Description

  The present invention relates to an information acquisition technique for acquiring display information of a Web page viewed by a user.

  As is well known, a PC (personal computer) user refers to data such as documents, images, videos, and music on a PC every day. In the process, it is assumed that the user refers to data that has been referred to in the past. Is done. However, as the reference history becomes enormous, it is often difficult to search for past reference data. For example, “Internet Explorer” (registered trademark) can display a list of history data in chronological order, but only character data is displayed, and data cannot be found efficiently.

  Therefore, a system for saving an operation history on a PC including a Web browsing history has been proposed, such as the information recall support tool of Non-Patent Document 1. According to this system, when a Web page is browsed, the viewing date and URL are recorded. As a method for recording a browsing history of a Web page including a frame page, a history recording method disclosed in Patent Document 1 is known. In Patent Document 1, the history of the display state of the frame page of the WWW browser is specified by the HTTP request history in the proxy key server.

  As shown in FIG. 1, a Web page often includes pages divided into frames. Here, “top.html” represents the entire Web page, and the inside of the Web page is divided into two “frame1.html” and “frame2.html”. Furthermore, it is shown that the inside of “frame2.html” is divided into “frame21.html” and “frame22.html”.

  In the case of such a Web page, an html file is read as shown in FIG. At this time, the WWW browser issues an event at the timing when the display of the entire Web page is completed (event 1) and when the display of each frame is completed (event 2).

  Also, when the contents of child frames (divided frames) transition, for example, the contents of “frame21.html” are changed to “frame211.html”, the contents of “frame22.html” are changed to “frame221.html”, and “frame2.html”. ”Transitions to“ frame21.html ”, the file is read and an event occurs as shown in FIG.

  However, in the non-patent document 1, since the browsing of the Web page is recorded by an event corresponding to the event 1, the transition of the page is recorded when the transition of only the child frame occurs as in the event 2 of FIG. I can't. If the event to be used is replaced with one corresponding to event 2, when browsing one web page “top.html”, it is recorded that five web pages have been browsed, and the transition of child frames However, there is a possibility that another problem that a plurality of Web pages are recorded as though one Web page is browsed may occur.

  In Patent Document 1, the Proxy server analyzes the content of an html file and, if it is a frame page, generates a virtual URL including the URL of the child frame. That is, in FIG. 1, the contents of the “html.html” are followed in order from the contents of the html file, a virtual URL is created that summarizes access to the five html files, and the fact that one web page is being viewed is recorded. . However, Patent Document 1 does not describe a method for recognizing and recording a change in display of a part of a frame page when a transition of only a child frame occurs as shown in FIG.

  The present invention has been made to solve the above-described problems of the prior art. When a Web page divided into frames is displayed, the display table information is correctly displayed even if only a child frame has a transition. It is a problem to acquire.

  Therefore, the present invention determines whether a parent frame or a child frame is detected when the reading of the parent frame and the child frame is mixed, and determines whether the child frame is an independent transition or a single group of transitions. To do.

  In one aspect of the Web frame page information acquisition method according to the present invention, the acquisition unit detects a display completion event of the Web browser when the display of the content of the Web page is completed, and a detection event URL included in the event information An acquisition step of acquiring the display URL recognized as being displayed on the Web browser and the display content displayed on the Web browser, and the parent frame determination means detects the display URL acquired in the acquisition step. As a result of comparison with the event URL, if the two URLs match, it is determined that the parent frame is displayed, the display URL is recorded in the table as the received parent frame URL, and is recorded as the parent frame in the event item of the table. A parent frame determination step and a child frame transition determination means If the display URL acquired in the acquisition step matches the received parent frame URL recorded in the table, it is determined that the parent frame has been received and only the child frame has transitioned, and Child frame transition determination step for recording the event frame as a parent frame received child frame, the display content storage instruction means monitors the recorded content of the table, and the time point when the parent frame is recorded in the event item, and an arbitrary period The display content of the Web browser acquired in the acquisition step is stored as the browser browsing history with respect to the acquisition means at the time when the last event is recorded in the group of child frames that have been received in the parent frame. A display content storage instruction step for instructing

