we are getting wrong output one of your example what you explained in the document named chatbot_ner/docs/api_call.md

[prasannaonchip]

message = u'I want to order 2 burgers from mainland china at 3 pm '
entity_name = 'restaurant'
structured_value=None
fallback_value=None
bot_message=None
source_language='en'

from ner_v1.chatbot.entity_detection import get_text
output = get_text(message=message, entity_name=entity_name,
structured_value=structured_value,
fallback_value=fallback_value,
bot_message=bot_message,language=source_language)
print(output)

we tested the example of this by using the python shell the actual output in my system is

[{'original_text': 'mainland china', 'detection': 'message', 'language': 'en', 'entity_value': {'crf_model_verified': False, 'value': 'Mainland China', 'datastore_verified': True}}]

but in your document the output is
output:
[
{
"detection": "message",
"original_text": "2",
"entity_value": { "value": "2", "unit": null},
"language": "en"
},
{
"detection": "message",
"original_text": "3 pm",
"entity_value": { "mm": 0, "hh": 3, "nn": "pm"},
"language": "en"
}
]

Example 2:
// If today is 19th feb
input:
message = u'I have my maths exam next Saturday.'
entity_name = 'date'
structured_value = None
structured_value_verification = 0
fallback_value = None
bot_message = None

output:[
{
"detection": "message",
"original_text": "inferno",
"entity_value": {"value": {"mm":03, "yy": 2019, "dd": 02, "type": "date"}},
"language": "en"
},
]

for example 2 we are getting the output is None
why it is not working properly
please reply fast
thank in advance.

The docs are somewhat wrong

If you run TextDetector with entity_name restaurant and number detector , you'll get the correct outputs

from ner_v2.detectors.numeral.number.number_detection import NumberDetector
message = u'I want to order 2 burgers from mainland china at 3 pm '
structured_value=None
fallback_value=None
restaurant_detector = TextDetector(entity_name='restaurant', source_language_script='en')
number_detector = NumberDetector(entity_name='number', language='en')
print(restaurant_detector.detect(message=message, structured_value=structured_value, fallback_value=fallback_value))
print(number_detector.detect(message=message, structured_value=structured_value, fallback_value=fallback_value))

[{'detection': 'message',
  'entity_value': {'value': u'Mainland China'},
  'language': 'en',
  'original_text': u'mainland china'}]

[{'detection': 'message',
  'entity_value': {'unit': None, 'value': '2'},
  'language': 'en',
  'original_text': u'2'},
 {'detection': 'message',
  'entity_value': {'unit': None, 'value': '3'},
  'language': 'en',
  'original_text': u'3'}]

How to use multiple entities in python
in your documents you people are explained the one example which multiple entities in the form of list
example is
entities = ['date','time','restaurant']
message = "Reserve me a table today at 6:30pm at Mainland China and on Monday at 7:00pm at Barbeque Nation"
which is present in the document named as chatbot_ner/docs/install.md

here for this we tried this in the form of

from ner_v1.chatbot.entity_detection import get_text
from ner_v2.detectors.temporal.date.date_detection import DateAdvancedDetector
from ner_v2.detectors.temporal.time.time_detection import TimeDetector

message = "Reserve me a table today at 6:30pm at Mainland China and on Monday at 7:00pm at Barbeque Nation"
entity_name = ['date','time','restaurant']
structured_value=None
fallback_value=None
bot_message=None
source_language='en'
timezone='UTC'
past_date_referenced=False

detector = DateAdvancedDetector(entity_name=[0],language=source_language,timezone=timezone,past_date_referenced=past_date_referenced)
output_date = detector.detect(message=message, entity_name=[0],structured_value=structured_value,fallback_value=fallback_value)

detector = TimeDetector(entity_name=entity_name[1], language=source_language,timezone=timezone)
output_time = detector.detect(message=message, entity_name=entity_name[1],structured_value=structured_value,fallback_value=fallback_value)

output_res = get_text(message=message, entity_name=entity_name[2],
structured_value=structured_value,fallback_value=fallback_value,bot_message=bot_message,language=source_language)

here we are getting the error like this
Traceback (most recent call last):
File "3.py", line 33, in
fallback_value=fallback_value)

if self.now_date.month > mm:
TypeError: '>' not supported between instances of 'int' and 'NoneType'

individually time, date, text all are working fine by combining this two(by adding date and time) or(text and date) or three(combination of text ,date ,time ) is not working properly.

please reply fast
thanks in advance

I'll address this in #275 when I get some more time to reply. Please avoid duplicating issues.
