The system of the present invention, discloses means for implementing the method.

Claims

1. A method for knowledge management, comprising:

generating a client computer profile from a set of data items on a client computer;

generating a set of message response profiles from a corresponding set of message responses;

generating a set of new message profiles from a corresponding set of new messages;

storing the profiles on the client computer; and

scoring a new message with respect to the client and message response profiles wherein each of the generating elements includes;

generating expertise vectors from data items in the client computer and the messages.

2. A method for knowledge management comprising:

generating a client computer profile from a set of data items on a client computer;

generating a set of message response profiles from a corresponding set of message responses which includes generating a set of generated message response profiles from a corresponding set of generated message responses;

generating a set of new message profiles from a corresponding set of new messages;

storing the profiles on the client computer; and

scoring a new message with respect to the client and message response profiles.

3. The method of claim 2, wherein the scoring element includes:

determining how related the new message profile is to the set of generated message response profiles.

4. The method of claim 3, wherein the determining element includes:

determining that messages are related if a distance between the messages'"'"' expertise vectors is less than or equal to a predetermined distance.

5. The method of claim 2, wherein:

the generating a set of generated message response profiles element includes, adding a message answered attribute to a generated message response profile, if a corresponding new message has been answered; and

the scoring element includes, increasing a new message'"'"'s score if the new message is related to a predetermined number of generated message responses having the message answered attribute.

6. The method of claim 2, wherein:

the generating a set of generated message response profiles element includes, adding a message deleted without response attribute to a generated message response profile, if a corresponding new message has been deleted; and

the scoring element includes, decreasing a new message'"'"'s score, if the new message is related to a predetermined number of generated message responses having the message deleted without response attribute.

7. The method of claim 2, wherein:

the generating a set of generated message response profiles element includes, adding a client user interested attribute to a generated message response profile, if a corresponding new message has been opened; and

the scoring element includes, increasing a new message'"'"'s score if the new message is related to a predetermined number of generated message responses having the user interested attribute.

8. The method of claim 2, wherein:

the generating a set of generated message response profiles element includes, adding a client user ignored attribute to a generated message response profile, if a corresponding new message has not been opened; and

the scoring element includes, decreasing a new message'"'"'s score if the new message is related to a predetermined number of generated message responses having the user ignored attribute.

9. The method of claim 2, wherein the generating a set of generated message response profiles element includes, adding a message answered attribute to a generated message response profile, if a corresponding new message has been answered;

and adding a message deleted without response attribute to a generated message response profile, if a corresponding new message has been deleted; and

the scoring element includes, determining that a new message and a generated response message having the message answered attribute are related if a distance between the messages'"'"' expertise vectors is less than or equal to a first predetermined distance; and

determining that a new message and a generated response message having the message deleted without response attribute are related if a distance between the message'"'"' expertise vectors is less than or equal to a second predetermined distance.

10. A method for knowledge management, comprising:

generating a client computer profile from a set of data items on a client computer;

generating a set of message response profiles from a corresponding set of message responses;

generating a set of new message profiles from a corresponding set of new messages;

storing the profiles on the client computer;

scoring a new message with respect to the client and message response profiles;

identifying a set of received message responses corresponding to a new message, from within the message responses;

adding a response count attribute to a new message profile corresponding to the new message; and

incrementing the response count attribute by one for each received message response in the set of received message responses.

11. The method of claim 10, wherein the scoring element includes:

calculating an elapsed time since a new message is first received by tile client computer;

retrieving the new message'"'"'s response-count from the client profile; and

periodically increasing the new messages score by a predetermined amount, if the new message'"'"'s response-count during the elapsed time is less than a predetermined minimum count.

12. The method of claim 10, wherein the scoring element includes:

calculating an elapsed time since a new message is first received by the client computer, retrieving the new message'"'"'s response-count from the client profile; and

periodically decreasing the new message'"'"'s score by a predetermined amount if the new message'"'"'s response-count during the elapsed time is greater than a predetermined maximum count.

13. The method of claim 10, wherein the identifying element includes:

identifying a message response ID within a received message response which corresponds with a new message ID within the new message.

14. A method for knowledge management, comprising:

generating a client computer profile from a set of data items on a client computer;

generating a set of message response profiles from a corresponding set of message responses;

generating a set of new message profiles from a corresponding set of new messages;

storing the profiles on the client computer;

scoring a new message with respect to the client and message response profiles; and

defining new messages as any message received by the client computer, having a message ID not previously observed.

15. A method for knowledge management, comprising:

generating a client computer profile from a set of data items on a client computer;

generating a set of message response profiles from a corresponding set of message responses;

generating a set of new message profiles from a corresponding set of new messages;

storing the profiles on the client computer;

scoring a new message with respect to the client and message response profiles; and

defining message responses as any messages received or generated by the client computer, which correspond to a previously received new message.

16. A system for knowledge management, comprising:

means for generating a client computer profile from a set of data items on a client computer;

means for generating a set of message response profiles from a corresponding set of message responses;
