  Cyc 
 
    A  large  {knowledge-based  system}. 
 
  Cyc  is  a  very  large  multi-contextual  {knowledge  base}  and 
  {inference  engine},  the  development  of  which  started  at  the 
  {Microelectronics  and  Computer  Technology  Corporation}  (MCC) 
  in  Austin,  Texas  during  the  early  1980s. 
 
  Over  the  past  eleven  years  the  members  of  the  Cyc  team,  lead 
  by  {Doug  Lenat},  have  added  to  the  knowledge  base  a  huge 
  amount  of  fundamental  human  knowledge:  {facts},  rules  of 
  thumb,  and  {heuristics}  for  reasoning  about  the  objects  and 
  events  of  modern  everyday  life. 
 
  Cyc  is  an  attempt  to  do  symbolic  {AI}  on  a  massive  scale.  It 
  is  not  based  on  numerical  methods  such  as  statistical 
  probabilities,  nor  is  it  based  on  {neural  networks}  or  {fuzzy 
  logic}.  All  of  the  knowledge  in  Cyc  is  represented 
  {declaratively}  in  the  form  of  logical  {assertions}.  Cyc 
  presently  contains  approximately  400,000  significant 
  assertions,  which  include  simple  statements  of  fact  rules 
  about  what  conclusions  to  draw  if  certain  statements  of  fact 
  are  satisfied,  and  rules  about  how  to  reason  with  certain 
  types  of  facts  and  rules  The  {inference  engine}  derives  new 
  conclusions  using  {deductive  reasoning}. 
 
  To  date,  Cyc  has  made  possible  ground-breaking  pilot 
  applications  in  the  areas  of  {heterogeneous}  database  browsing 
  and  integration,  {captioned  image  retrieval},  and  {natural 
  language  processing}. 
 
  In  January  of  1995,  a  new  independent  company  named  Cycorp  was 
  created  to  continue  the  Cyc  project.  Cycorp  is  still  in 
  Austin,  Texas.  The  president  of  Cycorp  is  {Doug  Lenat}. 
 
  The  development  of  Cyc  has  been  supported  by  several 
  organisations,  including  {Apple},  {Bellcore},  {DEC},  {DoD}, 
  {Interval},  {Kodak},  and  {Microsoft}.
