  FIG. 1 is a diagram showing an information processing system 10 according to an embodiment of the present invention. The information processing system 10 includes an information processing apparatus 100, a server 200 connected to the information processing apparatus 100 via a network 400, and a terminal apparatus 300 (300-1, 300-2 connected to the server 200 via a network 500). ,... 300-n). The information processing device 100, the server 200, and the terminal device 300 are information processing devices such as personal computers.

  The information processing apparatus 100 acquires operation information indicating the content of an operation performed on the terminal device 300 (300-1, 300-2,... 300-n), and estimates the number of users who use the terminal device 300. To do.

  The terminal device 300 is a personal computer, a tablet terminal, or the like that is installed in a predetermined range such as in a certain company building or in a certain floor and used by one or more users. The server 200 is a device that is connected to the terminal device 300 and performs communication, and acquires operation information indicating the content of an operation performed on the terminal device 300 (300-1, 300-2,... 300-n). To the information processing apparatus 100.

  The configuration of the information processing apparatus 100 is shown below. FIG. 2 is a block diagram showing a hardware configuration of the information processing apparatus 100 according to an embodiment of the present invention. The information processing apparatus 100 includes an operation unit 102, a display unit 103, a CPU 104, and a storage unit 105 that are connected to each other via a bus 101. The operation unit 102 is a keyboard, a mouse, or the like, and accepts an operation by an operator of the information processing apparatus 100. The display unit 103 is a display device such as a liquid crystal display. The CPU 104 operates by a program stored in the storage unit 105, and realizes each function described later. The storage unit 105 includes a storage element such as a hard disk or a memory.

  The operation of the information processing apparatus 100 will be described below. The information processing apparatus 100 uses a plurality of accounts acquired separately based on the assumption that operations executed at intervals shorter than a short time (predetermined threshold) such as 0.5 seconds are likely to be performed by different users. On the other hand, a process for determining two accounts that have been operated at short intervals as different users is performed, a group of accounts that are finally determined to correspond to the same person is defined, and the number of groups is defined as the number of users. Estimated.

  FIG. 3 is a functional block diagram showing functions of the information processing apparatus 100 according to an embodiment of the present invention. The information processing apparatus 100 includes a communication unit 110, an operation information storage unit 120, a difference acquisition unit 130, a difference determination unit 140, a parameter update unit 150, a parameter holding unit 160, a parameter determination unit 170, a user number estimation unit 180, and attribute estimation. Part 190. The communication unit 110, the difference acquisition unit 130, the difference determination unit 140, the parameter update unit 150, the parameter determination unit 170, the user number estimation unit 180, and the attribute estimation unit 190 are included in the CPU 104 that operates according to a program stored in the storage unit 105. The operation information accumulating unit 120 and the parameter holding unit 160 are realized as functions, and are configured by storage elements such as a hard disk and a memory constituting the storage unit 105.

  The communication unit 110 communicates with the server 200 via the network 400, acquires operation information indicating the content of the operation executed on the one or more terminal devices 300 acquired in the server 200, Output to the operation information storage unit 120. The operation information storage unit 120 stores the operation information acquired by the communication unit 110. FIG. 4 is a diagram illustrating an example of operation information stored in the operation information storage unit 120. The operation information includes the time (timing) when the operation was performed, the account that was logged in when the operation was performed (execution entity information indicating the entity that performed the operation), and processing by multiple devices via the network (remote desktop) Etc.) and information indicating the contents of the operation. FIG. 5 is a diagram representing the operation information on the time axis.

  For the two pieces of operation information including different accounts stored in the operation information storage unit 120, the difference acquisition unit 130 executes the timing for the operation related to one operation information and the operation related to the other operation information. The difference between the timing and the timing is acquired. The difference acquisition unit 130 includes an operation information acquisition unit 131 and a difference calculation unit 132.

  The operation information acquisition unit 131 acquires two pieces of operation information corresponding to different accounts among the operation information stored in the operation information storage unit 120. For example, the operation information acquisition unit 131 selects one piece of operation information (a in FIG. 4), and for each account (AC1, AC3, AC4) different from the account (AC7) included in the operation information, The operation information (b, c, d in FIG. 4) executed at the nearest time is selected. Here, since it is considered that the operation at the connection destination and the connection source is related to the same operation by the same person, one of the operations (for example, only the operation information of the connection destination) is referred to. Then, the operation information acquisition unit 131 acquires a and b and outputs them to the difference calculation unit 132, and then sequentially acquires a and c and a and d, respectively, and outputs them to the difference calculation unit 132. Thus, regarding the operation information related to a, when acquisition and output of two pieces of operation information (a set of operation information) for all the accounts AC1, AC3, and AC4 that are different from the account AC7 of the operation information are completed, operation information different from a is displayed. Select and similarly obtain and output a set of operation information. Thereafter, a set of operation information is obtained and output for all operation information in the same manner.

