如何在Watson Conversation中保存数据？

Question

I need save a data in Watson Conversation, for example:

-Watson say: Hello, tell me your name

-I say: My name is Isaac

-Watson say: Ok Isaac, good night!**

How can I save this value? Without telling Watson to say that when he recognizes Isaac's name. Just keep that data that is "name" and show it. And to be able to use that variable that I keep the name of Isaac in other nodes

Thank you very much!

Answer 1

In this case you can use context variables or @sys-person (check Supported languages ) within Watson Conversation to do that.

Context variables with regex:

And for get the name value, you need to use Regex to extract from the user input. And set it in all nodes that you want show the name of the user, for example.

{
  "context": {
    "name": "<? input.text.extract('yourRegextoExtractName')?>"
  },
  "output": {
    "text": {
      "values": [
        "Hi $name, how do you do?"
      ],
      "selection_policy": "sequential"
    }
  }
}

Note that I use the syntax to set the context variable: $name . So, just put in all nodes that you want show name the same syntax to set the name context variable.

@sys-person - System entities.

You can also active the @sys-person System entity, and use my example to save date below. Note that is BETA for now.

For use @sys-person, active on: Entities -> System entities -> @sys-person, see my image anothers actives system-entity:

And your Conversation condition will be something like:

Result:

• @sys-person Supported languages ;
• Try to verify how context variables works in this link , and also how to use regex inside WCS here .
• Try to see more about Expression language methods with Watson Conversation.
