normaere-model

Transformer-based seq2seq normalizer for Middle High German (MHG) text, fine-tuned from google/mt5-base.

Model Details

• Base Model: google/mt5-base (580M parameters)
• Architecture: MT5ForConditionalGeneration (encoder-decoder)
• Precision: FP16
• Max Sequence Length: 512 tokens
• Vocabulary Size: 250,117 (augmented with medieval abbreviation characters)

Intended Uses

Normalizes Middle High German texts (ca. 1050–1500) according to the standards of the Referenzkorpus Mittelhochdeutsch (ReM):

• Solves common abbreviations
• Splits off and expands common pro- and enclitics
• Applies editorial post-processing

Training Data

Fine-tuned on the Referenzkorpus Mittelhochdeutsch (ReM), Version 2.1.

Usage

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained("JonasHermann/normaere-model")
model = AutoModelForSeq2SeqLM.from_pretrained("JonasHermann/normaere-model")

input_text = "die stete wârheit"
inputs = tokenizer(input_text, return_tensors="pt")
outputs = model.generate(**inputs)
result = tokenizer.decode(outputs[0], skip_special_tokens=True)
