CSLI/MEDIA X INDUSTRIAL AFFILIATES RECRUITMENT DAY
Friday, March 7, 2003, 10:00am-3:00pm
Cordura Hall
(note this is only for Stanford students)
The Industrial Affiliates of the Center for the Study of Language and
Information (CSLI) and Media X carry out research in areas related to
information, computing and cognition (including HCI, speech and
language processing, communication technology and the design and study
of interactive media). Next month CSLI is sponsoring a recruitment
day for Stanford students (undergraduate or graduate) interested in
careers in these areas. Students will be able to meet researchers
from the affiliated companies and discuss permanent employment or
summer internships. Please note that this is not a job fair, it's
more informal, it's an opportunity for the students to talk to
industry representatives in a relaxed environment. Each company will
have a room located in the building of Cordura Hall.
If you are interested, please register by returning the questionnaire
at the end of this message to Michele King (mking@csli.stanford.edu)
by Tuesday, February 18, 2003. The list of registered students will
be made available to industry members prior to the event.
For more information about CSLI and Media X, see
http://www-csli.stanford.edu/ and http://mediax.stanford.edu/
**Important Notice Below**
To receive further announcements about this recruitment day and other
related information, please send email to majordomo@csli.stanford.edu
with "subscribe csli-students" in the body of the message. No need to
do anything if you already did that for last year's CSLI Recruitment
Day. If you wish to take your name off the list, send email to

http://www.adobe.com/products/photoshopalbum/main.html
Adobe has developed Photoshop Album, a next-generation photo
application that enables consumers to organize, fix, share, and
preserve their digital photos. Previous solutions have been too
complex for many consumers to accept, and a radical change in approach
was needed to both simplify the user's experience and deliver more
capability. This talk will describe the new paradigms used in this
program and explore several of the challenging design issues,
especially with regard to achieving consumer ease-of-use.
About the speaker: Michael Slater is a senior manager in Adobe's
Digital Imaging and Video business unit, responsible for technology
strategy. He was formerly the chairman and cofounder of PhotoTablet,

The Application of Psychoacoustics to Speech Enhancement
Brent Edwards
VP of Research, Sound ID, Inc.
The ability to understand speech can be adversely affected by a
variety of causes, such as reverberation, background noise and hearing
impairment. Auditory models and psychoacoustic considerations may
lead to signal processing techniques that improve both speech
intelligibility and quality in these conditions. Results from studies
on the psychoacoustic consequences of noise masking and sensorineural
hearing loss suggest that the same solution could be applied to both
conditions. This talk will detail several aspects of auditory
perception under these two conditions, and a Psychcoacoustic Turing
Test will be described that uses these details to specify a signal
processing solution. Data will be presented on the capability of this
solution to improve speech intelligibility and quality, and the
application of this solution to a telecommunications product will be
shown.
About the speaker: Brent Edwards, Ph.D., Vice President of Research
Brent Edwards completed his Ph.D. in electrical engineering at the
University of Michigan in 1992, where he investigated the application
of signal processing techniques to the human auditory system. He
followed with a postdoctoral fellowship in psychology at the
University of Minnesota, where he conducted research on experimental
human psychoacoustics. From 1995 to 2000 he was director of research
at GN ReSound, responsible for DSP development, hearing science,
signal processing research and clinical audiology. He has published
extensively on hearing and signal processing in academic journals and
industry magazines, and made numerous presentations at scientific
conferences and industry-related seminars.

What are the ingredients of language?
Michael Ramscar
http://www-psych.stanford.edu/~michael/
Can any part of language be studied independently of meaning and
context? I shall discuss a series of experiments that challenge
claims that context independent rules are necessary to explain
language processing. These studies demonstrate that meaning plays a
striking and decisive role even in the most low-level aspects of
grammatical processing: e.g., the past-tense inflection of verbs. For
example, when asked to produce the past tense of "food-drive," people
were more likely to say "food-drove" when food-driving involved
cruising door-to-door to collect food, but were likely to say
"food-drived" when it involved sitting in front of a
supermarket. Indeed, in spite of previous claims to the contrary,
meaning turns out to matter more than grammatical considerations when
it comes to predicting the patterns of past-tense inflection. I
conclude that explanations of language need not necessarily include
explicit, abstract mental rules; however they must include
considerations of meaning and context.

