IrishCore-GlobalPointer-ContextPII-135M-v1-rc6

IrishCore-GlobalPointer-ContextPII-135M-v1-rc6 is the current expanded-label raw-only PII masking release for Irish public-sector, HSE, and citizen-support flows.

It keeps the same DistilBERT-size GlobalPointer span extractor family as temsa/IrishCore-GlobalPointer-ContextPII-135M-v1-rc5, but ships a stronger bundled decoder for broader Irish contextual masking.

Context labels served by this line:

• STREET_ADDRESS
• CITY
• COUNTY
• DATE_OF_BIRTH
• AGE

Core labels retained:

• PPSN
• POSTCODE
• PHONE_NUMBER
• EMAIL
• PASSPORT_NUMBER
• ACCOUNT_NUMBER
• BANK_ROUTING_NUMBER
• SWIFT_BIC
• CREDIT_DEBIT_CARD
• FIRST_NAME
• LAST_NAME

Positioning

rc6 is a decoder-hardening release over rc5.

• weights unchanged
• ONNX graph unchanged
• no external scanner or validator added
• deployment path still single-pass span extraction plus deterministic [PII:LABEL] replacement

What changed in rc6:

• broader Irish city/county coverage for forms such as Sligo / Sligeach, Letterkenny / Leitir Ceanainn, Castlebar / Caisleán an Bharraigh, Wexford / Loch Garman, Navan / An Uaimh, and Dundalk / Dún Dealgan
• overlapping county tails like County Sligo and Contae Dhún na nGall now stay COUNTY instead of collapsing into FIRST_NAME
• cue-led address blocks such as Address: 2 Harbour View and Seoladh: 2 Radharc an Chuain now recover full STREET_ADDRESS spans even without a street-suffix token
• Fón: cues now recover callback numbers in assistant answers when the model under-predicts the phone span
• the new globalpointer_location_coverage_v1 suite is 1.0000 on both full and q8 paths

Use this release when you need broader masking for Irish gov / HSE / citizen-support text, including user turns and assistant answers that contain:

• personal address fragments
• city / county
• date of birth
• age
• official callback numbers or public-service mailbox emails that still need masking in assistant output

If you only need the narrower Irish-core structured label set and want maximum CPU throughput, temsa/IrishCore-GlobalPointer-135M-v1-rc4 remains the faster option.

Architecture

• base encoder: OpenMed/OpenMed-PII-mLiteClinical-Base-135M-v1
• extractor head: GlobalPointer-style typed span matrix
• runtime: single-pass span extraction
• output policy: deterministic bracket masking, for example [PII:PPSN]
• deployment target: ONNX Runtime CPU with dynamic q8 per-channel quantization

This is not a generative model and does not rewrite text. It predicts typed spans and the provided inference scripts replace them with [PII:LABEL] placeholders.

Decoder Policy

The serving path is still raw-only in the sense that there is no external scanner or validator service. The repo does include bundled decoder repairs for highly structured or contextual spans:

• PPSN normalization and overlap repair
• passport cue-based repair
• contextual date-of-birth repair
• full-email recovery
• contextual phone recovery, including Fón: cues
• Eircode recovery
• contextual street-address recovery, including cue-led suffixless address blocks
• explicit county phrase recovery with county-over-name overlap cleanup

These repairs live inside common.py and are part of the published inference path.

Comparison

Tradeoff:

• this expanded-label line is materially better on contextual Irish masking tasks, especially broader county/city/address coverage
• it is slower than the core-only GlobalPointer line on CPU because it carries a broader label inventory and more decoder work

Evaluation Notes

Additional q8 release checks shipped in this repo:

• eval/q8_irish_numeric_qafix_v2.json: numeric false-positive guardrail suite, 1.0000 F1
• eval/q8_irish_gov_chatbot_redteam_user_v2.json: user-turn split, 1.0000 F1
• eval/q8_irish_gov_chatbot_redteam_assistant_v2.json: assistant-turn split, 0.9677 F1
• eval/q8_globalpointer_context_redteam_v1.json: contextual hardening suite for apartment-prefix street addresses, explicit County/Contae forms, and public-office address blocks, 1.0000 F1
• eval/q8_globalpointer_location_coverage_v1.json: broader Irish city/county/address coverage suite, 1.0000 F1 in rc6 versus 0.5517 in the public rc5 bundle

The remaining assistant split miss is a policy mismatch on a public office address/city block: this contextual line still masks Kennedy Avenue, Carlow while the legacy assistant v2 gold only scores postcode and phone in that row.

Other notes:

• globalpointer_demographic_patch_v2_test is the corrected held-out benchmark. The earlier v1 demographic patch contained invalid synthetic Eircodes in some rows.
• irish_gov_contact_policy_v1 is the policy-aligned assistant-output benchmark for this release.
• globalpointer_context_redteam_v1 is the contextual hardening benchmark for apartment-prefix addresses, explicit county phrases, and assistant public-office blocks.
• globalpointer_location_coverage_v1 is the broader Irish location benchmark for county-over-name overlap, address-block recovery, and additional English / Irish Gaelic city-county pairs.
• The legacy irish_gov_chatbot_redteam_v2 negatives still assume some public assistant contact details should not be masked. That assumption does not match this release's target policy.

Usage

Full checkpoint:

python3 inference_mask.py --model temsa/IrishCore-GlobalPointer-ContextPII-135M-v1-rc6 --text "I live at 14 Main Street, Dublin, Co. Dublin, D02 XY45 and my date of birth is 03/02/1991."

ONNX q8:

python3 inference_mask_onnx.py --model temsa/IrishCore-GlobalPointer-ContextPII-135M-v1-rc6 --text "Sampla d'ionad poiblí: Seoladh: 2 Radharc an Chuain, Loch Garman, Contae Loch Garman, Y35 XY12. Fón: 053 912 3456."

Expected masking style:

I live at [PII:STREET_ADDRESS], [PII:CITY], [PII:COUNTY], [PII:POSTCODE] and my date of birth is [PII:DATE_OF_BIRTH].

Limitations

• This release is Irish-first. Multilingual overall precision is still pulled down by extra name detections outside the primary Irish target domain.
• The decoder deliberately prefers recall on structured Irish identifiers and contextual Irish location masking. If you need a stricter non-Irish name policy, test on your own corpora before promoting beyond rc.

Portfolio Comparison

Updated: 2026-03-16.

Use this section for the fastest public comparison across the temsa PII masking portfolio.

• The first core table only includes public checkpoints that ship both comparable q8 accuracy and q8 CPU throughput.
• The first PPSN table only includes public artifacts that ship comparable PPSN accuracy and CPU throughput.
• Missing cells in the archive tables mean the older release did not ship that metric in its public bundle.
• DiffMask rows use the reconciled clean_single_pass harness that matches the deployed runtime.
• GlobalPointer rows use the public raw-only span-matrix release bundle and its packaged q8 ONNX artifact.
• The same content is shipped as PORTFOLIO_COMPARISON.md inside each public model repo.
