In addition, the text C5 has a strikethrough defined in a part of the text by a <STRIKE> tag. The text C3, C4, and C5 are defined by the <body> tag as a whole display mode. As described above, the page source is data (hereinafter also referred to as “description data”) in which the regulation information is described in order, and is data that indicates the regulation information.
When the acquisition unit 201 acquires the regulation information indicated by the page source (description data) and the content indicated by the page source, the page source and the acquired content include content other than text as the acquisition result. For example, the content data (image data or the like) is supplied to the extraction unit 202. If the obtaining unit 201 obtains the web page regulation information and content shown in FIG. 7, the obtaining unit 201 obtains the page source shown in FIG. 8 and supplies the obtained page source to the extracting unit 202. Hereinafter, in the present embodiment, a case where a web page includes only text content will be described.

  The extraction unit 202 is an extraction unit that extracts the content described below from the content acquired by the acquisition unit 201. The content extracted by the extraction unit 202 is content displayed in a display mode defined by the regulation information that satisfies the first condition. The first condition is a condition set in advance as a condition used when the extraction unit 202 performs extraction. When the specified information acquired by the acquiring unit 201 satisfies the first condition, the extracting unit 202 extracts the content displayed in the display mode specified by the specified information from the content acquired by the acquiring unit 201. Extract. In the present embodiment, the first condition is a condition that is satisfied when the regulation information is regulation information predetermined in the bookmark service providing system 1. The extraction unit 202 is a function realized by the control device 21 and the storage device 22 in cooperation. A method by which the extraction unit 202 performs the above extraction will be described below.

  The storage device 22 stores the regulation information that satisfies the first condition described above, that is, the regulation information determined in advance. This regulation information regulates the display mode of the content to be extracted, and is hereinafter referred to as “extraction regulation information”. In the bookmark service providing system 1, three pieces of extraction regulation information are defined. The first extraction regulation information is regulation information determined in advance as that which defines the display mode of information (this is referred to as “page information”) conveyed by the web page in the form of articles, posts, explanations, and the like. Yes, for example, regulation information such as <article> tag and <meta> tag. Also, depending on the web page, there may be no <article> tag, so the <body> tag is determined as the first defining information that defines the page information of such a web page. The second extraction regulation information is regulation information predetermined as indicating a paragraph existing in the page information portion indicated by the first extraction regulation information. For example, regulation information such as <p> tag and <div> It is. In addition to such definition information, the description of the <meta> tag is often the second extraction, which often defines page information searched by the search engine (mainly descriptive text explaining the contents of the web page). It is decided as regulation information. The third extraction regulation information is regulation information used when content is not extracted by the first and second extraction regulation information, and is, for example, a <title> tag.

  First, the control device 21 is supplied with the above-described page source and content data (only the page source in this embodiment) as the regulation information and content acquired by the acquisition unit 201. The control device 21 extracts a portion (hereinafter, referred to as “specified portion”) in which the display mode is defined by the first extraction defining information from the supplied page source. In the example of FIG. 8, the control device 21 extracts the specified portion P <b> 1 sandwiched between <body> tags. The prescribed portion P1 includes contents called texts C3, C4, and C5 and prescribed information such as <font> tag, <br> tag, <a> tag, and <STRIKE> tag. Further, the control device 21 extracts a <meta> tag <meta name...

  Next, the control device 21 extracts a specified portion in which a display mode is specified by the second extraction specifying information from the content and the specifying information extracted based on the first extraction specifying information. In the example of FIG. 8, the control device 21 extracts a specified portion P2 sandwiched between <div> tags and a defined portion P3 sandwiched between <p> tags from the defined portion P1. The prescribed portion P2 includes text C4, <font> tag, <br> tag, and <a> tag. The prescribed portion P3 includes text C5 and a <STRIKE> tag. Also, the control device 21 extracts the content (text C2 in the example of FIG. 8) defined as the description by using the <meta> tag including the description. In this case, the <meta> tag including the description is the second extraction regulation information.

When the regulation information is included in the regulation part extracted as described above, the control device 21 deletes the regulation information. In the example of FIG. 8, the control device 21 deletes the <font> tag, the <br> tag, and the <a> tag included in the specified portion P2, and deletes the <STRIKE> tag included in the specified portion P3. Note that the control device 21 does not delete the <meta> tag description because no definition information is included in the description of the <meta> tag. The defined part P2 from which the defined information has been deleted in this way represents the text C4, and the defined part P3 represents the text C5.
In addition, when the content is not left as a result of extraction by the first and second extraction regulation information, the control device 21 defines the display mode by the <title> tag that is the third extraction regulation information. The existing text C1 is extracted from the page source.

  As described above, the extraction unit 202 displays the content extracted based on the first, second, and third extraction specification information in a display mode specified by predetermined specification information (extraction specification information). Extracted from the content acquired by the acquisition unit 201 as the content to be displayed. The extracting unit 202 supplies the extracted content (texts C2, C4, and C5 in the example of FIG. 8) to the specifying unit 203.

