  When the control unit receives selection information indicating any of the menu items in the menu page, the control unit acquires internal information linked to the menu item indicated by the selection information from the block information generation unit and outputs the internal information. The storage means stores, as the preference information, past selection information including information related to the menu item previously indicated by the selection information and the URL of the Web page from which the menu item is extracted, It is desirable that the extraction unit extracts the block information to be output from the plurality of block information based on the past selection information.

  According to the above invention, by using the past selection information, it is possible to determine whether or not the block created by the block information creation unit has been selected in the past. For this reason, it is possible to create a menu page that excludes the menu items of blocks that were not selected in the past (menu items that are highly likely not to be required by the user), enabling the user to quickly reach the necessary information. Become.

  The block information creating means assigns a number to each of the plurality of blocks according to a predetermined condition, and for each block, the title character string, the internal information, the number, and the Web page The block information having a position is created, the plurality of block information is stored in association with the URL of the Web page that is the basis of the plurality of block information, and the past selection information is stored in the past. The URL of the Web page from which the title character string, which is the menu item indicated by, is extracted, the title character string, the block number corresponding to the title character string, the position of the block on the Web page, The previous title character string, which is the title character string of the block with the number preceding the block, and the type of the block with the number after the block And a title character string in the past selection information among a plurality of block information in the block information creation means, and The block information related to the URL in the past selection information is extracted only when the difference between the number in the block information and the number in the past selection information is within a first predetermined value, and the block information Among a plurality of block information in the creating means, between the number in the block information having the previous title character string as the title character string and the number in the block information having the subsequent title character string as the title character string The block information related to the URL in the past selection information and the position on the Web page in the block information and the past selection information It is desirable that the difference between the position on eb page is extracted only when that are within a second predetermined value.

  Many web pages are updated over time.

  For this reason, the notation of the menu item not selected in the past may be changed to the same notation as the menu item selected in the past by the update. On the other hand, the notation of the menu item selected in the past may be changed to the notation of the menu item not selected in the past by the update. Note that the positional relationship between the blocks is unlikely to change significantly.

  According to the above-described invention, it is possible to place a menu item whose notation has been changed since it was selected in the past, together with a menu item of a block that is highly likely to be selected in the past.

  Therefore, it is possible to create a menu page excluding block information that is highly unlikely to be required by the user, and the user can quickly reach the necessary information.

Further, the storage means further stores, as the preference information, a keyword indicating the user's preference,
It is desirable that the extracting means further extracts block information having a title character string including the keyword from a plurality of block information in the block information creating means.

  The selection information storage unit 12 is an example of a storage unit, and stores preference information indicating the user's preference.

  The layout analysis unit 13 is an example of a block information creation unit, and acquires a Web page indicated by the URL input or selected by the first input unit 11 from the WWW server 19.

  The layout analysis unit 13 analyzes the layout of the Web page, divides the Web page into a plurality of blocks, and for each block, the title character string of the block and internal information (hereinafter referred to as “internal content” shown in the block). ").) Is extracted.

  The layout analysis unit 13 creates block information having a title character string and internal content for each block, and holds the block information.

  The layout analysis unit 13 sequentially holds the plurality of block information in association with the URL of the Web page that is the basis of the plurality of block information.

  For example, the layout analysis unit 13 assigns a number (hereinafter referred to as “item number”) to each of a plurality of blocks according to a predetermined condition (for example, the order of appearance in an HTML document corresponding to a Web page), and blocks. Each block information having a title character string, internal content, item number, and position on the Web page (hereinafter referred to as “block coordinates”) is created.

  The layout analysis unit 13 holds the plurality of block information in association with the URL of the Web page that is the basis of the plurality of block information.

  FIG. 2 is an explanatory diagram showing an example of block information held in the layout analysis means 13.

  The layout analysis unit 13 includes, for example, an analysis unit and a memory, and the analysis unit executes the above-described processing, and the memory stores the plurality of block information, the plurality of block information, as shown in FIG. Are stored in association with the URL of the Web page that is the basis of the block information.

