Description

  The present invention relates to a technique for processing a web page.

  Generally, information on the WWW (World Wide Web) is described in an HTML (Hyper Text Markup Language) format. The user can display the read HTML file on the display by using a web browser. The displayed page is hereinafter referred to as a “web page”. One of the powerful functions of a web page described by HTML is a “link function”. The user can refer to a new linked web page by designating a link on a certain web page.

  For example, web pages dealing with news are often provided with links by category. More specifically, a navigation menu showing topics such as “society, economy, and international” is displayed on the news page. For example, by selecting “Society”, the user can refer to a new page in which social-related news is compiled.

  Such a navigation menu is a very convenient function for the user. However, in some cases, such a navigation menu can be a barrier to accessing the information you really want to know. As one of such cases, there is a case where information included in a web page is read out by voice. Speech reading of web pages has become a useful tool for visually impaired people, elderly people, and automobile drivers, for example. However, when a speech reading process is executed for a certain news page, there is a possibility that a navigation menu, an advertisement, etc. may be read out before the news to be known is read out. This is troublesome for a user who uses the voice reading function.

  Patent Document 1 discloses a web browser control method for the purpose of suppressing the troublesomeness of the navigation menu. According to this web browser control method, the read web page is analyzed based on the “HTML tag”, and for example, the navigation menu is handled as one block. Thereby, even when the navigation menu in a certain news page is read out, the user can skip reading out the navigation menu by executing the skip process. That is, the user does not need to wait for the unnecessary navigation menu portion to be read out, and can refer to the next item.

  Patent Document 2 discloses a speech synthesis control method. According to this technique, first, text data included in a window area displaying the document data is extracted from the document data to be output as audio. Next, the reading target is specified according to the setting contents stored in advance. Then, speech synthesis processing is performed on the specified reading target.

  Patent Document 3 discloses a document processing method for appropriately cutting out a part suitable for reading from text data in an electronic mail or HTML format. According to this document processing method, the input text data is divided into predetermined blocks according to the configuration. Next, the document structure of the obtained block is analyzed, and the block is divided into sentence units. Tag information is added to the sentence obtained according to the structure of the text data, and the sentence is structured. Based on the tag information given to the structured sentence, sentence extraction is controlled.

  A document reading system disclosed in Patent Document 4 includes a unit that divides a structured document into headings, a unit that associates headings with documents positioned below them, a text-to-speech synthesizer that converts text into speech, It consists of a plurality of audio playback units. Each heading and the sentence located below it are associated with each sound reproduction unit and reproduced.

  An object of the present invention is to provide a technique capable of automatically extracting only a part necessary for processing from a web page. In particular, an object of the present invention is to provide a technique that can automatically extract only a portion necessary for processing from a linked web page.

  Another object of the present invention is to provide a technique capable of reducing the burden on the user when a computer reads out a web page by voice.

  [Means for Solving the Problems] will be described below using the numbers and symbols used in [Best Mode for Carrying Out the Invention]. These numbers and symbols are added in parentheses in order to clarify the correspondence between the description of [Claims] and [Best Mode for Carrying Out the Invention]. However, these numbers and symbols should not be used for the interpretation of the technical scope of the invention described in [Claims].

  For example, a list of news articles may be displayed on a web page that handles news. Each item shown in the list is linked to a page on which the news text is written. When the user specifies a news article that the user wants to know in the list, the linked page is displayed. In this way, the user can know the text of the news. Here, there is a very high possibility that the text displayed in the link portion of the list matches the news title on the linked page. In the block in which the news title is displayed, the text of the news that the user wants to know is written. That is, the expression that appears in the link portion in the list can be a powerful hint for searching for information to be found on the linked page. Therefore, it is possible to automatically skip unnecessary navigation menus and advertisements by searching the link destination page for text that appears in the link portion of the list page.

  According to the present invention, a technique based on the above viewpoint is provided. Specifically, according to the present invention, there is provided a program (software product) for processing a web page, and a web page processing program for causing a computer to realize the following functions.

