Incorporating Extra-Linguistic Information into Reference Resolution in Collaborative Task Dialogue
Ryu Iida, Syumpei Kobayashi, Takenobu Tokunaga · 2010
This paper proposes an approach to ref-erence resolution in situated dialogues by exploiting extra-linguistic information. Recently, investigations of referential be-haviours involved in situations in the real world have received increasing attention by researchers (Di Eugenio et al., 2000; Byron, 2005; van Deemter, 2007; Spanger et al., 2009). In order to create an accurate reference resolution model, we need to handle extra-linguistic information as well as textual information examined by exist-ing approaches (Soon et al., 2001; Ng and Cardie, 2002, etc.). In this paper, we incor-porate extra-linguistic information into an existing corpus-based reference resolution model, and investigate its effects on refer-ence resolution problems within a corpus of Japanese dialogues. The results demon-strate that our proposed model achieves an accuracy of 79.0 % for this task. 1
