Description

The present invention relates to a tracking information analysis system, a server device, a tracking information analysis method, and a tracking information analysis program.

In recent years, PDF (Portable Document Format) files have become widely used for business documents, as they are not affected by the usage environment of the user's terminal, and can be printed or displayed on a screen page by page, and the layout remains unchanged. . Generally, a PDF file is generated by creating a document file in which document contents are described using an application program such as a spreadsheet or document creation program, and converting the created document file into a PDF format.

PDF files generated in this way are presented to users as business documents in various situations. However, when presenting PDF files such as catalogs, various materials, contracts, etc. to users, it is difficult for the provider to know whether the user has read the content that the user wants to pay attention to or check. Regarding web pages, a technique has been disclosed that acquires information regarding display locations of a web page at predetermined time intervals and outputs the viewing time at each display location as the page viewing status (see Patent Document 1).

The PDF file storage unit 110 stores resource IDs that identify PDF files in association with the PDF files. A PDF file describes page content including the contents of each page to be displayed on the screen or printed, and specified area information consisting of the area of the specified area in the PDF file, a specified area ID that identifies each specified area, and other information. . The region of the specified area in a PDF file is described as the upper left coordinates, width, and height of a rectangle of the specified area when the origin is the upper left of each page when the PDF file is displayed or printed. Other information includes keywords indicating the contents of the designated area. The PDF file storage unit 110 may be a database that associates resource IDs and PDF files, or may have a configuration in which the resource ID is used as a folder name and PDF files are stored under the folder, or other configurations.

FIG. 2 is an explanatory diagram showing an example of the data structure of a PDF file stored in the PDF file storage unit 110. As shown in FIG. 2, the PDF file 21 includes page content (1 page), page content (2 pages), designated area information, and the like. The page content (1 page) and the page content (2 pages) are written in the visible area, and the designated area information is written in the invisible area.

Screen display example (or print example, hereinafter referred to as screen display example) 22 is a screen display example corresponding to the description of page content (1 page), and screen display example 23 is a screen display example corresponding to the description of page content (2 pages). This is an example of a corresponding screen display.

The designated area information 26 describes information regarding each designated area. As the designated area information of explanation A, the number of pages of the content "1", the designated area ID "tagA" that identifies the designated area of explanation A, and the information indicating the region of the designated area in the PDF file are described. In addition, keywords for explanation A, etc., which are not shown, are described. Although the example shown in FIG. 2 is written in JSON format, it may be written in other formats. The same applies to explanation B. Zero to multiple specified areas may be set for each page of the PDF file, and each area may partially overlap or one area may be completely included in another area.

The tracking information storage unit 120 stores tracking information generated from an operation on a screen displaying a PDF file, which is received by the information terminal device 200 operated by a user viewing the PDF file. FIG. 3 is an explanatory diagram showing an example of an operation on a PDF file and tracking information corresponding to the operation. As shown in FIG. 3, a page image 32 of a PDF file is arranged on the entire viewer area (or entire browser area, hereinafter referred to as the entire area) 31, and the viewer display area (or browser entire area) 31 is arranged on the screen of the information terminal device 200. The PDF file in the display area (hereinafter referred to as display area) 33 is displayed.

In the operation example shown in Figure 3, a PDF file consisting of one page and two pages selected or instructed by the user is displayed by starting a PDF viewer or a web browser, and from the time the user starts displaying the PDF file until the end. operations (specifically, operations of scrolling, tapping, enlarging, and ending display) and tracking information corresponding to the operations are shown in chronological order. In the operation shown in FIG. 3, for ease of explanation, the operation is detected every second and tracking information is generated, but in reality, tracking information is generated from the operation every millisecond. Note that the interval for detecting user operations does not need to be limited to 1 millisecond, and may be longer or shorter, depending on the content of the PDF file, the device operated by the user, user information (attributes such as age), etc. You can change it accordingly. Further, by setting the interval at which operations are detected to be longer than 1 millisecond, the tracking information is thinned out (or rounded), and the amount of data can be reduced. Further, page information regarding each page of the PDF file, which is a premise of the tracking information, is stored in the tracking information storage unit 120 as shown in FIG. The page information stores the page number, size information for each page in the entire area 31 (top left coordinates, width, and height), and screen magnification.