  In the first aspect of the present invention, the web page processing program (50) includes (A) a link portion (131, 331) indicating a link on a certain page (120, 320) displayed on the display device (70). When specified, a step of acquiring text including a link portion (131, 331) as link text (132, 332), and (B) at least part of the link text (132, 332) as a target (200) A search from the linked pages (150, 350), which is a page specified by the link, and (C) a target (200) retrieved from the block group included in the linked pages (150, 350). Selecting a block as a target block (TB).

  The web page processing program (50) further causes the computer to execute (D) a step of reading the content included in the target block (TB). Or this web page processing program (50) makes a computer perform the step which reads out the content displayed below the start position of (D) target block (TB). These functions are useful for visually impaired people, elderly people, and automobile drivers. Alternatively, the web page processing program (50) causes the computer to execute a step of (D) enlarging the target block (TB) and displaying it on the display device (70). These functions are useful for the visually impaired and the elderly. Or this web page processing program (50) makes a computer perform the step which preserve | saves the data corresponding to (D) target block (TB) in a memory | storage device (20). This makes it possible to easily create a scrapbook (23) such as a news article.

  In the step (A), only the link portion (131, 331) may be acquired as the link text (132, 332). In the step (A), a sentence including the link portions (131, 331) may be acquired as the link text (132, 332).

  The step (B) may include a step of (b1) searching from the linked pages (150, 350) with all the link texts (132, 332) as targets (200). When the target (200) is not found in this (b1) step, the above (B) step is (b2) at least one word constituting the link text (132, 332) from the link text (132, 332). And (b3) searching from the linked pages (150, 350) using the extracted word as the target (200). When the prohibited word designated by the user is registered in the storage device (20), in the step (b2), by referring to the registered prohibited word, words other than the prohibited word are linked text (132, 332). ).

  Alternatively, when the prohibited word designated by the user is registered in the storage device (20), the step (B) performs the link by referring to the prohibited word registered in the (b1) storage device (20). A step of extracting words other than the prohibited words among the words included in the text (132, 332); and (b2) a step of searching from the linked pages (150, 350) using the extracted word as a target (200). And may be included.

  When a plurality of blocks in the block group included in the linked page (150, 350) includes the target (200), in the step (C), the linked page (150, 350) among the plurality of blocks. May be selected as the target block (TB). Alternatively, a block designated by the user among the plurality of blocks may be selected as the target block (TB). Alternatively, the step (C) includes (c1) a step of selecting a plurality of blocks in order as the target block (TB), and (c2) skipping the selected target block (TB) according to the user's specification. The step of performing may be included.

  The web page processing program (50) further associates (E) information related to the linked pages (150, 350) with the position information of the target block (TB) selected in the step (C). In addition, the step of storing in the storage device (20) may be executed by a computer.

  The information related to the link destination page (150, 350) is, for example, the address of the link destination page (150, 350). When the address of the same linked page (150, 350) is designated again, the web page processing program (50) stores (F) the positional information associated with the linked page (150, 350) in the storage device. The step of reading from (20) and the step of (G) selecting the block at the position indicated by the position information as the target block (TB) from the linked pages (150, 350) are executed by the computer. When another address having a common part with the address of the linked page (150, 350) is designated, the web page processing program (50) corresponds to (F) the linked page (150, 350). A step of reading the attached position information from the storage device (20); and (G) selecting a block at a position indicated by the position information as a target block (TB) from another page specified by the other address. Causing the computer to execute the steps.

  The information related to the linked pages (150, 350) may be the address of the certain page (120, 320) (link source page). When another link included in the link source page is designated, the web page processing program (50) reads (F) the position information associated with the link source page from the storage device (20). (G) causing the computer to execute a step of selecting a block at a position indicated by position information as a target block (TB) from another page specified by the other link.

  In the second aspect of the present invention, the web page processing program (50) includes: (AA) searching for a word designated by the user from the page displayed on the display device (70); A step of selecting a block including the searched word as a target block (TB) from the included block group and (CC) reading out the content included in the target block (TB) are executed by the computer.

  When a plurality of blocks in the block group include the word, the block displayed at the top of the page among the plurality of blocks is selected as the target block (TB) in the (BB) step. Good. Moreover, the block designated by the user among the plurality of blocks may be selected as the target block (TB). Alternatively, in the (BB) step, (bb1) a step of selecting a plurality of blocks in order as a target block (TB), and (bb2) the selected target block (TB) is skipped according to the user's specification. Steps may be included.

