In the example of Fig. 1, for simplification, one client device 110 is shown as the client device 110 included in the information processing system 1000, but multiple client devices 110 may be included.

[0012] 2. Hardware Configuration (1) Hardware Configuration of Server Device 100 FIG. 2 is a diagram showing an example of a hardware configuration of the server device 100. The server device 100 includes, as a hardware configuration, a control unit 201, a storage unit 202, and a communication unit 203. The control unit 201 is, for example, a central processing unit (CPU) or the like, and controls the entire server device 100. The storage unit 202 is, for example, a read only memory (ROM), a random access memory (RAM), a hard disk drive (HDD), a solid state drive (SSD), or a combination thereof, and stores a program and data used when the control unit 201 executes a process based on the program. The control unit 201 executes a process based on the program stored in the storage unit 202, thereby realizing functions of the server device 100. The communication unit 203 connects the server device 100 to the network 150 and manages communication with external devices.

[0013] (2) Hardware Configuration of the Client Device 110 FIG. 3 is a diagram showing an example of the hardware configuration of the client device 110. The client device 110 includes, as the hardware configuration, a control unit 301, a storage unit 302, an imaging unit 303, an input display unit 304, a communication unit 305, an audio input unit 306, and an audio output unit 307. The control unit 301 is, for example, a CPU or the like, and controls the entire client device 110. The storage unit 302 is, for example, a ROM, a RAM, a HDD, an SSD, or a combination thereof, and stores a program and data used when the control unit 301 executes processing based on the program. The control unit 301 executes processing based on the program stored in the storage unit 302, thereby realizing the functional configuration of the client device 110 shown in FIG. 4 and the processing of the activity diagram shown in FIG. 5, which will be described later. The imaging unit 303 captures an image of a subject. The subject is, for example, an operator of the client device 110. The input display unit 304 is, for example, a touch panel, and transmits input information to the control unit 301 based on an input operation, and displays the results of information processing by the control unit 301. That is, the control unit 301 accepts a selection operation by the user via the input display unit 304.

The audio input unit 306 is, for example, a microphone, and inputs the user's voice. The audio output unit 307 is, for example, a speaker, and outputs the voice. The storage unit 302 is an example of a storage medium.

[0014] 3. Functional configuration 4 is a diagram showing an example of the functional configuration of the client device 110. The client device 110 includes a setting unit 401, a determination unit 402, and a display control unit 403 as its functional configuration. The setting unit 401 sets a starting point of a user's action. For example, the setting unit 401 sets a starting point of a user's action based on a user operation via the input display unit 304. The determination unit 402 determines the attractiveness of each spot. Here, a spot is a specific place, location, facility, etc. In this embodiment, the spot is associated with news provided by the server device 100 or another server device that can communicate with the server device 100. The display control unit 403 displays on the input display unit 304 the screens shown in FIGS.

[0015] 4. Information Processing FIG. 5 is an activity diagram showing an example of information processing by the client device 110. As shown in FIG. In A601, the setting unit 401 determines whether or not a starting point of the user's action has been selected. For example, when the user selects a position on a map included in the screen displayed on the input display unit 304 of the client device 110, it determines that the starting point of the user's action has been selected. When the setting unit 401 determines that the starting point of the user's action has been selected, it advances the process to A602. When the setting unit 401 determines that the starting point of the user's action has been selected, it repeats the process of A601.

[0016] In A602, the setting unit 401 sets a starting point of the user's action. In A603, the determination unit 402 determines the attractiveness of each spot. In A604, the display control unit 403 controls the input display unit 304 of the client device 110 to display a screen including multiple candidates for spots to which the user will head from the starting point set in A602. Here, the server device 100 generates the screen and transmits it to the client device 110. The client device 110 may then display the screen received from the server device 100. The server device 100 may also transmit data for generating the screen to the client device 110. The client device 110 may then generate and display the screen based on the data received from the server device 100. The same applies hereinafter regarding the display of the screen.

[0017] FIG. 6 is a diagram (part 1) showing an example of a screen displayed on the input display unit 304 of the client device 110. In the screen shown in FIG. 6, the starting point 610 is a mark indicating the starting point set by the user. Spot candidates 620-650 are recommended spot candidates to which the user will next go from the starting point 610. News is associated with the spot candidates. The multiple spot candidates included in the screen are arranged on the screen in order of recommendation degree. In the example of FIG. 6, the recommendation degree is highest in the upper left, and decreases in the order of the upper right, lower left, and lower right. The same applies to the following screens. Here, the recommendation degree is determined by the display control unit 403 based on the position information of the starting point set by the setting unit 401, the position information of the multiple spots, and the attractiveness of each spot determined by the determination unit 402. As shown in FIG. 6, the screen also includes map information.

