Introduction
------------------------------------------------------------------------

We solicit papers, posters, and contest entries for InfoVis 2003, the
ninth annual IEEE Symposium on Information Visualization. InfoVis is
the primary meeting in the field of information visualization, and is
held in conjunction with the IEEE Visualization 2003 (Vis03) conference.

Computer-based information visualization, or "infovis", centers around
helping people explore or explain data by designing interactive
software that exploits the capabilities of the human perceptual system.
The central design challenge in infovis is designing a cognitively
useful spatial mapping of a dataset that is not inherently spatial.
There are many possible visual encodings, only a fraction of which are
helpful for a given task. We draw on the intellectual history of
several traditions, including computer graphics, human-computer
interaction, cognitive psychology, semiotics, graphic design,
statistical graphics, cartography, and art. The synthesis of relevant
ideas from these fields with new methodologies and techniques made
possible by interactive computation are critical for helping people
keep pace with the torrents of data confronting them. One of the few
resources increasing faster than the speed of computer hardware is the
amount of data to be processed.

We encourage submissions of papers (31 Mar 03 deadline), interactive
posters (1 Aug 03 deadline), and InfoVis Contest entries (1 Aug 03
deadline). We encourage the use of digital video to support the
submission, particularly if part or all of the work covers interactive
techniques.

 =======================================================================

Papers: due Mon 31 March 2003 5:00pm PST
------------------------------------------------------------------------

We solicit papers in five categories: technique, system, design study,
evaluation, and model. Although many papers might include elements of
more than one of these categories, for the purposes of reviewing you
will be asked to decide which best fits your submission.

Technique

Technique papers introduce novel techniques or algorithms that have
not previously appeared in the literature. We also welcome papers that
significantly extend techniques or algorithms that have been
previously presented, for example by scaling to datasets of much
larger size than before or by generalizing a technique to a larger
class of uses.

The technique or algorithm description provided in the paper should be
complete enough that a competent graduate student in visualization
could implement the work, and the authors should create a prototype
implementation of the methods. Relevant previous work must be
referenced, and the advantage of the new methods over it should be
clearly demonstrated. There should be a discussion of the tasks and
datasets for which this new method is appropriate, and its
limitations. Evaluation through informal or formal user studies, or
other methods, will often serve to strengthen the paper, but are not
mandatory.

Past work that would fall into this category includes: algorithms for
layout and navigation of trees, graphs, and networks; interaction
techniques for infovis; browsing and navigation techniques in large
information spaces; geometric or graphics algorithms for increased
scalability of existing techniques; and techniques for visualizing
very high dimensional (100+ D) spaces. This list is not exclusive, and
we welcome submissions in these and all other areas of infovis.

System

System papers present a blend of algorithms, technical requirements,
user requirements, and design that solves a major problem. The system
that is described is both novel and important, and it has been
implemented. The rationale for significant design decisions is
provided, and the system is compared to documented, best-of-breed
systems already in use. The comparison includes specific discussion of
how the described system differs from and is, in some significant
respects, superior to those systems. For example, the proposal may
offer substantial advancements in the performance or usability of
infovis systems, or novel capabilities. Every effort should be made to
eliminate external factors (such as advances in processor performance,
memory sizes or operating system features) that would affect this
comparison. For further suggestions, please review "How (and How Not)
to Write a Good Systems Paper" by Roy Levin and David Redell at
http://www.acm.org/sigops/advice.html, and "Empirical Methods in CS
and AI" by Toby Walsh at
http://www-users.cs.york.ac.uk/~tw/empirical.html


Design Study

Design study papers explore the choices made when applying infovis
techniques in an application area, for example relating the visual
encodings and interaction techniques to the requirements of the target
task. Although a limited amount of application domain background
information can be useful to provide a framing context in which to
discuss the specifics of the target task, the primary focus of the
case study must be the infovis content. Describing new techniques and
algorithms developed to solve the target problem will strengthen a
design study paper, but the requirements for novelty are less
stringent than in a Technique paper. The work will be judged by the
design lessons learned, and on which future contributors can build.
We invite submissions on any application area. In past years
these areas have included bioinformatics, data mining and databases,
finance and commerce, telecommunications and networking, information
retrieval from large text corpora, and computer-supported
cooperative work (CSCW). This year we particularly encourage submissions
in the application area of software engineering, a shared focus with
our Vis 03 parent conference.


Evaluation

Evaluation papers are an empirical comparative study of infovis
techniques or systems. Authors are not necessarily expected to
implement the systems used in these studies themselves; the research
contribution will be judged on the validity and importance of the
experimental results as opposed to the novelty of the systems or
techniques under study. The conference committee appreciates the
difficulty and importance of designing and performing rigorous
experiments, including the definition of appropriate hypotheses,
tasks, data sets, selection of subjects, measurement, validation and
conclusions. The goal of such efforts should be to move from mere
description of experiments, toward prediction and explanation. We do
suggest that potential authors who have not had formal training in the
design of experiments involving human subjects may wish to partner
with a colleague from an area such as psychology or human-computer
interaction who has experience with designing rigorous experimental
protocols and statistical analysis of the resulting data.


