Abstract

An event data processing apparatus calculates a meeting person number difference which is a difference in the number of meeting persons between a first number of meeting persons at a first time and a second number of meeting persons at a second time, determines that a continuous communication is conducted between the first time and the second time if the meeting person number difference is equal to or smaller than a meeting person number threshold value which is a predetermined threshold value, and records persons included in the first number of meeting persons and the second number of meeting persons, the first time, and the second time in association with event identifiers for identifying events in a recording module.

Claims

1. An event data processing apparatus, comprising:

a recording module that stores meeting information including a time, person information, and data indicating that the persons meet each other therein;

an input module that receives an input of the meeting information, and records the meeting information in the recording module;

a control module that calculates the number of meeting persons who meet each other according to the meeting information of the input received by the input module, calculates a meeting person number difference which is a difference in the number of meeting persons between a first number of meeting persons at a first time and a second number of meeting persons at a second time, determines that a continuous communication is conducted between the first time and the second time if the meeting person number difference is equal to or smaller than a meeting person number threshold value which is a predetermined threshold value, and records persons included in the first number of meeting persons and the second number of meeting persons, the first time, and the second time in association with event identifiers for identifying events; and

an output module that outputs the recorded event identifiers.

2. The event data processing apparatus according to claim 1,

wherein the control module calculates meeting member information which is information related to members of the meeting persons according to the meeting information of the input received by the input module, calculates a member match rate which is the degree of match between first meeting member information at the first time and second meeting member information at the second time, determines that a continuous communication is conducted between the first time and the second time if the member match rate is equal to or larger than a member match rate threshold value which is a predetermined threshold value, and records the persons included in the first number of meeting persons and the second number of meeting persons, the first time, and the second time in association with the event identifiers for identifying the events in the recording module.

5. The event data processing apparatus according to claim 1, further comprising a screen,

wherein the output module displays the event identifiers on the screen.

6. The event data processing apparatus according to claim 1, further comprising a screen,

wherein the input module receives an input of the meeting person number threshold value.

7. The event data processing apparatus according to claim 1,

wherein the input module receives an input of a time interval between the first time and the second time.

8. The event data processing apparatus according to claim 2,

wherein the input module receives an input of the member match rate threshold value.

9. The event data processing apparatus according to claim 1,

wherein the meeting information includes communication information of infrared rays.

10. The event data processing apparatus according to claim 1,

wherein the input module receives inputs of comments on the events identified by the event identifiers, and stores the comments in association with the event identifiers in the memory module.

11. The event data processing apparatus according to claim 1,

wherein the person information includes group information to which the persons belong.

12. The event data processing apparatus according to claim 11, further comprising a screen,

wherein the output module controls display of the event identifiers on the screen on the basis of whether the event is associated with the person belonging to the group identified by the group information, or not.

15. The event data processing apparatus according to claim 2,

wherein the control module determines whether a first event and a second event are associated together, or not, on the basis of a time overlap ratio of the first event and the second event, and a member overlap ratio of meeting member information of the first event and the second event, and if the first event and the second event are associated together, the control module records the first event and the second event newly as a third event in the recording module.

3. An event data processing apparatus, comprising:

a recording module that stores the meeting information including the time, the person information, and the data indicating that the persons meet each other therein, and motion information which is information related to the motions of bodies in association with each other;

an input module that receives inputs of the meeting information and the motion information, and records the meeting information and the motion information in the recording module;

a control module that calculates meeting time zones which are time zones during which the persons meet each other according to the meeting information of the input received by the input module, calculates motion values which are the degree of motion of the persons according to the motion information of the input received by the input module, calculates an evaluation index which is a value obtained by dividing a length of the time zone during which the motion value is equal to or larger than a first motion threshold value which is a predetermined threshold value among the meeting time zones by a length of the time zone in which a time zone during which a state where the motion value is equal to or smaller than a second motion threshold value which is a predetermined threshold value continues for a given time or longer is removed from the meeting time zone, and records the calculated evaluation index in association with the meeting information in the recording module; and

an output module that outputs the recorded evaluation index.

4. The event data processing apparatus according to claim 3,

wherein the motion information includes a frequency of acceleration or a zero cross value.

13. The event data processing apparatus according to claim 3,

wherein the control module calculates the evaluation indexes for a plurality of different meeting time zones, and calculates time rates of change of a plurality of the calculated evaluation indexes, and

wherein the output module outputs the time rates of change.

14. The event data processing apparatus according to claim 3,

wherein the meeting information is acquired by using an infrared communication and a location beacon.
