TUTORIALS
26 June 1989
 
CONSTRAINED GRAMMATICAL FORMALISMS
Aravind Joshi, University of Pennsylvania
K. Vijay-Shanker, University of Delaware
David Weir, Northwestern University

Our goal is to review a range of constrained grammatical  formalisms  by
considering the following aspects: key features  of  language  structure
the formalisms try to capture,  linguistic  adequacy,  mathematical  and
computational  properties,  parsing  strategies,  kinds  of   structural
descriptions supported, strategies for embedding them in the  unfication
framework, etc. We will  focus  on  those  formalisms  characterized  as
mildly context-sensitive. The presentation will  be  based  on  examples
rather than on formal proofs. Therefore, it will be  appropriate  for  a
wide range of computational linguists, even those whose  investments  in
the construction of a lexicon and a grammar do not allow them the luxury
of playing with alternative formalisms now.

PSYCHOLINGUISTIC APPROACHES TO LANGUAGE COMPREHENSION
Michael Tanenhaus, University of Rochester

I will present a selective review of  recent  psycholinguistic  work  in
three areas: (1) word recognition and lexical access; (2) parsing,  with
a focus on  attachment  ambiguity  and  gap-filling;  and  (3)  anaphora
resolution. In each of  these  areas,  I  will  summarize  some  of  the
influential ideas and the empirical results that have emerged during the
last few years. Basic information will be provided  about  some  of  the
methodological advances that are  enabling  psycholinguists  to  provide
detailed  information  about  immediate   or   "on-line"   comprehension
processes. I will also identify some of the controversial issues  that I
expect will be the focus of psycholinguistic research for the  next  few
years, and I will outline some  areas  where  more  interaction  between
computational linguistics  and  experimental  psycholinguists  would  be
especially fruitful.

MORPHOLOGY AND COMPUTATIONAL MORPHOLOGY
Richard Sproat, AT&T Bell Laboratories

Why study the structure of words computationally why not  just  look  up
words in a dictionary  without  considering  their  internal  structure?
Knowledge of morphology is useful in applications as diverse  as  speech
synthesis,  parsing,  machine  translation,  spelling  correction,   and
Japanese text-editing. The tutorial will outline some major  results  in
theoretical morphology  which  affect  computational  issues,  including
recent linguistic work  on  the  phonological,  syntactic  and  semantic
properties  of  words.  Particular  pieces  of  work  in   computational
morphology will be discussed,  all  of  which  deal  with  theoretically
interesting issues to a greater or lesser extent, and many of which were
done with a particular application in mind. Among the systems  discussed
will be the Decomp module of the MITalk text-to-speech system,  and  the
KIMMO Two-Level morphological analysis system. There will also  be  some
discussion of computational work in areas closely related to morphology,
including the interpretation of  compound  nouns  in  English,  and  the
recognition of word boundaries in inputs where such boundaries  are  not
marked, such as speech or Chinese text. Some of the recent debate on the
computational complexity of morphological analysis will be addressed.

SPEECH TECHNOLOGY
Jared Bernstein and Patti Price, SRI International

This  tutorial  will  review  the  basics  of  speech   production   and
perception, followed by a an overview of  the  major  speech  processing
applications  including  coding-decoding   for   transmission,   speaker
recognition, speech recognition, speech synthesis, and  related  medical
and educational applications. The core of the  tutorial is  an  in-depth
review of speech synthesis and recognition, along with a  discussion  of
metrics for their evaluation and current  directions  of  research.  The
presentation on text-to-speech synthesis will cover current practice and
research issues in letter-to-sound  conversion,  prosodic  construction,
and spectral composition. The presentation of recognition will emphasize
methods for acoustic feature  extraction,  lexical  modeling,  and  word
matching.  The  integration  of  syntactic  and  semantic  knowledge  in
recognition and synthesis will also be covered.

PANEL
26 June 1989

COMPUTATIONAL LINGUISTICS AND RESEARCH IN THE HUMANITIES
Don Walker, Bellcore (Chair); Patrick Hanks, Collins Publishers;
Nancy Ide, Vassar; Mark Liberman, AT&T Bell Laboratories;
Martha Palmer, Unisys; Antonio Zampolli, University of Pisa

Humanists have carried  out  careful  analyses  of  selected  bodies  of
literary texts,  although  usually  not  with  sophisticated  linguistic
tools.   Computational  linguists  have  developed  new  techniques  for
examining linguistic structure, but only recently have  begun  to  study
naturally  occurring  texts  and  to  explore  the  characteristics   of
particular  collections.  A  Text  Encoding  Initiative  has  just  been
established  to  formulate  and  disseminate  international   guidelines
for the encoding and  interchange  of  machine-readable  texts  intended
for literary, linguistic, historical, or other textual research. A  Data
Collection Initiative has also been started to  collect,  annotate,  and
tag a large body of English  texts.  Other  initiatives  in  the  United
States, Europe, and Japan are pursuing similar directions.  The  session
will consider these developments and explore  the  mutual  relevance  of
corpus-based language analysis and  language-based  corpus  analysis  in
this larger context.

Organized with the cooperation of the Association for Computers and  the
Humanities and the Association for Literary and Linguistic Computing.