  The difference calculation unit 132 performs the time at which these operations are performed on the set of operation information input from the operation information acquisition unit 131 based on information indicating the time at which the operation is included in the operation information. The difference is calculated. The calculated difference is output to the difference determination unit 140 together with each account of the set of operation information.

  The difference determination unit 140 compares the difference input from the difference acquisition unit 130 with a predetermined threshold (first threshold), and outputs a determination result and information indicating an account to the parameter update unit 150. Here, a relatively small numerical value (short time) such as 0.5 seconds is set as the predetermined threshold. This is because it is unlikely that two operations performed by different accounts with an interval shorter than this value are due to the same person. The difference determination unit 140 determines whether or not the difference is smaller than this threshold value.

  The parameter update unit 150 updates the parameter held in the parameter holding unit 160 based on the determination result input from the difference determination unit 140 and information indicating the account. FIG. 6 is a diagram illustrating an example of parameters held in the parameter holding unit 160. These parameters indicate the possibility that two corresponding accounts correspond to the same person, and the larger the value, the higher the possibility that the corresponding person is the same person. The parameter is initialized to a predetermined value and held in the parameter holding unit 160. The parameter updating unit 150 updates the parameter corresponding to the account combination determined to have a difference smaller than a predetermined threshold (first threshold) based on the determination result and information indicating the account by a predetermined decrease value. Execute the process. The difference determination unit 140 and the parameter update unit 150 execute a threshold determination process and a parameter update process based on all the differences input from the difference acquisition unit 130.

  The parameter determination unit 170 determines whether or not two arbitrary accounts correspond to the same user based on the parameters stored in the parameter storage unit 160. Parameter determination unit 170 includes a parameter correction unit 171 and a threshold determination unit 172. The parameter correction unit 171 performs correction based on the number of times the threshold determination process and the parameter update process are executed for each of the parameters held in the parameter holding unit 160. For example, when the initial value of the parameter is 0, the parameter correction unit 171 divides each parameter by the number of times the threshold determination process and the parameter update process are executed.

  The threshold value determination unit 172 compares the parameter corrected by the parameter correction unit 171 with a predetermined threshold value (second threshold value). If the threshold value is smaller than the threshold value, it determines that the corresponding two accounts correspond to different users. If it is equal to or greater than the threshold, it is determined that the corresponding two accounts correspond to the same user. That is, the parameter determination unit 170 determines whether or not the combination of two accounts is an account corresponding to the same user based on the difference acquired by the difference acquisition unit 130. The parameter determination unit 170 performs the above processing for all parameters held in the parameter holding unit 160.

  The user number estimation unit 180 estimates the number of users who operate the terminal device 300 based on the determination result by the parameter determination unit 170. The user number estimation unit 180 includes a group generation unit 181 and a user number correction unit 182.

  The group generation unit 181 acquires information indicating all accounts based on the operation information stored in the operation information storage unit 120, and 1 corresponding to the same user based on the determination result by the parameter determination unit 170. Alternatively, a group generation process (clustering process) including a plurality of accounts is executed. FIG. 7 is a diagram illustrating a result of the clustering process performed by the group generation unit 181. In FIG. 7, the accounts connected by the solid line are accounts determined to correspond to the same user. In this example, a user corresponding to the group 701 consisting of AC1 and AC2, a user corresponding to the group 702 consisting of AC3, AC4, and AC6, a user corresponding to the group 703 consisting of AC5, and a user corresponding to the group 704 consisting of AC7, It is considered that there are four users.

  The user number correction unit 182 corrects the number of users estimated based on the number of groups generated by the group generation unit 181. The number-of-users correction unit 182 acquires the number of terminal devices 300 for which operation information is not acquired by, for example, direct input to the information processing apparatus 100. When the number of terminal devices 300 from which operation information is acquired is X and the number of terminal devices 300 from which operation information is not acquired is Y, the user number correction unit 182 sets the number N of users estimated based on the number of groups. On the other hand, the number of users is corrected by calculating N × (X + Y) / X. The number Y of terminal devices 300 from which operation information is not acquired is obtained by, for example, acquiring the number Z of all terminal devices 300 on the target floor, and calculating the difference between Z and the number X of terminal devices 300 from which operation information is actually acquired. It is also acquired by calculating.

  The attribute estimation unit 190 again obtains operation information for each group (user) specified by the group generation unit 181 and estimates the user's attributes based on the operation information. FIG. 8 is a diagram illustrating an example of user attributes specified from the operation information. Information indicating the identified attribute is output to the display unit 103 of the information processing apparatus 100, for example, together with information indicating the estimated number of users.

