This paper addresses the representation of ellipsis in dependency syntax, proposing both a theoretical and a practical workflow for its analysis and annotation in treebanks, following the state-of-the-art Universal Dependencies framework. We discuss the challenges of annotating ellipsis, with a focus on predicate ellipsis and its representation in dependency treebanks, and emphasize the importance of accounting for such phenomena for syntactic analysis and machine learning applications. We present a case study based on the Italian-Old treebank, demonstrating the applicability of the proposed workflows and invite the community to participate in this initiative with their own languages.

This paper presents preliminary results of the development of the Egyptian-UJaen treebank, the first dependency treebank created for pre-Coptic Egyptian in Universal Dependencies. It describes the current state of the treebank, explains the approach adopted for the morphosyntactic annotation and discusses some issues concerning the adoption of the CoNLL-U format for the annotation of Egyptian texts. This treebank will surely become a useful linguistic tool for understanding the synchronic and dia- chronic use of pre-Coptic Egyptian.