  The block extraction unit 14 is an example of an extraction unit, and block information to be output (block information according to the user's preference) is selected from a plurality of pieces of block information in the layout analysis unit 13 as selection information storage unit 12. Extract using the preference information.

  The menu page creation means 15 refers to the block information extracted by the block extraction means 14, uses the title character string in the block information as a menu item, and the menu item is a hyperlink to the internal content corresponding to the menu item. Create the menu page.

  The display / read-out control means 16 is an example of a control means, and controls the output of the menu page created by the menu page creation means 15. Specifically, the display / reading control means 16 displays a menu page on the display in the output means 18 and outputs the contents shown in the menu page from the speaker in the output means 18 by voice.

  When the display / reading control means 16 receives selection information indicating any of the menu items from the second input means 17 while the menu page is being read, the display / reading control means 16 links to the menu item indicated by the selection information. The internal content to be extracted is taken out from the layout analysis means 13, and the internal content is output (displayed and read out) from the output means 18 as an internal content page.

  Note that the selection information storage unit 12 stores, as preference information, past selection information including information related to the menu item previously indicated by the selection information and the URL of the Web page from which the menu item is extracted.

  For example, the past selection information includes the URL of the Web page from which the title character string that is the menu item previously indicated by the selection information is extracted, the title character string, and the item number of the block corresponding to the title character string. And the block coordinates of the block, the previous title character string which is the title character string of the block of the item number before the block, and the item number after the block corresponding to the menu item indicated by the selection information And a post-title character string that is a title character string of the block.

  FIG. 3 is an explanatory diagram showing an example of past selection information.

  The selection information storage unit 12 further stores a keyword indicating the user's preference as the preference information.

  The block extraction unit 14 extracts block information to be output from a plurality of block information in the layout analysis unit 13 based on the past selection information.

  For example, the block extraction unit 14 has a title character string in the past selection information among a plurality of block information in the layout analysis unit 13 and is associated with the same URL as the URL in the past selection information. The block information is extracted only when the difference between the item number in the block information and the item number in the past selection information is within the first predetermined value (see FIGS. 2 and 3).

  Further, for example, the block extraction unit 14 includes, among the plurality of block information in the layout analysis unit 13, the item number in the block information having the previous title character string in the past selection information as the title character string, and the past selection information For block information having an item number between the item number in the block information having the subsequent title character string as the title character string and related to the same URL as the URL in the past selection information, Extraction is performed only when the difference between the position indicated by the block coordinates in the block information and the position indicated by the block coordinates in the past selection information is within the second predetermined value (see FIGS. 2 and 3).

  In addition, arbitrary values can be set as the first predetermined value and the second predetermined value.

  Further, the block extraction unit 14 extracts block information having a title character string including a keyword that is preference information from a plurality of block information in the layout analysis unit 13.

  FIG. 4 is a flowchart for explaining the operation of the Web content display / reading apparatus 100. The operation of the Web content display / reading apparatus 100 will be described below with reference to FIG.

  The layout analysis unit 13 acquires the URL input or selected by the first input unit 11, and acquires the Web page of the URL from the WWW server 19 (step S10).

  Subsequently, the layout analysis unit 13 analyzes the acquired web page, divides the web page into a plurality of blocks, and creates and holds block information for each block (step S11).

  For example, the layout analysis unit 13 divides the Web page into display elements (blocks) by using the structure and positional relationship of the HTML tag for the HTML document for displaying the Web page.

  The layout analysis unit 13 extracts a title character string from each block based on the HTML tag type determination rule, the style determination rule, and the content determination rule.

  As the HTML tag type determination rule, for example, the tag type is h1 to h6, the tag type is address, the tag type is em, strong, dfn, code, samp, kbd, var, cite, abbr , Not acronym, and the tag type is img.

