Description

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

  As is well known, a user of a personal computer (hereinafter referred to as a PC) browses documents, images, videos, music, and other data on the Web every day on the PC. A situation is assumed in which data is viewed again.

  However, as the browsing history becomes enormous, it is often difficult to search for past browsing data. For example, “Internet Explorer (registered trademark)” of Microsoft Corporation can display history data in a list 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. For example, a system disclosed in Patent Document 1 is known as a system for recording browsing of Web pages divided into frames.

JP2011-90384A

  The system of Patent Document 1 mainly uses a Web page divided into frames as shown in FIG. Here, “top.html” represents the entire Web page, and the inside of the Web page is divided into two “frame1.html” and “frame2.html”. Further, the inside of “frame2.html” is divided into two “frame21.html” and “frame22.html”. In Patent Document 1, an upper frame such as “frame2.html” is represented as a parent frame, and a lower frame such as “frame21.html” is represented as a child frame.

  In the case of the Web page, an html file is read as shown in FIG. 2, and the Web browser generates a display completion event as shown in 2-1.2-2.2-3.2-4.2-5. To do. In addition, when only the contents of the lower frame transition, that is, the contents of “frame21.html” transition to “frame211.html”, the contents of “frame22.html” transition to “frame221.html”, and “frame2. When the content of “html” transitions to “frame21.html”, the file is read as shown in FIG. 3 and a display completion event occurs as shown in 3-1.3-2.3-3.

  At this time, the system of Patent Document 1 determines whether the html file read by the Web browser is an upper frame or a lower frame. Here, when the lower frame is read prior to the upper frame as shown in FIG. 2, it is determined that the reading of the lower frame is accompanied by the reading of the upper frame.

  That is, if an upper frame transition event 2-5 is detected, it is determined that the lower frame transitions 2-1 to 2-4 prior to the event 2-5 are associated with the upper frame transition, and only the upper frame transition is recorded. To do. Also, as shown in FIG. 3, when the reading of the lower frame occurs independently, it is determined that the lower frame is a single transition, and the lower frame transition is recorded. Here, the determination of the transition of the lower frame alone is made by the fact that the transition of the upper frame does not occur within a certain time after the occurrence of the transitions 3-1 to 3-3 of the lower frame.

  However, there is a possibility that the display completion event generated by the Web browser is switched in the order of generation as shown in FIG. For example, a display completion event that normally occurs in the order shown in FIG. 2 occurs after the lower frame “frame2.html” is read after the upper frame “top.html” is read, as shown in FIG. Display completion events may occur in the order of 4-2.4-3.4-4.4-5.

  Here, the display completion events 4-1 to 3 in FIG. 4 correspond to the display completion events 2-1 to 2-3 in FIG. 2, the display completion event 4-4 corresponds to the display completion event 2-5, The display completion event 4-5 corresponds to the display completion event 2-4. Therefore, the display completion events occurring in the order of 2.4.2-5 in FIG. 2 are reversed in the order of 2-5 (4-4). It occurs in the order of 2-4 (4-5).

  In this case, since the system of Patent Document 1 determines that the upper frame transition occurs at the time when the display completion event 4-4 occurs, the lower frame “frame2.html” is determined to be another Web page transition, which is excessive. There was a problem that the browsing history of Web page transitions was recorded.

  The present invention has been made to solve the above-described problem of Patent Document 1, and a transition of a Web page occurs when a change in the order of occurrence occurs in a transition of an upper frame and a transition of a lower frame in a Web page. It is a problem to be processed accurately.

  Therefore, the present invention determines whether or not display completion events have occurred continuously, and acquires an event sequence of display completion events. For example, if a display completion event of the Web browser is detected, it is detected whether the Web browser is busy or not, and an event sequence is acquired with the time point when the busy state is canceled as a boundary.

  The event sequence extracted here includes the display completion event of each frame, so even if there is a change in the original generation order of the upper and lower frames, it is possible to correctly handle the change. It becomes.

