| 摘 要： | 为了方便地对大量的数字化信息进行搜索，需要新的内容描述方法。本文介绍了几个例子和原型系统，它们指明了信息可视化技术如何被应用于内容描述。信息可视化技术使可视化内容地图可以自动生成。这些地图抽取和定义信息模型、种类和作者、概念以及其它信息实体之间的关系。这些地图还支持多种多样的交互功能，用于用户探索概念关系和隐含的信息。本文还提出了关于内容测度、内容结构和内容与内容结构的可视化显示的许多问题。我们相信，理解这些问题对于信息访问语义地图是一个显著的进步。

| Abstract: | To facilitate exploration of the massive amount of digital information, new ways of content representation are required. This article presents several examples and prototype systems that show how information visualization techniques can be applied for content representation. Through the power of information visualization, visual content maps can be created automatically. These maps extract and define information patterns, categories, and relationships among authors, concepts, or other information entities. The maps also support various interactive functions for the users to explore concept relationships and the underlying information. The paper also raises many questions related to content measurement, content structures, and visual displays of content and content structures. It is believed that understanding these issues will represent a significant step toward semantic maps for information access. |
