Problem
In the online marketplace it created, Amazon provides customers with an opportunity to rate and review purchases. Individual ratings - called "star ratings" - allow purchasers to express their level of satisfaction with a product using a scale of 1 (low rated, low satisfaction) to 5 (highly rated, high satisfaction). Additionally, customers can submit text-based messages - called "reviews" - that express further opinions and information about the product. Other customers can submit ratings on these reviews as being helpful or not - called a "helpfulness rating" - towards assisting their own product purchasing decision. Companies use these data to gain insights into the markets in which they participate, the timing of that participation, and the potential success of product design feature choices.
Sunshine Company is planning to introduce and sell three new products in the online marketplace: a microwave oven, a baby pacifier, and a hair dryer. They have hired your team as consultants to identify key patterns, relationships, measures, and parameters in past customer-supplied ratings and reviews associated with other competing products to 1) inform their online sales strategy and 2) identify potentially important design features that would enhance product desirability. Sunshine Company has used data to inform sales strategies in the past, but they have not previously used this particular combination and type of data. Of particular interest to Sunshine Companyare time-based patterns in these data, and whether they interact in ways that will help the company craft successful products.
To assist you, Sunshine's data center has provided you with three data files for this project: hair_dryer.tsv, microwave.tsv, and pacifier.tsv. These data represent customer-supplied ratings and reviews for microwave ovens, baby pacifiers, and hair dryers sold in the Amazon marketplace over the time period(s) indicated in the data. A glossary of data label definitions is provided as well. THE DATA FILES PROVIDED CONTAIN THE ONLY DATA YOU SHOULD USE FOR THIS PROBLEM.
Requirements
Analyze the three product data sets provided to identify, describe, and support with mathematical evidence, meaningful quantitative and/or qualitative patterns, relationships, measures, and parameters within and between star ratings, reviews, and helpfulness ratings that will help Sunshine Company succeed in their three new online marketplace product offerings.
Use your analysis to address the following specific questions and requests from the Sunshine Company Marketing Director:
Identify data measures based on ratings and reviews that are most informative for Sunshine Company to track, once their three products are placed on sale in the online marketplace.
Identify and discuss time-based measures and patterns within each data set that might suggest that a product's reputation is increasing or decreasing in the online marketplace.
Determine combinations of text-based measure(s) and ratings-based measures that best indicate a potentially successful or failing product.
Do specific star ratings incite more reviews? For example, are customers more likely to write some type of review after seeing a series of low star ratings?
Are specific quality descriptors of text-based reviews such as 'enthusiastic', 'disappointed', and others, strongly associated with rating levels?
3. Write a one- to two-page letter to the Marketing Director of Sunshine Company summarizing your team's analysis and results. Include specific justification(s) for the result that your team most confidently recommends to the Marketing Director.
Your submission should consist of:
One-page Summary Sheet
Table of Contents
One- to Two-page Letter
Your solution of no more than 20 pages, for a maximum of 24 pages with your summary sheet, table of contents, and two-page letter.
Note: Reference List and any appendices do not count toward the page limit and should appear after your completed solution. You should not make use of unauthorized images and materials whose use is restricted by copyright laws. Ensure you cite the sources for your ideas and the materials used in your report.

