Description

  The present invention relates to a work evaluation apparatus, a work evaluation method, and a program configured by an information processing apparatus capable of editing a digital album composed of digital content jointly.

  In recent years, with the widespread use of digital cameras and digital movies, opportunities for taking pictures and videos have increased. Along with that, it has become possible to process and enjoy the photos and videos taken. As an example, devices that can arrange a favorite photo on an album template (mounting sheet) and create a digital album have appeared. The user can easily create a digital album composed of a plurality of album pages using photos taken at events such as “athletic meet” and “wedding”. In addition to creating such a digital album alone, it has become possible to create a digital album jointly by a plurality of people via a network.

  However, when there are many digital albums created jointly in the device, it takes a considerable time to search for an album or album page desired by the user. Therefore, it is desired to identify and present an album or album page that is highly important to the user by a device that stores a digital album.

  Here, in order to identify albums with high importance, prioritization is performed by analyzing the target image data and setting the importance of image data with many characteristic scenes and faces high. System exists.

  There is also a technique for determining the importance of image files and document data based on information such as the number of references, reference time, number of prints, number of edits, and edit time (see, for example, Patent Document 1 and Patent Document 2).

JP 2010-128518 A JP 2005-260355 A

  However, in the prior art, it is possible to prioritize based on the result of image analysis, that is, the contents shown in the photograph, but it is difficult to prioritize based on the editing process of the work. is there. In addition, there is a problem that advanced image analysis is difficult to realize on a resource-constrained embedded device.

  Further, in the systems described in Patent Document 1 and Patent Document 2, even if the target data is edited by one user or edited by a plurality of people, the editing contents are the same. Since the importance is set to be the same, it is not possible to obtain an importance based on editing work by a plurality of people, for example, a work that is created by a plurality of people like a digital album.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a work evaluation apparatus that realizes prioritization of works based on an editing history by a plurality of persons for a work that is created by a plurality of persons. And

  In order to solve the conventional problem, the work evaluation device of the present invention is a work evaluation device that evaluates a work edited by a plurality of users, and stores editing history information on the work by the plurality of users. Importance level for storing evaluation value information in which an edit history information storage unit and at least one of information on editing for the work and information on the plurality of users are associated with evaluation value information for evaluating the importance of the work A calculation information storage unit; and a work importance calculation unit that calculates the importance of the work based on the editing history information and the evaluation value information.

  Thereby, it becomes possible to prioritize works based on the editing history by a plurality of persons for works that are co-created by a plurality of persons.

  According to the work evaluation apparatus of the present invention, it is possible to prioritize works based on editing histories by a plurality of persons, for works that are jointly created by a plurality of persons. In addition, since it is a technique that does not use advanced image analysis, it can also be applied to embedded devices with limited resources.

Via the message display screen 307, the user can edit the digital album while performing message communication in a chat format with the users participating in the editing work of the digital album.

  The work information storage unit 103 stores the work in which the editing operation is reflected by the work editing unit 102. In this embodiment, a work is composed of work templates, photographs, decoparts, handwritten data, and audio data, which are entities constituting the work, and work management information indicating information for composing the work. The work information storage unit 103 stores the correspondence between the entities constituting the work and the work management information for each work.

  An example of the work management information is shown in FIG. In the example of FIG. 4, a digital album composed of a plurality of pages is taken as an example to configure a work in association with a work ID for identifying the digital album and a work page ID for identifying a page in the digital album. As information, a work template file, a photo file, a photo position, a deco part file, a deco part position, a handwritten comment file, a handwritten comment position, and an audio file are described.

  The work template file is information for identifying a file used as an album template. In FIG. 4, a file name is used as an example. In the example of FIG. 4, the file having the file name “template001.jpg” is used for the page assigned the work page ID1 in the work assigned the work ID1.

  The photo file is information for identifying a photo arranged in the album template. In FIG. 4, a photo file name is used as an example. The example of FIG. 4 indicates that a file having a file name “photo001.jpg” is used for a page to which a work page ID1 is assigned in a work to which a work ID1 is assigned.

  The photo position is information indicating the arrangement position of the photo in the album template. In FIG. 4, as an example, the coordinates of each vertex when the rectangular photo is arranged in the album template are used. In the example of FIG. 4, for the page assigned the work page ID1 in the work given the work ID1, the coordinates of each vertex when the photo with the file name “photo001.jpg” is arranged in the album template is (x1 , Y1), (x2, y2), (x3, y3), (x4, y4).

  The decoparts file is information for identifying the decoparts arranged in the album template, and in FIG. 4, the file name of the decoparts is used as an example. In the example of FIG. 4, the file having the file name “deco001.png” is used for the page assigned the work page ID1 in the work assigned the work ID1.

