In general, an automatic conversion is not possible, since HTML says what something looks like, and not what it means. If the HTML contains existing markup, you could use Anything2Triples (http://developers.any23.org/) to get RDF out.
If it's just HTML you have to write your own extraction rules somehow. GRDDL would work, but I would probably simply use python + BeautifulSoup. It depends what technology/language you know already!
如果 HTML 包含嵌入的 RDFa，您可以使用 RDFa 解析器来提取信息。有适用于各种平台和语言的解析器，因此取决于您的开发环境。

一般来说，自动转换是不可能的，因为 HTML 说明了某些内容的外观，而不是它的含义。如果 HTML 包含现有标记，您可以使用 Anything2Triples (http://developers.any23.org/) 来获取 RDF。
如果它只是 HTML，您必须以某种方式编写自己的提取规则。 GRDDL 可以工作，但我可能会简单地使用 python + BeautifulSoup。这取决于您已经掌握的技术/语言！
