  FIG. 5 is a diagram illustrating an example of the contents of the learning subject DB 121. In the learning subject DB 121, the learning subject is registered in association with an ID for identifying the learning subject. The learning subject is classified by the learning subject having the same concept, superordinate concept or subordinate concept. Furthermore, in the classification, a distinction is made between a representative learning subject (referred to as “control word”) and another learning subject (referred to as “reference word”). For example, in the example of FIG. 5, “flight attendant”, “cabin attendant”, “cabin crew”, “stewardess”, and “steward” are classified into one category, and “flight attendant” is defined as a controlled word of this category. In addition, “cabin attendant”, “cabin crew”, “stewardess”, and “steward” are defined as reference words of this classification. As a controlled word, a learning subject that is considered to be the most general concept in the classification or a learning subject that is most commonly used can be determined, but can also be determined according to other criteria.

  In the learning subject DB 121, a control ID is assigned for each classification, and an individual ID is assigned for each learning subject included in the classification. In other words, the learning subject can be identified based on the control ID and the individual ID. Further, a controlled word and a reference word are defined as data types, “00” is assigned as an individual ID for controlled words, and serial numbers starting from “01” are assigned as individual IDs for reference words.

  FIG. 6 is a diagram illustrating an example of the contents of the bibliographic DB 122. Bibliographic information related to books is registered in the bibliographic DB 122 for each bibliographic ID. Bibliographic information includes ISBN (International Standard Book Number), title, content introduction, children's content introduction, author, publisher, date of publication, form, genre name, price, language, usage target, subject Publish country, out-of-print information, library collection rate, etc. are registered. As for the learning subject, kanji notation and kana notation and a page describing the learning subject are registered. The learning subject whose page is “0” indicates that it is described in the entire book. In the example of FIG. 6, it is shown that the learning subject “biography” is described across all pages, and the learning subject “Himiko” is described from 12th page to 15th page. As the out-of-print information, “1” is registered when the book is out of print, and “0” is registered when the book is not out of print. As the library collection rate, the ratio of the library that stores the book among all public libraries and school libraries (for example, all in Japan) is registered.

  In the textbook compliant material DB, explanations are registered for each learning subject. Specifically, a control ID and an individual ID for identifying a learning subject and an explanation sentence are registered in association with each other.

  The interface unit 13 performs data conversion and the like when performing communication between the server device 1 and the browsing terminal 2.

  The control unit 11 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. And the control part 11 as a computer reads the program memorize | stored in the memory | storage part 12, and performs the book search process etc. which are mentioned later. The control unit 11 functions as a keyword acquisition unit, a first extraction unit, a second extraction unit, and a presentation data generation unit.

[3. Configuration of browsing terminal 2]
Next, the configuration of the browsing terminal 2 will be described with reference to FIG. FIG. 7 is a block diagram showing a schematic configuration of the browsing terminal 2. The browsing terminal 2 includes a control unit 21, a storage unit 22, an interface unit 23, a display unit 24, and an operation unit 25.

  The storage unit 22 includes, for example, a hard disk drive, a nonvolatile memory, and the like, and stores various programs such as an operating system and application programs. In particular, an application program for displaying a digital textbook (hereinafter referred to as “textbook application”) is installed in the storage unit 12 of the present embodiment. Note that the various programs may be, for example, acquired from various server devices via a network and recorded in the storage unit 22, or the various programs recorded on a recording medium such as a DVD-ROM may be optically recorded. It may be read by a drive and recorded in the storage unit 22.

  The storage unit 22 stores digital textbooks and various data for displaying the digital textbooks. Similar to the program, these data may be acquired from another server device or the like via a network, or may be recorded on a recording medium and read via an external drive device.

  The interface unit 23 performs data conversion when performing communication between the browsing terminal 2 and the server device 1.

  The display unit 24 is configured by, for example, a liquid crystal display or the like, and a textbook selection screen (not shown) for the student U to select a digital textbook, a textbook screen (see FIG. 2) for displaying the selected digital textbook, A learning subject screen 400 (see FIG. 3) or the like is displayed. In addition, the operation unit 25 includes, for example, a button or the like, receives an operation of the student U, and transmits an operation signal indicating the operation content to the control unit 21.

