摘要

空间超文本系统的发展是由降低用户表达努力的需求驱动的。用户通过信息对象的视觉相似性和共定位来表达类别和相互关系。改变视觉属性或移动对象的便利性使空间超文本更适合于信息不断发展的任务。但是,这种结构的隐含性质给作者和读者不是同一群人的任务带来了挑战。视觉知识构建器(VKB)包括早期空间超文本的轻松表达,同时增加了对长期协作和需要明确链接的任务的更大支持。VKB包括一个历史机制,用于记录空间超文本和本地、全局和历史链接的演变,以便在信息块之间进行明确的导航连接。添加到VKB中的机制使空间超文本适用于更广泛的任务。特别是,VKB的全球链接使使用Internet现有基础设施的广域分布式空间超文本成为可能。VKB的版本已经使用了两年,用于记录、写作、项目管理和会议组织等任务。

The visual knowledge builder: a second generation spatial hypertext
The development of spatial hypertext systems was driven by the need to lower users' effort of expression. Users express categories and interrelationships through the visual similarity and co-location of information objects. The ease of changing a visual property or moving an object makes spatial hypertext better suited to tasks where the information continually evolves. But the implicit nature of the structure poses challenges for tasks in which the authors and readers are not the same set of people. The Visual Knowledge Builder (VKB) includes the ease of expression of earlier spatial hypertexts while adding greater support for long-term collaboration and tasks requiring explicit links. VKB includes a history mechanism that records the evolution of the spatial hypertext and local, global, and historical links for explicit navigational connections between chunks of information. The mechanisms added to VKB make spatial hypertext applicable in a much wider variety of tasks. In particular, VKB's global links enable wide-area distributed spatial hypertext using the existing infrastructure of the Internet. Versions of VKB have been in use for two years in tasks including note taking, writing, project management, and conference organization.
