This library builds on ideas and patterns from several open-source
projects and academic research.

## Prior Art

### lopdf (MIT)

- Bounded structural parsing for the PDF inspection contract
- Copyright (c) 2016 Junfeng Liu
- https://github.com/J-F-Liu/lopdf

### Microsoft Presidio (MIT)

- Context-word boosting architecture
- Structured PII pattern design (IBAN, phone, email)
- Unicode/IDN domain-label handling and validation-first phone matching,
  adapted from pinned commit `efc775903f55c3e50e12b5902ec2699c2e52fdf7`
- Internationalized domains use bounded RFC-like label shapes and accept
  decomposed Unicode combining marks. Punycode receives shape validation only,
  not complete IDNA validation.
- Operator concept (replace vs redact)
- https://github.com/microsoft/presidio/tree/efc775903f55c3e50e12b5902ec2699c2e52fdf7

### Scrubadub (Apache 2.0)

- RFC-style email local-part symbol coverage and conservative written
  `at`/`dot` email grammar
- Validation-first phone matching principles
- Adapted from pinned commit `53772cbef417da290d25c95373031f786ab3b5c6`
- https://github.com/LeapBeyond/scrubadub/tree/53772cbef417da290d25c95373031f786ab3b5c6

### GLiNER / GLiNER.js (MIT)

- Span-level and token-level NER via ONNX
- The `gliner/` module is an original implementation informed
  by the GLiNER architecture (arXiv:2311.08526)
- Processor and decoder logic reimplemented from scratch
- https://github.com/urchade/GLiNER

### NameTag / MorphoDiTa (ÚFAL, Charles University)

- Czech NER and morphological analysis research
- Czech name declension suffix patterns
- https://ufal.mff.cuni.cz/nametag
- https://ufal.mff.cuni.cz/morphodita

### Text Anonymization Benchmark (NorskRegnesentral, MIT)
