The paper introduces a large corpus of about 160,000 Brazilian Portuguese financial news articles to support Natural Language Processing research in this domain. It presents initial benchmarks for a weakly supervised multi‑class classification task using semantic similarity, evaluating cosine similarity, K‑Nearest Neighbors (KNN), and FAISS‑based nearest‑neighbor search with multilingual embeddings. Results show that KNN performs best on manually labeled data (47.3% accuracy, 31.9% F1), while LLM‑annotated data yields similar accuracy but much lower F1 scores due to label imbalance and noise.

The paper introduces a multilingual, multi-functional framework for disambiguating funder names in scientific publications, using a training dataset that merges the Research Organization Registry with Web of Science and Crossref Open Funder Registry data. By applying multi-task learning with contrastive and multiple negatives ranking losses, the authors fine‑tune open‑weight embedding models from the Sentence Transformer, Gemma, and Qwen3 families, achieving over 90% accuracy in matching Web of Science funder names to ROR identifiers and surpassing general‑purpose LLMs by more than 0.1. For funders not present in ROR, a similarity network is constructed to identify clusters, and the study discusses challenges related to smaller and non‑English‑speaking funders.

The paper investigates cross‑lingual transfer for sequential sentence classification (SSC) in research papers, focusing on 13 non‑English languages. Experiments show that linguistic proximity does not reliably predict transfer success, whereas structural similarity in rhetorical organization—particularly label distribution similarity—correlates positively with performance. The authors introduce three generative‑model methods that exploit structural cues, achieving parity with strong encoder baselines on‑domain and outperforming them when transferring to unseen languages.
