Watson对话-从嵌套上下文中检索特定数据 [英] Watson Conversation - Retrieving specific data from nested context

问题描述

我希望交互看起来像这样:

I'd like the interaction to look like this:

• 批注:命名国家
• 用户:墨西哥
• Bot:墨西哥的人口为 大约120M.

• Bot: Name a country
• User: Mexico
• Bot: The population of Mexico is approximately 120M.

现在，我已经对人群进行了硬编码，如下所示:

For now, I've got the populations hard-coded and looks like below:

{
  "context": {
    "inputcountry": "<?@Country?>",
    "populations": {
      "USA": "300M",
      "Mexico": "100M",
      "Japan": "127M"
    }
  },
  "output": {
    "text": {
      "append": true,
      "values": [
        "The population of $inputcountry is approximately $populations.$inputcountry"
      ]
    }
  }
}

使用用户输入作为标识符/查找来提供特定人口编号的语法是什么?

What is the syntax to provide the specific population number using the user input as the identifier/lookup?

使用$ populations.上面显示的$ inputcountry返回

Using $populations.$inputcountry shown above returns

{"USA": "300M","Mexico": "100M","Japan": "120M"}.Mexico

推荐答案

尝试<? $populations.get($inputcountry) ?>-应该可以解决问题.

Try <? $populations.get($inputcountry) ?> - that should do the trick.