  According to the present invention, it is possible to automatically extract only a part necessary for processing from a web page. In particular, according to the present invention, it is possible to automatically extract only a portion necessary for processing from a linked web page. Thereby, for example, when a computer reads out a web page by voice, it is possible to reduce the burden on the user.

  A web page processing system and a web page processing program according to the present invention will be described with reference to the accompanying drawings.

  FIG. 1 shows an example of a certain web page. This web page is the web page of a site that handles news. A page 120 is displayed in a predetermined area of the browser screen 110. The page 120 includes a navigation menu and an advertisement, and can be divided into a plurality of blocks (block groups) B1 to B6 based on the contents. A general navigation menu such as “weather, dictionary, map, guidance, HOME” is displayed in the block B1. An advertisement is displayed in the block B2. In the block B3, a navigation menu related to news such as “society, economy, politics, international, sports, science” is displayed. An advertisement is displayed in block B4. In block B5, a list of feature articles is displayed. In block B6, a list of social articles is displayed. As shown in this example, a “block” is defined as “one block on a page defined by a frame, ruled line, HTML tag, paragraph, etc.”.

  In block B6, a list of articles is displayed, and more specifically, news headlines such as “Distribution of district court, patent infringement recognized” and “Company N, release new personal computer” are displayed. Each heading is associated with a link, and each heading is underlined to indicate a link. For example, a link 130a is associated with the heading “Local court decision, patent infringement recognized”, and a link 130b is associated with the heading “Company N, release new personal computer”. This link function is one of the powerful functions of HTML. When the user designates a link using the pointer 140, the link destination page designated by the link is displayed in the block B6.

  FIG. 2 shows a link destination page 150 designated by the link 130a. In the block B6 of the linked page 150, the full text of the news corresponding to the designated headline is displayed. Specifically, the detailed content of the news is displayed after the title 160 “Local court decision, patent infringement recognized”. The information that the user wants to know is included in this block B6, not in the other blocks B1 to B5. Therefore, for example, when the link destination page 150 is read out by the computer, the other blocks B1 to B5 may be excluded from the reading target. Only block B6 needs to be selected as the target (target block TB).

  The inventors of the present application agree that the news title 160 on the linked page 150 (“dismissal for district court decision, patent infringement”) matches the headline on the link source page 120 (“decision on district court decision, patent infringement”). Pay attention. In general, there is a strong correlation between the text displayed in the link portion and the information desired to be known on the linked page. It is very likely that the text displayed in the link portion is information to be searched on the linked page. That is, the expression that appears in the link portion can be a powerful hint for searching for information to be found on the linked page. The inventors of the present application focused on this tendency. In the example shown in FIG. 1 and FIG. 2, it is possible to automatically extract the block B6 as the target block TB by searching the link destination page 150 for the text appearing on the link 130a. Blocks B1 to B5 in which unnecessary navigation menus and advertisements are displayed are automatically excluded from the target.

  A specific configuration and algorithm for realizing the above-described idea will be described below.

  FIG. 3 is a block diagram showing the configuration of the web page processing system according to the present invention. The web page processing system 1 includes an arithmetic processing device 10, a storage device 20, a network interface 30, a web browser 40, a web page processing program 50, an input device 60, a display device 70, and an audio output device 80.

  The arithmetic processing device 10 includes a CPU and can access each device. An HDD is exemplified as the storage device 20. The storage device 20 stores history data 21, prohibited word data 22, scrapbook data 23, and the like, which will be described later. The web page processing system 1 can be connected to the Internet 100 via a network interface 30. Examples of the input device 60 include a mouse and a keyboard. An example of the display device 70 is a liquid crystal display. As the audio output device 80, a speaker is exemplified.

  The web browser 40 is a computer program (software product) executed by the arithmetic processing device 10. Data (HTML file) read via the Internet 100 is processed by the web browser 40, and web pages (120, 150) corresponding to the data are displayed on the display device 70. The user can specify a link in the displayed web page by using the input device 60.

  The web page processing program 50 is a computer program (software product) executed by the arithmetic processing device 10. The web page processing program 50 includes a target selection unit 51 that extracts a target block TB from a web page, and a text-to-speech conversion unit 52 that converts text data into speech data. The web page processing program 50 provides functions described below in cooperation with the web browser 40.

