Description

Content conversion system, content conversion program, and content selection program

The present invention relates to a content conversion technology and a content selection technology, and more particularly to a technology for converting WEB content into content to be displayed on a small-screen device and a technology for selecting a portion to be displayed on a small-screen device from WEB content.

In recent years, terminals (hereinafter referred to as mobile terminals) having a function of accessing the Internet such as mobile phones have become widespread. Such a conventional portable terminal is equipped with a browser that supports only a subset of HTML (Hyper Text Markup Language). For this reason, a WEB content distributor can use a WEB content (hereinafter referred to as a WEB content for a personal computer) written in a normal HTML and a WEB content described for a portable terminal. Content (hereinafter referred to as WEB content for mobile terminals) had to be prepared, which required a lot of budget and labor. In addition, when creating WEB content for mobile terminals based on WEB content for personal computers, there is a problem in that there is a time difference between the two updates.

In recent years, mobile terminals capable of displaying WEB content for personal computers have also appeared. However, since WEB content for personal computers is designed assuming a display with a relatively large resolution, there is a problem in that a mobile terminal having only a display with a lower resolution than a personal computer has a poor operational feeling.

Furthermore, since recent WEB content for personal computers contains a lot of information, there are problems such as an increase in communication charges and communication time when browsing WEB content for personal computers with a mobile terminal.

In order to solve such problems, a technique for converting WEB content for personal computers into WEB content for portable terminals has been proposed. For example, WEB content for non-portable terminals for creating WEB content for portable terminals (corresponding to the above-mentioned WEB contents for personal computers) is displayed on a computer screen for creating WEB contents, and an operator can WEB for portable displays. When the information to be included in the content is instructed, the instructed information is extracted from the WEB content for the non-portable terminal, and the WEB content for the mobile terminal is generated based on the extracted information (see Patent Document 1).

In the technique of this Patent Document 1, an operator or the like creates the WEB content for the portable terminal from the WEB content for the non-mobile terminal by performing the above selection processing on the WEB content for the non-mobile terminal. . Further, in the technique of Patent Document 1, retrieval authority and control of information to be selected are controlled by setting an acquisition authority and a keyword in advance in the information of WEB content for non-mobile terminals.

Also, a mobile terminal for converting the content of a WEB page for a PC on an existing WEB site (equivalent to the above-mentioned WEB content for a personal computer) into a content for a mobile terminal (equivalent to the above-mentioned WEB content for a mobile terminal) A content conversion system for receiving a HTTP request from a mobile terminal to an existing WEB site, receiving predetermined parameter information including the type of the mobile terminal from the mobile terminal, and downloading from the existing WEB site HTML conversion means for converting the information in the HTML language into the XHTML Basic format, document generation means for converting the information converted into the XHTML Basic format into contents for portable terminals using a predetermined conversion rule description file, and the WEB site Or Image conversion means for converting the image format and image size of the downloaded image data for a portable terminal, and page dividing means for dividing the content converted for the portable terminal into a size corresponding to the screen of the portable terminal (See Patent Document 2).

In the technology of this patent document 2, when an HTTP request is received from a mobile terminal, the content of the WEB page for PC is acquired from the existing WEB site, the content is converted into the XHTML Basic format, and further, the content is carried based on a predetermined conversion rule. It is converted to content for the terminal. At this time, according to the specifications of the mobile terminal, the viewability on the mobile terminal is improved by changing the format and size of the image data and dividing the content.

JP 2003-006106 A JP 2003-271508 A

As described above, in the technique of Patent Document 1, since the WEB content for mobile terminals including only the information instructed by the operator can be created on the displayed WEB content for non-mobile terminals, unnecessary information is deleted. Compact content can be created. However, in the technique of Patent Document 1, since an operation for selecting information must be performed for each content, the burden on the operator is large when the number of content is large or when the content is frequently updated. There is a risk that efficient transmission of information may be hindered.

On the other hand, according to the technique of Patent Document 2, the content of the WEB page for the PC of the existing WEB site can be converted into the content for the mobile terminal based on a predetermined conversion rule, so that there is no burden on the operator or the like. However, in the technique of Patent Document 2, since the format is simply changed, there is a high possibility that the converted content includes information that the user of the mobile terminal does not want.

In view of the above problems, an object of the present invention is to provide a content conversion technique for converting a user's desired part from the WEB content into a content and a content selection technique for generating information for selecting the desired part from the WEB content. That is.

In order to solve the above-mentioned problems, a content conversion system according to the present invention is a content conversion system for extracting a specific block from WEB content composed of a plurality of blocks, the block to be extracted A profile recording unit that records a profile including at least one of identification information for identification and position information that defines the position of the block in the WEB content, and access for acquiring a request for access to the WEB content from the terminal A request processing unit, a content acquisition unit for acquiring the WEB content requested to be accessed, and a block at the position corresponding to the block having the identification information or the position information from among the acquired WEB content, Or having the identification information and the location information. Includes searching for blocks in the corresponding position, a block extracting unit which extracts a content generation unit from extracted said block to generate a WEB content that can be displayed on the terminal, to.

Normal web content is described in a markup language such as HTML. In the markup language, blocks surrounded by tags are arranged in parallel or nested. Therefore, based on the structure, the position of a specific block in the WEB content can be defined. Therefore, in this configuration, the profile recorded in the profile recording unit includes at least one of identification information for identifying the block to be extracted and position information for defining the position of the block in the WEB content. ing. Moreover, the name of the tag which comprises a block can be used for the identification information for specifying a block. Some tags can be given identifiers (IDs), names, etc. as attributes. In such tags, not only tag names but also attributes can be used as identification information for more reliable blocks. Can be identified.

