VLearn 3D
The figure illustrates the temporal-spatial distribution of attendees
during the six hour virtual Conference on Learning in Three Dimensions,
VLearn3D 2002.
The eight major conference worlds are represented by square, perspective
maps, each labeled by its name. Worlds accessed at the beginning of the
conference are placed at the bottom, worlds accessed later toward the
top. Next to each world is a circular snapshot of the virtual venue. Short
descriptions of the main sessions are added as text.
Overlaid on each map are the trails of conference attendees recorded during
the event. Major jumps between worlds are visualized by transparent lines.
The thickness of each line corresponds to the number of traveling users.
Color coding was used to denote the chronological paths of the conference
sessions. The trail of Bonnie DeVarco, the main organizer of the Conference,
is given in white.
The developed visualization tools are intended to support social navigation,
the evaluation and optimization of three-dimensional virtual worlds, and
the study of their evolving communities.
User position data recorded during real world events via motion sensors,
RFID tags, or global position sensors can be visualized and studied in
a similar fashion.
The work was selected as a semifinalist in the international Science
and Engineering Visualization Challenge 2003 organized by NSF
and Science.

Avatars 2002
The visualization tools described above been applied to map and evaluate
numerous educational environments, collaborative information visualization
environments and conferences such as Avatars
2002. The map displays user trails recorded in the Art world during
the conference. More figures.
Bruce Damer, July 2003: "Gosh there has been nothing done like
this yet, this is a new high watermark for our field."

Quest Atlantis
The visualization tools described above been applied to map diverse
worlds in the Quest Atlantis Universe.
The map displays user trails.
This
work is featured in the Atlas
of Cyberspaces.

The visualization tools described above been applied to map Linkworld in Active Worlds AWEDU. The map displays users chat and click activity.

Mapping Social
Diffusion Patterns
A visualization tool set that can be used to visualize the evolution of
three dimensional virtual environments, the distribution of their virtual
inhabitants over time and space, the formation and diffusion of groups,
the influence of group leaders, and the environmental and social influences
on chat and diffusion patterns for small (1-100 participants) but also
rather large user groups (more than 100 participants) is presented.

Advanced data mining and information visualization techniques can be applied to support science and technology management. Large amounts of, e.g., publication, patent, and grant data are analyzed, correlated, and visualized to map the semantic space of researchers, publications, funding, etc.. The resulting visualizations can be utilized to objectively identify major research areas, experts, institutions, grants, publications, journals, etc. in a research area of interest. In addition, they can assist identify interconnections, the import and export of research between fields, the dynamics (speed of growth, diversification) of scientific fields, scientific and social networks, and the impact of strategic and applied research funding programs among others.

Review of Research
on Visualizing Knowledge Domains
Using a tutorial
style, various algorithms were applied to map papers related to 'Visualizing
Knowledge Domain' research, the so called ARIST data set. Never before
have so many knowledge domain maping algorithms been applied to one data
set. More figures.

Mapping Aging Research
This research aims to analyze and visualize the impact of governmental
funding on the amount and quality of research publications. For the first
time, grant and publication data appear interlinked in one map. Resulting
visualizations show an information landscape of aging-related data -
providing NIH with a tool to discover general patterns and trends.

The Simultaneous Evolution of Author and Paper Networks
The TARL model attempts to capture the roles of authors and papers
in the production,
storage, and dissemination of knowledge. It incorporates (1) a partitioning
of authors and papers into topics, (2) aging, i.e., a bias for authors
to cite recent papers, and (3) a tendency for authors to cite papers cited
by papers that they have read resulting in a rich get richer effect.

Mapping Topics and Topic Bursts in PNAS
This work demonstrates an approach to map the dynamics of scientific
knowledge via analysis of the complete set of papers published in the
Proceedings of the National Academy of Science (PNAS) in the years 1982-2001.
Data analysis techniques are applied to citation data within this corpus
to analyze and visualize highly frequent words as well as sudden increases
in the usage patterns of words, called ‘bursts’.

Studying the Emerging Global Brain
The increasing specialization of researchers and practitioners, the accelerated
speed of scientific progress and the need to collaborate across institutional
and disciplinary boundaries is fostering the formation of high-impact
co-authorship teams. We present novel methods to analyze and visualize
the size, interconnections and impact of co-author teams over time. The
methods were applied to examine the evolution of a 31-year publication
dataset that captures the emergence of Information Visualization as a
scientific field. The results indicate the development of a more interdisciplinary,
globally connected science as opposed to science driven by single experts.