'One is a lonely number':
some recent trends in the logic of communication
Johan van Benthem
Stanford and Amsterdam
http://staff.science.uva.nl/~johan/
Logic is not just about single agents describing fixed situations by
monologues. Every speech act changes information states of interacting
groups of people. This calls for dynamic-epistemic logics keeping
track of such changes, due to Plaza, Gerbrandy, Baltag, van Ditmarsch,
and others, such as Fagin-Halpern-Moses- Vardi, or Parikh. We explain
how update logics work, and what broader issues arise. In particular,
how do statements produce common knowledge (if/when they do), and how
can we plan discourse in public settings without informing everyone
about everything (since ignorance is the basis of civilised social
life)? Such issues have clear analogies with analysis/synthesis of
programs in computer science, and I conclude with new examples of what
Parikh has called 'social software'.

Learning Countability in English and Dutch
Tim Baldwin
CSLI
Noun countability in languages such as English and Dutch has
ramifications for any task requiring linguistic precision. For a
system to make use of it, however, individual nouns must be annotated
according to their countability properties. This is an expensive task,
and complicated by factors such as productive alternations between
countability classes and domain-specific word usages. We present a
basic classification of noun countability for English and Dutch, and
use this to motivate a set of corpus-based features to learn
classifiers for the individual countability classes from. We describe
results for the English classifiers based on the output of a POS
tagger, chunker and full parser, individually and in combination. We
then outline how these results can be applied to the cross-linguistic
task of learning countability in Dutch, and also discuss unsupervised
monolingual methods for learning countability in English and Dutch.

Infixation in Tagalog: cluster markedness
vs.
transition similarity
Kie Zuraw
UCLA
The Tagalog infixes -um- and -in- both vary in position when their
stem begins with a consonant cluster: gr-u.m-ad.wet ~ g-um.-rad.wet
'to graduate'. Given evidence from elsewhere in the language that a
constraint against complex syllable onsets almost always outranks a
constraint against syllable codas, it is puzzling that the variant
gr-um-adwet is possible (and very frequent).
Furthermore, if what makes complex onsets marked is that the first
consonant's perceptibility is impaired by the lack of a following
vowel (as argued by Steriade 1995), then we should expect that the
more sonorous (vowel-like) the second consonant, the less marked the
cluster. That is, gw- is more marked than ga-, but less marked than
gl-. Surprisingly, field data and written frequencies on the Web
indicate that an infix is more likely to break up a less-marked
cluster: e.g., g-in-w... is more frequent that gw-in-..., whereas
gr-in-... is more frequent than g-in-r.... In other words, infix
placement is not being exploited to reduce cluster markedness.
We could speculate that what makes gr-um-adwet possible is its
preservation of the cluster [gr]. Applying this line of reasoning to
the frequency difference noted above, we would conclude that
faithfulness to clusters like [gr] must be more highly valued than
faithfulness to clusters like [gw]. This parallels typological
findings in Fleischhacker (2000) concerning repair by epenthesis of
onset clusters in borrowed words: onsets with a less-sonorous second
member are more likely to repaired by prothesis, which preserves the
cluster intact (sp- -> isp-), and onsets with a more-sonorous second
member are more likely to be repaired by anaptyxis, which splits the
cluster (sw- -> siw-). Fleischhacker attributes this finding to
perceptual comparison between the unrepaired onset and the repaired
onset: because the transition from [s] to [w] is already relatively
vowel-like (there is a sudden appearance of vowel-like formants),
insertion of a vowel creates a relatively small perceptual departure
from the original; the transition from [s] to [p], by contrast, is not
at all vowel-like, and insertion of a vowel would create a large
perceptual departure from the original. Because the Tagalog infixes
begin with a vowel, the reasoning is parallel: g-in-w... is more
similar to gw... than g-in-r... is to gr....
The infixation facts are interesting because (i) they are a further
example of the influence of segment-transition similarities on
phonology, alongside Fleischhacker's cases from epenthesis, partial
reduplication, puns, and alliteration; and (ii) they are further
evidence that, contrary to what the factorial typology seems to
predict, infix placement is not exploited to resolve preexisting
markedness violations in the stem.
A unified analysis of epenthesis and infixation is attempted by
uniting correspondence constraints that relate surface representations
(as opposed to input-output faithfulness) into a single family of *MAP
constraints, where *MAP-S1S2(X,Y) forbids correspondence between X in
string S1 and Y in string S2 (where S1 and S2 can be L2 source word
and adapted loan, or base and reduplicant, or stem and infixed form,
etc.). Crucially for the epenthesis and infixation cases, X and Y can
be annotated for phonetic context: e.g., T^W, 'stop that precedes a
glide'. By default, *MAP(X,Y) outranks *MAP(Z,W) if the perceptual
distance between X and Y is greater than that between Z and
W. Evidence from loan phonology, where adaptations predicted by
established Faith-IO rankings of the language (if the L2 source is
taken as the input) are very often reversed in favor of apparent
perceptual matching, argues that the correspondence constraints
involved in comparison of surface forms are separate from those that
regulate contrasts and alternations.

