Telephone number format not de-identified

[sandertan]

The telephone number format 06 18 34 56 78 is currently not de-identified with DEDUCE. I suspect this format is not uncommon, so it might be worth adding functionality for it to DEDUCE.

import deduce
text = u"De patient J. Jansen (e: j.jnsen@email.com, t: 06 18 34 56 78) is 64 jaar oud."
print(deduce.deidentify_annotations(deduce.annotate_text(text)))

De <PERSOON-1> (e: <URL-1>, t: 06 18 34 56 78) is <LEEFTIJD-1> jaar oud.

Interestingly, the first 4 numbers can be recognized as date:

import deduce
text = u"De patient J. Jansen (e: j.jnsen@email.com, t: 06 12 34 56 78) is 64 jaar oud."
print(deduce.deidentify_annotations(deduce.annotate_text(text)))

De <PERSOON-1> (e: <URL-1>, t: <DATUM-1> 56 78) is <LEEFTIJD-1> jaar oud.
