The page 41 is a group of data displayed at one time by a browsing means such as a Web browser.
Each page has one or more containers 42 and links.

The container 42 is a part for storing one or a plurality of resources 43 or the container 42.

The resource 43 is data that constitutes meaningful information for humans. Here, the resource 43 is
Character (text), the smallest unit of an HTML document
It refers to data or image (image) data, and in each case, one resource is not a whole sentence or an image but a minimum unit modified by an HTML tag.

The style 45 is data related to the page 41, the container 42, and the resource 43 that make up the content, and is format information such as font type, layout, and attributes. Here, all the information that modifies the resource 43 such as character data or image data is the style 45.

The link 44 is data indicating the connection between the objects, and is a link from the resource 43 to the container 42 or the page 41.

FIG. 4 shows a configuration example of the data extraction / structure conversion processing section 2.

The data extraction / structure conversion processing unit 2 includes a normalization processing unit 201, a separation processing unit 202, a category specifying unit 203, a module generation processing unit 204, a relationship setting unit 205, and a customization processing unit 206. ,
Reconstruction processing means 207 is provided.

The normalization processing means 201 acquires an HTML document, which is the Web content 4, as an input source from the Web server 11 that is the storage source, and acquires the acquired HTML.
This is a means for converting the description of the document into the XHTML format for normalization and temporarily storing the converted XHTML data.

The separation processing means 202 is a normalization processing means 2
It is a means for separating the resource 43 and the style 45 from the XHTML data generated in 01 and specifying the link information in the XHTML document.

The category specifying means 203 is a business category database (business category DB) based on the word data extracted from the top page of the XHTML document.
210 is a means for identifying the business category of the XHTML document (content) with reference to 210. The business category DB 210 is a database that manages company names, product names, etc. for each business category.

The module generation processing means 204 is an XHT.
It is a means for grouping elements decomposed into the minimum unit of ML data for each function to generate a module, determining the role of each element in the module, and giving a meaning to the module.

The relationship setting means 205 is means for giving a module relationship indicating a master-slave relationship between modules and the like.

The customization processing unit 206 is a unit that corrects the inter-module relationship provided by the relationship setting processing unit 205 or changes the content of the resource 43, for example, according to an instruction input of the user of the present system.

The reconfiguration processing means 207 reconfigures the tree structure between pages using the link information of the XHTML document, and arranges the resource 43, which is the minimum unit, for output based on the module relationship and the tree structure. XM
It is a means for reconstructing L data. Reconstructed XML
The data is stored in the content DB 5.

FIG. 5 is a diagram for explaining the processing of the data extraction / structure conversion processing section 2.

The normalization processing means 201 is the Web server 1
Web acquired from the administrator of 1, the content creator, etc.
URI (Uniform Resource Identifier) of content 4
Based on s), all the HTML pages linked in the same domain are acquired from the Web server 11. Here, all the HTML pages mean a set of pages that can be referenced by relative paths arranged in the same processing device. Links to other sites are not considered because they are outside the scope of the same content.

Then, as shown in FIG. 5A, the normalization processing means 201 examines the tags of each page of the HTML document and converts them into an easily processable XHTML format according to the XML description method. In a general HTML document, there are ambiguity problems related to end tags, such as the end tag not being closed, and a variety of descriptions such as the description of attributes being different. Therefore, in the HTML document as it is, This is because there are some disadvantages in the subsequent processing.

Here, the HTML document is simply XM.
Since it only needs to be handled as L data, it is the most HT
The HTML document acquired according to the XML specification as XML close to the ML description is converted into data in XHTML format, but the conversion processing into XHTML format converts the data according to the strict XHTML specification. Instead, complete the ambiguity of the description by completing the missing tags and deleting unnecessary tags.
Convert for the purpose of shaping into a description format that facilitates the subsequent processing. Specifically, it refers to the following conversion processing.・ Example of closing empty elements such as <img>, <br>, <hr>, etc.) <br> → <br /> ・ If the tags of the same inline element are nested, they are regarded as unnecessary tags and one of them is deleted. Example of deleting a pair) <b><a name= "aiueo"><b> AIUEO </ b></a></b> → <b><a name= "aiueo"> AIUEO </a></b> ・ Nest the crossing of the start tag and end tag correctly according to the following rules Rule 1: If the block element and the inline element cross, put the inline element in the block element Rule 2: When block elements or inline elements cross each other, the order is adjusted to the tag that appears first. Example) <ul><li><b><aname="aiueo"> Aiueo </ b></a></ul></li> → <ul><li><b><aname="aiueo"> aiueo </a></b></li></ul> ・ <p Compensation for missing end tags such as>, <li> according to the following rules Rule 3: Closed immediately before the same tag appears or when the end tag of the parent tag of the tag is encountered Not complete tags -Complement the place where the attribute value is omitted with the attribute name) <td align = "left" valign = "top"nowrap> → <td align = "left" valign = "top" nowrap = "nowrap"> Example of allocating individual tags that decorate multiple minimum elements such as text and image) <a href="index.html"><img src = "pressrelease.gif" alt = "Press Release" width = "87" heigh t = "12"/><img src = "delta-b.gif" alt = "" width = "10" height = "13"/></a> → <a href="index.html"><img src = "pressrelease.gif" alt = "Press release" width = "87" heigh t = "12"/></a><ahref="index.html"><img src = "delta-b.gif "alt =""width=" 10 "height =" 13 "/></a>("-"is a symbol indicating a half-width underline.) Next, as shown in FIG. , Separation processing means 202
Divides the resource 43 into a separate file for each minimum unit from the XHTML data, and further separates the style 45 attached to the resource 43 as a separate file. Also,
The separation processing unit 202 determines the container 42 containing the resource 43 and separates the style 45 attached to the container 42. Further, the link 44 which is the structural information in the page 41 is specified.

