  FIG. 4 is a diagram showing a screen display example of the Web page P acquired from the server device (information site A) 10A [http://www.sight.a.co.jp/] in the information terminal device 20, for example. is there.

  FIG. 5 is a diagram showing an HTML source Phtm describing the link text Ltxt1 portion of the Web page P in FIG.

  As shown in FIG. 4, the Web page P displayed on the display unit 27 of the information terminal device 20 is hypertext, and all of the five individual titles belonging to the main title T “Today's breaking news” are linked text Ltxt1. ~ Ltxt5 is set. Each of the link texts Ltxt1 to Ltxt5 is described in a tag element surrounded by “A” in the HTML source Phtm, part of which is shown in FIG. 5, and is associated with the URL of the link destination Web page. .

  For example, in the Web page P displayed on the display unit 27, when the link text “Order by Prime Minister, Cabinet Support Rate” Ltxt1 corresponding to the first individual title belonging to the main title T is focused, HTML describing the link text Ltxt1 The URL [http://www.sight_b.co.jp/news002.html] of the link destination Web page is acquired from the source Phtm as indicated by being surrounded by a broken line a.

  As described above, the Web browser program of the information terminal device 20 acquires the Web page as the basic function in accordance with the access to the server devices 10A, 10B, 10C,... It has a function of analyzing a tree structure made up of HTML tags and expanding and displaying the screen in the frame buffer FB in the storage unit 23.

  In addition to the function of acquiring and displaying the Web page P from the server device of the Web site requested to access in response to a user operation, the information terminal device 20 performs the URL registration list memory 23a at a certain time T1. A function that automatically accesses the server device of each URL registered in (see FIG. 2) and extracts link texts Ltxt1 to Ltxtm that are individual titles in all Web pages P provided by each server device. A function of acquiring link destination URLs corresponding to the respective link texts Ltxt1 to Ltxtm, a function of accessing each acquired link destination URL and extracting the body text, and an individual ID for each of the registered URLs Corresponding the title (link text), link destination URL, and body text with the body ID associated with the corresponding URL_ID The extraction result list memory 23b has a function of registering in (see FIG. 3) (step SA [Display text acquisition process] in FIG. 6).

  Then, the information terminal device 20 uses the similarity between the URL texts registered in the extraction result list memory 23b and the text texts associated with other URL IDs based on the text text with the smaller URL ID. In order to determine the degree of similarity, the body text whose similarity is determined to be higher than the specified value is associated with the body text having the smaller URL_ID, and a required display mark is added. And has a function of deleting the other body text (step SB [similarity determination processing] in FIG. 6).

  Further, the information terminal device 20 displays an individual title (link text) associated with the required body text when the body text with the required display mark is present in the extraction result list memory 23b. The window 27 has a function of displaying a window (step SC [display processing] in FIG. 6).

  The function of acquiring and displaying important information from each Web site registered in advance is realized by a program that plugs in or adds to the Web browser program, for example.

  Next, the important information acquisition / display function by the information terminal device 20 of the server / client system having the above-described configuration will be described.

  FIG. 6 is a flowchart showing an outline of important information acquisition / display processing by the information terminal device 20.

  In this important information acquisition / display processing, the display target text acquisition processing (step SA), similarity determination processing (step SB), and display processing (step SC) whose outline of the function has been described above are performed for a predetermined period of time. It is repeatedly executed every T1 (step SD, SE → SA).

  By this important information acquisition and display processing, an individual title (link text) of information having high importance among information obtained from each of the information sites A, B, C,. It can be displayed.

  The detailed processing will be described below.

  FIG. 7 is a flowchart showing a display target text acquisition process (SA) accompanying the important information acquisition display process.

  First, the value of the variable x managed in the storage unit 23 is initialized to the number “n” of URLs registered in the URL registration list memory 23a (see FIG. 2), and the variable managed in the storage unit 23 The value of y is initialized to a value “1” that designates the top of the registered n URLs (step A1).

  Then, the server device (for example, information site A) 10A according to the y (= 1) th URL registered in the URL registration list memory 23a is accessed, and the web page P of the information site A is acquired. Then, link texts Ltxt1 to Ltxtm of each individual title described in the Web page P are extracted, and stored in the extraction result list memory 23b (see FIG. 3) in association with the ID (= 1) of the URL. (Step A2).

  In addition, the process which extracts the link text Ltxt1-Ltxtm of each individual title described in the web page P acquired from the said server apparatus is performed as follows, for example.