When a terminal such as a mobile phone (hereinafter referred to as a mobile terminal) uses the content conversion system of the present invention, the mobile terminal uses this content together with information indicating desired WEB content (hereinafter referred to as acquired content information). Access the conversion system. The access request processing unit receives this access, and acquires the web content based on the acquired content information received together with the access by the content acquisition unit. The block extraction unit has the block having the identification information included in the profile or the block at the position corresponding to the position information included in the profile, or the identification information included in the profile, from the content thus acquired. Then, the block at the position corresponding to the position information included in the profile is searched and extracted. Further, the content generation unit generates WEB content that can be displayed on the terminal from the extracted block.

As described above, in the content conversion system of the present invention, a specific block is extracted from WEB content, that is, WEB content for a personal computer, based on at least one of block identification information and position information, and can be displayed on a mobile terminal. Content, that is, WEB content for mobile terminals is generated. For this reason, if there is a profile, WEB content can be automatically converted, and it is not necessary for an operator or the like to convert WEB content for personal computers to WEB content for portable terminals. If the block structure of the WEB content for the personal computer is the same, even if the content of the WEB content is updated, only the desired block is selected from the updated WEB content and converted to the WEB content for the mobile terminal. be able to. Therefore, in order to convert WEB content, it is possible to efficiently transmit information without imposing a burden on an operator or the like. In addition, if the user or the WEB content provider registers necessary block identification information and position information, mobile WEB content is generated based on the registered block identification information and location information. You can browse WEB content.

When updating the WEB content, there are a case where only the information is changed while the block structure of the WEB content is maintained, and an update accompanied by a change in the block structure. In the latter case, in the above-described content conversion system, there is a difference between the position information of the profile and the position of the desired block in the WEB content, and thus the desired block cannot be extracted.

Therefore, in a preferred embodiment of the content conversion system of the present invention, the block extraction unit should extract the block according to a predetermined search rule when the block to be extracted cannot be searched in the WEB content. Search for and extract blocks.

In this configuration, even when a block cannot be searched based on the profile, the block is searched based on a predetermined search rule. Therefore, even when the block structure of the WEB content is changed, the block is accurately extracted. be able to.

In one preferred embodiment of the content conversion system of the present invention, the content generation unit generates a WEB content based on the processing information transmitted from the terminal or performs a process on a processing server that performs a predetermined process. When the block for transmitting information is extracted by the block extraction unit, the access request processing unit adds access information for accessing the processing server to the WEB content generated from the extracted block. The request relay that transmits the processing information to the processing server specified based on the access information when the access information and the processing information are included in the access request from the terminal acquired by Department.

In this configuration, for example, when a block (form block or the like) for transmitting processing information to the processing server is extracted by the block extraction unit, the content generation unit converts the WEB content generated from the extracted block. Access information for accessing the processing server is added and transmitted to the terminal. On the other hand, when the access request from the terminal includes the access information and the processing information to be transmitted to the processing server, the request relay unit identifies the processing server based on the access information and sends the processing server to the processing server. Processing information is transmitted to the server. Thereby, processing information can be accurately transmitted to the processing server, and desired processing can be executed.

In one preferred embodiment of the content conversion system of the present invention, when the information to be extracted is specified on the WEB content displayed on the terminal, the identification information and the location information are related to the WEB content. Is generated based on the block to which the information specified in the file belongs.

In this configuration, a user, an operator, etc. (hereinafter referred to as a user, etc.) indicate information to be extracted while the WEB content for a PC to be converted is displayed on a terminal (preferably having a larger display than a portable terminal). Then, the block to which the indicated information belongs is specified based on the relationship between the indicated position and the displayed WEB content, and the identification information and the position information are determined based on the block structure of the WEB content, the position of the block, and the like. Generated. Thereby, identification information and position information can be created by a simple method. Moreover, since the WEB content for portable terminals is generated based on such identification information and position information, the WEB content for portable terminals including only the information desired by the user or provided by the WEB content provider is generated. be able to.

The technical features of the content conversion system of the present invention can also be applied to similar content selection programs. As such a content conversion program, there is provided a content conversion program for causing a computer to function as a content conversion system for extracting a specific block from WEB content composed of a plurality of blocks. In order to identify the block to be extracted included in the profile recorded in the profile recorded in the profile recording unit, the function of obtaining the request for accessing the WEB content, the function of obtaining the WEB content requested to be accessed The block having the identification information or the position corresponding to the position information from the acquired WEB content based on at least one of the identification information of the block and the position information defining the position of the block in the WEB content Block, if Has a function of searching for and extracting a block having the identification information and corresponding to the position information, and a function of generating WEB content that can be displayed on the terminal from the extracted block. ing. Of course, the above-described additional features of the content conversion system can also be applied to such a content conversion program.

In order to solve the above-mentioned problem, the content selection program of the present invention is a content selection device that generates a profile for selecting only a specific block from WEB content composed of a plurality of blocks. A content selection program to be functioned, the function of acquiring a user's designated position on the WEB content obtained via a network and displayed on the display of the terminal, the displayed WEB content, and the designated position And a function for identifying the information at the indicated position, a function for identifying the block to which the identified information belongs in the WEB content, identification information for identifying the identified block, and the block The position that represents the position in the WEB content And a, a function of generating the profile comprising at least one of the information.

