MobAnon NER Model

German Named Entity Recognition model for the MobAnon document anonymization app. Fine-tuned from deepset/gelectra-large on GermEval14 for on-device inference.

Model Details

Property	Value
Base model	deepset/gelectra-large
Training data	GermEval14 (German NER)
Format	TensorFlow Lite (float16 quantized)
Size	~638 MB
Test F1	~87-89%
Max sequence length	128 tokens

Entity Types

The model detects four semantic entity types using BIO tagging:

Entity	Examples
PERSON	Max Mustermann, Dr. Schmidt
ORGANIZATION	Deutsche Bank, Bundesgerichtshof
LOCATION	Frankfurt, Deutschland, Berliner Str.
MISC	Events, dates, other named entities

MobAnon supplements these with regex-based detection for structured entities (email, phone, IBAN, identifiers).

Usage

This model is downloaded automatically by the MobAnon app on first use. No manual setup required.
