TY - CONF A1 - Pfleger, Norbert A1 - Alexandersson, Jan T1 - Towards resolving referring expressions by implicitly activated referents in practical dialogue systems N2 - We present an extension to a comprehensive context model that has been successfully employed in a number of practical conversational dialogue systems. The model supports the task of multimodal fusion as well as that of reference resolution in a uniform manner. Our extension consists of integrating implicitly mentioned concepts into the context model and we show how they serve as candidates for reference resolution.