In this configuration, the content selection program of the present invention can be configured as an add-on that functions on a browser, for example. In this case, WEB content to be converted is displayed on the browser, and the user or the like instructs information (text, image, etc.) extracted from the displayed WEB content. In response to this instruction, it identifies which block in the WEB content indicates the instructed information, and generates a profile including the identification information and position information. Thereby, a profile can be easily generated. Further, by using the profile generated in this way in the above-described content conversion system, it is possible to generate WEB content for mobile terminals that includes only information desired by the user or provided by the WEB content provider.

The present invention has an effect that a WEB content for a portable terminal including only desired information can be easily created from a WEB content for a personal computer.

Hereinafter, embodiments of a content conversion system and a content selection program according to the present invention will be described with reference to the drawings.

〔overall structure〕
FIG. 1 is a system configuration diagram using the content conversion system in the embodiment. In this embodiment, the content conversion system A of the present invention is connected to a wide area network N such as the Internet. The wide area network N is connected to a plurality of WEB servers W for publishing WEB contents. A terminal such as a mobile phone using the content conversion system A (a terminal in the present invention, hereinafter referred to as a mobile terminal T) is connected to a wide area network N via a public mobile phone network and a base station C. ing. Note that in this description, when simply referred to as WEB content, it represents WEB content for a personal computer.

〔Outline of processing〕
FIG. 2 is a conceptual diagram of a system using the content conversion system in the embodiment. First, an http request is transmitted from the portable terminal T to the content conversion system A (# 01). The http request includes information for accessing the content conversion system A and information for specifying the URL (Uniform Resource Locator) of the web content to be acquired, as will be described later. The content conversion system A that has received this http request specifies the URL of the WEB content based on the http request by a method described later (# 02), and transmits the http request based on the URL (# 03). In response to the http request from the content conversion system A, the WEB server W holding the WEB content indicated by the URL returns an http response, that is, a WEB content (HTML file or the like) (# 04). In the example of FIG. 2, the WEB content sent from the WEB server W is composed of blocks (1) to (6). The content conversion system A that has acquired the WEB content extracts a necessary block from the acquired WEB content based on a pre-recorded profile (# 05). Furthermore, the content conversion system A processes the extracted block into a format that can be displayed on the mobile terminal T (# 06), and transmits it to the mobile terminal T as an http response (# 07). In the example of FIG. 2, blocks (2), (4), and (6) are extracted by the content conversion system A.

[Description of each function unit]
FIG. 3 is a functional block diagram of the content conversion system A of the present invention. The content conversion system A according to the present embodiment is configured by a general-purpose computer, and is acquired by a profile recording unit 11 that records a profile, an access request processing unit 12 that acquires an HTTP request from the mobile terminal T, and an access request processing unit 12. A specific block from the WEB content acquired by the content acquisition unit 13 based on the profile stored in the content acquisition unit 13 that acquires the WEB content from the corresponding WEB server W based on the HTTP request and the profile storage unit And a content generation unit 15 for generating WEB content that can be displayed on the mobile terminal T from the blocks extracted by the block extraction unit 14 (hereinafter referred to as WEB content for mobile terminals). To have.

In this embodiment, the content conversion system A is configured by a general-purpose computer, and the profile recording unit 11 is configured by a nonvolatile recording medium such as a hard disk. The access request processing unit 12, the content acquisition unit 13, the block extraction unit 14, and the content generation unit 15 are configured by software with a central processing unit (CPU) as a core. However, hardware or software and hardware are included. It does not matter even if it is the structure which cooperates.

The profile recording unit 11 records a profile including at least one of position information and identification information for defining a block to be extracted from WEB content (one page). FIG. 4 is an example of a profile in the embodiment. In this embodiment, the profile is described in XML (eXtensible Markup Language), but may be described in another format.

As shown in FIG. 4, the profile includes at least one page block. The page block corresponds to each WEB content, and the page tag has url and src as essential attributes. The attribute value of url is a part used when the mobile terminal T accesses the content conversion system A, and the attribute value of src is the URL of the WEB content that the mobile terminal T originally wants to access. A method for using the page tag will be described later.

Each page block includes at least one block block. This block block holds information for specifying a block to be extracted from the WEB content. The block tag in the form of this embodiment has two types of attributes: an attribute that defines the position of the block to be extracted (position information in the present invention) and an attribute that defines the block to be extracted (identification information of the present invention). have. In the present embodiment, the former is an index, and the latter is attr_text, inner_text, id, name, href, src, class, style, alignment, tag.

The description method of the attribute value of attribute index is described below.

WEB contents are generally described in a markup language such as HTML or XHTML. In the markup language, a block is formed by enclosing information such as a sentence with tags, the block is arranged in parallel and hierarchically (nested), and information is described by a tree structure. Therefore, each block in the WEB content can be specified by the position in the tree structure.

For example, in the WEB content represented by the HTML file shown in FIG. 5, the position information that defines the block including the information “press release” can be shown as follows. It is assumed that the depth of the block hierarchy is represented by an integer with the highest hierarchy being 1, and the order of the blocks is represented by an integer with the first block being 0. In the example of FIG. 5, the block of the p tag including the information “press release” is the second block in the block of the div tag in the higher hierarchy. Therefore, the block of the p tag is described as “1:” with respect to the block of the div tag. “:” Is a delimiter. Next, looking at the position of the block of the div tag, since it is the first block in the block of the td tag, the block of the div tag is described as “0:” with respect to the block of the td tag. When these are combined, the position of the block of the p tag with respect to the block of the td tag is described as “0: 1:”. When this description rule is applied to the highest block, the p tag block is described as “5: 1: 0: 0: 1” in the HTML file of FIG. That is, the block of the p tag is described as the second block in the first block in the first block in the second block in the fifth block in the HTML file of FIG. The position information determined in this way becomes the attribute value of the attribute index.