  The specifying unit 203 is a specifying unit that specifies content satisfying the second condition among the contents extracted by the extracting unit 202. The second condition is defined in the bookmark service providing system 1 as a condition for determining whether or not the content of the web page is more detailed than other content. In the present embodiment, a condition that the largest index indicating the amount of text among the text extracted as content is satisfied as the second condition. The index indicating the amount of text here is, for example, the ratio of the number of characters of each text to the total number of characters of the extracted text (hereinafter referred to as “text ratio”). The specifying unit 203 is a function realized by the control device 21. The control device 21 performs this specification by the following method.

  The control device 21 calculates the amount of each text (for example, the number of characters) for all the text extracted as content. In the example of FIG. 8, the control device 21 calculates 5, 126, and 39 characters as the text amounts of the texts C2, C4, and C5. And the control apparatus 21 specifies the content with the largest amount of the calculated texts. Note that the control device 21 may calculate the ratio of the number of characters of each text (that is, the text ratio) to the calculated total of the texts, and specify the content having the largest calculated text ratio. Further, the control device 21 may specify using the file size of each text instead of the text ratio. These (text amount, text ratio, and text file size) are all indexes representing the amount of text, and the control device 21 may specify based on these indexes. In this way, when the extracted content includes text, the specifying unit 203 selects the text with the largest index indicating the amount of text from among the content that satisfies the second condition. As specified. In the example of FIG. 8, the specifying unit 203 calculates 0.03, 0.74, and 0.23 as the text ratios of the texts C2, C4, and C5, respectively. It is specified as content satisfying the condition 2. The identification unit 203 supplies the identified content to the generation unit 204.

The generation unit 204 is a generation unit that generates partial information indicating a part of the content according to the content specified by the specifying unit 203. The generation unit 204 is a function realized by the control device 21 and performs this generation by the following method, for example. When the identified content is text, the control device 21 generates information represented by text having a predetermined number of characters (for example, 100 characters) from the beginning as partial information.
The control device 21 stores the data indicating the partial information generated by the generating unit 204, the access destination of the web page that is the basis of the partial information, and the title of the web page as shown in FIG. Is generated as bookmark data and stored in the storage device 22.

[Operation]
The bookmark service providing system 1 performs the service providing process described above based on the above configuration.
FIG. 9 is a sequence diagram showing the operation of each device in the service providing process. The service providing process is started when a user having the information processing apparatus 20 starts up the browser 30 and performs an operation of accessing a web page. When this operation is performed, the information processing apparatus 20 transmits the above-described page request data for requesting a web page to the access destination of the web page (step S11). In this example, the information processing apparatus 20 transmits page request data to the web server apparatus 40. When receiving the page request data, the web server device 40 transmits the web page data of the requested web page to the information processing device 20 (step S12).

  The information processing apparatus 20 acquires the regulation information and at least one content from the web page data received in Step S12 (Step S13). Steps S11 and S13 are operations performed by the acquisition unit 201 illustrated in FIG. The information processing apparatus 20 displays the web page indicated by the acquired web page data (step S14). For example, the information processing apparatus 20 acquires the regulation information and content shown in FIG. 8 and displays the web page shown in FIG. In this state, when the user performs an operation (bookmark creation operation) for selecting “bookmark creation” in the menu B2 shown in FIG. 7 in order to create a bookmark, the information processing apparatus 20 accepts the bookmark creation operation. (Step S15), a generation process for generating bookmark data indicating a bookmark as shown in FIG. 2 is started.

  First, the information processing apparatus 20 extracts content displayed in the display mode defined by the above-described extraction regulation information (predetermined regulation information) from the acquired content (step S16). Step S <b> 16 is an operation performed by the extraction unit 202. Next, the information processing apparatus 20 specifies content that satisfies the second condition described above among the extracted content (step S17). Step S17 is an operation performed by the specifying unit 203. Subsequently, the information processing apparatus 20 generates the above-described partial information according to the specified content (step S18). Step S18 is an operation performed by the generation unit 204. The information processing apparatus 20 generates bookmark data indicating the generated partial information, the title of the displayed web page, and the access destination (step S19). The information processing apparatus 20 stores the generated bookmark data (step S20) and transmits the bookmark data to the bookmark server apparatus 10 (step S21). The bookmark server device 10 holds the bookmark data transmitted in step S21 (step S22).

  By performing the service providing process described above, the bookmark server device 10 holds the bookmark data generated by each information processing device 20. The bookmark server device 10 similarly holds bookmark data generated by other information processing devices 20 that execute the browser 30. When a bookmark list is requested from these information processing apparatuses 20, the bookmark server apparatus 10 generates a list of bookmarks that are held, and transmits list data indicating the generated list to the information processing apparatus. . By displaying the list indicated by the list data received by the information processing apparatus, the user can supply bookmarks created by other users.

  As described above, the information processing apparatus 20 extracts content whose display mode is defined by the first and second extraction defining information. The regulation information not included in these includes, for example, tags related to tables (<TABLE> tags, <TD> tags, <TH> tags, etc.), tags related to forms such as buttons and check boxes (<FORM > Tag, <INPUT> tag, <LABEL>, etc.). Since the table displays a plurality of pieces of information side by side, the table is often used to define a display mode of words of about one word to several words. Forms provide functions such as entering text and selecting one of several options, so as with tables, words (for example, “name:” or “blood type”) : "Etc.) is often used to define the display mode.

