SECOND CONFERENCE ON APPLIED NATURAL LANGUAGE PROCESSING
TUTORIALS
9 February 1988
Joe C. Thompson Conference Center, University of Texas at Austin
Morning 8:30 A.M. - 12:30 P.M.
8:30 12:30 INTRODUCTION TO NATURAL LANGUAGE PROCESSING
James Allen, University of Rochester
ABSTRACT
This tutorial will cover the basic concepts underlying the construction
of natural language processing systems. These include basic parsing
techniques, semantic interpretation and the representation of sentence
meaning, as well as knowledge representation and techniques for
understanding natural language in context. In particular, the topics
to be addressed in detail will include augmented transition networks
(ATNs), augmented context-free grammars, the representation of lexical
meaning, especially looking at case-grammar based representations, and
the interpretation of pronouns and ellipsis. In addition, there will
be an overview of knowledge representation, including semantic
networks, frame-based systems, and logic, and the use of general world
knowledge in language understanding, including scripts and plans.
Given the large range of issues and techniques, an emphasis will be
placed on those aspects relevant to existing practical natural
language systems, such as interfaces to database systems. The
remaining issues will be more quickly surveyed to give the attendee
an idea of what techniques will become important in the next
generation of natural language systems. The lecture notes will
include an extensive bibliography of work in each area.
INTENDED AUDIENCE
This tutorial is aimed at people who are interested in learning the
fundamental techniques and ideas relevant to natural language
processing. It will be useful to managers who want an overview of
the field, to programmers starting research and development in the
natural language area, and to researchers in related disciplines such
as linguistics who want a survey of the computational approaches to
language.
BIOGRAPHICAL SKETCH
Dr. James Allen is an Associate Professor and Chairman of the
Computer Science Department at the University of Rochester. He is
editor of the journal Computational Linguistics and author of the
book Natural Language Understanding, published in 1987. In 1984, he
received a five-year Presidential Young Investigator award for his
research in Artificial Intelligence.
8:30 12:30 MACHINE-READABLE DICTIONARIES: A COMPUTATIONAL LINGUISTICS
PERSPECTIVE
Branimir Boguraev, Cambridge University, and
Beth Levin, Northwestern University
ABSTRACT
The lexical information contained explicitly and implicitly in
machine-readable dictionaries (MRDs) can support a wide range of
activities in computational linguistics, both of theoretical interest
and of practical importance. This tutorial falls into two parts.
The first part will focus on some characteristics of raw lexical data
in electronic sources, which make MRDs particularly relevant to
natural language processing applications. The second part will
discuss how theoretical linguistic research into the lexicon can
enhance the contribution of MRDs to applied computational
linguistics.
The first half will discuss issues concerning the placement of
rich lexical resources on-line; raise questions related to the
suitability, and ultimately the utility, of MRDs for automatic
natural language processing; outline a methodology aimed at
extracting maximally usable subsets of the dictionary with minimal
introduction of errors; and present ways in which specific use can be
made of the lexical data for the construction of practical language
processing systems with substantial coverage.
The second half of the tutorial will review current theoretical
linguistic research on the lexicon, emphasizing proposals concerning
the nature of lexical representation and lexical organization. This
overview will provide the context for an examination of how the
results of this research can be brought to bear on the problem of
extracting syntactic and semantic information encoded in dictionary
entries, but not overtly signaled to the dictionary user.
INTENDED AUDIENCE
This tutorial presupposes some familiarity with work in both
computational and theoretical linguistics. It is aimed at
researchers in natural language processing and theoretical linguists
who want to take advantage of the resources available in MRDs for
both applied and theoretical purposes. The issues of providing
substantial lexical coverage and system transportability are
addressed, thus making this tutorial of particular relevance to those
concerned with the automatic acquisition, on a large scale and in a
flexible format, of phonological, syntactic, and semantic information
for nlp systems.
BIOGRAPHICAL SKETCHES

8:30 12:30 SPOKEN LANGUAGE SYSTEMS: PAST, PRESENT, AND FUTURE
Salim Roucos, BBN Laboratories, Inc.
ABSTRACT:
This tutorial will present the issues in developing spoken language
systems for natural speech communication between a person and a
machine. In particular, the performance of complex tasks using large
vocabularies and unrestricted sentence structures will be examined.
The first Advanced Research Projects Agency (ARPA) Speech Understanding
Research project during the seventies will be reviewed, and then the
current state-of-the-art in continuous speech recognition and natural
language processing will be described. Finally, the types of spoken
language systems' capabilities expected to be developed during the next
two to three years will be presented.
The technical issues that will be covered include acoustic-phonetic
modeling, syntax, semantics, plan recognition and discourse, and the
issues for integrating these knowledge sources for speech understanding.
In addition, computational requirements for real-time understanding,
and performance evaluation methodology will be described. Some of the
human factors of speech understanding in the context of performing
interactive tasks using an integrated interface will also be
discussed.
