在本文中，我们介绍了一种集成的空间超文本开发方法。该方法结合了语义结构的几种理论和技术，简化了从隐式语义结构到虚拟现实中呈现的语义空间的转换。在同一个语义空间中，浏览和查询成为自然的、固有的和兼容的活动。总体设计原则以认知地图理论为基础。潜在语义索引、探路者网络缩放和虚拟现实建模等技术被和谐使用。根据最近的一项实证研究的初步结果，讨论了这种综合方法的价值，该研究表明，空间隐喻是直观的，在处理隐含的信息结构时特别有用，或者当需要一个高度灵活和可扩展的虚拟环境时。文中还讨论了与空间超文本相关的搜索策略和进一步的工作。
In this paper, we introduce an integrated approach to the development of spatial hypertext. This approach brings together several theories and techniques concerning semantic structures, and streamlines the transformation from implicit semantic structures to a semantic space rendered in virtual reality. Browsing and querying become natural, inherent, and compatible activities within the same semantic space. The overall design principle is based on the theory of cognitive maps. Techniques such as latent semantic indexing, Pathfinder network scaling, and virtual reality modelling are used in harmony. The value of this integrated approach is discussed based on initial results of a recent empirical study, which suggests that the spatial metaphor is intuitive and particularly useful when dealing with implicit information structures, or when a highly flexible and extensible virtual environment is required. Search strategies in association with the spatial hypertext and further work are also discussed.
