Description

  The present invention relates to a program, an apparatus, and a method for creating a link from one web page to another web page.

  As is well known, Wikipedia (trademark of Wikimedia Foundation) is a service that publishes an encyclopedia with unlimited editing rights to an unspecified number of users via the Internet. A function of making certain hypertext data editable on a web browser is provided (see Non-Patent Document 1). In this Wikipedia, when an editor edits hypertext data, if a link pattern (a specific syntax such as sandwiching between double square brackets) is applied to words in the hypertext data, the hypertext data When the web page is displayed based on the above, the phrase is displayed as a link button to the web page explaining the meaning of the phrase. However, the linked web page is a web page in the Wikipedia website, and is not linked to the web page of another website explaining the meaning of the phrase.

  As is well known, the POP dictionary service provides a function of displaying a pop-up window in which the meaning of a word is described when a mouse pointer is placed on any word on the web page. Patent Document 2). In this POP dictionary service, when a URL [Uniform Resource Locator] is designated by a user via a web browser, the POP dictionary engine analyzes a text in the web page data and extracts a headword. The dictionary information (text explaining the meaning) corresponding to each extracted headword is acquired from the dictionary database, and the acquired dictionary information is added to the web page data and delivered to the web browser. When the mouse pointer is placed on any word on the web page displayed based on the delivered web page data, the web browser corresponds to the word from the dictionary information added to the web page data. Retrieve dictionary information and display pop-up window. However, in the pop-up window, only the meaning of the word / phrase is described, and a link button to another web page is not created.

  In this way, neither the Wikipedia nor the POP dictionary can move from the web page that was initially viewed to the web page of another website. However, there is a possibility that a description better than the description in the Wikipedia or POP dictionary may be found on the web page of another website. You should also be able to navigate to the web page.

  There is a web annotation technique as a technique for allowing a person other than the creator of the web page data to link to an arbitrary web page. In this web annotation, an annotation server is prepared on the network. The user installs an annotation program as an extended function in the web browser of his computer. In addition, when the user performs an operation for pasting arbitrary character information on an arbitrary portion of an arbitrary web page, the URL of the web page, the position information of the portion on the web page, The character information to be pasted at the location is registered in the annotation server as annotation data. After that, when the user or another viewer accesses the same web page on the web browser having the annotation function, the web browser acquires web page data from the web server and sets the URL of the web page. Acquire corresponding annotation data from the annotation server. Then, based on the position information in the acquired annotation data, the web browser specifies the position where the character information in the web page data is to be incorporated, and embeds the character information in the acquired annotation data at the specified position. The web page is displayed based on the web page data in which the character information is embedded. In this web annotation technology, the character information to be embedded in the web page data as annotation is generally to change the information for displaying a pop-up window opened separately from the web page and the display form of the character string at that location. The tag information is used. Here, if the character information of this annotation is used as a link tag, a link to a web page of another website can be put on an arbitrary web page even if it is not a web page data creator (for example, patent document). 1).

  In this way, the user registers, for an item (word or image) in a certain web page, an annotation containing the link tag to the web page describing the content related to the item in the annotation server. Then, when the user or other viewers display the web page after that, the item in the web page contains the content related to the item. A link button to is created as an annotation.

  However, when web annotation technology is used in this way, the user moves to the web page where the content related to the item is described through the link button set as the annotation for the item in the web page. However, the top of the destination web page is always displayed, so if there is a part related to the item in the destination web page other than the top of the page, the user , You must search the part related to the item by operating the scroll box.

  The present invention has been made in view of the above-described conventional circumstances, and the problem is that a link button to a web page in which contents related to the item are described for an item in a certain web page. When it is set as a web annotation, even when moving to the web page through the link button, it is not necessary to search the web page for the content related to the item. is there.

  The link creation program devised to solve the above-described problem is the first data for acquiring the web page data when the computer receives the first location information specifying the location of any web page data. An acquisition means, a search means for searching for an item satisfying a predetermined condition from the web page data acquired by the first data acquisition means, and when the search means searches for an item satisfying the predetermined condition, a fragment is extracted from the item. In addition to selection, fragment designation information including a unique fragment identifier, location information of the web page data acquired by the first data acquisition means, and position information for specifying the position of the item in the web page data A first generation means for generating the first annotation data including an arbitrary web page data When the second location information for specifying the URL is received, the second data acquisition means for acquiring the web page data, and the item searched for by the search means from the web page data acquired by the second data acquisition means Search means for searching for related items, and a link tag including first location information to which a fragment identifier included in fragment designation information corresponding to an item detected by the search means in the first annotation data is added; Second generation means for generating second annotation data including the location information of the web page data acquired by the second data acquisition means and position information for specifying the position of the item in the web page data It is characterized by functioning as

