An Expanded Massive Multilingual Dataset for High-Performance Language Technologies (HPLT)

ACL 2025long

Training state-of-the-art large language models requires vast amounts of clean and diverse textual data. However, building suitable multilingual datasets remains a challenge. In this work, we present HPLT v2, a collection of high-quality multilingual monolingual and parallel corpora, extending prior…

We argue that this division has become counterproductive and propose a new u…
