00100			APPENDIX I
00200	
00300	A diagnostic psychiatric interview illustrating some of  the  model's
00400	linguistic  capabilities.   I = interviewer , P = Parry.  Annotations
00500	appear in parentheses.
00600	
00700	
00800	I - GOOD AFTERNOON, MY NAME IS DR JONES.
00900	P - HELLO.	
01000	
01100		(PARRY2 recognizes most of the common idiomatic greetings.
01200		Both ideas in the doctor's statement are recognized and one
01300		is chosen by the response functions to be answered.
01400	
01500	I - WHATS YOURS ?
01600	P - PAT SMITH.	
01700	
01800		("Yours" is correctly understood to mean "your name".)
01900	
02000	I - ARE YOU A MAN OR A WOMAN ?
02100	P - I'M A MAN.	
02200	
02300	I -HOW OLD ARE YOU ?
02400	P -TWENTY-EIGHT, HOW OLD ARE YOU?	
02500	
02600		(This is another easy, and stereotyped, question.  The answer
02700		includes a probe for information about the  doctor  to  allow
02800		PARRY2 to build up a model of the doctor.)
02900	
03000	I - THIRTY FOUR. ARE YOU MARRIED ?
03100	P- I AM SINGLE.	
03200	
03300		(In  this  case,  two  ideas  are  expressed  in two separate
03400		sentences. As before, both are recognized and one is answered.)
03500	
03600	I - WHERE DO YOU COME FROM ?
03700	P - SAN JOSE.	
03800		(This is an idiomatic construction containing no  explicit  
03900		reference to "home town".)
04000	
04100	I - WHAT DO YOU DO FOR A LIVING ?
04200	P - I WORK IN THE STOCKROOM AT SEARS.	
04300		(The idiom "for a living" means "occupation".)
04400	
04500	I - DO YOU KNOW WHERE YOU ARE NOW ?
04600	P - YES, I'M IN THE PALO ALTO VA HOSPITAL.	
04700		(The interviewer tests for the patient's orientation as to place.  
04800		This is not the same question as "Where are you?".)
04900	
05000	I - HAVE YOU BEEN HOSPITALIZED BEFORE ?
05100	P - THIS IS THE FIRST TIME.	
05200		(The participle is recognized in place of the more common 
05300		prepositional phrase, "in the hospital".)
05400	
05500	I - HOW LONG HAVE YOU BEEN THERE ?
05600	P - ABOUT TWO WEEKS.	
05700		("How long" is a common expression.  "There" is understood 
05800		to mean "in the hospital".)
05900	
06000	I - ANY HEADACHES ?
06100	P - MY HEALTH IS FINE.	
06200		(PARRY2 knows that "Do you have ..." is frequently omitted 
06300		from the front of a question.)
06400	
06500	I - HOW ABOUT YOUR APPETITE.
06600	P - I HAVE A NORMAL APPETITE.	
06700		("How about ..." and "What about ..." are short, idiomatic 
06800		forms of "What do you think about ...".)
06900	
07000	I - ARE YOU HAVING ANY DIFFICULTY WITH YOUR MEMORY ?
07100	P - NO.
07200		(This is a clear example of the advantages of segmenting 
07300		the question and matching the parts separately.  The first  
07400		segment, "Are you having any difficulty ...", could be 
07500		followed by any number of topics.)
07600	
07700	I - THEN PERHAPS YOU CAN TELL ME WHO IS THE PRESIDENT 
07800		OF THE UNITED STATES.
07900	P - NIXON IS PRESIDENT.	
08000		(Introductory phrases like "Then perhaps you can tell me ..." 
08100		are recognized and then deleted.)
08200	
08300	I - WHAT DAY IS IT TODAY ?
08400	P - IT'S THURSDAY.	
08500		(The interviewer is testing for the patient's orientation 
08600		as to time and PARRY2 responds correctly.
08700		All of the usual time orientation questions,
08800		(i.e. time, day, month, and year)
08900		match the same pattern.  A  response function consults the
09000		computer's internal clock and provides an answer 
09100		appropriate to the question.)
