inclusion.

The equivalent relationship is not illustrated in FIG. 2, but means that two or more units of knowledge are interchangeable with each other.

For example, "Java web programming beginner" and "Java script basics" may be equivalent relationships that are mutually replaceable because they are composed of learning content having similar contents and difficulty.

In this way, the knowledge system represents the connection of knowledge units in relation to a specific subject, and may be preferably represented by a graph structure.

This knowledge system is pre-written in each topic (eg, "Java programming", "high 1 mathematics", "C language", "world history", etc.) and is reflected whenever a new work or curriculum is created for that topic. It can also be supplemented.

Meanwhile, the knowledge system illustrated in FIG. 2 may further include a learning path factor in addition to the node representing the knowledge unit and the edge representing the connection relationship thereof.

The learning path argument is a node at the top of the knowledge system (ie has only child nodes in the graph structure, no parent nodes), and defines the nature of at least some of the learning paths from the lowest node to that node.

For example, at the top node of the graph structure illustrated in FIG. 2, there are nodes marked as "Advanced Developer", "Architects", and "Intermediate Developer", and the nodes ranging from the lowest node of the graph structure to the corresponding node-that is, the learning path factor. Each of the paths of knowledge units is a learning plan to learn to become an "advanced developer", a learning plan to learn to become an "architecture", and a learning plan to learn to become an "intermediate developer".

In this case, when the learning path factor defines a part of the path but not all, the knowledge units corresponding to the part of the path may be included in the learning plan.

These learning path factors can be divided into several types in content.

For example, it can be divided into learning objectives, learning activities, and obtaining a certificate.

As shown in FIG. 2, the top node of the graph structure is marked with "advanced developer", "architecture", "intermediate developer", and "JSP programmer", all of which correspond to "learning goals".

That is, in order to achieve the corresponding learning goal, each knowledge unit of the path from the lowest node of the knowledge system as shown in FIG. 2 to the learning path factor must be learned.

On the other hand, as shown in Figure 2, at the top node of the graph structure is marked as "Bulletin board", "Guestbook", "Chat", each corresponding to "learning activity".

Not all learners are necessarily studying Java programming to become advanced developers or architects, and some learners may simply want to code bulletin boards or guestbooks using Java.

As shown in FIG. 2, various "learning activities" may be displayed in the knowledge system, and the paths from the knowledge system to the corresponding learning activities are produced using "Java", "guestbook", and "chat window" using Java, respectively. It includes what the learner must learn to do so.

On the other hand, as shown in Figure 2, it is described as "SCJP", "OCP" in the top node of the graph structure, respectively, these correspond to "certification".

The path from the knowledge system to the corresponding "certificate" describes what the learner must learn to attain the certification.

A "knowledge unit" is a unit of learning content corresponding to a node of a knowledge system and corresponds to a subtopic related to a specific subject.

For example, if the subject of the knowledge system is "Java programming", then "Java web programming basics", "Java basic grammar", "JSP basic knowledge", "Java web programming beginner", "Java grammar beginner" There may be subtopics.

These units of knowledge emerge frequently and repeatedly through a number of works on the subject.

For example, if most Java programming books for beginners have chapters corresponding to "Java Web Programming Fundamentals" or "Java Basic Grammar," they will occupy one node in the knowledge system.

As another example, if there are units such as "statistics" and "calculus" in the majority of books on the subject of "high one mathematics," they occupy nodes as a unit of knowledge in the "high one mathematics" knowledge system. Will be.

3 is a diagram in which analysis of a plurality of knowledge units is performed to generate a knowledge system.

3 by giving a "name" to the unit of learning content that appears repeatedly based on a specific subject, describing the "content summary", and then setting the "keyword", "level", and "type" The unit of knowledge is created as shown.

The name and keywords of the unit of knowledge can be derived from the table of contents of the book (in this case, the classic form) related to the subject, and the content can be described by summarizing the content of the relevant section of the book.

The level is information that can be added to determine whether or not to meet the learning level of the learner, the type corresponds to the information that can be added to determine whether it is suitable for the learner's learning objectives.

The "learning unit" is a basic unit of learning content included in each individual knowledge unit. This unit of learning does not appear repeatedly in works related to the subject.