  A Web page information acquisition system of the present invention detects a display completion event of a Web browser when the display of the contents of a Web page is completed, and displays a display completion event acquisition unit that acquires detection event information included in the event information, When the completion event acquisition means detects a display completion event, display content acquisition means for acquiring the display content of the Web page from the Web browser, and whether or not display completion events have occurred consecutively based on the detected event information acquired by the display completion event acquisition means A continuous display completion event is determined based on the detection event information, and the continuous state setting means for outputting a continuous event state if it is determined that the event has occurred, and the boundary of the continuous event state output by the continuous state setting means. The event sequence acquisition means for acquiring the event sequence and the event sequence acquisition means The transition completion unit that identifies the display completion event that caused the Web page transition based on the event sequence and writes the detected event information of the identified display completion event to the table, and the display completion that the transition determination unit wrote to the table Storage instruction means for instructing the display content acquisition means to save the display content of the Web browser corresponding to the event as a browsing record.

The Web page information acquisition method of the present invention is a display in which a display completion event acquisition unit detects a display completion event of a Web browser when content display of a Web page is completed, and acquires detection event information included in the event information. When the completion event acquisition step, the display content acquisition means detects the display completion event at the display completion event acquisition step, the display content acquisition step of acquiring the display content of the Web page from the Web browser, and the continuous state setting means includes the display completion event Based on the detected event information acquired in the acquisition step, it is determined whether or not a display completion event has occurred continuously. If it is determined that the event has occurred continuously, a continuous state setting step for outputting an event continuous state and an event string acquisition means Detects the boundary of the continuous event status output in the status setting step An event sequence acquisition step for determining an event sequence based on the information and acquiring an event sequence of continuous display completion events, and a display completion event causing the transition of the web page based on the event sequence acquired by the transition determination means in the event sequence acquisition step And a transition determination step of writing the detected event information of the specified display completion event in the table, and the save instruction means displays the display content of the Web browser corresponding to the display completion event written in the table in the transition determination step A storage instruction step for instructing the content acquisition means to store it as a browsing record.

  The present invention can also be configured as a program that causes a computer to function as the system. This program can be provided through a network or a recording medium.

  According to the present invention, even if a change occurs in the order of occurrence between the transition of the upper frame and the transition of the lower frame in the Web page, the transition of the Web page can be accurately processed.

  Hereinafter, a Web page information acquisition system according to an embodiment of the present invention will be described. This information acquisition system mainly processes Web pages divided into frames, and acquires and records the transition progress of the Web pages viewed by a user using a Web browser.

  At this time, even if there is a transition only in the lower frame, display information can be obtained accurately, and even if there is a change in the display completion event generation order at the time of Web page transition, the change can be absorbed and the display information can be acquired. That is, according to the information acquisition system, an event sequence of a series of display completion events satisfying a predetermined requirement is acquired, and the transition timing of the Web page is specified based on the acquired event sequence.

  As a result, even when the display completion event of the highest frame (such as “top.html”) does not occur at the end, the page transition timing can be detected correctly, and the transition history of the web page of the user browsing is accurately recorded. The

≪Configuration example≫
A configuration example of the information acquisition system will be described with reference to FIG. Here, the information acquisition system 1 is implemented as an extended function of the Web browser 2 on a PC or a mobile terminal (for example, a mobile phone, a smartphone, or the like).

  Specifically, the information acquisition system 1 includes display completion event acquisition means 3. 3. Display content acquisition means 4. Browser browsing history storage means Event continuous state setting means6. Event sequence acquisition means 7. Transition state determination means8. Event table9. This is realized by the display content saving instruction means 10. Here, the storage means 5 and the event table 9 can be constructed in a storage device such as a memory (RAM) or a hard disk drive device.

  The event acquisition means 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 detected event information included in the event information. This detection event information includes at least the detection date and time and the detection event URL, and an “event ID” is assigned to each detected display completion event. This detected event information is output to the continuous state setting means 6 and the event string acquisition means 7.

  The display content acquisition unit 4 acquires the display content displayed by the Web browser 2 when the display completion event is detected by the display completion event acquisition unit 3. For example, display URL. html file. A thumbnail image of the display content is acquired from the Web browser 2.

