    <Paragraph position="0"> The MATE 'meta-scheme' for anaphora annotation (Poesio et al., 1999) is one of the annotation schemes developed as part of the MATE project (McKelvie et al., 2001), whose goal was to develop annotation tools suitable for different types of dialogue annotation. The scheme has served as the basis for a number of annotation projects, such as the development of the GNOME corpus (Poesio, 2000a) and, more recently, of the VENEX corpus of anaphora in Italian spoken dialogue and text (Poesio et al., 2004a). The GNOME corpus has been used to study salience, particularly as formalized in Centering theory (Poesio et al., 2004c), to develop statistical models of natural language generation (e.g., (Poesio, 2000a; Henschel et al., 2000; Cheng et al., 2001; Cheng, 2001; Karamanis, 2003)) and to evaluate anaphora resolution systems, with a special focus on the resolution of bridging references (Poesio, 2003; Poesio and Alexandrov-Kabadjov, 2004; Poesio et al., 2004b). Aspects of the scheme have been implemented in annotation tools including MMAX (M&amp;quot;uller and Strube, 2003) and the Annotator tool developed by ILSP. As a result of this work, many aspects of the proposals concerning anaphoric annotation made in MATE and GNOME have been subjected to a thorough test. In this paper we discuss some of the lessons learned through this work, some issues that have been raised, and how they have been or could be addressed.</Paragraph>