For example, even if there is a section corresponding to "Java web programming basics" in most Java programming books for beginners, the explanations, examples, quizzes, etc. of the sections are different for each book.

That is, the unit of learning means that the learning content included in the unit of knowledge does not appear repeatedly in works related to the subject, and thus does not occupy the position of the node in the knowledge system.

Meanwhile, "mapping" refers to a process of dividing the table of contents of the electronic book 1 into a plurality of knowledge units and selecting corresponding ones among the knowledge units belonging to the previously generated knowledge system for each knowledge unit.

In addition, the term "learning content" is used, but as a general term, it refers to data produced in the form of text, images, or other multimedia written for the purpose of learning. In the present invention, the term "unit" such as knowledge unit or learning unit is used. It is not to be used in terms of the corresponding layer.

Hereinafter, a method of managing an electronic book through a knowledge system mapping according to the present invention will be described using the terms conceptually defined as described above with reference to FIGS. 4 to 6.

4 is a reference diagram illustrating a process of generating a learning plan by extracting a part of a path in a knowledge system according to a user's interest, a learning level, or a learning goal, and managing an electronic book through a knowledge system mapping according to the present invention. The method corresponds to part of the overall process shown in FIG. 4.

As shown in FIG. 4A, first, a knowledge unit is generated through a process as illustrated in FIGS. 2 and 3, and a knowledge system is established by establishing a relationship between the generated knowledge units. .

Thereafter, as shown in (b) of FIG. 4, the available electronic forms of the books 1 are mapped to the established knowledge system.

Next, as shown in (c) of FIG. 4, information about the learner's interests, learning levels, and learning goals is collected.

As shown in FIG. 4 (d), a learning plan is generated using the knowledge system.

Finally, as shown in (e) of FIG. 4, an electronic book 1 in conformity with the learning plan is recommended.

The learner selects one or more electronic books (1) required by the student from among the recommended electronic books (1) and reads them in an integrated form.

The electronic book management method through the knowledge system mapping according to the present invention corresponds to a process of generating a knowledge system and mapping the books 1 in electronic form in FIGS. 4 (a) and 4 (b).

5 is a diagram illustrating a result of mapping a plurality of electronic books to a knowledge system, and FIG. 6 is a flowchart illustrating a method of managing an electronic book through knowledge system mapping according to the present invention.

As illustrated in FIG. 6, the server 10 generates a unit of knowledge from the table of contents of works related to a specific topic previously collected as illustrated in FIG. 3 (S110).

At this time, the works related to a particular subject include not only electronic books such as e-books, but also classic books.

On the other hand, the collection of works related to a particular subject is a process performed by the worker does not belong to the scope of the present invention.

In the case of an electronic book, the table of contents data can be retrieved, parsed and analyzed by a predetermined algorithm. In the case of a classic book, the operator converts the table of contents into an image file and then converts the table of contents again into text. Can be analyzed by algorithm.

When creating a knowledge unit, the table of contents (or sub-category) itself of the work may be used as the name of the knowledge unit, and the classification of the book (eg, "Java programming", " Java grammar "), difficulty (eg," basic "," beginner "," intermediate "), type (eg," textbook "," certificate "," practice "), respectively.

On the other hand, the worker may complement the knowledge unit generated by the server 10 to be more precise and accurate as illustrated in FIG. 3 if necessary.

Thereafter, the server 10 determines a relationship between the generated knowledge units by using a table of previously collected works related to each subject (S120).

That is, it is possible to determine whether one knowledge unit precedes another knowledge unit from the contents of previously collected works,

Alternatively, it may be determined whether one knowledge unit includes the other knowledge unit.

Alternatively, it may be determined whether one knowledge unit is equivalent to another knowledge unit.

As a result of this determination, the relationship between the knowledge units is determined.

Thereafter, as illustrated in FIG. 2, the server 10 may generate a graph structure using the generated knowledge unit as a node and an edge between the knowledge units as an edge.

As we have already seen, the generated graph structure corresponds to the knowledge system.

Meanwhile, as described above, the knowledge system further includes a learning path factor that is a node that exists at the top of the knowledge system and defines a nature of the learning path from the lowest node to the corresponding node. We analyze the commonalities of the knowledge units belonging to the path from the lowest node of each graph structure to the other nodes.

