Visualization

Visualization tools are designed to help organize and display large amounts of bibliometric (or other) data in ways which promote understanding and insight.

VxInsight is a research tool conceived and developed at Sandia National Laboratories.

VxInsight

VxInsight uses topographical landscapes to visualize data. Mountains represent collections of

bibliometric data (citations) which are similar.

Large mountain = lots of citations small mountain = fewer citations nearby mountains = some similarity far away mountains = little similarity

VxInsight Visualization Process

Bibliometric data is mined based on key words, phrases, patents, authors, etc.

A “similarity function” must be defined quantitatively defines how “similar” each

pair of bibliometric entries are shared keywords referencing etc.

similarity functions are user defined

VxInsight Visualization Process

VxInsight then uses a scheme which combines an attractive force (based on similarity) and a repulsive force (based on density) to “ordinate” the citations. Forming:

mountains valleys plains ridges

VxInsightExample

Let’s take a look at an example. These displays have been modified

and “sterilized” to protect the proprietary nature of the analysis.

Copies of the VxInsight slides are not available on the web site.

Assume the keywords were acid, soluble, copolymer