INTENDED AUDIENCE:
This tutorial is aimed at technical managers, product developers, and
technical staff interested in learning about spoken language systems
and their potential applications. No expertise in either speech or
natural language will be assumed in introducing the technical details
in the tutorial.
BIOGRAPHICAL SKETCH:
Dr. Salim Roucos has worked for seven years at BBN Laboratories in
speech processing such as continuous speech recognition, speaker
recognition, and speech compression. More recently, he has been the
principal investigator on integrating speech recognition and natural
language understanding for developing a spoken language system. His
areas of interest are statistical pattern recognition and language
modeling. Dr. Roucos is chairman of the Digital Signal Processing
committee of the IEEE ASSP society.
Afternoon 1:30 P.M. - 5:30 P.M.
1:30 5:30 THE TECHNOLOGY OF NATURAL LANGUAGE INTERFACES
Carole D. Hafner, Northeastern University
ABSTRACT
This tutorial will describe the development of natural language
processing from a research topic into a commercial technology. This
will include a description of some key research projects of the 1970's
and early 1980's which developed methods for building natural language
query interfaces, initially restricted to just one database, and later
made "transportable" to many different applications. The further
development of this technology into commercial software products will
be discussed and illustrated by a survey of several current products,
including both micro-computer NL systems and those offered on
higher-performance machines. The qualities a user should look for in a
NL interface will be considered, both in terms of linguistic
capabilities and general ease of use. Finally, some of the remaining
"hard problems" that current technology has not yet solved in a
satisfactory way will be discussed.
INTENDED AUDIENCE
This tutorial is aimed at people who are not well acquainted with
natural language interfaces and who would like to learn about 1) the
capabilities of current systems, and 2) the technology that underlies
these capabilities.
BIOGRAPHICAL SKETCH
Dr. Carole D. Hafner is Associate Professor of Computer Science at
Northeastern University. After receiving her Ph.D. in Computer and
Communication Sciences from the University of Michigan, she spent
several years as a Staff Scientist at General Motors Research
Laboratories working on the development of a natural language
interface to databases.
1:30 5:30 THE ROLE OF LOGIC IN REPRESENTING MEANING AND KNOWLEDGE
Robert C. Moore, SRI International
ABSTRACT
This tutorial will survey the use of logic to represent the meaning
of utterances and the extra-linguistic knowledge needed to produce
and interpret utterances in natural-language processing systems.
Problems to be discussed in meaning representation include
quantification, propositional attitudes, comparatives, mass terms and
plurals, tense and aspect, and event sentences and adverbials.
Logic-based methods (unification) for systematic specification of the
correspondence between syntax and semantics in natural language
processing systems will also be touched on. In the discussion of the
representation of extra-linguistic knowledge, special attention will
be devoted to the role played by knowledge of speakers' and hearers'
mental states (particularly their knowledge and beliefs) in the
generation and interpretation of utterances and logical formalisms
for representing and reasoning about knowledge of those states.
INTENDED AUDIENCE
This tutorial is aimed at implementors of natural-language processing
systems and others interested in logical approaches to the problems
of meaning representation and knowledge representation in such
systems.
BIOGRAPHICAL SKETCH
Dr. Robert C. Moore is a staff scientist in the Artificial
Intelligence Center of SRI International. Since joining SRI in 1977,
Dr. Moore has carried out research on natural-language processing,
knowledge representation, automatic deduction, and nonmonotonic
reasoning. In 1986-87 he was the first director of SRI's Computer
Science Research Centre in Cambridge, England. Dr. Moore received
his PhD from MIT in 1979.
1:30 5:30 MACHINE TRANSLATION
Sergei Nirenburg, Carnegie Mellon University
ABSTRACT
The central problems faced by a Machine Translation (MT) research
project are 1) the design and implementation of automatic natural
language analyzers and generators that manipulate morphological,
syntactic, semantic and pragmatic knowledge; and 2) the design,
acquisition and maintenance of dictionaries and grammars. Since a
short-term goal (or even medium term goal) of building a system that
performs fully automated machine translation of unconstrained text is
not feasible, an MT project must carefully constrain its objectives.
This tutorial will describe the knowledge and processing requirements
for an MT system. It will present and analyze the set of design
choices for MT projects including distinguishing features such as
long-term/short-term, academic/commercial, fully/partially automated,
direct/transfer/interlingua, pre-/post-/interactive editing. The
knowledge acquisition needs of an MT system, with an emphasis on
interactive knowledge acquisition tools that facilitate the task of
compiling the various dictionaries for an MT system will be
discussed. In addition, expectations, possibilities and prospects
for immediate application of machine translation technology will be
considered. Finally, a brief survey of MT research and development
work around the world will be presented.
INTENDED AUDIENCE
This tutorial is aimed at at a general audience that could include
both students looking for an application area and testbed for their
ideas in natural language processing and people contemplating
starting an MT or machine-aided translation project.
BIOGRAPHICAL SKETCH
Dr. Sergei Nirenburg, Research Scientist at the Center for Machine
Translation at Carnegie-Mellon University, holds an M.Sc. in
