• Abstract: This paper presents the first publicly available version of the Carolina Corpus and discusses its future directions. Carolina is a large open corpus of Brazilian Portuguese texts under construction using web-as-corpus methodology enhanced with provenance, typology, versioning, and text integrality. The corpus aims at being used both as a reliable source for research in Linguistics and as an important resource for Computer Science research on language models, contributing towards removing Portuguese from the set of low-resource languages. Here we present the construction of the corpus methodology, comparing it with other existing methodologies, as well as the corpus current state: Carolina's first public version has $653,322,577$ tokens, distributed over $7$ broad types. Each text is annotated with several different metadata categories in its header, which we developed using TEI annotation standards. We also present ongoing derivative works and invite NLP researchers to contribute with their own.

  RAAMove is a comprehensive corpus dedicated to the annotation of move structures in Research Article (RA) abstracts. The corpus is constructed through two stages: first, expert annotators manually annotate high-quality data; then, based on the human-annotated data, a BERT-based model is employed for automatic annotation. The result is a large-scale and high-quality corpus comprising 33,988 annotated instances.
