Conversational Intelligent Tutoring Systems (ITSs) are expensive to develop. While simple online courseware could be easily authored by teachers, the authoring of conversational ITSs usually involves a team of experts with different expertise, including domain experts, linguists, instruction designers, programmers, artists, computer scientists, etc. Reducing the authoring cost has long been a problem in the use of ITSs. Using AutoTutor as example, this paper discusses the authoring process and possible solutions by automatizing some authoring processes in authoring conversational ITSs.
