Croatian translation of SciDCC, a collection of 11,539 popular-science news articles from ScienceDaily's earth, climate, plant and animal sections.
Source
Original dataset: SciDCC, introduced in the paper "NeuralNERE: Neural Named Entity Relationship Extraction for End-to-End Climate Change Knowledge Graph Construction" (Mishra and Mittal, 2021).
Translation
The English articles were machine translated into Croatian with Mistral-Small-3.2-24B-Instruct-2506, an instruction-tuned model with 24 billion parameters, run locally in quantised form. The title, summary and body of each article were translated separately. The translations were not manually reviewed.
On a label-stratified sample of 90 documents, the translation reaches a mean COMET-Kiwi score of 0.842 and a mean XCOMET-XL score of 0.828. Article bodies score slightly below titles and summaries.
