Based on the group chat information stored in the group chat information storage unit 32, the determination unit 41 determines whether two or more users U plan to act together. Specifically, the determination unit 41 determines whether or not two or more users U plan to act together based on group chat messages from two or more users U among the plurality of users U participating in the group chat. do. In the following, there are cases where two or more users U acting together is described as an event, and a schedule in which two or more users U act together is described as an event schedule.

The determination unit 41 has, for example, a learned event proposal determination model generated by learning based on a data set including group chat messages and labels indicating whether or not an event is proposed. The determination unit 41 inputs a group chat message to the event proposal determination model, and determines that the group chat message includes an event proposal when the score output from the event proposal determination model is equal to or greater than a threshold. do.

For example, the determination unit 41 determines the users U who participate in the proposed event based on the group chat messages of the users U after the event is proposed. For example, the determination unit 41 has a learned event participation determination model generated by learning based on a data set including user U's group chat messages and labels indicating whether or not to participate in the proposed event. .

The determination unit 41 inputs a group chat message to the event participation determination model, and selects the user U who has sent the group chat message whose score output from the event participation determination model is equal to or greater than a threshold to participate in the proposed event. User U is determined.

Further, the determination unit 41 determines the meeting time of the users U participating in the event at the meeting place based on the message determined to include the event proposal or the group chat message of the user U who proposed the event. determines the waiting time.

For example, the determination unit 41 has a learned meeting date/time determination model generated by learning based on a data set including user U's group chat and labels indicating meeting dates/times. The determination unit 41 inputs a group chat message to the meeting date/time determination model, and determines the meeting time from a character string included in a message output from the meeting date/time determination model whose score is equal to or greater than a threshold.

Also, the determination unit 41 determines a user U who once expressed participation in the proposed event but later expressed non-participation based on the group chat message of the user U after the event was proposed.

For example, the determination unit 41 determines the learned event non-participation generated by learning based on the data set including the group chat message of the user U who expressed participation in the event and the label indicating whether or not to participate in the proposed event. It has a judgment model. The determination unit 41 inputs a group chat message to the event non-participation determination model, and requests a user U who has sent a group chat message whose score output from the event non-participation determination model is equal to or greater than a threshold value to participate in the proposed event. It is judged as the user U who expressed non-participation after the declaration.

Note that each of the event proposal determination model, the event participation determination model, the meeting date and time determination model, and the event non-participation determination model is, for example, a model using a neural network, but is not limited to such an example. For example, each of the event proposal determination model, the event participation determination model, the meeting date and time determination model, and the event non-participation determination model is generated by various learning processes (machine learning) such as linear regression, logistic regression, or support vector machines. It can be a model.

Further, for example, the determination unit 41 divides the message of the group chat into a plurality of morphemes by morphological analysis, and analyzes the character strings of specific parts of speech such as nouns and verbs included in the plurality of divided morphemes. The configuration may be such that the determination is performed. For example, by analyzing a character string of a specific part of speech, the determination unit 41 determines whether or not an event is proposed, the meeting time, the user U who participates in the proposed event, and the non-participation after expressing participation in the proposed event. It may be configured to determine at least one of the users U who have expressed

FIG. 8 is a diagram showing an example of a group chat screen displayed on the display unit 11 of the terminal device 2 according to the embodiment. In the example shown in FIG. 8, the determination unit 41 determines whether or not there is an event proposal based on the group chat message. For example, when there is a message "Would you like to go somewhere next Sunday?", the determination unit 41 determines that the message suggests an event for the next Sunday.

Then, the determination unit 41 determines users U who will participate in the proposed event from the group chat messages. For example, if the message "Would you like to go somewhere next Sunday?" The user U who sent the message is determined as the user U participating in the proposed event.

[4.3.3. decision unit 42]
When the determination unit 41 determines that two or more users U plan to act together, the determination unit 42 shown in FIG. 4 determines candidates for the meeting place where the two or more users U meet. do.

For example, the determination unit 42 determines candidates for the meeting place of the two or more users U based on the bases of the two or more users U determined by the determination unit 41 to plan to act together. Hereinafter, a meeting place for two or more users U determined by the determination unit 41 to be together in action may be simply referred to as a meeting place.

