Fault-tolerant semantic mappings among heterogeneous and distributed local ontologies

Abdul-Rahman Mawlood-Yunis
2008 Proceeding of the 2nd international workshop on Ontologies and nformation systems for the semantic web - ONISW '08  
All of the precedent research related to semantic mapping faults demonstrates one significant shortcoming.  ...  The current research examines the destructive effect of semantic mapping faults on the Emerging Semantics, i.e. bottom-up construction of ontology and proposes a solution to detect temporal semantic mapping  ...  The existing research related to semantic fault suggests that the conflicts are mainly due to the heterogeneous representation of information created by autonomous and independent information source providers  ...
