TITLE:         Building Large Knowledge Bases: A Critique of
               Lenat's CYC Project

WHO:           Tim Menzies
               AI Lab, UNSW

WHEN:          1-2pm, Friday, 25 Sept, 1992.

ABSTRACT:      Attempts  to  understand  the  strengths  and
               flaws  of Lenat's CYC project (in which it is
               planned to  encode  to  background  knowledge
               required  to  understand  1000  one paragraph
               entries from an encyclopedia) are limited  by
               a  lack  of  technical  publications by Lenat
               regarding  CYC.  Unlike  other  KR  theorists
               (e.g.  Brachman  &  Levesque), Lenat does not
               publish  detailed  formal  reviews   of   his
               representation.  Given  this lack of informa-
               tion, alternative approach is to  review  the
               major strands of non-Lenat KR theory and pose
               the question "how  much  of  contemporary  KR
               theory is used/ addressed by CYC".

               This seminar will review the KR strands known
               to  the speaker:  knowledge fragments, OO-KR,
               task-analysis, Clancey-style blackboards, and
               knowledge-in-context.  Some  of this work has
               been  spectacularly  successful  in  building
               large  knowledge  bases  (though  none on the
               scale of CYC).  We  will  conclude  that  CYC
               seems   to  ignore  much  of  the  useful  KR
               research performed since the inception of the
               CYC project.

WHERE:         Rm 212, Samuel Building,  University  of  New
               South Wales. Enter off Botany Street, stop at
               gate and  ask  grey  men  for  day  pass  and
               instructions.  Park  in  the main car park on
               your left.  The Samuels building is the  gray
               building   directly  behind  the  gates  with
               strange shield-like objects over the windows.
