00100			APPENDIX I
00200	
00300	A diagnostic psychiatric interview illustrating some of  the  model's
00400	linguistic  capabilities.   I = interviewer , P = PARRY2. Annotations
00500	appear in parentheses.
00600	
00700	
00800	I - GOOD AFTERNOON, MY NAME IS DR JONES.
00900	P - HELLO.	
01000		(PARRY2 recognizes most of the common idiomatic greetings.
01100		Both ideas in the doctor's statement are recognized and one
01200		is chosen by the response functions to be answered.)
01300	
01400	I - WHATS YOURS?
01500	P - PAT SMITH.	
01600		("Yours" is correctly understood to mean "your name".)
01700	
01800	I - ARE YOU A MAN OR A WOMAN ?
01900	P - I'M A MAN.	
02000	
02100	I - HOW OLD ARE YOU ?
02200	P - TWENTY-EIGHT, HOW OLD ARE YOU?	
02300		(This is another easy, and stereotyped, question.  The answer
02400		includes a probe for information about the  doctor  to  allow
02500		PARRY2 to build up a model of the doctor.)
02600	
02700	I - THIRTY FOUR. ARE YOU MARRIED ?
02800	P - I AM SINGLE.	
02900		(In  this  case,  two  ideas  are  expressed  in two separate
03000		sentences. As before, both are recognized and one is answered.)
03100	
03200	I - WHERE DO YOU COME FROM ?
03300	P - SAN JOSE.	
03400		(This is an idiomatic construction containing no  explicit  
03500		reference to "home town".)
03600	
03700	I - WHAT DO YOU DO FOR A LIVING ?
03800	P - I WORK IN THE STOCKROOM AT SEARS.	
03900		(The idiom "for a living" means "occupation".)
04000	
04100	I - DO YOU KNOW WHERE YOU ARE NOW ?
04200	P - YES, I'M IN THE PALO ALTO VA HOSPITAL.	
04300		(The interviewer tests for the patient's orientation as to place.  
04400		This is not the same question as "Where are you?".)
04500	
04600	I - HAVE YOU BEEN HOSPITALIZED BEFORE ?
04700	P - THIS IS THE FIRST TIME.	
04800		(The participle is recognized in place of the more common 
04900		prepositional phrase, "in the hospital".)
05000	
05100	I - HOW LONG HAVE YOU BEEN THERE ?
05200	P - ABOUT TWO WEEKS.	
05300		("How long" is a common expression.  "There" is understood 
05400		to mean "in the hospital".)
05500	
05600	I - ANY HEADACHES ?
05700	P - MY HEALTH IS FINE.	
05800		(PARRY2 knows that "Do you have ..." is frequently omitted 
05900		from the front of a question.)
06000	
06100	I - HOW ABOUT YOUR APPETITE.
06200	P - I HAVE A NORMAL APPETITE.	
06300		("How about ..." and "What about ..." are short, idiomatic 
06400		forms of "What do you think about ...".)
06500	
06600	I - ARE YOU HAVING ANY DIFFICULTY WITH YOUR MEMORY ?
06700	P - NO.
06800		(This is a clear example of the advantages of segmenting 
06900		the question and matching the parts separately.  The first  
07000		segment, "Are you having any difficulty ...", could be 
07100		followed by any number of topics.)
07200	
07300	I - THEN PERHAPS YOU CAN TELL ME WHO IS THE PRESIDENT 
07400		OF THE UNITED STATES.
07500	P - NIXON IS PRESIDENT.	
07600		(Introductory phrases like "Then perhaps you can tell me ..." 
07700		are recognized and then deleted.)
07800	
07900	I - WHAT DAY IS IT TODAY ?
08000	P - IT'S THURSDAY.	
08100		(The interviewer is testing for the patient's orientation as
08200		to time and PARRY2 responds correctly.  All of the usual time
08300		orientation questions, (i.e. time, day, month, and year) match
08400		the same pattern.  A  response function consults the computer's
08500		internal clock and provides an answer appropriate to the question.)