  First, a tree structure including HTML tags of the Web page P is analyzed, and “columns” in the Web page P are extracted. In addition, from the HTML structural analysis, for example, for each “column”, a “strong” character string that is larger than a surrounding character string and is a conspicuous character font is extracted and listed. Then, link texts Ltxt1 to Ltxtm of each individual title are certified and extracted from the positional relationship, strength, number, etc. of the listed “strong” character strings.

  Normally, for example, top news posted on a news information site often displays individual titles in a large font or bold font. Therefore, it is possible to extract individual titles about important information such as top news by extracting titles by the above processing.

  Then, the variable n managed in the storage unit 23 is the number “m” of individual titles (link texts Ltxt1 to Ltxtm) extracted from the Web page P corresponding to the y-th (= 1) URL in step A2. (Step A3).

  Here, the variable n is not 0 (step A4 (No)), that is, at least one or more individual titles (link text) are extracted from the Web page P corresponding to the y-th (= 1) URL. When it is determined, the Web page LP of each link destination (see FIG. 8) is acquired according to each link destination URL of the extracted n (= m) individual titles (link text). Then, the text text Htxt ... is extracted from each link destination Web page LP ..., and is associated with the link destination URL together with the link source URL_ID and the text ID associated with the link source URL_ID, It is registered in the extraction result list memory 23b (see FIG. 3) (steps A5, A6 → A4).

  The process of extracting the body text Htxt from the linked Web page LP is executed as follows, for example.

  FIG. 8 is a diagram showing a screen display example of the linked Web page LP described by the HTML source Phtm partially shown in FIG.

  The HTML source LPhtm of the link destination Web page LP includes the headline text “Prime Minister, Cabinet” which is the same (or similar) as the link text “Order from Prime Minister and Cabinet Support Rate” Ltxt1 extracted from the link source Web page P. There is a tag element enclosed in “H1” that contains “order to support rate” Mtxt.

  The body text Htxt corresponding to the heading text “Prime Minister, Order with Cabinet Support Rate” Mtxt is a tag element “P” after the tag element “H1” including the heading text “Order with Prime Minister, Cabinet Support Rate” Mtxt. Are described as a relatively long character string having several readings.

  For this reason, in order to extract the body text Htxt corresponding to the link text Ltxt of the individual title extracted from the link source Wb page P from the HTML source LPhtm of the link destination Web page LP, the same (or similar) to the link text Ltxt. The tag element “H1” including the headline text Mtxt) is retrieved, and the text including the set number of punctuation marks and the number of characters greater than the set number is extracted from the tag element “P” thereafter.

  Thus, according to the processing of steps A4 to A6, the body texts Htxt1 to the link destination Web pages LP1 to LPm corresponding to the individual titles (link texts Ltxt1 to Ltxtm) of the Web page P corresponding to the yth (= 1) URL. When Htxtm is extracted and registered in the extraction result list memory 23b in association with each body ID “1-1” to “1-m1” of the corresponding URL_ID “1”, for example, as shown in FIG. The value of the variable y is incremented and set to “2” (step A7), and the processing after step A2 is repeated (step A8 (No) → A2).

  That is, the individual titles (link texts Ltxt1 to Ltxtm) of the Web page P corresponding to the y (= 2) th URL registered in the URL registration list memory 23a are extracted by the processing of the next step A2. Then, by the processing of the next steps A3 to A6, the linked Web pages LP1 to LP1 corresponding to the individual titles (link texts Ltxt1 to Ltxtm) of the Web page P corresponding to the extracted yth (= 2) URL. LPm body texts Htxt1 to Htxtm are extracted, and as shown in FIG. 3, the extracted result list memory is associated with the body IDs “2-1” to “2-m2” of the corresponding URL_ID “2”. 23b.

  Subsequently, while the value of the variable y is sequentially incremented, the processing in steps A2 to A6 is repeated according to all n (= x) URLs registered in the URL registration list memory 23a, and the extraction result list is displayed. After generating (23b), if it is determined that the value of variable y incremented in step A7 exceeds the value of variable x (= n) (step A8 (Yes)), the series of display target texts The acquisition process ends, and the process proceeds to the similarity determination process (SB) in FIG.

  FIG. 9 is a flowchart showing similarity determination processing (SB) accompanying the important information acquisition display processing.

  When the process proceeds to the similarity determination process, first, the values of the variable x and the variable y managed in the storage unit 23 are both initialized to “1” (step B1). The variable x is a value for sequentially counting the body text corresponding to each individual title (link text) for each URL_ID registered in the extraction result list memory 23b, and the variable y is the URL registration list memory 23a. This is a value for sequentially counting the URL_ID registered in.