  With this configuration, when the first location information is input, the computer can find an item satisfying a predetermined condition from the web page data specified by the first location information. It operates to generate annotation data including fragment designation information including a unique fragment identifier, first location information, and position information for the item. In addition, when the second location information is input, the computer detects an item related to the item found from the web page data from the web page data specified by the second location information. When it is possible, it operates to generate annotation data including the link tag including the first location information to which the fragment identifier is added, the second location information, and the position information.

  As a result, when the user designates the second location information and instructs the web browser to display the web page to the web browser having the annotation display function, the location of the web browser is specified by the second location information. Web page data to be acquired is acquired from the Web server, and annotation data including the second location information is acquired. Thereafter, the web browser embeds a link tag including the first location information to which the fragment identifier is added at the position specified by the position information in the annotation data in the web page data, and then the link tag A web page is displayed based on the web page data in which is embedded.

  Then, when the user moves from the item linked to on the web page to the link destination, the web browser has the web page data whose location is specified by the first location information in the link tag. Is acquired from the web server, and annotation data including the first location information is acquired. Thereafter, the web browser embeds fragment designation information at the position specified by the position information in the annotation data in the web page data, and then, based on the web page data in which the fragment designation information is embedded, Display the page. At this time, the web browser uses the fragment identifier added to the first location information in the link tag so that the fragment specified by the tag including the fragment identifier is headed. Display the page.

  The above operation is realized by installing the above-described link creation program in a computer. However, the link creation program may be installed in a computer through a computer-readable medium or downloaded through a network. May be installed on the computer.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

  However, before that, definitions of terms used in this specification will be explained for the understanding of the following explanation.

  First, as is well known, it may be possible to move (jump) from one part of a web page to another web page associated with that web page. In this way, associating two web pages so that they can move from one to the other is expressed as “link”. The link requires a link starting point as a movement source and a link end point as a movement destination.

  The link starting point is a hyperlink that is marked up in the web page by embedding a specific tag (a tag of the “a” element having an href attribute in HTML [HyperText Markup Language]) in the web page data. When the hyperlink is clicked, the user can move (jump) to the web page specified in the specific tag.

  On the other hand, the link end point means a fragment in this specification. A fragment refers to a specific place in a web page, such as the beginning of a specific paragraph or the location of a specific character string. As will be described later, the fragment is defined by embedding specific information in the web page data. The specific information is expressed as a “fragment identifier” because it is used to define a fragment and to distinguish a plurality of fragments from each other.

  Next, in order to facilitate understanding of the following description, an outline of the flow of processing will be described.

  In the computer network system according to the present embodiment described below, processing executed to obtain the effect is divided into two phases. Although both will be described later in detail, the first phase is a phase in which the link start point and link end point are registered in the annotation server as Web page annotation using Web annotation technology. The second phase is a phase in which the web page is moved (display switching, jump) based on the link start point and link end point registered as annotations.

  Further, in the first phase, the process for registering the link end point should be executed earlier than the process for registering the link start point. This is because if the link end point is not registered first, the link start point cannot determine which link end point should be designated as the movement destination.

  Note that the second phase can be executed after the link end point registration process and the link start point registration process of the first phase are performed at least once.

  Based on the above matters, the present embodiment will be described.

Data 11 and 21 are acquired. The communication interface program 55 is a TCP / IP stack similar to that of the web browser machine 40.

<First phase (link creation process)>
(Link end point registration process)
First, in the finding management machine 50, when a predetermined operation for starting the link end point registration program 51 is performed through the input device 50b or the network N, the link end point registration program 51 is started and the link end point registration process is started. The

  After starting the link end point registration process, as shown in the flowcharts of FIG. 12 and FIG. 13, the CPU 50d accepts from the operator the input of the URL of the web page for which the headword should be searched in the first step S101. Specifically, the CPU 50d displays an input screen (not shown) on the display device 50a, waits until a predetermined determination operation is performed, and when the predetermined determination operation is performed, the input screen is input at that time. Is acquired as the URL input by the operator.

  Note that the reception process in step S101 may be performed by the operator operating, for example, a web browser machine connected to a network without directly operating the finding management machine 50. In that case, the web browser machine may store an applet that realizes such an operation function, and the finding management machine 50 stores a servlet or CGI that realizes such an operation function. Also good.

