Abstract

Ontologies are a tool for capturing domain knowledge. All ontologies can be considered subjective in regards to the creators view of the domain. This causes difficulty for the purpose of ontology integration. RIPOSTE, a subjective ontology framework, provides the necessary mechanisms to capture the creator and their subjective opinions with each ontological resource they provide. Mappings, between ontologies, are also subjective and can create resultant ontologies that vary depending on the integrating agent, or mapping techniques. To overcome this we extend RIPOSTE to include; mappings between ontologies, subjective opinions and the providing agents. This allows for the combining of mappings from multiple sources, creating an environment that combines the opinions of each agent. This increases the belief of agreed mappings and allows for a threshold filter to only utilise the most popular mappings when integrating the ontologies.
