Through this, you can take advantage of the advanced Named Entity Recognition capabilities of SpanMarker within the familiar and powerful spaCy framework.\n\nBy default, the `span_marker` pipeline component uses a [SpanMarker model using RoBERTa-large trained on OntoNotes v5.0](https://huggingface.co/tomaarsen/span-marker-roberta-large-ontonotes5). This model reaches a competitive 91.54 F1, notably higher than the [85.5 and 89.8 F1](https://spacy.io/usage/facts-figures#section-benchmarks) from `en_core_web_lg` and `en_core_web_trf`, respectively. A short head-to-head between this SpanMarker model and the `trf` spaCy model has been posted [here](https://github.com/tomaarsen/SpanMarkerNER/pull/12).\n\nAdditionally, see [here](https://tomaarsen.github.io/SpanMarkerNER/notebooks/spacy_integration.html) for documentation on using SpanMarker with spaCy.",