问题背景(Problem)
在亚马逊所创建的在线市场中,亚马逊为顾客提供了对已购商品进行评价和评论的机会。单个评价(即“星级评分”)使用一个从1到5的分值(1分表示评级低、满意度低,5分表示评级高、满意度高),让购买者表达对产品的满意程度。此外,顾客还可以提交文字评论(即“评论”),对产品发表进一步的看法与信息。其他顾客也可以对这些评论进行“帮助度评价”(helpfulness rating),表示该评论在他们购买决策中是否具有参考价值。公司利用这些数据来洞察其所参与的市场、参与的时机,以及产品设计特性对产品潜在成功的影响。
Sunshine Company计划在该在线市场上推出并销售三款新产品:微波炉、婴儿安抚奶嘴以及吹风机。他们聘请了你的团队担任顾问,目的是基于过往顾客提交的评价和评论数据(这些数据来自与他们将要竞争的产品),识别关键的模式、关系、指标以及参数,以便:
1)为它们的在线销售策略提供信息支撑;
2)确定可能提升产品吸引力的重要设计特性。
Sunshine Company此前曾利用数据来指导销售策略,但从未使用过这种特定组合和类型的数据。对Sunshine Company而言,最感兴趣的是这些数据在时间上的模式,以及这些模式是否会相互作用,从而帮助公司打造成功的产品。
为了帮助你完成分析,Sunshine的数据中心向你提供了三个数据文件:hair_dryer.tsv、microwave.tsv和pacifier.tsv。这些数据表示在给定时间段内,亚马逊市场上出售的吹风机、微波炉和婴儿安抚奶嘴的顾客评价与评论。还随附了数据标签定义的术语表。你只能使用所提供的这三个数据文件来完成此问题。
分析所提供的这三个产品数据集,从星级评分、评论以及帮助度评分中,识别、描述并以数学证据支持在这些维度之间以及它们之间相互联系的有意义的定量或定性模式、关系、指标与参数,以帮助Sunshine Company在其三款新产品的在线销售中取得成功。
基于你的分析,回答并讨论以下来自Sunshine Company营销总监的具体问题和需求:
撰写一封1到2页的给Sunshine Company营销总监的信,总结你团队的分析与结果。并在信中提供你们最有信心推荐给营销总监的结果及其理由。
你的提交内容应包括:
注意:参考文献列表以及附录不计入页面限制,应在完整解决方案之后呈现。请勿使用受版权法限制、无权使用的图片或材料。确保在报告中对所用理念和材料的来源进行适当引用。

每一行的数据都被划分为以下列(列名):
完成以上翻译后,你即可根据这些中文描述和要求来进一步进行数模与分析练习。祝你一切顺利!
现在我在考虑这一问,请问这一问我们具体到底要做什么?他的描述还挺笼统的。
分析所提供的三个产品数据集,识别、描述并以数学证据支持星级评分、评论和评论有用度评分之
间(以及它们相互之间)有意义的定量或定性模式、关系、度量和参数,这些发现将帮助阳光公司
在他们的三款新在线产品上取得成功。
在这一问里,核心任务可以概括为:
“利用所给的三个产品数据集(吹风机、微波炉、婴儿安抚奶嘴),从星级评分(star_rating)、文本评论(review)以及评论有用度(helpfulness rating)等信息中,识别并描述**(并用一定的数学或统计方法来论证)能够帮助企业在新产品上线时取得成功的各种模式、关系、度量及参数。”**
换句话说,题目给了一批相对“海量且多维度”的原始评价数据,要求你从这些数据里“提炼出对Sunshine Company有价值的分析发现”。因为题目中只说“识别关系或模式”,确实听起来有点“泛”或“笼统”,但实际上可以细分成下列几个方面去思考、去挖掘:
星级评分与时间(Time-based Analysis)
星级评分与帮助度评分/投票(Quantitative Correlations)
星级评分与文本特征(Qualitative or NLP-based Analysis)
帮助度评分(helpful_votes/total_votes)与文本或时间维度
复合关系和整体模式(Pattern/Trend Synthesis)
潜在的互动或因果
题目最终希望你从这样一系列分析中,提炼出有助于产品营销和设计的结论。比如:
所以,这个部分“看起来笼统”,其实是因为它给你留下了很大的自由度去做多维度探索分析。你可以把它理解为一个**“探索性数据分析+基础建模”的综合任务**。关键是:
只要围绕以上思路,你就能完成题目所说的:“识别、描述,并用数学证据支持:星级评分、评论文本、帮助度评分之间及它们相互之间的有意义的模式与关系”。这样做出来的结果就既具体又能够回答企业“该怎么做才能更成功”的问题。
应该怎么处理评论文本呢?如何从自然语言中获取可定量分析的信息?
