DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a book data registration method and a book data registration system according to one embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram for explaining registration and search of 1 in the electronic book database. Registration of book data in the electronic book database 1 is performed using the book data registration system 2. On the other hand, search is WW
This is performed via the W server 3. In this case, between the WWW server 3 and the terminal 4 as a client, an HTTP (Hyper
Communication is performed using a protocol called Text Transfer Protocol). Then, the terminal 4 makes a request for searching the electronic book database 1, and the WWW server 3 sends a search result described in HTML (Hyper Text Markup Language), which is a hypertext description language, as a response. The terminal 4 searches the electronic book database 1 and displays the search results using software called a browser for displaying the data described in the HTML format. Note that the search is not limited to the case where the search is performed via a WWW server, and may be performed through a general database server. Although only one book data registration system 2 and one terminal 4 are shown in FIG. 1, this is an environment in which book data registration by a plurality of book data registration systems 2 or search by a plurality of terminals 4 are performed. Is also good.

Next, the book data registration method of the present invention will be described. FIG. 2 is a flowchart showing an outline of the book data registration method of the present invention. First, the structure of a plurality of types of books is analyzed, items having the same meaning are grouped as similar items, the general structure of the book is determined, and the general structure is defined using a tag representing each item, whereby the DTD ( Determine book structure definition (step S1)
1). Then, based on the DTD defined in step S11, the structure of the book data to be registered is analyzed, and the structure information of the book data to be registered is determined (step S12). Next, based on the book data structure information determined in step S12, the book data to be registered is converted into SGML (standard description language) including book data structure information using a tag defined by the DTD in step S11 (step S11). S1
3). Here, the reason why the SGML is used is to facilitate the registration in the electronic book database 1 by once describing in a standard description format. That is, it is possible to support any database structure. Then, the SGML-converted book data is registered in the electronic book database 1 (step S14). This step S1
By repeating steps S2 to S14, book data is sequentially registered in the electronic book database 1 based on the general-purpose DTD determined in step S11. Step S
Once the DTD is determined at 11, this DTD is in principle unchanged. The above is the flow of processing in book data registration.

Next, the DTD used in the present invention will be described in detail. FIG. 3 is a diagram illustrating a framework of a general-purpose structure of a book. Note that the skeleton of the general-purpose structure of the book in FIG. 3 is determined by analyzing the contents of a plurality of types of books. 3, the book includes a bibliography 31 including items such as a bibliography name and a publication date, and further includes a plurality of articles (reference numeral 32 and the like). Further, the article is the main text (reference numeral 33).
This text is divided into chapters, sections, and sections, and it can be seen that the structure including figures, tables, and the like was analyzed as a general-purpose structure.

Although not shown in FIG. 3, in the determination of the general-purpose structure, items having different expressions but having the same meaning are grouped as similar items to determine an item representing the structure of the book. For example, “edit”, “inquiry”, and “issuer”, “FIG”, “figure”, and “figure” are such. These are not defined as different items, but as the same one item.
As an example, "Fig", "figure", and "figure" are all defined as "figure" items. In this way, by grouping items having different expressions but having the same meaning, a general-purpose book structure can be defined. Furthermore, in the book data to be registered, items having different expressions but having the same meaning do not have different item names, and search efficiency after database registration can be improved. This allows
A general-purpose DTD can be defined regardless of the field. Then, by registering the book data in the database based on the DTD, it is not necessary to manage the database for each specific field, and it is possible to search the book database regardless of the field. Note that FIG. 3 only shows the framework (outline) of the general structure of a book, and details will be described later with reference to FIG.

FIG. 4 is a diagram showing the skeleton of the DTD used in the present invention. Here, the structure of the book is represented by showing the relationship between items constituting the book for easy understanding. 4, an item "bibliography" 41 including items such as "bibliographic name" and "nominal issue date" is first defined. The structure of this item "bibliography" 41 includes "volume serial number", "number of common names", "bibliographic information", and "article" in addition to the above items.