  When the textbook application is activated based on the operation of the student U, the control unit 21 first causes the display unit 24 to display a textbook selection screen for displaying a list of digital textbooks stored in the storage unit 22. When any digital textbook is selected by the student U on the textbook selection screen, the control section 21 causes the display section 24 to display the selected digital textbook. Thereafter, the control unit 21 switches pages each time a page break operation by the student U is detected via the operation unit 25.

  Among the learning subjects included in the text 301 of the digital textbook, the learning subject to which the links 302a and 302b are attached has an address indicating the location of the server device 1 on the network NW as the link information and the learning subject. The attached control ID and individual ID, and the target grade of the digital textbook are embedded.

  When the learning subject to which the links 302a and 302b are stretched is selected by the student U, the control unit 21 refers to the link information embedded with respect to the selected learning subject, and controls the server device 1 with the control ID and the individual ID. A search request including the ID and information indicating the target grade of the digital textbook is transmitted. Further, the control unit 21 causes the display unit 24 to display the learning subject screen 400 based on the search result data returned from the server device 1 in response to the search request.

[4. Link embedding process]
Next, a link embedding process by a link embedding device (not shown) will be described with reference to FIG. FIG. 8 is a flowchart of the link embedding process. The link embedding process is a process for embedding a link to a learning subject in a digital textbook document, and will be described here to help the book search system S understand.

  First, the link embedding device accesses the learning subject DB 121 and acquires one record (step S11). Next, the link embedding device searches the text of the digital textbook that is the target of embedding the link for the learning subject in the acquired record (step S12).

  Next, the link embedding device determines whether or not a hit is found as a result of the full text search in the process of step S12 (step S13). At this time, if the link embedding device determines that it has been hit (learning subject is described) (step S13: YES), it creates link information and embeds the link in the hit learning subject in the document. (Step S14), the process proceeds to Step S15. On the other hand, if the link embedding device determines that no hit has occurred (no learning subject is described) (step S13: NO), the link embedding device proceeds to the process of step S15.

  Next, the link embedding device determines whether or not all records registered in the learning subject DB 121 have been acquired (step S15). At this time, if the link embedding device determines that all cases have been acquired (step S15: YES), the process shown in the flowchart is terminated. On the other hand, if it is determined that the link embedding device has not acquired all records (step S15: NO), the process proceeds to step S11, and thereafter, all records registered in the learning subject DB 121 are acquired. Steps S11 to S15 are repeated.

[5. Book search process]
Next, the book search process by the book search system S will be described with reference to FIG. FIG. 9 is a flowchart of the book search process. Note that the flowchart shown in FIG. 9 starts when the textbook application is activated on the browsing terminal 2 and any digital textbook is displayed.

  The control unit 21 of the browsing terminal 2 waits until a learning subject linked by the student U is selected or an end operation for closing the digital textbook is detected (step S31A: NO, step S35A). : NO). When the control unit 21 determines that the learning subject with the link is selected (step S31A: YES), the control unit 21 refers to the link information embedded with respect to the selected learning subject, On the other hand, a search request including the control ID and individual ID and information indicating the target grade of the digital textbook displayed on the display unit 24 is transmitted (step S32A).

  On the other hand, the control unit 11 of the server device 1 stands by until a search request is received (step S31B: NO). When the search request is received (step S31B: YES), the textbook conforming material DB is referred to. Based on the control ID and the individual ID included in the search request, a comment is acquired (step S32B).

  Next, the control unit 11 performs a first extraction process (step S33B).

  Here, the first extraction process will be described with reference to FIG. FIG. 10 is a flowchart of the first extraction process.

  First, the control unit 11 refers to the learning subject DB 121 and the bibliographic DB 122 and extracts a book based on the controlled word corresponding to the controlled ID included in the search request (step S51). Specifically, the control unit 11 refers to the learning subject DB 121 to acquire a reference word belonging to the same category as the controlled word, and then refers to the bibliographic DB 122 to determine whether the controlled word or the acquired reference word is the bibliographic information. Extract books included in the subject of learning. For example, when the control word is “flight attendant”, the control unit 11 registers “flight attendant”, “cabin attendant”, “cabin crew”, “stewardess”, and “steward” as the learning subject of bibliographic information. The books that are being extracted.

  Next, the control unit 11 refers to the bibliographic DB 122 and extracts a book in which the target grade included in the search request matches the usage target of the bibliographic information (step S52). In the process of step S52, books satisfying the extraction condition for the target grade are extracted from the books extracted in the process of step S51.