Note that the description method of the attribute value of the attribute index is not limited to the above-described method. For example, it is possible to use a combination of a block name and a position in the block, such as “div: table: tr: td + 2”. This example represents the second td block in the tr block in the table block in the div block. Of course, as a method for describing the attribute value of the attribute “index”, other methods may be used as long as the object of the present invention is achieved.

The attributes other than the index of the block tag are for directly specifying the block to be extracted by matching with the name of the tag defining the block and the attribute value of the tag. For example, if the attribute value of the attribute tag is “table”, the block defined by the table tag is the block to be extracted. If the attribute value of the attribute class is “release”, a block defined by a tag whose tag attribute is “release” is a block to be extracted.

In this way, it is possible to specify a block with only one of position information and identification information. However, if the block structure is changed when the WEB content is updated, a correct block cannot be extracted. Therefore, it is desirable to use both attributes. In this case, the block to which the information “press release” in the example of FIG.
<block class = "release" tag = "p" index = "5: 1: 0: 0: 1:">
It can be expressed as.

The access request processing unit 12 has a function of acquiring access from the portable terminal T, rewriting the URL (Uniform Resource Locator) used for the access, and transmitting the URL to the content acquisition unit 13.

In this embodiment, since the access request processing unit 12 substantially functions as a WEB server, the mobile terminal T accesses the content conversion system A using http (HyperText Transfer Protocol). At this time, the mobile terminal T needs to indicate the URL of the WEB content to be actually accessed. It is possible to embed the URL of the WEB content to be actually accessed into the URL when accessing the content conversion system A from the portable terminal T using the form parameter or the like. However, in the present embodiment, the page described above is used. Correspondence by tag attribute value is used.

That is, when the URL transmitted from the portable terminal T includes a character string that matches the attribute value of the attribute url of the page tag, the attribute value of the attribute src of the page tag is the WEB content actually acquired. It is assumed that it is a URL. However, since the access request unit 12 according to the present embodiment cannot access the profile, only the URL is rewritten and the rewritten URL is transmitted to the content acquisition unit 13.

Specifically, the access request processing unit 12 deletes the protocol and its own server name from the URL when accessed from the mobile terminal T. For example, if the server name of the content conversion system A is “www.abc.com” and the mobile terminal T accesses “http://www.abc.com/news/”, the access request processing The unit 12 deletes the protocol (“http”) and its server name (“www.abc.com”) from this URL to obtain “/ news /”. This character string is transmitted to the content acquisition unit 13.

The content acquisition unit 13 has a function of acquiring the rewritten URL from the access request processing unit 12, specifying the WEB content to be acquired based on the rewritten URL and the profile, and acquiring the WEB content. .

Specifically, the content acquisition unit 13 searches the profile for a page tag having an attribute value of the attribute url that matches the rewritten URL (“/ news /” in the above example) acquired from the access request processing unit 12. Then, the attribute value of the attribute src of the retrieved page tag is set as the URL of the WEB content to be acquired. When using the profile of FIG.
<page url = "/ news /" src = "http://www.news.com/index.html">
Is searched. Therefore, the attribute value “http://www.news.com/index.html” of the attribute src of the page tag is the URL of the WEB content to be acquired.

The content acquisition unit 13 transmits an http request using the URL specified in this way, and acquires WEB content (HTML file). The acquired HTML file is transmitted to the block extraction unit 14 together with the rewritten URL acquired from the access request processing unit 12.

The block extraction unit 14 searches and extracts blocks from the WEB content acquired by the content acquisition unit 13 based on the profile. Since the rewritten URL is transmitted to the block extraction unit 14 together with the HTML file, the block extraction unit 14 extracts a page block in which the attribute value of the url attribute of the page block matches the URL, and A block is extracted from the WEB content based on the block block in the page block.

In the above example, since the rewritten URL of the WEB content is “/ news /”, the block extraction unit 14 searches the profile for a page block having this URL as the attribute value of the attribute url. In the example of FIG.
<page url = "/ news /" src = "http://www.news.com/index.html">
<block class = "release" tag = "p" index = "5: 1: 0: 0: 1:">
<choice src = "class = 'news'" tag = "p"/>
</ block>
</ page>
Is searched.

The block extraction unit 14 extracts a block corresponding to the block block included in the page block searched in this way. FIG. 6 is a flowchart showing the flow of block extraction processing.

First, the block extraction unit 14 selects one from the block blocks included in the page block searched as described above. In the above example, first <block class = "release" tag = "p" index = "5: 1: 0: 0: 1:">
<choice src = "class = 'news'" tag = "p"/>
</ block>
Is selected.

The block extraction unit 14 extracts the attribute value of the attribute index (“5: 1: 0: 0: 1:” in the above example) as the position information from the block block selected in this way, and uses it as the position information. A matching block is searched from the WEB content (HTML file), and the tag of the block is set to D (# 11). In this description, the process of substituting the block search result into a variable is performed. However, when the corresponding block is not searched, null is substituted into the variable.

When D is not null, that is, when a block matching the position information is searched (Yes branch of # 12), it is determined whether or not an attribute indicating identification information is set in the current block tag (# 13). At this time, if the attribute indicating the identification information is not set (No branch of # 13), D becomes the search result and the block defined by D is extracted (# 17). On the other hand, when an attribute indicating identification information is set in the block tag (Yes branch of # 13), it is determined whether or not the attribute value of D matches the identification information set in the block tag. (# 14). At this time, if they match (Yes branch of # 14), D becomes a search result, and a block defined by D is extracted (# 17). If the WEB content from which the block is extracted is the HTML file of FIG.
<p class = "release">
Press release </ p>
Are extracted.

