一、前言
系统介绍
本系统名为《基于大数据的Kaggle竞赛团队协作模式与效能可视化分析》，面向计算机专业毕业设计场景，围绕Kaggle竞赛数据展开大数据分析与可视化呈现。系统以Hadoop HDFS作为底层数据存储，借助Spark与Spark SQL完成竞赛数据、团队协作数据与效能指标的清洗、聚合与统计计算，并结合Pandas、NumPy对分析结果做进一步整理与指标加工，最终通过Vue、ElementUI与Echarts将分析结果以图表形式呈现。系统共包含竞赛概况分析、团队协作分析、竞赛效能分析、竞赛数据管理、决策中心决策看板、排行榜数据管理、队员数据管理、个人信息账户中心、修改密码账户中心九个功能模块，覆盖从数据接入、大数据计算、指标分析到可视化展示与账户管理的完整链路，能够对Kaggle竞赛中的团队构成、协作行为与效能表现进行较为系统的量化分析，为竞赛团队协作模式的观察与效能评估提供数据支撑。
选题背景
Kaggle作为国际上比较有代表性的数据竞赛平台，积累了大量竞赛、队伍、队员与排行榜相关的数据。这些数据本身记录了一支队伍从组队、提交到最终排名的过程，也隐含着团队规模、协作方式与最终成绩之间的关系。以往对竞赛结果的分析多停留在排行榜名次本身，队伍内部的协作行为、队员参与情况与效能表现往往被忽略，数据分散在不同页面和文件中，缺少统一的整理与计算。与此同时，大数据处理技术在教学与毕业设计中被越来越多地接触，Hadoop与Spark提供了对较大规模数据做存储与计算的能力，Spark SQL也能较为方便地完成分组统计与聚合分析。把这些技术用到Kaggle竞赛数据的整理与分析上，既能处理竞赛数据量较大的问题，也能把团队协作与效能这类偏过程性的内容量化出来。正是在这样的背景下，本课题尝试以Kaggle竞赛数据为对象，借助大数据技术完成团队协作模式与效能的分析与可视化呈现。
选题意义
从实际角度看，本课题把Kaggle竞赛中分散的竞赛信息、队伍信息和队员信息集中起来，用Spark做统计计算，再把团队协作情况和效能表现用图表展示出来，使用者可以比较直观地看到不同队伍在协作方式和成绩上的差异，对理解竞赛团队的组织方式有一定参考价值。从学习角度看，课题把Hadoop、Spark、Spark SQL、Pandas与NumPy这些大数据环节串成一条完整链路，从数据存储、计算分析到前端可视化都有涉及，对计算机专业学生熟悉大数据项目的整体流程有帮助。从能力训练角度看，课题需要处理数据清洗、指标设计和可视化呈现等具体问题，能够锻炼把实际问题拆解为可计算任务的能力。需要说明的是，本系统只是一个毕业设计层面的尝试，分析维度和数据范围都有限，所得结论更多是描述性的，距离真正成熟的竞赛分析平台还有不小差距，更多是作为一次大数据分析流程的练习和探索。