In the item "volume serial number" 42, a symbol "?" Is added at the end of the item, which means that one or zero pieces of information of this item are included. Note that “0” means that the data corresponding to this item is not included in the book data to be registered. The item "bibliographic information" 43 is enclosed by a symbol "<>", which means that an item defining the structure of the item is separately provided. For example, in the item "bibliographic information" 43, the structure of the item is separately defined by reference numeral 45. In addition, in the item “article” 44, a symbol “+” is added at the end, which means that one or more items are included. In addition, the symbol “*” is added at the end of the item “price” indicated by reference numeral 48, which means that the item is included in zero or more. On the other hand, an item without a symbol at the end of the item means that one item is always included. To sum up the above, there is no symbol: an item that always contains one symbol “?”: An item that contains one or zero symbols “+”: an item that contains one or more symbols “*” ... Items that contain 0 or more items Concatenated by the symbol <> ... The structure of the item is defined separately. This rule is common in FIGS. 4 to 9.
Whether or not the above-mentioned symbol is attached to each item is determined in the process of analyzing a plurality of books described above.

Next, in the item 45 defining the structure of "bibliographic information", there are book numbers such as "ISBN code" 46 and "ISSN code" 47 as items included therein. These book numbers are codes uniquely assigned to each book. By providing an item for holding book-specific information such as a book number, it is possible to search the electronic book database based on these pieces of unique information. On the other hand, item 4 that defines the structure of "article"
9 includes "field title", "field subtitle", "article information", and the like as items included therein. It should be noted that "table of contents" 4
There is 0. Articles in a book are unordered, but only in this "table of contents" the order is indicated.

The correspondence between the skeleton of the DTD shown in FIG. 4 and the skeleton of the general structure of the book shown in FIG. 3 will be described. It is defined based on the item "
The article "49" is defined based on the article (reference numeral 32 and the like) in FIG.

Incidentally, a specific item may be used in the structure definition of a plurality of items. For example, the item "text" will be needed to define the structure of items such as "articles", "summary", and "footnotes", and the item "image" is not only a figure, "Cover", "
It is necessary to define the structure of items such as “back cover” and “logo.” Such items that are commonly used when defining the structure of multiple items are separately defined as “independent component items”. , Facilitate the definition of book structure. FIG. 5 is a diagram showing this independent configuration item and its structure definition. As shown in the figure, "Sentence", "Editor", "
The terms “company”, “person”, “image”, and “department” are defined.These independent configuration items are used for general purposes when defining the structure of other items.
There is also a case where the term “author” is defined as a “person”, which is generally used by reading the item name, etc. In addition, in FIG. Means that it is constituted by any of a plurality of items summarized by the symbol "or". Further, the symbol “()” that summarizes the items “nominal”, “person name”, and “role” shown by the reference numeral 52 means that these plural items constitute one unit. In the example of reference numeral 52, the items "nominal", "person name", and "role" are one unit, and the symbol "+" means that one or more units are included. This rule is common to FIGS. 4 to 9.

By the way, at the stage of analyzing the book data to be registered based on the determined DTD, there may be cases where items that cannot be surrounded by the general-purpose structure of the book defined by the DTD occur. It is necessary to provide items for classifying such items. Therefore, as shown in FIG. 6, an item “memo” is defined in order to classify a portion that cannot be handled by the standard structure. As shown in the figure, this item “memo” has a configuration including zero or more of any of the items “sentence”, “paragraph separator”, and “paragraph separator”. This item “memo” is added to items that are determined in the process of analyzing the structure of a plurality of types of books to include items that cannot be surrounded by the general-purpose structure of the book. For example, as indicated by reference numeral 53 in FIG. 5, this item “memo” is included in the structure definition of the item “image”.
Has been added. The item "memo" is added in the structure definition of other items, but they will be described separately. In this way, by providing an item “memo” for classifying items that cannot be surrounded by the general-purpose structure of a book, it is possible to classify even if an item that cannot be surrounded by the general-purpose structure of a book occurs in the registered book data. Become.