  On the other hand, the first and second extraction regulation information stipulates information (<div> tag and <p> tag) often included in the text included in the main body of the web page, and page information such as articles and letters. (<Article> tag). The content whose display mode is defined by these defining information is often a sentence having a plurality of sentences, and the contents of the web page are often expressed in more detail than other contents. In addition, the description of the <meta> tag is for defining the description of the web page, and therefore the content of the web page is often expressed in more detail than other content. In this way, the information processing apparatus 20 can extract content that often represents the details of the web page in more detail than other content.

  In addition, the information processing apparatus 20 specifies the extracted text that satisfies the second condition (in this embodiment, the text that has the largest amount). A sentence with a large amount of text is easier to represent a detailed content than a sentence with a small amount of text. The information processing apparatus 20 can generate partial information that expresses the details of the web page in more detail by specifying text with a large amount of text compared to when specifying content regardless of the amount of text. As a result, according to the present embodiment, it is possible to extract from the web page a part that makes it possible to grasp the details in more detail than when specifying the content regardless of the amount of text.

[Second Embodiment]
Hereinafter, the second embodiment of the present invention will be described focusing on differences from the first embodiment. In the first embodiment, text is specified as content. In the second embodiment, a case where an image is specified will be described.
The extraction unit 202 of this embodiment extracts an image by the method described in the first embodiment even when the content acquired by the acquisition unit 201 includes image content. In this case, the <img> tag is determined in advance as the second extraction regulation information, and the extraction unit 202 extracts the second extraction regulation from the regulation part extracted based on the first extraction regulation information from the page source. The <img> tag that is information is extracted. The extraction unit 202 extracts the image indicated by the image data by extracting the image data in which the extracted <img> tag defines the display mode from the content data supplied from the acquisition unit 201. The extraction unit 202 supplies the image data of the extracted image to the specifying unit 203.

  The identifying unit 203 identifies an image that satisfies the second condition from the images extracted by the extracting unit 202. In the present embodiment, a condition that an extracted image having the largest image size (total file size or number of pixels) is satisfied as the second condition. The specifying unit 203 is a function realized by the control device 21. The control device 21 performs this extraction, for example, by the following method.

  The control device 21 refers to the header of the image data supplied from the extraction unit 202 and acquires the size (file size or number of pixels) of each image. And the control apparatus 21 specifies the image data with the largest size of the acquired image as an image which satisfy | fills 2nd conditions. When there are a plurality of image data having the largest image size, the control device 21 determines that the <img> tag that defines the display mode of the image indicated by the image data first appears in the <body> tag, The image satisfying the second condition is specified. In this way, when the content acquired by the acquisition unit 201 includes image content, the specifying unit 203 satisfies the determination information for the image having the largest image size among the images. Identify as content. The above identification is performed. The specifying unit 203 supplies image data indicating the specified image to the generating unit 204.

  The generation unit 204 generates partial information according to the image specified by the specifying unit 203. For example, the generation unit 204 generates partial information obtained by processing the image indicated by the image data supplied from the specifying unit 203 into an image having a predetermined number of pixels (for example, 128 vertical × 128 horizontal). The information processing apparatus 20 uses the partial information generated by the generation unit 204 to generate bookmark data in step S19 shown in FIG.

  The image extraction by the extraction unit 202 and the image specification by the specifying unit 203 described in the present embodiment are performed when an image is included in the content. Further, the extraction of text by the extraction unit 202 and the specification of text by the specification unit 203 described in the first embodiment are performed when text is included in the content. That is, when both text and images are included in the content, the respective extraction and identification are performed, and when only one is included, the extraction and identification of the included content is performed. Done.

  FIG. 10 is a diagram illustrating an example of a bookmark in the present embodiment. FIG. 10 shows a bookmark A2 generated when both text and image are extracted and specified. The bookmark A2 includes the title A11 and the access destination A12 illustrated in FIG. 2, and the text A23 and the image A24 (128 × 128 pixels) included in the partial information generated by the generation unit 204. . According to the present embodiment, as shown in FIG. 11, a bookmark representing an image included in the web page is generated. Therefore, the user can read the bookmark from the web page as compared with the case where the bookmark does not include an image. A part that makes it possible to grasp the contents in more detail can be extracted.

[Third Embodiment]
Hereinafter, the third embodiment of the present invention will be described focusing on differences from the first and second embodiments. In the first and second embodiments, the regulation information and at least one or more contents are acquired from a web server device (for example, the web server device 40 shown in FIG. 1) that provides a web page to any information processing device 20. In the third embodiment, a case will be described in which prescribed information and at least one content are acquired from a web server device that does not provide a web page unless the user is authenticated as a registered user.

  FIG. 11 is a diagram showing an overall configuration of the bookmark service providing system 1a according to the present embodiment. The bookmark service providing system 1a includes a web server device 40a for members instead of the web server device 40 shown in FIG. Further, the information processing apparatus 20 stores a program for the dedicated browser 30a. In the bookmark service providing system 1a, the above-described authentication by the bookmark server device 10 can be performed only from the information processing device 20 in which the program of the dedicated browser 30a is executed. In other words, the dedicated browser 30a is a browser having a dedicated function necessary for using the service provided by the bookmark server device 10. The web server device 40a for members holds identification information (for example, user ID) for identifying a user and a password associated with the identification information as member information for authenticating a registered member. It has a function to authenticate the user with the member information. The member web server device 40a returns the member web page data indicating the member web page to the page request data from the authenticated information processing device 20, but this authentication is not performed. In response to the page request data from the information processing apparatus 20, the web page data for members is not returned. In this way, the web server device for members 40a provides a service for providing a web page for members only to registered members. Such member web server devices include, for example, members that register only medical personnel as members and provide a member web page on which information on pharmaceuticals is posted. This makes it possible to provide only the medical staff with information on medicines that are only allowed to be provided to medical staff.

