Description

  The present invention relates to an information collection control device, an information acquisition device, a service providing system, an information collection control method, and an information acquisition method.

  2. Description of the Related Art Conventionally, there has been proposed a technique for controlling an information collection operation for the purpose of improving information collection efficiency when collecting information on an external target using a plurality of information acquisition devices (see, for example, Non-Patent Document 1). ).

As a technique for improving the efficiency of information collection, for example, continuous information such as the position of a certain object is periodically measured (acquired) using an information acquisition device such as GPS (Global Positioning System). In a system that collects using the wireless band and reproduces the above continuous values by calculation from a part of the collected information, the difference between the true value of the object and the value calculated by the system is a certain threshold value. Techniques aimed at reducing the number of times of information acquisition and information collection in an information acquisition device while maintaining the following have been proposed. In this technique, a model that predicts a future value based on values acquired by the system from the past to the present is used, and a value at the time of next information collection is predicted by the model. Then, the predicted value is compared with the actually obtained value to obtain the divergence between the two. When the divergence is large, the frequency of acquisition and collection is high, and when the divergence is small, the acquisition and collection are performed. By reducing the frequency, the number of times of acquisition and collection is reduced as compared with the case where acquisition and collection are always performed at the maximum possible frequency by the information acquisition apparatus. This aims to achieve the purpose of efficient information acquisition and collection.

  However, the information collection from the information acquisition device, depending on the use of the collected information, does not necessarily reduce the difference between the true value of the measurement target and the value obtained by the calculation as in the above example. There is no need to keep. For example, in a service providing system that determines the operation of each service based on information collected from an external information acquisition device and a plurality of predetermined service execution conditions and collects the determined operation, the information is collected from the information acquisition device. When the importance of this is low (for example, when information having a small influence on the operation of each service execution condition or the number of services to be referred to is small), no problem occurs even when the above-described divergence is large. In such a case, it is not necessary to keep the deviation between the true value of the measurement target and the value obtained by the calculation below a certain value. Therefore, when the importance level is low as described above, information collection and acquisition are not performed, so that information acquisition and service in the information acquisition apparatus can be maintained while keeping the service operation sequence (hereinafter referred to as “service operation”) equal. There was room for further reduction in the number of collections by the providing system (hereinafter referred to as “information collection times”).

  Next, embodiments of the present invention will be described with reference to the drawings. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic.

(Service provision system)
The service providing system according to the present embodiment provides a service at a time when the service execution condition is satisfied based on information collected from one or more information acquisition devices and one or more service execution conditions.

  As shown in FIG. 1, the service providing system according to the present embodiment includes a plurality of information acquisition devices 50 that acquire information, and a server 100 that receives information from the information acquisition device 50. Examples of the information acquisition device 50 include a terminal device having a GPS (Global Positioning System) that acquires position information, a temperature sensor, a humidity sensor, or a site on the Internet where weather forecast information or stock price information is registered. Can be mentioned.

  Further, the information acquisition device 50 and the server 100 communicate via the communication network 30. Examples of the communication network 30 include the Internet, and a LAN, WAN, intranet, or the like may be used.

  The server 100 includes a CPU 101 incorporating an execution condition satisfaction evaluation value deriving unit and an information collection control unit notification condition instruction unit, which will be described in detail later, an input unit 102, an output unit 103, a data holding unit 104, and a program holding unit 105.

  The input unit 102 refers to a device such as a keyboard and a mouse. When an input operation is performed from the input unit 102, corresponding key information is transmitted to the processing control device (CPU) 101. The output unit 103 indicates a screen such as a monitor, and a liquid crystal display (LCD), a light emitting diode (LED) panel, an electroluminescence (EL) panel, or the like can be used.

  The data holding unit 104 holds service execution conditions, received data, and data being processed. The data holding unit 104 may use an internal storage device such as a RAM or an external storage device such as a hard disk or a flexible disk.

  The program holding unit 105 is a storage medium that stores a control program for causing the processing control device (CPU) 101 to execute an execution condition satisfaction evaluation value derivation process, an information collection control process, a notification condition instruction process, and the like described in detail later. . Examples of the recording medium include a RAM, a hard disk, a flexible disk, a compact disk, an IC chip, and a cassette tape. According to the recording medium holding such a program, the program can be easily stored, transported, sold, and the like.

  FIG. 2 schematically shows a configuration example of the server 100 and various information acquisition devices 50a, 50b,..., 50n.

  The server 100 includes an information collection control device 10 and a service execution condition storage unit 20.