  The decopart position is information indicating the arrangement position of the decoparts in the album template. In FIG. 4, as an example, when the decoparts are arranged in the album template, the coordinates of the vertices of the rectangle enclosing the decoparts are used. . In the example of FIG. 4, when a decopart having a file name “deco001.jpg” is placed in an album template for a page to which a work page ID1 is assigned in a work to which work ID1 is assigned, a rectangle that includes the decoparts is included. The coordinates of the vertices are (x5, y5), (x6, y6), (x7, y7), and (x8, y8).

  The handwritten comment file is information for identifying the handwritten comment arranged in the album template, and in FIG. 4, as an example, a file name for storing the handwritten comment as electronic data is used. In the example of FIG. 4, a file with the file name “comment001.png” is used for the page assigned the work page ID1 in the work given the work ID1.

  The handwritten comment position is information indicating an arrangement position of the handwritten comment in the album template. In FIG. 4, as an example, when the handwritten comment is arranged in the album template, the coordinates of each vertex of the rectangle that includes the handwritten comment Is used. In the example of FIG. 4, regarding the page assigned the work page ID1 in the work assigned the work ID1, when the handwritten comment having the file name “comment001.jpg” is placed in the album template, the handwritten comment is included. The coordinates of the vertices of the rectangle are (x9, y9), (x10, y10), (x11, y11), and (x12, y12).

  The audio file is information for identifying the audio file that is reproduced when browsing the digital album. In FIG. 4, the file name of the audio file is used as an example. In the example of FIG. 4, when browsing the page assigned the work page ID 1 in the work assigned the work ID 1, a file whose file name is “voice001.mp3” is used.

  FIG. 4 shows an example in which one photo, decopart, handwritten comment, and audio file are arranged on each album page, but a plurality of photographs, decoparts, and handwritten comments are arranged on one album page. It can also be considered. In this case, for example, if the information about the file names and positions of all the photos, decoparts, and handwritten comments placed on one work page are included in one line record of the work management information shown in FIG. Good.

  Returning to the description of FIG. 1, the editing history acquisition unit 104 acquires information regarding the editing operation reflected in the work by the work editing unit 102 as editing history information.

  Here, the editing history information is managed in association with information related to the editing operation for the predetermined portion for each predetermined portion of the work. Here, the predetermined part of the work includes (1) the whole work, (2) one unit that is organized when viewing a work such as one page in a digital album consisting of multiple pages, and (3) a decopart or comment There are various parts that make up a work such as, but any of them may be used.

  The editing history information storage unit 105 stores the editing history information acquired by the editing history acquisition unit 104.

  FIG. 5 is a diagram illustrating an example of editing history information stored in the editing history information storage unit 105. In the example of FIG. 5, as an example of a digital album composed of a plurality of pages, information relating to an editing operation is associated with a work ID for identifying a digital album and a work page ID for identifying a page in the digital album. The number of editors, distance, data amount, editing contents, and participant names are described.

  The number of editors is information indicating the number of users who have performed an editing operation on a predetermined part of the work. In the example of FIG. 5, it is shown that the number of editors is 3 for the page assigned the work page ID 1 in the work assigned the work ID 1.

  The distance is information indicating a physical distance between a plurality of users who performed an editing operation on a predetermined part of the work. Here, the physical distance between the plurality of users can be calculated from, for example, the place where the user performed the editing operation. When the user performs an editing operation using a portable terminal such as a smartphone as the terminal 109, the location where the user performed the editing operation can be specified using information such as GPS. Moreover, when the information regarding the address of a some user is obtained, you may calculate the physical distance between several users from the information regarding the position of the address. In addition, the physical distance may be calculated for a specific user and other users among a plurality of users, or may be calculated for a combination of all users. In the example of FIG. 5, the distance between the user A and the user B is 80 km, the distance between the user A and the user C is 20 km, and these are the pages assigned the work page ID1 in the work given the work ID1. The total of 100 km is managed as the distance 204.

  The amount of data is information regarding the amount of messages sent between a plurality of users when an editing operation is performed on a predetermined part of the work. As the amount of messages, for example, the total size of message data transmitted from each user when messages are exchanged by chat using the message display screen 307 of the work editing screen as shown in FIG. 3 is used. Can do. In the example of FIG. 5, 700 bytes, 200 bytes, 100 bytes, which are the total sizes of message data transmitted by the users A, B, and C, for the pages assigned the work page ID1 in the works assigned the work ID1, and these A total of 1000 bytes is managed as the data amount 205.

