<condition>标签类似于编程语言中的switch语句。 它有助于ALICE响应匹配的输入。

语法

<condition name = "variable-name" value = "variable-value"/>

例如，请考虑以下对话。

Human: How are you feeling today
Robot: I am happy!

在这里，我们将happy存放为ALICE的状态，看看它是如何响应“I am happy!”。

示例

在D:/software/ab/bots/test/aiml目录中创建一个文件：condition.aiml，并在D:/software/ab/bots/test/aimlif目录中创建一个文件：condition.aiml.csv。

文件：condition.aiml

<?xml version = "1.0" encoding = "UTF-8"?>
<aiml version = "1.0.1" encoding = "UTF-8"?>
   <category>
      <pattern> HOW ARE YOU FEELING TODAY </pattern>

      <template>
         <think><set name = "state"> happy</set></think>
         <condition name = "state" value = "happy">
            I am happy!
         </condition>

         <condition name = "state" value = "sad">
            I am sad!
         </condition>
      </template>

   </category>
</aiml>

文件：condition.aiml.csv -

0,HOW ARE YOU FEELING TODAY,*,*,
   <think>
      <set name = "state"> happy</set>
   </think>

   <condition name = "state" value = "happy">I am happy!</condition>
   <condition name = "state" value = "sad">I am sad!</condition>,condition.aiml

执行程序

打开命令提示符。 进入目录：D:/software/ab 并键入以下命令 -

java -cp lib/Ab.jar Main bot = test action = chat trace = false

执行上面示例代码，得到以下结果 -

Human: How are you feeling today
Robot: I am happy!
