Abstract

The rapid development of information technology has sped up the production of digital news media. An effective news production system plays an important role in improving workflow efficiency of the production via computer support collaborative work. However, most news production systems developed today target for on-line news Web publishing and usually are tailored to a specific organization. In this paper, we have used the University News at National Chengchi University as a target example to design a generic collaborative news production system with flexible access control. We have formally analyzed and modeled the system requirements with the UML language. In addition, we have adopted an augmented role-based access control mechanism to design a news production system that can easily adapt to organizational changes. The implemented system is used a testbed for experimental news production. Preliminary evaluation of the system functions reveals that users can adapt to this system and increase their productivity in the news production process.

具有灵活的基于角色的访问控制的实验性新闻制作系统

信息技术的飞速发展，加速了数字新闻媒体的产生。一个有效的新闻制作系统通过计算机支持协同工作，对提高新闻制作的工作流程效率具有重要作用。然而，今天开发的大多数新闻制作系统都是针对在线新闻Web发布的，并且通常是为特定的组织量身定制的。本文以国立政治大学校报为例，设计了一个具有灵活访问控制的通用协同新闻生产系统。我们已经用UML语言对系统需求进行了正式的分析和建模。此外，我们还采用了一种增强的基于角色的访问控制机制来设计一个能够轻松适应组织变化的新闻生产系统。所实现的系统作为实验新闻制作的试验台。对系统功能的初步评估表明，用户能够适应该系统，提高新闻生产过程中的工作效率。
