DETECTING ANOMALIES IN WORK PRACTICE DATA BY COMBINING MULTIPLE DOMAINS OF INFORMATION
First Claim
1. A computer-executable method for multi-domain clustering, comprising:
- collecting domain data for at least two domains associated with users, wherein a domain is a source of data describing observable activities of a user;
estimating a probability distribution for a domain associated with the user;
estimating a probability distribution for a second domain associated with the user; and
analyzing the domain data with a multi-domain probability model that includes variables for two or more domains to determine a probability distribution of each domain associated with the probability model and to assign users to clusters associated with user roles.

Abstract
One embodiment of the present invention provides a system for multi-domain clustering. During operation, the system collects domain data for at least two domains associated with users, wherein a domain is a source of data describing observable activities of a user. Next, the system estimates a probability distribution for a domain associated with the user. The system also estimates a probability distribution for a second domain associated with the user. Then, the system analyzes the domain data with a multi-domain probability model that includes variables for two or more domains to determine a probability distribution of each domain associated with the probability model and to assign users to clusters associated with user roles.