A New Kind of Science
Stephen Wolfram
Wolfram Research
http://www.stephenwolfram.com/
Stephen Wolfram, the theoretical physicist who has been described by
Wired magazine as "the Bob Dylan of physics" and a "Jedi
mind-warrior," will speak about his book "A New Kind of Science."
Wolfram's paradigm shift may have profound implications for our
understanding of physics, biology, and perhaps even the character of
intelligence in the universe. The London Daily Telegram headline
asked, "Is this man bigger than Newton and Darwin?"
At complexity's core--from marvels as diverse as the shape of a
snowflake to the structure of space and time--Wolfram finds
simplicity. Starting with a handful of computer experiments, Wolfram
has developed a new way to explain the essential mechanisms of the
natural world. His premise is that simple rules (the kind that make up
computer programs or describe how to construct a mosaic tile pattern),
rather than complex mathematical formulas, have far more potential to
accurately describe our complex universe. "The aphorism that the
weather has a mind of its own may be less silly than you might
imagine," Wolfram says.
A New Kind of Science has received a colossal amount of press
coverage. Pre-release orders put the 1200-page book on Amazon's top
few hundred for much of the past six months--occasionally cracking the
top 50--and within a week of its publication, the entire 50,000 print
run had sold out.
About the speaker: Stephen Wolfram was educated at Oxford University
and Cal Tech. He was a fellow at the Institute for Advanced Study at
Princeton, and his early work on elementary particle physics and its
relationship to cosmology was recognized with a MacArthur "Genius"
Award in 1981. Wolfram is also the creator of Mathematica, the
scientific software used by millions of scientists and researchers,
engineers, students and others.
This event is co-sponsored by the Stanford Center for Innovations in
Learning and the Symbolic Systems Program, and is free and open to the
public.

Markedness Hierarchies and Conflation
Paul de Lacy
Cambridge University
This talk presents a theory of markedness hierarchies and their formal
expression in Optimality Theory. Informally, the aim is to show that
it is not accurate to say "a is always more marked than b" (for any
pair of values a and b in a particular markedness hierarchy); instead,
it is only valid to claim that "b is never more marked than a." The
latter formulation allows for situations of 'markedness conflation':
where markedness distinctions are eliminated for particular phenomena
(i.e. where a and b are treated as equally marked).
In formal terms, the aim is to show that hierarchy-referring
constraints refer to contiguous ranges of scale elements, starting
with the most marked element. As an example, the vowel sonority
hierarchy | E i,u e,o a | (E=schwa) is related to stressed positions
by a series of constraints. Instead of employing a fixed ranking
(Prince & Smolensky 1993, Kenstowicz 1996), constraints refer to
ranges of the scale: i.e. *Hd/{E}, *Hd/{E,i,u}, *Hd/{E,i,u,e,o},
*Hd/{E,i,u,e,o,a}. These constraints are shown to allow for stress
systems like Nganasan's, which ignores the sonority distinction
between central vowels [E] and high vowels [i y u] on the one hand,
and medial and low peripheral vowels on the other.
The same point is made for faithfulness constraints. For the major
place of articulation scale | dorsal labial coronal glottal |,
faithfulness constraints are argued to have the form IDENT{dorsal},
IDENT{dorsal, labial}, IDENT{dorsal, labial, coronal} and
IDENT{dorsal, labial, coronal, glottal}. These allow for
'faithfulness conflation' - where deviations from the input form incur
equal faithfulness violations, allowing markedness constraints to
determine the winner. Informally, 'faithfulness conflation' describes
a situation where perfect identity to the input form is prevented, and
the winning form is chosen entirely for markedness reasons. Evidence
will be adduced from consonant coalescence in Pali.