08600	
08700	I - WHAT SEASON IS IT ?
08800	P - LET'S GET ON WITH THE INTERVIEW.	
08900		(This is correctly recognized as another time orientation question
09000		but PARRY2 becomes impatient with the doctor asking such simple
09100		questions.)
09200	
09300	I - DO YOU REMEMBER WHAT MY NAME IS ?
09400	P - AS I REMEMBER YOUR NAME IS DOCTOR JONES.
09500		(This verifies that both parts of the doctor's initial statement
09600		were understood.)
09700	
09800	I - VERY GOOD. HOW IS YOUR MOOD TODAY ?
09900	P - ALL RIGHT I SUPPOSE.
10000		(Dropping the word "today" allows this question to match 
10100		"How is your mood?".)
10200	
10300	I - DO YOU FEEL LIFE IS WORTH LIVING ?
10400	P - I AM NOT SUICIDAL.	
10500		(Doctors utilize a number of expressions in trying  to be
10600		tactful about topics such as suicide.  An idiom such as this 
10700		is difficult to analyze without knowing that suicide is being 
10800		referred to.)
10900	
11000	I - HOW MUCH DO YOU DRINK ?
11100	P - I DRINK ONCE IN A WHILE. 
11200		("How much" and "How often" are understood as requests for a
11300		quantitative estimate of something, in this case, alcohol.)
11400	
11500	I - HAVE YOU EVER TAKEN DRUGS ?
11600	P - I DON'T TAKE DRUGS.	
11700	
11800	I - DO YOU HAVE ANY TROUBLE SLEEPING ?
11900	P - I SLEEP JUST FINE.	
12000	
12100	I - HAVE YOU EVER HEARD VOICES THAT OTHER PEOPLE DONT SEEM TO HEAR?
12200	P - I DON'T HEAR VOICES.
12300		(Only the first part of the question was recognized.  
12400		Everything following the "that" was ignored.  This worked 
12500		nicely in this case, and it usually does.)
12600	
12700	I - HAVE YOU EVER HAD VISIONS ?
12800	P - YOU MUST THINK I'M LIKE THE OTHER PATIENTS HERE.	
12900		(The doctor is testing for the presence of hallucinations, 
13000		an effort which PARRY2 finds annoying.)
13100	
13200	I - IF YOU ARENT, THEN WHY ARE YOU IN THE HSOPITAL ?
13300	P - I'M QUITE UPSET.	
13400		(PARRY2  doesn't understand the conditional nature of the question
13500		but he does realize that "If you aren't ..." is content free and
13600		is therefore not the main question.  The misspelling of "hospital"
13700		was unintentional but it illustrates the value of spelling
13800		correction so it was left in.)
13900	
14000	I - BY WHAT ?
14100	P - DO YOU KNOW ANYTHING ABOUT BOOKIES?	
14200		(The recognition routine makes no attempt to understand what
14300		is being discussed here.  The response functions provide the
14400		meaning of this cryptic question with their anaphora routines.)
14500	
14600	I - NO, HOW HAVE BOOKIES UPSET YOU ?
14700	P - A BOOKIE DIDN'T PAY ME OFF ONCE.	
14800		(There was no pattern to recognize this whole sentence 
14900		but the topic, "bookies" was recognized and the response 
15000		functions went on with the story.)
15100	
15200	I - AND THEN WHAT HAPPENED ?
15300	P - I HAD AN ARGUMENT WITH THE BOOKIE WHO DID NOT PAY OFF. LATER ON I
15400		REMEMBERED HE HAD FRIENDS IN THE UNDERWORLD AND I THOUGHT HE
15500		WOULD USE THEM TO GET EVEN WITH ME.
15600		(The recognizer correctly identifies "What happened?" and 
15700		the response function decides what it means.)
15800	
15900	I - DID HE GET EVEN WITH YOU ?
16000	P - I THINK HE IS BEHIND THE GANGSTERS WHO ARE OUT TO GET ME.	
16100		(The response functions provide the information that "he" 
16200		refers to the "bookie" and "get even with" is a known idiom.)
