EDITOR'S NOTE
Summer is the slow time for the CSLI Calendar as far as events but it
is an opportunity for me to revise my sources and you, dear readers,
can help me. I have two web pages that I use and that are accessible
to the general public. The less important one is
"Cognitive Sciences at Stanford"
http://www-csli.stanford.edu/cogsciences/
which I use to track which Stanford departments, research centers,
programs, groups, et cetera might be involved in the general area of
cognitive science/symbolic systems. If you are involved in any
Stanford cognitive science/symbolic systems related research group
that is not listed, I would love to add it. Also if you know of any
listed that are now defunct, changed names, and so on, I would also
like to know that (I'm a bit worried about ones with web pages that
haven't been updated in 4 years).
The second and more important page is
CSLI: Local Area Events
http://www-csli.stanford.edu/events/bayarea.shtml
a listing of seminars, colloquia, and other public talks series both
at Stanford and in the local area (e.g., Berkeley) that are possibly
cognitive science/symbolic systems related. I mine this weekly for
stuff to put in the CSLI Calendar. Again if you know of any series
that I've missed or of new ones that will be starting in the future,
please send me email. Also if any of the listed series are now
defunct, please tell me.
Many thanks,

SRI AI SEMINAR SERIES
on Thursday, 17 June 2004, 10:00am - 11:00am
EJ228, SRI International
http://www.ai.sri.com/seminars/
"Semantic Web Information Processing"
Guizhen Yang
University at Buffalo
The vision of the Semantic Web is to define and share machine
processable data on the Web which will enable a variety of automated
tasks ranging from information search to data integration to content
management to Web services. This talk will present our approach to
realizing the Semantic Web vision, by addressing two fundamental
issues: (1) infrastructure for reasoning with semantically enriched
data; (2) creation of semantic content by transforming semistructured
Web documents into structured data. In the first part of the talk, I
will focus on infrastructure for reasoning with semantically enriched
data. I will present my work on the design and implementation of
Flora-2. Flora-2 unifies the well-known F-logic, HiLog, and
Transaction Logic into one coherent rule-based, object-oriented
knowledge representation system. I will discuss the engineering issues
of language and compiler design, system architecture, and query
optimization, as well as the theoretical issues related to the new
semantics and algorithms for nonmonotonic multiple value and code
inheritance. Flora-2 (and its predecessor Flora-1) has been used in a
variety of application domains, ranging from Web agents to information
integration in bioinformatics to ontology management to building CASE
systems. Since its last alpha-release in late 2002, it has had
hundreds of downloads and a small community of devoted users.
Currently the Flora-2 system consists of 18,000 lines of Prolog/C code
and is freely available at http://flora.sourceforge.net/ . In the
second part of the talk, I will deal with creation of semantic content
from Web documents. Specifically, I will describe novel techniques for
data extraction from Web documents that exhibit a high degree of
precision and recall. The theory behind these techniques is based on
the concept of unambiguity in automatic learning of extraction
patterns and the notion of resilience to changes in Web documents. I
will present complexity results and efficient algorithms for learning
unambiguous and resilient extraction patterns, as well as experimental
results to demonstrate the effectiveness of these techniques in
practice. At the end of the talk I will outline ongoing and future
research on the Flora-2 system and mining semantic information from
Web documents.

"Reading the genome:
How we are trying to make sense and make use of our DNA blueprint"
Gerard Manning
Salk Institute Biological Research Center
We each carry about 850 MB of DNA blueprint to our bodies. The program
encoded by this molecule determines every aspect of our body, from
height to looks, even aspects of behavior and personality. The recent
decoding of the human genome has received much acclaim, but as you
might expect from any code that had been patched and revised over a
few billion years - it's not the easiest to understand! This talk will
look at how we are looking at the genome, what it is telling us about
our fundamental biology, and how we can apply it to live longer and
healthier lives. The genome is also ushering a revolution in biology,
moving from a focused hypothesis-driven discipline to one where
complexity and data are emergent. Some of the opportunities and
challenges in this shift will also be presented. No prior knowledge of
bioinformatics, and only a rudimentary grasp of biology will be
assumed.
About the Speaker: Dr. Manning is the incoming director of
bioinformatics for the Salk Institute of San Diego, one of the
nation's premier biological research centers. His research interests
center on the use of computational methods to the understanding and
application of complex biological processes, particularly in genomics
and evolution. He has worked as consultant to academia, and biotech
and pharmaceutical industries, and has held full time positions in
biotechnology, pharmaceutical and bioinformatics software
companies. At the biotechnology company, Sugen, his group carried out
a landmark analysis of the 'kinome' - a subset of the genome
containing 500 genes encoding critical biological regulators called
protein kinases (see http://kinase.com). This work is being used to
develop human therapuetics in over a dozen pharmaceutical companies,
and as a model for other post-genome analyses. At Molecular
Applications Group, he led the team that developed the first
commercial software for analysis of microarray ('Gene Chip') gene
expression data, and pioneered the analysis of multiple bacterial
genome sequences to discover their biological functions. Dr. Manning
has a bachelor of science degree from the National University of
Ireland and a Ph.D. in biochemistry from Stanford University.