  Next, operation | movement of the information processing system 10 which concerns on this embodiment is demonstrated using a flowchart. FIG. 9 is a flowchart showing the operation of the information processing system 10 according to an embodiment of the present invention.

  First, for each operation executed on a plurality of terminal devices 300 (300-1, 300-2,... 300-n), the server 200 includes an account (execution entity information) indicating the entity that performed the operation. Operation information including the execution timing information indicating the timing at which the operation is executed is acquired (S901).

  The information processing apparatus 100 receives the plurality of operation information acquired by the server 200 in S901 via the network 400, and the operation information storage unit 120 of the information processing apparatus 100 stores the received plurality of operation information (S902). .

  The parameter holding unit 160 of the information processing apparatus 100 sets, as an initial value, a parameter indicating the possibility of corresponding to the same user for two different combinations of accounts included in each of a plurality of operation information. (S903).

  The difference acquisition unit 130 of the information processing device 100 includes the timing at which the operation related to one operation information is executed and the other operation information for two pieces of operation information including different accounts stored in the operation information storage unit 120. The difference between the timing when the operation is executed and the timing is acquired (S904).

  The difference determination unit 140 of the information processing apparatus 100 performs threshold determination on the difference acquired by the difference acquisition unit 130 (S905), and the parameter update unit 150 uses the parameter determination unit based on the result of the threshold determination in S905. The parameter held in 160 is updated (S906).

  The difference acquisition unit 130 of the information processing apparatus 100 determines whether timing differences have been acquired for all combinations of two pieces of operation information including different accounts stored in the operation information storage unit 120 (S907). If there is a combination for which the difference is not acquired, the process returns to S904.

  If it is determined in S907 that timing differences have been acquired for all combinations, the parameter correction unit 171 of the parameter determination unit 170 corrects the parameters held in the parameter holding unit 160 (S908). The threshold determination unit 172 of the parameter determination unit 170 performs threshold determination for the corrected parameter, and determines that the combination of accounts whose parameters are smaller than the threshold is an account corresponding to a different user (S909). That is, the parameter determination unit 170 determines whether or not the combination of two accounts is an account corresponding to the same user, based on the difference acquired by the difference acquisition unit 130 in S904.

  The group generation unit 181 of the user number estimation unit 180 generates an account group based on the result of the determination process in the parameter determination unit 170 (S910). The user number correction unit 182 of the user number estimation unit 180 acquires the number of terminal devices 300 from which operation information is not acquired, and corrects the number of groups (estimated number of users) generated in S910 (S911). .

  The attribute estimation unit 190 acquires operation information for each group (user) specified by the group generation unit 181 and estimates a user attribute from the content of the operation information (S912).

  Information indicating the number of users estimated by the above processing and the user attributes is output to the display unit 103 of the information processing apparatus 100 (S913). Above, the process in the information processing system 10 which concerns on one Embodiment of this invention is complete | finished.

  According to the above configuration, with respect to an operation executed on the terminal device 300, a plurality of pieces of operation information including an account (execution entity information) indicating an entity that has performed the operation is acquired and included in the acquired operation information. An information processing system 10 is provided that performs a determination process for determining two or more accounts as accounts corresponding to different users.

  In addition, this invention includes the structure changed in the range which does not deviate from the meaning of the said embodiment, and is not limited to the said embodiment.

  For example, in the above-described embodiment, the process for determining based on the difference (time difference) between the execution times of operations corresponding to different accounts is shown. However, the determination may be based on the execution time of each operation. Other configurations may be used. For example, the difference acquisition unit 130 corresponds to operation information at the end of a plurality of continuous operation information corresponding to an account (first account) and an account (second account) different from the first account. The parameter update unit 150 obtains a difference with respect to the head operation information of a plurality of consecutive operation information, and the parameter update unit 150 increases a corresponding parameter by a predetermined value when the difference is smaller than a predetermined threshold value. Good. This is because, when the above-described difference is small, it is estimated that the same user is operating by changing from one account (first account) to another account (second account).

  In the above embodiment, the information processing system 10 that uses an account as execution subject information has been disclosed. However, other information may be used as long as the information indicates an operation attribute indicated in the operation information. It may be configured to use the device ID of the terminal device 300 that has been operated, the location information of the area where the operation is performed, the building, the floor, the room, the seat, the attribute of the operation target (data), and the like.

  The operations of the information processing apparatus 100, the server 200, the terminal apparatus 300, and the like described here are realized by operating programs stored in the respective storage units. This program may be provided by communication, or may be provided by being stored in a storage medium such as a CD-ROM that can be read by a computer.
