                    ABSTRACT OF NEXT WEEK'S TINLUNCH

      In the selected paper, Davidson challenges the notion that language
   is founded upon conventions that link together (a) the intentions of
   speakers, (b) the literal meanings of their utterances, (c) the words
   they use.  His central point is that we frequently interpret
   utterances in ways that do not fall under any fixed or known rules,
   whereas a convention must be common knowledge among the parties to it.
   Davidson argues first that no convention can account for the relation
   between an utterance's illocutionary force and the grammatical mood of
   the sentence uttered.  Then he proceeds to argue that the literal
   meaning of words and sentences (as types) is not conventionally tied
   to any standard use that they have.  Finally, he denies that the
   meanings given to words and sentences (as tokens, on particular
   occasions of utterance) is conventionally assigned.  He concludes by
   expressing considerable skepticism as to whether the practice of
   correct interpretation of natural language can be formalized,
   conventionally or otherwise.

                     ABSTRACT OF NEXT WEEK'S SEMINAR
                    ``Emotion:  Theory and Language''

   Emotions are neither feelings, neuro-physiological processes, nor
   cognitions.  Existing views that incorporate any of these claims have
   a flawed presupposition built into them regarding the fundamental
   structure of emotion: they regard emotion as an occurrent property.  I
   argue, by contrast, that a significant class of emotions, including
   love, envy, dread, and anger, are dispositional and relational.
   Emotion terms, or concepts, refer to, or provide a means of
   identifying, complex relations between one individual, who is the
   subject of an emotion, and another individual, event, or object.  This
   picture offers, instead of an occurrence model of emotion, one of
   emotion as a `syndrome'.  Emotions span a number of heterogeneous
   occurrences, dispositions, and variable time periods.  Evidence for
   this position is found in:

	(1) Sentences that involve emotion predication.
	(2) Emotions that cover great time spans.
	(3) The fact that emotions have a number of other types of mental 
            and physiological states as essential componenents.

      Intonational pitch accents (in the sense of Pierrehumbert (l980))
   serve to "mark" constituents of the sentence with respect to their
   role in discourse.  It is argued that the "accenting" of a noun phrase
   may mean one (or more) of the following:
	   (a)  the NP corresponds to a new discourse referent
	   (b)  the NP is a FOCUS of a FOCUS/"Presupposition" structure
   	   (c)  the NP is a TOPIC of a TOPIC/Comment structure 
      An attempt is made to characterize (a - c) as a natural class,
   given an elaborated conception of discourse representation in terms of
   a file (Heim (l982)).

                        SUMMARY OF AREA C MEETING
                  ``The Compilation of Prolog Programs
                 Without the Use of a Prolog Compiler''
                          Ken Kahn, Xerox PARC

      An efficient Prolog interpreter written in Lisp was presented. The
   interpreter was then specialized to run different Prolog predicates.
   These specializations are generated automatically by a partial
   evaluator for Lisp programs called Partial Lisp. It transforms Lisp
   programs to other Lisp programs and knows nothing about Prolog. It was
   argued that the partial evaluation of interpreters can be a substitute
   for compilation. The results of partially evaluating the Prolog
   interpreter for simple Prolog predicates were presented. The speed of
   the specialized interpreters has been found to be about ten times
   faster than ordinary interpretation. These speeds compare favorably
   with an optimizing compiler for the same Prolog dialect and computer
   system. The advantages of using partial evaluation upon an interpreter
   include a much smaller and easily modifiable implementation. The major
   difficulty in generating thousands of small specialized interpreters
   is that it currently takes about two orders of magnitude more time
   than compilation. Different approaches to reducing partial evaluation
   time were presented. The possibilities of specializing the interpreter
   for different uses of the same Prolog predicate were discussed.

                 ``Quantified NP's and Plural Anaphors''
                    Rebecca Root, University of Texas

                       2:00 pm Friday, February 15

      There is a type of anaphora construction, called "E-type" anaphora
   by Evans, in which a quantified noun phrase serves as the antecedent
   of an anaphor which it does not bind.  This is illustrated by the
   following discourse:

      - Every farmer at the meeting raised a question

      - They sounded hostile

      Here the pronoun "they" can be construed to mean either the farmers
   at the meeting or the questions which they raised.  I will be
   discussing this phenomena within the context of discourse
   representation theory, which, because of its non-quantificational
   treatment of singular indefinite descriptions, offers a good framework
   in which to account for the possible meanings of a discourse such as
   this.

                                CSLI TALK
   Talk by Andrew Jones, Institute for Philosophy, University of Oslo
                      10:30, Thursday, February 21
                         Ventura Conference Room

      Jones is the author of a book entitled Communication and Meaning,
   in which, "a new framework is proposed for the description of
   interpersonal communication -- one flexible enough to cover various
   ways in which agents exploit the communication systems they
   use....[the framework is] expressed in a formal language employing
   modal-logical techniques."  He is currently working with others
   (including Dagfinn Follesdal) at the University of Oslo to develop an
   extended course (a one-year full-time program of studies, on the
   introductory level) in communication theory and semantics.  Its four
   basic components will be:

	1) Logic and Computability

	2) Semantics (focusing on Montague semantics and situation semantics)

	3) Communication and intention (including speech act theory and
	additional topics such as human-machine communication)

	4) Information and knowledge (based on Dretske)

   He will describe the program and the intentions behind it and is
   interested in general discussion of teaching programs in this area of
   knowledge.
