Recent posts here have discussed ontologies saved in relational databases (see, for example, my September 11 and 24 posts); while other posts have been about different kinds of ontology stores and the Semantic Web (see, for example, my September 27 and 6 as well as my October 11 posts). If one reads only this blog, one might think that there is no work to exploit the advantages of both approaches in a single system afoot. But, there are. A number of investigators are looking into applications that support connections to both a variety of RDBMS schemas and other forms of ontology management.
What if i2b2 built Semantic Web graphs instead of relational stores? What if it had an OWL-defined Ontology, instead of a relational-schema? Click here.
Semantic Web will be part of i2b2 and will allow it to correlate unique variable names across consortium sites (e.g., white, Caucasian) and for information retrieval. Click here
