Automatic Evaluation of Ontologies

摘要: We can observe that the focus of modern information systems is moving from “data processing” towards “concept processing,” meaning basic unit processing less and an atomic piece data becoming more a semantic concept which carries interpretation exists in context with other concepts. An ontology commonly used as structure capturing knowledge about certain area by providing relevant concepts relations between them. Analysis textual plays important role construction usage ontologies, especially growing popularity semi-automated (here referred to also learning). Different discovery methods have been adopted for problem [10] including unsupervised, semi-supervised supervised learning over collection text documents, using natural language obtain graph document, visualization extraction find concepts, named entities document collection.
