Ontologies are not the Panacea in Data Integration: A Flexible Coordinator to Mediate Context Construction [chapter]

Aris M. Ouksel, Iqbal Ahmed
1999 Ontologies and Databases  
Their limitations are illustrated through a conceptual analysis of several prominent examples used in heterogeneous database systems and in natural language processing.  ...  Shared ontologies describe concepts and relationships to resolve semantic conflicts amongst users accessing multiple autonomous and heterogeneous information sources.  ...  The mediator in COIN is based on Wiederhold's context mediator concept [23] , and utilizes a theory of semantic values as a unit of data exchange among heterogeneous information systems (HIS).  ...

An Approach to Composing Web Services with Context Heterogeneity

Xitong Li, Stuart Madnick, Hongwei Zhu, Yushun Fan
2009 2009 IEEE International Conference on Web Services  
However, existing initiatives of Semantic Web Services (SWSs) often ignore context heterogeneity. In this paper, we introduce an approach to address this issue.  ...  Given a BPEL file that ignores context heterogeneity, the approach automatically detects all context differences among the involved services, and reconciles them by producing a mediated BPEL file that  ...  Also, the authors thank Frank Manola for his valuable suggestions in improving the work.  ...

Semantic conflict resolution ontology (SCROL): an ontology for detecting and resolving data and schema-level semantic conflicts

S. Ram, Jinsoo Park
2004 IEEE Transactions on Knowledge and Data Engineering  
SCROL provides a dynamic mechanism of comparing and manipulating contextual knowledge of each information source, which is useful in achieving semantic interoperability among heterogeneous databases.  ...  Establishing semantic interoperability among heterogeneous information sources has been a critical issue in the database community for the past two decades.  ...  Their valuable comments and suggestions greatly improved the quality of this paper.  ...