(First embodiment)
FIG. 4 is a flowchart showing a web page processing method according to the first embodiment of the present invention. The operation of the web page processing system 1 for the example shown in FIGS. 1 and 2 will be described with reference to FIGS.

  Assume that the page 120 shown in FIG. 1 is displayed on the display device 70. First, the user moves the pointer 140 displayed on the page 120 by using the input device 60, and designates a news headline (link) to be viewed (step S1). For example, assume that the link 130a is designated. As shown in FIG. 5, the portion indicated by the link 130 a is particularly referred to as a “link portion 131”. That is, the link part 131 can be defined as a part associated with a hyperlink. On the display device 70, this link portion 131 (“local court decision, patent infringement recognized”) is often underlined.

  Next, the target selection unit 51 of the web page processing program 50 determines whether or not there is text in the link portion 131 (step S2). In this example, there is text in the link portion 131 (step S2; Yes). In this case, the target selection unit 51 acquires text including at least the link portion 131 as “link text 132” (step S3). As shown in FIG. 5, in the present embodiment, it is assumed that the link portion 131 and the link text 132 match. The target selection unit 51 acquires the entire link portion 131 (“local court decision, patent infringement recognized”) as the link text 132.

  Next, the web browser 40 executes a normal link function (step S4). As a result, the link destination page 150 is displayed on the display device 70. Next, the target selection unit 51 of the web page processing program 50 performs a structural analysis of the linked page 150 (step S5). Specifically, the target selection unit 51 extracts the block groups B1 to B6 constituting the linked page 150 based on the HTML tag. Moreover, the target selection part 51 may analyze arrangement | positioning of these block groups B1-B6. Next, the target selection unit 51 extracts a block to be processed as a target block TB from the block groups B1 to B6 included in the link destination page 150 (step S10).

  FIG. 6 is a flowchart showing the details of step S10 in more detail. First, “search target 200” is determined based on the link text 132 (step S11). In step S <b> 11, at least a part of the link text 132 may be determined as the search target 200. As shown in FIG. 5, in the present embodiment, it is assumed that all of the link text 132 (“local court decision, patent infringement recognized”) is adopted as the search target 200. Next, the search for the search target 200 is executed within the link destination page 150 (step S12).

  Next, it is determined whether or not the search target 200 exists in the link destination page 150 (step S13). In the present embodiment, the news title 160 included in the block B 6 (“local court decision, patent infringement recognized”) matches the search target 200. Therefore, the block B6 is selected as the target block TB (step S14). In this manner, a portion corresponding to the search target 200 is searched in the link destination page 150, and a block including the corresponding portion is extracted. Thereafter, step S100 is executed.

  If there are a plurality of relevant portions (corresponding blocks) in the linked page 150, the user is asked whether or not to perform selection processing (step S15). Whether the user performs the selection process may be set in advance. When the user performs the selection process (step S15; Yes), the user selects a desired block from a plurality of corresponding blocks by using the input device 60. The target selection unit 51 extracts the block selected by the user as the target block TB (step S16). When the user does not perform the selection process (step S15; No), the target selection unit 51 determines the target block TB according to a predetermined rule. For example, among the plurality of corresponding blocks, the block displayed at the top of the linked page 150 is selected as the target block TB (step S17). Thereafter, step S100 is executed.

  Further, there may be a case where the corresponding block does not exist in the link destination page 150. For example, it is assumed that the title 160 is not displayed on the link destination page 150 shown in FIG. In that case, the target selection unit 51 executes syntax analysis of the current search target 200 (link text 132) (step S21). The current search target 200, which is a sentence “local court decision, accepts patent infringement”, includes element words such as “district court decision” and “patent infringement”. At this time, the target selection unit 51 sets any element word as a new search target 200 (step S22). For example, the element word “patent infringement” is set in the new search target 200. As described above, the target selection unit 51 extracts at least one element word constituting the search target 200 and determines the extracted element word as a new search target 200. Thereafter, the processing after step S12 is executed again. When the new search target 200 does not exist in the linked page 150 (step S20; Yes), the user designates one block from the plurality of blocks B1 to B6 as the target block TB by using the input device 60. (Step S23). Thereafter, step S100 is executed.

