SOLD - A Benchmark for Sinhala Offensive Language Identification
In this repository, we introduce the {S}inhala {O}ffensive {L}anguage {D}ataset (SOLD) and present multiple experiments on this dataset. SOLD is a manually annotated dataset containing 10,000 posts from Twitter annotated as offensive and not offensive at both sentence-level and token-level. SOLD is the largest offensive language dataset compiled for Sinhala. We also introduce SemiSOLD, a larger dataset containing more… See the full description on the dataset page: https://huggingface.co/datasets/sinhala-nlp/SOLD.sinhala_storiesopenslr-sinhala-asrsinhala-openslr-111hsinhala_sentences_rawopenslr-sinhala-asr-normlarge-sinhala-asr-datasetsinhala_30m

Serendib LLM CPT Sinhala Corpus
A large-scale, deduplicated, quality-filtered Sinhala plain-text corpus built for
Continual Pre-Training (CPT) of large language models. This dataset was used to adapt
Meta-LLaMA-3-8B to the Sinhala language domain as part of the
Serendib LLM Honours Degree Research Project
at the University of Central Lancashire (UCLan), 2025–2026.
This is one of the largest openly published Sinhala NLP corpora available, containing
23,449,223 training documents… See the full description on the dataset page: https://huggingface.co/datasets/Chamaka8/serendip-cpt-sinhala.named-entity-recognitionNSINA-Categories