[0018] In A605, the display control unit 403 determines whether or not a spot has been selected on a screen such as that shown in FIG. 6. For example, when the user selects one of the spot candidates 620 to 650 on the screen and presses and holds the spot, the display control unit 403 determines that the spot has been selected. The operation of the user selecting one of the spot candidates 620 to 650 on the screen and pressing and holding the spot is an example of an operation of the user selecting one of the multiple spot candidates. When the display control unit 403 determines that the spot has been selected, the process proceeds to A606. When the display control unit 403 determines that the spot has not been selected, the process proceeds to A607. In A606, the display control unit 403 controls the input display unit 304 of the client device 110 to display a screen including a plurality of candidates for spots to which the user should next go from among the selected candidate spots.

[0019] FIG. 7 is a diagram (part 2) showing an example of a screen displayed on the input display unit 304 of the client device 110. In the screen shown in FIG. 7, the selected spot 710 is a spot candidate selected by the user in FIG. 6. Spot candidates 720 to 750 are recommended spot candidates to which the user will next go from the selected spot 710. News is associated with the spot candidates. The multiple spot candidates included in the screen are arranged on the screen in order of recommendation degree. The recommendation degree is determined by the display control unit 403 based on the location information of the selected spot candidate, the location information of the multiple spots, and the attractiveness of each spot determined by the determination unit 402. To explain more specifically using FIG. 7, the display control unit 403 determines the recommendation degree based on the location information of the selected spot 710, which is a candidate for the selected spot, the location information of the multiple spots, the attractiveness of each spot determined by the determination unit 402, and the stop information of the transportation mobile body related to the location information of the starting point. Here, the stop information of the transportation mobile body is the location information of a train station located near the starting point. The stop information of the transport vehicle may be the position information of a bus stop other than the train stop, and may be the position information of a nearby station on the same line as the train station located near the starting point other than the position information of a train station located near the starting point. The screen shown in FIG. 7 also includes map information.

[0020] In A607, the display control unit 403 judges whether or not to end the display of the screen as shown in FIG. 7. When the display control unit 403 judges that the display of the screen as shown in FIG. 7 is to be ended, the display control unit 403 ends the information processing shown in FIG. 5. When the display control unit 403 judges that the display of the screen as shown in FIG. 7 is not to be ended, the processing returns to A605. Each time the user performs an operation to select one of the multiple spot candidates, the display control unit 403 executes the processing shown in A606. For example, when the user selects one of the spot candidates 720-750 on the screen shown in FIG. 7 and presses and holds it, the display control unit 403 controls the input display unit 304 of the client device 110 to display a screen including multiple spot candidates to which the user will next go from the selected spot candidate.

[0021] Fig. 8 is a diagram (part 3) showing an example of a screen displayed on input / display unit 304 of client device 110. In the screen shown in Fig. 8, selected spot 810 is the spot candidate selected by the user in Fig. 7. Spot candidates 820 to 850 are recommended spot candidates to which the user should next go after selected spot 810.

[0022] Here, when a route is selected, the display control unit 403 controls so that a route that sequentially connects the selected spots selected by the user from the starting point 610 is displayed on the input display unit 304 of the client device 110. FIG. 9 is a diagram (part 4) showing an example of a screen displayed on the input display unit 304 of the client device 110. 910 shown in FIG. 9 is an example of a route that sequentially connects the selected spots selected by the user from the starting point 610. As shown in FIG. 9, the display control unit 403 determines the recommendation level so that the last spot of the route is a train station close to the starting point. More specifically, the display control unit 403 determines so that the last spot of the route at the selected time is a train station close to the starting point.

[0023] Here, for example, when the user taps and selects one of the spot candidates on the screen, the display control unit 403 controls so that a screen including news related to the selected spot candidate is displayed on the input display unit 304 of the client device 110. The operation of tapping and selecting one of the multiple spot candidates is an example of an operation of the user reading news related to the spot.

[0024] As described above, according to the process of this embodiment, it is possible to sequentially present a plurality of suitable candidates for a user going from one location to another.

[0025] (Variation 1) A modification of the first embodiment will be described. The information processing system 1000 of the first modification stores selection history information regarding spots previously selected by the user. In addition, the display control unit 403 of the first variant determines the recommendation level based on the location information of the selected candidate spot, the location information of multiple spots, the attractiveness of each spot determined by the determination unit 402, and the selection history information. According to the first modification, the recommendation level can be determined based on the attributes of spots previously selected by the user.