  One aspect of the Web frame page information acquisition system according to the present invention detects a Web browser display completion event when the display of the contents of a Web page is completed, a detection event URL included in the event information, and a Web browser The acquisition unit that acquires the display URL recognized as being displayed and the content displayed by the Web browser, the display URL acquired by the acquisition unit and the detection event URL are compared, and the two URLs are If they match, it is determined that the parent frame has been displayed, and the display URL is recorded in the table as a received parent frame URL, and recorded as a parent frame in the event item of the table; When the means does not determine the parent frame, the display URL acquired by the acquisition means and the previous If the received parent frame URL recorded in the table matches, it is determined that the parent frame has been received and only the child frame has transitioned, and a child frame transition determining unit that records the parent frame as a received child frame in the event item; The recorded contents of the table are monitored, and when the parent frame is recorded in the event item and when the last event is recorded in the group of the received child frames of the parent frame continuous within an arbitrary period. Display content storage instruction means for instructing the acquisition means to store the acquired display content of the Web browser as a browser browsing history.

  In addition, this invention is good also as an aspect of the web frame page information acquisition program for functioning a computer as a web frame page information acquisition system. This program can be provided through a network or stored in a recording medium.

  According to the present invention, even if the transition is only a child frame, the transition can be detected and the Web page display content can be saved. Further, it is prevented that it is determined that one Web page is displayed every time a child frame is read.

The figure which shows the example 1 of an event which generate | occur | produces at the time of frame browsing. The figure which shows the example 2 of an event. 1 is a configuration diagram of a Web frame page acquisition system according to a first embodiment of the present invention. The flowchart which shows operation | movement of a parent frame determination means and a child frame determination means. The recording data figure of the same event table. The same event type setting diagram. The block diagram of the Web frame page acquisition system which concerns on 2nd Embodiment of this invention. The same event type setting diagram.

  Hereinafter, a Web frame page information acquisition system according to an embodiment of the present invention will be described. This information acquisition system solves the following problems related to HTML log recording (browser browsing history) with frame division. That is, the top HTML log recording does not record child frame updates, and the child frame recording cannot be distinguished from the case of viewing individual HTML.

  Therefore, the information acquisition system executes (1) a processing step for discriminating whether the frame is a parent (top) frame or a child frame, and (2) in the case of a child frame, whether the operation of one individual child frame is performed according to a time interval. Or processing steps for distinguishing whether continuous frames are received.

<< First Embodiment >>
(1) Configuration Example The information acquisition system according to the first embodiment of the present invention will be described based on FIG. Here, the information acquisition system 1 is implemented as an extended function of the Web browser 2 in a mobile terminal such as a PC (personal computer) or a mobile phone.

  Specifically, the information acquisition system includes display completion event acquisition means 3, display URL acquisition means 4, display content acquisition means 5, parent frame determination means 6, child frame transition determination means 7, event table 8, display content storage. This is realized by the instruction means 9 and the browser browsing history storage unit 10. The event table 8 and the browser browsing history storage unit 10 are provided in storage means such as a hard disk drive device.

  The display completion event acquisition unit 3 detects a display completion event issued by the Web browser 2 when the display of the contents of the Web page is completed, and acquires a detection event URL included in the event information. The display URL acquisition unit 4 acquires the display URL recognized by the Web browser 2 from the Web browser 2 when the display completion event acquisition unit 3 issues an event. The display content acquisition unit 5 acquires the display content from the Web browser 2 when the display completion event acquisition unit 3 issues an event.

  The parent frame determination means 6 determines whether the html file read by the Web browser 2 is a parent frame or a child frame. Here, as a result of comparing the display URL acquired by the display URL acquisition unit 4 with the detection event URL acquired by the display completion event acquisition unit 3, it is determined that the parent frame page is displayed if they match. The display URL is recorded in the event table 8 as the received parent frame URL. At this time, the type of “parent frame” is also recorded in the event table 8.

  The child frame transition determination means 7 determines whether successive child frame readings are independent transitions or a group of transitions by one trigger based on the generation time interval. Here, if the parent frame determination means 6 does not determine the parent frame, and the display URL and the received parent frame URL match, it is determined that the parent frame has been received and only the child frame has transitioned, and the event table 8 Record the type of “parent frame received child frame”. On the other hand, if the display URL does not match the received parent frame URL, the type of “parent frame not received child frame” is recorded.

  The display content saving instruction means 9 monitors the contents of the event table 8 and (1) when the type of “parent frame” is recorded, and (2) the recorded event of the received child frame of the parent frame within one continuous period. Are grouped, and when the last event type of the group is recorded, the display content acquisition means 5 is instructed to store the acquired content in the storage unit 10 as a browser browsing history.

