An Empirical Analysis of Task Relations in the Multi-Task Annotation of an {A}rabizi Corpus

In this study, we deal with the design of computational-linguistic resources and strategies for the analysis of under-resourced languages. In particular, we present empirical analyses aiming at identifying the best path to semi-utomatically annotate a dialectal Arabic corpus via a neural multi-task architecture. Such an architecture is
used to automatically generate several levels of linguistic annotation which can be evaluated by comparison with the gold annotation. Changing the order in which annotations are produced can have an impact on the quantitative results. Through multiple sets of experiments we show how to get the best performances with this methodology.