  FIG. 12 is a sequence diagram showing the operation of each device in the service providing process of this embodiment. This service providing process is started when the user who possesses the information processing apparatus 20 performs an operation for starting the dedicated browser 30a shown in FIG. When this operation is performed, the information processing apparatus 20 executes the program of the dedicated browser 30a stored in the storage device 22 and activates the dedicated browser 30a (step S30). When the dedicated browser 30a is activated, a screen for inputting authentication information (user identification information and password) is displayed on the display device 24 of the information processing device 20. When the user performs an operation for inputting authentication information, the information processing apparatus 20 receives an input of the authentication information (step S31), and transmits authentication information data indicating the received authentication information to the bookmark server apparatus 10 ( Step S32). Upon receiving the authentication information data, the bookmark server device 10 authenticates the registered user (registered user) based on the authentication information indicated by the data (referred to as “reception authentication information”) (step S33). When the stored authentication information (referred to as “stored authentication information”) matches the received authentication information, the bookmark server device 10 authenticates the user identified by the identification information included in the received authentication information as a registered user. Then, notification data for notifying that authentication has been performed is transmitted to the information processing apparatus 20 (step S34).

After receiving the notification data, the information processing device 20 displays a member web page for accessing member web sites provided by the member web server device 40a by user operation and inputting member information, for example. When the user performs an operation to input member information, the information processing apparatus 20 transmits member information data indicating the member information to the member-oriented web server apparatus 40a (step S35). The web server device for members 40a authenticates the user as a registered member based on the received member information (step S36), and transmits web page data for members to the information processing device 20 (step S37). After the information processing device 20 displays the transmitted web page data for members, the page request data and the web page data for members are transferred between the information processing device 20 and the web server device 40a for members by user operation. Are exchanged (step S38). Here, when the user performs a bookmark creation operation (operation for selecting “bookmark creation” in menu B2 shown in FIG. 7), the information processing apparatus 20 accepts the bookmark creation operation (step S39) and accepts this operation. The bookmark data of the web page for the member displayed at the time of generation is generated (step S40). Then, the information processing apparatus 20 stores the generated bookmark data (step S41) and transmits it to the bookmark server apparatus 10 (step S42). The bookmark server device 10 holds the received bookmark data (step S43).
Note that the order of the authentication by the bookmark server device 10 from steps S31 to S34 and the authentication by the member web server device 40a from steps S35 to S37 may be reversed. For example, when the user who browses the web page for members wants to create a bookmark, the bookmark server device 10 is authenticated.

  The information processing apparatus 20 can acquire web page data for members from the web server apparatus for members 40a by being operated by a user registered as a member and performing the above authentication. As a result, the acquisition unit 201 illustrated in FIG. 6 acquires the provision information and content of the web page for members that is provided by the web server device 40a for members and requires authentication. On the other hand, the bookmark server device 10 exchanges data with the information processing device 20, but does not exchange data with the web server device for members 40a. For this reason, a web page for members is not provided from the web server device for members 40a to the bookmark server device 10, and the bookmark server device 10 can generate a bookmark including partial information of the web pages for members. Can not.

  In the present modification, bookmark data representing a part of the web page for members generated in the information processing apparatus 20 is held in the bookmark server apparatus 10 by performing the operation of each step shown in FIG. Thus, according to the present embodiment, the bookmark server device 10 that cannot acquire the web page data for members can hold the bookmark data representing a part of the web page data for members. Also, in the information processing apparatus 20, after storing the bookmark data, even if the authentication by the member web server apparatus 40a and the authentication by the bookmark server apparatus 10 are not performed, from the partial information included in the stored bookmark data, The content of the web page for members can be grasped by the user.

[Modification]
Each embodiment mentioned above is only an example of implementation of the present invention, and may be changed as follows. Moreover, you may implement combining each embodiment mentioned above and each modification shown below as needed.

(Modification 1)
In each embodiment described above, the extraction unit 202 extracts a specified part based on the first extraction specification information from the page source, and further extracts a specified part based on the second extraction specification information from the extracted specification part. However, it is not limited to this. For example, the extraction unit 202 may extract a specified portion based on the first extraction specification information and the second extraction specification information whose combination is determined in advance from the page source. The first extraction rule information and the second extraction rule information whose combinations are determined in advance are, for example, the <p> tag in the <article> tag and the <div> tag in the <body> tag. In the former case, the extraction unit 202 does not extract all of the defined portions sandwiched between <article> tags, but extracts only the defined portions sandwiched between <p> tags, and in the latter case, < Rather than extracting all the defined parts sandwiched by the body> tag, only the defined parts sandwiched by the <div> tags are extracted.

