Subject: Seminar - Inferring Domain Plans in Question Answering (SRI)
INFERRING DOMAIN PLANS IN QUESTION-ANSWERING
Martha E. Pollack (POLLACK@SRI-AI)
AI Center, SRI International
11:00 AM, MONDAY, February 24
SRI International, Building E, Room EJ228 (new conference room)
The importance of plan inference (PI) in models of conversation has been
widely noted in the computational-linguistics literature, and its
incorporation into question-answering systems has enabled a range of
cooperative behaviors. The PI process in each of these systems, however, has
assumed that the questioner (Q) whose plan is being inferred and the
respondent (R) who is drawing the inference have identical beliefs about the
actions in the domain. In this talk I will argue that this assumption is too
strong, and often results in failure not only of the PI process, but also of
the communicative process that PI is meant to support. In particular, it
precludes the principled generation of appropriate responses to queries that
arise from invalid plans. I will present a model of PI in conversation that
distinguishes between the beliefs of the questioner and the beliefs of the
respondent. This will rest on an account of plans as mental phenomena:
"having a plan" will be analyzed as having a particular configuration of
beliefs and intentions. Judgements that a plan is invalid will be associated
with particular discrepancies between the beliefs that R ascribes to Q, when
R believes Q has some particular plan, and the beliefs R herself holds.
An account of different types of plan invalidities will be given, and shown
to provide an explanation for certain regularities that are observable in
cooperative responses to questions.

Subject: Course - Connectionist Summer Workshop Reminder (CMU)
Connectionist Summer Workshop Reminder
This is a reminder that the deadline for applying to attend the connectionist
summer workshop to be held June 20-29 at Carnegie Mellon is March 1st.
Applications are welcomed from graduate students and recent Ph.D.'s and
M.D.'s who are actively involved in connectionist research.
---> This is not just a summer school for training new
connectionists, as a previous announcement may have
implied. We plan to organize small working groups and hold
lively discussions with visiting speakers. New research
will be presented and people are encouraged to bring their
software for demos; we'll supply the machines.
To apply, send a copy of your vita and one relevant paper, technical
report, or research proposal to: Dr. David Touretzky, Computer Science
Department, Carnegie Mellon University, Pittsburgh, PA 15213.

IA: Introduction to Artificial Intelligence
Instructor: Dr. Elaine Rich, MCC, Austin, Texas
Dr. Rich is currently leading a natural language research team at
MCC. She is the author of the widely-read book, Artificial
Intelligence, as well as numerous technical papers.
Course Description: This tutorial will provide an introduction to the
important concepts and techniques of Artificial Intelligence (AI).
The major topics are: What is an AI technique?; Problem solving as
heuristic search; Heuristic search techniques such as hill climbing,
best first search, problem decomposition, constraint satisfaction;
Knowledge representation and inference including logic-based methods,
default reasoning, slot and filler methods and production rules.
IB: Database Management
Instructor: Professor Michael Stonebraker, UC - Berkeley, California
Dr. Stonebraker is a full professor of Computer Science at the
University of California, Berkeley. He is the original implementor of
the INGRES system and is a co-founder of Relational Technology, Inc.
which markets INGRES to engineering and business users.
Course Description: This tutorial will provide an overview of
Database Management. The major topics are: Traditional data models
and query languages including network, hierarchical, and relational
models; Database services such as transaction management, query
optimization, protection, views, integrity control; New approaches to
data models including semantic data models, logic programming, CAD/CAM
data models; Themes of Expert Database Systems such as extended views,

Course Description: This is an introductory tutorial for those who
intend to develop or manage the development of new expert systems, as
well as those who want to evaluate the potential for using expert
systems in their own work. No previous background is assumed. The
topics include: Expert systems features including expert-level
performance, symbolic and heuristic information, and the separation of
Knowledge from Inference; Application areas for expert systems;
Programming techniques used for expert system development including
rules, frames, logic programming; and the use of incremental
prototypes for expert systems development.