For example, if the units of knowledge that correspond to a particular path are all about "qualifications," the new node on top of that path's top node (where the top node is just the top node on a particular path, may not be the top-level structure of the graph). A node can be created to set a learning path factor with the name / attribute "certificate".

According to the example of FIG. 2, it can be seen that nodes such as "SCJP" and "OCP" exist.

Or, if the knowledge units corresponding to a particular path are related to "Java web programming," and the level of difficulty increases from the lowest level to the lowest level, then a new node is created on top of the top node of the path. You can set a learning path parameter with the name / attribute ".

According to the example of FIG. 2, it can be seen that there is a node labeled "intermediate developer" in the middle of the graph.

Through this process, a knowledge system as illustrated in FIG. 2 is established in relation to a specific subject.

This process of establishing a knowledge system can be repeated on a variety of topics.

However, such a knowledge system can be established for learning contents of a nature in which reading or learning should be performed in a predetermined order, and does not apply to books and books such as novels and essays in which there is no learning order.

A knowledge system can be established for learning content primarily related to learning.

When the knowledge system is established as described above, the server 10 analyzes the electronic book 1 obtained through the network to extract the knowledge unit (S130), and maps the established knowledge system (S140).

To this end, the server 10 reads the table of contents of the electronic book 1 in step S130 and extracts a keyword for each item of the table of contents.

In operation S140, the server 10 maps the corresponding keyword among the plurality of knowledge units belonging to the predetermined knowledge system by using the extracted keyword to determine a corresponding item among the table of contents items of the electronic book 1. .

5 is a diagram showing the results of the mapping through this process.

The order numbered 1, 2, 3, 4, 5, 6, 7, 8 on the right side of FIG. 5 refers to books 1 in electronic form on the subject of "Java programming", respectively.

In addition, "Java web programming basics", "JSP basic knowledge", "Java web programming beginners", etc. on the right mean knowledge units belonging to an established knowledge system.

On the other hand, the portion indicated by O or ▲ at the bottom of the right sequence in Fig. 5 is a result of determining whether the table of contents item of each electronic book 1 corresponds to each knowledge unit.

The part marked with O means that it is correctly mapped to a specific knowledge unit of the knowledge system, and the part marked with ▲ means that the mapping is done by the algorithm but the accuracy is lower than a certain value.

The part without any mark means no mapping.

According to the example of FIG. 5, the first electronic book 1 is mapped to "Java web programming basics", "JSP basic knowledge", "JSP web programming beginner", and "JSP web programming intermediate". ,

There is no mapping for "Java Web Programming Intermediate" and "Java Web Programming Advanced".

On the other hand, the second electronic book (1) was mapped to some of the "JSP basic knowledge", and the first electronic book (1) was not mapped to "Java Web Programming Intermediate", "Java." You can see the mapping is made in "Web programming advanced".

When the mapping of the electronic books 1 is performed through the above process, the server 10 may reconstruct and store the table of contents of each electronic book 1 into a form in which mapped knowledge units are sequentially connected. (S150).

That is, the contents of the electronic book No. 1 in electronic form (1) can be separately stored as "Java web programming basics"-> "JSP basic knowledge"-> "JSP web programming beginner"-> "JSP web programming intermediate". ,

The table of contents of electronic book 2 (1) can be stored separately: "JSP Basics"-> "Java Web Programming Intermediate"-> "Java Web Programming Advanced".

Meanwhile, the electronic book management method through the knowledge system mapping according to the present invention may be embodied as computer readable codes and stored in a computer readable recording medium.

In this case, the computer-readable recording medium may include all kinds of media storing data readable by the computer system, for example, DVD-ROM, CD-ROM, hard disk, USB memory, flash memory. Etc. can be mentioned.

On the other hand, the expression contained in the recording medium encompasses both the case of being recorded on the recording medium in large quantities and distributed in a package form as well as being provided through the network in the form of data packets and stored in the recording medium.

Although the present invention has been described with reference to the accompanying drawings and the above embodiments, these are merely exemplary and will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. . Accordingly, the scope of the present invention should be defined only by the technical spirit of the appended claims, and is not limited to the above embodiments.

The present invention can be applied to the field of learning technology using the electronic form of the medium.
