背景随着互联网和大数据技术的发展人们可以方便地获取海量的电影信息但是如何从这些信息中找到适合自己的电影仍然是一个挑战。传统的电影推荐系统往往只能根据用户的历史行为和偏好进行推荐缺乏对电影内容的深度分析和挖掘。
目的本课题旨在利用爬虫技术从互联网上获取电影信息并通过可视化技术对这些信息进行分析和呈现从而构建一个更加智能、直观的电影推荐系统。
意义通过该研究可以为用户提供更加个性化、精准的电影推荐服务帮助用户更好地选择自己喜欢的电影同时也可以为电影产业提供更加精准的市场分析和预测。
研究思路首先利用爬虫技术从电影网站、社交媒体等平台上获取电影信息包括电影名称、导演、演员、剧情简介、评分等然后利用可视化技术对这些信息进行分析和呈现包括词云、关联图、热力图等最后根据用户的历史行为和偏好结合可视化分析结果构建智能的电影推荐系统。
研究方法主要包括爬虫技术、数据清洗和处理、可视化技术、推荐算法等。通过爬虫技术获取电影信息并进行数据清洗和处理然后利用可视化技术对数据进行分析和呈现最后结合推荐算法构建电影推荐系统。同时还可以采用用户调研和实验评估等方法对推荐系统进行优化和验证。

技术栈
PythonPython是一种高级编程语言在项目开发中Python用作后端开发语言。DjangoDjango是一个开源的Python Web框架提供了许多内置的功能如用户认证、会话、模板引擎、表单处理等使得项目能够快速地开发出功能完备的网站。Pymysqlpymysql是一个Python的MySQL数据库连接器它提供了Python与MySQL数据库之间的连接、查询、插入、更新和删除等数据库操作。Vue.jsVue.js是一个用于构建用户界面的JavaScript框架。Vue的核心库只关注视图层不仅易于学习而且容易与其他库或现有项目集成。Element UIElement UI是Vue.js的一个组件库它提供了一系列的Web组件包括表格、表单、弹窗、导航栏等。能够帮助开发者快速构建出风格一致的页面。CSS3CSS3是层叠样式表CSS的第三个版本它在项目开发中用于控制HTML元素的呈现方式。CSS3加入了很多新特性如动画、过渡、阴影等使得网页的视觉效果更加丰富和细腻。MySQL 5.7MySQL是一个开源的关系型数据库管理系统。版本5.7是MySQL的一个主要版本它引入了诸如JSON数据类型、改进的查询优化器、多源复制等新特性。MySQL用于项目存储、检索和管理数据。