Next, in FIG. 4, the item "Bibliographic information" 4
The structure definition of the item enclosed by the symbol “<>” in the structure definition of the item 5 and the item “article” 49, that is, the structure definition of the separately defined item will be described with reference to FIGS. 7 to 9. FIG. 7 is a diagram showing a structure definition of an item whose structure is separately defined in the item "bibliographic information". FIG. 7 shows the structural definitions of the items “price”, “publisher”, “bookbinding”, “advertisement”, “appendix”, “table of contents”, and “publishing history” in the item “bibliographic information”. Further, items that are included in the structure definition of these items and are separately defined in structure, and for which the structure definition of the item has not been shown so far are also shown. For example, the item "item in binding" 78
The cover “75”, “back cover” 76, and “logo” 77 correspond to this.

In FIG. 7, the item “memo” explained in FIG. 6 is included in the structure definition of the items “price”, “bookbinding” and “publishing history” (parts indicated by reference numerals 71, 72 and 73). . These are items determined as a result of analysis of a plurality of books to include items that cannot be surrounded by the general-purpose structure of the book defined by the DTD. Also, in the item "Binding" 78,
There are items “cover”, “back cover”, and “logo”, and these items (reference numerals 75, 76, and 77) are provided for storing information specific to the book such as a cover, a back cover, and a logo image. It is. These parts are parts that have a visual impact, and by enabling such information to be classified, a multifaceted search of the electronic book database becomes possible. Also, the item “Table of Contents” 7
9 is its own item "table of contents" (reference numeral 7) in the structure definition.
4) Nested structure is included. The table of contents is generally composed of a plurality of titles and their pages, and a certain table may have a more detailed table of contents. That is, it may be a table of contents of a multi-stage configuration. When the table of contents has a plurality of levels, the number of levels varies depending on the book. Therefore, by defining in a nested structure in this way, there is no restriction on the number of repetitions, and it becomes possible to cope with a table of contents of any number of stages.

Next, FIGS. 8 and 9 are diagrams showing the structure definition of items separately defined in the item "article". FIG. 8 shows the structure definition of the items “article information” and “paragraph” in the item “article”.
The structural definitions of the items “table”, “figure”, “enclosed article”, and “reference” in the article are shown.
Items which are included in the structure definition of these items and are separately defined in structure, and for which the structure definition of the item has not been shown so far are also shown. In FIG.
The item “paragraph” 81 has an item “text” in its structure definition, and the structure of the item “text” is defined as indicated by reference numeral 82. The structure definition of the item “body” 82 includes an item “paragraph” as indicated by reference numeral 83. By defining in a nested structure in this way, there is no restriction on the number of repetitions, and it is possible to cope with a paragraph configuration having any number of columns.

Next, an example in which the DTD is defined using tags representing the items of the book structure described with reference to FIGS. 4 to 9 will be described. FIG. 10 and FIG. 11 are diagrams showing some of the definitions by tags in the DTD. Note that FIG. 11 is a continuation of FIG. 10 due to the space of the drawing. First, the meaning of the symbols used in FIGS. 10 and 11 will be described. Each symbol has no symbol… Tag (item) that is always included 1 Symbol “?”… Tag (item) that is included 1 or 0 Symbol “+”… Tag that is included 1 or more (Item) Symbol “*”... Tag (item) containing 0 or more symbols Symbol “|”... Represents OR (OR), and means a configuration with any tag (item). In addition, delimiters are associated with the symbols “<” and “>”. Hereinafter, the contents of FIGS. 10 and 11 will be described.

