EDS-NLP is a collaborative NLP framework that aims primarily at extracting information from French clinical notes. At its core, it is a collection of components or pipes, either rule-based functions or deep learning modules. These components are organized into a novel efficient and modular pipeline system, built for hybrid and multitask models. We use spaCy to represent documents and their annotations, and Pytorch as a deep-learning backend for trainable components.
EDS-NLP is versatile and can be used on any textual document. The rule-based components are fully compatible with spaCy's components, and vice versa. This library is a product of collaborative effort, and we encourage further contributions to enhance its capabilities.
Check out our interactive demo !
You can install EDS-NLP via pip
. We recommend pinning the library version in your projects, or use a strict package manager like Poetry.
pip install edsnlp==0.13.0
or if you want to use the trainable components (using pytorch)
pip install "edsnlp[ml]==0.13.0"
Once you've installed the library, let's begin with a very simple example that extracts mentions of COVID19 in a text, and detects whether they are negated.
import edsnlp, edsnlp.pipes as eds
nlp = edsnlp.blank("eds")
terms = dict(
covid=["covid", "coronavirus"],
)
# Split the documents into sentences, this isneeded for negation detection
nlp.add_pipe(eds.sentences())
# Matcher component
nlp.add_pipe(eds.matcher(terms=terms))
# Negation detection (we also support spacy-like API !)
nlp.add_pipe("eds.negation")
# Process your text in one call !
doc = nlp("Le patient n'est pas atteint de covid")
doc.ents
# Out: (covid,)
doc.ents[0]._.negation
# Out: True
Go to the documentation for more information.
The performances of an extraction pipeline may depend on the population and documents that are considered.
