Match slot type values

Hello.

Is it possible to match slot type values together in the Alexa Developer Console? I have 2 custom intents and 2 custom slot types:

GetCountryByCode (Intent)
- Code (Slot)
GetCodeByCountry (Intent)
- Country (Slot)

The Code slot features European country codes (i.e. CZ). The Country slot features European countries (i.e. Czech Republic).

Is there a way of matching both slot type values together so when I utter "What code is used to represent {Country}" or "What country is identified by {Code}", Alexa finds a match and returns a response? For example:

Utterance: "What country is identified by PL?"
Response: "PL represents Poland."

Thanks in advance for your help.

Liam

Hi Liam,

I have checked your interaction model. You will still have to handle the matching within your backend. I'd suggest using a simple dictionary (key/value) as data structure.

So whenever an intent is reached, for example, you can either match "PL" with "Poland" or the other way around.

Kind regards,
Gaetano

Hi, Gaetano.

Thank you for checking my interaction model and providing some advice.

In AWS Lambda and in my skill function, I created a JSON file called 'europlate.json'. I have pasted it below for your information.

[
  {
    "Code": "GB",
    "Country": "United Kingdom"
  },
  {
    "Code": "S",
    "Country": "Sweeden"
  },
  {
    "Code": "E",
    "Country": "Spain"
  },
  {
    "Code": "SLO",
    "Country": "Slovenia"
  },
  {
    "Code": "SK",
    "Country": "Slovakia"
  },
  {
    "Code": "RO",
    "Country": "Romania"
  },
  {
    "Code": "P",
    "Country": "Portugal"
  },
  {
    "Code": "PL",
    "Country": "Poland"
  },
  {
    "Code": "NL",
    "Country": "Netherlands"
  },
  {
    "Code": "M",
    "Country": "Malta"
  },
  {
    "Code": "L",
    "Country": "Luxembourg"
  },
  {
    "Code": "LT",
    "Country": "Lithuania"
  },
  {
    "Code": "LV",
    "Country": "Latvia"
  },
  {
    "Code": "I",
    "Country": "Italy"
  },
  {
    "Code": "IRL",
    "Country": "Ireland"
  },
  {
    "Code": "H",
    "Country": "Hungary"
  },
  {
    "Code": "GR",
    "Country": "Greece"
  },
  {
    "Code": "GBZ",
    "Country": "Gibraltar"
  },
  {
    "Code": "D",
    "Country": "Germany"
  },
  {
    "Code": "F",
    "Country": "France"
  }
]

So within my index.js file, I am trying to retrieve the JSON data. So I am doing this using the following code:

const json = require('./europlate.json');
const obj = JSON.parse(json);

Is it at this point I should be using a simple dictionary (key/value) as data structure?

Thanks.

Liam