On the other hand, if the attribute value of D and the identification information set in the block tag do not match (No branch of # 14), the tag Q having the identification information closest to the position of D is searched (# 15). . In the embodiment, priority is given to identification information, and the similarity of attribute values is higher as identification information with higher priority matches. For example, it is assumed that D has “release” and “p” set as attribute values of the attribute class and tag, and there are a tag whose attribute value is “release” and a p tag as search targets. In this state, if the priority of the attribute class is higher than the attribute tag, it is determined that the tag whose attribute value is “release” is more similar to the tag D.

When Q is searched in this way (Q is not null) (No branch at # 16), Q becomes the search result and a block defined by Q is extracted (# 17). On the other hand, if Q is not searched, it is determined whether or not a choice tag exists in the current block block (# 21). As described above, since the choice tag exists in the current block block (Yes branch of # 21), the process proceeds to # 22.

The choice tag in the form of this embodiment defines exception processing when a block is searched based on the attribute value of the block tag. That is, when a block cannot be searched based on the attribute value of the block tag, the tag is searched using the attribute value of the choice tag. For this purpose, the choice tag according to the present embodiment has attributes src and tag. The attribute value (second identification information) of the attribute src is in the format of attribute name = attribute value of the block tag above the choice tag. Further, the attribute value (second identification information) of the attribute tag is the same as the attribute value of the attribute tag of the block tag above this choice tag. The choice tag of the current block block is <choice src = "class = 'news'" tag = "p"/>
Therefore, when the search by the upper block tag fails, the block of the p tag whose attribute value is “news” is searched and set to X (# 23). When X is searched in this way (X is not null) (No branch of # 24), X becomes the search result, and a block defined by X is extracted (# 17).

If the choice block does not exist (No branch of # 21) or the second identification information is not set in the choice tag (No branch of # 22), the search fails and this block block is supported. The extraction process of the block to be completed is completed.

On the other hand, if D is not searched in the process of # 01 (D is null) (No branch of # 12), the tag P that exists first is searched backward from the attribute value of the attribute index (# 18). The tag S having the identification information closest to the position of P is searched (# 19). At this time, if S is null (No branch of # 20), the process proceeds to # 11 described above. On the other hand, when S is not null (Yes branch of # 20), S becomes a search result, and a block defined by S is extracted (# 17).

The block extraction unit 14 performs the above-described processing on all the block blocks included in the retrieved page block, and transmits the extracted block to the content generation unit 15.

The content generation unit 15 that has acquired the block extracted from the block extraction unit 14 has a function of converting the acquired block into a WEB content format for mobile terminals. The information acquired from the block extraction unit 14 is a part of the WEB content and is incomplete as a format. Therefore, even if the block information is transmitted to the mobile terminal T as it is, it cannot be displayed on the mobile terminal T. Therefore, the content generation unit 15 adds a tag or the like essential as a WEB content (HTML file) to the block, and shapes the block into a format that can be displayed on the mobile terminal T. At this time, if information about the specifications of the mobile terminal T is obtained, the size of the image included in the WEB content is converted to a size suitable for the display of the mobile terminal T, or the mobile terminal T It may be converted to a compatible HTML version.

The WEB content for mobile terminals generated in this way is transmitted to the access request processing unit 12 and transmitted to the mobile terminal T as an http response.

[Process flow]
FIG. 7 is a flowchart showing the flow of processing in the embodiment. First, an access request is transmitted from the portable terminal T to the content conversion system A (# 31). For example, an http request for the URL “http://www.abc.com/news/” is transmitted. This http request is acquired by the access request processing unit 12.

The access request processing unit 12 that has acquired the http request deletes the protocol and its own server name from the URL, and rewrites the URL (# 32). The protocol is http and the server name is www. abc. com, the access request processing unit 12 deletes these characters from the URL and rewrites the URL to “/ news /”. The rewritten URL is transmitted to the content acquisition unit 13.

The content acquisition unit 13 that has acquired the rewritten URL collates the rewritten URL with the profile recorded in the profile recording unit 11, and specifies the URL of the WEB content (# 33). When the URL of the WEB content can be specified, the content acquisition unit 13 transmits an http request using the URL, and acquires the WEB content as an http response to the request (# 34). The acquired WEB content is transmitted to the block extraction unit 14 together with the rewritten URL.

On the other hand, the block extraction unit 14 first collates the rewritten URL with the profile recorded in the profile recording unit 11, and acquires the position information and identification information of the block to be extracted (# 35). Thereafter, based on the acquired position information and identification information, a corresponding block is extracted from the acquired WEB content (# 36). The blocks extracted in this way are transmitted to the content generation unit 15.

The content generation unit 15 that has acquired the block from the block extraction unit 14 shapes the acquired block into a format that can be displayed on the mobile terminal T, for example, by adding a tag, and generates WEB content for the mobile terminal (# 37). The generated WEB content for mobile terminals is transmitted to the access request processing unit 12.

The access request processing unit 12 that acquired the WEB content for the mobile terminal returns the acquired WEB content for the mobile terminal as an http response to the http request from the mobile terminal T. Thereby, the mobile terminal T can receive and display WEB content for mobile terminals including only necessary blocks.

