Abstract:

Construction of business ontologies from news sources can produce a detailed representation of the chosen area, but the ontology may over time gather errors because information can become rapidly outdated. The two stage strategy described in this paper attempts to identify outdated relations in an ontology by affixing a confidence score to each relation and decaying the relation until a preset value where it is deleted or archived. The relation score is refreshed if the information is repeated in a news story. An evaluation demonstrates that over time erroneous information is removed and new information is added to the ontology.

More about this publication?

• International Journal of Metadata, Semantics and Ontologies aims at publishing research advances and discussions about meta-data in a broad sense, and about their associated semantics and ontological structures, from a multi-disciplinary perspective, and with an emphasis on domain-specific ontologies and organisational, human interaction and social issues regarding metadata annotation, use and assessment. It also intends covering Semantic Web research, as a concrete metadata-intensive technological framework in which shared and standardised semantics are a critical issue.