The determining unit 42 acquires from the user information storage unit 30 the information of the bases of the two or more users U determined by the determination unit 41 as planning to act together, and stores the acquired information of the bases of the two or more users U. Based on this, candidates for the meeting place are determined. Hereinafter, the user U determined by the determining unit 41 as having a plan to act together may be referred to as a participating user UJ.

For example, the determination unit 42 determines candidates for the meeting place within the centroid area between the bases of two or more participating users UJ. The center-of-gravity area is, for example, a range set in advance from the center-of-gravity positions of the bases of two or more participating users UJ. The preset range is from D1/Db to 2×D1/Db [km] when the distance from the base of each participating user UJ to the center of gravity is D1 [km]. Db is, for example, 1/10 the distance of D1.

Here, participating users UJ are users U ₁ , U ₂ , and _Un , the position of user U ₁ is at latitude x1 and longitude y1, and the position of user _U2 is at latitude x2 and longitude y2. , and that the location of user U _n is at latitude x3 and longitude y3. In this case, the positions of the centers of gravity of the bases of users U ₁ , U ₂ , and U _n have a latitude of (x1+x2+x3)/3 and a longitude of (y1+y2+y3)/3.

In addition, the determination unit 42 determines the travel distance from the two or more participating users UJ's bases, the travel cost from the two or more participating users UJ's bases, and the state of the transportation network between the two or more participating users UJ's bases. Candidate meeting places can also be determined based on at least one of .

For example, the determining unit 42 can determine, as a meeting place candidate, a position within a range in which variations in travel distance from the base of each participating user UJ are set in advance. For example, the moving distance of each participating user UJ from the base is within a preset range (for example, the range of 0.8 to 1.2 times) with respect to the average value of the moving distance from the base of the participating user UJ position can be determined as a candidate for the meeting place.

Further, based on the movement history of the participating user UJ stored in the history information storage unit 33, the determining unit 42 selects a meeting place candidate for a position where the longer the traveling distance of the participating user UJ on weekdays or holidays is, the longer the traveling distance is. can be determined as

In addition, the determination unit 42 can determine candidates for the meeting place based on the average distance traveled by each participating user UJ to the meeting place in the past. For example, the determination unit 42 determines that the travel distance from the base of the participating user UJ who traveled a long distance to the meeting place in the past is longer than the travel distance from the base of the participating user UJ who traveled a short travel distance to the meeting place in the past. A location can be determined as a candidate for a rendezvous point.

It is also assumed that the combination of participating users UJ scheduled to participate in the event is the same as the combination of users U who participated in past events. In this case, the determination unit 42 determines that the travel distance from the base of the participating user UJ who traveled a long distance to the meeting place in the past is longer than the travel distance from the base of the participating user UJ who traveled a short travel distance to the meeting place in the past. Long or short locations can also be determined as candidate rendezvous points.

Further, the determining unit 42 can determine, as a meeting place candidate, a position where variation in travel costs from the base of each participating user UJ is within a preset range. For example, the moving cost of each participating user UJ from the base is within a preset range (for example, 0.8 times to 1.2 times the average value of the moving cost from the base of the participating user UJ) position can be determined as a candidate for the meeting place.

Further, based on the annual income of each participating user UJ, the determining unit 42 can determine, as a meeting place candidate, a position where at least one of the travel cost and the travel distance is higher for a participating user UJ with a higher annual income. Further, based on the interest of each participating user UJ, the determining unit 42 selects, as a meeting place candidate, a position where at least one of the movement cost and the movement distance is higher for the participating user UJ who is more interested in the scheduled event. can decide.

Further, the determination unit 42 can determine candidates for the meeting place based on the state of the transportation network between the bases of two or more participating users UJ. For example, the determining unit 42 selects a meeting place for a position where variation in travel time from each participating user UJ's base is within a preset range based on the state of the transportation network between the bases of two or more participating users UJ. can be determined as a candidate for For example, with respect to the average value of the travel time from the base of the participating user UJ, the travel time from the base of each participating user UJ is within a preset range (for example, the range of 0.8 to 1.2 times) position can be determined as a candidate for the meeting place.

