No Name Thai NER

Compact Thai token-classification model optimized for fast named-entity recognition (NER) and practical medical-text deidentification. This checkpoint was trained for robust entity detection on Thai clinical and conversational text and is intended for use in context-preserving anonymization pipelines.

At Looloo Health, we're passionate about making healthcare more accessible and affordable for everyone. The model is a core component of our AI Medical Scribe, PresScribe, where it helps ensure patient privacy through automated de-identification. We believe that unlocking the potential of clinical data is key to this goal, and we're excited to share our work with the community.

Features

• Detects common sensitive entity types found in medical text (names, phone numbers, IDs, addresses, dates, etc.).
• Lightweight and fast to run on CPUs with the Hugging Face transformers pipeline.
• Designed to be used as part of a deidentification workflow (post-processing recommended to merge token-level spans).
• Trained on a comprehensive synthetic dataset of over 300,000 samples, ensuring it is robust and generalizable.
• On our internal test set, we achieved over 95% accuracy for our specific use case.

Supported entity labels

• PERSON
• PHONE
• EMAIL
• ADDRESS (sometimes labelled as LOCATION)
• DATE
• NATIONAL_ID
• HOSPITAL_IDS

Quick start

Install minimal dependencies:

pip install -U transformers torch

Load and run the model with Hugging Face pipelines:

from transformers import pipeline

ner = pipeline("token-classification", model="loolootech/no-name-ner-th", device=-1)
text = "คุณสมชายเป็นอะไรมาครับวันนี้ อ๋อวันนี้ปวดตับครับ งั้นวันนี้หมอขอตรวจละเอียดหน่อยนะ ได้เลยครับน้องมาร์ค"
results = ner(text)
print(results)

Notes on post-processing (more details on our example notebook)

• The pipeline returns token-level predictions (B-/I- style). For redaction or anonymization you should merge adjacent tokens with the same label to form full spans before replacing with entity-specific redaction tokens (e.g. [PERSON], [PHONE]).
• When redacting, replace spans from right-to-left or rebuild the output string from slices to avoid offset shifts.

Disclaimer

• This model is intended as an assistive tool for de-identification. It is not a substitute for professional, legal, or medical advice.

• Users are fully responsible for ensuring compliance with applicable privacy, legal, and regulatory requirements.

• While efforts have been made to improve accuracy, no automated system is 100% reliable. We strongly recommend implementing a regular human review process to validate outputs.

Acknowledgement

We extend our gratitude to the PhayaThaiBERT team and Pavarissy/phayathaibert-thainer for providing the initial checkpoint for our model, which served as a crucial starting point. We also acknowledge PyThaiNLP for their invaluable contribution of the thainer-corpus-v2 dataset, which was essential for training and evaluation.
