其实大家做一个智能的聊天机器人并不容易，偶这里只是实现了一个很简易的聊天机器人。 当你和这个机器人聊天的时候，每次机器人会根据你说的话的关键词找到回答的语句。如果找不到就随机的说一句默认语言。数据存储格式是xml。 以下是xml的原文件：<?xml version=”1.0″ encoding=”UTF-8″?>
<chat>
<!–默认的聊天语句–>
<default>
<content>你在哪里？</content>
<content>你还是学生吗？</content> ……… </default>
<!–回答指定关键词的语句序列–><answer> <content key=”怪”> 不怪</content>
<content key=”慢”>是啊，慢</content>
<content key=”喂”>什么事？</content>
<content key=”88″>再见</content>
<content key=”谢”>没什么好谢的</content>
<content key=”滚”>偶不会滚，偶会走</content>……<answer>
