总结（Summarizing）能力

总结能力是我最喜欢的模型能力。很多的文章是基本上没有时间去阅读的，利用模型的总结能力，可以快速的了解文章的大概。
接下来，我们用代码的方式来试验模型总结的能力。

import openai
openai.api_key="your openai key"

def get_completion (prompt, model="gpt-3.5-turbo"): 
    messages = [{"role": "user", "content": prompt}] 
    response = openai.ChatCompletion.create( 
        model=model, 
        messages=messages, 
        temperature=0
    ) 
    return response.choices[0].message["content"]

下面是一个产品的评论。

prod_review = """
Got this panda plush toy for my daughter's birthday,
who loves it and takes it everywhere. 
It's soft and super cute, and its face has a friendly look.
It's a bit small for what I paid 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 her.
"""

我们来做个30词的总结。如下：

prompt = f"""
Your task is to generate a short summary of a product review from an ecommerce site.

Summarize the review below, delimited by triple backticks, in at most 30 words.

Review: '''{prod_review}'''

"""
response = get_completion(prompt)
print(response)

Soft and cute panda plush toy loved by a child, but considered small for the price. Arrived early.

上面关于产品评论的30 word左右的总结。

如果想把这个评论总结给到发货部分（shipping department），我们可以改一个提示（short summary of a product to the shipping department， 并且，focusing on any aspectes that mention shipping and delivery)。

prompt = f"""

"""
response = get_completion(prompt)
print(response)

The customer received the panda plush toy a day earlier than expected, allowing them to play with it before giving it as a gift.

我们看上述的总结，“发货时间早于期望时间”，十分简明的

prompt = f"""

"""
response = get_completion(prompt)
print(response)

“too small fo the price paid”.

上面是我们利用总结(summarising)的能力。

现在我们来讲讲提出/摘取（extract）的能力。
我们只是要提出或摘取客户评价中我们关心的语句，应该怎么做呢？请看下面的例子（extract the info. relevant to shipping and delivery…）。

prompt = f"""
Your task is to extract relevant information of a product review from an ecommerce site to give feedback to the Shipping department.

"""
response = get_completion(prompt)
print(response)

The product arrived a day earlier than expected.

假如我们有很多评论，希望做一个快速的总结和浏览，以了解其大概。我们可以见下面的示例。

下面是三个不同产品的评论。

review_1 = prod_review

# review for a standing lamp
review_2 = """
Needed a nice lamp for my bedroom, and this one \
had additional storage and not too high of a price \
point. Got it fast - arrived in 2 days. The string \
to the 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. Then I had a \
missing part, so I contacted their support and they \
very quickly got me the missing piece! Seems to me \
to be a great company that cares about their customers \
and products.
"""

# review for an electric toothbrush
review_3 = """
My dental hygienist recommended an electric toothbrush, \
which is why I got this. The battery life seems to be \
pretty impressive so far. After initial charging and \
leaving the charger plugged in for the first week to \
condition the battery, I've unplugged the charger and \
been using it for twice daily brushing for the last \
3 weeks all on the same charge. But the toothbrush head \
is too small. I've seen baby toothbrushes bigger than \
this one. I wish the head was bigger with different \
length bristles to get between teeth better because \
this one doesn't. Overall if you can get this one \
around the 50 mark, it's a good deal. The manufacturers’ \
replacements heads are pretty expensive, but you can \
get generic ones those are more reasonably priced. This \
toothbrush makes me feel like I've been to the dentist \
every day. My teeth feel sparkly clean!
"""

# review for a blender
review_4 = """
So, they still had the 17 piece system on seasonal \
sale for around49 in the month of November, about \
half off, but for some reason (call it price gouging) \
around the second week of December the prices all went \
up to about anywhere from between 70-89 for the same \
system. And the 11 piece system went up around 10 or \
so in price also from the earlier sale price of29. \
So it looks okay, but if you look at the base, the part \
where the blade locks into place doesn't look as good \
as in previous editions from a few years ago, but I \
plan to be very gentle with it (example, I crush \
very hard items like beans, ice, rice, etc. in the \
blender first then pulverize them in the serving size \
I want in the blender then switch to the whipping \
blade for a finer flour, and use the cross cutting blade \
first when making smoothies, then use the flat blade \
if I need them finer/less pulpy). Special tip when making \
smoothies, finely cut and freeze the fruits and \
vegetables (if using spinach-lightly stew soften the \
spinach then freeze until ready for use-and if making \
sorbet, use a small to medium sized food processor) \
that you plan to use that way you can avoid adding so \
much ice if at all-when making your smoothie. \
After about a year, the motor was making a funny noise. \
I called customer service but the warranty expired \
already, so I had to buy another one. PYI: The overall \
quality has gone done in these types of products, so \
they are kind of counting on brand recognition and \
consumer loyalty to maintain sales. Got it in about \
two days.
"""

reviews = [review_1, review_2, review_3, review_4]

我们快速生成每个评估的总结，每段总结在20字左右。

for i in range(len(reviews)):
    prompt = f"""
    Your task is to generate a short summary of a product review from an ecommerce site.

1 ```Nice lamp with storage, fast delivery, excellent customer service. Great company that cares about customers and products.``` 

2 The reviewer recommends the electric toothbrush for its impressive battery life, but criticizes the small toothbrush head. 

3 The reviewer mentions a price increase, a slight flaw in the base, and a motor issue after a year.
