Hi Gary,
I may drive up and back that Friday since
it is always an informative treat to hear Pat.
This would be great! From what I know, Todd may also come.
Pat's talk will be from around 4-5:30pm at 112 Walker Building,
University Park and there will be a reception from 3-4pm before the
talk in 319 Walker. We will also have another get-together at around
8:30pm at the home of our Department's head (I would have to check
back with the Karl before). Pat will be staying at Penn State for 3
days - just let me know if you would like to meet with him on Friday
before the talk and I can try to arrange something. This may also be
a good opportunity to talk to Fred Fonseca
(http://www.personal.psu.edu/fuf1/) about his geo-ontology research.
If we returned around 7-8 we would be back
at my house before midnight. Mapquest says that it is 3
hrs 35 mins / 198.86 miles
State College to Washington DC usually takes me about 3:30 and I am
not a fast driver.
Best,
Jano

Is there a dinner after the talk?
If there are 1-3 people in the DC area that would like to share
the ride in my hybrid, they could contact me (info below). I
live in the Potomac/Rockviile MD area and would be traveling up
270 to PA between 10 and 11 so to get to PSU by 3 or so with a
stop for lunch. I am near the Red line and could pick folks up
there if they use Metro.

Dear all,
Pat Hayes will visit us next week for 3 days and will give a
talk on
'Semantics for Cartography'. As his work has been very
influential for
geo-semantics and the Semantic Web in general, I am attaching
a short
bio and the abstract in case you would like to visit us to see
his talk
and meet with him:
Pat Hayes (http://www.ihmc.us/groups/phayes/)
from the Florida Institute for
Human and Machine Cognition (http://www.ihmc.us/research.php)
will
present the 2011 Miller Lecture on 'Semantics of Cartography'
on the
29th of April 4-5pm in 112 Walker building. Pat holds a BA in
mathematics from Cambridge University, UK as well as a Ph.D.
in
Artificial Intelligence from University of Edinburgh, UK. He
was a
professor of Computer Science at the University of Essex, UK,
Philosophy
at the University of Illinois, USA, and the Luce Professor of
Cognitive
Science at the University of Rochester, USA.
Pat is well known for his contributions to the theoretical
foundations
of Artificial Intelligence as well as his work on formal
semantics and
ontologies. He is especially interested in the representation
of space
and time (see, e.g., his work on modeling cyclic change
together with
Hornsby and Egenhofer) . Pat's work on the Situation Calculus
or Naive
Physics have influenced GIScience researchers for many years.
His work
on the foundations of the Semantic Web, the Resource
Description
Framework (RDF), and the Web Ontology Language (OWL) form the
underpinning of most research on geospatial semantics and
geo-ontologies. Besides his achievements in computer science,
Pat has a
strong foundation in cognitive science.
Abstract:
"A Semantics for Cartography: outline of a sketch of a theory.
It is traditional to draw a sharp distinction between symbolic
and
diagrammatic forms of representation, the latter being
presumed to have
a fundamentally different nature. Cartographic maps are often
cited as a
paradigm for diagrams. I have never thought this to be
correct, and
began a project to interpret maps as symbolic notations,
developing a
semantic theory for them. This talk reports on some
preliminary progress
in this project.
The single most successful theory of semantics for symbolic
languages is
Tarski's theory of truth. At its core, this depends upon the
representation having a productive syntax, which means it can
be parsed
recursively into smaller representational structures, and its
meaning
then built up from the meanings of these smaller components.
The primary
challenge for adapting Tarski to give a semantic theory of
maps,
therefore, is how to understand a map as being made up of
smaller
meaningful parts, and how to explain the particularly
cartographic ways
of composing their meanings back together. This seems to
depend upon a
special relationship between the projection function from the
terrain to
the map surface, and the denotation function from map symbols
to the
terrain entities they represent. We will show how this
relationship
implies certain topological assumptions which must underlie
any
cartographic semantic theory."
Best,
Krzysztof