[0026] (Variation 2) A modification of the first embodiment will be described. The determination unit 402 in the second modification changes the attractiveness of each spot based on the weather. For example, the determination unit 402 changes the attractiveness of an outdoor spot to be higher than that of an indoor spot when the weather is good, and changes the attractiveness of the outdoor spot to be lower than that of an indoor spot when the weather is bad. Furthermore, the determination unit 402 may change the attractiveness of each spot based on whether the spot is new or not. For example, the determination unit 402 may change the attractiveness of a newer spot so that the newer the spot is, the higher the attractiveness of the spot is. Furthermore, the determination unit 402 may change the attractiveness of each spot based on whether or not an event is being held. For example, the determination unit 402 may change the attractiveness of a spot where an event is being held to be higher than the attractiveness of a spot where no event is being held. Furthermore, the determination unit 402 may change the attractiveness of each spot based on whether it is associated with news. For example, the determination unit 402 may change the attractiveness of a spot associated with news to be higher than the attractiveness of a spot not associated with news. Furthermore, the determination unit 402 may change the attractiveness of a spot to be higher the more news the spot is associated with. According to the second modification, the attractiveness of a spot can be changed depending on the weather, whether it is a new spot, whether an event is being held, whether it is related to news, and the like.

[0027] (Variation 3) A modification of the first embodiment will be described. Fig. 10 is a diagram showing an example of selection history information. The selection history information is stored for each user in the information processing system 1000. As shown in Fig. 10, the selection history information includes a log of a selection behavior, which is a log of a certain state and the next state. The category transition probability matrix is ​​obtained by dividing each row of the log in Figure 10 by the sum of the rows. uμ Let us assume that.

[0028] First, the mathematical notation is presented. i, j, k: indexes corresponding to spots t: Subscript indicating the area's central station (considered a type of spot) u,μ: Subscripts corresponding to categories. “Not selected” in Figure 10 is also considered as one category. (Let spot i belong to category u and spot j belong to category μ.) S: A collection of spots Su: A set of spots that belong to category u, i.e. a subset of S C: A collection of categories h: hop count index 0 is the initial state, h+=1 thereafter p ij (h): Probability of transitioning to j when at spot i after hop count h (= recommendation index) p 散 ij : Probability of moving to j when in spot i in the wandering force p 駅 ij : Probability of transitioning to j when at spot i in a strategy to return to the station q uμ : Category transition probability obtained from the aggregation of Figure 10 c ij : The cost of travel from spot i to spot j (the cost is either distance or time, or both) A j : Attractiveness of spot j Maximum value 1 Weather dummies and gender dummies are taken into account here. γ: Distance resistance coefficient W ij : Magic weight defined between each spot I and j (matrix is ​​W) f ij :Matrix element for calculating magic weight (matrix is ​​F)

[0029] In the third modification, W ij We use the magic weight denoted by Each element is f ij =exp[-γc ij ]A j Prepare a matrix F with |S|?|S| given by:

number

[0030] At this time, the magic weight W ij The matrix W, whose elements are as follows, can be calculated using the following matrix calculation:

number

[0031] In the "return to station strategy," the station refers to the central station of the area. Stations are also considered as spots, and the spot index is t. ·To prevent re-starts from the station, all c ti = infinity

[0032] Attractiveness level A j It is preferable to use it as a flag variable. The main use is to use weather dummies and gender dummies as 0,1 variables. A by the number of likes on the site j It is possible to weight the A j Set the maximum value to 1. j If A is excessively large, the condition that the "maximum absolute value of the eigenvalue" is less than 1 will no longer be satisfied, and W will not be calculated properly. j The maximum value is 1, and 0 < A j < A gradation is applied within the range of 1. Therefore, it is possible to assign weights of 1 for spots related to news, 0.1 for facility information only, and so on.

[0033] Strategy for walking 散 ij and a p to get him back to the station 駅 ij Calculate both p 駅 ijThe magic weights are used to calculate p 駅 ij The calculation formula is as follows:

number

[0034] Magic Weight

number

[0035] To briefly explain (3), the denominator is: W it Degree of freedom to arrive at station t from spot i via various routes And the molecule is exp[-γc ij ]A j Moving from spot i to spot j, W jt After that, the degree of freedom to reach station t from spot j via various routes Therefore, the higher the degree of freedom, the higher the transition probability.

[0036] This transition probability p 駅 ij If you hop from spot to spot along the line, you will eventually reach the station via a "nice route". In other words, when you are at spot i (if you want to return to the station), the next spot recommendation is p 駅 ij This is the transition probability = recommendation calculation method when returning to the station without considering the category transition matrix.

[0037] Next, we will explain how to calculate the transition probability for the strolling strategy. In conclusion, we can simply scatter the area set at the station in (3), so

number

[0038] Next, we consider changing the strategy depending on the number of hops. In other words, it seems good to let the robot wander freely for the first one or two hops, and then gradually change the strategy to guide the robot to the station. The above p 散 ij andp 駅 ij If both of these can be calculated, this can be easily achieved by blending appropriately according to the number of hops h. For example,

number

[0039] Let us summarize the transition probability of the strategy of returning to the station. First, given that a certain category μ has been selected, the transition probability to spot j in that category μ is

number

[0040] In order to make recommendations consistent with the category transition matrix obtained from the aggregation in Figure 10,

number

[0041] The transition probability for the wandering strategy is calculated as follows:

number

[0042] Finally, depending on the number of hops, the strategy changes as follows:
