Feature request: date cues and context

[cvinot]

Feature type

Date detection pattern enhancement and/or cues to let know which tokens indicated mentions of date properties (mode, period, bound, direction) in a given date span. Context of the relative date if known (contextual, enunciation).

Description

I'm working on various use cases on dates, which I'm struggling to make work with your package, due to it requiring additional properties or cues on date pattern detection.

I would like to know

• if you are thinking about these use cases, or if you don't plan on working on them.
• If you could add cues on what patterns allowed to identify date properties (mode, period, bound, direction) to let users figure their own rules afterwards.

I could also try to work on modifying your date model etc... I just don't know exactly what are your plans on that subject, and wouldn't want to produce work in the wrong direction.

Some of these use cases:

age/relative date disambiguation:
"Je vois ce jour le patient à deux mois du premier cycle par ..." => relative date -2 months
"On note un cancer du poumon chez sa mère à 48 ans" => age mention.
"Diagnostique à 35 ans. Stabilisation de la maladie puis récidive à 40 ans" => age mentions

disambiguation "contextual vs enunciation" context on relative dates
Some date mentions clearly identify a date of reference which can be contextual or at the date of enunciation depending on the formulation used. In your patterns they are mixed up.

Ex:
"Il y à 4 ans...", "Depuis 4 ans..." "l'an dernier" => refers to the enunciation context
"4 ans auparavant/avant/après..." => refers to the contextual date

Let me know !
