Semantic Information Brokering: How Can a Multi-agent Approach Help? [chapter]

Amit Sheth, Vipul Kashyap, Tarcisio Lima
1999 Lecture Notes in Computer Science  
This paper discusses whether a multi-agent approach can help achieve semantic information brokering by supporting three of the capabilities needed: (a) extract and use semantic metadata descriptions from  ...  The information brokering architecture provides one approach to addressing issues at data, information and knowledge levels.  ...  We now discuss possible use of a multi-agent system architecture for information brokering with the help of an example.  ...

ICEBERG: Exploiting Context in Information Brokering Agents [chapter]

Catholijn M. Jonker, Arjen Vollebregt
2000 Lecture Notes in Computer Science  
The research reported in this paper has both a scientific and a commercial aim. The scientific interest is to explore the use of contexts in order to improve the quality of information brokering.  ...  In this paper it is shown that contexts in information brokering can be exploited to enable four directions of query reformulation: up and down (standard query expansion) and sideway reformulations of  ...  We also like to thank the anonymous reviewers for pointing out a wealth of literature that we were unaware of. We learnt a lot.  ...

Learning in the Broker Agent [chapter]

Xiaocheng Luan, Yun Peng, Timothy Finin
2003 Lecture Notes in Computer Science  
The agent capability model will be updated using the information from the consumer agent feedback, capability querying, etc.  ...  The solution we propose is to have the broker agent dynamically refine the agent's capability model and to conduct performance rating.  ...  Now we use a similar example to illustrate how the information on local service distribution can help in achieving better matching results.  ...

Intellectual Property Rights Management Using a Semantic Web Information System [chapter]

Roberto García, Rosa Gil, Jaime Delgado
2004 Lecture Notes in Computer Science  
A knowledge oriented approach has been chosen in order to make this development capable of dealing with this complicated domain.  ...  This requirement and the objective of easy Web integration have made the Semantic Web technologies the best choice. NewMARS is a semantics enabled metadata managing system.  ...  Acknowledgements NewMARS is part of the Agent Web project, partly supported by the Spanish administration TIC 2002-01336 (http://dmag.upf.edu/newmars).  ...

Formal Aspects of Grid Brokering

Attila Kertész, Zsolt Németh
2009 Electronic Proceedings in Theoretical Computer Science  
This paper aims at establishing a semantical model for brokering and related activities by defining brokering agents at three levels of the Grid middleware for resource, host and broker selection.  ...  In this paper we focus on a subset of these problems: resource brokering in Grid middleware.  ...  The model presented here is a distributed multi-agent ASM where agents are jobs, i.e. elements from the JOB universe.  ...

Data Brokers: Building Collections through Automated Negotiation [chapter]

Fillia Makedon, Song Ye, Sheng Zhang, James Ford, Li Shen, Sarantos Kapidakis
2004 Lecture Notes in Computer Science  
Since each source-and even each acquisition-may involve a separate negotiation of terms, a collector may prefer to use a broker to represent his interests with owners.  ...  For each acquisition, a negotiation agent is assigned to negotiate on the collector's behalf, choosing from strategies in a strategy pool to automatically handle most bargaining cases and decide what to  ...  Distributed Artificial Intelligence (DAI) and Multi-Agent Systems (MAS) [10] laid important groundwork for agent technology research.  ...

Proximal Business Intelligence on the Semantic Web [chapter]

David Bell, Thinh Nguyen
2010 Lecture Notes in Business Information Processing  
Approaches typically focus on providing mechanisms to improve specific information access and transcoding but not on how the information can be accessed in a mobile, dynamic and ad-hoc manner.  ...  A proof-of-concept mobile and ambient data access architecture is developed in order to further test the viability of such an approach.  ...  In practice, Broker agents in CoBrA are "responsible for maintaining and aggregating a shared model for context information.  ...
