Integrating Knowledge of City Entities Extracted from DBpedia and GeoLite into the EKOSS Failure Cases Repository to Enhance Semantic Search Capabilities

Domain-specific repositories of manually created semantic descriptors usually contain detailed knowledge with “heavy-weight” semantics about particular aspects of the domain, but they often lack common knowledge about the concepts and entities that are described. Integrating some of this common knowledge into the repository can enhance the capabilities of semantic search in the repository. We use common knowledge about city entities from DBpedia knowledge base and GeoLite city database to enhance the EKOSS failure cases repository, which contains knowledge about failures in engineering. Custom parsers are used to extract common knowledge from the two open data sources, and special semantic descriptors, which we call standard entity statements, are generated from the extracted knowledge. We link the city instances in failure case semantic statements with the standard city entity semantic statements, and we demonstrate the new types of semantic search capabilities that are made possible by the integration of the three semantic resources. *
