简介
溪云初起日沉阁，山雨欲来风满楼。
小伙伴们好，我是微信公众号《小窗幽记机器学习》的小编：卖老班章的小女孩。紧接前面几篇ChatGPT Prompt工程和应用系列文章：
- 04:ChatGPT Prompt编写指南
- 05:如何优化ChatGPT Prompt？
- 06:ChatGPT Prompt实践：文本摘要&推断&转换
- 07:ChatGPT Prompt实践：以智能客服邮件为例
- 08:ChatGPT Prompt实践：如何用ChatGPT构建点餐机器人？
- 09:基于ChatGPT构建智能客服系统(query分类&安全审核&防注入)
- 10:如何编写思维链Prompt？以智能客服为例
- 11:LangChain危矣？亲测ChatGPT函数调用功能：以天气问答为例
- 12:实测OpenAI函数调用功能：以数据库问答为例
今天这篇小作文是吴恩达《Building Systems with the ChatGPT API》课程的第2篇笔记。延续前文思维链Prompt的编写，今天这篇小作文依然以智能客服场景为例，介绍如何通过将复杂任务拆分为一系列简单的子任务来链接多个Prompts。如果需要IPython Notebook版代码，请在微信公众号：小窗幽记机器学习上添加小编微信。
示例1: 抽取query中相关产品和类别
前文已经展示如何对用户的查询(query)进行分类，得到类别结果比如该query是涉"账户问题"还是"产品问题"。然后根据不同类别，执行不同业务逻辑。
delimiter = "####"
system_message = f"""
你将获得客户服务咨询。客户服务咨询将使用{delimiter}字符进行分隔。\
输出一个Python对象列表，其中每个对象具有以下格式：\
'category': <计算机和笔记本、智能手机和配件、电视和家庭影院系统、游戏机和配件、音频设备、相机和摄像机之一>,
或者
'products': <必须是在下面的允许产品列表中找到的产品列表>
类别和产品必须在客户服务咨询中找到。\
如果提到了某个产品，则该产品必须与允许产品列表中的正确类别相关联。
如果未找到任何产品或类别，则输出一个空列表。
允许的产品：
计算机和笔记本类别：
TechPro超极本
BlueWave游戏笔记本电脑
PowerLite可转换本
TechPro台式机
BlueWave Chromebook
智能手机和配件类别：
SmartX ProPhone
MobiTech PowerCase
SmartX MiniPhone
MobiTech无线充电器
SmartX耳机
电视和家庭影院系统类别：
CineView 4K电视
SoundMax家庭影院
CineView 8K电视
SoundMax音响
CineView OLED电视
游戏机和配件类别：
GameSphere X
ProGamer手柄
GameSphere Y
ProGamer方向盘
GameSphere VR头盔
音频设备类别：
AudioPhonic降噪耳机
WaveSound蓝牙音箱
AudioPhonic真无线耳机
WaveSound音响
AudioPhonic唱片机
相机和摄像机类别：
FotoSnap单反相机
ActionCam 4K
FotoSnap无反相机
ZoomMaster摄像机
FotoSnap即时相机
只输出对象列表，不包含其他内容。
"""
user_message_1 = f"""
我想了解下smartx pro phone 和 \
fotosnap单反相机。 \
此外，还有关于你们的tvs"""
messages = [
{'role':'system',
'content': system_message},
{'role':'user',
'content': f"{delimiter}{user_message_1}{delimiter}"},
]
category_and_product_response_1 = get_completion_from_messages(messages)
print(category_and_product_response_1)
ChatGPT 回复如下：
[{'category': '智能手机和配件'}, {'products': ['SmartX ProPhone']}, {'category': '相机和摄像机'}, {'products': ['FotoSnap单反相机']}, {'category': '电视和家庭影院系统'}, {'products': ['CineView 4K电视', 'CineView 8K电视', 'CineView OLED电视']}]
示例2: 咨询不在清单内的产品
user_message_2 = f"""我的路由器坏了"""
messages = [
{'role':'system',
'content': system_message},
{'role':'user',
'content': f"{delimiter}{user_message_2}{delimiter}"},
]
response = get_completion_from_messages(messages)
print(response)
由于路由器不在产品清单里面，所以返回结果为空，符合预期。
[ ]
示例3: 用户表述某个产品坏了
user_message_2 = f"""我的电视坏了"""
messages = [
{'role':'system',
'content': system_message},
{'role':'user',
'content': f"{delimiter}{user_message_2}{delimiter}"},
]
response = get_completion_from_messages(messages)
print(response)
ChatGPT 回复结果如下：
[{'category': '电视和家庭影院系统'}, {'products': []}]
示例4: 返回产品详情
返回相关产品和类别的详情
进一步增加产品的详情，能够通过产品名和类型找到对应产品的详情。

总结
本文以更加复杂的智能客服场景为例，通过构建链接多个Prompt实现复杂的客服问答服务。在实际工作过程，对于复杂任务需要将其拆分为一系列简单的子任务来链接多个Prompt。这种链接多个Prompt的方式与此前介绍的思维链不同。思维链Prompt是使用一个长而复杂的指令，实质上只有一条Prompt，对任务的处理是一次完成。而链接多个Prompt是将一个任务拆解成多个模块，每个子任务单独用一个prompt完成。面对复杂的任务，通过分解成多个子任务，链接多个Prompt的方式，使其更易于管理，并减少错误的可能性。
