Jovo platform web - input

#1

Hi everybody!

I have a problem. I am trying to create a chatbot, integrated in an ionic app, but I have a big problem:
jovo doesn’t recognize correctly my inputs in phrases, so it return me a error.

How can I resolve this problem?

Hi @Simone_Leo, welcome to the Jovo community :tada:

Could you elaborate a bit more where you’re running into problems? Could you share relevant request JSONs and error messages?

Hi @jan,
Yes, now I try to explain better.
In my app.js I have:
…
const webPlatform = new WebPlatform();

webPlatform.use(new NlpjsNlu({ 
  languages: ['it'],
 }));

app.use(
  webPlatform,
  new JovoDebugger(),
  new FileDb()
);

…
So, in this project I have a web platform, made in Ionic.

My question is: since I don’t use Alexa or Dialogflow, when creating an intent, what kind of inputs should I assign to it? How do I create an intent with variables?
{
“name”: “TestIntent”,
“phrases”: [
“I have {number} apple”
],
“inputs”: [
{
“name”: “number”,
“type”: // what’s the correct type?
}
]
}

Moreover, jovo confuses intents, if I use a word that is contained in two different sentences of two different intents, it doesn’t know which intent I’m referring to.

@jan The error that I have is this:

Seems like you don’t have StartState.GetHoursIntent in your app.js, could you take a look there?

#7

Here’s a workaround for numbers using Nlp.js: https://github.com/jovotech/jovo-starter-web-standalone/issues/5

#8

If I need other types of variables, different of number, what I need to do?

#9

Add them as input type: https://www.jovo.tech/marketplace/jovo-model#input-types

#10

Sorry @jan, I didn’t understand a thing. I do the the workaround how the example

const nlpjsNlu = new NlpjsNlu({
  setupModelCallback: async (handleRequest, nlp) => {
    // force entity extraction
    nlp.forceNER = true;
    // register module for entity extraction
    nlp.container.use(BuiltinDefault, 'extract-builtin');
    // register module for English
    nlp.use(LangEn);
    // add corpus via path to the models directory
    // you might change it to pass an absolute path
    nlpjsNlu.addCorpus('./models');
  },
});

But in the models file, how can I do the intent?

{
      "name": "GetHoursIntent",
      "phrases": [
        "I slept {hours} hours"
      ],
      "inputs": [
        {
          "name": "hours",
          "type": {
            // what is the correct type?
          }
        }
      ]
    }
#11

also, with the workaround I get this error:

unhandledRejection
  {}
  Error: ENOENT: no such file or directory, scandir './models/it-IT.json'
  {"errno":-2,"code":"ENOENT","syscall":"scandir","path":"./models/it-IT.json"}
  Error: ENOENT: no such file or directory, scandir './models/it-IT.json'
  {"errno":-2,"code":"ENOENT","syscall":"scandir","path":"./models/it-IT.json"}
#12

With this workaround it doesn’t find the intent

I think in this example, it would be

"type": { "nlpjs": "number" }

And for the next one:

It apparently triggered the None intent, which means NLPjs couldn’t find a match for your input. You can make sure the app doesn’t throw an error then by adding None (or UNHANDLED) to your handler

#14

For the workaround, did you follow all the necessary steps and adjust for your example? https://github.com/jovotech/jovo-starter-web-standalone/issues/5#issuecomment-866085494

e.g. the language package @nlpjs/lang-en needs to be replaced with @nlpjs/lang-it for you

#15

Thank you @jan
Last thing, in the workaround’s example, at last it does

nlpjsNlu.addCorpus('./models');

The ‘./models’ is the path of the models file? In my case it-IT.json?
Can you send me an example of this specific models file please?

#16

Have you tried it with a few things, like ./models/it-IT?

#17

Yes, but I have an error in console like “path not find”
@jan

#18

Is your model in ./models/it-IT relatively from the src folder? Might be possible that you need to adjust the path. I think the code example assumes that the language model is in src/models/it-IT

#19

My models file is out the src folder. So should I add it to the src folder?

#20

Yes, you could do that

Thank you @jan
