Delivery Environment Instant Tea's delivery environment provides agents that guide users through question and answer sessions resulting in complete solutions. Users select from a menu of knowledge bases. The agent's retrieves the selected knowledge bases and its inference engine pursues the knowledge base's goals by querying the user and inferring solutions. When a users requests an explanation, an agent automatically retrieves remote HTML documents to help the user.
Users respond to agent questions by pointing and clicking on possible answers.
At anytime during a consultation users may reset the current knowledge base or select another knowledge base. Upon arriving at a conclusion, the agent may retrieve additional Web resources to clarify results. The user may then trace the inference chains that resulted in the agent's conclusion. Figure 3 shows the services provided by Instant Tea's Java agent. The agent takes advantage of browsers that support frames to offer a way to customize consultations at web sites.
