Combining multiple prioritized knowledge bases by negotiation

Guilin Qi, Weiru Liu, David Bell
2007 Fuzzy sets and systems (Print)  
Recently, several belief negotiation models have been introduced to deal with the problem of belief merging.  ...  This step is based on a prioritized belief negotiation model.  ...  However, both Konieczny's belief negotiation model and Booth's belief negotiation model are defined in purely propositional logic systems. Therefore it is difficult to define a weakening function.  ...

Combining Multiple Knowledge Bases by Negotiation: A Possibilistic Approach [chapter]

Guilin Qi, Weiru Liu, David A. Bell
2005 Lecture Notes in Computer Science  
A negotiation model consists of two functions: a negotiation function and a weakening function.  ...  This step is based on a prioritized belief negotiation model.  ...  However, both Konieczny's belief negotiation model and Booth's belief negotiation model are defined in purely propositional logic systems. So it is difficult for them to define a weakening function.  ...

A Model for the Integration of Prioritized Knowledge Bases Through Subjective Belief Games

Ebrahim Bagheri, Ali A. Ghorbani
2010 IEEE transactions on systems, man and cybernetics. Part A. Systems and humans  
Various belief merging models have been developed that use a belief negotiation game to address this problem. These models often consist of two key functions, namely: negotiation, and weakening.  ...  A negotiation function finds and selects the weakest belief bases among the available belief bases, and then a weakening function removes the least valuable set of information from the selected belief  ...  Konieczny's Belief Game Model (BGM) [2] and Booth's Belief Negotiation Model (BGM) [3, 6] are among the most popular frameworks for belief merging, which are defined for a pure propositional logic  ...

Towards a Belief-Theoretic Model for Collaborative Conceptual Model Development

Ebrahim Bagheri, Ali A. Ghorbani
2008 Proceedings of the 41st Annual Hawaii International Conference on System Sciences (HICSS 2008)  
Based on this construct, methods for negotiating over and merging of conceptual models are proposed.  ...  Merging and integrating different conceptual models which have been developed by domain experts and analysts with dissimilar perspectives on the same issue has been the subject of tremendous amount of  ...  In this section, we will describe how various conceptual models originating from different viewpoints can be merged on the basis of negotiation, consensus building, and model pruning.  ...

Integrating Subjective Knowledge Bases through an Extended Belief Game Model

Ebrahim Bagheri, Ali A. Ghorbani
2008 2008 Seventh Mexican International Conference on Artificial Intelligence  
Various belief merging models have been developed to address this problem. These models often consist of two key functions, namely: negotiation, and weakening.  ...  A negotiation function finds the weakest belief bases among the available belief bases, and then the selected belief bases concede based on a weakening function.  ...  Konieczny's belief negotiation model [27] and Booth's belief negotiation model [13, 12] are among the most popular frameworks for belief merging, which are defined for a pure propositional logic setting  ...

Belief base merging as a game

Sébastien Konieczny
2004 Journal of Applied Non-Classical Logics  
Those operators can be seen as a special case of Booth's Belief Negotiation Models [BOO 02], but the achieved restriction forms a consistent family of merging operators that worths to be studied on its  ...  This idea leads to numerous new interesting operators (depending of the exact meaning of "weakest" and "concede", that gives the two parameters for this family) and opens new perspectives for belief merging  ...  Acknowledgements The author wish to thank Richard Booth for hepful discussions and for its comments on a previous version of this paper, the anonymous referees for their interesting comments and Anthony  ...

Social contraction and belief negotiation

Richard Booth
2006 Information Fusion  
We consider both a postulational and a procedural approach to social contraction. The latter builds on the framework of belief negotiation models (Booth 2001) .  ...  How should the agent merge these items of information into a single, consistent piece?  ...  From now on when we write "belief negotiation model" we will mean an extended belief negotiation model in the sense of the above definition. 4 A belief negotiation model N then uniquely determines, for  ...

A belief-theoretic framework for the collaborative development and integration of para-consistent conceptual models

Ebrahim Bagheri, Ali A. Ghorbani
2009 Journal of Systems and Software  
Based on this construct, methods for formally negotiating over and merging of conceptual models are proposed.  ...  Merging and integrating different conceptual models which have been collaboratively developed by domain experts and analysts with dissimilar perspectives on the same issue has been the subject of tremendous  ...  The viewpoints can gradually adjust their belief values and use the belief and proposition recommendation procedures to form a formal negotiation process and finally settle on an agreed set of specifications  ...

Dynamics of Beliefs [chapter]

Sébastien Konieczny
2011 Lecture Notes in Computer Science  
In this paper we give a quick overview of the main operators for belief change, in particular revision, update, and merging, when the beliefs are represented in propositional logic.  ...  And we discuss some works on belief change in more expressive frameworks.  ...  Several works have tried to use tools from belief change theory in order to modelize abstract negotiation processes [14-16, 68, 59, 50, 38] .  ...