The transmitting/receiving unit 101 receives the resource ID from the information terminal device 200, obtains the PDF file associated with the resource ID from the PDF file storage unit 110, and transmits it to the information terminal device 200. The transmitting/receiving unit 101 receives tracking information from the information terminal device 200 and stores it in the tracking information storage unit 120.

The transmitting/receiving unit 101 receives the resource ID and the analysis instruction from the information terminal device 300 and transmits the analysis result to the information terminal device 300. The transmitting/receiving unit 101 receives a PDF file from the information terminal device 300 and transmits the PDF file (or a web page that displays the PDF file) to the information terminal device 300. The transmitting/receiving unit 101 receives designated area information in the PDF file. The transmitting/receiving unit 101 transmits a PDF file (or a web page displaying a PDF file) to the information terminal device 400 and transmits tracking information to the information terminal device 400.

When displaying a PDF file as a web page on a web browser running on the information terminal device 200, the web page generation unit 102 generates a web page that displays the PDF file.

The cumulative time calculating unit 103 calculates the cumulative time for each designated area by integrating the time during which the designated area is displayed in the display area, based on the tracking information and designated area information stored in the tracking information storage unit 120. Note that the cumulative time may be determined by not only adding up the time during which the designated area is actually displayed, but also by converting the user's operation into the display time of the designated area and adding it to the cumulative time. For example, indicating that the user has paid attention to or confirmed the specified area, such as by tapping or dragging a character string within the specified area, or by enlarging the area containing the target area. Regarding the tracking information, the tracking information may be converted into display time and added to the cumulative time. Furthermore, in the process of converting a predetermined operation into display time, weighting may be performed depending on the type of operation and then the conversion may be performed into display time.

The analysis result generation unit 104 generates an analysis result indicating the user's degree of attention to or confirmation of the designated area, based on the cumulative time for each designated area calculated by the cumulative time calculation unit 103. The analysis results are generated for each user from the tracking information of each user. This makes it possible to generate analysis results that indicate which parts of the PDF file each user paid attention to or checked. As another example, the analysis result generation unit 104 generates analysis results from tracking information collected not only from one specific user but from a plurality of users. In that case, analysis results may be generated using tracking information of user groups classified by user information such as gender and age.

When the resource ID generation unit 105 receives a PDF file to be analyzed, it generates a resource ID that is information that can uniquely identify the PDF file in the tracking information analysis system 10. The resource ID generation unit 105 stores the resource ID and the PDF file in the PDF file storage unit 110 in association with each other. Further, the resource ID may be a file name or the like as long as it is information that allows the tracking information analysis system 10 to uniquely identify the PDF file. Note that instead of storing the resource ID and the PDF file in association with each other in the PDF file storage unit 100, the resource ID may be added to the PDF file.

The PDF file appending unit 106 appends the designated area information transmitted from the information terminal device 300 to the PDF file, and stores the PDF file with the designated area information added in the PDF file storage unit 110.

The preview information acquisition unit 107 acquires the preview information from the PDF file if the preview information is written in the PDF file. The preview information is information regarding a destination (a device different from the information terminal device 200) to which tracking information is sent in order to reproduce the operation acquired by the information terminal device 200 on a device different from the information terminal device 200.

Next, the information terminal device 200, the information terminal device 300, and the information terminal device 400 that constitute the tracking information analysis system 10 along with the server device 100 will be explained.

The transmitting/receiving unit 301 transmits designated area information to the server device 100.

The operation display unit 302 accepts operations and the like by the user and displays the results of the operations and the like. The operation display unit 302 displays a PDF file (or a web page showing the PDF file on a web browser) using a PDF viewer, and accepts input of designated area information. The hardware of the operation display section 302 is the same as that of the operation display section 202 described above.

