ADDING SOMETHING OR CHANGING THE EXISTING ARGUMENT IN SOME WAY BY RELATING A CONTRIBUTION TO WHAT'S UM ALREADY ON THE TABLE SO AND THEY'RE THE SEMANTICS OF THE RELATIONS ARE BASED ON THE SEMANTICS OF THE UTTERANCES THAT THEY'RE RELATING AS ALEX S EXPLAINED YESTERDAY UM AND SO UM IT IS IMPORTANT THAT THESE RELATIONS HAVE A SEMANTICS THAT'S TIED TO THE SEMANTICS OF THE UTTERANCES RIGHT YEAH C I JUST THINK WELL I MEAN IT ALL OF THESE THINGS WHEN THEY ENCOUNTER A NEW GENRE OF UM OF UH ACTUAL DATA THEN THEY END UP MODIFYING BUILDING NEW KINDS OF RELATIONS WITH NEW KINDS OF SEMANTICS AND ADDING THEM THAT'S THE ENTIRE HISTORY OF THESE DO THE KIND OF UM TRUTH CONDITIONAL SEMANTICS THAT YOU KNOW ASHER AND LASCARIDES HAVE DONE RIGHT SO THE THEORY CAN HANDLE THE KINDS OF THINGS THAT HAPPEN IN MEETINGS AS SHE EXPLAINED THE ACTUAL COMPUTATIONAL MECHANISMS THEY HAVE CURRENTLY FOR BUILDING UP THE TREES CAN'T NOW I DON'T REMEMBER WAS WHICH SPEAKER YOU IN THE C IN THE EXAMPLE SHE SHOWED YESTERDAY WAS IT THE CASE THAT THE REPRESENTATION OF THE UTTERANCES AND THE RELATIONS INCLUDED WHICH SPEAKER WAS UH I MEAN IT HAD THE AT THE L AT THE LEAVES THEY HAD THE WELL SHE DIDN'T SHOW IT BUT THEY WOULD HAVE THE SEMANTICS OF THE UTTERANCES AND THEN SHE HAD RELATION NAMES AND HANDLES RIGHT I JUST I JUST DON'T DIDN'T REMEMBER SEEING IN THE REPRESENTATION WHICH SPEAKER CONTRIBUTED WHAT 'CAUSE SHE DID REPRESENT UM DISCOURSE STRUCTURES 'CAUSE THESE WERE THE VERBMOBIL SCHEDULING DIALOGUES SO THE UTTERANCES IN THE IN THE REPRESENTATION WERE UTTERED BY TWO DIFFERENT PARTIES THAT WASN'T THE YOU KNOW IN THE IN THE EXAMPLES SHE SHOWED US THERE WERE THERE WAS SOME THAT WAS JUST YOU KNOW ONE PARTY IT WAS A MONOLOGUE BUT THEN THERE WAS A SNIPPET OF DIALOGUE AS WELL WITH SO THERE YOU'VE GOT SOMEBODY WHO'S DOING THEORETICAL DEVELOPMENT THAT WOULD CLAIM THAT YOU DON'T NEED TWO SEPARATE AN ANALYTICAL FRAMEWORKS FOR THESE TWO TYPES OF ACTIVITIES THAT WEI XUN HAS IDENTIFIED YEAH THERE MIGHT BE SOME HIGHER LEVEL STRUCTURE THAT YOU WANNA PULL OUT OF THAT I MEAN I 'CAUSE YOU WERE SAYING YOU'RE JUST GONNA YOU YOU'RE YOU WANNA LOOK AT THIS YOU KNOW VERY LOCAL STUFF BUT FROM THAT YOU C ONE WOULD HOPE YOU WOULD PULL OUT SOMETHING HIGH YOU KNOW NO I THINK WORKING FROM THE BOTTOM UP SOUNDS GREAT YEAH AND MAYBE THERE WAS A LONG BLOW BY BL AND YOU DON'T YOU KIND OF WANNA ABSTRACT AWAY FROM HE SAID THIS SHE SAID THAT HE SAI YOU KNOW TO ANYWAY I YOU KNOW I MEAN I I DON'T THINK ESPECIALLY UH YOU KNOW IF YOU'RE NOT STEEPED IN THESE THEORIES THAT IT MAKES A HUGE DIFFERENCE TO YOU WHETHER WE USE R. S. T. OR SOMETHING LIKE S. D. R. S. BUT IT MIGHT MAKE MUCH MORE YOU KNOW I MEAN I JUST PREFER IT TO BE ONE THING RATHER THAN TWO COMPLETELY SEPARATE THINGS AND THEN THE ADDED EXPLANATION OF WHY IT'S NOT POSSIBLE TO HAVE THE SAME THING APPLIED TO BOTH HALVES TRY TO FIND A THEORY THAT ALLOWS MULTIPLE SPEAKERS AND RELATIONS TO SPAN OVER MORE THAN ONE SPEA YOU KNOW BECAUSE IT IS TRUE THAT I MEAN IF YOU LOOK AT THINGS LIKE DAMSEL AND OTHER ATTEMPTS TO COME UP WITH ANNOTATION SCHEMES FOR FOR DIALOGUE ACTS THERE WAS THIS NOTION OF FORWARD LOOKING AND