newsintel-event-type

Multi-label event-type router: accident / disaster / crime (a document may fire several).

Part of NewsIntel AI — a CPU-deployable, LLM-free pipeline that extracts structured public-safety events (accidents, disasters, crimes) from Bangladeshi news in Bengali and English. This model is stage 2 · router — accident/disaster/crime of that chain:

document → relevance gate → event-type router → evidence selection
         → NER → relation extraction → knowledge graph → structured event JSON

Model details

Labels

• —accident
• —disaster
• —crime

Thresholds

• —accident: 0.675
• —disaster: 0.75
• —crime: 0.55

Decision rule

p = sigmoid(logits); fired[i] = p[i] >= thresholds[labels[i]]

These values also ship machine-readable in model_manifest.json, so a serving process can consume the model without hardcoding anything.

Evaluation

Usage

from huggingface_hub import snapshot_download
import onnxruntime as ort, numpy as np
from transformers import AutoTokenizer

d = snapshot_download("saidylive/newsintel-event-type", revision="cf651b4757647",
                      allow_patterns=["model_int8.onnx", "*.json", "*.model"])
tok = AutoTokenizer.from_pretrained(d)
sess = ort.InferenceSession(f"{d}/model_int8.onnx", providers=["CPUExecutionProvider"])

enc = tok("সাভারে বাস-ট্রাকের সংঘর্ষে নিহত ২", return_tensors="np")
logits = sess.run(None, {k: v for k, v in enc.items()
                         if k in {i.name for i in sess.get_inputs()}})[0]
# decision rule (from model_manifest.json):
#   p = sigmoid(logits); fired[i] = p[i] >= thresholds[labels[i]]

Training data & provenance

Trained on the `bd_eng_news_daily` Kaggle corpus of Bangladeshi news (~713k articles, ~96% Bengali by character ratio). Labels are silver, not human-annotated: a teacher LLM produced structured event annotations, which were distilled into these small models. No manual annotation was performed at any stage.

This matters for how you read the metrics: they measure agreement with LLM-generated labels, not with human ground truth. There is no human-labelled evaluation set.

Limitations & bias

• —Silver labels cap the ceiling. Systematic teacher-LLM errors are inherited.
• —Domain-specific. Tuned to Bangladeshi public-safety news; expect degradation on other domains, regions, or registers.
• —Opinion pieces leak through. Editorials and foreign wire stories are sometimes classified as events by the upstream gate/router.
• —Entity noise. NER tags some generic Bengali nouns (e.g. রাজধানীর "of the capital", সদর "HQ") as locations.
• —No calibration. Confidence-style outputs are uncalibrated; do not read them as probabilities of correctness.
• —INT8 quantization trades a little accuracy for ~4× size reduction and CPU speed.
• —Not for high-stakes use. Casualty counts and event classifications are unverified model output and must not be used for emergency response, journalism, or policy without human review.
