Extensions

On each span span that match, the following attributes are available:

span._.detailed_status: set to None

Examples

import edsnlp, edsnlp.pipes as eds

nlp = edsnlp.blank("eds")
nlp.add_pipe(eds.sentences())
nlp.add_pipe(
    eds.normalizer(
        accents=True,
        lowercase=True,
        quotes=True,
        spaces=True,
        pollution=dict(
            information=True,

            coding=True,
            footer=True,
        ),
    ),
)
nlp.add_pipe(eds.leukemia())

Below are a few examples:

text = "Sydrome myéloprolifératif"
doc = nlp(text)
spans = doc.spans["leukemia"]

spans
# Out: [myéloprolifératif]

text = "Sydrome myéloprolifératif bénin"
doc = nlp(text)
spans = doc.spans["leukemia"]

spans
# Out: []

text = "Patient atteint d'une LAM"
doc = nlp(text)
spans = doc.spans["leukemia"]

spans
# Out: [LAM]

text = "Une maladie de Vaquez"
doc = nlp(text)
spans = doc.spans["leukemia"]

spans
# Out: [Vaquez]