  The editing content is information indicating the content of the editing operation for a predetermined part of the work. At this time, the content of the editing operation and the user who performed the editing operation may be managed in association with each other. In the example of FIG. 5, the user A selects / replaces a photo for the page assigned the work page ID1 in the work assigned the work ID1, and the user B adds a decopart and adds a handwritten comment. The fact that the user C has selected / replaced the photograph is managed as the editing content 206.

  The participant name is information indicating a user name of a user who has performed an editing operation on a predetermined part of the work. In the example of FIG. 5, A, B, and C are managed as the participant names for the page assigned the work page ID 1 in the work assigned the work ID 1.

  Needless to say, the data structure of the editing history information is not limited to the example of FIG. For example, when the content of the editing operation and the user who performed the editing operation are managed in association with each other as in the editing content in FIG. 5, the number of editors and the names of participants can be obtained using this information. Therefore, these pieces of information need not be managed as editing history information.

  Further, as the editing history information, the editing location, the edited user, and the content of the editing operation may be managed for each editing date and editing date. Then, the editing history information shown in the example of FIG. 5 may be obtained by counting the editing history information managed in such a manner.

  Returning to the description of FIG. 1, the work importance calculation unit 106 calculates the importance of the work based on the editing history information and the importance calculation information. In the present embodiment, the importance level of a work is calculated based on at least one of information on a plurality of users who edited the work and information on the contents of the editing operation. Further, the importance calculation information is assumed to be composed of reference information regarding importance calculation rules and evaluation value information defining points for importance calculation for each content of the editing history.

  An example of the reference information is shown in FIG. In the example of FIG. 6, importance calculation rules, which are definition information for calculating importance, are managed in association with rule IDs for identifying importance calculation rules. Further, in order to identify importance calculation rules that are valid in the importance calculation processing, an effective flag is also managed. In the example of FIG. 6, “participant priority” associated with rule ID = 1 is a rule indicating that a work with a large number of people who participated in editing the work is preferentially displayed. The “point priority” associated with the rule ID = 2 is a rule indicating that the points are totaled based on the editing history information of the works, and the works are displayed in descending order of the total points. The “individual participant priority” associated with the rule ID = 3 is a rule indicating that the user who wants to view the work preferentially displays the album that participated in the editing. The “ID order” associated with rule ID = 4 selects the importance calculation rules stored in the reference information shown in FIG. 6 in the order of rule IDs, and is set so that the importance is high according to the selected importance calculation rules. It is a rule which shows displaying the done work.

  Next, an example of evaluation value information is shown in FIG. In the example of FIG. 7, in correspondence with the information managed by the editing history information shown in FIG. 5, evaluation value information about distance, evaluation value information about data amount, evaluation value information about editing contents, and evaluation value information about the number of editors Consists of.

  An example of the evaluation value information regarding the distance is shown in FIG. In the example of FIG. 7A, the evaluation value information regarding the distance is managed as information in which the distance between the users who performed the editing operation and the points are associated with each other. In the example of FIG. 7A, when the distance between the users who performed the editing operation is within 1 km, the point to be assigned is “1”.

  An example of evaluation value information regarding the data amount is shown in FIG. In the example of FIG. 7B, the evaluation value information regarding the data amount is information associating the exchange size indicating the total size of the message data exchanged between a plurality of users and the points when the editing operation is performed. It is managed. In the example of FIG. 7B, when the total size of the message data exchanged between a plurality of users when the editing operation is performed is 10 bytes or less, the point to be given is “1”. .

  An example of the evaluation value information regarding the editing content is shown in FIG. In the example of FIG. 7C, the evaluation value information related to the edited content is managed as information in which the edited content indicating the content of the editing operation is associated with the point. In the example of FIG. 7C, it is indicated that the point to be given is “50” for the editing operation of “photo selection / replacement”.

  An example of evaluation value information regarding the number of editors is shown in FIG. In the example of FIG. 7D, the evaluation value information regarding the number of editors is managed as information in which the number of editors indicating the number of users who have performed the editing operation and points are associated with each other. In the example of FIG. 7D, when the number of editors is one, the point to be given is “100”.

  Note that the evaluation value information illustrated in FIG. 7 is merely an example, and any information may be used as long as the information can be associated with items that can be calculated from the editing history information. In the evaluation value information shown in FIG. 7, the point value may be a fixed value set in advance or manually set by the user.

  For example, the work importance calculation unit 106 calculates the importance with respect to the browsing request when the work acquisition unit 108 described later receives a browsing request from the user via the input / output unit 101. I do. For example, the browsing request information includes information for specifying the importance calculation rule and information about the user who made the browsing request, and the work importance level calculation unit 106 includes a part of the information included in the browsing request information. Alternatively, the importance is calculated using all of them. In this case, the work evaluation apparatus 100 may provide the terminal 109 with information for identifying a user who makes a work browsing request and a user interface for designating importance calculation rules.

