一. 什么是归纳总结式的prompt开发
有时候需要对一段文本进行归纳总结,那么可以采取以下的方案:
-按照给定单词、句子或者字符的数量限制来让模型裁剪文本,使内容更精炼
-基于聚焦的主题进行总结
-只根据需求抽取相关的文本信息,不需要整段文本内容
除了上面列出的几种方式之外,还可能有额外的一些需求,譬如给出多段文本,要求模型同时对这些文本进行归纳总结。
接下来会给出具体示例,通过调用模型"gpt-3.5-turbo"来演示并解析如何针对以上谈到的这些文本归纳总结的需求,编写相应的prompts。
二. 结合案例演示解析如何使用prompt进行文本归纳总结
首先给出一段需要进行归纳总结的文本:
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.
"""
首先按照给定词汇数量限制的方式进行总结。
prompt示例如下:
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)
打印输出结果如下:
This panda plush toy is loved by the reviewer's daughter, but they feel it is a bit small for the price.
接下来修改prompt,针对产品物流这个主题进行总结。
prompt示例如下:
prompt = f"""
Your task is to generate a short summary of a product \
review from an ecommerce site to give feedback to the \
Shipping deparmtment.
Summarize the review below, delimited by triple
backticks, in at most 30 words, and focusing on any aspects \
that mention shipping and delivery of the product.
Review: ```{prod_review}```
"""
response = get_completion(prompt)
print(response)
打印输出结果如下:
The customer is happy with the product but suggests offering larger options for the same price. They were pleased with the early delivery.
继续修改prompt,从产品价格和价值方面进行总结。
prompt示例如下:
prompt = f"""
Your task is to generate a short summary of a product \
review from an ecommerce site to give feedback to the \
pricing deparmtment, responsible for determining the \
price of the product.
Summarize the review below, delimited by triple
backticks, in at most 30 words, and focusing on any aspects \
that are relevant to the price and perceived value.
Review: ```{prod_review}```
"""
response = get_completion(prompt)
print(response)
打印输出结果如下:
The reviewer is satisfied with the quality and appearance of the panda plush toy but feels that it is overpriced compared to similar options available.
下面通过修改prompt达到只抽取相关的文本信息的目的,而不需要对整段文本进行概括总结。
prompt示例如下:
prompt = f"""
Your task is to extract relevant information from \
a product review from an ecommerce site to give \
feedback to the Shipping department.
From the review below, delimited by triple quotes \
extract the information relevant to shipping and \
delivery. Limit to 30 words.
Review: ```{prod_review}```
"""
response = get_completion(prompt)
print(response)
打印输出结果如下:
The shipping department should take note that the product arrived a day earlier than expected.
接下来额外给出另外3段文本,要求模型对这4段文本同时进行总结,条件就是输出内容不能超过指定的字数限制。
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 manufactuer's \
replacements heads are pretty expensive, but you can \
get generic ones that're 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 around $49 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 of $29. \
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. FYI: 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]
prompt示例如下:
for i in range(len(reviews)):
prompt = f"""

review from an ecommerce site.
Summarize the review below, delimited by triple \
backticks in at most 20 words.
Review: ```{reviews[i]}```
"""
response = get_completion(prompt)
print(i, response, "\n")
打印输出结果如下:
0 Panda plush toy is loved by daughter, soft and cute, but small for the price. Arrived early.
1 Great lamp with storage, fast delivery, excellent customer service, and easy assembly. Highly recommended.
2 The reviewer recommends the electric toothbrush for its impressive battery life, but criticizes the small brush head.
3 The reviewer found the price increase after the sale disappointing and noticed a decrease in quality.