The state of the transportation network includes, for example, at least one of the operation state of transportation facilities and the traffic congestion state of the road network. This state is predicted when moving to a place to meet up.

For example, when delays, suspensions, or accidents of transportation facilities occur or are predicted to occur due to accidents or weather, the determination unit 42 determines meeting place candidates when there are no delays, suspensions, or accidents of transportation facilities. Candidates for different meeting places can be determined. For example, the determination unit 42 determines the first station as a candidate for a meeting place when traveling on the first line if there is no suspension of the first line, but if there is a suspension of the first line , a second station different from the first station can be determined as a candidate for the meeting place when traveling on a second line different from the first line.

Further, the determination unit 42 selects a position where the values obtained by weighting at least two of the travel distance, travel cost, and travel time from the base of each participating user UJ fall within a preset range. can be determined as a candidate for

In addition, when the distance between the bases of two or more participating users UJ exceeds a preset distance, the determination unit 42 determines the area of the range set in advance from one of the bases of the two or more participating users UJ. Candidates for meeting places can also be determined within the system. In this case, if the distance between the bases of two or more participating users UJ does not exceed a preset distance, for example, the determining unit 42 may use the above-described various determination methods based on the bases of two or more participating users UJ. can be determined as a candidate for the meeting place.

In addition, the determining unit 42 can also determine candidates for meeting places based on the positions of two or more users U when the two or more users U send group chat messages to act together. The determination unit 42 determines the position of the user U based on user information included in the user information storage unit 30 .

For example, assume that the group chat message is "Would you like to have a drink in one hour?" In this case, the meeting date and time is one hour after the current time, and the time until the meeting is short. Therefore, the determination unit 42 determines candidates for the meeting place based on the position of each user U when a message expressing participation such as "Shall we go?" is sent as a group chat message, for example.

The determining unit 42 determines a candidate meeting place based on the location of each user U based on the position of each user U when the message expressing participation was sent instead of the location of each user U, and a method similar to the method of determining candidates for the meeting place based on the location of each user U. , a candidate for a meeting place can be determined. For example, the determination unit 42 can determine candidates for the meeting place within the centroid region of the position of each user U when the message expressing participation was transmitted. In addition, the determination unit 42 can determine candidates for the meeting place based on at least one of the travel distance, travel time, and travel cost from the position of each user U when the message expressing participation is transmitted. can.

Further, the determining unit 42 is closer to the location of the base of the participating user UJ who provided points for determining the meeting location than the location of the location of the base of the participating user UJ who did not provide points for determining the meeting location. A location can also be determined as a candidate for a meeting place. The points are points accepted by the accepting unit 43, and for example, points that can be used to purchase chat stamps. It may be a point used for

Each time a meeting place is determined, the determining unit 42 can determine a meeting place candidate such that a participating user UJ who has provided higher points is closer to the base. Note that the determination unit 42 can give the points provided by the participating users UJ to the participating users UJ who have not provided the points. Further, when points are provided from a plurality of participating users UJ, the determining unit 42 divides the total points provided by the plurality of participating users UJ by the total number of participating users UJ, It can also be given to UJ.

The determination unit 42 can preferentially determine a place suitable as a meeting place, for example, in front of a station, at the entrance of a park, or at the entrance of a commercial facility, as a candidate for the meeting place. For example, the information processing apparatus 1 can determine a place that is often used as a meeting place as a meeting place candidate.

The determination unit 42 can also determine candidates for the meeting place of two or more users U who are determined to be traveling together, based on past meeting place information of two or more participating users UJ. . In addition, based on the past meeting place information and base information of the two or more participating users UJ, the determination unit 42 determines the position in the intermediate region between the past meeting place of the two or more participating users UJ and the centroid region. can be determined as a candidate for the meeting place. Further, the determining unit 42 can, for example, prioritize the past meeting places of two or more participating users UJ as meeting place candidates in the centroid area based on the bases of the two or more participating users UJ.

Further, the determining part 42 updates the meeting place candidates when the determining part 41 determines that the combination of two or more users U participating in the event is changed after determining the meeting place candidates. The method of updating the meeting place candidates in this case is the same as the above-described method of determining the meeting place candidates by the determining unit 42 .

The determination unit 42 updates the candidates for the meeting place described above until it is predicted that two or more participating users UJ will arrive at the updated meeting place by the meeting time determined by the determination unit 41. be able to. For example, the decision unit 42 determines whether each participating user UJ has arrived at the meeting place based on the current position of each participating user UJ indicated by the user information stored in the user information storage unit 30 and information such as a transportation network. Calculate

The determining unit 42 determines whether the two or more participating users UJ who will participate in the event are expected to arrive at the updated meeting place by the meeting time determined by the determining unit 41. If the determination unit 41 determines that the combination of U has changed, the candidates for the meeting place can be updated. On the other hand, when it is predicted that two or more participating users UJ will not arrive at the meeting place by the meeting time decided by the deciding part 41, the decision part 42 does not update the meeting place candidates.

Further, the determining unit 42 keeps the meeting place of the participating users UJ until the estimated arrival time of the two or more participating users UJ at the updated meeting place by the meeting time determined by the determining unit 41 . Candidate meeting points can be updated if conditions change in the transit network used to travel to.

For example, when a delay, suspension, or accident of transportation occurs due to an accident or weather, the determination unit 42 determines whether two or more participating users UJ have arrived at the updated meeting place. Candidates for the meeting place can be updated until the expected meeting time.

For example, assume that an accident occurs on the first route after the determination unit 42 has determined the first station as a meeting place candidate for travel on the first route. In this case, the determination unit 42 determines that the arrival of the two or more participating users UJ at the meeting place after the update is predicted to be in time for the meeting time determined by the determination unit 41. can determine the first station as a candidate for the meeting place by traveling on a different second route.

Further, the determination unit 42 shifts the position of the determined meeting place candidate based on the group chat message by at least one of the two or more participating users UJ, and updates the meeting place candidate. can be done.

For example, after the information on the determined meeting place candidate is displayed on the display unit 11 of the terminal device 2, the determination unit 42 adds a character string requesting a change of the meeting place candidate to the message of the group chat by the participating user UJ. If it contains , update the meeting place candidates.

For example, it is assumed that a group chat message by participating user UJ includes a character string "It's a little far away." In this case, the determination unit 42 can shift the meeting place candidate to a position closer to the base of the participating user UJ who sent the message including the character string "It's a little far away."

It is also assumed that a group chat message by participating user UJ includes a character string such as "A place near Mr. XX is fine." In this case, the determining unit 42 can shift the meeting place candidate to a position closer to the base of the participating user UJ corresponding to “Mr.

Further, when the message of the group chat from the participating user UJ is positive for the meeting place candidate, the determination unit 42 can estimate that the meeting place has been determined.

FIG. 9 is a diagram showing still another example of the group chat screen displayed on the display unit 11 of the terminal device 2 according to the embodiment. In the example shown in FIG. 9, the information of the meeting place candidates determined by the determination unit 42 is displayed on the display unit 11 of the terminal device 2 as the message RC10 of the group chat. The group chat message RC10 is "Would you like to meet at place B?"

Then, in the example shown in FIG. 9, each participating user UJ responds to the candidates for the meeting place determined by the determination unit 42 by saying, "I am OK." A positive response message is sent as a group chat message. In this case, the determination unit 42 can presume that the place B has been determined as the meeting place.

[4.3.4. reception unit 43]
The accepting unit 43 shown in FIG. 4 accepts provision of points from at least one participating user UJ among two or more participating users UJ. The provision of such points is performed in order to bring the meeting place closer to the base of the participating user UJ. When the reception unit 43 receives the provision of points, the determination unit 42 determines a meeting place candidate at a position near the base of the participating user UJ who has provided the points, as described above.

[4.3.5. Estimation unit 44]
The estimation unit 44 shown in FIG. 4 estimates stores that two or more participating users UJ are likely to visit within the center of gravity area determined by the determination unit 41 . For example, the estimation unit 44 estimates shops that two or more participating users UJ are likely to visit based on the movement history of each participating user UJ in the center of gravity area.

For example, based on the movement history of each participating user UJ in the center-of-gravity region, the estimating unit 44 determines which of the two or more participating users UJ has been visited by at least one of the participating users UJ, or has been visited by a plurality of participating users UJ. Stores that have been visited are estimated as stores that two or more participating users UJ are likely to visit.

