<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>
      <template>Yes <set name = "topic">movies</set></template>  
   </category>
   <topic name = "movies">

         <pattern> * </pattern>
         <template>Watching good movie refreshes our minds.</template>