  Next, the control unit 11 refers to the bibliographic DB 122 to extract a book whose out-of-print information is “0” (that is, a book that is not out of print) (step S53), and ends the first extraction process. In the process of step S53, a book that is not out of print is extracted from the books extracted in the process of step S52.

  In this way, in the first extraction process, books that are described with respect to the learning subject designated by the student U and that are suitable for the age of the student U and are not out of print are extracted. In the first extraction process, a book in which a description related to the learning subject designated by the student U is extracted, and at least one of the process in step S52 and the process in step S53 is not performed. You can also

  Returning to FIG. 9, the control unit 11 performs the second extraction process (step S34B).

  Here, the second extraction process will be described with reference to FIG. FIG. 11 is a flowchart of the second extraction process.

  First, the control unit 11 refers to the bibliographic DB 122 and extracts a book with the newest publication date from among the books extracted by the first extraction process (step S71).

  Next, the control unit 11 refers to the bibliographic DB 122 and extracts a book having the largest number of pages described regarding the learning subject (control word or reference word) from among the books extracted in the first extraction process. (Step S72).

  Next, the control unit 11 refers to the bibliographic DB 122 and extracts a book having the highest library collection rate from among the books extracted by the first extraction process (step S73), and ends the second extraction process. .

  Returning to FIG. 9, the control part 11 produces | generates search result data, and transmits to the browsing terminal 2 (step S35B). In the search result data, the explanation sentence acquired in the process of step S32B and the title, author, publisher, and learning subject of the three books extracted in each process of step S71, step S72, and step S73 are described. Information indicating the current page is included. At this time, in the search result data, any book is the book with the newest publication date, and any book is the book with the largest number of pages described with respect to the learning subject (control word or reference word). Each of which contains information indicating whether or not the book with the highest library collection rate.

  On the other hand, the control unit 21 of the browsing terminal 2 waits until the search result data is received after the process of step S32A (step S33A: NO), and receives the search result data (step S33A: YES). The learning subject screen 400 is displayed on the display unit 24 on the basis of the explanatory text included in the search result data and the information indicating the page describing the title, author, publisher, and learning subject of the three books ( Step S34A). When the control unit 11 finishes the process of step S34A, the process proceeds to the process of step S35A, and when it is determined that the end operation has been performed (step S35A: YES), the process shown in the flowchart ends.

  As described above, the server device 1 (an example of a “book extracting device”) according to the present embodiment is a device that extracts a book in which a description related to a learning subject (an example of a “learning keyword”) that is a learning target is made. Then, the control unit 11 (an example of “keyword acquisition means” and “first extraction means”) is included in a text of a digital textbook (an example of “text data”) including a learning subject described in any book. Storage unit 12 (an example of “storage means”) that acquires the learning subject designated by the student U (an example of “user”) and stores the learning subject described in the book in association with each book. Refer to and extract a book associated with the acquired learning subject.

  Therefore, according to the server apparatus 1, a book describing the learning subject is extracted simply by the student U specifying the learning subject from the text of the digital textbook. That is, the student U can check the learning subject designated by himself / herself by confirming the book extracted by designating the learning subject. Since the learning subject selected by the student U is always described in any book, the book is not extracted (that is, the search result is 0), and the book is always extracted.

  In addition, the storage unit 12 of the server device 1 stores bibliographic information (an example of “book information”) relating to a book in association with each book, and stores the control unit 11 (“second extraction unit”, “presentation data generation unit”). An example) refers to the storage unit 12, further extracts a book for each of a plurality of different extraction conditions from the books extracted by the first extraction process, and extracts the book extracted for each extraction condition for each extraction condition. Search result data (an example of “presentation data”) to be presented to the student U is generated.

  Therefore, according to the server device 1, since the book is described with respect to the learning subject and is extracted for each of a plurality of different extraction conditions, the student U is suitable for himself. Books extracted under various extraction conditions can be confirmed.

  Furthermore, the storage unit 12 of the server device 1 stores a page (an example of “description partial information indicating a part in which a description about a learning keyword is described)” in which a description related to a learning subject in a book is made, associated with each book. Then, the control unit 11 refers to the storage unit 12 and generates search result data including information for presenting a page in which the learning subject is described for each book extracted in the second extraction process.

  Therefore, according to the server apparatus 1, a page in which a description about the learning subject is made for each extracted book is presented, and the student U immediately finds a page in which the learning subject in the extracted book is described. Can learn about the subject of study in a short time.