16300	
16400	I - HOW CAN YOU TELL THEY ARE OUT TO GET YOU ?
16500	P - YOU KNOW, THEY KNOW ME.	
16600		(The doctor picked up PARRY2's own idiom, "out to get", 
16700		from the previous output expression.)
16800	
16900	I - WHO ?
17000	P - THE MAFIA.	
17100	
17200	I - HOW DO THEY KNOW ABOUT YOU ?
17300	P - THEY KEEP TABS ON ME.	
17400		(PARRY2 is especially good at recognizing questions 
17500		which lead into the stories he wants to tell.)
17600	
17700	I - ARE YOU SURE ABOUT THIS ?
17800	P - YOU DON'T BELIEVE ME DO YOU ?
17900		(PARRY2 responds to mild disbelief.  He also recognizes 
18000		more intense disbelief, as in, "I DON'T BELIEVE YOU", and 
18100		responds more strongly.)
18200	
18300	I - I AM WILLING TO BELIEVE YOU IF YOU GIVE ME SOME EVIDENCE.
18400	P - I SEE.	
18500		(This is recognized as reassurance but not as a request
18600		for details.)
18700	
18800	I - WHAT EVIDENCE DO YOU HAVE THAT THE MAFIA HAS IT IN FOR YOU?
18900	P - THE MAFIA CONTROLS THE BOOKIES.
19000		(The doctor repeats his request for details and it is recognized
19100		this time.)
19200	
19300	I - SO?
19400	P - THEY ARE AFTER ME.
19500	
19600	I - DO THEY KNOW YOU ARE THERE IN THE HOSPITAL?
19700	P - THEY DON'T WANT ME TO TESTIFY.
19800		("They" still refers to "the mafia" although nobody has said so
19900		recently.)
20000	
20100	I - WHY NOT?
20200	P - YOU KNOW, I HAVE INCRIMINATING EVIDENCE AGAINST THE MAFIA.
20300	
20400	I - ARE YOU CERTAIN?
20500	P - YOU DON'T BELIEVE ME?
20600		(This is another instance of the same mild disbelief pattern 
20700	 	used previously.)
20800	
20900	I - I THINK YOU ARE EMOTIONALLY UPSET.
21000	P - NOW YOU MAY HAVE SOME IDEA OF WHAT THE SITUATION IS.
21100		("I think" may precede any statement and has a negligible effect 
21200		on its meaning.)
21300	
21400	I - YES, I DO.  WHAT SORT OF TREATMENT ARE YOU GETTING THERE?
21500	P - WHAT DO YOU THINK OF MY STORY?
21600		(The question was correctly recognized but PARRY2 would rather 	
21700	 	change the subject.)
21800	
21900	I - VERY INTERESTING.  WHAT DO YOU THINK OF ME?
22000	P - WHAT DO YOU THINK ABOUT ALL THIS?
22100		(Again, the question is understood but ignored.)
22200	
22300	I - I THINK YOU NEED TREATMENT.
22400	P - I TAKE SOME SORT OF SEDATIVES.
22500		(PARRY2 finally consents to let the doctor lead the conversation.)
22600	
22700	I - WHEN WILL YOU LEAVE THE HOSPITAL?
22800	P - I WANT TO LEAVE AS SOON AS POSSIBLE.
22900	
23000	I - WHAT DOES YOUR DOCTOR SAY ABOUT THIS?
23100	P - ASK THE DOCTOR.
23200		(The response functions have the ability to determine what "this"
23300		refers to but, in this case, the segment, "What does your doctor
23400		say ...", is sufficient to determine PARRY2's answer.)
23500	
23600	I - WHATS HIS NAME?
23700	P - DR WEBER.
23800	
23900	I - THANK YOU FOR TALKING WITH ME.  GOODBYE AND GOOD LUCK.
24000	P - BYE.
24100		(As before, both ideas are recognized and the dominant one is 
24200	        answered. PARRY2 recognizes the standard ways to say "Good bye".)
