Development of a Next-Generation Visualization Systems for Information Mining

三维计算机图形可视化在从自然科学到人文科学和社会科学的广泛学科中有效理解目标对象的复杂结构和行为方面起着不可或缺的作用。模块化可视化环境（Modular Visualization Environments，MVE）是一种基于可视化和非过程化编程思想的模块化可视化环境，被认为是现代可视化系统的设计标准。然而，对于一般用户来说，选择和连接预存储的模块来创建有效的应用网络是一项困难的任务，因为他们不是可视化专家，并且不知道如何将他们的数据集映射到最佳的图形形式。在这项研究中，一个新的MVE，称为GADGET，已被开发，它利用可视化专家的知识和专业知识，以帮助用户设计模块网络根据他/她的可视化目标。此外，通过开发一个基于MVE的工作台，称为MWMD，用于支持复杂的多媒体数据库查询的设计和一个特定的信息可视化系统的校园局域网流量管理，丰富的知识存储已经获得了计算出下一代可视化系统的信息挖掘。

Three-dimensional computer graphics visualization plays an indispensable role in effective understanding of complex structure and behavior of target objects in the wide spectrum of disciplines ranging from natural sciences, to humanities and social science. Modular visualization environments (MVEs), which are based on the dataflow paradigm allowing for visual and non-procedural programming, are viewed as the de fact standard of contemporary visualization system. However, it is a difficult task for the general users to select and connect pre-stored modules to create effective application networks, since they are not visualization experts, and do not know how to map their datasets to best graphical forms. In this research, a new MVE, called GADGET, has been developed, which utilizes the set of visualization experts' knowledge and expertise to assist the user to design module networks according to his/her visualization goals. In addition, through the development of an MVE-based workbench, called MWMD, for supporting the design of complex multimedia database queries and a specific information visualization system for campus LAN traffic management, a rich store of knowledge has been obtained to figure out the next- generation visualization system for information mining.
