Consultation dates

The eds.consultation-dates matcher consists of two main parts:

  • A matcher which finds mentions of consultation events (more details below)
  • A date parser (see the corresponding pipe) that links a date to those events

Examples

Note

The matcher has been built to run on consultation notes (CR-CONS at APHP), so please filter accordingly before proceeding.

import edsnlp

nlp = edsnlp.blank("eds")
nlp.add_pipe("eds.sentences")
nlp.add_pipe(
    "eds.normalizer",
    config=dict(
        lowercase=True,
        accents=True,
        quotes=True,
        pollution=False,
    ),
)
nlp.add_pipe("eds.consultation_dates")

text = """
XXX
Objet : Compte-Rendu de Consultation du 03/10/2018.
XXX
"""

doc = nlp(text)

doc.spans["consultation_dates"]
# Out: [Consultation du 03/10/2018]

doc.spans["consultation_dates"][0]._.consultation_date.to_datetime()
# Out: DateTime(2018, 10, 3, 0, 0, 0, tzinfo=Timezone('Europe/Paris'))

Extensions

The eds.consultation_dates pipeline declares one extension on the Span object: the consultation_date attribute, which is a Python datetime object.

Parameters

PARAMETER DESCRIPTION
nlp

Language pipeline object

TYPE: PipelineProtocol

consultation_mention

List of RegEx for consultation mentions.

  • If type==list: Overrides the default list
  • If type==bool: Uses the default list of True, disable if False

This list contains terms directly referring to consultations, such as "Consultation du..." or "Compte rendu du...". This list is the only one enabled by default since it is fairly precise and not error-prone.

TYPE: Union[List[str], bool] DEFAULT: True

town_mention

List of RegEx for all AP-HP hospitals' towns mentions.

  • If type==list: Overrides the default list
  • If type==bool: Uses the default list of True, disable if False

This list contains the towns of each AP-HP's hospital. Its goal is to fetch dates mentioned as "Paris, le 13 décembre 2015". It has a high recall but poor precision, since those dates can often be dates of letter redaction instead of consultation dates.

TYPE: Union[List[str], bool] DEFAULT: False

document_date_mention

List of RegEx for document date.

  • If type==list: Overrides the default list
  • If type==bool: Uses the default list of True, disable if False

This list contains expressions mentioning the date of creation/edition of a document, such as "Date du rapport: 13/12/2015" or "Signé le 13/12/2015". Like town_mention patterns, it has a high recall but is prone to errors since document date and consultation date aren't necessary similar.

TYPE: Union[List[str], bool] DEFAULT: False
