In an agent-based cloud scenario, when two agents, provided with different ontologies exchange messages to negotiate a Service Level Agreement for a cloud service, they could fail to understand both the correct meaning of their messages and the offered service quality, due to the differences present in their ontologies.

Abstract
In an agent-based cloud scenario, when two agents, provided with different ontologies exchange messages to negotiate a Service Level Agreement for a cloud service, they could fail to understand both the correct meaning of their messages and the offered service quality, due to the differences present in their ontologies. In all these cases, a semantic negotiation is required to reciprocally making understandable the messages exchanged about the cloud service characteristics. In this work we propose a protocol for supporting the SLA negotiation process, involving semantic issues, which do not require the use of a common global agent ontology sharing knowledge in advance. In detail, this protocol considers that each agent is able to partition the other agents based on both their expertise in cloud services and similarity with their own ontologies.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