In addition, in the page source of a web page, content whose display mode is defined by the <div> tag is included in the <div> tag (so-called nesting), or the <div> tag includes < In some cases, content whose display mode is defined by the p> tag is included.
FIG. 13 is a diagram illustrating an example of a page source. In FIG. 13, a <body> tag D1 includes a <div> tag D2, and a <div> tag D2 includes <div> tags D31 and D32. The <div> tag D31 includes <p> tags D41 and D42. <P> Tags D41 and D42 define the display mode of the text “XXXXXX” and “◇◇◇◇◇”, respectively. The <div> tag D32 defines the display mode of the text “◎◎◎◎◎”. In the case shown in FIG. 13, the extraction unit 202 extracts the specified portion sandwiched between the lowest second specified information (that does not include other second specified information). In the example of FIG. 13, the extraction unit 202 extracts the specified portions sandwiched between the <p> tags D41 and D42 and the <div> tag D32. In this case, since the other specified information is not included in the extracted specified part, the extraction unit 202 extracts the extracted specified part as content as it is.

(Modification 2)
In each of the above-described embodiments, the extraction unit 202 extracts all the specified parts sandwiched by the first extraction regulation information from the page source, and is sandwiched by the second extraction regulation information among the extracted regulation parts. All of the prescribed parts are also extracted, but not limited to this. The extraction unit 202 may extract content based on the priority order determined for the extraction regulation information in the bookmark service providing system 1. The extraction unit 202 of this modification is a function realized by the control device 21 and the storage device 22 in cooperation as in the above-described embodiments. The storage device 22 stores a table in which the extraction regulation information and the priority order are associated with each other.

  FIG. 14 is a table showing an example of a table in which the extraction rule information and the priority order are associated with each other. In this table, three “priorities” from “1” to “3” have three “<article> tag”, “<p> tag” in “<body>” tag, and “other tag” “Extraction rule information” is associated. These “priorities” indicate that the smaller the number, the higher the priority (that is, “1” has the highest priority). With reference to this table, the control device 21 first extracts the specified portion sandwiched between the <article> tags if the <article> tag is included in the specified information acquired by the acquiring unit 201. If the <article> tag is not included, the control device 21 determines that the specified portion sandwiched between the <p> tags is included in the specified information if the <p> tag in the <body> tag is included. Extract. When the <p> tag in the <body> tag is not included, the control device 21 specifies based on other extraction specifying information (description of <meta> tag, <div> tag, <p> tag, etc.) Extract the part.

  The first condition in this modification is that when the acquisition unit 201 acquires a plurality of extraction rule information (specifically, the first and second extraction rule information), the acquired certain extraction rule information is It is satisfied when the priority order determined as described above is higher than the other extracted regulation information. In other words, the first condition is a condition that is satisfied by the extracted extraction regulation information having the highest priority. In this case, the extraction unit 202 displays the extracted extraction rule information having the highest priority as the extraction rule information satisfying the first condition in the display mode defined by the extraction rule information. Content to be extracted. In this modified example, the priority order is determined in the order of the extraction specification information that is likely to specify the display mode of the content that expresses the details of the web page in more detail than other content. Compared with the case where the ranking is not determined, the content representing the details of the web page in more detail is extracted, and as a result, the generated partial information represents the details of the web page in more detail. Therefore, according to the present modification, it is possible to extract a part from the web page that makes it possible to grasp the details in more detail than when the priority order is not set.

  In the table shown in FIG. 14, three priorities are defined. However, the present invention is not limited to this, and two priorities may be defined, or four or more priorities may be defined. . Moreover, the priority order may be defined for all of the first, second, and third extraction regulation information. In this case, different types of extraction regulation information are not extracted at the same time. In either case, it is desirable that the priority order be determined based on the high possibility described above. Further, the extraction unit 202 may extract a specified portion based on the extraction specification information included in a predetermined order from the highest priority. In this case, the extraction unit 202 defines the extracted extraction rule information included in a predetermined order from the above-described high priority as extraction rule information satisfying the first condition, based on the extraction rule information. The content displayed in the display mode is extracted. In FIG. 14, one piece of extraction rule information is associated with one priority, but a plurality of pieces of extraction rule information may be associated. In this case, the extraction unit 202 extracts the content included in the extracted specified portion if any one of the items associated with one priority order can be extracted based on the extracted specified information. By doing so, it is possible to extract the content displayed in a manner prescribed by the extraction regulation information having the highest priority.

(Modification 3)
In each embodiment described above, the extraction unit 202 deletes the regulation information when the regulation information is included in the regulation part extracted from the page source. However, the extraction unit 202 may extract the regulation information together with the content without deleting the regulation information. That is, the extraction unit 202 extracts content together with the definition information that defines the display mode of the content and the definition information other than the extraction definition information. In this case, the generation unit 204 generates, as partial information, a page source that includes the regulation information extracted together with the content and represents the extracted content, and the information processing apparatus 20 includes a bookmark (bookmark including the partial information) Data).
FIG. 16 is a diagram illustrating an example of a bookmark generated in the present modification. In FIG. 16, the bookmark A4 displayed on the browser is shown. In addition to A11 and A12 shown in FIG. 2, the bookmark A4 includes a text A41 that is the content of the web page. The text A41 is decorated with font enlargement and line feed, similar to the text B42 shown in FIG. Thus, according to this modification, a part of the web page included in the bookmark can be displayed in the same display manner as the web page.

