2020 MCM Weekend 2 Problem C: A Wealth of Data
2020年MCM周末2问题C:数据的财富

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.
在其创建的在线市场中,亚马逊为客户提供了对购买进行评分和评价的机会。个人评级-称为“星级”-使购买者可以使用1(低评级,低满意度)到5(高评级,高满意度)的等级来表示他们对产品的满意度。此外,客户可以提交基于文本的消息(称为“评论”),以表达有关产品的更多意见和信息。其他客户可以在这些评论中提交有帮助或无帮助的评分(称为“帮助评分”),以协助他们自己的产品购买决策。公司使用这些数据来深入了解其参与的市场,参与的时间以及产品设计功能选择的潜在成功。

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 customersupplied 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 Company are time-based patterns in these data, and whether they interact in ways that will help the company craft successful products.
阳光公司计划在在线市场上推出和销售三种新产品:微波炉,婴儿奶嘴和吹风机.他们已聘请您的团队作为顾问,以识别过去客户提供的与其他竞争产品相关的评分和评论的关键模式,关系,度量和参数,以:1)告知其在线销售策略; 2)确定潜在的重要设计特征,以提高产品的吸引力。Sunshine Company过去曾使用数据为销售策略提供信息,但他们以前从未使用过这种特殊的组合和数据类型。Sunshine Company特别感兴趣的是这些数据中的基于时间的模式,以及它们是否以有助于该公司制造成功产品的方式进行交互。