  Element words that should not be extracted from the search target 200 may be registered in advance as “prohibited words”. Examples of prohibited words include particles, “here”, “click”, and the like. The user can designate these prohibited words in advance. The prohibited word data 22 indicating the prohibited words is stored in advance in the storage device 20 (see FIG. 3). In this case, in steps S <b> 21 and S <b> 22, the target selection unit 51 refers to the prohibited word data 22 stored in the storage device 20 and sets element words other than the registered prohibited words as a new search target 200. . Thereby, the search accuracy of the search target 200 is improved.

  Further, in step S2 shown in FIG. 4, when there is no text in the link portion 131 (step S2; No), the web browser 40 executes a normal link function (step S6). As a result, the link destination page 150 is displayed on the display device 70. The user selects the target block TB from the linked page 150 by using the input device 60 (step S7). Thereafter, step S100 is executed.

  After the target block TB is automatically determined by the process as described above or designated by the user, step S100 is executed (see FIG. 4). In step S100, for example, the contents included in the target block TB are read out by the computer. Specifically, the text-to-speech conversion unit 52 of the web page processing program 50 converts text data included in the target block TB into speech data. The obtained audio data is processed by the audio output device 80. In this way, the contents of the target block TB are read out by voice. That is, the navigation menu (blocks B1 and B3) and the advertisement (block B2) shown in FIG. 2 are not read out, and the contents of the block B6 are automatically read out from the beginning. Therefore, bothering is eliminated and the burden on the user is reduced.

  In step S100, only the contents included in the target block TB may be read out. Alternatively, not only the target block TB but also a block following the target block TB may be read out. That is, all the text displayed below the start position (news title 160) of the target block TB may be read out. Further, the position where the reading process ends may be designated in advance by the user. For example, in the case of a news page, as shown in FIG. 2, the date may be written at the end of the news text. If this date information is registered in advance as the end mark 170, the voice reading process ends at the position of the end mark 170. Examples of the end mark 170 include a newspaper company name, a reporter name, a ruled line, and the like in addition to the date.

  As a result of step S12, when the search target 200 exists in a plurality of blocks included in the link destination page 150, the contents included in each of the plurality of blocks may be read out in order. When the content read out is not what the user desires, the user can instruct skipping. When skipping is instructed, reading of contents included in the next block starts. In order to realize such processing, the target selection unit 51 may select the plurality of blocks one by one as the target block TB in order. When the user instructs to skip, the target selection unit 51 may skip the current target block TB and set the next block as a new target block TB.

  Furthermore, the present invention can be applied to other than the speech reading process of the web page. For example, the target block TB extracted as described above may be enlarged and displayed on the display device 70 in step S100. This function is useful for visually impaired and elderly people. In step S100, data corresponding to the target block TB may be stored in the storage device 20 as the scrapbook data 23. This makes it possible to easily create a scrapbook such as a news article. As described above, the web page processing program 50 according to the present invention can be applied to all operations that require extracting a part from a web page.

  According to the present invention, it is possible to automatically extract only a part necessary for processing from a web page. In particular, according to the present invention, it is possible to automatically extract only a portion necessary for processing from a linked web page. Thereby, for example, when a computer reads out a web page by voice, it is possible to reduce the burden on the user.

(Second Embodiment)
FIG. 7 is a diagram for explaining a web page processing method according to the second embodiment of the present invention. As shown in FIG. 7, in the present embodiment, it is assumed that the link portion 131 includes a date and is expressed as “local court decision, patent infringement recognized (04/01 21:58)”. At this time, the same part as the link part 131 is acquired as the link text 132 in step S3 shown in FIG. In this case, it is preferable that the date portion is excluded from the search target 200.

  Therefore, according to the present embodiment, in step S <b> 11 shown in FIG. 6, the target selection unit 51 determines a part of the link text 132 as the search target 200. In order to realize this function, the target selection unit 51 may be programmed so as to determine the search target 200 by excluding the parentheses at the end of the link text 132. Except for step S11, processing similar to the processing in the first embodiment is executed. Thereby, the same effect as that of the first embodiment can be obtained.