(Modification 4)
In each of the above-described embodiments, the extraction unit 202 deletes the regulation information when the regulation information is included in the regulation part extracted based on the extraction regulation information. May be deleted. For example, the extraction unit 202 deletes the <a> tag, the <font> tag, the <strong> tag, the <table> tag, and the like as the definition information for decorating characters. Further, the extraction unit 202 deletes a tag including a predetermined character string in <> as definition information that defines content such as an advertisement that is not directly related to the content of the web page, and further, the display mode is determined by the tag. Delete the specified content. According to this modification, it is possible to delete only the regulation information that is not desired to be included in the partial information.

(Modification 5)
The specifying unit 203 may use a second condition different from each of the above-described embodiments. For example, the specifying unit 203 may specify the content based on the position where the content is described in the page source (description data described above). In this case, for example, the specifying unit 203 specifies, as the content satisfying the second condition, the extracted content whose position described in the page source is closest to the top of the page source. In the example shown in FIG. 8, when content is extracted by the extraction unit 202 as in the first embodiment, texts C2, C4, and C5 are extracted. In this case, the specifying unit 203 specifies the text C2 described at the position closest to the top of the page source as the text that satisfies the second condition. In the example of FIG. 8, the case where the content is text is shown, but the specifying unit 203 similarly specifies the content even when the content is an image or a moving image. In this case, the specifying unit 203 specifies the content whose description of the location where the content data is stored is closest to the top of the page source as the content that satisfies the second condition.

  In this modification, as described above, the content whose position described in the page source is closest to the top of the page source is specified. In the first and second extraction regulation information described above, the description of the <meta> tag described in the <head> tag is the <p> tag or the <div> tag described in the <body> tag, or It is often described at a position closer to the top of the page source than the <article> tag. Since the description is for defining the description of the web page as described above, the description of the web page is often expressed in more detail than other contents. Further, content whose position described in the page source is close to the top of the page source is likely to be displayed at a position closer to the top of the web page than content farther than that. In order to reliably convey the content of the web page to the user, there are more web pages with the main points posted at positions closer to the head than those with the main points posted at positions away from the head. Therefore, according to the present modification, the main points of the web page are compared with the case where the content is specified regardless of the position described on the page source (that is, without considering the description contents and the posting position on the web page). As a result, the partial information to be generated is more likely to represent the details of the web page. Therefore, according to the present modification, it is possible to extract a part from the web page that makes it possible to grasp the details in more detail than when the content is specified without taking the above-described consideration into consideration.

(Modification 6)
When the extracted content includes text content, the specifying unit 203 may specify the text based on the number of specific character strings (keywords) included in the text. For example, the specifying unit 203 specifies the text having the largest number of specific character strings included in the extracted text as the text satisfying the second condition. The specifying unit 203 of this modification is a function realized by the control device 21 and the storage device 22 in cooperation. The storage device 22 stores a list of specific character strings determined in advance. The control device 21 counts the number of specific character strings included in each text extracted by the extraction unit 202 for each text using a known text matching technique. The control device 21 identifies the text with the largest number as the text that satisfies the second condition.

  For example, if you have quotes that contain more text than other content texts, or if the main points of a web page are posted later in the page, a more detailed Content representing the contents of the page may not be extracted. In such a case, a specific character string representing a word of interest of the user (for example, if the gastroenterologist is a user, the name of a symptom often examined in the gastroenterology department or a commonly used medicine (Name) in advance, it becomes easier to identify content that represents a part of the web page that the user is interested in, compared to the case where content is not identified based on a specific character string. It is possible to make it easier to grasp whether or not the page has contents of interest to the user.

  In the information processing apparatus 20, a specific character string may be updated (changed, added, and deleted) by a user operation. Further, the information processing apparatus 20 may update a specific character string by the following method. First, the bookmark server device 10 extracts partial information included in the bookmark data generated by the bookmark creation operation of each user, and the order determined from the words / phrases included in the extracted partial information having the highest appearance frequency ( For example, items up to the tenth) are stored in association with the identification information of the user who performed the bookmark creation operation. When the bookmark server device 10 authenticates the user, the bookmark server device 10 transmits data of a character string indicating a phrase stored in association with the authenticated identification information to the information processing device 20. The character string indicated by the transmitted data is updated as a specific character string. This makes it easier to identify content that includes content similar to the web page indicated by the bookmark created by the user in the past, compared with the case where such updating is not performed, and as a result, the web page is of interest to the user. It is possible to make it easier to grasp whether or not the contents are contents.

(Modification 7)
The identifying unit 203 identifies one content in each of the above-described embodiments and modifications, but is not limited thereto, and a plurality of contents may be identified. For example, when the text is specified by the method described in the first embodiment, the specifying unit 203 uses the extracted text instead of specifying the extracted text having the largest index indicating the amount of text. Among these, texts that are included in a predetermined order (for example, second or third) from the largest index indicating the amount of text are specified as the text that satisfies the second condition. Further, when specifying an image by the method described in the second embodiment, the specifying unit 203 determines a predetermined image from the larger image size instead of specifying the extracted image having the largest image size. Are included as an image that satisfies the second condition.

