An attempt has been made to use an Augmented Transition Network IO as a 'procedural dialog model'. The development of such a model appears to be important in several respects: as a device to represent and to use different dialog schemata proposed in empirical conversation analysis; as a device to represent and to use models of verbal interaction; as a device combining knowledge about dialog sch...

Island parsing is a powerful technique for parsing with Augmented ~ansition Networks (ATNs) which was developed and successfully applied in the HWIM speech understanding project. The HWIM application grammar did not, however, exploit Woods' original full ATN specification. This paper describes an island parsing interpreter based on HWIM, but containing substantial and important extensions to en...