Digital Identity Management:
Emerging Standards and Industry Initiatives
Lena Kannappan
France Telecom R&D, San Francisco
mailto:lena.kannappan@rd.francetelecom.com
Digital identities are scattered across ISPs, mobile operators,
instant messaging systems, online businesses, employers, banks,
brokerage firms, insurance companies, department stores, governmental
organizations...the list seems endless, all with little coordination,
interaction or control. Creating a federated identity infrastructure
is the key to correcting this situation. For the consumer or employee,
federated identity management will mean a far more satisfactory
on-line experience as well as new levels of personalization, security,
and control over their identity information. Single user identity
management and common authentication amongst service providers is an
essential building block for the next generation of the Internet and
integration with an array of access devices. As a result, it needs to
be an open standard for network identity spanning all network devices
resulting in an universally open, distributed authentication and
authorization system available from multiple technology providers and
identities issued by many parties. The talk will address the Latest
and Emerging Standards and important Industry Initiatives around this
topic.
About the speaker: Lena Kannappan is France Telecom's Senior Staff
Research Scientist from the R&D center in San Francisco. He currently
heads the Web Services group, Technology Expert Group within Liberty
Alliance. He is also the Secretary for the Liberty Technology Group.
For the past year and half, Lena has been involved in Digital Identity
Management and XML Services strategy efforts as part of the France
Telecom's core team for various business units of France Telecom
including ISP, Mobile, Wireline, eBusiness and Enterprise addressing
B2C, B2B and B2E needs. Before working for France Telecom, as the
Technology Strategist for one of the leading SSO vendors, he has
worked with number of enterprise vendors to bring the architecture
integration models including the first enterprise SSO integration for
a major CRM vendor. Lena Kannappan holds a masters degree in
Electrical Engineering from Anna University, India in 1990 and he
received his bachelor's degree in Electronics and Instrumentation from
Annamalai University, in 1988.
Food and drink will be provided in a small reception from 5:15-6pm.
There will be an informal gathering of the industry attendees in the

REUTERS FOUNDATION DIGITAL VISION PROGRAM SEMINAR
on Wednesday, 12 February 2003, 3:00pm-4:30pm
email for location mailto:digitalvision@csli.stanford.edu
http://reuters.stanford.edu/seminar_speakers.html
Iqbal Z. Quadir
fellow at the Harvard's Center for Business and Government
and at the Center for Business Innovation at Cap Gemini Ernst & Young.
Iqbal Z. Quadir has taught at the John F. Kennedy School of Government
at Harvard University since 2001, focusing on the impact of
technologies in the politics and economics of developing countries.
His particular research interest is in the democratizing effects of
technologies in developing countries with some of his initial thoughts
published in the Summer/Fall 2002 issue of The Fletcher Forum of World
Affairs.
Quadir spent most of 1990s founding and building GrameenPhone Ltd.,
which has now become Bangladesh's largest telephone company, with
revenues of $150 million in 2002. His childhood exposure to the
conditions in rural Bangladesh combined with his later venture capital
experience in New York led Quadir to recognize that the ensuing
digital revolution could facilitate the introduction of telephony to
100 million people living in rural Bangladesh. In 1994, he formally
launched this effort by convincing angel investors to establish a New
York-based company, Gonofone (meaning "People's Phone") to help him
organize what subsequently became known as GrameenPhone.
Quadir's vision of a large-scale commercial project that could serve
all urban areas and 68,000 villages in Bangladesh led him to organize
a global consortium involving Telenor AS, the primary telephone
company in Norway; an affiliate of micro-credit pioneer Grameen Bank
in Bangladesh; Marubeni Corp. in Japan; Asian Development Bank in the
Philippines; Commonwealth Development Corp. in the United Kingdom; and
International Finance Corp. and Gonofone in the United States. He
attracted these investors by complementing his vision with a practical
distribution scheme whereby small entrepreneurs, backed by loans from
Grameen Bank, could retail telephone services to their surrounding
communities. With the support of these investors, GrameenPhone,
established in late 1996, started building a new cellular network and
providing services to the public soon thereafter. To date, it has
built the largest cellular network in the country with investments
approaching $300 million and a subscriber base of 800,000. Its rural
program is already available in more than 20,000 villages, providing
telephone access to more than 30 million people, while helping to
create micro-entrepreneurs in these villages.
Quadir's work has been recognized by leaders and organizations
worldwide, with invitations to speak at many forums, including the
World Bank, United Nations, World Economic Forum, and Aspen Institute,
as well as colleges and universities. He appeared on CNN and PBS and
was profiled in feature articles in Financial Times and The New York
Times, and in several books. The World Economic Forum, based in
Geneva, Switzerland, selected him as a "Global Leader for Tomorrow."
Quadir is an active board member or adviser to several companies and
organizations involved in international development. In the United
States, he is involved with Gonofone, Cap Gemini Ernst & Young's
Center for Business Innovation, Voxiva, MIT Media Lab Asia, Money
Matters Institute, and EnterpriseWorks Worldwide. Internationally, in
addition to GrameenPhone in Bangladesh, Quadir works with UnoPhone in
Norway (which is extending telephone services to rural Uganda), and
the Evian Group in Lausanne, Switzerland.
Earlier in his career, Quadir served as a vice president of Atrium
Capital Corp., an associate of Security Pacific Merchant Bank, both in
New York, and a consultant to the World Bank in Washington DC. He
received an MBA and an MA from the Wharton School, University of
Pennsylvania, and a BS with honors from Swarthmore College.

