c# - 解析 HTML : Adult Classification Systems

Question

我正在研究网络上使用的不同的(有时是过时的)评级/分类标准。即 PICS , POWDER , ICRA

哪个标准最受欢迎(使用它的网站数量)？

是否有一个 C# 库可以处理任何(或所有)这些？

Answer 1

你不应该再使用 PICS 了。来自 http://www.w3.org/2007/powder/ :

POWDER has superseded PICS as the recommended method for describing Web sites and building applications that act on such descriptions. A comparison of PICS and POWDER is available separately.

在链接文档中，您可以阅读:

This means that W3C does not recommend any further development of software that uses PICS, the use cases for which are covered by POWDER which offers significant advantages as detailed below.

ICRA 已 discontinued :

As of October 2010, the ICRA labeling engine has been discontinued by FOSI. Additionally, FOSI has withdrawn all support for the ICRA rating system and taken down all documentation for labeling websites with ICRA ratings. The reason is the ICRA label failed to gain widespread acceptance.

所以，我们应该使用POWDER .

但是，POWDER 只是一个框架，因此您仍然需要一个内容分级分类(即 RDF 词汇表)，您可以将其与 POWDER 一起使用。 POWDER Primer 包括 example using the ICRA vocabulary , FWIW.