In general, it is difficult to extract a semantically cohesive portion from an HTML document.
The reason is that, in addition to character data and images directly related to human beings, the HTML document has scattered format information (style) for modifying them and tags for describing the page structure.

The separation processing means 202 extracts the resource 43 from the XHTML document and separates the style 45 that modifies the resource 43 by the following method. Here, the rule for specifying the resource 43 and the style 45 is defined as follows. -It is a text node surrounded by tags. -One resource includes all tags of inline level elements that surround text nodes (tags that directly modify characters or images, excluding block level elements such as table <table> and list <ul>). However, the anchor <a> is not included among the inline elements. -When a line break tag <br> appears, the resource immediately before the line break tag is included as one resource. -All tags and attributes except the line break tag <br> are stored as style information.・ One horizontal line <hr> is one resource.

An example of a part of the HTML document and examples of the resource 43 and the style 45 separated from the example are shown below. Example) Part of HTML document <a href="http://www.f.com/"><img src = "img.gif" width = "415" height = "64" alt = "F" border = "0"/></a><b><i> Product Information </ i></b><br/><ahref="products/gis/pd.html"> Location Information Display System </a>> Example) Created resource resource r1: <resource id = "1" type = "image" src = "img.gif" br = "false" link = "http: // ww wfcom /"> F </ resource> -Resource r2: <resource id = "2" type = "text" src = "" br = "true" link = ""> Product information </ resour ce> -Resource r3: <resource id = "3" type = "text" src = "" br = "false" link = "products / gis / pd.h tml"> Location information display system </ resource> Example) Styles created s1: <style id = " 1 "><width> 415 </ width><height> 64 </ height><border> 0 </ border></style> -Style s2: <style id =" 2 "><b/><i / ></style> Further, the category specifying means 203 cuts out the data portion of the XHTML data excluding the definition word of the top page and extracts the word in. To generate a box, to identify the industries category words such as company name and product name in the word index and search the industry category DB210 as a keyword. As the industry category, for example, the Japanese standard industry classification is used.
If the industry category cannot be determined as a result of the search, a synonym list of words extracted based on a synonym database (not shown) is generated, and the industry category DB 210 is searched using the generated synonym list. And specify the industry category.

Next, as shown in FIG. 5C, the module generation processing means 204 replaces the resource 43, which is an element disassembled into the minimum unit in the XHTML document, with
Based on the tags, groups are created for each predetermined function such as table, list, sentence paragraph, etc., and a module is created. Then, the role of each element in the module is determined and given as a meaning.

That is, TABLE, UL, OL, D
L, P, HR, TR, TH, TD, LI, TD, TH
Based on the tags such as, up to which element is collected as a table or a list is regarded as one module, and what is meant by the module is interpreted from the constituent elements.

For example, when a table is composed of several elements, the role of the element is determined such that the element is an item corresponding to the heading of the table or a value for the heading, and the content of the module is determined. And the semantic information such as “table of XX” and “list of ΔΔ” is added as metadata. As another example, when a module including only link items appears on a page, the semantic information “index” is added to the module.

In addition, referring to the style 45, the resource 4
Character data corresponding to the title of the table or list may be extracted from the format information such as the character size and the centering of the text of No. 3 and used as the semantic information.

Then, as shown in FIG. 5D, the relationship setting means 205 gives a master-slave relationship between the modules in the page in module units. For example, in a module in the same hierarchy, when a table module comes next to a text module and the semantic information is the same or similar, the context information (relation) that the text module is related to the next table module is set. To add.

Then, as shown in FIG. 5 (E), the customization processing means 206 corrects the module relation added by the relation setting means 205 according to the input instruction of the user. Further, the customization processing unit 206 collects only the headline items by using the tag and newly creates an index within the page, or substitutes the summary sentence as a new resource 43 when the text of the resource 43 is a long sentence. The user makes dynamic changes by inputting an arbitrary instruction, such as changing each item of tabular data to data expressing in list form.

