Description

  The present invention relates to a recipient's read / unread determination method in a message transmission / reception system, a transmission / reception apparatus having means for executing the same, and a program for causing a computer to execute the read / unread determination method.

  Information transmission in a message transmission / reception system via the Internet is used when a plurality of people work together. In such a system, it is common for the sender to confirm that the recipient has received the message and to end a series of communications. A system has been proposed in which a sender can confirm whether or not a message has been viewed by a receiver without directly contacting the receiver through other communication means. reference).

  The message sender confirms that the receiver has read the message content, and can safely finish the communication in the message transmission / reception system. On the other hand, a situation may occur in which the recipient only accesses the message and does not read the content of the message. In such a case, in the conventional system, although the receiver has not read the message content, the sender thinks that the receiver has read the message.

  It is an object of the present invention to provide a determination method that determines that a message has been read when it is considered that the message has been read, rather than determining whether the message has been read or not. Moreover, it aims at providing the transmission / reception apparatus provided with the means to perform the determination method.

It is a figure which shows the flow of a process of each component in the message transmission / reception of a message transmission / reception system. It is a figure which shows the flow of a process of each component in the proxy transmission completion notification transmission / reception of a message transmission / reception system.

  This embodiment predicts the time when the receiver finishes reading the message (reading time), and compares the read time with the time when the message is considered to be read (deemed browsing time). This is a method of determining unread. The reading completion time is predicted from the time taken for the receiver to read one character (unit reading completion time) and the number of characters of the message (message size). The deemed browsing time is calculated from the time when the operation of the recipient's message is acquired and the message is considered to be read.

  A unit reading completion time is estimated from a past log data, and a model is predicted. An autoregressive (AR) model is used for this prediction. The prediction time is predicted by multiplying the predicted unit reading time and the message size of the received message, but an error occurs in the predicted value. Considering this error, a prediction error, which is a value for predicting an error between the actually measured value and the predicted value, is calculated, and the reading completion time is given a width depending on the value. The reading time having this width is called a reading time prediction area.

  The deemed browsing time is calculated from the time elapsed in the state defined by the operation on the recipient's message.

  The reading time of the receiver is determined by sequentially comparing the above-mentioned reading time, which is regarded as the reading completion time prediction area.

  There are two cases when it is determined as read by the read determination method. The first is when the message is deleted and the browsing time is within the reading time prediction area, and the second is when the deemed browsing time exceeds the upper limit of the reading time prediction area.

  According to the above-mentioned read determination method, it is possible to determine the completion of the message of the message recipient with a high probability. By using this method, the message is already read when the sender has finished reading the message. A system that can confirm this can be realized.

  Hereinafter, this embodiment will be specifically described.

  FIG. 1 is a diagram showing a flow of preparation for a read determination method according to the present embodiment. Preparation for the already-read determination method consists of two phases. In Phase 1, preparation for calculating the reading completion time prediction area is made, and in Phase 2, preparation for already-read determination is made. T in the figure is a parameter representing a message in time series.

  In Phase 1 of FIG. 1, the unit reading completion time is calculated from the reading completion time sample (S01) collected by some method (S02) and used as the unit reading completion sample (S03). First, an AR model for predicting the unit reading completion time is estimated from the sample of S03 (S04). Thereafter, a prediction error, which is a value that determines the width of the reading completion time prediction area, is calculated (S05). This completes the preparation for calculating the reading completion time prediction area. Phase 1 is performed before using the read determination method.

  Phase 2 in FIG. 2 is performed after the message is received. The unit reading time is predicted from the model estimated in S04 of Phase 1, and the reading time prediction area is calculated from the prediction error calculated in S05 and the message size of the received message (S06). In the read time prediction area, a prediction error is subtracted from the predicted unit read time, the value multiplied by the message size is set as the lower limit, the prediction error is added to the predicted unit read time, and the value multiplied by the message size is set as the upper limit. When the reading completion time prediction area is calculated, the preparation for the already-read determination is finished.

