| Title: | On auxiliary verb in Universal Dependencies: untangling the issue and proposing a systematized annotation strategy |
| Authors: | Magali Duran Amanda Pontes Rassi Adriana Silvina Pagano Thiago Alexandre Salgueiro Pardo |
| Abstract: | Auxiliary verbs are universally recognized as components of verbal constructions. While there is no shortage of scholarship on these verbs in various linguistic traditions, uncertainty still remains on the best way to annotate them for Natural Language Processing (NLP) purposes. This paper reviews the evolution of the concept of auxiliary verbs to gather insights into forms of representing them in an annotation scheme and raises some issues with a view to leveraging the potential afforded by them in different NLP tasks. Using Brazilian Portuguese as an instance language and Universal Dependencies (UD) as annotation model, we argue for (i) annotating inflected verbs as heads, (ii) annotating auxiliary interdependence in an auxiliation chain; and (iii) adopting a more consistent treatment of auxiliaries to encompass tense, aspect, modality and voice in auxiliation chains. We further propose auxiliary type as a feature to be annotated which can be easily implemented in existing and new treebanks with substantial gains in enriching the information that can be extracted for different NLP applications. |