  Returning to the description of FIG. 1, the work acquisition unit 108 acquires the work stored in the work information storage unit 103 when receiving a work browsing request from the user via the input / output unit 101. The work acquired at this time is a work evaluated by the work importance calculation unit 106 as having high importance for the accepted browsing request. The acquired work is transmitted to the terminal 109 via the input / output unit 101, for example.

  Next, the importance calculation process by the work evaluation apparatus 100 according to the present embodiment will be described.

  FIG. 8 is a flowchart showing an example of the operation at the time of work acquisition of the work evaluation apparatus 100 according to the present embodiment.

  First, the work evaluation device 100 receives a work browsing request via the input / output unit 101 (S801). The work acquisition unit 108 requests the work importance calculation unit 106 to calculate the importance of the work based on the work browsing request.

  Next, the work importance calculation unit 106 calculates the importance of the work (S802). The works whose importance is to be calculated are, for example, a plurality of works stored in the work information storage unit 103. Further, the importance of the work is performed using, for example, any importance calculation rule included in the reference information shown in FIG. 7 and evaluation value information corresponding to the importance calculation rule shown in FIG. . The importance calculation processing corresponding to the importance calculation rule included in the reference information shown in FIG. 6 will be described later.

  Further, the rule for calculating the importance includes, for example, information specifying the rule in the viewing request information of the work received from the terminal 109, and it may be selected based on this information. As another example, information for specifying a rule is not included in the work browsing request information, and when the work browsing request information is received, it is randomly selected from a plurality of rules stored as reference information. One of the rules may be selected in a predetermined order.

  When the importance level of the work is calculated, the work with the highest importance is specified in response to the work browsing request, and the work acquisition unit 108 is notified.

  Next, the work acquisition unit 108 acquires the work specified in S802 from the work information storage unit 103 (S803). The acquired work is transmitted via the input / output unit 101 to, for example, the terminal 109 owned by the user who has requested to view the work. Moreover, when the work evaluation apparatus 100 is provided with a display part (not shown), it is also conceivable to display the acquired work on the display part.

  Next, the importance calculation processing corresponding to the importance calculation rule included in the reference information shown in FIG. 6 by the work importance calculation unit 106 will be described with reference to FIGS. 9, 10, and 11.

  First, the importance calculation processing when the importance calculation rule is “priority of the number of participants” will be described with reference to the flowchart of FIG. As a premise, a scene is assumed in which N people browse the album page with a certain album ID using the work evaluation apparatus 100 together. It is assumed that the work evaluation device 100 starts calculating the importance from a state where the number N of album viewers is known.

  Here, the number of album viewers can be grasped, for example, by inputting information on the number of album viewers to the work evaluation apparatus 100. In addition to this example, the user ID of the user who browses the album may be input to the work evaluation apparatus 100, and the number of input user IDs may be totaled to obtain the number of album viewers. Furthermore, information for identifying the terminal 109 owned by the user and information for identifying the user are stored in advance in the work evaluation apparatus 100, and when viewing the album, the work evaluation apparatus 100 performs communication by means such as communication with the terminal 109. The user ID corresponding to the terminal identification information acquired can be specified as the user ID of the user browsing the album, and the total number of user IDs specified can be used as the number of participants. .

  First, the importance level calculation rule of “participant number priority” is acquired from the reference information shown in FIG. 6 (S901). For example, as described above, acquisition of the importance calculation rule includes information specifying the importance calculation rule in the work browsing request information, and it is considered that the importance calculation rule is acquired based on this information. In addition, the importance calculation rule may be selected in a predetermined order such as random, rule ID order, and the selected importance calculation rule may be acquired in response to reception of the work browsing request information.

  Next, with reference to the item “number of editors” in the editing history information shown in FIG. 5, it is confirmed whether there is an album page with N editors (S902). If there is no album page with N editors (No in S902), the number of editors is changed to "N-1", which is reduced by one, and the process of S902 is performed again. If there is an album page with N editors (S902: Yes), it is confirmed whether there are a plurality of album pages with N editors (S903).

  If the information of the album viewers can be specified in addition to the number of album viewers, it is determined whether or not there is an album page in which N people including the album viewers participate in editing in the processing of S902 and S902. You may make it confirm. In this case, for example, the “editing number” and the “participant name” may be referred to together in the editing history information shown in FIG.