The line indicated by reference numeral 101 in FIG. 10 represents the document type of the DTD, and the document type is defined as "MAGAZINE". Sign 1
02, the name of this DTD is indicated as "jawme.dtd". "-<Title>????-" represents the meaning of the tag, and "????" means the tag.
Lines denoted by reference numerals 103 to 105 are tags indicating the independent configuration items in FIG. For example, it can be seen that the line denoted by reference numeral 103 is a tag relating to “sentence” from the part below “<Title>”. “ENTITY” means an independent configuration item, and the next “% text” indicates a text tag. And
The portion surrounded by the symbol "" is the structure definition of this sentence, and the tag (item) used for this structure definition is shown. Note that “(#PCDATA)” in this represents a text (character string). Also, “sub”, “sup”, “ma”
“thtxt”, “em”, “I”, and “b” represent subscripts, superscripts, mathematical expressions, emphasis, italic, and bold, respectively, and are constituted by these tags. Since the tags are connected by the symbol "|" (OR), it means that the tag is constituted by any tag.
The definition of tags such as these subscripts is, for example,
6 to 108. Please note that "
“RCDATA” means a tag for modification such as a subscript, and “ELEMENT” means a tag definition.

Then, the tag "
% EDITOR ”(editor) structure definition
The structure definition of tag "% Image" (image) is made in the line shown in. Structural definitions are similarly made for other independent configuration items. The line indicated by reference numeral 109 defines the structure of a tag “memo” for classifying items that cannot be surrounded by the general-purpose structure of the book described with reference to FIG. From the figure, this tag “memo” is replaced by “(% tex
t) ”(text),“ br ”(paragraph separator),“
p ”(paragraph separator), and the symbol“
* ”Is defined as one or more of these as one unit. The tag“ memo ”is included in the structure definition of the tag“% Image ”(image) indicated by reference numeral 105. A tag “MAGAGI” representing the item “Bibliography” described in FIG.
The structure definition of “NE” (bibliography) is made, and “name” (bibliographic name), “pubnrml” (nominal publication date) and the like are used as tags in this structure definition.
The tags “MAGINFO” (bibliographic information) and “DOCMENT” (article) defined by the lines 1 and 112 and separately defined in structure are defined by the lines 113 and 121 in FIG.

In FIG. 11, the tag "113"
“MAGINFO” (bibliographic information) is the item “bibliographic information” 4 in FIG.
5 and the tag "isbncd" (ISB
N code), "issncd" (ISSN code)
Contains a tag to hold the book's unique information.
These tags are defined by lines indicated by reference numerals 114 and 116, respectively. A tag “Pprice” (price) is defined in a line indicated by reference numeral 117. In this structure definition, a tag for classifying items that cannot be surrounded by the general structure of a book as described with reference to FIG. It is defined to include "memo". Also, this tag "MAGINF
The tag “COVER” (binding) included in “O” (bibliographic information)
The structure is defined by the line indicated by reference numeral 118, and includes tags “fcover” (cover) and “bcove” as described with reference to FIG.
Tags for storing unique information in the book, such as "r" (back cover) and "logo" (logo), are included. These are defined in lines indicated by reference numerals 118a, 118b, and the like. COVER ”
The tag includes a tag "memo" (memo) as described with reference to FIG.

A tag "CONTENTS" (table of contents) included in the tag "MAGINFO" (bibliographic information) is structurally defined by a line indicated by reference numeral 120, and includes a multi-level table of contents as described with reference to FIG. In order to respond to the tag "CO
The structure is defined as a nested structure including “NTENTS” (table of contents). In SGMLization, a tag indicating a start and a tag indicating an end are used to represent a range indicated by the tag. The symbol "-O" used in the line indicates that the tag indicating the end can be omitted, and the tag indicating the start and the tag indicating the end are shown in FIGS. Next, the tag “DOCU” indicated by reference numeral 121 will be described in detail.
MENT ”(article) corresponds to the item“ article ”49 in FIG.
The tag “PARAGRAP” (paragraph) is included in the structure definition,
The structure of this tag is defined by the line indicated by reference numeral 122. The tag “PARAGRAP” (paragraph) includes the tag “body” (text), and the structure is defined by the line indicated by reference numeral 123. The tag “body” (body) is defined as a nested structure including the tag “DOCUMENT” (article) in the structure definition. Finally, the definition of this DTD is completed by the line indicated by reference numeral 124.

