Date detection

text = (
    "Le patient est arrivé le 23 août (23/08/2021). "
    "Il dit avoir eu mal au ventre hier. "
    "L'année dernière, on lui avait prescrit du doliprane."
)

nlp = spacy.blank('fr')

doc = nlp(text)

dates = Dates(
    nlp,
    absolute=terms.absolute,
    relative=terms.relative,
    no_year=terms.no_year,
)

dates(doc)

doc.spans

print(f"{'expression':<20}  label")
print(f"{'----------':<20}  -----")

for span in doc.spans['dates']:
    print(f"{span.text:<20}  {span._.date}")

Lorsque la date du document n'est pas connue, le label des dates relatives (hier, il y a quinze jours, etc) devient TD±<nb-de-jours>

Si on renseigne l'extension note_datetime :

doc._.note_datetime = datetime(2020, 10, 10)

dates(doc)

print(f"{'expression':<20}  label")
print(f"{'----------':<20}  -----")

for span in doc.spans['dates']:
    print(f"{span.text:<20}  {span._.date}")