  The service execution condition storage unit 20 stores a plurality of service execution conditions 21a, 21b,..., 21n (hereinafter collectively referred to as “service execution conditions 21”) written in a format such as a Bayes decision tree. In the following, a case where there are a plurality of service execution conditions 21 will be described. However, there may be only one service execution condition 21. An example of the service execution condition 21 will be described later with reference to FIGS.

  The server 100 refers to information collected by communication with the information acquisition device 50 and executes a service according to the collected information and the service execution condition 21.

  Here, before describing the processing operation of each unit of the information acquisition apparatus 50, a method for determining a service operation in the server 100, which is a premise of the present invention, will be described. Here, it is assumed that the service execution condition 21 is described in the form of a Bayes decision tree. Examples of service execution conditions 21 described by a Bayesian decision tree are shown in FIGS.

  In the following, service operation determination using a Bayesian decision tree will be described taking the service execution condition (1) for the umbrella preparation recommendation service shown in FIG. 3 as an example.

  In this service execution condition (1), a probability relating to whether or not the current weather is rain is inferred using a state whether or not the humidity is high and a state whether or not the weather forecast is rainy. Then, based on the probability obtained by the inference, it is determined whether or not a message for recommending umbrella preparation should be displayed on the user terminal. Such a determination is made periodically without any explicit instruction from the user.

  Each node indicated by an ellipse in FIG. 3A represents a state variable used for determining the operation of the service. For example, a node described as high humidity (H) represents a state variable expressing whether or not the humidity is high, and the state variable takes two values, high (True) and low (False). The arrow between the nodes indicates that the state represented by the parent node (the original node from which the arrow appears) directly affects the state represented by the child node. In the service execution condition (1), the state of whether or not the humidity is high has a direct influence on the state of rain.

  Such an influence between nodes is expressed in the form of a conditional probability table. The conditional probability table is described for each node, and represents a probability distribution of values taken by the state of the node relative to the state of the parent node. For example, in the service execution condition (1), the value that the state of raining (R) takes is affected by the values of its parent nodes H (high humidity) and W (weather forecast is rainy). Each row in the probability table shows the probability that R (rain falls) will be true for each set of values taken by H (high humidity) and W (weather forecast is rain) (P (R | H, W)) Represents. For example, for a pair where H (high humidity) is True and W (weather forecast is rain) is True, the probability (P (R | H, W)) that R (rains) is True is 0.95. It is expressed.

  On the other hand, a predetermined probability (prior probability) is given to a node that does not have a parent (that is, a node that does not have an incoming arrow). For example, in the service execution condition (1), the probability of high humidity P (H) = 0.2 is expressed.

  By using the conditional probability table and the value of the prior probability, it is possible to calculate probabilities that other states can take when evidence for some states is obtained. For example, the probability of raining and the probability of not falling (P (R | H)) can be calculated when evidence is given for a condition of high humidity (H = True). Such a probability can be obtained from a value inside the Bayesian decision tree by a known calculation algorithm.

  A rectangle in the service execution condition represents a decision-making option in the decision tree. The rectangle (that is, operation (A)) in the service execution condition (1) indicates two operations that are recommended to carry an umbrella (a1) and do nothing (a2). Moreover, the rhombus in the service execution condition indicates the utility value in the state after the actual operation to be performed is determined. The utility value here is expressed in a table format as shown in FIG. 3B, and each row is the selected action and the value of the state variable that affects the utility at that time (the value of the state variable of the parent node of the utility). The utility value for each set is shown.

In service operation judgment using a Bayesian decision tree, the utility expected when EU inputs each node's evidence using currently available information and performs each operation with that evidence obtained (EU) Calculate Then, the operation having the largest utility (EU) obtained by the calculation is executed. For example, in the service execution condition (1), the expected utility before the information is obtained is obtained using the following equation (1).

  Here, ri represents each possible value of the state variable that rains. The expected utility of the action (a1) that recommends taking out an umbrella and the action (a2) that does nothing is calculated as follows.

EU (a1) = 0.2134 × 10 + 0.7866 × 6 = 6.8536
EU (a2) = 0.2134 × (-7) + 0.7866 × 9 = 5.5856
“0.2134” here is a group in which H (high humidity) is True and W (weather forecast is rain) is True, a group in which H is True and W is False, a group in which H is False and W is True, and It is obtained by the sum of the probabilities that R (raining) is true for each pair of H = False and W = False. That is, 0.2 × 0.1 × 0.95 + 0.2 × 0.9 × 0.6 + 0.8 × 0.1 × 0.9 + 0.8 × 0.9 × 0.02 = 0.2134. On the other hand, “0.7866” is obtained as 1−0.2134.

