Methods of managing the evolution of ontologies and their alignments

Abstract Nowadays, none can expect that knowledge about some part of reality will not change. Consequently, a representation such evolving (for example, ontologies) also changes. Such changes entail applications incorporating may become compromised and yield wrong results. An example an application is ontology alignment which be informally described as set connections between two ontologies. Those mark elements from ontologies relate to the same parts reality. In changing one corresponding ontologies, invalid. One designate once again scratch for altered However, approach time resource-consuming. The paper comprehensively presents our evolution maintenance framework. It used preserve validity using only analysis introduced maintained precise definition provided, along with change log. A algorithms allow revalidating alignments have been built based on elements.
