Domain: Informal & Social Media Text
Training Date: 2026-02-26

🏷️ Supported Entity Labels

This model detects the following entity types:

Label	Description
PER	Person
ORG	Organization
NOR	Political Organization
GPE	Geopolitical Entity
LOC	Location
FAC	Facility
LAW	Legal Entity (e.g., Undang-Undang)
EVT	Event
WOA	Work of Art

Tagging Scheme

BIO tagging format is used:

B-XXX → Beginning of an entity
I-XXX → Inside an entity
O → Outside any entity

🚀 Usage

Quick Inference (Hugging Face Pipeline)

python

from transformers import pipeline

ner = pipeline(
    "token-classification",
    model="nahiar/xlm-roberta-ner",
    aggregation_strategy="simple"
)

text_id = "Jokowi menghadiri World Economic Forum di Davos."
text_en = "Apple is opening a new office in Jakarta next month."

print(ner(text_id))
print(ner(text_en))

Aggregation Strategy Notes

"simple" → Recommended (merges subword tokens)
"first" → Uses first token representation
"average" → Averages token scores
"max" → Takes maximum token score

🎯 Intended Use Cases

Social media Named Entity Recognition
Comment & post filtering
Content moderation assistance
Political monitoring
Brand & organization tracking
Multilingual content intelligence systems

⚠️ Limitations

Supports only the defined entity set: NOR, GPE, PER, ORG, EVT, LOC, LAW, FAC, WOA
Not optimized for:
- Formal academic/legal documents
- Extremely short or ambiguous messages
- Heavy slang or sarcastic expressions
Performance may degrade on highly code-mixed sentences
The model may inherit bias from training data

⚖️ Ethical Considerations

This model may reflect demographic, geopolitical, or cultural biases present in the training dataset.

It is not intended to replace human judgment in high-risk or sensitive decision-making systems.

Human-in-the-loop review is strongly recommended for moderation or governance-related deployments.

🖥️ Hardware Recommendations

Recommended: GPU (≥ 8GB VRAM) for optimal performance
CPU inference supported but slower
Compatible with FP16 mixed precision for faster inference