  For example, the character string is not hidden, the character string has a background color or a background image, the width, height, and aspect ratio of the character string are not more than predetermined values, and the character string has an animation. No rule is used.

  The content determination rules include text inside the area delimited by tags, the internal text is not multiple lines, the character size is a certain value or more, and the character size is a predetermined size or less in the usage frequency in the document Is used.

  The technique for analyzing the layout of the Web page and extracting the block and the title character string is a known technique, and the details thereof are omitted.

  Subsequently, the layout analysis unit 13 assigns item numbers to each block in the order of appearance in the HTML syntax, and obtains coordinates (block coordinates) on the actual layout of the blocks.

  The layout analysis means 13 creates block information having a title character string, internal content, item number, and block coordinates for each block, and sets the plurality of block information as the source of the plurality of block information. The URL is stored in association with the URL of the Web page.

  Subsequently, the block extracting unit 13 selects the block information group created in step S11, the past selection information and the menu extraction keyword relating to the block previously read out in the Web page of the URL extracted from the selection information storage unit 12. Are used to extract a block information group to be used as a menu item of the menu page (step S12).

  As an example of the extraction condition, the following rule is applied.

From the block information group created in step S11, the block extraction means 13
(1) If there is no past selection information associated with the URL held by the layout analysis means 13 in the selection information storage means 12, all block information.
(2) Block information of a block whose title character string matches the title character string of the block included in the past selection information. However, if the difference between the item numbers of both blocks is greater than the specified value, it is excluded. This specified value can be changed as appropriate.
(3) Block information of blocks whose title character strings do not match but whose title character strings before and after the block match the previous title character string and the subsequent title character string. However, it excludes when the difference of the coordinate value of both blocks is more than a regulation value.
(4) Block information of a block in which the title character string partially matches the character string indicated by the menu extraction keyword.
A block that satisfies any of the above conditions is extracted.

  The menu page generation means 15 refers to the block information group extracted in step S12, uses the title character string of each block as the menu item name, and sets each menu item as a hyperlink to the internal content of the block corresponding to the menu item. A menu page is generated (step S13).

  When the menu page generation is completed, the display / read-out control unit 16 displays the menu page and reads out by voice (step S14).

  The display / reading control means 16 checks whether the menu item is selected by the second input means 17 using the selection information (step S15).

  In step 15, when the menu item is selected by the second input unit 17 while reading out the menu item, the display / readout control unit 16 includes the block information group stored in the layout analysis unit 13. The fact that the menu item has been selected so as to read out the menu item is registered in the block information corresponding to the selected menu item (step S17).

  The display / reading control means 16 acquires the internal content corresponding to the selected menu item from the layout analysis means 13 and creates an internal content page of the block (step S18).

  The display / reading control means 16 performs display of the internal content page of the block created in step S18 and reading by voice (step S19).

  The display / reading control means 16 checks whether or not the hyper ring in the page is selected by the second input means 17 (step S20).

  In step S20, when the second input unit 17 instructs the selection of the hyperlink in the content while the display / read-out control unit 16 is reading out the internal content page, the layout analysis unit 13 selects at that time. The block information group thus obtained is stored in the selection information storage means 12 as past selection information as shown in FIG. 3 (step S21), and the display / reading control means 16 sends the URL indicated by the hyperlink to the layout analysis means 13. The process related to the URL is repeated from the beginning.

  If the hyper ring is not selected in step 20 and the voice reading of the internal content page is completed, the display / reading control means 16 returns to the menu page display / reading process in step S14.

  The display / reading control means 16 checks whether “end” is selected by the second input means 17 (step S16).

In step 16, when the display / reading control unit 16 detects selection of “end” during or after the voice reading of the menu item, the layout analysis unit 13 displays the block information group selected at that time as a block information group. As shown in FIG. 2, it is stored in the selection information storage means 12 as past selection information (step S22). If the end is not selected in step S16, the display / read-out control means 16 returns to step 14 and repeats the menu page display / read-out process.
(Concrete example)
Next, specific examples of the present invention will be described with reference to FIGS. 5, 6, 7, 8, and 9.