A New Kind of Science
Stephen Wolfram
Creator of Mathematica, author of A New Kind of Science,
and CEO of Wolfram Research, Inc.
Starting from a few computer experiments, Stephen Wolfram has spent
more than twenty years developing a new approach to science, described
for the first time in his book A New Kind of Science. Basic to his
approach is the idea of studying not traditional mathematical
equations but instead rules of the kind embodied in the simplest
computer programs. A key discovery is that such rules can lead to
behavior that shows immense complexity and mirrors many features seen
in nature. Wolfram has built on this to tackle a remarkable array of
fundamental problems in science, from the origins of apparent
randomness in physical systems, to the development of complexity in
biology, the ultimate scope and limitations of mathematics, the
possibility of a truly fundamental theory of physics, the interplay
between free will and determinism, and the character of intelligence
in the universe. When Wolfram's book was released on May 14, 2002, it
became an instant bestseller, and is now showing many signs of
initiating a major paradigm shift in science. Wolfram's presentation
will cover some of the key ideas and discoveries in his book,
outlining their implications, and discussing their personal and
historical context. An extended question and answer period will be
included.
About the speaker: Stephen Wolfram was educated at Eton, Oxford, and
Caltech, receiving his Ph.D. in theoretical physics in 1979 at the age
of 20. His early work in physics and computer science was recognized
by a MacArthur award in 1981. In the early 1980s he made a series of
now-classic discoveries about systems known as cellular automata,
leading to numerous applications in physics, mathematics, computer
science, biology, and other fields. In 1986 he founded Wolfram
Research, Inc. and began the creation of Mathematica---now the
world's leading software system for technical computing and symbolic
programming (and tool which made A New Kind of Science possible). Over
the past decade Wolfram has divided his time between leadership of his
company and pursuit of basic science. The results of Wolfram's fifteen
years of work were presented for the first time in his book, A New
Kind of Science (May 2002). An instant bestseller, A New Kind of
Science constituted international science news and quickly emerged as
one of the most-discussed science books in decades.
Because we anticipate a large audience, we will use Gates B1 for the
live presentation and Gates B3 as a video overflow room. Students will
have precedence for seating in the Gates B1 room.
Stephen Wolfram will also be speaking in several other venues. He will
speak on the Stanford campus at 7:30PM on Monday, February 10, in
Dinkelspiel Auditorium. For details see http://scil.stanford.edu. This
is a free public event presented under the auspices of the Stanford
Center for Innovations in Learning. Following the CSL Colloquium
(Wednesday, February 12) he will head to San Francisco to speak in the
Herbst Theater starting at 8PM. See