  In the above case, the expected utility EU (a1) of the action (a1) that recommends taking out the umbrella is larger than the expected utility EU (a2) of the action (a2) that does nothing, so the action that recommends taking out the umbrella I do. As such an operation, for example, information (such as a message recommending to take out an umbrella) is transmitted to the terminal device to perform screen display, voice notification, or the like. Along with this, a transmission unit for transmitting information to the terminal device is required in the server 100.

  The service described by each service execution condition obtains evidence regarding some nodes of the service execution condition from the information acquisition device 50. For example, the information acquisition device 50 used in the service execution condition (1) is a humidity sensor included in the user terminal and a weather forecast site on the Internet.

  Another example is the automatic manner mode service shown in FIG. In this service execution condition (2), the probability regarding whether or not the user is in a meeting is inferred using the state whether or not the user is in the conference room and the state whether or not the conference is reserved. Then, based on the probability obtained by inference, it is determined whether or not the user terminal should be set to the manner mode. The service described by each service execution condition obtains evidence regarding some nodes of the service execution condition from the information acquisition device 50. For example, the information acquisition device 50 used in the service execution condition (2) is an in-house system having reservation information and an indoor position measurement device.

  Furthermore, as another example, there is a service end notification service shown in FIG. In this service execution condition (3), the probability regarding whether or not the user leaves the seat and is dealing with the business is inferred using the state of whether or not he / she is at his / her own seat. Then, based on the probability obtained by the inference, it is determined whether or not the desired user should be notified of the end of the business (the user has returned to his / her seat). The service described by each service execution condition obtains evidence regarding some nodes of the service execution condition from the information acquisition device 50. For example, the information acquisition device 50 used in the service execution condition (3) is an indoor position measurement device.

  Subsequently, the operation of each unit of the information collection control device 10 will be described in more detail.

  The information collection control device 10 includes an execution condition satisfaction evaluation value deriving unit 11 (corresponding to the execution condition satisfaction evaluation value deriving unit according to the present invention), an information collection control unit 12 (corresponding to the information collection control unit according to the present invention), and A notification condition instruction unit 13 (corresponding to notification condition instruction means according to the present invention) is provided.

  The execution condition satisfaction evaluation value deriving unit 11 collects information from each information acquisition device 50a, 50b,..., 50n in each service used in the service execution condition, and the service execution condition is satisfied by the collected information. An execution condition satisfaction evaluation value is derived based on the probability. This is realized by, for example, a method in which, for each service execution condition, a probability that the service execution condition is satisfied is given in advance with respect to time, and the probability is set as an execution condition satisfaction evaluation value. Hereinafter, the operation for the service example (1) will be described as an example.

  When information is acquired from the humidity sensor used by the service and the weather forecast site on the Internet, the probability that the information acquisition device service execution condition will be satisfied is 0 am to 8 am, 8 am to 8 pm Is assumed to be 0.6 and from 8 pm to 12:00 pm is 0.4, and the time for obtaining the execution condition satisfaction evaluation value is 3 pm. In this case, the execution condition satisfaction evaluation values of the humidity sensor and the weather forecast site on the Internet are both 0.6.

  Next, the information collection control unit 12 will be described. Based on the evaluation value input from the execution condition satisfaction evaluation value deriving unit 11, the information collection control unit 12 instructs the information collection control device to collect information with a high probability that the service execution condition is satisfied. decide. Then, an information collection instruction is transmitted to the information collection control device at the time. This is realized by setting a threshold value in advance, and setting the time when the threshold value is exceeded to the nearest time in the future as the time for instructing notification.

  As an example, the operation in service example (1) is shown. The set threshold is set to 0.5, and the current time is set to midnight. Execution condition satisfaction evaluation values for both the humidity sensor and the weather forecast site are 0 for 0am to 8am, 0.6 for 8am to 8pm, and 0.4 for 8pm to 12pm, as in the above example. And given. At this time, since the time when the execution condition evaluation value exceeds the threshold value for the first time in the future time is 8:00 am, the information collection control unit 12 transmits information collection instructions to both information acquisition devices at 8:00 am .

  Next, the notification condition instruction unit 13 will be described. The notification condition instructing unit 13 refers to the content of the service execution condition, determines a notification condition (value range) regarding information based on the possibility of satisfying the service execution condition, and transmits the notification condition to the information acquisition apparatus. . The range of this value is set such that the probability that the service execution condition is satisfied is high when the information obtained from the instructed information acquisition apparatus is within the range.