"Envisioning the Connected World"
Jerry Fiddler
Founder, Board Member - Wind River
In the not-too-distant future, the majority of electronic devices will
be connected via the Internet or wireless protocols, bringing
convenience and simplicity to daily living, but adding layers of
technology and complexity to devices we use everyday. Jerry Fiddler
will offer a glimpse to his vision of the future: "The Connected
World." He will discuss how this "world system" will evolve through
the convergence of multiple technologies resulting in one, giant
interoperable system. The audience will learn that the road to the
connected world is wide open, and that today marks the beginning of a
new era in the embedded industry.
About the Speaker: Jerry Fiddler is founder and member of the board of
Wind River. Since its establishment in 1981 in a Berkeley garage, Wind
River has grown to become the leading provider of embedded software
worldwide. Fiddler sits on several corporate boards, including
Tensilica, Axis, Crossbow and Nanochip, as well as a number of
advisory and non-profit boards. He has worked actively both with
students and in an advisory capacity at a number of universities,
including University of California, Berkeley, Wharton, and University
of Illinois. He was also a member of the first NRC national study of
networked embedded systems. He received a BA in music and photography,
and an MS in computer science, both from University of Illinois.

"Using the Learning-by-Teaching Paradigm to Design
Intelligent Learning Environments"
Krittaya Leelawong
The idea that teaching others is a powerful way to learn is both
intuitively compelling, and has garnered support in the research
literature. We have developed an architecture for computer-based,
domain-independent Teachable Agents that students teach using an
explicit representational structure, an interactive concept map that
models causal relationships. This structure becomes shared knowledge
between students and the teachable agent. In addition, the concept
map simplifies implementations of tools for monitoring and formative
assessment, the query and quiz mechanism respectively.
The query mechanism lets students ask the teachable agent questions
that are composed from concepts in their maps. Then, the teachable
agent reasons with the concept map to find answers. These mechanisms
allow students to explore qualitative interactions and static
relationships between concepts. When students interact with the
teachable agent via these two tools, they monitor the agent's learning
progress, hence, reflecting on their own knowledge.
Realizing that fifth graders often are novices in teaching and in the
domain of river ecosystems, we have also developed integrated domain
resources and system tutorials as well as the software Mentor Agent.
This agent provides formative assessment through a set of pre-defined,
scaffolded quiz questions to help students assess their knowledge
during the teaching process.
The present study investigates the contributions of three learning
processes in enhancing learning outcomes for fifth-grade
students-external-guided learning (ITS), self-guided learning (LBT),
and self-guided learning with feedback supporting self- regulated
learning (SRL)-in the domain of river ecosystems. The mentor agent
directs the ITS group to learn materials to answer a set of
pre-defined quiz questions, and provides tailored, local feedback on
the structure of students' concept maps. The LBT group teaches the
teachable agent using the same set of tools and receiving the same
feedback as the ITS group, but can choose own learning goals and
directions. The SRL group has access to the same tools as the other
groups but receives feedback that suggests learning strategies of
utilizing tools in the environment. This group also receives global
instead of local domain feedback.
We have measured knowledge gains, the development of learning
strategies, and the ability to transfer. Results from this study
illustrate the importance of different tasks and feedback toward the
design of intelligent learning environments for children learning
complex, scientific domains.

"Automatic Disjunctive Partitioning
for Symbolic Reachability Analysis"
Supratik Chakraborty
IIT Bombay
Reachability analysis is a core problem in verification, analysis and
optimization of digital systems. It is well known that transition
relation partitioning often leads to significant advantages during
reachability analysis. In the context of synchronous sequential
circuits, conjunctive partitioning has been the predominant choice so
far. However, disjunctive partitioning holds a lot of promise, if the
partitioning method can be automated and made efficient. In this
talk, we explore a technique for automatically decomposing a symbolic
transition relation into a disjunction of symbolic transition
relations (additive decomposition). Each transition relation thus
obtained describes a Kripke structure with a unique
successor/predecessor of each state. The special structure of the
decomposed relations allows us to use composition instead of
quantification during reachability analysis. Preliminary experiments
show that automated decomposition plus composition-based reachability
analysis has low overhead when analyzing a large no. of ISCAS89
benchmark circuits.

"Measuring Information Transmission for Team Decision Making"
Timothy W. Rauenbusch
Harvard University
A fundamental problem in designing multiagent systems is to select
algorithms that make correct group decisions effectively. Typically,
each individual in a group has private, relevant information and
making a correct group decision requires that private information be
communicated. When there is limited communication bandwidth or
potential for delays in communication, it is important to select the
algorithm for making group decisions that requires least
communication. In this talk, I will describe the benefits of
quantifying information transmitted by measuring the entropy of
messages to find algorithms for decision making that minimize use of
bandwidth. I will show the results of the analysis of information
content of a diverse group of center-based algorithms, including
several types of auctions, for making group decisions. I will present
a new data structure, the dialogue tree, that compactly represents
complex interactions between individuals and show how it is used to
measure the information transmitted by an algorithm. The talk will
demonstrate that the amount of communication required by an algorithm
is highly dependent on factors of the multiagent system's environment,
such as team size, error tolerance, and the likelihood that a given
agent can perform a particular task. No single algorithm guarantees
the least communication in all environments. A system designer must
consider both coordination and revelation when choosing an algorithm.
I show that systems that implement an unsuitable algorithm for
decision making incur significant costs for wasted communication.
About the Speaker: Timothy Rauenbusch received his Ph.D. in Computer
Science from Harvard University in June 2004. His thesis was entitled
Measuring Information Transmission for Team Decision Making. His
research has focused on the development and analysis of algorithms for
team decision making. He has also worked to develop computer systems
that support negotiation among people. Tim received his undergraduate
degrees in Finance and Computer Science (Summa cum Laude) from the
University of Pennsylvania in 1996. At Penn, he received the General
Alumni Society's Student Award of Merit in part for writing the Quick
Start Manual for Eniac, the world's first general-purpose digital
computer. Before returning to research, Tim worked on Wall Street as
an investment banker. Tim was a visitor at SRI during academic year
2001-2002.