  Further, as described in the above modification, when specifying content based on the position where the content is described in the page source (description data), the specifying unit 203 determines that the position described in the page source is the top of the page source. Instead of specifying the content closest to the page source, the content that includes the position described in the page source in the predetermined order from the closest position to the top of the page source is specified as the content that satisfies the second condition. In addition, as described in the above modification, when specifying text based on the number of specific character strings included in the text, the specifying unit 203 specifies the one having the largest number of specific character strings included in the text. Instead, texts that are included in a predetermined order starting from the one with a large number of specific character strings included in the text are specified as text that satisfies the second condition.

  FIG. 15 is a diagram illustrating an example of a bookmark in the present modification. In FIG. 15, the bookmark A3 displayed on the browser is shown. In addition to A11, A12, and A13 shown in FIG. 2, the bookmark A3 includes text A31 that is the content of the web page. The text A13 is a part of the content of the web page specified as described above, but does not always represent the content in more detail than the other content. In such a case, if the second text A31 represents the contents of the web page in more detail than other contents, the user who has viewed the bookmark A3 sees only the text A13 as the contents of the contents. It will be possible to grasp in more detail than. As described above, according to the present modification, by specifying the second (or three or more) texts, information representing the details of the content can be generated in comparison with the case where the texts are not specified. can do.

(Modification 8)
In each embodiment described above, when the specified content is text, the generation unit 204 generates information represented by text having a predetermined number of characters from the beginning of the text as partial information. May be changed. For example, the generation unit 204 may change the number of characters according to the number of specified texts. For example, the generation unit 204 sets the predetermined number of characters to 100 when there is one specified text, 50 characters when there are two, and 33 characters when there are three. Generate information. In addition, when the specifying unit 203 specifies, for example, the third to third texts with the largest amount of text, the generating unit 204 sets the predetermined number of characters to 50 characters with the largest number of texts. The third one may generate partial information with a predetermined number of characters of 25 characters each. As described above, the generation unit 204 changes the predetermined number of characters so that the total amount of text included in the partial information is the same or within a predetermined range even if the number of identified texts increases. Is desirable.

  In addition, when one text is specified by the specifying unit 203 and the text has a predetermined number of characters or more, the generating unit 204 generates partial information from the text, and if the text is less than the predetermined number of characters Alternatively, partial information may be generated by complementing a text with an insufficient number of characters from the second text. In that case, the generation unit 204 notifies the specification unit 203 that the number of characters is insufficient, and the specification unit 203 specifies the second text and supplies the second text to the generation unit 204 when the notification is received. The generation unit 204 and the specifying unit 203 repeat this notification and supply operation until the number of characters is sufficient. As a result, the generation unit 204 can always generate a bookmark in which the content is represented by a predetermined number of characters.

  In addition, when the specified content includes an image, the generation unit 204 may generate partial information by changing the size of the image. For example, in the example of FIG. 10, the generation unit 204 processes the specified image into an image of vertical 128 × horizontal 128 pixels, but when there are two specified images, for example, vertical 128 × horizontal 64 pixels. Two images may be processed, or two images of 90 × 90 pixels may be processed. As described above, the generation unit 204 increases the number of identified images so that the total file size (or the number of pixels) of the images included in the partial information is the same or within a predetermined range. It is desirable to change the size.

  If the amount of text included in the bookmark increases, the amount of bookmark data transmitted from the information processing apparatus 20 to the bookmark server apparatus 10 in step S21 shown in FIG. 9 increases, and the communication load increases. In addition, when a plurality of bookmarks are displayed on the display device 24 of the information processing apparatus 20, the area on the screen necessary for displaying one bookmark increases, so the number of bookmarks that can be displayed at a time decreases. . According to the present modification, when the number of identified texts is increased and the bookmarks represent the contents in detail as described above, an increase in communication load can be suppressed.

(Modification 9)
In addition, when the content displayed in the display mode defined by the extraction regulation information (for example, <img> tag) that satisfies the first condition includes image content, the extraction unit 202 includes those images. Further extraction may be performed from (hereinafter referred to as “extracted image”). For example, the extraction unit 202 may further extract those extracted images in which text is associated with the images. In this case, the extraction unit 202 further extracts an extracted image whose alternative text is defined by the alt attribute of the <img> tag. The alternative text is defined as a text to be displayed instead when an image cannot be displayed on a web page. In this way, images associated with alternative text are often images that are intended to be viewed by a viewer among images on a web page, compared to images that are not. According to this modification, by extracting an image associated with alternative text, the creator of the web page can extract the content of the page compared to the case of extracting an image without considering the association of the alternative text. This makes it easier to extract images that you want to show on, and as a result, you can generate bookmarks that convey more of the intent of the creator of the web page.