The information terminal device 400 is a computer that receives tracking information of the information terminal device 200 and reproduces operations on the information terminal device 200, and is a PC, a tablet terminal, a smartphone, or the like. The information terminal device 400 includes a transmitting/receiving section 401, an operation display section 402, and the like.

The transmitting/receiving unit 401 transmits and receives data to and from the server device 100 via the network N. The transmitting/receiving unit 401 receives a PDF file from the server device 100. The transmitting/receiving unit 401 receives tracking information from the server device 100.

The operation display unit 402 displays a PDF file (or a web page showing the PDF file in a web browser) using a PDF viewer, and reproduces and displays the operation on the information terminal device 200 based on the tracking information sent from the server device 100. . The hardware of the operation display section 402 is similar to the operation display section 202 described above.

A tracking information collection process executed by the tracking information analysis system 10 configured as described above will be described. FIG. 4 is a flowchart showing a tracking information collection processing procedure executed by the server device 100 and the information terminal device 200.

In the information processing device 200, the operation display unit 202 accepts selection of a resource ID (step S401). The resource ID selected here is obtained by, for example, presenting a PDF file stored in the PDF file storage unit 110 included in the server device 100 and instructing the file name, thumbnail, etc. of the presented PDF file. Alternatively, the resource ID may be acquired by clicking or tapping the URL of a PDF file written in an email, chat, or the like. The transmitter/receiver 201 transmits the resource ID to the server device 100 (step S402).

The transmitting/receiving unit 101 of the server device 100 receives the resource ID from the information processing device 200 (step S403). The transmitting/receiving unit 101 acquires the PDF file associated with the resource ID from the PDF file storage unit 110 (step S404). The transmitting/receiving unit 101 transmits the PDF file to the information terminal device 200 (step S405). Note that if the PDF file is to be displayed as a web page on the information terminal device 200 at this time, the web page generation unit 102 generates a web page for displaying the PDF file, and the transmitting/receiving unit 101 transmits the web page to the information terminal device 200. do.

The transmitting/receiving unit 201 of the information processing device 200 receives the PDF file from the server device 100 (step S406). The operation display unit 202 displays the PDF file using the PDF viewer (step S407). When a web page is sent from the server device 200, the web browser displays the PDF file that is the web page. The operation display unit 202 accepts the user's operation on the screen displaying the PDF file (step S408). The operation display unit 202 displays a screen according to the user's operation (step S409). The tracking information generation unit 203 generates tracking information from the user's operation (step S410).

For example, in the operation from activation to scroll shown in FIG. 3, the operation display unit 202 displays a PDF file on the screen at the time of activation, and further displays a PDF file corresponding to the scroll operation on the screen. The tracking information generation unit 203 generates “type=screen operation, x=0, y=0, w=150, h=120” (coordinates of the top left of the display area in the entire area), which is information regarding the screen displayed at startup. , width and height), “vTime=4000” (4 seconds), which is the display time from startup until the scroll is operated, and “s=1” (100%), which is the screen magnification at that time. Generate as information. Furthermore, when a tap operation is performed, the tapped position is used as tracking information, and the screen display at the time of the tap is generated as tracking information. By generating the screen display at the time of tap as tracking information, the cumulative time calculation unit 103 of the server device 100 can easily calculate the display time of the designated area, similarly to other operations.

The transmitting/receiving unit 201 transmits tracking information to the server device 100 (step S411). The operation display unit 202 determines whether the user's operation has been completed (step S412). More specifically, it is determined whether an instruction to end the display has been accepted. If it is determined that the user's operation has ended (step S412: Yes), the process ends. If it is determined that the user's operation has not been completed (step S412: No), the process returns to step S408, and tracking information according to the user's operation is generated.

The transmitting/receiving unit 101 of the server device 100 receives tracking information from the information terminal device 200 (step S413). The transmitting/receiving unit 101 stores the tracking information in the tracking information storage unit 120 (step S414).

