1 引言

LLM非常擅长将输入转换成不同的格式，例如多语种文本翻译、拼写及语法纠正、语气调整、格式转换等。

本章节将介绍如何使用编程的方式，调用API接口来实现“文本转换”功能。

首先，我们需要OpenAI包，加载API密钥，定义getCompletion函数。

In [7]:

import openai
import os
OPENAI_API_KEY = os.environ.get("OPENAI_API_KEY2")
openai.api_key = OPENAI_API_KEY

def get_completion(prompt, model="gpt-3.5-turbo", temperature=0): 
    messages = [{"role": "user", "content": prompt}]
    response = openai.ChatCompletion.create(
        model=model,
        messages=messages,
        temperature=temperature, # 值越低则输出文本随机性越低
    )
    return response.choices[0].message["content"]

2 文本翻译

中文转西班牙语

In [2]:

prompt = f"""
将以下中文翻译成西班牙语: \ 
```您好，我想订购一个搅拌机。```
"""
response = get_completion(prompt)
print(response)

Hola, me gustaría ordenar una batidora.

识别语种

In [3]:

prompt = f"""
请告诉我以下文本是什么语种: 
```Combien coûte le lampadaire?```
"""
response = get_completion(prompt)
print(response)

这是法语。

多语种翻译

In [4]:

prompt = f"""
请将以下文本分别翻译成中文、英文、法语和西班牙语: 
```I want to order a basketball.```
"""
response = get_completion(prompt)
print(response)

中文：我想订购一个篮球。
英文：I want to order a basketball.
法语：Je veux commander un ballon de basket.
西班牙语：Quiero pedir una pelota de baloncesto.

翻译+正式语气

In [6]:

prompt = f"""
请将以下文本翻译成中文，分别展示成正式与非正式两种语气: 
```Would you like to order a pillow?```
"""
response = get_completion(prompt)
print(response)

正式语气：请问您需要订购枕头吗？
非正式语气：你要不要订一个枕头？

通用翻译器

随着全球化与跨境商务的发展，交流的用户可能来自各个不同的国家，使用不同的语言，因此我们需要一个通用翻译器，识别各个消息的语种，并翻译成目标用户的母语，从而实现更方便的跨国交流。

In [2]:

user_messages = [
  "La performance du système est plus lente que d'habitude.",  # System performance is slower than normal         
  "Mi monitor tiene píxeles que no se iluminan.",              # My monitor has pixels that are not lighting
  "Il mio mouse non funziona",                                 # My mouse is not working
  "Mój klawisz Ctrl jest zepsuty",                             # My keyboard has a broken control key
  "我的屏幕在闪烁"                                             # My screen is flashing
]

In [8]:

for issue in user_messages:
    prompt = f"告诉我以下文本是什么语种，直接输出语种，如法语，无需输出标点符号: ```{issue}```"
    lang = get_completion(prompt)
    print(f"原始消息 ({lang}): {issue}\n")

    prompt = f"""
    将以下消息分别翻译成英文和中文，并写成
    中文翻译：xxx
    英文翻译：yyy
    的格式：
    ```{issue}```
    """
    response = get_completion(prompt)
    print(response, "\n=========================================")

原始消息 (法语): La performance du système est plus lente que d'habitude.

中文翻译：系统性能比平时慢。
英文翻译：The system performance is slower than usual. 
=========================================
原始消息 (西班牙语): Mi monitor tiene píxeles que no se iluminan.

中文翻译：我的显示器有一些像素点不亮。
英文翻译：My monitor has pixels that don't light up. 
=========================================
原始消息 (意大利语): Il mio mouse non funziona

中文翻译：我的鼠标不工作了。
英文翻译：My mouse is not working. 
=========================================
原始消息 (波兰语): Mój klawisz Ctrl jest zepsuty

中文翻译：我的Ctrl键坏了
英文翻译：My Ctrl key is broken. 
=========================================
原始消息 (中文): 我的屏幕在闪烁

中文翻译：我的屏幕在闪烁。
英文翻译：My screen is flickering. 
=========================================