Model

Model papers present new interpretations of the foundational theory of
information visualization. Example of past work in this area are
taxonomies, extensions to Bertin's theories of visual encoding,
analysis of metaphors, perception, cognitive models, visual
comparisons and indications of causality. Implementations are usually
not relevant for papers in this category. Papers should focus on basic
advancement in our understanding of how infovis techniques complement
and exploit properties of human vision and cognition.

------------------------------------------------------------------------
Papers Review Process
------------------------------------------------------------------------

The length of the paper should be commensurate with its contributions,
up to a maximum of eight (8) pages. For example, a useful idea
presented completely and concisely in four pages is more likely to be
accepted than the same idea presented in eight pages. The length limit
includes figures, which may be in color because the proceedings will
be printed in full color throughout. See the InfoVis 03 Submissions page
(http://www.infovis.org/infovis2003/submit.shtml) for details on format and
electronic submission of papers and optional accompanying digital
video.

Papers are peer-reviewed, and this year we are moving to a two-tier
reviewing model. The program committee will consist of senior
reviewers who will recruit additional external reviewers. Each paper
will be read by two senior reviewers on the program committee and two
additional external reviewers. A paper may be accepted under the
condition that its length is decreased.

All papers submitted to InfoVis03 must be original, unpublished work.
Any paper that has been previously published in equivalent or
substantially similar form by any other conference or in any other
journal will be rejected at an early stage of the review process, as
will papers that are simultaneously submitted to InfoVis03 and to any
other conference or journal. A paper is considered published if it has
appeared in a peer-reviewed journal or in published meeting
proceedings that are commercially available afterward to nonattendees.
Note that work described in the Interactive Posters or Late-Breaking
Hot Topics venues from previous InfoVis symposia is thus not
considered formally published, and you are free to submit work based
on that core (although it's unlikely to be accepted unless you've made
substantial progress since then).

Submissions are treated as confidential communications during the
review process, so submission does not constitute public disclosure of
any ideas therein. Submissions should contain no information or
materials that will be proprietary or confidential at the time of
publication (19 October 2003), and should cite no publications that
are proprietary or confidential at the time of publication.



 =======================================================================
Posters: due Fri 1 Aug 2003 5:00pm PST
------------------------------------------------------------------------

The interactive poster category includes both traditional posters and
demonstrations of interactive systems, either live on a laptop or
through video. We encourage both submissions of original unpublished
work and submissions showcasing systems of interest to the information
visualization community that have been presented in other venues.
Accepted posters will be included electronically on the IEEE
Visualization 2003 Conference DVD, placed on the official infovis.org
web site, and also distributed in a hardcopy compendium to all
symposium and conference attendees.

All authors of accepted interactive posters are required to bring an
explanatory hardcopy poster for display during the scheduled evening
poster session, and be available for discussion at that time. Accepted
authors who wish to also show demos of their work are encouraged to
also bring a laptop to the poster session. There will be a limited
number of stations for showing videos during the main poster
session. Authors who wish to show a live demo but cannot provide their
own machine should contact the posters chairs in advance of the
submission deadline to discuss the logistics. All authors who plan to
show live demos or video should clearly indicate this fact in their
submissions. Authors are also required to present a very brief summary
(1-3 powerpoint slides) of their interactive poster at a short preview
session earlier in the day.

Interactive poster authors must submit a 2 page summary, in two-column
SIGGRAPH format as described <a href="#papersubmit">above</a> for
papers. Those who intend to show demos are highly encouraged to also
submit an accompanying video. Clearly identify the type of your
submission by including the prefix "Interactive Poster:" in the title
of your summary.

------------------------------------------------------------------------
Posters Review Process
------------------------------------------------------------------------

Each poster will be read and evaluated by both of the Posters
Chairs.  Submissions will be evaluated based on whether the content
is suitable for the venue and is not a repetition of the work of
others.  Authors of posters that are not accepted will receive summary
reviews of their poster from the chairs explaining the decision and
providing feedback.

See the InfoVis 03 Submissions page
(http://www.infovis.org/infovis2003/submit.shtml) for details on format and
electronic submission of posters and optional accompanying digital
video.

 =======================================================================
Contest: due Fri 1 Aug 2003 5:00pm PST
------------------------------------------------------------------------

Our goal in organizing this new participation category is to initiate
the development of benchmarks for information visualization, establish
a forum to promote evaluation methods, and create a new interesting
event at the conference.

For Infovis 2003 we are inviting the submissions of case studies of
the use of information visualization for pairwise comparison of trees.
Several pairs of datasets will be provided February 1st, along with a
description of the data and open-ended tasks. Contest entries will
consist of a 2-page summary, a video and accompanying materials. First
place entries will receive a prize and will have a speaking slot to
present their work during the contest session at the conference.
Second place entries will present a contest poster. (Note that
duplicate submissions should *not* be made to both the poster and
contest categories.) All accepted entry materials will be made
available online after the conference.

 =======================================================================
Presenter Requirements
------------------------------------------------------------------------

Submission of a paper, poster, or contest entry is considered a
commitment for at least one author to register and attend the
conference as a presenter if the work is accepted. In the case that
extraordinary circumstances arise that prevent an author from
personally presenting the work, it is the author's responsibility to
arrange in advance for an alternate presenter.

We are unable to subsidize registration or travel costs for
presenters. InfoVis is a nonprofit symposium run by volunteers, and
could not survive without the financial support of authors and
organizers alike.
