Changing Ontology Breaks the Queries

Liang, Yaozhong, Alani, Harith and Shadbolt, Nigel (2006) Changing Ontology Breaks the Queries At Doctoral Symp. The 5th International Semantic Web Conference. 05 - 09 Nov 2006. , pp. 982-985.

Record type: Conference or Workshop Item (Paper)


Updating an ontology that is in use may result in inconsistencies between the ontology and the knowledge base, dependent ontologies and applications/services. Current research concentrates on the creation of ontologies and how to manage ontology changes in terms of mapping ontology versions and keeping consistent with the instances. Very little work investigated controlling the impact on dependent applications/services; which is the aim of the system presented in this paper. The approach we propose is to make use of ontology change logs to analyse incoming RDQL queries and amend them as necessary. Revised queries can then be used to query the ontology and knowledge base as requested by the applications and services. We describe our prototype system and discuss related problems and future directions.