3 语气/风格调整

写作的语气往往会根据受众对象而有所调整。例如，对于工作邮件，我们常常需要使用正式语气与书面用词，而对同龄朋友的微信聊天，可能更多地会使用轻松、口语化的语气。

In [9]:

prompt = f"""
将以下文本翻译成商务信函的格式: 
```小老弟，我小羊，上回你说咱部门要采购的显示器是多少寸来着？```
"""
response = get_completion(prompt)
print(response)

尊敬的XXX（收件人姓名）：

您好！我是XXX（发件人姓名），在此向您咨询一个问题。上次我们交流时，您提到我们部门需要采购显示器，但我忘记了您所需的尺寸是多少英寸。希望您能够回复我，以便我们能够及时采购所需的设备。

谢谢您的帮助！

此致

敬礼

XXX（发件人姓名）

4 格式转换

ChatGPT非常擅长不同格式之间的转换，例如JSON到HTML、XML、Markdown等。在下述例子中，我们有一个包含餐厅员工姓名和电子邮件的列表的JSON，我们希望将其从JSON转换为HTML。

In [9]:

data_json = { "resturant employees" :[ 
    {"name":"Shyam", "email":"shyamjaiswal@gmail.com"},
    {"name":"Bob", "email":"bob32@gmail.com"},
    {"name":"Jai", "email":"jai87@gmail.com"}
]}

In [10]:

prompt = f"""
将以下Python字典从JSON转换为HTML表格，保留表格标题和列名：{data_json}
"""
response = get_completion(prompt)
print(response)

<table>
  <caption>resturant employees</caption>
  <thead>
    <tr>
      <th>name</th>
      <th>email</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Shyam</td>
      <td>shyamjaiswal@gmail.com</td>
    </tr>
    <tr>
      <td>Bob</td>
      <td>bob32@gmail.com</td>
    </tr>
    <tr>
      <td>Jai</td>
      <td>jai87@gmail.com</td>
    </tr>
  </tbody>
</table>

In [11]:

from IPython.display import display, Markdown, Latex, HTML, JSON
display(HTML(response))

resturant employees

name	email
Shyam	shyamjaiswal@gmail.com
Bob	bob32@gmail.com
Jai	jai87@gmail.com

5 拼写及语法纠正

拼写及语法的检查与纠正是一个十分常见的需求，特别是使用非母语语言，例如发表英文论文时，这是一件十分重要的事情。

以下给了一个例子，有一个句子列表，其中有些句子存在拼写或语法问题，有些则没有，我们循环遍历每个句子，要求模型校对文本，如果正确则输出“未发现错误”，如果错误则输出纠正后的文本。

In [14]:

text = [ 
  "The girl with the black and white puppies have a ball.",  # The girl has a ball.
  "Yolanda has her notebook.", # ok
  "Its going to be a long day. Does the car need it’s oil changed?",  # Homonyms
  "Their goes my freedom. There going to bring they’re suitcases.",  # Homonyms
  "Your going to need you’re notebook.",  # Homonyms
  "That medicine effects my ability to sleep. Have you heard of the butterfly affect?", # Homonyms
  "This phrase is to cherck chatGPT for spelling abilitty"  # spelling
]

In [16]:

for i in range(len(text)):
    prompt = f"""请校对并更正以下文本，注意纠正文本保持原始语种，无需输出原始文本。
    如果您没有发现任何错误，请说“未发现错误”。
    
    例如：
    输入：I are happy.
    输出：I am happy.
    ```{text[i]}```"""
    response = get_completion(prompt)
    print(i, response)

0 The girl with the black and white puppies has a ball.
1 未发现错误。
2 It's going to be a long day. Does the car need its oil changed?
3 Their goes my freedom. They're going to bring their suitcases.
4 输出：You're going to need your notebook.
5 That medicine affects my ability to sleep. Have you heard of the butterfly effect?
6 This phrase is to check chatGPT for spelling ability.

以下是一个简单的类Grammarly纠错示例，输入原始文本，输出纠正后的文本，并基于Redlines输出纠错过程。

In [18]:

text = f"""

mine from my room.  Yes, adults also like pandas too.  She takes \

ears is a bit lower than the other, and I don't think that was \
designed to be asymmetrical. It's a bit small for what I paid for it \
though. I think there might be other options that are bigger for \
the same price.  It arrived a day earlier than expected, so I got \
to play with it myself before I gave it to my daughter.
"""

In [14]:

prompt = f"校对并更正以下商品评论：```{text}```"
response = get_completion(prompt)
print(response)
