Knowledge visualization

Knowledge visualization is a young scientific discipline. It was introduced as "the use of visual representations to transfer knowledge between at least two persons" (Burkhard and Meier, 2004). Knowledge Visualization aims to improve the transfer of knowledge by using computer and non-computerbased visualization methods complementary. Examples of such visual formats are sketches, diagrams, images, objects, interactive visualizations, information visualization applications, imaginary visualizations, stories.

While information visualization concentrates on the use of computer-supported tools to explore large amount of abstract data, knowledge visualization focuses on the transfer of knowledge among persons. Beyond the mere transfer of facts, knowledge visualization aims to further transfer insights, experiences, attitudes, values, expectations, perspectives, opinions, and predictions by using various complementary visualizations. Dynamic forms of visualisation such as educational animation have the potential to enhance understandings of systems that change over time.

Knowledge Visualization has its roots in Graphic Design Visual Communication, Communication Sciences, Visual Perception and Knowledge Management, where it is a key-issue to make knowledge visible so that it can be better identified, accessed, shared, discussed, applied, or generally be managed. A method proposed by researchers uses time description language and timescapes which lead to time-technologies that make knowledge visualization possible, especially for artificial intelligence agents.
