  • System and method for converting graphical call flows into finite state machines
    Patent number: 8381200
    Abstract: A method, system and module for automatically converting a call flow into a state-based representation are disclosed. The method comprises walking a call flow and converting each page of the call flow into a rule of a higher level representation of the call flow, augmenting the higher level representation with terminal symbols representing state variable assignments and comparisons associated with decision and computation shapes in the call flow and converting the higher level representation into a state-based representation.
    Type: Grant
    Filed: May 3, 2011
    Date of Patent: February 19, 2013
    Assignee: AT&T Intellectual Property II, L.P.
    Inventors: Cecilia M. Castillo, Theodore J. Roycraft, James M. Wilson

  • Method for automatic graphical profiling of a system
    Patent number: 7881440
    Abstract: A method and apparatus for processing unique dialogs from a dialog system to identify paths through the dialog system, each unique dialog having a corresponding identified path and generating a visual call flow representation as a function of the identified paths of the dialog system, the call flow representation including nodes and edges connected to correspond to the identified paths.