In this way, information about the screen displayed through operations such as scrolling, tapping, and enlarging is generated as tracking information and stored in chronological order, so that it is possible to remember which part of the PDF file entered the user's field of view. You can keep it.

In addition to remembering which part of the entire area was displayed, it also stores operations on character strings and images in the PDF file, such as the coordinates tapped on the screen, the character string dragged, the coordinates the pointer moved, etc. By storing the information as tracking information, operations that are considered to have been noticed or confirmed by the user can be used in analysis processing.

Furthermore, before accepting the selection of the resource ID of the information terminal device 200, by executing a login process between the server device 100 and the information terminal device 200, the user who operates the information terminal device 200 is identified, and the user It becomes possible to link information. This makes it possible to analyze individual users or groups of users having the same user information.

Next, tracking information analysis processing executed by the server device 100 and the information terminal device 300 will be described. FIG. 5 is a flowchart showing a tracking information analysis processing procedure executed by the server device 100 and the information terminal device 300.

The operation display unit 302 of the information terminal device 300 receives input of a resource ID and an analysis instruction (step S501). In addition to the resource ID and analysis instruction, when analyzing the operations of individual users, the operation display unit 302 accepts input of a user ID that identifies the user who is the target of tracking information analysis. Furthermore, when performing analysis on a group of users narrowed down based on user information, the operation display unit 302 accepts input of search conditions using user information. The transmitting/receiving unit 301 transmits the resource ID and the analysis instruction to the server device 100 (step S502). Further, when analyzing operations of individual users, a user ID is transmitted, and when analyzing a predetermined group of users, a search formula using user information is transmitted.

The transmitting/receiving unit 101 of the server device 100 receives the resource ID and the analysis instruction (step S503). The transmitting/receiving unit 101 acquires the PDF file associated with the resource ID from the PDF file storage unit 110 (step S504). The analysis result generation unit 104 acquires tracking information according to the resource ID (and user ID) from the tracking information storage unit 120 (step S505). Note that the tracking information is stored in the tracking information storage unit 120 in association with the resource ID and the user ID.

The analysis result generation unit 104 generates an analysis result using the tracking information and the PDF file in response to the analysis instruction transmitted from the information terminal device 300 (step S506). Details of the process will be described later using FIG. 6. The transmitting/receiving unit 101 transmits the analysis result to the information terminal device 300 (step S507).

The transmitting/receiving unit 301 of the information terminal device 300 receives the analysis result from the server device 100 (step S508). The operation display unit 302 displays the analysis results on the screen (step S509).

The tracking information analysis process executed in step S506 described above will be described in detail. FIG. 6 is a flowchart showing a tracking information analysis processing procedure executed by the server device 100.

The cumulative time calculation unit 103 acquires designated area information to be written in the PDF file (step S601). The cumulative time calculation unit 103 calculates the cumulative time for each designated area from the tracking information and the designated area information (step S602). More specifically, the cumulative time calculation unit 103 determines whether or not the display area included in the tracking information includes the designated area, and if it is determined that the designated area is included, the cumulative time calculation unit 103 determines whether the display area included in the tracking information includes the designated area. Add the display time to the cumulative time of the specified area. Note that the coordinate system of the PDF file displayed on the screen and the coordinate system written in the PDF file may have different units of length, etc., but by unifying them to one of the coordinate systems, a discrepancy will occur. It is possible to determine whether or not the designated area is included in the display area without having to worry about the display area. The analysis result generation unit 104 generates an analysis result indicating the user's degree of attention to or confirmation of the designated area (step S603).

A specific example of the analysis results is as follows: (a) A heat map is generated that expresses the amount of accumulated time for each designated area by the difference in color or shade of color superimposed on the designated area. (b) Calculate the viewing rate for each designated area from the total viewing time and the cumulative time for each designated area. (c) Write keywords in the designated area information and show the keywords and cumulative time of the designated area in association. Generate analysis results (d) In (c), generate analysis results that associate keywords and cumulative times in descending order of cumulative time, or in order of appearance in the PDF file (e) (d ), generate an analysis result that represents the cumulative time in a graph such as a bar graph (f) Describe the specified criteria in the designated area information, , the number of taps, etc., or a combination thereof).

