"Knowledge mapping " is a general term that covers:
+ mapping public issues ("social messes," "wicked problems" e.g., Robert Horn)
+ mind maps (e.g., Inspiration software)
+ pattern languages (e.g., Christopher Alexander)
+ DialogueMapping (e.g., CogNexus Institute)

+ and all other forms of visual presentation of information, especially of relationships (e.g. Edward Tufte) : http://www.siliconyogi.com/andreas/it_professional/sol7/EmergentLearningMaps.html

Visualizing a dynamic knowledge map using Semantic Web technology : http://www.semtalk.com/pub/KimFillies.htm
Unlike a chemistry model where only physically adjacent nodes (atoms) can be connected, in a semantic network any two nodes (concepts) may be connected — regardless of how far away they may be from each other. The challenge in this scenario is to present a meaningful visualization of the underlying knowledge structure while providing intuitive understanding, eliminating visual clutter and maintaining aesthetic appeal. http://www.semanticresearch.com/semantic/visualization.php Clicking on any of the related concepts will navigate to that concept as the central concept, displaying a new graphic frame.

Pedro Talks With God
Pedro was driving down the street in a sweat because he had an important meeting and couldn't find a parking place.
Looking up toward heaven, he said "Lord, take pity on me. If you find me a parking place I will go to Mass every Sunday for the rest of my life and give up tequila."
Miraculously, a parking place appeared.
Pedro looked up again and said "Never mind. I found one."