The above is the DTD used in the present embodiment. The DTD analyzes 1) the structure of a plurality of books and analyzes items having the same meaning as similar items to determine the general structure of the book. 2) Classifies book data that cannot be surrounded by the general structure of the book. 3) Includes items (tags) for holding book-specific information such as book space and book numbers. 4) Nest items that require multiple rows of the same item. A DTD having features in terms of its structure and including at least one feature among them is sufficient, and is not limited to the above-described DTD.

Next, the book data registration system 2 using the above-mentioned DTD will be described in detail. FIG. 12 is a block diagram of the book data registration system 2 of the present invention. As shown in the figure, the book data registration system 2 includes a processing unit 21 that performs various data processing and a storage unit 31 that stores various data. In addition, the book data registration system 2
A display device 11 such as a CRT (Cathode Ray Tube), an input device 12 such as a keyboard and a mouse, and an output device 13 serving as an output unit when registering book data in an electronic book database are connected. Then, the processing unit 21 includes a structure information establishing unit 22 for determining structure information of the book data to be registered based on the DTD, and a DT based on the structure information of the book data.
SGML conversion unit 23 that converts the data into SGML including the structure information of the book data using the tag defined in D, SGML
And a registration processing unit 24 for registering the converted book data in the electronic book database 1. The three processing units correspond to steps S12, S13, and S13 in FIG.
This corresponds to the process of S14.

The structure information establishing unit 22 includes a book data loading unit 25 for loading book data to be registered in a processable format, a structure designation processing unit 26 for processing book data structure information, and a book structure information. A definition check processing unit 27 that determines whether or not it corresponds to the defined DTD is provided. S
The GML conversion unit 23 includes an SGML processing unit 28 that performs an SGML conversion process, and a unified processing unit 29 that performs a predetermined conversion process so as to increase the search efficiency of the registered book data.
The processing unit 21 may be realized by dedicated hardware, but may be provided as a program and executed by a CPU (Central Processing Unit) (not shown) to realize its function. Is also good.

On the other hand, the storage unit 31 stores the above-mentioned DTD information 3
2. Book data 33 to be registered, structure information establishment unit 2
2, the structure information 34 serving as the work area, and the SGML conversion unit 29
Is stored as the SGML-converted file 35 which is the output result of. The storage unit 31 stores, for example, a RAM (Random
Access Memory) or a storage device such as a hard disk.

Next, the operation of the book data registration system 2 will be described in detail with reference to the drawings. FIG. 13 is a flowchart showing the operation of the book data registration system 2. First, the book data to be registered by the book data loading unit 25 is loaded into the book data 33 of the storage unit 31 (step S21). Many current publications are DT
Edited by P (Desk Top Publishing)
Electronic book data exists. However, the data format of the book data differs depending on the DTP system.
Therefore, the book data loading unit 25 performs loading in a format that can be easily processed by the book data registration system 2.
For this reason, the book data loading unit 25 has a function of supporting various data formats of book data and loading the book data in a format that can be easily processed by the book data registration system 2. If there is no digitized book data or if a printed book must be used, the OC
Using R (Optical Character Reader) or
After digitization by key input, the book data loading unit 25
Will be loaded.

Next, the structure designation processing unit 26 allows the user to designate the structure of the loaded book data, and stores the designated information in the storage unit 31 (step S2).
2). The storage process in the storage unit 31 stores the range of the item and the structure information (item content) in pairs. In addition,
In book data created by the DTD, information indicating book structure information may be included in the data. In such a case, the structure designation processing unit 26 may present the structure information to the user of the system, and have the user check whether the structure information is appropriate, thereby reducing the burden of the user designation. In this case, the book data loading unit 25 loads the information including the structure information. Further, the structure specification processing unit 26 may perform a structure analysis of the book data in accordance with the DTD, and have the user check whether the result is appropriate.

Next, the definition check processing unit 27 checks whether the specified structure information conforms to the DTD information 32 stored in the storage unit 31 (step S2).
3). If not, an error message is displayed and the user is designated again (step S24). DTD information 3
As an example that does not conform to item 2, the item "Bibliographic information" in FIG.
The item “ISBN code” 46 in 45 is defined as including one or zero items.
If the second ISBN code is specified, an error will occur. Thus, the structure information according to the definition of the DTD is sequentially stored in the storage unit 31.

