A framework for semantic link discovery over relational data

Oktie Hassanzadeh, Anastasios Kementsietsidis, Lipyeow Lim, Renée J. Miller, Min Wang
2009 Proceeding of the 18th ACM conference on Information and knowledge management - CIKM '09  
In this paper, we present a framework for discovery of semantic links from relational data. Our framework is based on declarative specification of linkage requirements by a user.  ...  Many of these data sources are published using tools that operate over relational data stored in a standard RDBMS.  ...  A wide variety of data publishing methodologies based on generation of RDF view over relational data are widely used in these data sources.  ...
