ABSTRACT
留学生论文网 Knowledge workers who want to apply knowledge visualization have to determine which visualization tool is suitable for their needs. To support knowledge workers in this sophisticated problem a systematic approach is presented that matches typical tasks in knowledge management to visualization techniques that support these tasks. Knowledge workers are provided with a three-dimensional decision matrix that enables them to easily identify a suitable visualization technique for a certain knowledge problem. To be able to systematically evaluate and identify adequate visualization techniques a set of evaluation criteria is introduced.
KEY WORDS
Information visualization, knowledge visualization, knowledge management, visualization technique
1. Introduction
Information visualization supports knowledge workers in creation, verification and presentation of knowledge as well as sharing knowledge with others. For example, it assists them in understanding social relationships, financial trends, document library development, and many more [1]. While information visualization ([2], [3], [4], [5]) is a well established field of study a new discipline is forming dealing with visualization techniques utilized for performing tasks of knowledge management – denoted as knowledge visualization (KV).
Eppler and Burkhard define knowledge visualization as the use of visual representations to improve the creation and transfer of knowledge between at least two persons [6]. Knowledge visualization is characterized by its multidisciplinary approach since it integrates results from information visualization, cognitive art, communication science, information architecture and knowledge management [7]. Knowledge visualization is an emerging discipline of information visualization and still has to be defined and established [8].
Information visualization – and consequently knowledge visualization – provides knowledge managers with a large variety of visualization techniques and tools that might be applied. However, knowledge managers think in terms of the knowledge management tasks they have to fulfil or in terms of the recipients, but not in visualization terms. For several knowledge management tasks the visualization of knowledge can be extremely helpful, for others it is not. In those cases where visualization can be applied, due to the large number of potential visualization techniques provided by information visualization ([2], [3], [4]) it is difficult to identify the one that suits best. This paper aims at supporting knowledge managers in solving this problem.