Then, the structure information establishing unit 22 determines whether or not all the specification of the structure information of the electronic data to be registered has been completed (step S25). When the specification has been completed, the process proceeds to the next processing. The determination of the end is made based on an instruction from the user or whether or not the structure information has been specified for all parts of the book data. Next, the SGML processing unit 28 converts the book data 33 into SGML using the format information 34 and stores the SGML file 35 in the storage unit 35.
(Step S26). FIGS. 14 and 15 show an example of a file converted to SGML by this processing. Note that FIG. 15 is a continuation of FIG. 14 due to the space of the drawing.

First, the meaning of the symbols used in FIGS. 14 and 15 will be described. In the figure, characters surrounded by “<>” indicate the tags described with reference to FIGS. Assuming that the tag name is "A", the range from "<A>" to "</A>" indicates the range from the beginning to the end of the meaning of the tag. That is, “<A>”
Is a tag meaning start, and "</A>" is a tag meaning end. Hereinafter, the contents of FIGS. 14 and 15 will be described. The line indicated by reference numeral 141 in FIG. 14 indicates the document type and describes that the above-described DTD is used. Then, the tag “142”
<MAGAGINE> “(bibliography) indicates 174 shown in FIG.
</ MAGAGINE> ”represents the entire bibliography. In the bibliography,“ name ”(bibliographic name) indicated by reference numeral 143 and“ pubnrml ”indicated by reference numeral 144
(Nominal issue date), “MAGINFO” (bibliographic information) shown by reference numerals 145 to 163, “DOCUMENT” (article) shown by reference numerals 164 to 173, and the like. Also, the bibliographic name is “NTT BUSINESS” from the line indicated by reference numeral 143.
It turns out that it is. In addition, the contents can be understood from the range indicated by each tag.

As the bibliographic information, reference numeral 14 in FIG.
"Pprice" (price) shown from 6 to 149, "COVER" (bookbinding) shown from 150 to 155, and 15 shown in FIG.
It can be seen that “CONTENTS” (table of contents) and the like shown in Nos. 6 to 162 are included. The tag “memo” (memo) is included in “Pprice” (price) from the portion indicated by reference numeral 148 in FIG.
Includes “excluding tax”. Also, “COVER”
In the (bookbinding), there are "fcover" (cover), which is the unique information of the book, in the portions indicated by reference numerals 151 to 154, and "file" (fill name) indicated by reference numeral 152 therein.
And “filesize” (file size) indicated by reference numeral 153. Also, “CONTENTS” in FIG.
In the (table of contents), "field" (field title) indicated by reference numeral 157, and "title" (title) and "pag"
e "(page) as a set of two pieces of information (reference numerals 158 and 1).
59 sets and reference numerals 160 and 161).

As an article, "fiel" shown by reference numeral 165
d ”(field title),“ D ”indicated by reference numerals 166 to 169
OCINFO "(article information), indicated by reference numerals 170 to 172"
PARAGRAP ”(paragraphs), etc. The order of each article is associated with the table of contents, but reference numbers 157 and 165, reference numbers 158 and 167, and reference numbers 159 and 168 It can be seen that they are associated with each other in the “PARAGRAP” (paragraph).
As shown in FIG. 1, "body" (text) is included. In the examples of FIGS. 14 and 15, a plurality of articles are one SGM.
Although stored in an L file, it is preferable to create an SGML file for each article. This is because, even if the books have different publication dates, there may be a series of articles in the books. In such a case, the SGML file is used for each article, so that it becomes easy to associate each related article. In addition, since the search target is generally an article, the creation of an SGML file for each article makes it easy to extract only the article. Note that, in this case, the articles that have fallen apart are associated only by the table of contents information included in the SGML file.

