Abstract

An apparatus, system, and method are disclosed for generating hierarchical categories from collection of related terms. The collection of terms and their interrelationships is accumulated and stored in a database module together with a communication history. An input/output (I/O) module communicates the interrelationships to a plurality of users. The users select and possibly rank hierarchical (parent-child) interrelationships. The I/O module receives selected interrelationships from the users. An integration module creates weighted directed graphs of terms and selected interrelationships according to an integration policy. A cycle-breaking module breaks any cycles in the graphs. A selection module creates a hierarchical structure by selecting one primary parent node (parent category) for each node (term) in the graphs.

Claims

1. An apparatus for generating hierarchical categories from collection of related terms, the apparatus comprising:

a database module configured to store interrelationships between terms and communication history;

an input/output (I/O) module configured to communicate the interrelationships to a plurality of users and receives selected hierarchical interrelationships from the users;

an integration module configured to create weighted directed graphs of terms and selected interrelationships according to an integration policy;

a cycle-breaking module configured to break any cycles in the weighted directed graphs; and

a selection module configured to create a hierarchical structure from the graphs by selecting one primary parent node (parent category) for each node (term) in the graphs.

2. The apparatus of claim 1, wherein the integration policy comprises contribution shares of users, the integration module is further configured to calculate the weight of edge (interrelationship) as weighted sum of the contribution shares of users that select this interrelationship.

3. The apparatus of claim 1, wherein the selecting module is configured to select one primary parent node with maximum weight for each node in the graphs.

4. The apparatus of claim 1, wherein the I/O module is configured to receive only one selected parent-child interrelationship (parent category) for each term from each user.

5. The apparatus of claim 1, wherein the I/O module is configured to allow a user to select and rank hierarchical interrelationships, and the integration module is further configured to increase the weights of interrelationships with higher ranks in the graphs.

6. The apparatus of claim 1, wherein the input/output (I/O) module is configured to receive suggestions from the users about new terms and new hierarchical interrelationships and to update the database.

7. The apparatus of claim 1, wherein the term “

users”

means people, or organizations, or agents, or automatic programs.

8. The apparatus of claim 1, wherein the selection module is configured to build a Keywen structure that is a polyhierarchy which comprises one preferred tree that comprises all nodes of the polyhierarchy.

9. A computer program product comprising a computer useable medium having a computer readable program, wherein the computer readable program when executed on a computer causes the computer to:

accumulate and store interrelationships between terms and communication history;

communicate the interrelationships to a plurality of users that are selecting and possibly ranking hierarchical (parent-child) interrelationships;

receive selected interrelationships from the users;

create weighted directed graphs of terms and selected interrelationships according to an integration policy;

break any cycles in the weighted directed graphs; and

create a hierarchical structure from the graphs by selecting one primary parent node (parent category) for each node (term) in the graphs.

10. A system for generating hierarchical categories from collection of related terms, the system comprising:

a memory module configured to store software instructions and data;

a processor module configured to execute the software instructions and process the data and comprising;

a database module configured to store interrelationships between terms and communication history;

an input/output (I/O) module configured to communicate the interrelationships to a plurality of users and receives selected hierarchical interrelationships from the users;

an integration module configured to create weighted directed graphs of terms and selected interrelationships according to an integration policy;

a cycle-breaking module configured to break any cycles in the weighted directed graphs; and

a selection module configured to create a hierarchical structure from the graphs by selecting one primary parent node (parent category) for each node (term) in the graphs.

11. A method for deploying computer infrastructure, comprising integrating computer readable code into a computing system, wherein the code in combination with the computing system is capable of performing the following:

storing interrelationships between terms and communication history;

communicating the interrelationships to a plurality of users, receiving selected hierarchical interrelationships from the users;

creating weighted directed graphs of terms and selected interrelationships;

breaking any cycles in the weighted directed graphs; and

selecting one primary parent node (parent category) for each node (term) in the graphs.