(Modification 10)
The extraction unit 202 may further extract, for example, an image whose ratio of the vertical length to the horizontal length of the image is included in a certain value range among the extracted images described above. The extraction unit 202 in this case is a function realized by the control device 21 as in the first embodiment. Image data is supplied to the control device 21 as data indicating the content acquired by the acquisition unit 201. The control device 21 refers to the header of the supplied image data (data representing information related to the image) to acquire the number of vertical and horizontal pixels of the image, and the vertical length relative to the horizontal length of the image from the acquired number of pixels. Calculate the ratio. The control device 21 determines whether or not the calculated ratio is included in a range of a constant value (for example, 0.5 or more and less than 5.0). 203. The control device 21 makes this determination for all the image data supplied from the acquisition unit 201. As a result, image data indicating an image in which the ratio of the vertical length to the horizontal length is within a certain range is extracted and supplied to the specifying unit 203. In this way, the extraction unit 202 performs the above-described extraction. The image becomes horizontally long as the ratio of the vertical length to the horizontal length is small. A horizontally long image is often an image used for advertisement or promotion like a banner. In addition, the larger the ratio, the longer the image becomes. However, the portrait image is often irrelevant to the contents of the web page as the landscape image. In this example, the extraction unit 202 can extract images excluding them.
Note that the extraction unit 202 may extract content whose ratio is equal to or greater than the threshold as content that satisfies the first condition. In this case, the extraction unit 202 can extract an image excluding a horizontally long image.

  In the above example, the extraction unit 202 extracts the image based on the image size, which is the ratio of the vertical length to the horizontal length of the image. However, the extraction unit 202 may perform further extraction based on the size of another image. Good. For example, the extraction unit 202 may further extract an image whose size (file size or number of pixels) is greater than or equal to a threshold value. In this case, the extraction unit 202 can extract an image excluding a small icon such as an icon. Further, the extraction unit 202 may further extract a file having a file size per pixel that is equal to or greater than a threshold value. The larger the file size per pixel, the higher the resolution of the image. Web pages often use less detailed images for less important images. In this example, the extraction unit 202 can extract an image excluding such an image.

(Modification 11)
The extraction unit 202 may further extract the above-described extracted image that has an access destination associated with the image and whose access destination domain is different from the web page. In this case, the extraction unit 202 first extracts the extracted image whose display mode is defined by the <a> tag, that is, the one having an associated access destination. Then, the extraction unit 202 compares the domain of the access destination (URL) specified by the href attribute and the access destination domain of the web page from which the content is acquired by the acquisition unit 201 among the extracted images. Then, the images that do not match are further extracted.

  According to this modification, an image associated with an access destination with a different domain is compared with an image that is not (that is, an image associated with an access destination of the same domain and an image with no access destination associated). When the content of the web page is expressed in more detail, information that expresses the content of the web page in more detail can be generated compared to the case where the content is not extracted as described above.

(Modification 12)
In each of the above-described modifications, the extraction unit 202 includes image content included in the content displayed in the display mode defined by the extraction regulation information (for example, <img> tag) that satisfies the first condition. Further, the image is further extracted, but this further extraction may be performed only when a predetermined condition is satisfied. The condition here is a condition determined to determine whether or not to change the image extraction method, and is hereinafter referred to as a “change condition”. The change condition is satisfied, for example, when the content is extracted according to the priority order as described in FIG. 14 and the text is not extracted with the priority order definition information up to a predetermined order (for example, second). As shown in the example of FIG. 14, when it is determined to increase the priority of the regulation information that defines the display mode of the content that represents the content of the web page in more detail than the other content, The fact that the text is not extracted with the prescription order information up to the order is considered to be a web page characterized by the description of the page source. For this reason, even if an image is specified based on the regulation information, an image showing the details of the web page in more detail than other images may not be specified. For this reason, when the change condition is satisfied, the extraction unit 202 further extracts an image by the method described in each of the above modifications.

(Modification 13)
The extraction unit 202 may extract content using a specifying method performed by the specifying unit 203. For example, the extraction unit 202 may extract content included in a predetermined order (for example, half or a quarter of the entire content) from the position displayed on the web page close to the top. In addition, when the acquired content includes text content, the extraction unit 202 includes the text from the largest index indicating the amount of text to the predetermined order (same as above). May be extracted. In short, the extraction unit 202 extracts all of the acquired contents that satisfy the conditions used in the above-described extraction method and identification method.

  On the contrary, the specifying unit 203 may specify the content using the extraction method performed by the extracting unit 202. For example, when the extracted content includes image content, the specifying unit 203 specifies the image associated with the text among the images. When there are a plurality of images specified in this way, the specifying unit 203 includes, for example, the position displayed on the web page that is closest to the top, or from a position close to the top to a predetermined order. You just need to identify things. In short, the specifying unit 203 specifies a predetermined number of contents (one or several) from among the extracted contents that satisfy the conditions such as those used in the extraction method and the specifying method described above. Is.

(Modification 14)
The acquisition unit 201 may acquire the regulation information and at least one content by a method different from the above-described embodiments. For example, the acquisition unit 201 stores the web page data once acquired for a predetermined period or a predetermined amount of data, and stores it when a request for a web page storing the web page data is made. The specified information and at least one or more contents are acquired from the web page data.

(Modification 15)
In addition to the information processing system such as the information processing apparatus and the bookmark service providing system 1, the present invention can also be understood as an information processing method for realizing processing performed by the information processing apparatus. The process here is, for example, a service providing process and a content extracting process shown in FIGS. 9 and 15, respectively. Further, the present invention can also be understood as a program for causing a computer such as the information processing apparatus 20 to function as each unit shown in FIG. Such a program may be provided in the form of a recording medium such as an optical disk storing the program, or may be provided in a form such that the program is downloaded to a computer via a network such as the Internet, and the program can be installed and used.