  Furthermore, in a plurality of different extraction conditions for extracting a book to be displayed on the learning subject screen 400, the ranking when arranging in descending order from the description amount related to the learning subject designated by the student U is ranked first (“ A book that is “an example of“ above a predetermined rank ””, a book that is ranked first (an example of “above a predetermined rank”) when the publications are arranged in order from the newest, or a library collection It includes a condition that the book has a first rank (an example of “predetermined rank or higher”) when arranged in order from a higher rate (an example of “collection rate”).

  Therefore, according to the server apparatus 1, the book suitable for the student U to learn about a learning subject can be shown. That is, the student U can ascertain a book extracted under an extraction condition suitable for himself / herself from books with a large amount of description relating to the learning subject, new books to be published, or books with a high library collection rate.

  Furthermore, the storage unit 12 of the server device 1 stores the usage target related to the target age of the book (an example of “target age information”) and the out-of-print information related to the out-of-print of the book in association with each book. A book linked to the learning subject designated by the student U with reference to the storage unit 12, a book that matches the target age of the student U, and a book that is not out of print. Books that satisfy the condition are extracted.

  Accordingly, books suitable for the target age of the student U and books that are not out of print are extracted, so that the user can check books suitable for his / her age and readily available books. If the student U uses the book search site to search for a learning subject as a keyword, a book unsuitable for the age of the student U or an out-of-printed book is detected. Books are searched, but such books are not searched in the server device 1 of the present embodiment.

  Furthermore, the control unit 11 of the server device 1 extracts a book in which a description related to a learning subject that is the same concept, a higher concept, or a lower concept is made with respect to the learning subject specified by the student U.

  Therefore, according to the server device 1, not only a book in which a description about the same learning subject as the learning subject specified by the student U is made but also a higher concept or a lower concept with respect to the learning subject specified by the student U. Books with descriptions related to the learning subject can also be extracted. For example, when the learning subject specified by the student U is “Flight Attendant”, not only the book that describes “Flight Attendant” but also “Cabin Attendant”, “Flight Attendant”, “Stewardess”, Books with descriptions related to “stewards” are also extracted.

  Furthermore, when the learning subject in the text of the digital textbook is selected by the student U, the browsing terminal 2 transmits a search request related to the learning subject to the server device 1 and receives search result data for the search request. The learning subject screen 400 is displayed. That is, the digital textbook functions as a search condition input interface for searching for books related to the learning subject.

[6. Modified example]
Next, a modification of the above embodiment will be described. Note that the modifications described below can be used in appropriate combination.

[6.1. Modification 1]
In the above embodiment, the digital textbook is stored in advance in the storage unit 22 of the browsing terminal 2, but instead, the digital textbook is stored in the server device 1 or other server device, and the student U However, it is good also as a structure which the browsing terminal 2 acquires from a server apparatus each time when using a digital textbook. This is a modification using so-called cloud computing. Also according to the modified example, the same effect as the above embodiment can be obtained.

[6.2. Modification 2]
In the said embodiment, although the control part 11 of the server apparatus 1 was set as the structure which performs the process which searches (extracts) a book, it is good also as a structure which the control part 21 of the browsing terminal 2 performs a search process instead. In the modified example, each time a book search process is performed, the learning subject DB 121, the bibliographic DB 122, and the textbook compliant material DB constructed in the storage unit 12 of the server device 1 may be accessed. The learning subject DB 121, the bibliographic DB 122, and the textbook compliant material DB may be constructed in the storage unit 22 of the browsing terminal 2 and used. In the latter case, the entire DB may be built in the storage unit 22, but the bibliographic DB 122 is a bibliographic information of a book in which the grade of the student U who uses the digital textbook matches the usage target registered as the bibliographic information. By constructing the bibliographic DB 122 from which only the information is extracted, the amount of use of the storage unit 22 can be saved. Further, when each DB is constructed in the storage unit 22 of the browsing terminal 2, the update of the DB is not necessarily a real-time update, and is periodically updated (for example, synchronized with a DB constructed in the server device). Update). In addition, the control part 21 of the browsing terminal 2 in the said modification functions as a keyword acquisition means, a 1st extraction means, a 2nd extraction means, and a presentation data generation means.

