ASK systems are a form of hypermedia based on the metaphor of having a conversation with an expert (or a group of experts). In this conversation, the user provides questions and the ASK system provides the answers. In a real conversation, both participants influence the flow of discussion. In an ASK system, the same holds true. The user influences the flow by selecting which questions to pursue and the ASK system influences the flow through the answers it provides.
