2000 6 5 6 :, Supporting Conference Program Production Using Natural Language Processing Technologies Hiromi itoh Ozaku Masao Utiyama Masaki Murata Kiyotaka Uchimoto and Hitoshi Isahara We applied natural language processing technologies to automatically produce a program for the sixth annual meeting of the Association for Natural Language Processing. In this paper, we describe experiments used to automatically generate the program using the fifth annual meeting data. We produce the sixth annual meeting program on the basis of the experiments. We report the process of making the sixth annual meeting program in practice and show to what extent the natural language processing technologies are efficient for this task. Furthermore, we show the results of a questionnaire targeting the participants of the sixth annual meeting.