  Further, the total number of URLs registered in the URL registration list memory 23a (see FIG. 2) is substituted for the value of the variable ymax managed in the storage unit 23 (step B2).

  The text text corresponding to the y (= 1) th URL_ID “1” registered in the extraction result list memory 23b (see FIG. 3) is added to the value of the variable xmax managed in the storage unit 23. Is substituted (step B3).

  Further, the variable y + 1 (= 2) is substituted for the value of the variable m managed in the storage unit 23 (step B4).

  Then, the value of the variable n managed in the storage unit 23 is initialized to “1”, and m (=) registered in the extraction result list memory 23b (see FIG. 3) as the value of the variable nmax. 2) The total number (m2) of body texts corresponding to the second URL_ID “2” is substituted (step B5).

  Then, the x (= 1) th body text corresponding to the y (= 1) th URL_ID “1” registered in the extraction result list memory 23b, and the m (= 2) th URL_ID “2”. The similarity with the n (= 1) -th body text corresponding to "is determined (step B6), and it is determined whether or not the similarity is higher than a preset specified value (threshold value) (step B6). B7).

  If it is determined that the similarity between the two body texts is equal to or less than a specified value (threshold) (step B7 (No)), the body text corresponding to the m (= 2) th URL_ID “2” is selected. The value of the variable n for designating is incremented and set to “2” (step B8).

  Then, it is determined whether or not the variable n (= 2) has exceeded the total number nmax (= m2) of body texts corresponding to the m (= 2) -th URL_ID “2” (step B9) and has not yet exceeded. Is determined (step B9 (No)), the x (= 1) th body text corresponding to the y (= 1) th URL_ID “1” registered in the extraction result list memory 23b, and , The similarity with the n (= 2) -th body text corresponding to the m (= 2) -th URL_ID “2” is obtained (step B6), and the similarity is set to a predetermined value (threshold value). ) Is determined (step B7).

  That is, by repeatedly executing the processing of steps B5 to B9, the x (= 1) th corresponding to the y (= 1) th URL_ID “1” registered in the extraction result list memory 23b. With the body text as a reference, the degree of similarity is sequentially obtained by comparing each body text (n (= 1) to nmax (= m2)) corresponding to the m (= 2) -th URL_ID “2”. In each case, it is determined whether or not the obtained similarity is higher than a specified value (threshold value).

  For example, the x (= 1) -th body text corresponding to the y (= 1) -th URL_ID “1” registered in the extraction result list memory 23 b and the m (= 2) -th URL_ID “ When the similarity with the n (= 2) -th body text corresponding to 2 ″ is obtained (step B6), when it is determined that the similarity is higher than a specified value (threshold) ( Step B7 (Yes)), a display-required mark is added in association with the x (= 1) -th individual title and body text corresponding to the former y (= 1) -th URL_ID “1”, and is displayed as a display target. It is set (step B10).

  Accordingly, the n (= 2) th individual title and body text corresponding to the latter m (= 2) th URL_ID “2” are deleted from the extraction result list memory 23b (step B11).

  Then, the value of the variable m is incremented and set to “3” (step B12), and the variable m (= 3) is the total number ymax of URLs registered in the URL registration list memory 23a (see FIG. 2). Is judged (step B13).

  Here, if it is determined that the variable m still does not exceed ymax (step B13 (No)), the value of the variable n is initialized to “1”, and the extraction result list is set to the value of the variable nmax. The total number (m3) of body texts corresponding to the m (= 3) th URL_ID “3” registered in the memory 23b (see FIG. 3) is substituted (step B5).

  Then, the x (= 1) th body text corresponding to the y (= 1) th URL_ID “1” registered in the extraction result list memory 23 b and the m (= 3) th URL_ID “3”. The similarity with the n (= 1) -th body text corresponding to "is determined (step B6), and it is determined whether or not the similarity is higher than a preset specified value (threshold value) (step B6). B7).

  In other words, this makes the m (= 3) th text based on the x (= 1) th body text corresponding to the y (= 1) th URL_ID “1” registered in the extraction result list memory 23b. Similarities are sequentially obtained for the respective body texts (n (= 1) to nmax (= m3)) corresponding to the URL_ID “3”, and the similarities obtained in the same manner are obtained each time. It is determined whether or not the value is higher than a specified value (threshold value) (steps B6 to B9).

  Thereafter, the processing of steps B5 to B13 is repeated, so that the x (= 1) th corresponding to the y (= 1) th URL_ID “1” registered in the extraction result list memory 23b. Using the body text as a reference, the similarity determination process is repeated with all body texts from URL_ID “2” to URL_ID “n” as comparison targets.