  As an example, the operation in service example (1) is shown. In service example (1), information is collected from the two information acquisition devices of the humidity sensor and the weather forecast site, and it is determined whether or not the service execution condition is satisfied. The humidity sensor has a high probability that the service execution condition will be satisfied if the value obtained from it is “high” (H = True), and the weather forecast site will provide service if the value obtained from it is “rain” (W = True). The probability that the execution condition is satisfied is high. Therefore, when the acquired value obtained for the humidity sensor is “high”, the notification condition instructing unit 13 instructs the weather forecast site that the acquired value is “rain” as the notification condition.

  Next, the information acquisition device 50 will be described. The information acquisition device 50 includes a collection instruction receiving unit 51 (corresponding to the collection instruction receiving unit according to the present invention), a notification unit 52 (corresponding to the notification unit according to the present invention), and a condition receiving unit 53 (receiving the collection condition according to the present invention). A notification condition determination unit 54 (corresponding to a notification condition determination unit according to the present invention).

  The collection instruction receiving unit 51 receives an information collection instruction from the information collection control device and instructs the notification unit 52 to notify the information.

  The notification unit 52 transmits the information acquired by the information acquisition device 50 to the information collection control device 10 in accordance with the information notification instruction input from the collection instruction reception unit 51 and the notification condition determination unit 54.

  The condition receiving unit 53 receives the notification condition instructed from the notification condition instructing unit 13 of the information collection control device 10 and outputs it to the notification condition determining unit 54.

  The notification condition determination unit 54 determines whether the information acquired by the information acquisition device 50 satisfies the notification condition received by the condition reception unit 53. If the notification condition is satisfied, the notification condition determination unit 54 collects information to the notification unit 52. Instructs notification to the control device.

  The notification condition determination unit 54 in the humidity sensor for acquiring the humidity in the service example (1) will be described as an example. It is assumed that the notification condition instructed from the information collection control device 10 is that the value acquired by the sensor is “high”. The notification condition determination unit 54 always monitors whether the acquired value by the sensor is other than “high”, and when the value becomes “high”, the notification unit 52 indicates that the acquired value has exceeded the notification condition. To inform. The notification unit 52 notifies the information collection control device 10 of information according to this instruction.

(Service provision method)
Next, a service providing method according to the present embodiment will be described with reference to FIGS.

  First, the information instruction operation from the information collection control device 10 to the information acquisition device 50 will be described with reference to FIG.

  First, the execution condition satisfaction evaluation value deriving unit 11 derives an execution condition satisfaction evaluation value when information is obtained at each future time point for each information acquisition device used by each service to determine the service execution condition. (S101).

  Next, the information collection control unit 12 determines the next information collection time from each information acquisition device based on the execution condition satisfaction evaluation value (S102). This is realized by setting a threshold value in advance, and setting the time when the threshold value is exceeded to the nearest time in the future as the time for instructing notification.

  Subsequently, the information collection control unit 12 instructs each information acquisition device 50 to notify the information at the determined information collection time (S103). After instructing the information notification, the procedure returns to the procedure for obtaining the execution condition satisfaction evaluation value at the future time again in order to determine the next information notification time.

  Next, a notification condition instruction operation from the information collection control device 10 to the information acquisition device 50 will be described with reference to FIG.

  The notification condition instructing unit 13 acquires a service execution condition (S201). Then, for each information acquisition device, a condition (notification condition) that gives a high probability that the service execution condition is satisfied is obtained (S202). Subsequently, the notification condition instructing unit 13 instructs the information acquisition apparatus 50 on the notification condition (S203).

  Finally, the information notification operation from the information acquisition device 50 to the information collection control device 10 will be described with reference to FIG.

  First, the condition receiving unit 53 receives a notification condition from the information collection control device 10 (S301). Subsequently, the notification condition determination unit 54 acquires a value (information) from the information acquisition device 50 (S302), and whether or not the value (information) acquired by the information acquisition device 50 satisfies the received notification condition. Is determined (S303).

If the acquired value does not satisfy the notification condition, it waits until the next time the value is acquired. When the acquired value satisfies the notification condition, the notification condition determination unit 54 notifies the notification unit 52 of the fact, and the notification unit notifies the information collection control device 10 of the obtained value (S304).

While maintaining, it is possible to reduce the number of times information is collected and the number of times information is acquired by the information acquisition apparatus.

  Further, each information acquisition device determines whether or not the service execution condition has a high probability to be satisfied without notifying the information collection control device, thereby reducing the number of information notifications and the number of information acquisitions. It is possible to keep the operation of the service more correct than before.
