10. The method of claim 1 , wherein the information source comprises user preferences and user-specific data that is specific to the user.

11. The method of claim 1 , wherein the information source is a knowledge graph.

12. The method of claim 1 , wherein:

the action to be taken is presentation of a reminder at the user device; and

causing the action to occur comprises sending data to the user device that causes the user device to present the reminder.

13. The method of claim 1 , wherein:

the action to be taken is an action that is performed independent of the user device.

14. The method of claim 1 , wherein:

the action to be taken is presentation of a confirmation to take a second action;

causing the action to occur comprises sending data to the user device that causes the user device to present the confirmation; and

further comprising performing, by the action processing system, the second action in response to receiving from the user device data indication acceptance of the confirmation.

15. The method of claim 1 , wherein the first event is an event associated with the user.

16. The method of claim 1 , wherein the first event is an event independent of the user.

17. The method of claim 1 , wherein associating, by the action processing system, the action and the first event with instructions for determining if the first event has occurred comprises:

testing the first event for a valid condition; and

only associating the action and the first event with instructions for determining if the first event has occurred when the testing of the first even for an valid condition indicates the first event can occur.

18. The method of claim 1 , further comprising: wherein the at least one activity condition is at least one of a time period condition, a location area condition, and a person proximity condition.

19. An action processing system, comprising:

a processor; and

a computer-readable medium coupled to the processor and having instructions stored thereon, which, when executed by the processor, cause the processor to perform operations comprising:

receiving, from a user device, identification of an action to be taken, the action being one of a plurality of action types;