(Third embodiment)
According to the third embodiment of the present invention, after the target block TB is extracted from the link destination page 150, the position of the extracted target block TB is stored in the storage device 20. Thereby, when the linked page 150 is accessed again or when a web page having the same configuration as the linked page 150 is accessed, the target block TB can be quickly and easily referred to by referring to the position information. Can be extracted.

  FIG. 8 is a flowchart showing a web page processing method according to the third embodiment of the present invention. According to the present embodiment, steps S1 to S5 are executed as in the first or second embodiment (see FIG. 4). Next, the target selection unit 51 of the web page processing program 50 refers to the history data 21 stored in the storage device 20 (step S30).

  FIG. 9 is a conceptual diagram showing the contents of the history data 21 according to the present invention. In the history data 21, information related to the link destination page and position information of the target block TB extracted (selected) in the past in the link destination page are stored in association with each other. The information related to the linked page is, for example, the address of the linked page 150. For example, it is assumed that the address (URL) designated by the link 130a shown in FIG. 1 is “http://A.com/.../0401/15.html”. Once the target block TB is extracted in the page specified by the address (link destination page 150), the address is associated with the extracted position information P1 of the target block TB as shown in FIG. And saved as history data 21.

  Further, it is assumed that the address (URL) designated by the link 130b shown in FIG. 1 is “http://A.com/.../0401/17.html”. Once the target block TB is extracted from the page specified by the address, the address and the position information P1 of the extracted target block TB are associated with each other and stored as history data 21 as shown in FIG. Is done.

  Here, it should be noted that the position information for the address of the link 130a is the same as the position information for the address of the link 130b. In the news pages shown in FIGS. 1 and 2, the basic configuration of each linked page is often the same. That is, the positional relationship between the block groups B1 to B6 does not change, and only the content displayed in the block B6 often changes. Therefore, as for the history data 21 related to a certain news page, as shown in FIG. 9, only the address of the top page or the link source page (http://A.com/) and the position information P1 of the target block TB are sufficient. There is a possibility. That is, the information related to the link destination page may be the address of the top page or the link source page.

  Further, when the address specified by the link 130a and the address 130 specified by the link 130b are compared, the path portion is common and only the file name is different. Therefore, when the link 130b is designated, the position information P1 associated with the address of the link 130a may be referred to. More generally, when a certain link is designated, position information associated with an address having a common part with the address of the link may be referred to.

  According to the present embodiment, when a certain link is designated, it is checked whether information related to the designated address (hereinafter referred to as a designated address) is already registered in the history data 21. (Step S31). For example, when the link 130b is designated, the designated address itself (http://A.com/.../0401/17.html) may be retrieved from the history data 21. Alternatively, an address (http://A.com/.../0401/15.html) having a common part with the designated address may be searched from the history data 21. Alternatively, the address (http://A.com/) of the link source page 120 may be searched from the history data 21.

  When information related to the specified address is registered in the history data 21 (step S31; Yes), position information P1 associated with the related information is read. That is, the target selection unit 51 acquires the position information P1 of the target block TB extracted in the past (step S32). Next, the target selection unit 51 selects the block at the position indicated by the position information P1 from the link destination page as the current target block TB (step S33). Thereby, it is possible to reduce the time required for selecting the target block TB. Thereafter, the above-described step S100 is executed, and the history data 21 is updated (step S34).

  When the information related to the designated address is not yet registered in the history data 21 (step S31; No), the above-described step S10 (see FIG. 6) is executed. Thereafter, the above-described step S100 is executed, and the history data 21 is updated (step S34).

  As described above, according to the present embodiment, the same effects as those of the first and second embodiments can be obtained. Furthermore, according to the present embodiment, as an additional effect, there is an effect that the time required for selecting the target block TB is reduced. This embodiment is particularly effective when the address of the article page changes as in the news page, but the position where the article text is displayed does not change.

(Fourth embodiment)
The present invention is not limited to news pages. FIG. 10 shows an example of a web page of a company that sells a certain product. A page 320 is displayed in a predetermined area of the browser screen 310. The page 320 includes a navigation menu and an advertisement, and can be divided into a plurality of blocks (block groups) B1 to B5 based on the contents. The company name is displayed in the block B1. In block B2, a navigation menu such as “Home, Solution, Product Information, Topics, Support” is displayed. An advertisement is displayed in the block B3. Text and images are displayed in the block B4. A menu is displayed in block B5.