Based on the movement history of each participating user UJ in the centroid area, the estimating unit 44 selects a shop with a high word-of-mouth evaluation from two or more participating users UJ among the shops on the route where the participating user UJ is expected to move. It can also be estimated as a store that is likely to go to. Note that the acquisition unit 40 can acquire word-of-mouth information, which is information on word-of-mouth evaluation of a store, from a server device of a word-of-mouth site. A store with a high evaluation can be estimated as a store that two or more participating users UJ are likely to visit.

Note that the estimating unit 44 can also estimate shops that two or more participating users UJ are likely to visit after the determining unit 42 has determined the meeting place. In this case, the estimation unit 44 does not estimate the shops likely to be visited by two or more participating users UJ before the determination unit 42 estimates that the meeting place has been determined.

Further, when the determining unit 42 determines meeting place candidates in an area different from the center of gravity area, the estimating unit 44 selects shops that two or more participating users UJ are likely to visit within the area including the meeting place candidates. presume.

[4.3.6. Transmitter 45]
The transmitting unit 45 shown in FIG. 4 transmits the information of the meeting place candidates determined by the determining unit 42 as a group chat message. As a result, the information of the meeting place candidates is displayed on the terminal device 2 of the user U participating in the chat group.

FIG. 10 is a diagram showing still another example of the group chat screen displayed on the display unit 11 of the terminal device 2 according to the embodiment. A group chat message RC10 shown in FIG. 10 is a meeting place determined by the determination unit 42 after it is determined by the determination unit 42 that two or more users U are scheduled to act together from the group chat message shown in FIG. This is information on candidates for

In the example shown in FIG. 10, the information of the meeting place candidates determined by the determination unit 42 is displayed on the display unit 11 of the terminal device 2 as the message RC10 of the group chat. Such a message RC10 is "Would you like to meet at place B?"

Further, when the determining unit 42 updates the meeting place candidates, the transmitting unit 45 transmits information on the updated meeting place candidates as a group chat message. FIG. 11 is a diagram showing an example of updated meeting place candidates displayed on the group chat screen displayed on the display unit 11 of the terminal device 2 according to the embodiment.

In the example shown in FIG. 11, a group chat message CT16 indicating that one of the participating users UJ is unable to participate is transmitted from the terminal device 2 of one of the participating users UJ, and the message CT16 is displayed on the terminal device 2. It is shown in Part 11.

The message CT16 contains the character string "I'm sorry. I can't come this Sunday." Based on the character string included in the message CT16, the determining unit 42 determines that the user U of the terminal device 2 that transmitted the message CT16 cannot participate in the event. Then, the determination unit 42 updates the meeting place candidates based on the changed combination of participating users UJ. For example, if the participating users UJ before the change are users U ₁ , U ₂ , and _Un , and user _Un is unable to participate, candidates for the meeting place are determined based on the bases or positions of users U ₁ and U ₂ . Update.

On the group chat screen shown in FIG. 11, after the message CT16 is transmitted, the group chat message RC12 including information on the meeting place candidates updated by the determination unit 42 is displayed on the display unit 11 of the terminal device 2. . Specifically, message RC12 shown in FIG. changed to C. This allows the participating user UJ to grasp the updated meeting place candidates.

In addition, the transmission unit 45 transmits a message including a reservation button of a shop where two or more participating users UJ are likely to go to the terminal device 2 of the user U participating in the chat group as a group chat message by the estimation unit 44. .

FIG. 12 is a diagram showing an example in which a message including a reservation button is displayed on the group chat screen displayed on the display unit 11 of the terminal device 2 according to the embodiment. In the example shown in FIG. 12, a message including a reservation button BT11 of a store estimated by the estimation unit 44 that two or more participating users UJ are likely to visit is displayed on the display unit 11 of the terminal device 2 as a group chat message RC11. there is

Participating user UJ selects the reservation button BT11 included in the message RC11 by operating the operation unit 12 to display the reservation page of the store reservation site on the display unit 11 of the terminal device 2, or to display the reservation page of the store from the reservation page. You can make a reservation.