  In addition, the reception process of step S101 may be a process of automatically receiving a plurality of URLs recorded in a predetermined table from a predetermined program (not shown) in the finding management machine 50.

  In the next step S102, the CPU 50d stores all URLs accepted in step S101 in a work table (not shown). Thereafter, the CPU 50d executes a first processing loop L1.

  In the first processing loop L1, every time one URL is read from a work table (not shown), the CPU 50d executes the process consisting of steps S103 to S111 for the read URL.

  In step S103, the CPU 50d acquires web page data specified by the processing target URL. Specifically, the CPU 50d transmits an HTTP request message designating a processing target URL through the HTTP client (program) 54, and acquires an HTTP response including web page data in the body from the web server machines 10 and 20 through the HTTP client 54. To do. Thereafter, the CPU 50d advances the process to step S104.

  The CPU 50d that executes these steps S101 to S103 corresponds to the first data acquisition unit and the first data acquisition unit described above. These steps S101 to S103 correspond to the first data acquisition procedure.

  In step S104, the CPU 50d searches the unexamined portion of the web page data acquired in step S103 for words to be used as headwords in order from the top. In addition, as a method of detecting a phrase to be used as a headword, for example, “http://ci.nii.ac.jp/naid/” or “http://www.ntt.co.jp/news/news05/ 0502 / 050210.html ”may be applied. Further, if the web page data to be processed is web page data of a dictionary site, these elements are applied focusing on the b element that makes the character bold and the h1 to h6 elements that make the character a headline. For example, focusing on a pattern having a class definition “class =“ heading ””, a phrase sandwiched between tags that match the pattern may be detected.

  The CPU 50d that executes step S104 corresponds to the above-described search means and search unit. This step S104 corresponds to a search procedure.

  In the next step S105, the CPU 50d determines whether or not a word / phrase to be found as a headword has been detected as a result of the search in step S104. If the word / phrase to be found is detected, the CPU 50d branches the process from step S105 to step S106.

  In step S106, the CPU 50d acquires the position information of the phrase detected in step S105. Note that, after acquiring the web page data in step S103, a parser (not shown) has analyzed the tree structure of the web page data, and the CPU 50d makes an inquiry to the parser (not shown) to detect position information of the detected phrase. To get.

  In the next step S107, the CPU 50d generates fragment designation information that functions as information that defines the link end point, and stores the fragment designation information in the memory unit 50e as content information that identifies the content of the annotation. The content information generated here includes the same phrase as the phrase detected in step S105 as the fragment identifier. The fragment designation information may be a start tag (<a name="">) of the a element having a name attribute, or an id attribute (id = "") embedded in the start tag of any element It may be. In any case, the detected word / phrase is included in the fragment designation information as a fragment identifier.

  In the next step S108, the CPU 50d generates type information specifying that the annotation related to the phrase detected in step S105 functions as the end point of the link, and stores it in the memory unit 50e.

  In the next step S109, the CPU 50d generates annotation data including the processing target URL, the position information acquired in step S106, the content information stored in step S107, and the type information stored in step S108.

  In the next step S110, the CPU 50d transmits the annotation data generated in step S109 to the annotation server machine 30 as data to be registered. When the annotation server machine 30 receives this annotation data, the registration module 31b stores it in the annotation data management table 31a.

  The CPU 50d that executes these steps S105 to S110 corresponds to the first generation unit and the first generation unit described above. Also, these steps S105 to S110 correspond to the first generation procedure.

  In the next step S111, the CPU 50d registers, in the found word management table 53, a record including the words that should be found as head words detected in step S105, the URL to be processed, and the words that are fragment identifiers in step S107. To do. Thereafter, the CPU 50d returns the process to step S104.

  On the other hand, in step S104, when the end of the data is reached without detecting any word / phrase to be found from the web page data acquired in step S103, the CPU 50d can no longer search. The process of the process target URL in the process loop L1 is terminated.

  When the CPU 50d finishes executing the processing including steps S103 to S111 for all URLs in the work table (not shown), the CPU 50d leaves the first processing loop L1 and performs the link end point registration processing according to FIGS. 12 and 13. finish.

  Therefore, according to this link end point registration process, the URL of the web page data of the dictionary site, for example, is simply input by the user of the finding management machine 50, and the location is identified from the web page data specified by the URL. A word / phrase to be output is automatically detected, and an annotation that automatically functions as a link end point is associated with a certain part of the word / phrase.

(Link origin registration process)
Next, in the finding management machine 50, when a predetermined operation for starting the link start point registration program 52 is performed through the input device 50b or the network N, the link start point registration program 52 is started and the link start point registration process is started. Is done.

  After starting the link origin registration process, as shown in the flowcharts of FIGS. 14 and 15, the CPU 50 d receives an arbitrary URL input from the operator in the first step S <b> 201. The specific processing content related to this reception processing is the same as in step S101.

  In the next step S202, the CPU 50d stores all URLs accepted in step S201 in a work table (not shown).

  In the next step S <b> 203, the CPU 50 d reads all headwords from the headword management table 53. Thereafter, the CPU 50d executes a second processing loop L2.

  In the second processing loop L2, every time one URL is read from a work table (not shown), the CPU 50d executes the process consisting of steps S204 to S212 for the read URL.

  In step S204, the CPU 50d acquires web page data specified by the processing target URL. The specific processing content related to this acquisition processing is the same as in step S103.

  The CPU 50d that executes these steps S201, S202, and S204 corresponds to the above-described second data acquisition unit and second data acquisition unit. These steps S201, S202, and S204 correspond to the second data acquisition procedure.

  In the next step S205, the CPU 50d searches the web page data acquired in step S204 for a phrase that matches any headword in the headword management table 53 read in step S203 in order from the top.

  The CPU 50d that executes step S205 corresponds to the above-described search means and search unit. This step S205 corresponds to a search procedure.

  In the next step S206, the CPU 50d determines whether or not a word / phrase that matches any headword in the headword management table 53 has been detected as a result of the search in step S205. If a phrase that matches any headword is detected, the CPU 50d branches the process from step S206 to step S207.

  In step S207, the CPU 50d acquires the position information of the phrase detected in step S206. Note that, after acquiring the web page data in step S204, a parser (not shown) has analyzed the tree structure of the web page data, and the CPU 50d makes an inquiry to the parser (not shown) to detect position information of the detected phrase. To get.

  In the next step S208, the CPU 50d reads from the headword management table 53 a record including the word / phrase detected in step S206 in the “word headword” field.

  In the next step S209, the CPU 50d adds a character “#” to the head of the fragment identifier in the record read in step S208, and further adds it to the end of the URL in the same record. Thereafter, the CPU 50d generates a link tag including a URL with a fragment identifier added at the end as link destination information, and stores the link tag in the memory unit 50e as content information for specifying the content of the annotation.

  In the next step S210, the CPU 50d generates type information that specifies that the annotation related to the phrase detected in step S206 functions as a link starting point, and stores it in the memory unit 50e.

  In the next step S211, the CPU 50d generates annotation data including the processing target URL, the position information acquired in step S207, the content information stored in step S209, and the type information stored in step S210.

  In the next step S212, the CPU 50d transmits the annotation data generated in step S211 to the annotation server machine 30 as data to be registered. When the annotation server machine 30 receives this annotation data, the registration module 31b stores it in the annotation data management table 31a. Thereafter, the CPU 50d returns the process to step S205.

  The CPU 50d that executes these steps S206 to S212 corresponds to the second generation unit and the second generation unit described above. These steps S206 to S212 correspond to the second generation procedure.

  On the other hand, when the end of the data is reached in step S205 without detecting any word / phrase that matches any headword in the headword management table 53 from the web page data acquired in step S204, the CPU 50d Since the search can no longer be performed, the processing of the URL to be processed in the second processing loop L2 is terminated.

  When the CPU 50d finishes executing the processing including steps S204 to S212 for all URLs in the work table (not shown), the CPU 50d leaves the second processing loop L2 and performs the link start point registration processing according to FIGS. 14 and 15. finish.

  Therefore, according to this link start point registration process, the user of the finding management machine 50 simply inputs the URL of arbitrary web page data, and finds the headword from the web page data whose location is specified by the URL. A phrase that matches any headword in the management table 53 is automatically detected, and an annotation that automatically functions as a link starting point is associated with a location of the phrase.

<Second phase (annotation display processing)>
Next, when a predetermined operation for activating the web browser software 41 is performed through the input device 40b in the web browser machine 40, the web browser software 41 is activated. Thereafter, when a predetermined access instruction operation designating an arbitrary URL is performed through the input device 40b, the web browser software 41 transmits an HTTP request message designating the URL through the HTTP client (program) 42, and the web page An HTTP response including data in the body is acquired from the web server machines 10 and 20 through the HTTP client 42.

  When the web browser software 41 acquires web page data in this way, the annotation display module 41c is activated and annotation display processing is started.

  After the start of the annotation display process, as shown in the flowchart of FIG. 16, in the first step S301, the CPU 40d specifies the URL specified at the time of access instruction from the web browser (software) 41 and the location by the URL. Web page data to be received.

  In the next step S302, the CPU 40d inquires of the annotation server machine 30 about the URL received in step S301. When the annotation server machine 30 receives the inquiry request, the annotation server machine 30 activates the transmission module 31c. The transmission module 31c searches the annotation data management table 31a using the URL as a search condition, and determines whether annotation data has been detected. When the annotation data cannot be detected, the transmission module 31c returns an empty response not including the annotation data to the annotation display module 41c. On the other hand, when the annotation data can be detected, the transmission module 31c returns a response including the annotation data to the annotation display module 41c.

  In the next step S303, the CPU 40d stands by until there is a response from the transmission module 31c of the annotation server machine 30. Then, when there is a response from the transmission module 31c, the CPU 40d advances the process from step S303 to step S304.

  In step S304, the CPU 40d determines whether annotation data is included in the response received in step S303. If the annotation data is not included in the response received in step S303, the CPU 40d branches the process from step S304 to step S308. On the other hand, when annotation data is included in the response received in step S303, the CPU 40d executes a third processing loop L3.

  In the third processing loop L3, every time the annotation data included in the response received in step S303 is specified as a processing target one by one, the CPU 40d performs the processing including steps S305 to S307 for the specified annotation data. ,Execute.

  In step S305, the CPU 40d determines whether the type information included in the processing target annotation data indicates “link end point” or “link start point”. If the type information included in the processing target annotation data indicates “link end point”, the CPU 40d advances the process from step S305 to step S306.

  In step S306, the CPU 40d identifies the annotation embedding position in the web page data received in step S301 based on the position information included in the processing target annotation data, and then uses the content information included in the processing target annotation data. The specified fragment designation information is embedded in the position in a predetermined form. If the fragment designation information is a start tag (<a name="">) of an a element having a name attribute, the predetermined form is a form in which the fragment designation information is incorporated into the web page data as an inline element. Say. Further, if the fragment designation information is an id attribute (id = "") embedded in a tag of any element, the predetermined form means a form incorporated in the start tag of any element. After incorporating the fragment designation information into the web page data, the CPU 40d ends the processing of the processing target annotation data in the third processing loop L3.

  On the other hand, if the type information included in the processing target annotation data indicates “link starting point” in step S305, the CPU 40d branches the process from step S305 to step S307.

  In step S307, the CPU 40d identifies the annotation embedding position in the web page data received in step S301 based on the position information included in the processing target annotation data, and then uses the content information included in the processing target annotation data. The specified link tag is embedded at the position. Note that the URL in the link tag includes a fragment identifier. After incorporating the link tag into the web page data, the CPU 40d ends the processing of the processing target annotation data in the third processing loop L3.

  When the CPU 40d finishes executing the processing including steps S305 to S307 for all the annotation data included in the response received in step S303, the CPU 40d leaves the third processing loop L3 and proceeds to step S308.

  In step S308, the CPU 40d designates the web page data annotated in step S306 or S307 or the web page data as received in step S301, and instructs the parser 41a to start processing. Upon receipt of this instruction, the parser 41a separates the tags from the web page data, analyzes the sentence structure based on the tags, and converts the web page data into a form that can be used by the renderer 41b. Then, it is handed over to the renderer 41b. The renderer 41b renders a web page based on the web page data received from the parser 41a. After instructing the parser 41a to start processing, the CPU 40d ends the annotation display processing according to FIG.

  Therefore, according to this annotation display processing, when the web browser (the CPU 40b executing the software 41) acquires the web page data 11, 21 from the web server machine 10, 20, the web page data 11, 21 is related to the URL. If the annotation data to be acquired is acquired from the annotation server machine 30 and the type information in the annotation data indicates “link end point”, the fragment designation information is embedded in the web page data 11 and the type information in the annotation data is “ If it indicates “link start point”, the link tag is embedded in the web page data 21.