  Each time it is determined that the similarity is higher than the specified value (threshold value) (step B7 (Yes)), it is associated with the xth individual title and body text corresponding to the yth URL_ID on the reference side. The required display mark is added (step B10), and the nth individual title and body text corresponding to the mth URL_ID on the comparison target side are deleted from the extraction result list memory 23b (step B11). At that time, the variable m designating the URL_ID on the comparison target side is incremented (step B12).

  Here, a specific method for obtaining a similarity by comparing two different character strings (body text) will be described.

  As a method of calculating the similarity by comparing two different character strings, the Levenshtein distance (the number of characters that can be added, deleted, or replaced with the same number of characters in the minimum number of times) is calculated. Various methods such as a method and a method for obtaining a Trigram (a ratio of three characters when a character string is shifted one character at a time and how many characters match) have already been considered. Then, these methods are used.

  The threshold for determining whether or not the two character strings (body text) are similar based on the degree of similarity obtained according to the method is a tuning parameter, and it is desired to strengthen the narrowing down of important information. It is adjusted according to the user's preference, such as the reverse.

  Thus, URL_ID “2” to URL_ID “n” based on the x (= 1) -th body text corresponding to the y (= 1) -th URL_ID “1” by repeating the steps B5 to B13. Similarity determination processing is performed with all body texts up to "" as comparison targets, and the value of the variable m incremented in step B12 is registered in the URL registration list memory 23a (see FIG. 2) in step B13. If it is determined that the total number of URLs ymax has been exceeded (step B13 (Yes)), the value of the variable x is incremented and set to "2" (step B14).

  The text of the incremented variable x corresponds to the value of xmax, that is, the y (= 1) th URL_ID “1” registered in the extraction result list memory 23b (see FIG. 3). It is determined whether or not the total number of texts (m1) has been exceeded (step B15).

  Here, when it is determined that the incremented variable x (= 2) does not exceed the value of xmax (step B15 (No)), the process returns to the process from step B4, and the value of the variable m is changed to the value of the variable m. The variable y + 1 (= 2) is substituted again.

  Then, by repeating the processing of steps B5 to B13, the URL_ID “2” to the URL_ID “2” to the URL (ID) corresponding to the y (= 1) th URL_ID “1” is used as a reference. Similarity determination processing in which all body texts up to URL_ID “n” are compared is repeated.

  Further, by repeating the processing of the steps B4 to B15, the value of the variable x for sequentially designating each body text corresponding to the y (= 1) -th URL_ID “1” is incremented. Similarity determination processing in which all body texts from “2” to URL_ID “n” are compared is repeated.

  The value of the variable x incremented in step B14 corresponds to the value of xmax, that is, the y (= 1) th URL_ID “1” registered in the extraction result list memory 23b (see FIG. 3). If it is determined that the total number (m1) of the body text has been exceeded (step B15 (Yes)), the value of the variable y for designating the URL_ID on the reference side of the similarity determination is incremented to “2”. It is set (step B16).

  Then, it is determined whether or not the value of the incremented variable y exceeds the value of ymax, that is, the total number of URLs registered in the URL registration list memory 23a (see FIG. 2) (step B17).

  If it is determined that the incremented variable y (= 2) does not exceed the ymax value (step B17 (No)), the value of the variable x is initialized to “1” (step B17). B18).

  Then, returning to the processing from step B3, the value of the variable xmax corresponds to the y (= 2) th URL_ID “2” registered in the extraction result list memory 23b (see FIG. 3). The total number (m2) of body text is substituted.

  Then, the variable y + 1 (= 3) is substituted for the value of the variable m.

  As a result, the processes in steps B5 to B13 are repeated, so that the x (= 1) th body text corresponding to the y (= 2) th URL_ID “2” is used as a reference, and the URL_ID “3” to Similarity determination processing in which all body texts up to URL_ID “n” are compared is repeated.

  Further, by repeating the processing of the steps B4 to B15, the value of the variable x for sequentially designating each body text corresponding to the y (= 2) th URL_ID “2” is incremented. Similarity determination processing in which all body texts from “3” to URL_ID “n” are compared is repeated.

  Further, by repeating the processes of steps B3 to B18, the value of the variable y for sequentially specifying the URL_ID on the reference side of the similarity determination is incremented, while corresponding to the incremented y-th URL_ID. The similarity determination process is repeated for each body text corresponding to the URL_ID from m (= y + 1) th to ymax, with each body text as a reference.

