Abstract
From small research groups to large organizations, there has been tremendous effort in the last few years in publishing data online so that it is widely accessible to a large community. These efforts have been successful across a number of domains and have resulted in a proliferation of online sources. In the field of biology, there were 1.330 major online molecular databases at the beginning of 2011, which is 96 more than a year earlier. In the Linking Open Data (LOD) community project at the W3C, the number of published RDF triples has grown from 500 million in May 2007 to over 28 billion triples in March 2011. Fueling this data publishing explosion are tools for translating relational and semistructured data into RDF. In this chapter, we present LinQuer, a generic and extensible framework for integrating link discovery methods over relational data.