  The continuous state setting means 6 detects the busy state of the web browser 2 based on the detected event information output from the display completion event acquisition means 3, and if a busy state is detected, the display completion event is continuously generated. judge. If it is determined here that the display completion event is continuously generated, the event continuous state data D is output to the event sequence acquisition means 7.

  The event sequence acquisition unit 7 determines a boundary of the continuous state data D output from the continuous state setting unit 6 and acquires a continuous event sequence. The detection event information output from the event acquisition means 3 is used for the determination of the boundary.

  For example, if the time interval between display completion events exceeds a threshold value, it can be determined that the boundary is the continuous state data D. Further, if the host name or the like is different between URLs of display completion events, it can be determined that the boundary of the continuous state data D is present. The event sequence acquired here is output to the determination means 8.

  The determination unit 8 analyzes the event sequence output from the event sequence acquisition unit 7 and detects the highest frame (the frame page), thereby causing a transition that causes a web page transition, for example, a transition of an upper frame or Specify the transition of a single lower frame. EventID. Of the display completion event of the frame detected here. Date and time. The detected event URL is recorded in the event table 9.

  The storage instructing unit 10 monitors the recorded contents of the event table 9, and if an event ID of a display completion event is recorded in the event table 9, a Web browser corresponding to the display completion event is displayed to the display content acquiring unit 4. 2 is instructed to be stored in the storage means 5 as a browser browsing history.

<< Processing example of the information acquisition system 1 >>
Hereinafter, a processing example of the information acquisition system 1 will be described. Here, the continuous state setting unit 6 sets the flag of the continuous state data D to ON when it receives the detected event information output from the event acquisition unit 3. While the Web browser 2 is in a busy state after this setting, the flag of the continuous state data D remains set to ON, and the Web browser 2 is not in a busy state and if the preset threshold value elapses, the continuous The flag of the status data D is switched to OFF setting.

  At this time, the event sequence acquisition means 7 cuts out a continuous event sequence with the portion switched to the OFF setting (between display completion events) as the boundary point of the continuous state data D. That is, the event sequence of the display completion event that occurs when the flag of the continuous state data D is set to ON is cut out. Processing examples 1 to 4 will be described for each event sequence extracted here.

(1) Processing example 1
An example of processing when the lower frame is read prior to the upper frame will be described with reference to FIG. Here, as an example, it is assumed that the threshold is set to “30 seconds” (the same applies to Processing Examples 2 to 4). In this example process:
The flag of the continuous state data D is switched to the OFF setting during the event ID = 1.2 from the site xxx to the site abc and the event ID = 6.7 from the site abc to the site yyy. Therefore, the event sequence acquisition unit 7 cuts out the display completion event having eventID = 2 to 6 as a continuous event sequence and outputs it to the determination unit 8.

  At this time, the determination means 8 analyzes the received continuous event sequence and detects the highest frame in the event sequence. EventID of the display completion event of the detected frame. Date and time. The detected event URL is recorded in the event table 9.

  In this processing example, eventID = 6 that occurs last is detected as the highest level, and the transition of “top.html” is identified as the cause of the Web page transition. When this event ID = 6 detected event URL or the like is recorded in the event table 9, the determination means 8 instructs the storage of the browser browsing history in the storage means 5.

(2) Processing example 2
A processing example of a display completion event in which Web browsing in FIG. 3, that is, reading of a lower frame occurs independently will be described based on FIG.

  In this processing example, the event sequence acquisition unit 7 cuts out a display completion event with eventID = 2 to 4 as a continuous event sequence and outputs it to the determination unit 8. In response to this, the determination unit 8 analyzes the event string of eventID = 2 to 4, detects eventID = 4 as the highest level, and the detected event URL and the like are recorded in the event table 9.

  Here, in FIG. 7, event sequences similar to eventID = 2-4 are included as eventID = 3-5 in FIG. However, in FIG. 6, since a higher page transition is detected as eventID = 6, eventID = 3 to 5 is not identified as an independent page transition, but is identified as a transition of a lower frame accompanying the upper frame. The On the other hand, in FIG. 7, since eventID = 4 is detected as the highest level, it is specified as a single transition of the lower frame.

