Issue with accessing of date detector

[ellurunaresh]

Hi all,

I went through all the steps to install char NER. I couldn't access the DateAdvanceDetector from django shell and DateDetector doesn't have detect method.
Could you please help me out to use date detector in django

from ner_v2.detectors.temporal.date.date_detection import DateAdvanceDetector

1. detector = DateAdvanceDetector(entity_name=entity_name, language=source_language,
   timezone=timezone,
   past_date_referenced=past_date_referenced)

from ner_v2.detectors.temporal.date.date_detection import DateDetector
2.) detector = DateDetector(entity_name=entity_name, language=source_language,
timezone=timezone,
past_date_referenced=past_date_referenced)
output = detector.detect(message=message, entity_name=entity_name,
structured_value=structured_value,
fallback_value=fallback_value)

Hello, can you please post your traceback error ? I think the error is mostly because of a typo. It is DateAdvancedDetector not DateAdvanceDetector

You can use DateAdvancedDetector via code as follows.

from ner_v2.detectors.temporal.date.date_detection import DateAdvancedDetector
date_detector = DateAdvancedDetector(entity_name='date', language='en', timezone='Asia/Kolkata')
date_detector.detect('5th March')

which gives

[{'detection': 'message',
  'entity_value': {'end_range': False,
   'from': False,
   'normal': True,
   'start_range': False,
   'to': False,
   'value': {'dd': 5, 'mm': 3, 'type': 'date', 'yy': 2020}},
  'language': 'en',
  'original_text': '5th march'}]

We would not recommend to use DateDetector directly but if you want you can call .detect_entity() on DateDetector instance. Currently we are changing the API to remove the DateAdvanceDetector and directly use DateDetector.

It worked. Thanks :)
I was getting null for this sentence in date detector. Is it past/future references couldn't parse?

date_detector.detect("I am traveling next week")