  In block B4, a summary explanation for a certain product is displayed, and it is assumed that a sentence “Please see here for the operating environment of this product.” Is displayed. Further, it is assumed that the link 330 is associated with the word “here” in the sentence. For example, the word “here” is underlined to indicate to the user that the part is a link. When the user designates the link 330 using the pointer 340, the link destination page designated by the link 330 is displayed.

  FIG. 11 shows a linked page 350 designated by the link 330. In the link destination page 350, the product name is displayed in block B6, the operating environment is displayed in itemized form in block B7, and the table is displayed in block B8. As shown in this example, a “block” can also be defined as “one chunk on a page defined by an HTML tag, a table, a cell, or the like”. Information that the user wants to know is included in block B7. Therefore, for example, when the linked page 350 is read by the computer, the other blocks B1 to B6 and B8 may be excluded from the reading target. Only block B7 needs to be selected as the target (target block TB).

  Web page processing according to the present embodiment is substantially the same as that of the first embodiment (see FIG. 4). Now, assume that the page 320 shown in FIG. 10 is displayed on the display device 70. First, the user moves the pointer 340 displayed on the page 320 by using the input device 60, and designates the link 330 (step S1). As shown in FIG. 12, in this example, the link portion 331 is “here”. Next, the target selection unit 51 of the web page processing program 50 determines whether or not there is text in the link portion 331 (step S2). In this example, there is text in the link portion 331 (step S2; Yes). In this case, the target selection unit 51 acquires text including at least the link portion 331 as link text 332 (step S3). Specifically, as illustrated in FIG. 12, the target selection unit 51 acquires a sentence including the link portion 331 (“Please see here for the operating environment of this product”) as the link text 332.

  Next, the web browser 40 executes a normal link function (step S4). As a result, the link destination page 350 is displayed on the display device 70. Next, the target selection unit 51 of the web page processing program 50 performs a structural analysis of the linked page 350 (step S5). Specifically, the target selection unit 51 extracts the block groups B1 to B8 constituting the link destination page 350 based on the HTML tag. Moreover, the target selection part 51 may analyze arrangement | positioning of these block groups B1-B8. Next, the target selection unit 51 extracts a block to be processed as a target block TB from the block groups B1 to B8 included in the link destination page 350 (step S10).

  FIG. 13 is a flowchart showing the details of step S10 according to the present embodiment in more detail. First, the target selection unit 51 executes syntax analysis of the link text 332 and determines an element word constituting the link text 332 as the search target 200 (step S41). For example, in the present example, the link text 332 “Please see here for the operating environment of this product” includes element words such as “This product” and “Operating environment”. At this time, the target selection unit 51 sets any element word as the search target 200. For example, as shown in FIG. 12, the element word “operating environment” is set in the search target 200. As described above, the target selection unit 51 extracts at least one element word constituting the link text 332 and determines the extracted element word as the search target 200.

  Here, element words that should not be extracted from the search target 200 may be registered in advance as “prohibited words”. Examples of prohibited words include particles, “here”, “this product”, and the like. The user can designate these prohibited words in advance. The prohibited word data 22 indicating the prohibited words is stored in advance in the storage device 20 (see FIG. 3). In this case, in step S <b> 41, the target selection unit 51 refers to the prohibited word data 22 stored in the storage device 20 and sets element words other than the registered prohibited words as the search target 200. Thereby, the search accuracy of the search target 200 is improved.

  Next, the search for the search target 200 is executed in the link destination page 350 (step S42).

  Next, it is determined whether or not the search target 200 exists in the link destination page 350 (step S43). In the present embodiment, the text (“operating environment”) included in the block B 7 matches the search target 200. Therefore, the block B7 is selected as the target block TB (step S44). In this way, a portion corresponding to the search target 200 is searched in the link destination page 350, and a block including the corresponding portion is extracted. Thereafter, step S100 is executed.

