AIML <topic>标签

<topic>标签在AIML中用于存储上下文，以便以后的对话可以基于该上下文完成。 通常，<topic>标签用于是/否类型对话。 它有助于AIML搜索在主题上下文中编写的类别。

语法

使用<set>标记定义主题 -

<template> 
   <set name = topic> topic-name </set>
</template>

使用<topic>标记定义类别 -

<topic name = topic-name>
   <category>
      ...
   </category>     
</topic>

例如，请考虑以下对话。

Human: let discuss movies
Robot: Yes movies
Human: Comedy movies are nice to watch
Robot: Watching good movie refreshes our minds.
Human: I like watching comedy
Robot: I too like watching comedy.

这里的机器人以“movies”为主题。

示例

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

文件：topic.aiml

<?xml version = 1.0 encoding = UTF-8?>
<aiml version = 1.0.1 encoding = UTF-8?>
   <category>
      <pattern>LET DISCUSS MOVIES</pattern>