Memory and Learning in Figure-Ground Perception
Mary A. Peterson
University of Arizona
It has long been thought that figure and ground assignment precedes
access to shape and object memories, and therefore that past
experience cannot affect the determination of what is figure and what
is ground. I will briefly review a series of experiments indicating
that this traditional assumption is incorrect. Instead, memories of
known shapes (objects) are accessed sufficiently early in the course
of perceptual processing to affect figure and ground assignment. I
will present a competitive model that accounts both for these results
and for why grounds are perceived to be shapeless, and I will describe
experiments testing predictions from the model. I will close by asking
how much experience with a novel shape is sufficient for it's memory
to influence figure assignment.

In the Shadow of Ideas
Fadhly Bey, Markus Diebel, Tad Toulis,
Pontus Walhgren, and Rico Zorkendorfer
designRAW
What is the aesthetic nature of an idea? Do ideas have an intrinsic
aesthetic? How can an idea be cultivated while at the same time be
left to its own devices?
designRAW is a seven member design collective composed of product
designers working for Lunar Design, IDEO and Zoe Design among
others. The group employs visual design to communicate ideas about
society and the musings that preoccupy it. To date, the three year old
experiment has tackled consumerism, religion and community as well as
the more prosaic needs of washing machines. Each undertaking
germinates from a central idea and is subsequently developed into an
event or design proposal. Utilizing everyday items and simple set-ups
the collective has mounted numerous installations and events to
explore the communicative power of ideas.
designRAW will present samples of their work and discuss the power and
nature of ideas in the formation of their process.
About the Speakers: design RAW is a collective of industrial design

Collaborative Online Robots
Ken Goldberg
University of California Berkeley
Remote-controlled robots have been around for almost a century, used
primarily by trained experts in space, undersea, and in nuclear
cleanup. A new class of tele-robots is now accessible to the public.
"Online Robots" allow anyone on the Internet to visit a museum, tend a
garden, navigate undersea, float in a blimp, or handle protein
crystals.
In this talk I'll describe several projects, focusing on new results
for online robots collaboratively controlled by many users. The
Tele-Actor is a system that combines a human agent (the "Tele-Actor")
with Internet-based distributed audience control. We developed a
formal model of collaborative control that is robust to disturbances
such as drop-outs, randomness, time-delay, and malicious audience
behavior. This model suggests insight into the empirical success of
audience participation systems such as Cinematrix.
In our newest system, ShareCam, $n$ users share control of a single
robotic pan, tilt, zoom camera. We propose the Intersection over
Maximum (IOM) metric for the degree of satisfaction for each user,
which improves over the nonlinear Intersection Over Union (IOU)
metric. We formulate the ShareCam optimization problem and present
several algorithms. For a set of $m$ zoom levels, the algorithm runs
in $O(n2 m)$ time. The algorithm can be distributed to run in $O(n m)$
time at each client and in $O(n \log n)$ time at the server.
This work is sponsored by the National Science Foundation, Intel
Corporation, Microsoft, and UC Berkeley's Center for Information
Technology Research in the Interest of Society.

Incorporating Biological Knowledge into the
Evaluation of Causal Regulatory Hypotheses
Lonnie Chrisman
ISLE and CSLI
Biological data can be scarce and costly to obtain. Many factors
including high dimensionality, small sample sizes and unobserved
variables typically limit statistical power (the ability to
distinguish real effects from spurious ones), making reliable
inference of causal relations extremely difficult. One approach to
dealing with this problem is to incorporate prior domain knowledge
into data analysis. I introduce a framework for testing whether an
experimental data set contains statistically significant support for a
causal or regulatory relationship in the context of domain background
knowledge. Causal hypothesis testing of this type is typically
considered beyond the scope of classical statistical hypothesis
testing methods. I demonstrate that incorporating domain background
knowledge into data analysis can substantially improve statistical
power, making it possible to detect real causal relationships at a
statistically significant level where the same relationships are
indistinguishable from noise from the data alone.

