网络爬虫:Data Scraping vs Data Crawling - 新知之路

网络爬虫:Data Scraping vs Data Crawling – 新知之路

Crawling是在处理大数据时利用crawler自动获取最深层的信息,而Data Scraping是从任何资源处检索信息(并不一定是web)
Scraping数据不需要依靠网站,而是可以通过本机、数据库或网页上的“save as”链接获取信息。而网络爬虫中的crawling则代表只能通过在网页上爬取数据。有些时候相同的网页内容显示在不同的网址中,因此数据去重(data deduplication)是crawling中比较智能的一个功能。而data scraping中则不需要。crawling中最难的一件事是如何做好连续性爬取的协调关系。我们的spider在爬取时要足够有礼貌,以避免目的服务器不堪其扰而踢出spider。最后不同的crawler之间可能有冲突,但这种情况不会出现在data scraping上。
Data ScrapingData Crawling从多种资源中获取数据从网页中下载信息任何规模的数据绝大情况下是大数据不需要去重去重是必要的部分需要爬取和解析parser只需要爬取
网络爬虫是一种程序,可以自动浏览网络,它们搜寻网页上的关键字、内容和链接。这些爬虫可以有不同的名字,如bot,automatic indexer,和robot。一旦你键入一个搜索请求,这些爬虫扫描所有的包含这些词的相关网页,并返回一个巨大的索引库。比如如果你正在用Google搜索引擎,爬虫将通过服务器中索引出的结果访问指定的页面,然后取出存到Google的服务器中。网络爬虫也会顺着网站中的超链接去访问其他的网站。所以当你向搜索引擎询问“软件开发课程”时,将返回所有符合条件的页面。网络爬虫被配置成可以管理这些网页,以便生成的数据又快又新。
从图像中提取出数据,如比对相同颜色、尺寸或价格。Google Takeout可以帮助用户提取信息。这对于想要提取信息却又不想泄露自己隐私、数据的用户来说是最佳的选择。利用Google Takeout,数据挖掘工作不需要将所有的图片存储在另外的硬盘中。
用Apache Nutch进行网络爬取
Apache Nutch是一个开源网络爬虫。数据可以通过另一个Apache工具Hadoop连接在一起。可以通过这里下载。可以通过Apache Solr存储大量的数据。
Scrapy。Python的爬虫包。如果执行一些中等规模的爬虫工作,Scrapy是个不错的选择。有个特点是你可以插入一个新的函数却不影响它的核心。Storm-crawler。对于低延迟可扩展网络爬虫来说是最佳选择。这也是一个开源程序,可扩展性强,在Apache Storm上运行。Storm-crawler比Nutch好的优点是它为每一个用户的配置单独提取URL,而Nutch是分批处理。反过来Nutch的优点是前者有现成的包而后者不是。Elasticsearch River Web。这个插件是Elasticsearch的一个爬虫应用。它可以用CSS请求来爬取并提取内容。

一、安装1、安装你可以从Chrome商店(【需科学上网】 安装此扩展(Extension),安装完成后需重启 Chrome 以确保扩展加载完成。如果你不愿重启 Chrome 亦可在安装后新建的标签页(tabs)中使用此扩展。2、要求此扩展要求 Chrome 版本号 31 及以上。无操作系统限制。【欲查看 Chrome 版本,可在浏览器地址栏中输入:chromesettings/help,下图 Chrome 版本 63】二、开启 Web ScraperWeb Scraper 集成入 Chrome 开发者工具(Developer Tools)。图 1 展示了如何打开。你也可以使用以下快捷键(Shortcuts)打开 开发者工具。请在打开 开发者工具 后选中 Web Scraper 标签。快捷键:Windows,Linux:Crtl + Shift + I 或 F12,开启 开发者工具Mac:Cmd + Opt + I,开启 开发者工具开启 Web Scraper三、抓取网站打开欲抓取网站。1、建立 Sitemap欲创建 Sitemap 首先需要指定起始 URL ,这个 URL 是抓取的起点。如果抓取始于多个位置,你也可以指定多个起始 URL。比如,你想要抓取多个搜索结果,就可以为每个搜索结果建立独立的起始 URL。指定存在序列关系的多个 URL如果某个网站的页面 URL 中存在数列, 使用指定序列比使用 Link 选择器的方式抓取网页更为合理。用指定序列 [1-100] 替代 URL 中页码部分。如页码部分有 0 作为占位符可使用 [001-100]。入页码有固定间隔可使用 [0-100:10]。示例如下:1-3] 可抓取以下网页:* 001-100] 可抓取以下网页:* 0-100:10] 可抓取以下网页:* 建选择器(Selector)在创建 sitemap 后可为其添加选择器,在选择器面板可以添加新选择器、对原有选择器进行改进或浏览选择器树状结构。选择器能够以树状结构方式添加,Web Scraper 也按照此结构抓取网页。比如有一个新闻网站,你想抓取上面所有文章,这些文章都链接在网站首页。如下图示例网站:欲抓取此网站,你可以建立 Link 选择器提取首页所有文章链接。然后在添加一个 Text 选择器作为子选择器从上面的 Link 选择器指向的网页提取文章。下图展示了如何为此网站建立 sitemap:需注意,当创建选择器时需使用 Element preview 和 Data preview 功能以确保你选中了正确的网页元素及数据。更多关于选择器树状结构相关信息可在选择器文档中看到。你至少应当阅读以下核心选择器相关内容:1、文本选择器(Text selector)2、链接选择器(Link selector)3、元素选择器(Element selector)浏览选择器树状结构在为 sitemap 建立好选择器后,你可以在 Selector graph panel 浏览选择器树状结构。下图展示了一个示例选择器图。抓取网站在为 sitemap 建立选择器后可开始抓取网站。打开 Scrape 面板开始抓取。此时会打开一个网页窗口, scraper 会在其中加载网页并从中提取数据。在抓取完成后此窗口会关闭并弹出提示信息。你可以打开 Browse 面板查看抓取到的数据,并通过 Export data as CSV 面板将其导出。相关内容:Web Scraper 官方文档中文版(第 2 部分)