  FIG. 2 is a diagram showing the flow of the read determination in the read determination method according to the present embodiment. The already-read determination is started after completing the preparation phase Phase1 and Phase2.

  In the already-read determination, first, the receiver's operation on the message is acquired, and the current receiver state is determined (S07). At this time, the state is defined by three operations as shown in the balloon for S07 in FIG. The state from when the receiver focuses to the message until the focus is removed a) the state that the message is read, and the time that the message is removed after the focus is removed b) the state that only the message is displayed And

  The browsing time is calculated from the above-described a) and b) time elapsed in each state (S08). At this time, in a) and b), since it is not certain whether b) is reading a message, the elapsed time is weighted. This weight is the ratio of the time elapsed in the state a) to the total time elapsed in the state a) and the state b) for all messages received in the past.

  The deemed browsing time calculated in S08 is compared with the reading completion time prediction area calculated in S06 of Phase 2 (S09), and it is determined whether or not the recipient has read the message (S10). There are two when it is determined as read in S10. The first is when the message is deleted and the browsing time is within the reading time prediction area, and the second is when the deemed browsing time exceeds the upper limit of the reading time prediction area.

  By sequentially executing the read determination in the flow shown in S07 to S10, the read of the receiver can be determined. This determination is performed at an appropriate interval.

  The steps shown in FIGS. 1 and 2 are grasped as means for realizing the respective functions, and are specifically executed by a computer.

  As an example of the already-read determination method according to the present embodiment, it was confirmed whether or not it was correctly determined to be read using data of only the reading time when the message was read and the reading time prediction area. This is a confirmation of whether the setting of the reading completion time prediction area is appropriate.

  The data used for confirmation was collected when 30 messages were transmitted by a message transmission / reception system that adapted the read determination method to nine target persons. The used system is provided with a function of recording a reading time and a reading time prediction area only when each message is read. In addition, the recording was performed from the state in which the preparation of Phase 1 in FIG.

  In the read / unread determination based on the reading completion time prediction area, it can be said that it is a positive determination when there is no reading time and the browsing time is within the reading time prediction area. On the other hand, when there is no reading only when reading is longer or shorter than the reading time prediction area, it is determined that the reading has not been performed although it has already been read. Based on the distance from the estimated reading time to the reading completion time prediction area, it was confirmed whether it was an appropriate reading time prediction area.

  The average value of the reading time prediction area, that is, the absolute value of the difference between the predicted reading time and the reading time without reading (hereinafter referred to as D) is clustered by the K-means method. It is assumed that a value that is larger than the boundary value of the cluster obtained by clustering is an appropriate misjudgment, and a value that is small is an appropriate positive decision.

  It can be said that the read / unread is properly determined by the read time prediction area when the ratio of the correct / incorrect determination by the read time prediction area and the correct / incorrect determination by the cluster boundary value is high.

  Table 1 summarizes the determination results obtained when each message is determined by the two methods described above.

  From Table 1, the ratio of correct / incorrect determination based on the read time prediction area and correct / incorrect determination based on the boundary value of the cluster is 84%.

  With this method, read / unread can be automatically determined with high probability.

  An embodiment of the message transmission / reception system 1000a will be described in which the sender can confirm that the receiver has surely read the message using the above-described read determination method. FIG. 3 is a block diagram of such a message transmission / reception system.

  The outline of the message transmission / reception system 1000a is as follows. The message transmission / reception system 1000a is a system that enables transmission / reception of messages by communication between a server (Server 100) and a client (Client 200) installed in a PC via a network. When a user sends a message, the client 200 is activated, the content of the message is input to the client 200, and the destination is selected and sent. When the message is transmitted, the Server 100 holds the message and transmits the message to the Client 200 that is the message destination. The client 200 of the destination user displays the received message on the screen of the PC, thereby browsing the message content. When the message is determined to be already read by the already-read determination method, the sender is notified of the completion of reading by the receiver. A message notifying the sender of the completion of reading by the receiver is called a proxy reading completion notification.

Hereinafter, each component included in the configuration diagram of the message transmission / reception system 1000a, which is an application example of the present invention, will be described.
