2004 Lecture Notes in Computer Science  
Again, we hope for global properties to emerge from a multiplicity of pair-wise, local interactions, resulting eventually in a self-stabilizing semantic infrastructure.  ...  Since agreements rely on the context of interaction, their boundaries are also fuzzy.  ...  In the context of P2P systems, approaches for achieving multilateral consensus among peers managing structured data have recently been introduced.  ...

On combining a semantic engine and flexible network policies for P2P knowledge sharing networks

S. Castano, A. Ferrara, S. Montanelli, E. Pagani, G.P. Rossi, S. Tebaldi
2004 Proceedings. 15th International Workshop on Database and Expert Systems Applications, 2004.  
The semantic engine exploits peer ontologies for providing a semantically rich representation of peer knowledge, and matching techniques for comparing ontologies of different peers for knowledge sharing  ...  Peer-to-Peer (P2P) systems have recently become popular for content sharing, and a number of different approaches have been studied to perform effective content retrieval in such networks.  ...  According to the considerations presented in Section 4, our future research work will be devoted to evaluate the performance of different P2P architectures for knowledge sharing based on the proposed semantic  ...

2004 Lecture Notes in Computer Science  
Instead, new heuristics based on emerging properties and local consensuses have to be exploited in order to foster semantic interoperability in the large.  ...  Traditional semantic reconciliation techniques, dependent upon shared vocabularies or global ontologies, cannot be used in such open and dynamic environments.  ...  Since agreements rely on the context of interaction, their boundaries are also fuzzy.  ...

A framework for distributed knowledge management: Design and implementation

Giuseppe Pirró, Carlo Mastroianni, Domenico Talia
2010 Future generations computer systems  
The ontology framework allows organizational knowledge to be modeled at different levels. An Upper Ontology is exploited to establish a common organizational knowledge background.  ...  Finally, Personal Ontologies support IKWs in personal knowledge management activities.  ...  The system relies on an automatic mapping algorithm that finds the correspondences among the concepts included in the personal contexts of different users.  ...

S. Castano, A. Ferrara, S. Montanelli, G. Racca
2004 International Conference on Information Technology: Coding and Computing, 2004. Proceedings. ITCC 2004.  
In this paper, we propose a semantic approach for the dynamic resource discovery based on ontologies for a semantically rich description of the metadata characterizing the resources to be shared, and on  ...  semantic matching techniques for dynamically and flexibly comparing ontological resource descriptions against a target resource request.  ...  In a schema-based P2P network, peers can interact searching for semantically related contents with respect to a target request.  ...

2004 Lecture Notes in Computer Science  
In this paper we propose a peer-to-peer architecture (called KEx), which embodies the principle above in a quite straightforward way: (i) each peer (called a K-peer) provides all the services needed to  ...  Management is an approach to knowledge management based on the principle that the multiplicity (and heterogeneity) of perspectives within complex organizations is not be viewed as an obstacle to knowledge exploitation  ...  In this sense, contexts are not to be thought of as an alternative to the use of ontologies in a KM system, but as a necessary integration.  ...
