Multilingual segmentation based on neural networks and pre-trained word embeddings

The DISPRT 2019 workshop has organized a shared task aiming to identify cross-formalism and multilingual discourse segments.
Elementary Discourse Units (EDUs) are quite similar across different theories. Segmentation is the very first stage on the way of rhetorical annotation. Still, each annotation project adopted several decisions with consequences not only on the annotation of the relational discourse structure but also at the segmentation stage.
In this shared task, we have employed pre-trained word embeddings, neural networks (BiLSTM+CRF) to perform the segmentation.

EusDisParser: improving an under-resourced discourse parser with cross-lingual data

Development of discourse parsers to annotate the relational discourse structure of a text is crucial for many downstream tasks.
However, most of the existing work focuses on English, assuming a quite large dataset.
Discourse data have been annotated for Basque, but training a system on these data is challenging since the corpus is very small.
In this paper, we create the first parser based on RST for Basque, and we investigate the use of data in another language to improve the performance of a Basque discourse parser.

Euskarazko denbora-egituren azterketa eta corpusaren sorrera / Analysis of Basque temporal constructions and the creation of a corpus

Ikerketa-lan honetan euskarazko denbora-informazioaren prozesamenduan lehen urratsak egin ditugu. Horretarako, beste hizkuntzetan egin diren lanetan eta euskarazko denbora-egituren analisi linguistikoan oinarritu gara. Informazio hori baliatuta, euskarazko denbora-egiturak automatikoki tratatzeko ezaugarri linguistiko esanguratsuenak identifikatu ditugu eta horiek kodetzeko EusTimeML markaketa-lengoaia sortu dugu. Era berean, EusTimeMLri jarraituta denbora-informazioa eskuz etiketatuta duen EusTimeBank corpusa sortu dugu.