Next, a process of unifying the registered book data into a predetermined format is performed by the unification processing unit 28 so as to increase the search efficiency of the registered book data (step S27). Here, the unifying process is any one of 1) conversion of a predetermined pronoun to an item indicated by the pronoun 2) replacement of a reference target from page information to link information 3) conversion of date information to a predetermined date information display format It refers to one or more processes.

The conversion of a given pronoun into a matter indicated by the pronoun means, for example, replacing "booklet" and "booklet" appearing in the text with the bibliographic name or article name indicated thereby. If a bibliographic name or an article name is used as a keyword at the search stage, no hits can be found in the “book” or “book” by the keyword. Therefore,
Prior to registration in the electronic book database 1, pronouns indicating items outside the text, such as "this journal" and "this manuscript", are replaced with the items indicated by the pronouns. When book data is registered in the electronic book database 1, each piece of information is managed in the database by an information object and its identifier (ID), so that the page information becomes meaningless. Therefore, when searching, it is impossible to refer to the reference target according to the search result. Therefore, the reference target is replaced with the link information from the page information. In addition, as link information,
For example, a URL (Uniform Resource Locator) is used.

The conversion of the date information into a predetermined date information display format is performed in order to increase the search hit rate when the date is used as a keyword. For example, if the date information display format is “4 years integer month / two digits integer month / two digits integer day”, then as date information, “
A description such as “May 5, 1997” is “1997/05
/ 05 ". This unifying process is performed by SGM
This is realized by using the tag of the book data that has been converted to L and replacing or changing the data sandwiched between the tags in the SGML conversion file 35.

Finally, the registration processing section 24 executes this SG
The ML file 35 is registered in the database by transmitting it to the electronic book database via the output device 13 (step S28). Note that a DBMS (Data Base Management System) of the electronic book database 1 analyzes the SGML file, decomposes the file into a form suitable for the logical structure of the database, and registers the file. At the time of registration, an identifier (ID) is added as necessary to associate the data, and the data is associated with the ID. FIG. 16 shows a related image of each data constituting the book after registration in the electronic book database 1. The book data registration system 2 operates as described above.

A program for realizing the function of the processing section 21 of the book data registration system 2 shown in FIG. 12 is recorded on a computer-readable recording medium, and the program recorded on this recording medium is stored in a computer system. By reading and executing, the book data may be registered in the electronic book database 1. Here, the “computer system” includes an OS and hardware such as peripheral devices.

As described above, according to the book data registration method and book data registration system of the present invention, the following effects can be obtained. According to the first or sixth aspect of the present invention, the structure of a plurality of types of books is analyzed, items having the same meaning are grouped as similar items to determine the general-purpose structure of the book, and a tag indicating each item is used to determine the general structure. A book structure is defined by defining a general-purpose structure, and book data is registered based on the book structure. In this way, by grouping items having different expressions but having the same meaning, a general-purpose book structure can be defined. By registering the book data to be registered in the database using the book structure definition, it is not necessary to manage the database for each specific field, and the book database can be searched regardless of the field. According to the second or seventh aspect of the present invention, the book structure definition includes a tag for classifying book data that cannot be surrounded by a general-purpose structure of a book. Thereby, even if an item that cannot be surrounded by the general-purpose structure of the book occurs in the book data to be registered, the book data can be classified.

According to the third or eighth aspect of the present invention, the book structure definition includes a tag for holding book-specific information. By providing tags to hold book-specific information such as book numbers,
An electronic book database can be searched based on these unique information. According to the fourth or ninth aspect of the present invention, the book structure definition defines items requiring the same item in a plurality of levels by using a nested structure. By defining in a nested structure in this way, there is no restriction on the number of repetitions, and the item can correspond to any number of steps. According to the invention of claim 5 or claim 10, the standard description linguistic conversion is performed for each article of the book data to be registered. Since a search target is generally a unit of an article, creation of an SGML file for each article facilitates extraction of only the article.

According to the eleventh to thirteenth aspects, a process for unifying predetermined items into a predetermined format is performed. As a result, the search efficiency of the registered book data is improved.
