Abstract

A groupware computer system comprising a groupware server, a groupware client coupled to the server over a network, a contact information repository configured to store contact data of users in personal contact lists associated to individual users, a messaging system database configured to store statistical information about exchange of messages, a contact management module coupled to the contact information repository and configured to create, modify and retrieve contact data of users, a functional component for automatic determination of contact information (ADCI), and a groupware server computer, groupware client computer, a method, data processing program, computer program product, and computer data signal therefore.

Claims

1. A groupware computer system comprising:

a groupware server;

a groupware client coupled to the server over a network;

a contact information repository configured to store contact data of users in personal contact lists associated to individual users;

a messaging system database configured to store statistical information about exchange of messages;

a contact management module coupled to the contact information repository and configured to create, modify, and retrieve contact data of users; and

an automatic determination of contact information (ADCI) module being configured to;

retrieve contact data of a first user by;

querying the contact information repository for all personal contact lists that contain contact data of a first user to obtain a set of relevant contact lists;

determining an owner of each relevant contact list;

determining a contact frequency of the owner of each relevant contact list with the first user; and

determining an age of contact data comprised in each relevant contact list;

calculate a ranking score for each relevant contact list from the contact frequency of its owner and the age of contact data comprised therein; and

select a set of contact data for the first user from a predetermined amount of relevant contact lists in order of descending ranking score.

2. The system according to claim 1, wherein the ADCI module and the contact management module are comprised in the groupware server.

3. The system according to claim 1, wherein the ADCI module and the contact management module are comprised in the groupware client, and the contact information repository is coupled to the contact management module at the groupware client.

4. The system according to claim 3, further comprising a plurality of the groupware clients, wherein the personal contact lists are distributed over a number of contact information repositories coupled to the individual groupware clients, wherein the ADCI module is further configured to:

query the contact information repository for all contacts of the first user to obtain a set of relevant contacts;

determine the groupware clients of the relevant contacts;

send a request to the groupware clients of the relevant contacts to retrieve the contact data of the first user; and

aggregate retrieved contact data of the first user,

wherein the ADCI module is further configured to receive a request to retrieve the contact data of a first user and transmit the contact data accordingly.

5. The system according to claim 4, wherein the contact data comprise user categories and wherein the ADCI module is further configured to select additional contacts of the same user category as the first user when retrieving contact data, and is further configured to execute retrieving of contact data recursively at the groupware clients of the additional contacts until a specified depth of recursion is reached.

6. A method for contact data handling in a groupware computer system, comprising:

storing contact data of groupware system users in personal contact lists associated with individual groupware system users, the lists being stored in a contact information repository; and

retrieving contact data of a first user, wherein retrieving the contact data of a first user comprises;

querying the contact information repository for all personal contact lists that contain contact data of the first user to obtain a set of relevant contact lists;

determining an owner of each relevant contact list;

determining a contact frequency of the owner of each relevant contact list with the first user;

determining an age of contact data comprised in each relevant contact list;

calculating a ranking score for each relevant contact list from the contact frequency of its owner and the age of contact data comprised therein; and

selecting a set of contact data for the first user from a predetermined amount of relevant contact lists in the order of descending ranking score.

7. The method according to claim 6, wherein the personal contact lists are distributed over a number of contact information repositories coupled to individual groupware clients, and wherein the ADCI module of the groupware client of the first user is further configured to:

query the contact information repository for all contacts of the first user to obtain a set of relevant contacts;

determine the groupware clients of the relevant contacts;

send a request to the groupware clients of the relevant contacts to retrieve the contact data of the first user; and

aggregate retrieved contact data of the first user;

wherein the retrieving of contact data of the first user is performed on the respective groupware clients of the relevant contacts.

8. The method according to claim 7, wherein the contact data comprise user categories, the retrieving of contact data further comprising:

selecting additional contacts of the same user category as the first user, and wherein the retrieving of contact data is executed recursively by the groupware clients of the additional contacts until a specified depth of recursion is reached.

9. The method according to claim 7, wherein a groupware client discontinues processing upon determining that it is currently processing an identical request.

10. The method according to claim 7, further comprising:

querying a messaging system database for all contacts of the first user to add to the set of relevant contacts.

11. The method according to claim 6, wherein the contact data contain a visibility flag and a contact data element is processed only if the visibility flag is set to TRUE.

12. A program product stored on a computer readable medium, which when executed, handles contact data in a groupware computer system, the computer readable medium comprising program code for:

retrieving contact data of a first user by;

querying a contact information repository for all personal contact lists that contain contact data of a first user to obtain a set of relevant contact lists;

determine an owner of each relevant contact list;

determine a contact frequency of the owner of each relevant contact list with the first user; and

determine an age of contact data comprised in each relevant contact list;

calculate a ranking score for each relevant contact list from the contact frequency of its owner and the age of contact data comprised therein; and

select a set of contact data for the first user from a predetermined amount of relevant contact lists in order of descending ranking score.