BACKWARD LOOKING ANYWAY THEY'RE RELATIONAL I MEAN IN SOME WAY YOU KNOW THEY'RE ALL RELATIONAL UM BUT YOU NEEDED BUT THERE'S A DIFFERENT SET OF TAGS IN THERE FROM THE KINDS OF RELATIONS YOU SEE WITHIN R. S. T. FOR EXAMPLE SO IF YOU LOOK AT AMANDA STENT'S THESIS AND THE ANALYSIS THAT SHE DID SORT OF WITHIN A TURN SHE USED SOMETHING LIKE R. S. T. AND THEN ACROSS TURNS SHE USED DAMSEL RIGHT YEAH WHICH WOULDN'T PROBABLY WOULDN'T GIVE US THE KIND OF UM INFORMATION THAT WE NEED ABOUT RELATIONS ACROSS TURNS JUST BECAUSE WE REALLY ARE CRITICALLY INTERESTED IN THE ARGUMENT UM THAT THE GROUP IS BUILDING UP SO THAT WE CAN FIND THE DECISIONS THAT THEY MADE AND UM ANY P UH COUNTER PROPOSALS TO PROPOSALS THAT HAVE BEEN MADE AND THINGS I MEAN IT REALLY IS MORE IN THE SPIRIT UH OF THE R. S. T. ISH RELATIONS THAN UM THAN IN THE DAMSEL KINDS OF RELATIONSHIPS WHAT WE WANT UH OUT OF THE C UM THE RELATIONSHIPS BETWEEN SPEAKERS HERE THEY ARE JOINTLY BUILDING UP AN ARGUMENT STRUCTURE AND THAT IS THE CRITICAL THING THAT WE'RE MISSING IN ORDER TO BE ABLE TO UM UNDERSTAND WHAT'S HAPPENING IN THESE MEETINGS SO WE WOULDN'T WE WOULDN'T WANNA DO THE SAME THING AS WHAT UM SHE DID IN THIS CASE BEC JUST BECAUSE UM DAMSEL DOESN'T GIVE YOU THE RIGHT SORT OF REPRESENTATION BETWEEN SPEAKERS WELL IT GIVES YOU THINGS LIKE ACCEPT AND REJECT AND OH DOES IT OKAY UM I HAVEN'T SEEN IT ON THAT THIS KIND OF DATA SO MAYBE IN FACT R. S. T. DOESN'T GIVE YOU ANYTHING LIKE THAT NO RIGHT OKAY BUT ARE WHAT I MEAN IS YOU KNO WANNA MAKE SURE YOU GET THE ARGUMENTATIVE RELATIONS HOWEVER YOU DO IT WHICHEVER RELATIONS YOU HAVE TO BUILD YOU KNOW NOT I'M NOT SAYING I'M NOT SAYING THAT THERE'S A PARTICULAR SET OF TAGS OR RELATIONS THAT HAVE BEEN DEFINED OUT THERE THAT ARE THE RIGHT ONES I'M JUST SAYING WE NEED THE CORRECT ONES FOR TH THE STRUCTURE THAT WE'RE TRYING TO GET OUT OF THIS 'CAUSE WE NEED CERTAIN INFORMATION OUT OF THIS ANALYSIS THAT YEAH YOU KNOW LIKE SETTING DOWN WHAT THE CONSTRAINTS ARE ON THE ANALYSIS GAME HE'S BEEN LOOKING AT THE DATA OKAY S TO GOOD UM AND THEN AND THEN THERE ARE LOTS OF DIFFERENT THEORIES OF ARGUMENT I MEAN YOU CAN ALSO THINK ABOUT THE SORT OF JOINT PROBLEM SOLVING KINDS OF UM APPROACHES SO YOU KNOW CLARK AND LOCKBAUM AND YOU KNOW THAT THAT KIND OF THING THAT WERE DESIGNED FOR DIALOGUE RIGHT I MEAN AND CAN BE EXPANDED TO MORE THAN TWO PERSONS ACTUALLY THE LOCKBAUM STUFF IS FOR GROUPS MM-HMM YEAH SO YEAH FOR INTERACTIVITY THIS IS A VERY WEAK DEFINITION YEAH IF WE NEED MORE THEN WE MIGHT USE SOME MORE FINER UH F FINER UH DEFINITION FOR INTERACTIVITY WELL WHAT YOU'LL NEED IN THE END IS SOMETHING OPERATIONAL SO IT'S SOMETHING THAT YOU CAN USE TO ACTUALLY SEGMENT MEETINGS INTO THE UM THE AREAS THAT YOU THINK ARE IMPORTANT FOR THIS ANALYSIS RIGHT SO UM IT'S NOT QUITE CLEAR TO ME WHAT THE DIFFERENT KINDS OF THINGS ARE SO IT WOULD BE I THINK HANDY IF YOU COULD TAKE A MEETING AT SOME POINT AND SAY YOU KNOW THIS IS A INTERACTIVE AREA AND THIS IS A MONO LOGIC AREA BECAUSE AND WE COULD COME UP WITH WHAT KINDS OF MEASUREMENTS YOU NEED UM I MEAN WE HAVE W WE HAVEN'T DONE PAST WORK HERE ON SEGMENTING MEETINGS IN THAT WAY