Developmental Biology and "Innate" Mental Structure
Gary Marcus
2002-2003 Fellow of CASBS, Stanford
[Psychology, New York University]
Recent research in brain development and cognitive development leads
to an apparent paradox. One set of recent experiments suggests that
infants are well-endowed with sophisticated mechanisms for learning
language and analyzing the world; another set of recent experiments
suggests that brain development is extremely flexible. In this talk,
I review various ways of resolving the implicit tension between the
two, and close with a proposal for a novel computational approach to
reconciling nativism with developmental flexibility.

Kant's Philosophy of Mathematics in Perspective
Michael Friedman
Philosophy, Stanford
Kant's approach to the philosophy of mathematics is virtually unique
in the history of philosophy in that he assigns the capacity for a
priori knowledge in this science to the faculty of sensibility rather
than the intellect. (Kant takes the intellect to be the source of a
priori knowledge in pure logic but sensibility to be the source of
pure mathematics.) In this way Kant arrives at the quite unusual idea
of a pure or a priori faculty of sensibility, whose structure is given
by the "pure intuitions" of space and time. I explore the variety of
factors motivating and sustaining Kant's unique conception, including
his views on the relationship between pure mathematics and logic, the
roles of construction and calculation in geometry and arithmetic, and
the relationship between pure mathematics and sense perception
(empirical intuition). In this way we see how pure and applied
mathematics are related, for Kant, including especially a particular
application in mathematical physics.

TaskMaster: Resource management in an email client
Victoria Bellotti, Nicolas Ducheneaut, Mark Howard and Ian Smith
PARC
This talk will focus on the design of a novel prototype, TaskMaster,
that embeds task management resources directly in an email client. The
idea of making email more task-centric came from field investigations
of personal information management in which email emerged as a central
locus for information management online. The adoption of the XP
methodology by our research team allowed fieldwork to directly shape
the design rather than taking its usual place as a basis for
critiquing design. TaskMaster was optimized for testing on real
mission-critical email in a two-week evaluation. Some users continued
to use the tool in preference to Outlook, long after the evaluation
study was ended. Since TaskMaster had only a small fraction of the
features of Outlook, the task management features it embodied were
clearly advantageous enough, for several users, to make up for its
many limitations. In addition our user evaluation has provided us with
a great deal of inspiring feedback about how to improve on our design.
About the Speakers: Victoria Bellotti is a Senior Member of Research
Staff in the Computer Science Lab at PARC. She studies current and
prospective technology users trying to understand their work-practice,
their problems and their requirements for future technology. She also
works on analyzing existing or proposed technology design for utility
and usability and on finding ways to improve designs with
user-centered innovations. Victoria studied psychology, ergonomics and
HCI at London University in the UK. After that she worked at Xerox's
Cambridge Research Lab (EuroPARC) for five years. She came to the USA
in 1994 to work in Apple's Advanced Technology Group for three years
before moving back to Xerox to work at PARC in Palo Alto. Her research
interests include Computer Supported Cooperative Work, Computer
Mediated Communication and Ubiquitous Computing.
Nicolas Ducheneaut is a research associate in the Computer Science
Laboratory at the Palo Alto Research Center (PARC) and a Ph.D.
candidate at the School of Information Management and Systems (SIMS),
University of California, Berkeley; his research interests include
computer-supported cooperative work, computer-mediated communication,
and the social impacts of information technologies in organizations.

Probabilistic Word Vector and Similarity based on Dictionaries
http://www.kecl.ntt.co.jp/icl/mtg/members/satoshi/CICLing2003.pdf
Presented by: Satoshi Suzuki, NTT Communications
We propose a new method for computing the probabilistic vector
expression of words based on dictionaries. This method provides a
well-founded procedure based on stochastic process whose applicability
is clear. The proposed method exploits the relationship between
headwords and their explanatory notes in dictionaries. An explanatory
note is a set of other words, each of which is expanded by its own
explanatory note. This expansion is repeatedly applied, but even
explanatory notes expanded infinitely can be computed under a simple
assumption. The vector expression we obtain is a semantic expansion of
the explanatory notes of words. We explain how to acquire the vector
expression from these expanded explanatory notes. We also demonstrate
a word similarity computation based on a Japanese dictionary and
evaluate it in comparison with a known system based on TFIDF. The
results show the effectiveness and applicability of this probabilistic
vector expression.
