Abstract

A method, system, and apparatus are provided for maintaining user privacy in a knowledge interchange (“KI”) system. A user may provide privacy preferences relating to their participation in the KI system. The user may identify specific keywords, noun phrases, and contacts that should not be transmitted to a server computer. The user may also specify whether each keyword, noun phrase, or contact should be public or private. If a public keyword is identified during a search query as being associated with the user, the user'"'"'s identity will be made available to a seeker If a private keyword is identified during a search query as being associated with the user, the user'"'"'s identity will not be made available and a brokered communication process between the seeker and the user will be performed.

assigning a respective weight to each of the individuals related to the at least one item of interest, the assigned weight being dependant on a respective relationship between each of the individuals and the at least one item of interest, wherein the respective relationship between each of the individuals and the at least one item of interest is determined by contacts listed a header field of at least one of the following;

the electronic mail message, the calendar meeting, and the instant message;

identifying keywords within the at least one item of interest;

allocating a respective weight to each keyword based on their location in the at least one item of interest and the frequency of the appearance of the keyword in the item of interest;

receiving knowledge interchange profiles from at least one user of the knowledge interchange system and storing the profiles in a profile database, wherein each knowledge interchange profile comprises at least one of the following;

a keyword, a noun phrase, and a contact;

receiving privacy preferences from each user of the knowledge interchange system, the privacy preferences specifying a type of data to be collected by the knowledge interchange system and how the data to be collected by the knowledge interchange system is to be utilized;

storing the privacy preferences;

receiving a request to query the profile database;

performing the received query over the profile database to identify search results;

determining whether the search results include a contact that was identified based upon private privacy preferences within the knowledge interchange profile of the contact;

in response to determining that the search results include the contact that was identified based upon private privacy preferences within the knowledge interchange profile on the contact, performing a brokered communication process between the user submitting the search query and the identified contact wherein prior to transmitting the request for assistance to the identified contact a determination is made based on privacy preferences for the identified contact whether the identified contact has been contacted for assistance more than a specified number of times within a predefined period of time and, if the identified contact has been contacted more than the specified number of times not transmitting the request for assistance;

determining whether the search results include a contact that was identified based public privacy preferences within the knowledge interchange profile of the contact; and

in response to determining that the search results include the contact that was identified based upon public privacy preferences within the knowledge interchange profile of the contact, transmitting the identity of the identified contact to the user submitting the search query with the search results.

9. The method of claim 8, wherein the brokered communication process comprises:

transmitting the query results to the user submitting the search query, the query results identifying the identified contact anonymously;

receiving a request from the user submitting the search query to contact the identified contact;

in response to receiving the request, transmitting a request for assistance to the identified contact on behalf of the user submitting the search query;