  FIG. 5 is an image diagram showing an example in which the layout analysis unit 13 analyzes a Web page with a given URL and divides the Web page into block groups.

  In FIG. 5, each rectangle represents a block, and a text character string represents a title character string of a block corresponding to the text character string. Here, it is assumed that the user accesses the URL of the Web page for the first time.

  The block extraction unit 14 tries to acquire the past selection information of the corresponding URL from the selection information storage unit 12, but since this is the first access to this URL, there is no past selection information. Therefore, the block extracting means 14 extracts all block information as block information for creating menu items.

  The menu page generation means 15 refers to the block information group for creating menu items extracted by the block extraction means 14 and generates a menu page.

  FIG. 6 is an image diagram of a menu page that is used by the menu page generation unit 15 to create menu items using all block information.

  This time, the user instructed to display and read out the internal contents of the “Notice”, “September 10 topics”, “Today's weather”, and “Buy” blocks via the menu page, and select “End” .

  Each time the user selects a menu item, the display / reading control unit 16 notifies the layout analysis unit 13 that block information corresponding to the menu item has been selected.

  The layout analysis unit 13 stores the information of the block that has been displayed and read aloud in the selection information storage unit 12 as past selection information when “end” is selected or when a transition is made to a different URL.

  FIG. 7 is an image diagram of past selection information stored in the selection information storage means 12.

  Assume that a user accesses a Web page with the same URL at a later date.

  FIG. 8 is an image diagram showing an example of a result of block extraction performed by the layout analysis unit 13 from the Web page at that time.

  The block extraction unit 14 acquires past selection information and menu extraction keywords from the selection information storage unit 12.

  It is assumed that “stock price” and “news” are acquired as past selection information and menu extraction keywords shown in FIG.

  The block extraction means 14 confirms the past selection information in order.

  When the block extraction means 14 sees the block information divided by the layout analysis means 13, there is a block whose title character string is “Notification”, and its item number is the same as the item number of the past selection information. The block information of the block is extracted as the block information for the menu item.

  The “9/10 topics” block of the past selection information does not exist in the block information divided by the layout analysis means 13. However, with respect to the “9/17 Topics” block, the block coordinates are the same as “9/10 Topics” in the past selection information, and the title character strings of the preceding and following blocks are “Join” and “News”. Since they are the same, the block extracting means 14 extracts the block information of the “9/17 topics” block as the block information for the menu item.

  Since there is a block whose title character string is “Today's weather” and its item number is not significantly different from the item number of the past selection information (for example, 5 or more), the block extracting unit 14 selects the “Today's weather” block. Are extracted as block information for menu items.

  There are two blocks whose title string is “Buy”. In FIG. 8, the item number of the “Buy” block on the left side is “3”, and the item number of the “Buy” block on the right side in FIG. With respect to the “buy” block on the right side, the item number of the “buy” block on the right side is not significantly different from the item number of the past selection information (for example, 5 or more). Block information is extracted as block information for menu items.

  Further, the block extracting means 14 selects a block having a title character string partially matching the menu extraction keywords “stock price” and “news”, and the block information of the “today news” block is used as the block information for the menu item. Extract as

  The menu page generation unit 15 acquires block information extracted for the menu item from the block extraction unit 14 and generates a menu page based on the block information.

  FIG. 9 is an image diagram of the menu page generated this time. In the menu page, a menu item such as “display all” which is a hyperlink for configuring a menu page having all block information as menu items may be added.

  In this way, the number of menu items in the menu page can be reduced by using the past selection information that is block information read out in the past and the menu extraction keyword.

  As described above, the present embodiment has the following effects.

The first effect is to narrow down the menu items used for the menu page by using past selection information and menu extraction keywords that have been selected in the past and reduce the number of menu items. If this happens, the menu item of the target information can be reached quickly.
