sosa-pii-ner-sg-v1.1.0

Singapore regional PII span detection model. Fine-tune of urchade/gliner_large-v2.1 on synthetic Singapore-context PII data. Deployed in SOSA DevOps as the SG-region sidecar NER uplift layer.

Labels

Label	Format	Description
sg_nric_fin	[STFG]XXXXXXX[A-Z]	Singapore NRIC/FIN (national ID / foreigner ID)
sg_uen	XXXXXXXXX[A-Z] (9-10 chars)	Singapore Unique Entity Number (business registry)
sg_phone_local	+65 XXXX XXXX	Singapore phone numbers
sg_health_hrn	SGH-YYYY-NNNNNN or numeric	Singapore hospital record numbers

Global labels also detected: email, phone_e164, credit_card, passport_generic, ipv4_public

Training

• Base model: urchade/gliner_large-v2.1 (Apache 2.0)
• Hardware: RunPod A40 48GB, EU-SE-1
• Steps: 10,000 | Batch: 8 | Wall time: ~43 min
• Dataset: D-SG-2 + D-SG-2b merged — 1,299 effective positives
• Internal checkpoint: sosa-pii-ner-sg-v0.2.0
• Weights SHA-256: 32022cf0faa626cd23d0aa5c2a46a975cca488d1feb26cd518ee0eb72520e418

Training history (runs to reach v1.1.0)

Run	Dataset	NRIC F1	UEN F1	Status
v0.1.0 (v1.0.0)	D-SG-1	0.9524	0.7143	PASS — shipped as v1.0.0
v0.2.0	+D-SG-2b	0.9841	0.7333	PASS — v1.1.0

D-SG-2b fixes: UEN+phone, UEN+HRN, NRIC+HRN multi-entity co-occurrence gaps (stress test failures SG-P11, SG-P13).

Known Limitations

• sg_uen precision 0.5789 — 8 FP present (postal codes, reference numbers of UEN shape)
• sg_health_hrn precision 0.5172 — 28 FP (alphanumeric codes confused with HRN format)
• sg_phone_local precision 0.6486 — 39 FP (foreign numbers, short sequences)
• Precision gaps on UEN and HRN are P1/P2 — targeted for D-SG-3 in a future slice

Integration (SOSA DevOps)

Loaded by sidecar when active_layers includes country:SG. Spans merged into Rust scrubber output via merge_sidecar_spans. Not a replacement for the always-on Rust regex layer — contextual uplift only.
