RFC:      420            DRAFT ---- DRAFT
NIC:      12764



TO:       ARPA NETWORK SITES

FROM:     HAL MURRAY,    COMPUTER CORPORATION OF AMERICA

SUBJECT:  CCA ICCC WEATHER DEMO

DATE:     20-DEC-72

---------------------------------------------------------------------




        THE WEATHER DEMO ORIGINALLY DEVELOPED FOR THE ICCC SHOW IS NOW
GENERALLY  AVAILABLE.   IT IS A VERY NICE NETWORK DEMO SINCE IT REALLY
CAN/DOES RUN ON TWO MACHINES.

        THIS DEMO IS TWO INDEPENDENT PROGRAMS.  TOGETHER THEY  TRY  TO
ANSWER ENGLISH QUESTIONS ABOUT THE WEATHER.  FOR EXAMPLE, 'DID IT RAIN
IN BOSTON ON OCTOBER 7?'.  THE NATURAL LANGUAGE PROGRAM IS WRITTEN  IN
LISP.   IT  IS A MODIFICATION OF A SYSTEM DEVELOPED BY T.  WINORGAD AT
MIT.  THE OTHER HALF IS A PRIMITIVE DATACOMPUTER.  THE DATACOMPUTER IS
BEING  BUILT  TO  ALLOW NETWORK USERS TO ACCESS THE UNICON, A TRILLION
BIT STORAGE DEVICE WHICH IS BEING INSTALLED AT AMES.

        WE WILL TRY TO RUN THE DATACOMPUTER DURING NON-PRIME TIME.  IT
CAN  BE THOUGHT OF AS THE SERVER HALF OF THIS COMBINATION.  PRIME TIME
HERE IS 1 TO 5 PM EASTERN TIME, BUT THE MORNING  IS  FREQUENTLY  QUITE
BUSY  TOO.   PLEASE  DO NOT USE THE DATACOMPUTER DURING THIS TIME.  IT
WILL SAVE US THE EFFORT OF TURNING IT OFF.  CURRENTLY, ONLY  ONE  USER
AT A TIME CAN RUN - A LIMITATION OF THE DATACOMPUTER THAT WILL GO AWAY
SOMEDAY.

        IF YOU WANT TO RUN A DEMO  (NOT  JUST  PLAY  AROUND)  WE  WILL
PROBABLY  BE ABLE TO COOPERATE.  PLEASE CALL TO MAKE ARRANGEMENTS WELL
IN ADVANCE.  WE STRONGLY RECOMMEND THAT YOU DO  NOT  TRY  TO  GIVE  AN
IMPORTANT  DEMO UNLESS YOU HAVE USED BOTH VERSIONS OF THE SYSTEMS THAT
WILL BE USED FOR THE DEMO.  EVEN WE GET IN TROUBLE WHEN WE  FORGET  TO
REHEARSE THINGS A BIT.

        WEDNESDAY MORNING IS SCHEDULED PM TIME.  OUR MACHINE WILL  NOT
BE  UP  THEN.   OUR  MACHINE  WILL  NOT BE UP BETWEEN 9 AND 12, BUT IT
FREQUENTLY IS DOWN PAST NOON.

        FOR THE LATEST INFORMATION, LOOK AT  *.TXT  IN  <WDB-DEMO>  AT
CCA.   IN  PARTICULAR,  MESSAGE.TXT  SHOULD  BE A QUICK SUMMARY OF ANY
OTHER INTERESTING TXT FILES.  THE LATEST  VERSION  OF  THIS  FILE  (IN
RUNOFF FORMAT) IS <HGM-MEMOS>ANNOUNCE.RNO.