  Therefore, according to the information acquisition system 1, the display content of the Web browser 2 is stored in the storage unit 10 as a browser browsing history at the time of transition of a parent frame and at the time of continuous child frame transition by one opportunity.

(2) Processing Operation Example Hereinafter, a specific processing operation example of the information acquisition system 1 will be described. First, when the user browses a web page with the web browser, when the web browser 2 finishes displaying the contents of the web page, the web browser 2 generates a display completion event.

  At this time, the display completion event acquisition unit 3 detects the display completion event of the Web browser 2 and simultaneously acquires the detection event URL included in the event (display completion event acquisition step). After this acquisition, the display completion event acquisition unit 3 transmits the detection of the display completion event to the display URL acquisition unit 4, and transmits the detection event URL to the parent frame determination unit 6 and the display content acquisition unit 5.

  When the detection of the display completion event is transmitted from the display completion event acquisition unit 3, the display URL acquisition unit 4 acquires the URL recognized by the browser 2 as being displayed, that is, the display URL from the Web browser 2. (Display URL acquisition step). The display URL acquired here corresponds to the URL displayed on the toolbar of the Web browser 2. This display URL is transmitted to the parent frame determination means 6 and the child frame transition determination means 7.

  When the detection of the display completion event is transmitted from the display completion event acquisition unit 3, the display content acquisition unit 5 displays the display content of the browser 2 from the Web browser 2, that is, an html file, an image file included in the file, etc. Is acquired (display content acquisition step).

  Next, the parent frame determination means 6 and the child frame transition determination means 7 start the processing operation after each acquisition step. That is, the parent frame determination unit 6 compares the detected event URL transmitted from the both units 3.4 and the display URL, and performs parent frame determination (parent frame determination step). Here, when the parent frame is displayed as in the case where “top.html” in FIG. 2 is displayed, both the URLs coincide with each other as “top.html”. On the other hand, if a child frame is displayed as when “frame1.html” is displayed, the display URL is “top.html”, the detection event URL is “frame1.html”, and the URLs do not match.

  If the processing steps are described with reference to FIG. 5, the parent frame determination means 6 confirms whether or not the detected event URL matches the display URL (S01). As a result of the confirmation, if the two URLs match, it is determined as a parent frame, and the display URL (same as the detected URL) is recorded in the event table 8 as the received parent frame URL (S02). After this recording, the event type is recorded as “parent frame” in the event table 8 together with the date and time and the detected event URL (S03). FIG. 6 shows a recording example of the event table 8, and the event of the parent frame display of “top.html” is recorded as “eventID = 1”. In addition, as shown in FIG. 7, it is preferable to set a code number in advance and record the code number in the event type of the event table 8.

  On the other hand, if it is not determined to be the parent frame, that is, if the match between the display URL and the detected event cannot be confirmed in S01, the process proceeds to the processing step of the child frame transition determination means 7. In this processing step, the display URL transmitted from the display URL acquisition means is compared with the received parent frame URL recorded in the event table 8, and it is confirmed whether or not the two URLs match (S04).

  As a result of confirmation, if the two URLs match, it is determined as a “parent frame received child frame”, whereas if they do not match, it is determined as a “parent frame unreceived child frame” and the determination result is recorded in the event table 8. (S05.S06). As shown in FIG. 6, the determination result is recorded for each event ID as date / time, detection event URL, and event type. Here, in the event table 8, “eventID = 2, 3, 4” is recorded as the parent frame received child frame, “eventID = 1, 5” is recorded as the parent frame, and “eventID” is recorded as the parent frame unreceived child frame. = 6 "is recorded.

  The recorded content of the event table 8 is monitored by the display content saving instruction means 9 and is displayed when the parent frame is displayed, that is, when “eventID = 1, 5” occurs (when the event type is recorded in the event table 8). The display content acquisition means 5 is instructed to save the display state of the Web browser 2 in the storage unit 10 as the browser browsing history (display content storage instruction step).

On the other hand, at the time of displaying the child frame that has received the parent frame, that is, at the place where recording such as “eventID = 2, 3, 4” is performed,
(A) One independent child frame transition was repeated three times.
(B) Three child frame readings occurred consecutively triggered by one click, etc.
There are two possible patterns.

