How Location identification?

Rasa Open Source
1

Hi, I am new to rasa. I am trying to implementing weather bot using openweather api. Can anyone help me out to identify location name and if user enter incorrect location name & the bot need to reply “Please mention a valid location name”

I have seen in some forum that using spacy entity extractor, but getting confused how implement.

stories.yml (548 Bytes) nlu.yml (1.8 KB) rules.yml (561 Bytes) domain.yml (1.1 KB) credentials.yml (980 Bytes) actions.py (3.2 KB) weather.py (652 Bytes)

actions.py

class ActionWeather(Action):

def name(self) -> Text:
    return "action_weather"

def run(self, dispatcher: CollectingDispatcher,
tracker: Tracker,
domain: Dict[Text, Any]) -> List[Dict[Text, Any]]:
    
    loc=tracker.get_slot('location')
    temp = int(Weather(loc)['temp']-273)
    hum =  int(Weather(loc)['humidity'])
    cond = Weather_Condition()[0]['description']
    if loc is not None:
        dispatcher.utter_message(template="utter_temp", LOC=loc, temp=temp, hum=hum, condition=cond)
    else:
        dispatcher.utter_message(template="utter_invalid")
       
    return [SlotSet('location',loc)]

Thanks

@manoj_kumarM meanwhile try change this in rules

- slot_was_set:
    - requested_slot: null

- slot_was_set:
    - requested_slot: location

@manoj_kumarM is this code is working? are you getting any result or output whilst entering any city name? I guess no?or yes?

@manoj_kumarM the weather API issue is this when you mention the location or city in the intent it will show you the result as you mentioned Goa it was in the intent example, and when you mention Berlin it will not show, but as you mention Berline in intent example it will show you result.

Please try this first, and let me know is this what I said happening or not?

15

If give London it is not giving any output?

16

@manoj_kumarM London is in intent example? check your intent weather. Did you read my above post?

17

there is no london in intent. if mention any name in weather intent then it is giving an output.

if I execute weather.py giving location name as london it is getting an output.

Is there any wrong with my slots or form and actions.py

18

@manoj_kumarM because you passing manually that’s why Weather("london")

@manoj_kumarM you need to provide all city or location name or try the concept of lookup table.

19

@nik202
Is another way to get the entity and pass it to api apart from lookup table

20

@manoj_kumarM I only know these 2, but where you required this project? or its just for getting understanding?

@manoj_kumarM If you understand the concept with the help of suggestions, I’d request to close this thread for others. Thanks.
