"Designing End User Information Environments
Built On Semistructured Data Models"
Dennis Quan
MIT
Information overload is becoming an artifact of daily life, negatively
affecting our productive use of e-mail, the Web, and desktop
computers. One fundamental problem is that computers force users to
organize information using rigid tools such as folder hierarchies--the
information age analog of the filing cabinet. Many in the information
retrieval and human-computer interaction communities have begun to
examine this problem in earnest by allowing users to associate
information with objects such as timelines, tasks, and keywords. We
have opted to generalize these approaches by permitting freeform
associations between arbitrary objects, which better matches the
organizational styles of some users while also supporting those who
require a more structured framework for organization. We have
developed an information management tool called Haystack that allows
users to manage information encoded in semantic networks, a
generalized knowledge representation scheme. Haystack takes advantage
of this flexibility to integrate information currently dispersed
amongst multiple separate applications, such as e-mail, contact lists,
calendars, documents, bookmark collections, and notes, and presents a
unified environment that allows users to browse and aggregate items of
importance in whatever way is most natural to them. Haystack also
allows custom information types and modes of presentation to be
incorporated into the system. Furthermore, by raising the level of
expressiveness for recording information, Haystack provides a basis
for users to take advantage of sophisticated approaches to information
retrieval, agent-based negotiation, and collaboration envisioned by
researchers in the Artificial Intelligence, Semantic Web, and CSCW
communities. The talk will begin with a brief demonstration of the
system, after which I will discuss the underlying technologies and
talk about applications to personal information management and
bioinformatics. ( http://haystack.lcs.mit.edu/ )
About the Speaker: Dennis Quan is a research staff member at IBM
Watson Research, where he works on XML and Semantic Web metadata
technologies and applications thereof to bioinformatics. He received
his Ph.D. in Computer Science at MIT based on research into
Haystack. Previously he worked on Sash
( http://sash.alphaworks.ibm.com/ ), creating the Sash integrated
development environment and many of the user interface components of
the system. He also holds S.B. degrees in Mathematics and Chemistry
from MIT.

"Planning descriptive utterances with declarative methods"
Matthew Stone
Rutgers University
Natural language generators take application-specific domain
representations as input, and need to formulate utterances that can
convey this content to human users. To do this, generators must
construct linguistic referring expressions to identify domain objects,
select lexical items to express domain concepts, and use complex
linguistic constructions to concisely convey related domain facts. In
this talk, I argue that such problems are best solved through a
uniform, comprehensive, declarative process. In our approach, the
generator directly explores a search space for utterances described by
a linguistic grammar. At each stage of search, the generator uses a
model of interpretation, which characterizes the potential links
between the utterance and the domain and context, to assess its
progress in conveying domain-specific representations. Specifying
choices in NLG is always a complex, labor-intensive process. In our
approach, choices follow declaratively from syntactic, semantic and
pragmatic characterizations of linguistic forms, and from formal
models of domain context. Our declarative approach has supported the
development of a detailed methodology for designing grammatical and
conceptual resources which the generator can use to achieve desired
output in a specified domain. In many cases, we can create resources
automatically that will allow a generator to reproduce marked-up
sample utterances.

LOGIC SEMINAR
on Tuesday, 23 September 2003, 4:15pm-5:30pm
Math Corner 380:383T
http://www-logic.stanford.edu/seminars.html
The first meeting of logic seminar in AY 2003/2004
At the beginning we discuss organizational questions. The theme for
this quarter and possibly next is decidable theories. We'll begin
with detailed reviews of new papers on decision procedures for
arithmetical formulas with small number of quantifiers (Shih Peng
Tung) as well as decidable fragments of set theory (Harvey Friedman).
There will be occasional special presentations on other topics by
visitors.
First meeting talk:
"Towards a Structural Analysis of Cut-elimination"
Alexander Leitsch
TU-Vienna,Austria
In this talk we show that a large class of cut-elimination methods can
be analyzed by clause terms representing sets of characteristic
clauses (corresponding to LK-derivations). We define (characteristic)
clause terms and illustrate their use in cut-elimination by resolution
(CERES). Moreover we show that the methods of Gentzen and Tait and,
more generally, every method based on a specific set of cut-reduction
rules R, yield resolution proofs which are subsumed by a resolution
proof of the characteristic clause set. As a consequence we obtain
that CERES is never inferior to any method based on R. On the other
hand we show that CERES is not optimal in general; instead there exist
cut-reduction rules which efficiently simplify the set of
characteristic clauses and thus produce much shorter proofs. Further
improvements and pruning methods could thus be obtained by a
structural (syntactic) analysis of the characteristic clause terms.

"Semantic Web for Earth and Environmental Terminology (SWEET)"
Rob Raskin
Jet Propulsion Lab
SWEET is an effort to improve discovery of Earth science data and
information resources. The project consists of a collection of
ontologies and an associated search tool that eliminates the need for
exact keyword matches. The ontologies are stored in a Postgres DBMS
and are converted on demand into OWL XML format. The ontologies
include both orthogonal concepts (physical property, substance, space,
time, etc.) and integrative concepts (e.g. phenomena) which span
multiple ontology spaces. A numerical ontology was built to provide an
underlying base for the space, time, and physical property ontologies.
We also developed a tool that can query external databases (such as
gazetteers) in response to a request, and then incorporate the new
knowledge within the ontologies. SWEET enables a common semantic
framework for defining, classifying, discovering, sharing, and
accessing Earth science knowledge. This semantic framework is being
incorporated into other NASA-led initiatives that benefit from
semantic interoperability, including the: Earth Science Markup
Language (ESML), Earth Science Modeling Framework (ESMF), and Earth
Science Information Partners Federation Interactive Network for
Discovery (ESIP-FIND).
About the Speaker: Rob Raskin is a Senior Technical Staff Member in
the Earth Science Data Systems Section at NASAs Jet Propulsion
Laboratory. He is Principal Investigator of the NASA-funded SWEET
project and is Manager of Data Access Services at JPLs Physical
Oceanography Distributed Active Archive Center (PO.DAAC). He is Chair
of the Information Technology & Interoperability Committee of the
Earth Science Information Partner (ESIP) Federation. Prior to coming
to JPL, he was a Visiting Fellow at the National Center for Geographic
Information & Analysis at UC-Santa Barbara. He holds a Ph.D. in
Atmospheric Science from the University of Michigan.

LINGUISTICS 237D: An Introduction to Computational Word Learning
on Friday, 26 September 2003, 2:15pm - 3:30pm
Ventura 17
http://www-nlp.stanford.edu/nlp/nlpgroup.html
Introduction to computational methods for learning the syntax and
semantics of words and multiword expressions based on evidence from
language resources (such as dictionaries and thesauri) and actual
language usage in text corpora.
The NLP reading group for the fall quarter is going to be run as a
special course / seminar on Computational Word Learning, by Tim and
myself. We hope to introduce some of the most interesting approaches
in recent years, and to discuss current research and ongoing
developments. We will be delighted to consider any suggestions of
material on this topic which you would like to present or would like
us to make sure we cover.
The first meeting will be next Friday (26th) at 2.15pm, though we are
considering moving this to Fridays at 11am for subsequent weeks,
because Friday afternoons have proved troublesome for some of us in
the past. If you can't make it either on Fridays at 11am or 2.15pm,
and would like to be able to attend, please let us know and your vote
will be counted.
The traditional NLP reading group will resume in winter quarter, so
please have your cutting-edge research and favorite papers ready for
then.
