For the past dozen years, a team at RTI has developed behavioral software and applications that enable synthetic characters to act and behave realistically in controlled learning contexts, for interaction skills training and assessment. Applications include training civilian police officers in how to handle encounters with mentally disturbed individuals, assessing medical practitioners in history taking for both asthmatic and pediatric patients, monitoring the transmission and verification of Intelligence information, and training telephone and field interview staff in obtaining respondent participation. Much of the research has involved carefully-designed dialog models to enable natural flow and the eliciting or provision of necessary information between conversational partners. This presentation will address dialog design issues including coverage of content, consideration of social roles, biased reasoning, sensitive topics, and lexical and syntactic constraints.
