This paper describes novel results on the characteristics of three-party dialogues by quantitatively comparing them with those of two-party. In previous dialogue research, two-party dialogues are mainly focussed because data collection of multi-party dialogues is difficult and there are very few theories handling them, although research on multi-party dialogues is expected to be of much use in building computer supported collaborative work environments and computer assisted instruction systems. In this paper, firstly we describe our data collection method of multi-party dialogues using a meeting scheduling task, which enables us to compare three-party dialogues with those of two party | Exploring the Characteristics of Multi-Party Dialogues Masato Ishizaki Japan Advanced Institute of Science and Technology Tatsunokuchi Noumi Ishikawa 923-1292 Japan masato@ Tsuneaki Kato NTT Communication Science Labs. 2-4 Hikaridai Seika Souraku Kyoto 619-0237 Japan kato@cslab. keel. ntt. co. j p Abstract This paper describes novel results on the characteristics of three-party dialogues by quantitatively comparing them with those of two-party. In previous dialogue research two-party dialogues are mainly focussed because data collection of multi-party dialogues is difficult and there are very few theories handling them although research on multi-party dialogues is expected to be of much use in building computer supported collaborative work environments and computer assisted instruction systems. In this paper firstly we describe our data collection method of multi-party dialogues using a meeting scheduling task which enables US to compare three-party dialogues with those of two party. Then we quantitively compare these two kinds of dialogues such as the number of characters and turns and patterns of information exchanges. Lastly we show that patterns of information exchanges in speaker alternation and initiative-taking can be used to characterise three-party dialogues. 1 Introduction Previous research on dialogue has been mostly focussing on two-party human-human dialogue for developing practical human-computer dialogue systems. However our everyday communicative activities involves not only two-party communicative situations but also those of more than two-party we call this multi-party . For example it is not unusual for US to chitchat with more than one friend or business meetings are usually held among more than two participants. Recently advances of computer and networking technologies enable US to examine the possibility of using computers to assist effective communication in business meetings. As well as this line of computer assisted communication