  Here, in the case of the pattern (A), the Web display contents should be saved when “eventID = 2, 3, 4” occurs. On the other hand, in the case of the pattern (B), the Web display content should be saved when “eventID = 4” occurs. For both patterns, the difference is that the event occurrence interval is long in the case of the pattern (A) and the event occurrence interval is short in the case of the pattern (B).

Therefore, if a process (grouping) in which a threshold T related to time is set and events occurring at time intervals equal to or less than the threshold T are grouped into later events (grouping) is performed in the display content saving instruction step, both patterns are appropriate. Can be processed. Specifically, as shown in FIG. 6, the "eventID = 2" and t ₁ the distance between the "eventID = 3", "eventID = 3" and "eventID = 4" t ₂ the distance between, t _{If 1} <T, t ₂ <T, then
-EventID = 2 is integrated into 3.
-EventID = 3 is integrated into 4.
It will be.

  If events are integrated (grouped) in this way, a storage instruction is sent to the display content storage means 5 when a child frame that has received a parent frame (when an event type is recorded in the event table 8) is generated, whereby “eventID” When “= 4” occurs, the display content of the Web page is stored in the storage unit 10 as a browser history, and the display content of the appropriate Web page is stored.

  That is, according to the information acquisition system 1, when the reading of the parent frame and the child frame is detected in a mixed manner, not only the determination of the parent frame or the child frame but also the transition of the child frame independently or one trigger is generated. It is appropriately determined whether or not it is a group transition, and a storage instruction is sent to the display content storage means 5.

  Therefore, in the case of a transition of only a child frame, the transition is properly detected without being determined to display one Web page every time the child frame is read, and the display content of the correct Web page is saved as the browser history. .

<< Second Embodiment >>
The information acquisition system according to the second embodiment of the present invention will be described with reference to FIG. Here, a click link acquisition unit 11, a click link URL storage unit 12, and a click child frame determination unit 13 are added to the configuration example of the information acquisition system 1.

The click link acquisition unit 11 records the clicked link in the storage unit 12 as the click link URL each time the link is clicked (click link acquisition step). Here, the click link URL recorded in the storage unit 12 is replaced with the generation time interval t ₁ . When used in place of t _2,
If the link to “frame 211.html”, “frame 221. html”, “frame 21. html” is clicked, that is, if the link exists in the click link URL, “eventID = 2, 3, 4” "Indicates that the transition of the independent child frame is repeated three times. Therefore, the Web display content should be saved when each of “eventID = 2, 3, 4” occurs.
・ If only the link to “frame21.html” is clicked, “eventID = 2, 3” is generated with “eventID = 4” as the trigger, so the content displayed on the Web when “eventID = 4” occurs Should be saved.
That is true.

  Accordingly, first, as shown in FIG. 9, a click child frame “4” is added to the event type of FIG. Next, when the child frame transition determination unit 7 determines that the click child frame determination unit 13 determines that the child frame has been received as a parent frame, the click child frame determination unit 13 refers to the storage unit 12 and the detected event URL exists in the click link URL. Search whether or not. If it exists as a result of the search, it is recorded as a click child frame in the event table 4 using the newly added event type “4” (click child frame determination step).

  Therefore, according to the information acquisition system 1 of the second embodiment, the display content storage instructing unit 9 records the time point when the parent frame is recorded in the event table 8 and the event type of the click child frame in the event table 8. By sending a storage instruction to the display content acquisition means 5 at the time (display content storage instruction step), the display content of an appropriate Web page is stored as a browser history in the storage unit 10 as in the first embodiment.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation is possible for the system configuration etc. within the range described in each claim. For example, each of the acquisition units 4 to 6 is not necessarily configured differently. One acquisition unit detects a display completion event of the Web browser, and the detected event URL included in the event information and the Web browser display The display URL recognized as being displayed and the display content displayed by the Web browser may be acquired.

≪Programs≫
The present invention can also be configured as a program that causes a computer to function as some or all of the means 1 to 13 of the information acquisition system. According to this program, all or part of the steps are executed by a computer.

  This program can be provided through a network such as a website or e-mail. The program is recorded on a recording medium such as a CD-ROM, DVD-ROM, CD-R, CD-RW, DVD-R, DVD-RW, MO, HDD, Blu-ray Disk (registered trademark). It is also possible to save and distribute. This recording medium is read using a recording medium driving device, and the program code itself realizes the processing of the above embodiment, so that the recording medium also constitutes the present invention.