在面对用户评论文本(通常是自由书写的自然语言)时,常见的目标往往是想从中提取出可度量的、可用于统计或建模的特征,并与星级评分、helpfulness 等变量进行结合分析。下面介绍几种常见的处理思路,供你在数模过程中参考:
1.1 去除噪声
.,!?;:
以及 HTML 标签、数字等(视具体需求保留或去除)。1.2 分词或令牌化(Tokenization)
目的:让文本变为更便于后续计算处理的“词”或“token”序列。
这样可以把评论文本“量化”为情感分数,再与星级评分、helpfulness 做统计回归或相关分析。例如:
- 情感分值是否与星级评分高度一致?
- 哪些评论尽管星级不低,但文本中的负面词不少,是否预示潜在不满?
关键词与评分的关系
disappointed
;若出现,平均星级评分是多少?helpfulness 投票率是多少?评论情感与星级评分的一致性
评论长度与 helpfulness
时间维度上的情感变化
从自然语言中获取定量特征,最重要的是要先定义你想要研究的问题:想看“负面评价激增”吗?想看“哪些特点与高评分强相关”吗?然后针对这些目标去选取合适的文本处理与分析方法。
在数模题目中,最常见且易上手的路径是:关键词/文本长度/情感分析。它们能比较直观地转换出数值,并快速与评分、帮助度、时间等进行可视化和定量分析。这些发现将帮助你更好地回答题目中关于“文本与评分、帮助度之间有什么关系”的问题,也能为 Sunshine 公司在新品上市时监测评论、提升产品设计和形象提供重要的参考依据。
对于这道题目的要求,请你为我给出思路分析。
下面给出一个系统化的思路框架,帮助你针对题目“分析三个产品数据集,识别并用数学证据支持星级评分、评论、帮助度评分之间(以及相互之间)有意义的模式、关系、指标、参数,从而帮助企业在新产品上线中取得成功”的要求进行思路分析。可根据实际情况调整深度或顺序。

、review_date
等字段缺失或无效,需要做适当剔除或填补。初步描述性统计

关键量化指标
对 Sunshine Company 的策略建议
用数学证据支撑
“识别、描述并以数学证据支持”:
“帮助企业在三款新产品的在线销售中取得成功”:
“定量与定性相结合”:
总体而言,这道题目看似“宽泛”,实际上正是鼓励你从多维度去挖掘数据价值。核心思路就是:
这个逻辑能够满足题目“识别、描述,并提供数学/统计支持”的要求,并为后续写报告和给营销总监的信提供充足的分析和依据。
在你的分析中,题目给出的这五个要求分别应该如何思考?
找出基于评分和评论的、最能为Sunshine Company提供信息的可追踪数据指标,一旦公司三款产品在在线市场开始销售就应重点跟踪这些指标。
阐明并讨论各数据集中基于时间的衡量标准和模式,这些模式可能暗示产品在在线市场上的声誉是上升还是下降。
确定能够最好地表明产品潜在成功或失败的文本(评论)与评分相结合的指标。
特定的星级评分是否会激发更多评论?例如,顾客在看到一系列较低的星级评分后,是否更有可能写评论?
某些文本描述(如“enthusiastic”(热情)、“disappointed”(失望)等)是否与特定的评级水平密切相关?
下面逐条为你分析题目给出的五个具体要求,并给出在分析过程中可以采用的思考与方法,帮助你更好地组织研究思路并回答这些问题。
这些组合指标能更精准地反映产品是否真正得到用户认可,也能提示企业重点关注哪些评论、哪些痛点以及时改进。
你可以把这五个要求看作五个相互关联的切入点,它们共同构成了一个完整的探索性数据分析和指标构建框架:
这些思路与方法能帮助你一一对应回答题目,并最终形成对 Sunshine Company 有实际指导意义的洞察和策略建议。