  Thereafter, when it is determined that the value of the variable y incremented in step B16 exceeds the value of ymax, that is, the total number of URLs registered in the URL registration list memory 23a (see FIG. 2) (step B17). (Yes)), the series of similarity determination processing ends, and the process proceeds to the display processing (SC) in FIG.

  As a result, the degree of similarity between the URL_IDs registered in the extraction result list memory 23b and the body text associated with the other URL_IDs in order is brute in order based on the body text having the smaller URL_ID. Determined. When the similarity is determined, the body text whose similarity is determined to be higher than the specified value (threshold value) is added with a display mark in association with the body text having a smaller URL_ID, and the other text is displayed. The body text is deleted.

  The body text deleted from the extraction result list memory 23b and becoming null has a similarity of 0% regardless of any text (including comparison between null texts).

  For this reason, the similarity between the URL_IDs registered in the extraction result list memory 23b and the body texts associated with other URL_IDs is determined in order based on the body text having the smaller URL_ID. Even if the determination is made, the more the process proceeds, the more the body text that is determined that the similarity is higher than the specified value and one of them is deleted increases, so the load associated with the process gradually decreases.

  FIG. 10 is a flowchart showing a display process (SC) accompanying the important information acquisition display process.

  FIG. 11 is a diagram showing an example of an important information display operation accompanying the display process (SC) of the important information acquisition display process.

  When the display process is started, it is first determined whether or not there is a display target item to which a display-required mark is added in the extraction result list stored in the extraction result list memory 23b (step C1). ).

  Here, when it is determined that there is an item to be displayed with a display required mark added in the extraction result list (23b) (step C1 (Yes)), the display screen data currently drawn in the frame buffer FB is displayed. Cleared (step C2).

  Then, the individual title (link text) stored in the item to which the display required mark is added in the extraction result list (23b) is read (step C3) and rendered as display screen data in the frame buffer FB. (Step C4).

  As a result, for example, as shown in FIG. 11A, the display unit 27 of the information terminal device (mobile phone) 20 has an individual title (link) of the item to which the required display mark is added in the extraction result list (23b). An important information list window W that lists (text) is displayed.

  Then, in this important information list window W, for example, as shown in FIG. 11B, when the focus f is adjusted to the individual title “Prime Minister, Order to Cabinet Support Rate” in accordance with the user operation, the focus f Is read in association with the individual titles that are combined and stored in the extraction result list (23b). It will be displayed.

  The display target text acquisition process (step SA) in FIG. 7, the similarity determination process (step SB) in FIG. 9, and the display process (step SC) in FIG. 10 are performed every predetermined time T <b> 1. It is repeatedly executed (step SD, SE → SA), and is always updated to the latest information.

  Therefore, according to the important information acquisition and display function by the information terminal device 20 of the server client system having the above-described configuration, the URL of each user-desired information site registered in advance in the URL registration list memory 23a is accessed. An individual title (link text) described in the corresponding Web page is extracted. As a result, the link destination URL of each individual title (link text) is accessed, and the body text described in the Web page corresponding to each link destination URL is extracted. Then, the extracted individual title (link text), link destination URL, and body text are stored in the extraction result list memory 23b in association with the ID of each registered URL. Then, the similarity of the body text is obtained between the URL_IDs stored in the extraction result list (23b), and only the individual title corresponding to the body text having the high similarity is displayed in the important information list window W. Displayed on the unit 27. When the focus f is set to the desired individual title displayed in the window, the body text corresponding to the desired individual title is read and displayed as a pop-up window Wp.

  For this reason, it is possible to extract and display only information having a high probability of being important to the user, such as being posted at the same time on a plurality of information sites registered in advance by the user.

  Further, according to the important information acquisition and display function by the information terminal device 20 of the server / client system having the above-described configuration, one of the body texts determined to have a high similarity in the extraction result list memory 23b has a display-required mark. The added display target is set, and the other body text is deleted. For this reason, body text with a high degree of similarity is not set as a display target in duplicate.

  Furthermore, according to the important information acquisition and display function by the information terminal device 20 of the server / client system having the above-described configuration, the individual title (link text) extraction processing from the Web page corresponding to the registered URL, the extracted individual title Extraction processing of body text from the Web page corresponding to the link destination URL, similarity determination processing of the link destination body text corresponding to individual titles between the registered URLs, and body text determined to have high similarity The process of setting the individual title as a display target is repeatedly executed every certain time T1. For this reason, it is possible to always extract and display only information having a high probability of being important to the user in the latest state.