Next, the reconstruction processing means 207 is executed by the processing shown in FIG.
As shown in (F), the tree structure between pages is reconstructed based on the link 44 of the XHTML document, and the resources 43 are arranged in order according to this tree structure and the module relationship to generate an XML document which is intermediate data. .

Here, when the tree structure between pages is reconstructed, the reconstructing processing unit 207 weights a module that is frequently linked or a keyword that appears in the top page and is the same as or similar to the keyword. It is also possible to increase the priority of the modules having the semantic information, and configure the page including these modules to be in the upper hierarchy. For example, if the top page contains keywords such as “press release”, “new arrival information”, and “update information”, a page that consists of modules to which the same semantic information as those keywords is added,
Configure the page so that it is linked directly from the top page.

In this case, by weighting the keywords, the modules having the meaning information of “press release” and “new arrival information” are configured so as to be directly linked from the top page, and the meaning of “update information” is defined. Information-bearing modules can also be organized into pages with lower links.

Further, the reconfiguration processing means 207 has the industry category configuration information 211 defining page configuration information for each predetermined industry category, and rebuilds the tree structure according to the page configuration information selected in the identified industry category. You can also do it.

The reconstruction processing means 207 may also generate age-specific versions of XML data whose contents are changed according to the age of the accessor when generating the XML data.

FIG. 6 shows a processing flowchart of the data extraction / structure conversion processing section.

In the data extraction / structure conversion processing unit 2, the normalization processing unit 201 acquires all HTML pages in the same site as the Web contents 4 (step S
1), conversion to XHTML format (step S2).
Then, the separation processing unit 202 separates the resource 43 and the style 45 (step S3), and further extracts link information (step S4). Then, the category specifying unit 203 specifies the business category of the site (step S5), and the module generation processing unit 204 groups the resources 43 to generate a module (step S6), and the meaning of the module from the role of each element. Is specified and added (step S7). Then, the relationship setting means 205 associates the modules (step S8), and the customization processing means 206 customizes them (step S9). Then, the reconfiguration processing unit 207 reconstructs the tree structure of the site based on the link information (step S10), arranges the resources 43 in order according to the reconstructed tree structure and module relationships, and creates the content in the XML data format. Reconfigure (step S11).

Next, the content generation processing section 3 will be described. FIG. 7 shows a configuration example of the content generation processing unit 3.
The content generation processing unit 3 includes a specification information acquisition processing unit 301, a template selection unit 302, a dynamic generation processing unit 303, and a template database (template DB) 310.

The specification information acquisition processing means 301 is means for acquiring specification information such as the model name of the mobile terminal 13 and the carrier name to be used when an access request is issued from the mobile terminal 13. As the specification information, information such as the area and time when the access request is made and the age of the accessor may be added at the data center 14 which relays the access request.

The template selecting means 302 is means for selecting a corresponding template from the template DB 310, which is the information defining the content display format stored in advance, based on the acquired spec information.

In the templates stored in the template DB 310, the language that can be interpreted by the Web browser of the mobile terminal 13 is classified according to the model of the mobile terminal 13 for each carrier,
Information such as display screen size, data capacity, and types of colors that can be supported is defined. Also, the template may include a style sheet defining page format information.

The dynamic generation processing means 303 is means for generating the corresponding XML data stored in the content DB 5 in the mobile content 6 according to the template selected from the template DB 310. For example, when the language defined in the template is C-HTML, each page of XML data is divided so as to correspond to the display screen size, links between pages are reconstructed, and C-H
It is rewritten in TML to generate the mobile content 6. When the template includes a style sheet, the dynamic generation processing unit 303 generates the mobile content 6 according to the format information of the style sheet.

When the specification information includes access information such as access area and accessor age, the dynamic generation processing means 303 extracts the corresponding XML data from the content DB using these access information as keys. The mobile content 6 can also be generated.

FIG. 8 shows a processing flowchart of the content generation processing section 3.

When an access request is received from the portable terminal 13 (step S21), the specification information acquisition processing means 3
The specification information added by the data center 14 is acquired by 01 (step S22). Then, the template selecting means 302 selects a corresponding template from the template DB 310 based on the specification information (step S23). Then, the dynamic generation processing means 303
By this, the content (XML data) required for the access request is extracted from the content DB 5 (step S2
4) Generate the mobile content 6 from the XML data according to the template (step S25), and respond the generated mobile content 6 to the requesting mobile terminal 13 (step S26). Each data example when the mobile content 6 corresponding to a small screen size such as a mobile phone terminal is reconfigured from the Web content 4 of the normal site is shown.

FIG. 9 shows a display example of Web contents suitable for browsing on a normal computer terminal or the like. Figure 10
