Making Electronic Commerce Easier to Use with Novel User Interfaces

As discussed earlier, these scenarios are of two types: fixed form (manually developed) and parameter driven (expert system) For the fixed form scenarios, users need only select the scenario, and the transaction procedure is determined. For parameter driven scenarios, a user-dialog is needed to determine the situational characteristics. As with other aspects of contract negotiation, this will proceed from one party to another in an offer, counteroffer, acceptance sequence. Once this dialog is complete, the inference engine will assemble the trade scenario.
