# Riidact NER — multilingual names & places
Token-classification model (PER / LOC / ORG) powering
[Riidact](https://riidact.com)'s on-device name detection. Runs
in the browser via transformers.js + ONNX Runtime; the quantized weights
(`onnx/model_quantized.onnx`, ~178 MB) are what ships.
## License
These fine-tuned weights are released under **CC-BY-NC-4.0**: free to use,
share, and adapt for **non-commercial** purposes, with attribution. For commercial use, contact Riidact.
The MIT-licensed base model (`numind/NuNER-multilingual-v0.1`) is unaffected
and remains available under its own terms — see the NOTICE below. The
non-commercial terms apply to this fine-tune, not to the underlying base.
## Coverage
Fine-tuned on 103 languages; **88 are certified** by a two-tier benchmark:
realistic-sentence recall with a zero-false-positive corpus (72 languages),
plus held-out WikiANN validation at PER F1 ≥ 0.80 (84 languages).
## Lineage
- **Backbone:** [numind/NuNER-multilingual-v0.1](https://huggingface.co/numind/NuNER-multilingual-v0.1) (MIT)
- **Training data:** WikiANN (Wikipedia-derived, PAN-X annotations), 501k
sentences across 103 languages, plus a small synthetic supplement of
conversational name shapes (honorific patterns) that Wikipedia-derived
data lacks.
## Recommended inference floors
Span mean confidence, per entity: PER ≥ 0.55, LOC ≥ 0.9 (precision-first;
calibrated against the benchmark corpus above).
