Abstract

A method for providing information to an instant messaging (IM) user includes sending information to the user via an instant message based on interest information provided by the user. The interest information may not be restricted to a predetermined set of interest information.

Claims

1. A method for providing information to an instant messaging (IM) user, the method comprising:

sending information to the user via an instant message based on interest information provided by the user, the interest information not being restricted to a predetermined set of interest information offered by an information provider.

2. The method of claim 1, further comprising:

receiving a text string, defining at least a portion of the interest information, from the user via the instant message and

using at least a portion of the text string as an interest item; and

wherein

the sending step sends the information to the user based on the interest item.

3. The method of claim 1, further comprising:

receiving priority information for one or more interest items; and

wherein

the sending step sends the information to the user based on the interest items and the priority information.

4. The method of claim 3, wherein the priority information is user defined priority information.

5. The method of claim 3, further comprising:

determining the relevance of an information item to a user based on the interest items and the priority information; and

wherein

the sending step sends the information item to the user based on the determined relevance.

6. The method of claim 5, wherein each interest item includes at least one keyword representing the interest item, and the determining step further comprises:

determining a frequency of each keyword in at least one information item; and

determining the relevance based on the determined frequencies of the interest items and the priority information.

7. The method of claim 6, wherein the priority information associated with an interest item includes a priority value associated with the keyword included in the interest item, and the determining of the relevance further comprises:

forming a user vector where each position in the vector is associated with a keyword and includes a priority value associated with the keyword; and

forming a source vector for an information item where each position within the source vector is associated with a keyword in the user vector and includes a value equal to the determined frequency of the keyword in the information item; and

determining the relevance as a dot product of the user and source vectors.

8. The method of claim 7, wherein the sending step further comprises:

sending the information items to the user in order of relevance.

9. The method of claim 7, wherein the sending step sends the information item based on a comparison of the determined relevance and a relevance threshold.

10. The method of claim 5, wherein the sending step further comprises:

sending the information item to the user in order of relevance.

11. The method of claim 1, further comprising:

determining the relevance of an information item to a user based on the interest information; and

sending the information item to the user based on the determined relevance.

12. The method of claim 11, further comprising:

receiving priority information for the interest information from the user; and

wherein

the determining step determines the relevance of the information item based on the interest information and the priority information.

13. The method of claims 11, wherein the sending step sends the information item based on a comparison of the determined relevance and a relevance threshold.

14. The method of claim 11, further comprising:

filtering the information item based on the determined relevance; and

wherein

the sending step sends the information item to the user if the information item passes the filtering step.

15. The method of claim 1, further comprising:

receiving priority information for the interest information from the user; and

wherein

the sending step sends the information to the user based on the interest information and the priority information.

16. The method of claim 1, wherein the interest information is not from a predetermined set of interest information offered by an information provider.

17. The method of claim 1, wherein at least a portion of the interest information is a text-string.

18. The method of claim 1, wherein at least a portion of the interest information is at least one word.

19. The method of claim 1, wherein at least a portion of the interest information is in a format.

20. A method for obtaining information via instant messaging (IM) services, the method comprising:

sending interest information, which is not restricted to a predetermined set of interest information, via a first instant message; and

receiving information, via a second instant message, based on the interest information provided via the first instant message.
