---------------------------------------------------------------------------

Diagrams 2000 is the first event in a new interdisciplinary conference
series on the Theory and Application of Diagrams.

Driven by the pervasiveness of diagrams in human communication and by
the increasing availability of graphical environments in computerised
work, the study of diagrammatic notations is emerging as a research
field in its own right. This development has simultaneously taken
place in several scientific disciplines, including, amonst others:
cognitive science, artificial intelligence and computer science.
Consequently, a number of different workshop series on this topic have
successfully been organised during the last few years: Thinking with
Diagrams, Theory of Visual Languages, Reasoning with Diagrammatic
Representations, and Formalizing Reasoning with Visual and
Diagrammatic Representations.

Diagrams are simultaneously complex cognitive phenonema and
sophisticated computational artifacts. So, to be successful and
relevant the study of diagrams must as a whole be interdisciplinary in
nature. Thus, the workshop series mentioned above have decided to
merge into Diagrams 2000, as the single interdisciplinary conference
for this exciting new field. Diagrams 2000 provides a forum with
sufficient breadth of scope to encompass researchers from all academic
areas who are studying the nature of diagrammatic representations and
their use by humans and in machines. It is intended to become the
premier international conference series in this field and will attract
participants from applied linguistics, architecture, artificial
intelligence, cognitive science, computer science, education, graphic
design, history of science, human-computer interaction, philosophical
logic, psychology and others.

The conference will consist of technical sessions with presentations
of refereed papers and tutorials which are intended to bridge the gap
between the various disciplines and foster the development of a common
language.

Some examples of the broad topics and issues that papers might cover
are:

* psychological/educational investigations of how people reason or
  learn with diagrams;
* computational reasoning with and interpretation of diagrams;
* usability issues concerning diagrams;
* classification and formalization of abstract properties of diagrams;
* descriptions of particular diagramming notations and their use.

We invite submissions of research papers that focus primarily on
diagrams or diagram use by human or computer. Other than this, there
are no particular restrictions on the field of study or the specific
topics of the papers. The papers will be peer reviewed. It is planned
to publish the proceedings as a volume in the Springer series Lecture
Notes in Artificial Intelligence.

Appropriate research methodologies and approaches include, amongst
others: experimental investigation; rigorous empirical observation and
analysis; computational modelling of the processes of reasoning with
diagrams; implementation of systems deploying diagrams; knowledge
accumulated from reflection on extensive practice; analysis of a
particular diagramming notation; mathematical proofs of complexity and
expressiveness of classes of diagrams.