        THE LATEST VERSION OF THE LISP HALF WILL BE IN  <WDB-DEMO>  AS
WEATHER.SAV.  IT IS A REAL MACHINE USER - BOTH CPU AND CORE.  WE WOULD
OBVIOUSLY PREFER THAT YOU RUN THE LISP HALF ON YOUR  MACHINE.   NORMAL
FTP  CAN  BE  USED  TO  COPY IT - IT IS 400+ PAGES.  IT TAKES 6 MIN TO
TRANSFER IT TO OURSELVES (1.5 MIN OF CPU, 22KBAUD) WHEN THE MACHINE IS
VERY  LIGHTLY  LOADED.   BE  SURE  TO SET THE BYTE SIZE TO 36 ('TENEX'
COMMAND TO FTP) SINCE THIS IS A SAVE FILE.  IF  WE  ARE  REALLY  EMPTY
(WHICH  FREQUENTLY  HAPPENS AT 3 AM) FEEL FREE TO RUN THE LISP HALF ON
OUR MACHINE.





        IF YOU FIND ANY PROBLEMS WITH THE LISP HALF, PLEASE USE SNDMSG
TO  SEND  THINGS  TO  JEFF HILL - HE IS JMH@CCA.  WE ARE INTERESTED IN
EXAMPLES WHICH LOOK LIKE THEY SHOULD WORK BUT DON'T.  IF YOU HAVE  ANY
COMMENTS  ABOUT GENERAL OPERATIONS GLITCHES - LIKE THE DATACOMPUTER IS
NOT UP - BITCH TO ME - HGM@CCA.  CCA IS HOST 31 DECIMAL, 37 OCTAL.

RESTRICTIONS - HINTS
--------------------

        CURRENTLY, WEATHER REQUIRES 'CCA' TO BE  IN  THE  HOST  TABLE.
THE  PATCH  IS  EASY,  BUT I HAVE LOST IT JUST NOW, LET ME KNOW IF YOU
NEED IT.

        WHEN IT ASKS YOU FOR THE DATE, 300 IS THE BEST  ANSWER.   THAT
MAKES  'TODAY'  BE  OCT 26, THE LAST DAY OF THE ICCC DEMO, AND ONE DAY
PAST THE LATEST DATA.  IF YOU TYPE SOME OTHER NUMBER, 'YESTERDAY', AND
'LAST WEEK' WON'T WORK AS WELL.

        'IT' IS NOT WORKING TOO  WELL  THESE  DAYS.   IF  YOU  GET  IN
TROUBLE,  TRY SOMETHING WITHOUT 'IT' THAT IS KNOWN TO WORK.  'WHAT WAS
THE TEMPERATURE IN BOSTON YESTERDAY?' IS BETTER THAN  MOST  -  WE  ARE
QUITE APT TO TEST IT.

        THE SYSTEM DOES NOT KNOW ABOUT THE WORD 'SNOW'.  THERE IS  NOW
WAY TO LIST IT'S VOCABULARY.



DATA
----

        THE DATA FROM OCT 1 THRU 16 IS ALMOST COMPLETE.   BETWEEN  OCT
17  TO  25  IT  IS  FREQUENTLY  SKETCHY.  WE PLAN TO RELOAD EVERYTHING
SOMETIME USING SEPTEMBER'S DATA, SO WE WILL HAVE A COMPLETE  MONTH  OF
CLEAN  DATA.   NOTE: THIS DATA HAS BEEN EXTENSIVELY SUMMARIZED - IT IS
PROBABLY NOT USEFUL FOR PEOPLE INTERESTED IN WEATHER.

        THE OCTOBER DATA IS ABOUT 2400 PAGES OF REAL DATA, PLUS  ABOUT
200  MORE  FOR  THE INVERSION.  THERE ARE ABOUT 4000 CITIES.  THE CITY
NAMES HAVE BEEN CHANGED TO THE LOCAL  CITY  WHENEVER  POSSIBLE.   I.E.
'BOSTON' IS 'BOSTON' NOT 'LOGAN'.

        THIS IS A QUICK ATEMPT TO FIND PEOPLE INTERESTED IN THE WEATHER
DEMO. CAN ANYBODY TELL ME HOW TO SEND MESSAGES TO CROCKER AND/OR DOLAN?

        WE ARE GOING TO TRY TO HAVE THE DATACOMPUTER NEEDED BY THE DEMO
UP NORMALLY. PLEASE DO NOT USE IT WHEN WE ARE BUSY.

        FOR MORE INFORMATION, LOOK IN *.TXT IN <WDB-DEMO> AT CCA.
