1.开发环境

开发语言:Python
技术框架:Flask、爬虫
数据库:MySQL
开发工具:PyCharm

2 系统设计

2.1 设计背景

互联网及数字技术的进步不仅改变了人们的生活方式,也深刻影响了文学创作和传播的途径。网络小说作为一种新兴的文学形式,以其独特的传播方式和广泛的受众基础,在文学领域占据了不可忽视的位置。对网络小说进行有效的信息搜集和数据分析,能够为推动网络文学健康发展、丰富文化生活提供有力的技术支撑。因此,本课题致力于通过Python编程语言,结合Scrapy爬虫技术、数据处理技术及Django框架,开发出一套完整的网络小说数据爬取、处理、存储与可视化分析系统。通过本系统的实现,既优化了网络小说的阅读推荐机制,也为文学研究提供了新的视角和方法,具有重要的理论意义和应用价值。
在数字化时代背景下,网络文学作为一种新兴的文学表现形式,利用互联网这一平台迅速发展并形成了独特的文化现象。网络小说,作为网络文学的一个重要分支,以其丰富多样的题材、便捷的阅读方式吸引了大量读者。随着网络小说数量的激增,如何从中筛选出优质作品,确保读者能够高效地获取感兴趣的内容,成为了一个亟待解决的问题。因此,设计并开发一套基于Python的网络小说榜单信息爬取与数据可视化系统,对于优化网络文学资源的利用、促进其健康发展具有重要的实践价值。
随着大数据时代的到来,小说阅读逐渐从纸质阅读时代转为了电子阅读时代,用户习惯的改变也使得网络小说的数量呈现出了指数级爆炸式的增长。早在20年代我国网络小说市场规模就已经达到了249.8亿元,用户规模达到了4.60亿人,占中国网民规模的46.5%。创作的网络小说数量也近乎有2905.9万部。这些数据的展现,也表示了近年来我国网络小说网站数量也呈倍数增长,较为知名的有起点小说网、笔趣阁小说网、飞卢中文网和书旗小说网等,行业的热度也是居高不下。除此之外,我国网文小说在海外地区包括美国,东南亚,俄罗斯等地区也颇具热度。

2.2 设计内容

通过对网络小说榜单信息爬取与数据可视化平台的具体分析和功能需要分析。将平台分为了数据采集、数据清洗和处理、数据可视化以及用户端页面设计和管理端页面设计等几个不同的功能。数据采集就是对起点中文网中小说榜单数据的采集,以及对反爬机制的处理。其中就有这使用合适的请求头、代理池等技术。数据处理分析则包含的有对重复值处理、空值处理、异常处理等方法。数据可视化则在管理端页面用户看板哪里以大屏方式体现。
其中用户端页面包含用户的登录、注册、并将抓取到的小说数据展示在网络小说页面,可对其进行搜索查询。新闻资讯页面可查看管理端发布的新闻热点。每个用户也可将感受发布到留言板。其用户功能模块结构图如图3所示。
管理端页面具备了可以对用户信息的显示并操作,对小说榜单的抓取。对用户提交的留言进行管理。还有对整个系统的管理选项,其中包含发布系统公告等一系列功能。