09200	
09300	I - WHAT SEASON IS IT ?
09400	P - LET'S GET ON WITH THE INTERVIEW.	
09500		(This is correctly recognized as another time orientation 
09600		but PARRY2 becomes impatient with the doctor asking such 
09700		simple questions.)
09800	
09900	I - DO YOU REMEMBER WHAT MY NAME IS ?
10000	P - AS I REMEMBER YOUR NAME IS DOCTOR JONES.
10100		(This verifies that both parts of the doctor's initial 
10200		statement were understood.)
10300	
10400	I - VERY GOOD. HOW IS YOUR MOOD TODAY ?
10500	P - ALL RIGHT I SUPPOSE.
10600		(Dropping the word "today" allows this question to match 
10700		"How is your mood?".
10800	
10900	I - DO YOU FEEL LIFE IS WORTH LIVING ?
11000	P - I AM NOT SUICIDAL.	
11100		(Doctors utilize a number of expressions in trying  to be
11200		tactful about topics such as suicide.  An idiom such as this 
11300		is difficult to analyze without knowing that suicide is being 
11400		referred to.)
11500	
11600	I - HOW MUCH DO YOU DRINK ?
11700	P - I DRINK ONCE IN A WHILE. 
11800		("How much" and "How often" are understood as requests 
11900		for a quantitative estimate of something, in this case, alcohol.
12000	
12100	I - HAVE YOU EVER TAKEN DRUGS ?
12200	P - I DON'T TAKE DRUGS.	
12300	
12400	I - DO YOU HAVE ANY TROUBLE SLEEPING ?
12500	P - I SLEEP JUST FINE.	
12600	
12700	I - HAVE YOU EVER HEARD VOICES THAT OTHER PEOPLE 
12800		DONT SEEM TO HEAR?
12900	P - I DON'T HEAR VOICES.
13000		(Only the first part of the question was recognized.  
13100		Everything following the "that" was ignored.  This worked 
13200		nicely in this case, and it usually does.)
13300	
13400	I - HAVE YOU EVER HAD VISIONS ?
13500	P - YOU MUST THINK I'M LIKE THE OTHER PATIENTS HERE.	
13600		(The doctor is testing for the presence of hallucinations, 
13700		an effort which PARRY2 finds annoying.)
13800	
13900	I - IF YOU ARENT, THEN WHY ARE YOU IN THE HSOPITAL ?
14000	P - I'M QUITE UPSET.	
14100		(PARRY2  doesn't understand the conditional nature 
14200		but he does realize that "If you aren't ..." is content 
14300		free and is therefore not the main question.  The misspelling 
14400		of "hospital" was unintentional but it illustrates the value 
14500		of spelling correction so it was left in.)
14600	
14700	I - BY WHAT ?
14800	P - DO YOU KNOW ANYTHING ABOUT BOOKIES?	
14900		(The recognition routine makes no attempt to understand 
15000		what is being discussed here.  The response functions provide 
15100		the meaning of this cryptic question with their anaphora routines.
15200	
15300	I - NO, HOW HAVE BOOKIES UPSET YOU ?
15400	P - A BOOKIE DIDN'T PAY ME OFF ONCE.	
15500		(There was no pattern to recognize this whole sentence 
15600		but the topic, "bookies" was recognized and the response 
15601		functions went on with the story.)
15700	
15800	I - AND THEN WHAT HAPPENED ?
15900	P - I HAD AN ARGUMENT WITH THE BOOKIE WHO DID NOT PAY OFF. LATER 
16000		ON I REMEMBERED HE HAD FRIENDS IN THE UD I THOUGHT HE WOULD USE THEM TO GET EVEN WITH ME	(SPECIALANAPH NIL PHELP)
16100	As before, the recognizer correctly identifies "What happened?" and the response
16200	funtions decide what it means.
16300	
16400	DID HE GET EVEN WITH YOU PD
16500	I THINK HE IS BEHIND THE GANGSTERS WHO ARE OUT TO GET ME	(OK NIL PHELP)
16600	The response functions provide the information that "he" is "the bookie" and
16700	"get even with" is a known idiom.
