User modelling, dialog structure, and dialog strategy in HAM-ANS

Katharina Morik
1985 Proceedings of the second conference on European chapter of the Association for Computational Linguistics -   unpublished
-structuring dialog -understanding and generating a wider range of speech acts than simply information request and answer user modelling User modelling in HAM-ANS is closely connected to dialog structure  ...  In advising the user, the system generates and verbalizes speech acts. The choice of the speech act is guided by the user profile and the dialog strategy of the system.  ...  This paper does not evaluate the overall HAM-ANS but is restricted to the aspect of dialog structuring and user modelling.  ...

User Models in Dialog Systems [chapter]

Wolfgang Wahlster, Alfred Kobsa
1989 User Models in Dialog Systems  
Research within and outside of artificial intelligence which is related to user modeling in dialog systems is discussed.  ...  Although the survey is restricted to user models in naturallanguage dialog systems, most of the concepts and methods discussed can be extended to AI dialog systems in general.  ...  Anticipation Feedback A special case of exploitation of a user model (which is realized in dialog systems like HAM-ANS, NAOS and IMP) is its use in various forms of anticipation feedback loops.  ...

2009 2009 IEEE International Conference on Robotics and Automation  
In this paper we discuss a mixed initiative strategy for robotic learning by interacting with a user in a joint map acquisition process.  ...  In scenarios that require a close collaboration and knowledge transfer between inexperienced users and robots, the "learning by interacting" paradigm goes hand in hand with appropriate representations  ...  "Cognitive Interaction Techology" (CITEC), and the German Service Robotic Initiative (DE-SIRE).  ...

As for a dialog strategy, we introduced a new criterion based on 'efficiency for convergence' and 'consistency with understanding hypotheses' to select an appropriate system response.  ...  We developed a spoken dialog system using these techniques and showed some dialog examples in which misrecognition was naturally corrected.  ...  An example of a dialog. Dialog example Examples of the dialogs with the system are shown in Figure 3 . The user utterance, recognition results, and understanding hypotheses are shown separately.  ...

Attentive History Selection for Conversational Question Answering

Chen Qu, Liu Yang, Minghui Qiu, Yongfeng Zhang, Cen Chen, W. Bruce Croft, Mohit Iyyer
2019 Proceedings of the 28th ACM International Conference on Information and Knowledge Management - CIKM '19  
We show that position information plays an important role in conversation history modeling. We also visualize the history attention and provide new insights into conversation history understanding.  ...  Third, in addition to handling conversation history, we take advantage of multi-task learning (MTL) to do answer prediction along with another essential conversation task (dialog act prediction) using  ...  ACKNOWLEDGMENTS This work was supported in part by the Center for Intelligent Information Retrieval and in part by NSF IIS-1715095.  ...

A speech understanding and dialog system with a homogeneous linguistic knowledge base

M. Mast, F. Kummert, U. Ehrlich, G.A. Fink, T. Kuhn, H. Niemann, G. Sagerer
1994 IEEE Transactions on Pattern Analysis and Machine Intelligence  
To enforce a more model driven strategy neither a left to right nor an island driven strategy is used.  ...  To enable the system to communicate in a spoken dialog with the user, and not only to answer questions like in a question-answer system a dialog component and also an answer generating component are needed  ...  and coeditor of another book on knowledge representation for image understanding and on the architecture of speech dialog systems.  ...

A Conversational Approach to Process-oriented Case-based Reasoning

Christian Zeyen, Gilbert Müller, Ralph Bergmann
2018 Proceedings of the Twenty-Seventh International Joint Conference on Artificial Intelligence  
Process-oriented case-based reasoning (POCBR) supports workflow modeling by retrieving and adapting workflows that have proved useful in the past.  ...  This paper closes this gap and presents a conversational POCBR approach (C-POCBR) in which questions related to structural properties of the workflow cases are generated automatically.  ...  In C-POCBR the users follow the dialog and investigate the presented workflow.  ...

2021 arXiv   pre-print
In the Tenth Dialog System Technology Challenges (DSTC10), we participated in the second Knowledge-grounded Task-oriented Dialogue Modeling on Spoken Conversations.  ...  As a result, GKS outperforms several SOTA models proposed in the data-set on knowledge selection from the Ninth Dialog System Technology Challenges (DSTC9).  ...  Traditionally, TF-IDF technique (Ramos 2003) and language model are applied on similar tasks. As mentioned above, the limitations of previous works lie in the model structure.  ...
