我正在寻找一种方法来获取网页的本质或最重要的方面？如果我提供 URL，是否有任何外部服务可以做到这一点？我不是在寻找 snap.com 之类的服务，因为它提供了快照。

我什至愿意自己实现这样的系统。一开始我不想付出过多的努力，而是希望能够得到一些基本的结果。关于如何解决这个问题有什么想法吗？

You can try Yahoo's Term extraction service

Update 02-May-2012

Yahoo has release a new Content Analysis Web service which will be replacing the Term extraction service. It can be invoked by syntactically sweet YQL as shown below

select * from contentanalysis.analyze where url='http://www.cnn.com/2011/11/11/world/europe/greece-main/index.html';

There is also AlchemyAPI which offers a weservice which may serve your purpose.

By snippet, do you mean like a quote that sums up the entire page you want to link to?

So if snap.com isn't a fancy, what about the entire page? For verbosity's sake? You could try out BackupURL if you want like a cache of the entire page of the site instead just a snapshot of a portion of it.