Thus, in the form of the present embodiment, the block to be extracted is specified based on the position information and identification information included in the profile, so that even if the content of the WEB content is updated, the block The block can be appropriately extracted without updating the information for extracting. In addition, when the structure of the WEB content is slightly changed due to the update of the content of the WEB content, flexible block detection can be performed by performing a block search process using the position information and the identification information. it can.

In the content conversion system in the form of the first embodiment, only the block is extracted from the WEB content and the format is shaped. For this reason, it is not possible to handle WEB content that transmits information from the portable terminal T and causes the processing server to perform processing. Therefore, in this embodiment, a content conversion system A that can handle such WEB content will be described. In addition, the same code | symbol is attached | subjected to the function part similar to the form of Example 1, and detailed description is abbreviate | omitted.

FIG. 8 is a configuration diagram of a system using the content conversion system A in the embodiment. In this embodiment, a processing server S is connected in addition to the system of the first embodiment. The processing server S has a function of dynamically generating WEB content (whole or part) or executing predetermined processing based on information acquired from the mobile terminal T (hereinafter referred to as processing information). I have. For example, authentication or search.

FIG. 9 is a functional block diagram of the content conversion system in the embodiment. The form of the present embodiment is different from the form of the first embodiment in that the access request processing unit 12 and the operation of the content generation unit 15 and the request relay unit 16 are provided.

When the content generation unit 15 in the form of the present embodiment includes a block for transmitting processing information to the processing server S in the WEB content acquired from the WEB server W by the content acquisition unit 13, for example, a form block, Information (hereinafter referred to as access information) for accessing the processing server S is added to the WEB content.

In addition, when the access request from the mobile terminal T includes access information and processing information, the access request processing unit 12 transmits the information to the request relay unit 16.

The request relay unit 16 transmits the processing information to the processing server S specified based on the access information acquired from the access request processing unit 12, causes the processing server S to execute a predetermined process, and the WEB as the processing result. Get content.

10 and 11 are flowcharts showing the flow of the processing of the content generation unit 15 of the content conversion system A and the processing at the time of obtaining an access request in the embodiment.

First, the processing flow of the content generation unit 15 will be described. First, when there is an access request for WEB content from the mobile terminal T, a block is extracted by the processes of # 31 to # 36 in FIG. 7, and the process proceeds to the content generation unit 15. Similar to the above-described embodiment, the content generation unit 15 adds a tag to the extracted block as appropriate, and formats the extracted block into a format as WEB content for mobile terminals that can be displayed on the mobile terminal T (# 41). At this time, the content generation unit 15 determines whether or not the extracted block includes a block for transmitting processing information to the processing server S (# 42). For example, when the block extraction unit 14 extracts a block including a form block (Yes branch of # 42), access information for accessing the processing server S is added to the mobile terminal WEB content generated in # 41. (# 43).

The access information in the embodiment includes at least a URL for causing the processing server S to execute a process (in the case of a form tag, an attribute value of an attribute action), and a URL for accessing the content conversion system A. It is. Furthermore, when session management is required between the portable terminal T and the content conversion system A, the content generation unit 15 can generate a session ID and include it in the access information.

The addition of the access information can be realized, for example, by embedding an input tag in which the attribute value of the attribute type is “hidden” and the attribute value of the attribute value is the above value in the WEB content for portable terminals. For example, <input type = "hidden" name = "MpsBase" value = "/ mps / retrieve /"/>
<input type = "hidden" name = "ServerURL" value = "http://www.abc.com/retrieve"/>
Add tags such as. In addition, when processing information is transmitted from the mobile terminal T, the attribute value of the attribute action of the form tag of the WEB content for mobile terminals is rewritten so that the transmission destination of the http request is the content conversion system A, or It is necessary to embed a script that operates equivalent to such a form tag in the WEB content for portable terminals. As a result, when the user inputs information (processing information) requested by the form in the portable terminal T and submits it, the processing information and the access information are transmitted to the content conversion system A. For example, when a user inputs a search expression for searching for information and submits it, the search expression is transmitted to the content conversion system A together with the access information as processing information.

On the other hand, if the block extracted by the block extraction unit 14 does not include a form block or the like, the processing of the content generation unit 15 ends, and the process proceeds to # 38 in FIG.

Next, the flow of processing when receiving an access request from the mobile terminal T will be described. The process of FIG. 11 corresponds to the process of # 31 of FIG. First, when receiving an access request from the portable terminal T (# 51), the access request processing unit 12 determines whether or not the access request includes processing information and access information (# 52). For example, when the method of the http request from the portable terminal T is “post”, or when the method is “get” and the URL (Uniform Resource Identifier) includes the URL of the processing server S, the processing information is included. It is determined that

If the access request includes processing information or the like (Yes branch at # 52), the access request processing unit 12 extracts the processing information and the access information from the access request (# 53), and the request information is transferred to the request relay unit 16 To communicate.

The request relay unit 16 that has acquired the processing information and the access information from the access request processing unit 12 specifies the processing server S based on the access information, and transmits an http request to the specified processing server S (# 54). As described above, since the URL of the processing server S is included in the access information, the processing server S to which the processing information should be transmitted can be specified. The processing information is transmitted as a request parameter of an http request.

The processing server S performs a predetermined process (for example, a search based on a search expression) for this http request, an http response is returned, received by the request relay unit 16, and a web content portion of the http request is extracted ( # 55). When a session ID is transmitted from the processing server S, the request relay unit 16 performs session management by storing the session ID and the session ID transmitted to the mobile terminal T in association with each other.

Thereafter, the process shifts to # 35 in FIG. 7 (# 56), and the process such as block extraction is performed in the same manner as in the embodiment described above.

