Neo4j：BBC冠军联赛图表
2024-06-14 00:15:23
几个周末之前，我开始抓取Bern 拜仁慕尼黑/巴塞罗那比赛的BBC直播文本提要，最初只是从犯规开始，然后建立犯规图表。
从那以后，我花了更多时间，并设法对其他一些事件进行建模，包括尝试，目标，发牌和任意球。
我刚开始只是为拜仁慕尼黑/巴塞罗那比赛做这件事，但意识到扩展这一点并为2014/2015冠军联赛的每场比赛绘制图表并不是特别困难。
为此，我们首先需要下载每个匹配项的页面。 我下载了此页面，并编写了一个简单的Python脚本来获取适当的URI：
from bs4 import BeautifulSoup
from soupselect import select
import bs4soup = BeautifulSoup(open("data/results", "r"))matches = select(soup, "a.report")for match in matches:print "http://www.bbc.co.uk/%s" %(match.get("href"))然后，我将运行此脚本的输出通过管道传递到wget中：
find_all_matches.py | xargs wget -O data/raw更新抓取和导入代码以处理多个匹配相对简单。 从头到尾的整个过程如下所示：
大部分代码处于“抓取魔术”阶段，在此阶段中，我经历了所有事件并提取了可以在图中链接在一起的适当元素。
例如，任意球和犯规事件通常相邻，因此我们希望淘汰两名参与者，纸牌类型，事件时间和事件发生的比赛。
我使用Python的Beautiful Soup库完成此任务，但是没有理由您不能使用另一套工具。
README页面显示了如何创建自己的图形版本，但是这里是使用Rik的 元图查询查询图形的概述：
到目前为止，这是我最喜欢的一些查询：
哪个射门次数超过10的球员转换率最高？
