    <Paragraph position="0"> We present dialogue mallagement using two concel)t-level CMs in order to realize rolmst illteractioll. The content-word CM provides a criterion to decide whether an interpretation should be accel)ted, confirmed, or rejected. This strategy is realized by setting two thresholds that are optimized balancing false acceptance and false rejection. The interpretation error (FA+SErr) is reduced by 5.4% with no confirmation and by \] 1.5% with confirmations. Moreover, we &amp;',line CM on semantic attribut(~s, and propose a new met;hod to generate eilbx:tive guidances. The concept-t)ased (:onfidence measure realizes tlexible mixed-initiative dialogue in which the system can make effective contirmation and guidance by estimating user's intention. null</Paragraph>