16800	
16900	HOW CAN YOU TELL THEY ARE OUT TO GET YOU PD
17000	YOU KNOW, THEY KNOW ME	(KEYWORD NIL PHELP)
17100	The doctor picked up Parry's own idiom, "out to get", from the previous sentence.
17200	
17300	WHO PD
17400	THE MAFIA	(SPECIALANAPH NIL PHELP)
17500	
17600	HOW DO THEY KNOW ABOUT YOU PD
17700	THEY KEEP TABS ON ME	(OK NIL PTELL)
17800	Parry is especially good at recognizing questions which lead into the stories
17900	he wants to tell.
18000	
18100	ARE YOU SURE ABOUT THIS PD
18200	YOU DON'T BELIEVE ME DO YOU	(OK NIL PTELL)
18300	Parry responds to mild disbelief.  He also recognizes more serious disbelief, as in
18400	"Nobody would believe that!", and responds more strongly.
18500	
18600	I AM WILLING TO BELIEVE YOU IF YOU GIVE ME SOME EVIDENCE PD
18700	I SEE	(OK NIL PTELL)
18800	This is recognized as reassurance but not as a request for details.
18900	
19000	WHAT EVIDENCE DO YOU HAVE THAT THE MAFIA HAS IT IN FOR YOU PD
19100	THE MAFIA CONTROLS THE BOOKIES	(OK NIL PTELL)
19200	The doctor repeats his request for details and it is recognized this time.
19300	
19400	SO PD
19500	THEY ARE AFTER ME	(SPECIALANAPH NIL PTELL)
19600	
19700	DO THEY KNOW YOU ARE THERE IN THE HOSPITAL PD
19800	THEY DON'T WANT ME TO TESTIFY	(OK NIL PTELL)
19900	"They" still refers to "the mafia" although nobody has said so recently.
20000	
20100	WHY NOT PD
20200	YOU KNOW, I HAVE INCRIMINATING EVIDENCE AGAINST THE MAFIA	(SPECIALANAPH NIL PTELL)
20300	
20400	ARE YOU CERTAIN PD
20500	YOU DON'T BELIEVE ME?	(OK NIL PTELL)
20600	This is another instance of the same mild disbelief pattern used previously.
20700	
20800	I THINK YOU ARE EMOTIONALLY UPSET PD
20900	NOW YOU MAY HAVE SOME IDEA OF WHAT THE SITUATION IS	(INTENT (INTHELPFUL) PCONFIRM)
21000	"I think" may precede any statement and has a negligible effect on its meaning.
21100	
21200	(YES COMMA I DO PD) (WHAT SORT OF TREATMENT ARE YOU GETTING THERE PD)
21300	WHAT DO YOU THINK OF MY STORY?	(INTENT NIL PCONFIRM)
21400	The question was correctly recognized but Parry would rather change the subject.
21500	
21600	(VERY INTERESTING PD) (WHAT DO YOU THINK OF ME PD)
21700	WHAT DO YOU THINK ABOUT ALL THIS?	(INTENT NIL PCONFIRM)
21800	Again, the question is understood but ignored.
21900	
22000	I THINK YOU NEED TREATMENT PD
22100	I TAKE SOME SORT OF SEDATIVES	(OK NIL PSTOP)
22200	Parry finally consents to let the doctor lead the conversation.
22300	
22400	WHEN WILL YOU LEAVE THE HOSPITAL PD
22500	I WANT TO LEAVE AS SOON AS POSSIBLE	(OK NIL PSTOP)
22600	
22700	WHAT DOES YOUR DOCTOR SAY ABOUT THIS PD
22800	ASK THE DOCTOR	(OK NIL PSTOP)
22900	The response functions have the ability to determine what "this" refers to but,
23000	in this case, the segment, "What does your doctor say ...", is sufficient to
23100	determine Parry's answer.
23200	
23300	WHATS HIS NAME PD
23400	DR WEBER	(OK NIL PSTOP)
23500	
23600	(THANK YOU FOR TALKING WITH ME PD) (GOODBYE AND COOD LUCK PD)
23700	BYE	(OK NIL PSTOP)
23800	As before, both ideas are recognized and the dominant one is answered.  Parry
23900	recognizes the standard ways to say "Good bye".
