万维网为何如此流行?不仅仅因为它能够提供多媒体信息,更因为它具有超文本特性。超文本是包含与其他数据的链接的数据,难以用普通的文本来衡量。在超文本世界里,信息是根据相互间的联系来组织的,它允许同一套资料同时以多种方式编排。实际上,不同信息间的相互关系往往比信息本身更有价值。 Why is the World Wide Web popular? Not only because it can provide multimedia information, but also because of its hypertext features. Hypertext is data that contains links to other data that is hard to measure in plain text. In the hypertext world, information is organized based on mutual relations, which allows the same set of materials to be simultaneously orchestrated in many ways. In fact, the interrelationship between different information is often more valuable than the information itself.