  When there are not a plurality of album pages with N editors, that is, there is only one album page with N editors (No in S903), the album page has the highest importance and the work is acquired. The highest priority is set (S906). If there are a plurality of album pages with N editors (Yes in S903), points are calculated for each album page using information other than the number of editors (S904). Specifically, for each album page with N participants, the points corresponding to “distance”, “exchange”, and “edit contents” included in the work history information are used in the evaluation value information shown in FIG. And identify these points. At this time, the summation of points may be the sum of the points or the sum of the points multiplied by a predetermined weighting coefficient.

  Next, for the album page where the number of editors is N, a priority order for obtaining works is set (S905). Specifically, the total points of the album pages with N editors are compared, and the priority is set in descending order. Subsequently, it is confirmed whether there is an album page remaining in the album (S907). If there is no remaining album page in the album (No in S907), the importance calculation ends. If there is an album page remaining in the album (Yes in S907), the number of participants is changed to “N-1”, which is reduced by one, and the process proceeds to S902. With the above flow, the priority order of all album pages in the specified album ID is set.

  Next, the importance calculation processing when the importance calculation rule is “point priority” will be described with reference to the flowchart of FIG. As a premise, a scene is assumed in which N people browse the album page of an album ID using the work evaluation apparatus 100 together. The work importance calculator 106 starts calculating the importance from a state in which the number N of album viewers is known. The method for grasping the number of album viewers and participants is as described above.

  First, the importance calculation rule of “point priority” is acquired from the reference information shown in FIG. 6 (S1001). The rule acquisition method at this time is as described above.

  Next, points are calculated for each album page (S1002). Specifically, for each album page, points corresponding to “distance”, “exchange”, “edit contents”, and “number of editors” included in the edit history information shown in FIG. 5 are shown in FIG. The evaluation value information is used for identification, and these points are tabulated. At this time, the summation of points may be the sum of the points or the sum of the points multiplied by a predetermined weighting coefficient.

  Next, priorities are set in descending order of points (S1003). With the above flow, prioritization of all album pages is performed.

  Next, album importance calculation when the importance calculation rule is “individual participant priority” will be described with reference to the flowchart of FIG. As a premise, a scene is assumed in which N people browse the album page of an album ID using the work evaluation apparatus 100 together. The work importance calculator 106 starts calculating the importance from a state in which the number N of album viewers is known. The method for grasping the number of album viewers and participants is as described above.

  First, the importance level calculation rule of “individual participant priority” is acquired from the reference information shown in FIG. 6 (S1101). The rule acquisition method at this time is as described above.

  Next, with reference to the “participant name” in the editing history information shown in FIG. 5, it is determined whether or not there is an album page in which the user who wants to view has participated in the editing (S1102). If there are multiple users who want to browse, one of them may determine whether there is an album page that participates in editing, or all users who want to browse determine whether there is an album page that participates in editing May be.

  If there is no album page in which the user who wants to browse has participated in editing (No in S1102), it is determined that there is no album page whose importance should be calculated according to the importance calculation rule of “individual participant priority”, and processing Exit. If there is an album page in which the user who wants to browse has participated in editing (S1102 is Yes), it is then confirmed whether there are a plurality of such album pages (S1103).

  When there are not a plurality of album pages in which the user who is going to view participates in editing, that is, there is only one album page in which the user who is going to view participates in editing (S1103 is No), the corresponding album page is the most important The degree of priority is high and the priority for obtaining the work is set to be the highest (S1106). When there are a plurality of album pages in which the user who wants to browse participates in editing (S1103: Yes), points are calculated using information other than the participants for each corresponding album page (S1104). Specifically, for each album page on which the user who wants to browse participated in editing, points corresponding to each of “distance”, “exchange”, “edit contents”, and “number of editors” included in the edit history information are displayed. These points are identified by using the evaluation value information shown in FIG. At this time, the summation of points may be the sum of the points or the sum of the points multiplied by a predetermined weighting coefficient.

  Next, for the album page in which the user who wants to browse participates in editing, a priority order for obtaining works is set (S1105). Specifically, the total points of each album page in which the user who wants to browse participates in the editing are compared, and the priority order is set in descending order.

  With the above flow, the priority order of the album pages in which the user who wants to browse participates in editing is set.

  As described above, according to the work evaluation apparatus according to the present embodiment, it is possible to prioritize works based on editing histories by a plurality of persons, for works that are co-created by a plurality of persons. For example, “the display order of album pages when a specified album slide show is played” or “the display order of thumbnail images when listing album pages of a specified album” can be optimally determined. Further, at the time of the slide show reproduction in the above-described example, it is possible not to reproduce and display all the album pages but to reproduce the top several high-priority sheets as a digest.