[6.3. Modification 3]
In the above embodiment, the bibliographic information of all books is registered in the bibliographic DB 122 without being limited by the grade of use, and the same bibliographic DB 122 is referred to even if a search request is received from a digital textbook of any grade. However, instead of this, the bibliographic DB 122 may be divided according to the object of use, and the bibliographic DB 122 may be selectively used according to the grade of use of the digital textbook that is the source of the search request. . For example, an extracted bibliographic DB for first graders that extracts only bibliographic information whose first target is the first grader from the bibliographic database 122, and an extracted bibliographic DB for sixth graders that extracts only bibliographic information whose first target is the sixth grade In addition, an extracted bibliographic database is created according to the usage target. In the case of the modification, the control unit 11 of the server device 1 refers to the extracted bibliographic database corresponding to the target grade included in the search request (for example, the target grade included in the search request is a first grader). In this case, refer to the extracted bibliographic DB for first graders), and perform the processing of step S51 and step S53 in FIG. According to this modified example, every time a search request is received, it is not necessary to search all bibliographic information registered in the bibliographic DB 122, so that the processing time can be shortened.

[6.4. Modification 4]
In the above-described embodiment, the books described about the learning subject on the learning subject screen 400, each of which is the most recently published book, the book with the largest amount of description related to the learning subject, and the book with the highest library collection rate. However, instead of this, at least one of these books may be displayed.

  In addition, books with a predetermined rank or higher when the publications are arranged in order from the newest (for example, top three books), books with a predetermined rank or higher when arranged in descending order of the description amount related to the learning subject (for example, , The top 3 books), and books arranged in order from the one with the highest library collection rate (for example, the top 3 books) may be displayed. In the case of the modification, the control unit 11 of the server device 1 extracts books that are higher than a predetermined rank (for example, higher than the third rank) in each process from step S71 to step S73.

  Furthermore, as shown in FIG. 12, “display more” buttons 403 a, 403 b, and 403 c are provided for each book displayed in the book display area 402 of the learning subject screen 400. When the button is selected, another book extracted according to the extraction condition corresponding to the “display more” button may be displayed. In the case of the modification, the control unit 21 of the browsing terminal 2 transmits information indicating the extraction condition corresponding to the “display more” button selected by the student U to the server device 1, and The control unit 11 extracts books corresponding to the extraction conditions and returns the list to the browsing terminal 2. According to the modified example, the student U can select a suitable book from a list of books extracted under an extraction condition suitable for him.

  Furthermore, when the book displayed in the book display area 402 is converted into an electronic book, an “electronic book” button with a link to the book converted into an electronic book is provided, When the “” button is selected, the control unit 21 may display an electronic book corresponding to the “electronic book” button. According to this modification, the student U can check the book displayed in the book display area 402 without going to the library to search for the book. In addition, when the “electronic book” button is selected and the electronic book is displayed, the control unit 21 may be configured to display a page describing the learning subject from the beginning. In this case, the student U can save the trouble of searching for the corresponding page in which the learning subject is described by changing the page, and can immediately check the learning subject.

  Furthermore, a “Purchase” button is provided for each book displayed in the book display area 402, and when the “Purchase” button is selected by the student U, the control unit 21 activates the web browser and performs the “Purchase”. You may comprise so that the applicable page of the book sales site which sells the book corresponding to a button may be displayed. According to the modification, the student U can easily purchase the book displayed in the book display area 402 from the book sales site, and can confirm the book.

  Furthermore, the learning subject screen 400 may be configured to display images, moving images, animations, and the like related to the learning subject. In this modification, for example, images, movies, animations, etc. related to the learning subject are registered in the textbook compliant material DB together with the explanation texts, and the control unit 11 performs images, movies, animations, etc. together with the explanation sentences in the process of step S32B. To get. Further, for each book displayed in the book display area 402, an image representing the book shadow of the book may be displayed. In this modification, for example, when an image representing a shadow is registered as the bibliographic information in the bibliographic DB 122 and the control unit 11 generates search result data in the process of step S35B, each process of step S71 to step S73 is performed. The image representing the shadow of the book extracted in step S1 is acquired, included in the search result data, and transmitted to the browsing terminal 2.

[6.5. Modification 5]
In the above embodiment, a book with a high library collection rate (an example of “collection rate”) is displayed in the book display area 402. However, instead of or in addition to the library collection rate, the book is owned by a company or an individual. It is good also as a structure using the collection rate (or the number of books sold for calculating the said collection rate) containing.