On the other hand, when processing information or the like is not included in the access request from the portable terminal T (No branch of # 52), the process is shifted to # 32 of FIG. 7 (# 57), and the above-described embodiment mode The same processing is performed.

As described above, in the embodiment, when the extracted block includes a block for transmitting processing information to the processing server S such as a form block, a content generation unit is generated for the generated WEB content. When the access information or the like is added to the content conversion system A and the access request including the processing information is acquired, the request relay unit 16 transmits the processing request to the processing server S. Then, based on the response to the processing request, WEB content for mobile terminals is generated and transmitted to the mobile terminal T. For this reason, content conversion can also be performed on dynamically generated WEB content and the like. In the above description, the block for transmitting processing information to the processing server S has been described as a form block. However, the block is not limited to this, and may be a block for transmitting processing information to the processing server S. For example, other blocks such as JavaScript (registered trademark) may be used.

The content selection program of the present invention will be described below with reference to the drawings. The content selection program of the present invention is for generating a profile (particularly position information and identification information) used in the above-described content conversion system. In this embodiment, the content selection program is configured as an add-on that operates on a browser installed on a terminal P such as a personal computer having a display with a higher resolution than the portable terminal T. The program may have a browser function.

FIG. 12 shows an example of the operation screen of the content selection program. WEB content (HTML file) is displayed on the display of the terminal P by the function of the browser B. As shown in the figure, the window Bw of the browser B is divided into a content display area Rc for displaying WEB content (HTML file) and a preview area Rp for displaying information in the WEB content selected by the user. Yes. In the state shown in the figure, the WEB content displayed in the content display area Rc includes a block having a company logo as information (hereinafter referred to as logo block BL1) and a block having information as a navigation button group (hereinafter referred to as navigation block BL2). A block having new product information as information (hereinafter referred to as a new product information block BL3), a block having new arrival information as information (hereinafter referred to as a new arrival information block BL4), and a block having recruitment information as information ( Hereinafter, it is broadly divided into employment information block BL5). In FIG. 12, portions corresponding to the respective blocks are surrounded by dotted lines. When information desired to be displayed on the mobile terminal T is selected for the WEB content displayed on the browser B in this way, the selected item is displayed in the preview area Rp. In this example, the logo block BL1 and the navigation block BL2 are selected by the user's selection operation. Therefore, in the preview area Rp, a selection block SB1 corresponding to the logo block BL1 and a selection block SB2 corresponding to the navigation block BL2 are displayed.

FIG. 13 is a diagram showing an operation when it is desired to further select the employment information block BL5 in the state of FIG. When there is a block to be selected, the user operates a pointing device (hereinafter referred to as a mouse) connected to the terminal P to display the block to be selected (in this example, the employment information block BL5). Menu M is displayed on the area, and [Mobile Page Service] → [Add to Mobile Page] is selected.

In response to this operation, the content selection program of the present invention operates, and as shown in FIG. 14, a selection block SB3 that displays information included in the selected employment information block BL5 in the preview area Rp is generated. .

As described above, when the content selection program of the present invention is used, only a desired block can be selected by simply selecting the WEB content displayed on the browser B with the mouse.

FIG. 15 is a functional block of the content selection program in the embodiment. As shown in the figure, the content selection program in the embodiment is acquired by the indicated position information acquisition unit 21 and the indicated position information acquisition unit 21 that acquire the position information instructed by the user using a pointing device such as a mouse. WEB content (HTML file) used for specifying the information (text, image, etc.) existing at the indicated position based on the position information and the display state in the content display area Rc of the browser B ) An instruction block specifying unit 22 for specifying a block to which the information specified in FIG. 2 belongs, and a profile generating unit for generating a profile including at least one of position information and identification information of the block specified by the instruction block specifying unit 22 23. WEB computer currently displaying the generated profile A preview generation unit 24 that generates a preview applied to the browser and displays it on the preview area Rp of the browser B, a profile editing unit 25 that edits a profile based on a user operation, and the generated profile as a profile of the content conversion system A A profile transmission unit 26 that transmits to the content conversion system A for recording in the recording unit 11 is provided. Note that the content selection program of this embodiment operates on the CPU of the terminal P, and each functional unit can access the memory 27 of the terminal P used as a working memory.

The designated position information acquisition unit 21 has a function of acquiring the position information designated by the user with the mouse. As described above, when the user selects a block, the user moves the mouse pointer to the display position of the block to be selected and opens the menu. Therefore, the designated position information acquisition unit 21 acquires the position information of the mouse pointer when the menu is opened from the OS (or window manager). The acquired position information is transmitted to the instruction block specifying unit 22.

The instruction block specifying unit 22 has a function of specifying a block specified by the user. The blocks designated as the blocks to be selected by the user on the browser are the WEB content (HTML file), the display state (font size, scroll state, etc.) of the content display area Rc of the browser B, and the designated position information acquisition unit 21. It can be determined based on the position information acquired by. Therefore, the instruction block identification unit 22 requests the browser B for the current display state and HTML file, and identifies the block selected by the user based on the position information acquired from the instruction position information acquisition unit 21. Information on the identified block is transmitted to the profile generation unit 23. In addition, the information for specifying a block here can use the format of the block position information in the embodiment described above.

The profile generation unit 23 generates a profile including information (at least one of position information and identification information) that can specify the block specified by the instruction block specifying unit 22. Further, when editing is performed by the profile editing unit 24, the profile includes information corresponding to the edited content. Further, the profile generation unit 23 holds various parameters for generating a profile. This parameter can be set by the user through a dialog.

