Safari Reader borrows from the Readability project, according to an article in the register. Readability implements a similar user experience, but does so in a cross browser fashion (using bookmarklets)
The project site is probably a good place to start:
BTW - I had links to several sites, including the demo site, the original artcile in the register, but stackoverflow won't let n00bs post more than one link. I will edit to add those once I have some rep!
UI-level features are generally part of the Safari codebase, which as Ivo said is not open-source. The WebKit nightly builds aren't open-source either, they are essentially versions of Safari that use an embedded, trunk copy of the engine instead of the one that shipped with the OS.
It contains comparison of text extraction tools (including boilerpipe, reaability and several others) on two sets of articles. Also there is a feature wise comparison in other article on the same blog.

根据登记册中的一篇文章，Safari Reader 借鉴了 Readability 项目。 Readability 实现了类似的用户体验，但以跨浏览器的方式实现（使用书签）
该项目站点可能是一个很好的起点：
http://code.google.com/p/arc90labs-readability/
我希望这会有所帮助！
顺便说一句 - 我有几个网站的链接，包括演示网站、寄存器中的原始文章，但 stackoverflow 不会让 n00bs 发布多个链接。一旦我有一些代表，我将编辑添加这些内容！

UI 级功能通常是 Safari 代码库的一部分，正如 Ivo 所说，它不是开源的。 WebKit nightly 版本也不是开源的，它们本质上是 Safari 的版本，使用引擎的嵌入式主干副本，而不是操作系统附带的版本。

我不确定 safari 的网络阅读器代码在哪里。但有一个名为 boilerpipe 的工具可以执行非常类似的操作
I'm not sure where safari's webreader code is. but there is a tool called boilerpipe that does something very similar
Tomaz Kovacic 的博客上对可用的类似工具进行了很好的评论：http:// tomazkovacic.com/blog/122/evaluating-text-extraction-algorithms/
它包含对两组文章的文本提取工具（包括样板、可靠性等）的比较。同一博客上的其他文章中也有功能方面的比较。
