Abstract

A system and method of collecting information and associated context are provided. Information is retrieved using context information by receiving a search request to identify an information item, the search request including a context comprising circumstantial information related to a previous experience with the information item, and searching at least one data store using the context item, so as to identify the information item associated with the context.

Claims

1. A method executable by at least one computing system of retrieving information using context information comprising:

storing, by at least one processor in at least one data store, context identified from a previous experience with an information item, the stored context comprising information and events associated with the information item, event relationships among the events and an event type of each event, the stored context relates the information item and at least one of the events that occurred during the previous experience with the information item;

receiving, by the at least one processor, a request to search the stored context to identify the information item, the request comprising at least a portion of the stored context including the at least one event that occurred during the previous experience with the information item, the event type of the at least one event, and at least one of the event relationships;

searching, by at least one processor, the stored context using the at least a portion of the stored context included in the search request to identify the information item.

2. The method of claim 1, wherein the search request is received from an application program.

3. The method of claim 1, wherein the search request is received from a user.

4. The method of claim 1, wherein the information item is a document, and at least a portion of the context is stored as metadata associated with the document.

5. The method of claim 4, wherein the document is saved as a file and the context is stored as part of a file.

6. The method of claim 4, wherein the context is other than file system information associated with the file.

7. The method of claim 1, wherein the information item is an electronic mail message.

8. The method of claim 1, wherein the information item is an instant message.

9. The method of claim 1, wherein the information item is contact information.

10. A method comprising:

collecting, by at least one computing system, context for an information item, said step of collecting comprises;

identifying the context corresponding to the information item from a previous experience with the information item, the context comprising information and events, event relationships among the events identified from the previous experience with the information item, and an event type of each event, the stored context relates the information item and at least one of the events that occurred during the previous experience with the information item; and

storing the context in a data store; and

retrieving the information item, said step of retrieving comprising;

receiving a request to search the stored context to identify the information item, the request comprising search criteria comprising at least one item of the stored context, the search criteria including the at least one event that occurred during the previous experience with the information item, the event type of the at least one event, and at least one of the event relationships;

searching the stored context using the search criteria to identify the information item.

11. A computer-readable medium tangibly embodying a computer program, the computer program comprising:

storing, in at least one data store, context identified from a previous experience with an information item, the stored context comprising information and events associated with the information item, event relationships among the events and an event type of each event, the stored context relates the information item and at least one of the events that occurred during the previous experience with the information item;

receiving a request to search the stored context to identify the information item, the request comprising at least a portion of the stored context including the at least one event that occurred during the previous experience with the information item, the event type of the at least one event, and at least one of the event relationships;

searching the stored context using the at least a portion of the stored context included in the search request to identify the information item.

12. The computer-readable medium of claim 11, wherein the search request is received from an application program.

13. The computer-readable medium of claim 11, wherein the search request is received from a user.

14. The computer-readable medium of claim 11, wherein the information item is a document, and at least a portion of the context is stored as metadata associated with the document.

15. The computer-readable medium of claim 14, wherein the document is saved as a file and the context is stored as part of a file.

16. The computer-readable medium of claim 14, wherein the context is other than file system information associated with the file.

17. The computer-readable medium of claim 11, wherein the information item is an electronic mail message.

18. The computer-readable medium of claim 11, wherein the information item is an instant message.

19. The computer-readable medium of claim 11, wherein the information item is contact information.

20. A computer-readable medium tangibly embodying a computer program, the computer program comprising:

collecting context for an information item, said step of collecting comprises;

identifying the context corresponding to the information item from a previous experience with the information item, the context comprising information and events, event relationships among the events from the previous experience with the information item and an event type of each event, the stored context relates the information item and at least one of the events that occurred during the previous experience with the information item; and

storing the context in a data store; and

retrieving the information item, said step of retrieving comprising;

receiving a request to search the stored context to identify the information item, the request comprising search criteria comprising at least one item of the stored context, the search criteria including the at least one event that occurred during the previous experience with the information item, the event type of the at least one event, and at least one of the event relationships;

searching the stored context using the search criteria to identify the information item.
