Verifying status of resources linked to communications and notifying interested parties of status changes

1. An information processing apparatus comprising a processor configured to:

obtain a chat message sent by a sender to a receiver and displayed in a user interface of a chat service;

extract resource information indicating a resource included in the content;

link the chat message, a notification destination, and the extracted resource information;

determine whether the resource information satisfies a predetermined condition comprising the resource information no longer being accessible,

determine whether the chat message corresponding to the resource information has been removed in response to the predetermined condition having been satisfied,

generate a notification as a return message corresponding to the notification destination to indicate that the resource information being not accessible in response to the predetermined condition having been satisfied and the chat message has not been removed, and

display the notification with the chat message in the user interface.

2. The information processing apparatus according to claim 1 , wherein in a case where the resource information included in the chat message is changed, the processor updates the resource information linked with the chat message to the changed resource information.

3. The information processing apparatus according to claim 2 , wherein in a case where the resource information included in the chat message is changed, the processor transmits the changed resource information to the notification destination.

4. The info illation processing apparatus according to claim 2 , wherein the processor transmits the notification to a notification destination designated from an outside the system as the notification destination linked with the resource information.

5. The information processing apparatus according to claim 1 , wherein the processor performs the linking as the chat message is obtained.

6. The information processing apparatus according to claim 5 , wherein the processor determines whether or not the resource is accessible according to the linking and in a case where the resource is not accessible, transmits the notification.

7. The information processing apparatus according to claim 1 , wherein the processor sets the notification destination as a notification destination determined according to a type of the chat message.

8. The information processing apparatus according to claim 7 , wherein in a case where the chat message is transmitted from a sender to a receiver, the processor sets the sender and the receiver as the notification destination.

9. The information processing apparatus according to claim 7 , wherein in a case where the chat message is accessed via a communication line, the processor sets an administrator of the chat message as the notification destination.

10. The information processing apparatus according to claim 1 , wherein the resource information is a uniform resource identifier or a uniform resource locator.

11. The information processing apparatus according to claim 1 , wherein the processor determines whether or not the resource is accessible at a predetermined timing regardless of whether or not the resource is accessed from the notification destination; and in a case where the resource is not accessible, the processor transmits the notification to the notification destination.

12. The information processing apparatus according to claim 1 , wherein the notification is displayed in a message form as a return message from the sender or the receiver to the content in the user interface.

13. A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:

obtaining a chat message sent by a sender to a receiver and displayed in a user interface of a chat service;

extracting resource information indicating a resource included in the content;

linking the chat message, a notification destination, and the extracted resource information;

determining whether the resource information satisfies a predetermined condition comprising the resource information no longer being accessible;

determining whether the chat message corresponding to the resource information has been removed in response to the predetermined condition having been satisfied;

generating a notification as a return message corresponding to the notification destination to indicate that the resource information being not accessible in response to the predetermined condition having been satisfied and the chat message has not been removed; and

displaying the notification with the chat message in the user interface.

14. An information processing method comprising:

obtaining a chat message sent by a sender to a receiver and displayed in a user interface of a chat service;

extracting resource information indicating a resource included in the content;

linking the chat message, a notification destination, and the extracted resource information;

determining whether the resource information satisfies a predetermined condition comprising the resource information no longer being accessible;

determining whether the chat message corresponding to the resource information has been removed in response to the predetermined condition having been satisfied;

generating a notification as a return message corresponding to the notification destination to indicate that the resource information being not accessible in response to the predetermined condition having been satisfied and the chat message has not been removed; and

displaying the notification with the chat message in the user interface.
