SpanMarker for GermEval 2014 NER

This is a SpanMarker model that was fine-tuned on the GermEval 2014 NER Dataset.

The GermEval 2014 NER Shared Task builds on a new dataset with German Named Entity annotation with the following properties: The data was sampled from German Wikipedia and News Corpora as a collection of citations. The dataset covers over 31,000 sentences corresponding to over 590,000 tokens. The NER annotation uses the NoSta-D guidelines, which extend the Tübingen Treebank guidelines, using four main NER categories with sub-structure, and annotating embeddings among NEs such as [ORG FC Kickers [LOC Darmstadt]].

12 classes of Named Entites are annotated and must be recognized: four main classes PERson, LOCation, ORGanisation, and OTHer and their subclasses by introducing two fine-grained labels: -deriv marks derivations from NEs such as "englisch" (“English”), and -part marks compounds including a NE as a subsequence deutschlandweit (“Germany-wide”).


We use the same hyper-parameters as used in the "German's Next Language Model" paper using the GWLMS BERT model as backbone.

Evaluation is performed with SpanMarkers internal evaluation code that uses seqeval.

We fine-tune 5 models and upload the model with best F1-Score on development set. Results on development set are in brackets:

Model Run 1 Run 2 Run 3 Run 4 Run 5 Avg.
GWLMS BERT (87.27) / 87.28 (87.20) / 87.42 (88.05) / 87.68 (88.25) / 87.59 (88.47) / 87.45 (87.85) / 87.48

The best model achieves a final test score of 87.45%.

Scripts for training and evaluation are also available.


The fine-tuned model can be used like:

from span_marker import SpanMarkerModel

# Download from the 🤗 Hub
model = SpanMarkerModel.from_pretrained("stefan-it/span-marker-bert-germeval14")

# Run inference
entities = model.predict("Jürgen Schmidhuber studierte ab 1983 Informatik und Mathematik an der TU München .")
