  Knowledge visualization - Wikipedia, the free encyclopedia
Knowledge Visualization aims to improve the transfer of knowledge by using computer and non-computer-based visuals complementary.
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.
Knowledge Visualization has its roots in Pedagogy, Cognitive Psychology Graphic Design Visual Communication, Communication Sciences, 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.

The term knowledge is also used to mean the confident understanding of a subject, potentially with the ability to use it for a specific purpose.
Knowledge management seeks to understand the way in which knowledge is used and traded within organisations and treats knowledge as self-referential and recursive.
Knowledge is a term with many meanings depending on context, but is as a rule closely related to such concepts as information, communication, meaning, instruction, representation, learning and mental stimulus.

 Knowledge management - Wikipedia, the free encyclopedia
Knowledge management programs are typically tied to specific organizational objectives and are intended to lead to the achievement of specific targeted results such as improved performance, competitive advantage, or higher levels of innovation.
One alternative strategy to encoding knowledge into and retrieving knowledge from a knowledge repository such as a database is for individuals to instead access expert individuals on an ad hoc basis, as needed, with their knowledge requests.
Knowledge Management activities may be centralised in a Knowledge Management Office (KMO), or responsibility for Knowledge Management may be located in existing departmental functions, such as the HR or IT departments.

 Scientific visualization - Wikipedia, the free encyclopedia
Scientific- (or data-), and Information visualization are branches of computer graphics and user interface which are concerned with the presentation of interactive or animated digital images to users to understand data.
Visual analytics is especially concerned with sensemaking and reasoning.The distinction between "natural" and complex data structures, however is blurred, keeping in mind that graphs can in general represented by adjacency matrices.
Visualization, in the presentation sense, is not a new phenomenon.

 Ontology-Driven Visualization
Visualization of time-oriented data requires knowledge about temporal properties of the data (e.g., persistence of states when data are not sampled continuously, to create meningful discrete, interval-based characterizations of the data).
The knowledge which temporal-granularity ranges are meaningful for each parameter in each context, and what aggregation operators should be used automatically when the granularity chosen is out of that range, is acquired and added to the domain model as part of the visualization knowledge.
The visualization and navigation modules of the KNAVE architecture and the inference structure underlying them can be viewed as part of a new problem-solving method, specific to the task of visualization of and navigation through time-oriented data and its temporal abstractions.

 Visualizing a Knowledge Domain's Intellectual Structure   (Site not responding. Last check: 2007-10-13)
To make knowledge visualizations clear and easy to interpret, the authors have developed a method that extends and transforms traditional author co-citation analysis (ACA) by extracting structural patterns from the scientific literature and representing them in a 3D knowledge landscape.
It also integrates Pathfinder and factor analysis to visualize specialties in the underlying domain knowledge and visualizes the citation frequency of scientists to track changes in their influence over time.
This knowledge visualization approach identifies intellectual groupings based on extending the traditional ACA, augmenting the existing document- and concept-centered approaches to knowledge visualization.

 Literature Review on Visualization
Finally visualization tools that can be used analyze and display various aspects of the modeled traffic flow data such as shortest paths, travel time, flow compositions on a network in user-equilibrium is described.
Visual variables and time display: It uses seven variables defined by Bertin (1983) – these are position, size, value, texture, hue, orientation and shape.
These are: 1) the speed of graphical rendering, 2) the management of perceptual anomalies due to visual combination effects, 3) the vast range of potential approaches and mappings (the complexity of the visual assignment process), and 4) the orientation of the user into an artificial or virtual reality.

Knowledge and libraries - this conceptual symbiosis is as old as the idea of libraries itself: Libraries collect artifacts of explicated knowledge and make them available for building up new knowledge in all areas of everyday life.
Using triggers to update an information visualization client has the advantage that no unnecessary database requests have to be made and that the delay in updating the information visualization on the client side is only dependent on the time it takes to send a message from the server to the client.
Furthermore, the visualization of the hall and stands could be used as a metaphor to access further information about the exhibitors and their products, or to send requests for meeting appointments to staff members of the exhibitors.

 Mapping Scientific Frontiers: The Quest for Knowledge Visualization
Visualization of scientific frontiers is a relatively new field, yet it has a long history and many predecessors.
The last two chapters finally answer the question—"What does a scientific paradigm look like?" The visual answer given is specific to the GSA technique used by Chen, but does satisfy the intent of the book—to introduce a way to visually identify scientific frontiers.
This combination of visual maps and expert knowledge, used jointly to good effect in the book, becomes a potent means for explaining progress in science to the expert and non-expert alike.

Knowledge domain visualization (KDV) assists in recognizing patterns of citation, not only in scientific journals but also in how organizations, industries, and the world at large refer to each other and give attribution or citation.
Being a "visual" type, I find this area of study into visualizing a knowledge domain's intellectual structure in a three-dimensional spatial model compelling.

 visualization
The goal of this integration is visually enabled knowledge construction tools that facilitate both the process of uncovering patterns and relationships in complex data and subsequent explanation of those patterns and relationships.
Other specific challenges are: to understand the process of visually facilitated knowledge construction (and the impact of visual and other characteristics of the analysis environment on that process); and to develop mechanisms that facilitate productive collaboration in knowledge construction among human experts and between human users and computational agents.
For advances in visual representation and visually enabled knowledge construction to have the greatest impact, and to extend these methods beyond use by individual experts, complementary advances are required in geovisualization interface design.

While one would hope that the wealth of data would be an asset, too often the reverse is true: the volume of data simply serves to confuse and paralyze a person in a decision-making process.
Understanding information visualization requires a person to learn about basic multivariate data characterizations, visual properties such as color and animation, general visualization techniques, and existing information visualization tools and systems.
While one can argue that information visualizations can be found all the way back to the dawn of human-kind, the use of computer-based interfaces and visualizations for helping to understand data is a fairly recent development.

Knowledge engineering is often a complex area for end-user and engineer alike.
We anticipate the workshop will be of interest to several groups: * professionals interested in improving knowledge capture technology, particularly in the areas of tool adoption and usability; * developers of information visualization solutions to knowledge engineering domains; * people with interests in the area of cognitive support for complex tasks.
For example, a researcher who has created a knowledge sketching tool will be interested to discover how this tool may be combined with information visualization techniques in order to improve the usability and utility of the tool for the end-user.
