CODE+: Building Common Ontology from Community Knowledge
Dhomas Hatta Fudholi, Wenny J. Rahayu, Eric Pardede · 2017
A domain ontology is an ontology that describes the fundamental knowledge of the domain, including the domain vocabulary, concepts, taxonomy, relations, properties, constraints, and axioms. The creation of a domain ontology may be done manually from scratch by domain experts or translated from existing knowledge sources. Our earlier work in [4] presented a framework on building an ontology by matching and merging existing domain ontologies. In this paper, we expand the framework to include different types of community knowledge representations in a common ontology. A common ontology is a domain ontology that is developed from community knowledge by gathering their commonality. To build a common ontology, we standardize different community data format using a schema mediation notation. We apply rule-based mapping and information extraction methodology, and we perform matching, clustering and merging, to collect common knowledge together. The evaluation shows that our proposed framework can build a valid and rich common ontology.
