distilbert-base-multilingual-cased-definitions_ner is a NER model (token classification) in the scientific domain in German, finetuned from the model distilbert-base-multilingual-cased. It was trained using a custom annotated dataset of around 10,000 training and 2,000 test examples containing definition- and non-definition-related sentences from wikipedia articles in german.

The model is specifically designed to recognize and classify components of definitions, using the following entity labels:

DF: Definiendum (the term being defined)
VF: Definitor (the verb or phrase introducing the definition)
GF: Definiens (the explanation or meaning)

Training was conducted using a standard NER objective. The model achieves an F1 score of approximately 81% on the evaluation set.

Here are the overall final metrics on the test dataset after 5 epochs of training:

f1: 0.812455003599712
precision: 0.8076097328244275
recall: 0.8173587638821825
loss: 0.329479843378067
