23. A system for editing and displaying a structured argument, having a plurality of associated parameters, the system comprising: a processor, operative to execute computer executable instructions; and a computer readable medium that stores the computer executable instructions, the computer executable instructions comprising: a user interface that graphically displays the plurality of parameters, comprising a plurality of influence parameters representing the degree of logical relatedness between respective associated first and second hypotheses, at a user accessible display and receives input from a user defining the value of a selected parameter, wherein the influence parameters are displayed as connectors between respective first nodes, representing the associated first hypotheses, and respective second nodes, representing the associated second hypotheses, and the magnitude of a given influence parameter is represented by at least one spatial dimension of the associated connector of the influence parameter, wherein the plurality or parameters comprises respective confidence values for a plurality of hypotheses; and a computational engine that alters the selected parameter to the defined value, updates the plurality of parameters according to the defined value of the selected parameter, and provides the altered parameters to the user interface, such that the display is updated in real time to reflect the user input.
24. The system of claim 23 , at least one confidence value being displayed to a user via a first, qualitative indicator and a second, quantitative indicator.
