SomaliWeb v1: A Quality-Filtered Somali Web Corpus with a Matched Tokenizer and a Public Language-Identification Benchmark
The paper introduces SomaliWeb v1, a new quality-filtered Somali web corpus comprising 819,322 documents and ~303M tokens. It includes a matched BPE-16K tokenizer and the first public Somali language-identification benchmark. This initiative addresses the critical gap in documented, high-quality resources for Somali NLP, revealing significant quality defects in existing multilingual datasets.

SomaliWeb v1 details a six-stage pipeline including byte-exact deduplication, normalization, language identification, near-duplicate removal, and quality filtering. This rigorous process ensures a high-quality, clean dataset crucial for robust AI model training.
Key Insight: Addressing quality defects upfront reduces downstream training costs.
A custom BPE-16K tokenizer trained on SomaliWeb v1 proves 40.2% more token-efficient than GPT-4's cl100k_base on Somali devtest. This directly translates to lower inference costs and more efficient model representations for Somali.
Implication: Optimized tokenization is vital for low-resource language efficiency.
The study provides the first public Somali-specific benchmark for leading language identifiers (langdetect, GlotLID v3, fastText lid.176). Surprisingly, langdetect outperformed newer models in Somali F1 score, highlighting the need for specific language evaluations.
Recommendation: Validate LID tools for target low-resource languages.

Optimizing AI for Low-Resource Languages
A global content platform struggled with the high cost and low accuracy of AI models for Somali, due to fragmented and low-quality training data from existing multilingual sources. By adopting the SomaliWeb v1 corpus and its custom tokenizer, they achieved a 40.2% reduction in token count for Somali text, leading to significant cost savings in inference and a marked improvement in content moderation accuracy due to higher quality training data.
This case demonstrates how dedicated, quality-filtered corpora for low-resource languages can unlock efficient and effective AI applications, moving beyond generic multilingual datasets.