The preview generation unit 24 generates a preview when displayed on the mobile terminal T based on the generated profile. Specifically, the preview generation unit 24 extracts a block by applying the profile generated by the profile generation unit 23 to the WEB content displayed in the content display area Rc of the browser B, and is necessary for that. A tag or the like is added, it is formatted in the HTML format, and is displayed in the preview area Rp of the browser B.

The profile editing unit 25 has a function of editing the profile generated by the profile generation unit 23. The profile editing unit 25 according to the present embodiment allows the user to edit the profile when the interaction using the GUI described above cannot sufficiently extract only the block intended by the user. Multiple profile editing functions are provided so that they can be extracted.

The first editing function of the profile editing unit 25 is a function that enables editing of the preview displayed in the preview area Rp. Examples of preview editing include changing the size of an image, converting an image into a character string, and adding / deleting a block (information). In the example of FIG. 12, the logo block BL1 includes a logo image, but the corresponding selection block SB1 is text. Such conversion can be realized by using the attribute value of the attribute “alt” of the img tag of the WEB content or by allowing the user to input an alternative character. In the example of FIG. 12, the home item is deleted from the selection block SB2 corresponding to the navigation block BL2.

FIG. 16 is an example of a profile generated in the state of FIG. The preview area Rp in FIG. 14 includes three selection blocks SB1, SB2, and SB3. Therefore, the profile of FIG. 16 also includes three block blocks. As described above, the selection block SB1 is a block corresponding to the logo block BL1, and converts an image into text. This selection block SB1 is in the profile
<block id = "logo" tag = "img" index = "...">
<block_optset>
<tag_conv change_img2txt = "1">
</ block_optset>
It is expressed as Note that a block_optset block is included in the block block, but this block is for describing processing options for the selected block. In this example, a tag_conv tag is included in the block_optset block, and an option is specified by the attribute of this tag. In this example, the attribute value of the attribute change_img2txt is set to “1”. This gives an instruction to convert the image into text, whereby the logo image is replaced with text, and a display like the selection block SB1 in FIG. 14 is generated.

In the profile, the selected block SB2 is
<block id = "navi" index = "...">
<src_delete id = ”home” />
</ block>
It is expressed. As described above, the selection block SB2 corresponds to the navigation block BL2, and “Home” is deleted. This deletion of “home” is expressed by an src_delete tag. The src_delete tag can have an attribute for specifying a block. In this example, the block is specified by the attribute value of the attribute id. By this specification, the corresponding block in the block indicated by the block block to which the src_delete tag belongs can be deleted. In this example, the information corresponding to “home” is deleted by deleting the block whose attribute value of the attribute id is “home”.

Similarly, the selection block SB3 is in the profile,
<block id = "recruit" index = "..."/>
It is expressed.

Although the description of index is omitted in the profile of FIG. 16, the attribute value of the attribute index is the position information of the block in the WEB content as in the above-described embodiment, and can be described according to the rules described above. .

In addition, the profile editing unit 25 has other editing functions such as a function that allows the user to directly edit the profile using an editor or the like, and a function that allows the user to change settings such as a profile generation rule.

When the profile is changed via the profile editing unit 25, a preview is generated by the preview generation unit 24, and the display of the preview area Rp of the browser B is updated.

The profile transmission unit 26 has a function of transmitting the profile generated by the profile generation unit 23 to the content conversion system A and recording it in the profile recording unit 11 of the content conversion system A. Therefore, the profile transmission unit 26 acquires the profile from the profile generation unit 23, accesses the content conversion system A using the OS communication function of the terminal P, and transmits the profile after the authentication is completed.

FIG. 17 is a flowchart showing the flow of processing in the embodiment. The flow of processing in this embodiment will be described with reference to this figure. First, the user operates browser B to display WEB content (HTML file) for which a profile is to be generated (# 61). When the user designates information to be displayed on the mobile terminal T, that is, a block, by the above-described method for the displayed WEB content (# 62), the designated position information acquisition unit 21, the designated block specifying unit 22, and the profile generation unit 23, the function of the preview generation unit 24 generates or updates the profile (# 63), and updates the preview of the preview area Rp (# 64). Similarly, when the user edits the preview by the method described above, the profile is updated (# 63), and the preview is updated (# 64). When the user sees this preview and wants to customize it further, the user can edit the profile by operating the mouse etc., and display the dialog for changing the settings and the editor for editing the profile. Can be activated (Yes branch of # 65). Based on the user operation acquired through the dialog or the editor, the profile is edited by the function of the profile editing unit 25 (# 68), and the preview of the preview area Rp is updated by the function of the preview generation unit 24 (# 64). .

When these processes are repeated and the block selection is completed (Yes branch of # 66), the profile is transmitted to the content conversion system A by the profile transmission unit 26 (# 67).

As described above, when the content selection program of the present invention is used, a block to be extracted can be specified in a state where the WEB content is displayed on the browser B, so that a profile can be easily created. This content selection program is desirably open to both general users (users who browse web content from the mobile terminal T) and web content providers. If a general user creates a profile using this content selection program, records the profile in the above-described content conversion system A, and browses the WEB content for mobile terminals via the content conversion system, the information he / she wants to browse WEB content for mobile terminals including only the mobile phone can be obtained. In addition, if a profile created by a web content provider is registered in the content conversion system A and the URL of the content conversion system A is notified to a general user, the WEB for mobile terminals is separate from the WEB content for personal computers. WEB content for mobile terminals can be provided to general users without creating content.