<Operational effects of this embodiment>
When the link end point registration program 51 is activated in the finding management machine 50 and the URL “http: //dict/a.html” of the web page data 11 illustrated in FIG. 4 is input (step S101), the finding is performed. A phrase to be a word is detected (steps S102 to S104). For example, if it is specified that a phrase to which the h4 element is applied is detected, “abandon”, “Abstract”, “abstract ideas”, “abuse of discretion” are obtained from the web page data 11 of FIG. ,... Are detected as words to be found as headwords (step S105). Thereafter, position information of each word is acquired (step S106), fragment instruction information (for example, <a name="abandon">) is generated as content information (step S107), and type information indicating "link end point" is generated. The information is generated (step S108), and the information is registered together with the URL as annotation data in the annotation server machine 30 (steps S109 and S110). Each word is registered in the headword management table 53 together with the URL and the fragment identifier (step S111). FIG. 11 shows a state where the above-exemplified words / phrases are registered as headwords. FIG. 8 shows a state in which annotation data relating to these phrases is registered.

  Further, when the link starting point registration program 52 is started in the finding management machine 50 and the URL “http: //xxx/yyy.html” of the web page data 21 illustrated in FIG. 6 is input (step S201). A phrase that matches the headword in the headword management table 53 is detected (steps S202 to S205). For example, since the phrase “abandon” registered in the headword management table 53 in FIG. 11 is included in the web page data 21 in FIG. 6, the “abandon” is obtained from the web page data 21 in FIG. 6. Will be detected. Thereafter, position information of each word / phrase is acquired (step S207), a record corresponding to each word / phrase is read from the headword management table 53 (step S208), and a link tag (<a href = "http: //dict/a.html#abandon ">) is generated (step S209), type information indicating" link starting point "is generated (step S210), and the information is registered in the annotation server machine 30 as annotation data together with the URL. (Steps S211 and S212). FIG. 8 also shows a state in which annotation data relating to the phrase “abandon” is registered.

  In the finding management machine 50, after the work as described above is performed in advance, the user of the web browser machine 40 starts the web browser software 41, and the web page data illustrated in FIG. 21 URL “http: //xxx/yyy.html” is accessed. Then, the web browser (the CPU 40b executing the software 41) acquires the web page data 21 of FIG. 6 from the second web server machine 20, and activates the annotation display module 41c of FIG. The annotation display module 41c acquires annotation data corresponding to the URL from the annotation server machine 30 (steps S301 to S304), determines that the type information indicates “link starting point” (step S305; link starting point), and links A tag (<a href="http://dict/a.html#abandon">) is embedded in the web page data 21 (step S307). FIG. 17 shows the web page data 21 in a state where the link tag is embedded. The web browser 41 uses the parser 41a and the renderer 41b to display a web page based on the web page data 21 in which the link tag is embedded (step S308). FIG. 18 shows a web page displayed based on the web page data 21. In the web page of FIG. 18, the word “abandon” shown in bold is operated as a link button by the link tag.

  Subsequently, when the user of the web browser machine 40 clicks the phrase “abandon” in the web page of FIG. 18, the web browser 41 displays a link tag (<a href = "http: //dict/a.html# Based on the URL in abandon ">), the web page data 11 illustrated in FIG. 4 is acquired from the first web server machine 10, and the annotation display module 41c in FIG. 16 is activated. The annotation display module 41c acquires annotation data corresponding to the URL from the annotation server machine 30 (steps S301 to S304), determines that the type information indicates “link end point” (step S305; link end point), and fragments Designated information (<a name="abandon">, <a name="Abstract">, ...) is embedded in the web page data 11 (step S306). FIG. 19 shows the web page data 11 in a state where each piece of fragment designation information is embedded. The web browser 41 uses the parser 41a and the renderer 41b to display a web page based on the web page data 11 in which the fragment designation information is embedded (step S308). At this time, the web browser 41 displays the web page based on the fragment identifier added to the URL in the link tag so that the fragment specified by <a name="abandon"> is first. . However, a fragment identifier or a tag designating a fragment is not displayed on the web page. FIG. 20 shows a web page displayed with the fragment at the top.

  As described above, according to the computer network system of the present embodiment, when a link button (link starting point) to an explanation page of a phrase is created as a web annotation for the phrase in the web page (FIG. 18), the link Even when the user jumps to the explanation page through the button, it is not necessary to search for a part where the meaning of the word is explained as shown in FIG.

In the embodiment described above, the link start point registration program 52 and the annotation display module 41c operate on different machines, but the link start point registration program 52 and the annotation display module 41c are the same. It may operate on the web browser machine 40. In this case, the link origin registration program 52 (following CPU 40d) does not perform the process of generating the annotation data (steps S210 to S212), but finds it from the web page data 11 and 21 acquired by the web browser 41. After any word / phrase in the word management table 53 is detected, a process of immediately embedding the link tag at a location where the detected word / phrase is present is performed.
