Routing and filtering are terms used to describe the process of comparing 
text streams (such as newswire feeds) to the appropriate users. Although 
similar to the task of information retrieval, there are significant 
differences that impact on text representation, the retrieval model, and 
representing information needs as profiles.  In this talk, I will present 
a model of routing that uses Bayesian networks and a system implementation 
based on this model.  I will also compare approaches to learning profiles 
from examples of relevant and non-relevant texts.  Examples from 
applications and the government-sponsored TREC evaluations will be used 
to describe problems and solutions.
