WebTalk is an intelligent agent that automatically mines company websites to create interactive spoken and chat-based dialog systems.

We elaborate on an evaluation of the question answering component of WebTalk. In particular, we compare this component with a deployed hand-crafted question answering agent. A detailed evaluation analysis is presented.
