1 内容摘要（Content summary）
今天小编将从「思维导图、精读内容、知识补充」三个板块，解读分享【一种新颖的移动支付排序多属性决策方法】一文的案例研究部分。
Today, the editor will interpret and share the case study of the article "A novel multi-attribute decision-making for ranking mobile payment" from the three ps of "mind map, intensive reading content, and knowledge supplement".
2 思维导图（Mind mapping）
3 精读内容（Intensive reading content）
案例研究部分的第一段对研究背景进行了简单的介绍。颠覆性的技术改进使得移动设备获得了许多新的功能，特别是移动支付服务，正在以指数级的增速快速增长。
The first paragraph of the case study p provides a brief introduction to the research background. Disruptive technological improvements have enabled mobile devices to acquire many new functions, especially mobile payment services, which are growing at an exponential rate.
疫情的到来改变了加纳消费者对移动支付的使用行为，服务商为了获取消费者的反馈，开发了评论平台供消费者进行评论。但潜在消费者很难在做出决定前浏览所有评论，故本文提出了评估模型，帮助消费者更好地了解影响支付服务的属性，做出更好的决策。
The arrival of the epidemic has changed Ghanaian consumers' behavior towards mobile payment. In order to obtain consumer feedback, service providers have developed a review platform for consumers to comment. However, it is difficult for potential consumers to browse all reviews before making a decision, so this article proposes an evaluation model to help consumers better understand the attributes that affect payment services and make better decisions.
针对上述移动支付服务选择问题，文章确定了加纳市场上三种流行的移动支付服务。
In response to the above mobile payment service selection issues, the article identifies three popular mobile payment services in the Ghanaian market.
作者首先使用Python爬虫从谷歌商店提取了这些移动支付服务的相应评论，并将其进行预处理，提取了评论中讨论的移动支付使用属性，共有8种，包括接口复杂度、系统更新、账户注册等。
The author first used a Python crawler to extract the corresponding reviews of these mobile payment services from the Google Store and preprocessed them to extract the mobile payment usage attributes discussed in the reviews. There are 8 types in total, including interface complexity, system updates, account registration, etc.
作者通过情感分析得到了评论在每个属性下的情感得分，并将其转换为PLE，构建出了三种支付服务的综合概率语言决策矩阵。
The author obtained the sentiment score of the review under each attribute through sentiment analysis, converted it into PLE, and constructed a comprehensive probabilistic language decision matrix for the three payment services.
决策矩阵中的数值可用Matlab呈现出来，具体如下所示，s1到s3表示三种不同的支付服务，8列分别表示8种移动支付服务属性，每一列的数值相加总和为1。
The values in the decision matrix can be presented with Matlab, as shown below. s1 to s3 represent three different payment services. The 8 columns represent 8 mobile payment service attributes respectively. The sum of the values in each column is 1.