In this way, in the tracking information analysis process, the amount of time that the user actually displays on the screen the specified area that the PDF file provider, etc. wants them to pay attention to or check is calculated as the cumulative time. This makes it possible to determine whether the user has paid attention to or confirmed the designated area. Analysis results can be generated at any time after a user views a PDF file. Furthermore, by generating a heat map indicating the degree of attention or confirmation for each designated area and superimposing it on the PDF file, it is possible to easily understand which designated area the user has paid attention to or confirmed. Furthermore, by adding keywords indicating the contents of the designated area to the designated area information and using the keywords in the analysis results, users' interests can be easily summarized.

In addition, when analyzing individual user tracking information, the analysis results can indicate that a specific user has paid attention to or checked a specified area of a PDF file, and can measure the user's individual interest in and understanding of the content of the PDF file. be able to. In addition, when tracking information of multiple users is analyzed, it is possible to understand the viewing trends of the user who presented the PDF file, and in the case of tracking information of a group of users narrowed down by user information, it is possible to understand the viewing trends of the user who presented the PDF file. Viewing trends can be understood.

Tracking information such as taps, where the screen size does not change due to user operations, can be converted to cumulative time according to predetermined rules and then added to the cumulative time to more accurately gauge user interest. . Alternatively, a heat map showing the tapped coordinates, etc., may be generated separately from the cumulative time, and an analysis result from a different viewpoint may be generated.

Instead of the designated area described above, the PDF file displayed on the screen may be divided into meshes, the cumulative time of each area of the mesh may be calculated, and a heat map may be generated based on the cumulative time of each area of the mesh. Furthermore, a heat map indicating at which part of the PDF file the user stopped viewing may be generated based on the accumulated time of each line of the PDF file, exit coordinates when viewing the PDF file, and the like.

When generating an analysis result according to an analysis instruction from a user, the analysis method may be one of the above-mentioned individual analysis methods or a combination of a plurality of analysis methods. In addition, we can calculate the total number of accesses for each content PDF file, the number of accesses per month, date, hour, and day of the week, the ratio of user information (age, generation, gender, etc.), and the number of accesses for each content PDF file. Popularity rankings, popular product rankings within content, and other information may be used as analysis results.

Next, the PDF file/designated area registration process executed by the server device 100 and the information terminal device 300 will be described. FIG. 7 is a flowchart showing the PDF file/designated area registration processing procedure executed by the server device 100 and the information terminal device 300. Although it is described for convenience that the information terminal device 300 that executed the tracking information analysis process also executes the PDF file/designated area registration process, the PDF file/designated area registration process and the tracking information analysis process are performed by the same device. It may be implemented or executed by a different device.

The transmitting/receiving unit 301 of the information terminal device 300 transmits the PDF file to the server device 100 (step S701). Here, the PDF file is a PDF file that is a target of tracking information analysis, and is, for example, a document such as a catalog, various materials, or a contract.

The transmitting/receiving unit 101 of the server device 100 receives the PDF file from the information terminal device 300 (step S702). The resource ID generation unit 105 generates a resource ID that uniquely identifies the PDF file (step S703). The resource ID generation unit 105 stores the resource ID and the PDF file in association with each other in the PDF file storage unit 110 (step S704). The transmitter/receiver 101 transmits the PDF file (step S705). In the information terminal device 300, when displaying a PDF file using a PDF viewer, the PDF file is transmitted, and when displaying the PDF file using a web browser, a web page for displaying the PDF file is generated by the web page generation unit 102. , submit the generated web page.

The transmitting/receiving unit 301 of the information terminal device 300 receives the PDF file from the server device 100 (step S706). The operation display unit 302 displays the PDF file on the screen (step S707). The operation display unit 302 receives input of designated area information in the PDF file (step S708). The transmitting/receiving unit 301 transmits the designated area information to the server device 100 (step S709).
