SpanMarker for uncased Named Entity Recognition

This is a SpanMarker model that can be used for Named Entity Recognition. In particular, this SpanMarker model uses bert-base-uncased as the underlying encoder. See train.py for the training script. It is trained on P3ps/Cross_ner, which I believe is a variant of DFKI-SLT/cross_ner that merged the validation set into the training set and applied deduplication.

Is your data always capitalized correctly? Then consider using the cased variant of this model instead for better performance: tomaarsen/span-marker-bert-base-cross-ner.

Usage

To use this model for inference, first install the span_marker library:

pip install span_marker

You can then run inference with this model like so:

from span_marker import SpanMarkerModel

# Download from the 🤗 Hub
model = SpanMarkerModel.from_pretrained("tomaarsen/span-marker-bert-base-uncased-cross-ner")
# Run inference
entities = model.predict("amelia earhart flew her single engine lockheed vega 5b across the atlantic to paris.")

See the SpanMarker repository for documentation and additional information on this library.
