Abstract

An information sharing system includes a computer network formed of terminals and a server and allows information about a posted message to be shared among users. The system or a terminal acquires a question message input via the terminal together with positional information associated with the question message and causes the acquired question message to be accessible to the users. The system or terminal acquires an answer message input by a respondent via the terminal as an answer to the question message and causes the acquired answer message to be accessible to the users. The system or terminal acquires positional information of the respondent and restricts the respondent accessing the question message on the basis of question positional information that is the positional information associated with the question message and respondent positional information that is the acquired positional information of the respondent.

Claims

1. An information sharing system in which, on a computer network formed of terminals of users and a server, information about a posted message posted by a user is shared among the users, the information sharing system comprising:

an electronic control unit including a processor programmed to;

acquire a question message input via a terminal together with positional information associated with the question message;

cause the acquired question message to be accessible to the users on the computer network;

acquire an answer message input via a sending terminal as an answer to the question message;

cause the acquired answer message to be accessible to the users on the computer network;

acquire positional information of a respondent that is one of the users that inputs the answer message;

restrict a questioner that is another one of the users that posted the question message from accessing the answer message based on question positional information that is the positional information associated with the question message and respondent positional information that is the acquired positional information of the respondent;

determine whether the question message is a question that requires an answer in real-time based on contents of the question message;

determine a type of an object that is a target for the question of the question message;

in response to determining that the question message requires the answer in real-time, set an access restriction condition based on the type of the object and the question positional information and restrict access to the answer message responsive to the respondent positional information satisfying the access restriction condition; and

in response to determining that the question message does not require the answer in real-time, allow the answer message to be accessed by the questioner and do not set the access restriction on the answer message.

2. The information sharing system according to claim 1, wherein the processor of the electronic control unit is programmed to:

acquire correspondence relationship information that associates whether the question requires an answer in real time with each of multiple-type fixed messages; and

determine whether the question message requires the answer in real time on the basis of the correspondence relationship information when the question message corresponds to any one of the multiple-type fixed messages.

3. The information sharing system according to claim 1, wherein the processor of the electronic control unit is programmed to determine whether the question message requires an answer in real time by performing a syntactic analysis on the question message.

4. The information sharing system according to claim 1, wherein the processor of the electronic control unit is programmed to set a range of the respondent who posts the answer message, to which restriction on access is applied, on the basis of a relationship between the question positional information and the respondent positional information.

5. The information sharing system according to claim 4, wherein the processor of the electronic control unit is programmed to apply the restriction on access to the answer message that is posted from the respondent who is located a predetermined distance or longer apart from a location that is identified by the question positional information.

6. The information sharing system according to claim 4, wherein the processor of the electronic control unit is programmed to apply the restriction on access to the answer message that is posted from the respondent who is not located at a location that is identified by the question positional information within a last predetermined period of time.

7. The information sharing system according to claim 4, wherein the processor of the electronic control unit is programmed to set the range of the respondent who posts the answer message, to which restriction on access is applied, on the basis of the relationship between the question positional information and the respondent positional information that indicates a location of the respondent at the time point at which the question message was posted or the time point at which the answer message to the question message is posted.

8. The information sharing system according to claim 1, wherein the processor of the electronic control unit is programmed to:

accept transmission the acquired answer message from the sending terminal to the server;

store the transmitted answer message in the server;

distribute the stored answer message from the server to an access terminal that intends to access the answer message for output on the access terminal; and

restrict the questioner from accessing the answer message by restricting the transmission of the answer message from the sending terminal to the server.

9. The information sharing system according to claim 1, wherein the processor of the electronic control unit is programmed to acquire information that identifies a location on a map, specified by the questioner, as the question positional information.

10. The information sharing system according to claim 1, wherein the processor of the electronic control unit is programmed to:

display a map image on the access terminal;

display a selection target at the location that is identified by the question positional information, associated with the acquired question message, on the map image displayed on an access terminal; and

when the selection target has been selected by a user, output the acquired question message from the sending terminal.

11. The information sharing system according to claim 10, wherein the processor of the electronic control unit is programmed to output the answer message together with the question message when the selection target displayed at the location that is identified by the question positional information, associated with the question message to which the answer message is made, has been selected by the user.

12. An information sharing method in which, on a computer network formed of terminals of users and a server, information about a posted message posted by a user is shared among the users, the method comprising:

question message information acquisition step of acquiring a question message input via the terminal together with positional information associated with the question message;

question message accessing step of causing the question message acquired in the question message information acquisition step to be accessible to the users on the computer network;

answer message information acquisition step of acquiring an answer message input via the terminal as an answer to the question message;

answer message accessing step of causing the answer message acquired in the answer message information acquisition step to be accessible to the users on the computer network;

respondent positional information acquisition step of acquiring positional information of a respondent that is one of the users that inputs the answer message;

access restriction step of restricting a questioner that is the user who posted the question message from accessing the answer message on the basis of question positional information that is the positional information associated with the question message and respondent positional information that is the positional information of the respondent, acquired in the respondent positional information acquisition step;

a first determining step of determining whether the question message is a question that requires an answer in real-time based on contents of the question message;

a second determining step of determining a type of an object that is a target for the question of the question message;

in response to determining that the question message requires the answer in real-time, an access restriction condition setting step of setting an access restriction condition based on the type of the object and the question positional information and restricting access to the answer message responsive to the respondent positional information satisfying the access restriction condition; and

in response to determining that the question message does not require the answer in real-time, an access allowing step of allowing the answer message to be accessed by the questioner and do not set the access restriction on the answer message.

13. A non-transitory computer-readable storage medium storing a computer-executable program for sharing information about a posted message posted by a user among a plurality of users, the program comprising:
