EMPIRICAL METHODS IN DISCOURSE INTERPRETATION AND GENERATION
Computational theories of communicative action provide the foundation
for the design of a wide range of AI systems (e.g., intelligent
tutors, believable agents, intelligent software agents (softbots),
etc.) To date, much work in computational theories of discourse has
focused on specifying the mechanisms underlying a particular discourse
phenomenon, however developing the robust, broad coverage, theories of
discourse that are needed in today's systems requires an empirical
basis. Moreover, there are no shared methods, tools or resources for
the discourse community.
This symposium aims to: (1) investigate empirical methods that can be
used in the development and evaluation of computational theories of
discourse, and (2) develop a set of shared resources for the
computational discourse community. Symposium presentations will
address the following issues:
o Corpus-Based methods applied to theories of discourse.
o Evaluation of dialogue modules in implemented systems.
o Simulation tools for developing and evaluating theories of
discourse.
o Coding schemes for the quantitative study of discourse phenomena.
o Tools that support (semi-)automatic or empirical studies of
discourse phenomena.
o Applications and extensions of methods used in traditionally
empirical disciplines (e.g., psychology or sociolinguistics) to
computational theories of discourse.
o Empirical analyses that distinguish between claims made by
different discourse theories.

EXTENDING THEORIES OF ACTION:
FORMAL THEORY AND PRACTICAL APPLICATIONS
Action and its representation continues to play a central role in many
areas of AI. The research focus in these areas has often been
motivated by different issues and types of problems, or based on
different underlying assumptions. Representations vary widely, ranging
from logical specifications to influence diagrams and belief nets to
less complex, but more computationally manageable planning
representations. The assumptions and reasoning methods adopted are
also quite different. Techniques include state- and plan-space
search, regression, logical inference, network algorithms and
analytical methods.
This symposium will bring together researchers with widely different
backgrounds, and provide a forum for discussion of the manner in which
these different approaches to reasoning about action can be brought
together. The two primary goals are: evaluating the state of the art,
especially identifying the issues and assumptions central to different
fields; and identifying relevant research issues for extending
theories of action and putting these theories into practice. The
format will consist of technical presentations, panels and discussion
sessions. Technical presentations will cover recent advances in
extending theories of action, and their application to planning,
diagnosis, and control. The panels and discussion sessions will
evaluate these approaches, and produce recommendations for extending
and unifying various approaches, as well as for closing the gap
between theory and applications.

INFORMATION GATHERING FROM HETEROGENEOUS, DISTRIBUTED ENVIRONMENTS
We are currently witnessing an explosion in the amount of information
that is available from various sources, such as the Internet. Along
with the rise in the number of information sources, there is also a
growing number of systems and protocols for providing user friendly
browsing of this information. Although browsing is an important form
of obtaining information, it is a limited, and often time-consuming
form of interaction. A challenge to Artificial Intelligence
researchers is to develop techniques for providing better access to
the wealth of available information. The purpose of this symposium is
to bring together researchers working on topics relating to
information gathering in heterogeneous and distributed environments.
Specifically, we will discuss the challenges in providing intelligent
and efficient access to this information. Topics that will be
discussed at the symposium include: knowledge representation,
reasoning, planning, learning, and knowledge sharing as they relate to
information gathering. We will also hear about major ongoing projects
in this area.

INTEGRATED PLANNING APPLICATIONS
The planning field has finally begun to take on real, or at least
realistic, applications. Traditionally, a key application for
planning systems has been robotics. Recently, new areas for
application have emerged, including planning for data analysis tasks,
virtual reality environments or other simulated environments, medical
applications, and factory automation. Invariably, once a planning
application becomes realistic, issues arise regarding the integration
of the planning system with its environment, such as what is difficult
or easy about particular applications, what similar applications have
in common, and how technologies can be integrated.
The goal of this symposium is to explore the boundary between planning
systems and their environments. The symposium welcomes interested
participants who have worked on planning applications or have
integrated planning into other systems. We plan to make the symposium
interactive and participatory. Therefore, we encourage potential
participants to send electronic mail to howe@cs.colostate.edu, letting
us know that you plan to attend the symposium and summarizing your
research interests and relevant background.
The symposium will consist primarily of presentations of selected
papers and panels, followed by discussions focussed around issues and
application areas. In addition, at least one senior researcher will
be asked to present an invited talk. We will disseminate accepted
papers and key discussion topics in advance of the symposium.

State University, howe@cs.colostate.edu; Amy Lansky, NASA Ames
Research Center; Robin Murphy, Colorado School of Mines.

INTERACTIVE STORY SYSTEMS: PLOT AND CHARACTER
We will explore conceptual, technical, and artistic issues involved in
integrating plot and character to create "interactive story systems" -
simulated dramatic situations in which human users actively
participate. Symposium participants will include academic and
industrial researchers in artificial intelligence and interactive
media, as well as professionals from the computer games, educational
software, film, and video industries. Symposium sessions will be
organized around different design issues for interactive story
systems. For each session we will have a mix of speakers reporting
related work and facilitators raising questions and issues for
discussion. Anticipated session topics include:
o What is the space of interaction modes for interactive story systems?
o How can a story arise from character-based and other simulation-based
approaches?
o How can semi-autonomous characters be made to follow an intended plot
structure?
o How can plot structures be designed to accommodate user interaction?
o What special properties make characters compelling in a story context?
o What is the role of an automated story master?
o What special issues or design concepts arise in the design of interactive
story systems for children?

LESSONS LEARNED FROM IMPLEMENTED SOFTWARE ARCHITECTURES
FOR PHYSICAL AGENTS
The goal of this workshop is to shed light into reasons for
architectural decisions in building artificial agents. Many important
questions affect architectural decisions. For this workshop, we ask
questions like the following only with respect to architectural
decisions.
How should the agent arbitrate/coordinate/cooperate its behaviors and
actions? How can human expertise be easily brought into an agent's
decisions? How much internal representation of knowledge and skills is
needed? How should the computational capabilities of an agent be
divided, structured, and interconnected? What types of performance
goals and metrics can realistically be used for agents operating in
dynamic, uncertain, and even actively hostile environments? Why should
we build agents that mimic anthropomorphic functionalities? What, if
any, role can advanced simulation technology play in developing and
verifying modules and/or systems? How can a given architecture support
learning?

REPRESENTATION AND ACQUISITION OF LEXICAL KNOWLEDGE:
POLYSEMY, AMBIGUITY, AND GENERATIVITY
The lexicon is at the core of many NL, MT, IR, and KR systems, and
thus can play a central role in determining the success or failure of
a system. Nonetheless, points of sharp controversy have arisen
concerning the most flexible and powerful way to represent the
extensive variety of lexical information required to drive robust
applications. We intend this symposium to provide a forum to discuss
problematic issues of lexical representation, and ways to solve
difficult and complex questions. The symposium will maintain a
balance between theoretical and applications oriented papers.
There will be two ``special events'' at the Workshop: one is an
invited talk by Professor Charles Fillmore on the future of lexical
research, with some visionary thoughts from a pioneer in the field of
lexical semantics. The other is a set of break-out sessions to
involve workshop participants, focusing on ``burning issues'' such as
limits of corpus analysis, machine-readable dictionaries, thematic
roles, linking rules, and other ``limits'' to be set by the
participants. This section of the workshop involves ``pushing the
limits'', and we plan to push our own limits together in focussed
discussions on how to solve such persistent problems.

REPRESENTING MENTAL STATES AND MECHANISMS
The ability to reason about mental states and cognitive mechanisms
facilitates performance at a variety of tasks. The purpose of this
symposium is to enhance our ability to construct programs that employ
commonsense knowledge of mental phenomena in an explicit
representational format that can be shared across domains and systems.
The need to represent knowledge of mental activity transcends usual
disciplinary boundaries to include, not simply conditions whereby an
agent might introspect about the mental world, but most reasoning
tasks where systems interact with users, coordinate behaviors with
autonomous agents, or consider their own beliefs and limitations with
respect to the physical world.
The symposium will consist of individual participant presentations,
interactive invited talks, panel discussions, and one or more
break-out sessions on focused topics. Additional details, including
position papers describing relevant issues, are available through the
World Wide Web via mosaic at URL
ftp://ftp.cc.gatech.edu/pub/ai/symposia/aaai-spring-95/home_page.html
(or via ftp on ftp.cc.gatech.edu in directory
pub/ai/symposia/aaai-spring-95). Because participation is anticipated
to be quite heterogeneous in terms of both academic background and
subfield affiliation, we intend to emphasize interaction and the
exchange of ideas rather than traditional presentations. A participant
will be considered especially successful when answering the question
"What does my representation offer those outside of my own paradigm?"

SYSTEMATIC METHODS OF SCIENTIFIC DISCOVERY
Scientific discovery is among the most celebrated creative processes,
and receives scholarly attention from several disciplines including
AI. Experience has shown that some scientific reasoning can be made
systematic. This symposium will examine the state of systematic
methods for scientific inference, with special emphasis on insights
that promise broad applicability within science. The development of
such methods will, as foreseen by Allen Newell, increasingly lead to
the sciences taking a metaposition, in which doing science will
involve understanding the information processes of scientific
inference, and building systems that do the object-level science,
leading to a convergence of AI and the scientific enterprise.
This symposium will feature: descriptions of existing methods or
systems and their achievements in natural, social, and mathematical
science; generalizations made over these systems; exploratory task
analyses; and psychological/historical studies that promise to lead to
further systematic methods.
