三、推断（Inferring）

1. 推断情绪（正面 / 负面）

lamp_review = """
Needed a nice lamp for my bedroom, and this one had \
additional storage and not too high of a price point. \
Got it fast.  The string to our lamp broke during the \
transit and the company happily sent over a new one. \
Came within a few days as well. It was easy to put \
together.  I had a missing part, so I contacted their \
support and they very quickly got me the missing piece! \
Lumina seems to me to be a great company that cares \
about their customers and products!!
"""

prompt = f"""
What is the sentiment of the following product review, 
which is delimited with triple backticks?

Review text: '''{lamp_review}'''
"""
response = get_completion(prompt)
print(response)

代码中：
lamp_review 中文意思是：我的卧室需要一盏漂亮的台灯，而这盏灯有额外的存储空间，而且价格也不是太高。搞得很快。我们台灯的线在运输途中断了，公司很高兴地送来了一条新的。也是在几天内到来的。它很容易组合在一起。我有一个缺失的部分，所以我联系了他们的支持，他们很快就给我找到了缺失的部分！在我看来，Lumina是一家关心客户和产品的伟大公司！

In a recent survey conducted by the government,

incredible opportunities. I'm proud to be a part of 
such an innovative organization."

hear that our employees are satisfied with their work at NASA. 
We have a talented and dedicated team who work tirelessly

Social Security Administration had the lowest satisfaction

address the concerns raised by employees in the survey and 
work towards improving job satisfaction across all departments.
