EMMA@SU-CSLI.ARPA (06/26/84)
From: Emma Pease <EMMA@SU-CSLI.ARPA> [Forwarded from the CSLI Newsletter by Laws@SRI-AI.] The following will take place on Friday, June 29 in the Ventura Conference room from 2:00 to 4:00 (followed by tea). THE DIALOG SYSTEM HAM-ANS: NATURAL LANGUAGE ACCESS TO DIVERSE APPLICATION SYSTEMS (H. Marburger, K. Morik, B. Nebel) -- St This talk will introduce the overall goals of the NL-System HAM-ANS (HAMburg Application-oriented Natural language System) which is currently being developed at the University of Hamburg. HAM-ANS encompasses three different application classes: natural language access to a vision system (traffic at a street crossing), to a relational database system (fishery data), and for guiding a competitive dialog with a client (hotel reservation situation). The system accepts typed input in colloquial German and produces typed German responses. The system's general architecture and knowledge sources will be introduced. USER MODELING, EVALUATION STANDARDS, AND DIALOGUE STRUCTURE -- THE HAM-ANS APPROACH (Katharina Morik) -- AI dialogue systems are now developing from question-answering systems toward advising systems. This includes: * structuring dialog * understanding and generating a wider range of speech acts than simply information request and answer * modeling the user's familiarity with the system, his/her state of knowledge about the domain, and his/her evaluation standards (goals) In this talk, first the field of user modeling is structured according to the different aspects of the user (familiarity, knowledge, evaluation). We may then, secondly, describe our ongoing work in this field and relate it to other approaches. User modeling in HAM-ANS is closely connected to dialog structure and dialog strategy. In advising the user, the system generates the verbalizes speech acts. The choice of the speech act is guided by the user profile and the dialog strategy of the system.
