# Visualization

## 简介

爬取B站up视频详细信息,并进行可视化

由于本项目的爬虫是单线程,所以选择的up主数据量**建议小于3000**,如果你能优化到多线程加速,欢迎pull request

### 技术栈

前端:HTML, CSS, JavaScript

后端:flask

爬虫:python

数据库:MySQL

深度学习:BiRNN->LSTM训练模型,情感分类仓库:https://github.com/Nomination-NRB/SentimentClassify

### 基本功能

- 视频数据分析
- 数据来源:up主个人主页统计
- 关注数,粉丝数,获赞数,播放数,阅读数,视频数

- 个人视频排行
- 综合评分前9个视频(降序)
- 评分算法:0.1\*view+barrage+reply+2\*favorite+2\*coin+1.5\*share+0.5*like

- 稿件时长分区
- 粉丝
- 信息:名字,关注时间,性别

- 评论情绪
- 数据来源:所有投稿视频
- 积极/消极

- 总览信息
- 所有视频的点赞,投币,收藏,评论,播放

- 稿件详情
- 评分前6的稿件的详细数据
- 可以点击分区进行单独查看数据权重

## 使用方法

```bash
git clone https://github.com/Nomination-NRB/VisualBilibili
```

在vscode或者其他编译器打开项目文件夹

激活本项目具体使用的环境,切换到requirements.txt目录下在终端执行该命令即可

```python
pip install -r requirements.txt
```

1. **使用样例uid=237733293的数据**

1. 在本地mysql中创建一个数据库:`CREATE DATABASE visualization DEFAULT CHARSET utf8 COLLATE utf8_general_ci;`

2. 将flask文件夹下的datavisualization.sql文件导入到数据库中:

1. mysql 默认以gbk编码连接数据库,导出备份文件是utf8编码,编码不一致导致出现错误

**解决**:`mysql -u root -p --default-character-set=utf8` 以utf8编码连接

2. `use visualization;`

3. `source C:\Users\76608\Desktop\Study\Subject\Program\DataVisualization\flask\datavisualization.sql`

4. source后面的地址请根据自己的路径填写

3. 在flask文件夹下的linkSQL.py文件中,根据自己的mysql修改get_conn函数的默认参数值(user, passwd, db)

4. 运行manage.py文件,打开本地连接即可

2. **使用自定义uid数据**

1. 在collect_data文件夹下修改main.py中的uid的值
2. 由于爬虫需要用的cookie是存在生存期限的,所以在爬取数据之前需要重新获取cookie更新
1. 在自己的B站个人空间中,右击鼠标选择检测或者直接F12
2. 根据1,2,3,4步骤,其中步骤2的选择不唯一,在列表中随便选择一个都可以,然后将cookie的值赋值得到(**为了复制准确,请右键cookie,选择copy value**)
3. [![zez13t.png](https://s1.ax1x.com/2022/11/17/zez13t.png)](https://imgse.com/i/zez13t)
4. 将**getfans.py, getUserInfo.py**中的headers里面的cookie的值替换为刚刚复制的cookie即可(getReview.py里的cookie可以不用改,如果爬取评论时出现连接失败,则再将其cookie修改)

3. 运行collect_data文件夹下的main.py,爬取的数据都会保存在Data文件夹下,文件夹具体包含内容如上目录
4. 在motion_classification文件夹下运行inference.py进行评论的积极消极情绪预测,其预测结果也会保存在Data文件夹下
1. 若Data文件夹下的内容需要清空,可以运行collect_data文件夹下的Trash.py统一清理Data文件夹下所有的csv文件

5. 在flask文件夹下,运行linkSQLData.py(根据自己的mysql修改get_conn函数的默认参数值user, passwd, db),将Data文件夹下的数据导入到mysql中
6. 在flask文件夹下,运行manage.py,打开本地连接即可