(3) Processing example 3
Based on FIG. 8, a processing example of the Web browsing of FIG. 4, that is, a display completion event in which the event generation order of FIG. In this processing example, the event sequence acquisition unit 7 cuts out eventID = 2 to 6 as a continuous event sequence and outputs the event ID to the determination unit 8. In response to this, the determination means 8 analyzes the event string of eventID = 2 to 6, and eventID = 5 is detected as the highest rank. A detection event URL of the display completion event with eventID = 5 is recorded in the event table 9.

  In this processing example, unlike the processing example 2 in FIG. 6, the last display completion event in the event sequence is not detected as the highest level. This is because the event ID = 5.6 is generated by changing (reversing) the original generation order. At this time, the information acquisition system 1 can accurately detect the occurrence order disturbance.

  That is, according to the system of Patent Document 1, since the occurrence of the related display completion event is determined to be complete when the transition of the top frame of eventID = 5 is detected, the display completion event of eventID = 6 is different. It is determined that the web page transitions. Therefore, excessive web page transitions are detected and recorded in the event table 6.

  On the other hand, according to the information acquisition system 1, the event ID = 5.6 is generated in the order of occurrence of the event ID = 5.6 because the event sequence acquisition means 7 cuts out the event sequence of the display completion events generated continuously. In addition, any event ID = 5.6 is included in the extracted event sequence.

  Since the highest level in the extracted event sequence is detected, even if there is a sequential change between the transition of the upper frame and the transition of the lower frame, a process of absorbing this is realized. That is, in the event sequence of the display completion event 4-1.4-2.4-3.4-4.4-5 in FIG. 4, the display completion event 4-4.4-5 is replaced with the original order. Even in this case, the information acquisition system 1 detects the highest rank from the event strings 4-1 to 5-5.

  As a result, the transition of the upper frame or the transition of the lower frame alone is investigated, and the lower frame transition of 4-1.4-2.4-3.4-5 occurs along with the upper frame transition of 4-4. Identified. Therefore, a detection event URL with eventID = 5 is recorded in the event table 9.

  As a result, even if the transition of the upper frame and the transition of the lower frame are interchanged with each other in the original generation order, it can be accurately recorded in the event table 9, and recording of excessive web page transition can be suppressed. Therefore, the browser browsing history of the user with respect to the Web page divided into frames can be accurately stored in the storage unit 5 without being affected by disturbances to the display completion event generated by the Web browser 2. .

(4) Processing example 4
As shown in FIG. 9, an example of processing when the lower frame is independently read after the lower frame is read prior to the upper frame will be described. Here, it is assumed that the Web page transition is performed from the display completion event 9-1 to 9-5, and then the transition of only “frame22.html” is performed at the display completion event 9-6. At this time, if a display completion event is represented as shown in FIG.
-Between event xxx moving from site xxx to site abc = 1.2-Between event ID = 6.7 where frame 22 transitions within site abc-The continuous state between event ID = 7.8 moving from site abc to site yyy Data D switches to OFF setting. Therefore, the event sequence acquisition unit 7 cuts out eventID = 2 to 6 as a continuous event sequence and outputs it to the determination unit 8. At this time, since the time interval between eventID = 6.7 exceeds the threshold value, eventID = 7 is not included in the event string, and the determination unit 8 records the event table 9 as another Web page transition.

  As described above, according to the information acquisition system 1, it is possible to appropriately specify the transition that causes the web page transition from the event sequence of each display completion event in the processing examples 1 to 4. Therefore, regardless of the occurrence order of the display completion event, the display completion event causing the Web page transition is recorded in the event table 9. As a result, the display content of the correct Web page is stored in the storage means 5 as a browser browsing history. In this respect, the browser browsing history can be used efficiently.

≪Programs≫
The present invention can also be configured as a Web page information acquisition program that causes a computer to function as each means 3 to 10 of the information acquisition system 1. According to this program, it is possible to cause a computer to execute part or all of the processing contents of the means 3 to 10.

  The program can be provided through a network such as a website or e-mail. The program is stored in a recording medium such as a CD-ROM, DVD-ROM, CD-R, CD-RW, DVD-R, DVD-RW, MO, HDD, BD-ROM, BD-R, or BD-RE. It is also possible to record, 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.
