Popis: | Ontology is one of the fundamental cornerstones of the semantic Web. The pervasive use of ontologies in information sharing and knowledge management calls for efficient and effective approaches to ontology development. Ontology learning, which seeks to discover ontological knowledge from various forms of data automatically or semiautomatically, can overcome the bottleneck of ontology acquisition in ontology development.. In this article a novel automated method for ontology learning is proposed. First, domain-related documents were collected. Secondly, the C-value method was implemented for extracting meaningful terms from documents. Then, an ART neural network was used to cluster documents, and terms’ weight was calculated by TF–IDF method in order to find candidate keyword for each cluster. Next, the Bayesian network and lexico-syntactic patterns were applied to construct the initial ontology. Finally, the proposed ontology was evaluated by expert's views and using the ontology for query expansion purpose. The primary results show that the proposed ontology learning method has higher precision than similar studies. |