  If there are a plurality of relevant portions (corresponding blocks) in the linked page 350, the user is asked whether or not to perform a selection process (step S45). Whether the user performs the selection process may be set in advance. When the user performs a selection process (step S45; Yes), the user selects a desired block from a plurality of corresponding blocks by using the input device 60. The target selection unit 51 extracts the block selected by the user as the target block TB (step S46). When the user does not perform the selection process (step S45; No), the target selection unit 51 determines the target block TB according to a predetermined rule. For example, among the plurality of corresponding blocks, the block displayed at the top of the linked page 350 is selected as the target block TB (step S47). Thereafter, step S100 is executed.

  Further, there may be a case where the corresponding block does not exist in the link destination page 350. In this case, the user designates one block from the plurality of blocks B1 to B8 as the target block TB by using the input device 60 (step S48). Thereafter, step S100 is executed.

  Step S100 is executed after the target block TB is automatically determined by the processing as described above, or after the user designates it. This step S100 is the same as that of the first embodiment. That is, the contents included in the target block TB are read out by the computer. Thereby, the navigation menu and the advertisement are not read out, and the contents of the block B7 are automatically read out from the beginning. Therefore, bothering is eliminated and the burden on the user is reduced. As a result of step S42, when the search target 200 exists in a plurality of blocks, the contents included in each of the plurality of blocks may be read out in order. When the content read out is not what the user desires, the user can instruct skipping. When skipping is instructed, reading of contents included in the next block starts.

  Further, the extracted target block TB may be enlarged and displayed on the display device 70 in step S100. This function is useful for visually impaired and elderly people. Further, data corresponding to the target block TB may be stored in the storage device 20 as the scrapbook data 23 in step S100. As described above, the web page processing program 50 according to the present invention can be applied to all operations that require extracting a part from a web page.

  According to the present invention, it is possible to automatically extract only a part necessary for processing from a web page. In particular, according to the present invention, it is possible to automatically extract only a portion necessary for processing from a linked web page. Thereby, for example, when a computer reads out a web page by voice, it is possible to reduce the burden on the user.

(Fifth embodiment)
In the fourth embodiment, the history data 21 stored in the storage device 20 may be referred to. The processing in that case is the same as that in the third embodiment (see FIGS. 8 and 9). As a result, the same effect as in the fourth embodiment can be obtained, and an additional effect that the time required for selecting the target block TB can be reduced.

(Sixth embodiment)
FIG. 14 is a flowchart showing a web page processing method according to the sixth embodiment of the present invention. In the present embodiment, it is assumed that a certain web page is displayed on the display device 70. First, the user uses the input device 60 to input a search word that is a search target (step S51). Next, the search word is searched for in the displayed web page (step S52).

  Next, it is determined whether or not the search word exists in the web page (step S53). When one search word is included in the web page, a block including the search word is selected as the target block TB (step S54). In this manner, a portion corresponding to the search word is searched in the web page, and a block including the corresponding portion is extracted. Thereafter, step S100 is executed.

  When a plurality of corresponding portions (corresponding blocks) are included in the web page, the user is asked whether to perform selection processing (step S55). Whether the user performs the selection process may be set in advance. When the user performs a selection process (step S55; Yes), the user selects a desired block from a plurality of corresponding blocks by using the input device 60. The target selection unit 51 extracts the block selected by the user as the target block TB (step S56). When the user does not perform the selection process (step S55; No), the target selection unit 51 determines the target block TB according to a predetermined rule. For example, the block displayed at the top of the web page among the plurality of corresponding blocks is selected as the target block TB (step S57). Thereafter, step S100 is executed.

  Also, there may be a case where the corresponding block does not exist in the web page. In this case, the user designates one block as the target block TB by using the input device 60 (step S58). Thereafter, step S100 is executed.

  Step S100 is executed after the target block TB is automatically determined by the processing as described above, or after the user designates it. This step S100 is the same as that of the first embodiment. That is, the contents included in the target block TB are read out by the computer. Further, as a result of step S52, when search words exist in a plurality of blocks, the contents included in each of the plurality of blocks may be read out in order. When the content read out is not what the user desires, the user can instruct skipping. When skipping is instructed, reading of contents included in the next block starts.

  Further, the extracted target block TB may be enlarged and displayed on the display device 70 in step S100. This function is useful for visually impaired and elderly people. Further, data corresponding to the target block TB may be stored in the storage device 20 as the scrapbook data 23 in step S100. As described above, the web page processing program 50 according to the present invention can be applied to all operations that require extracting a part from a web page.
