I had a similar idea when I created a text annotation service for the biomedical domain. For example:

http://whatizit.neurocommons.org/index.py/pmid?pipeline=whatizitEBIMedDiseaseChemicals&query=17477962&format=atag
(can be quite slow to respond)

This contains recognized entities embedded via RDFa. In this case, each sentence is represented as a sioc:Item and the entities within the sentence are represented as sioc:topics of the sentence.

The RDF of the example above looks like this:
http://tinyurl.com/ydayqr3

However, the entities are taken from ontologies in the Open Biomedical Ontologies (OBO) collection, and not DBpedia. Entity recognition is based on another bioinformatics server, and I cannot just add DBpedia as a vocabulary.

Why? You could include it as RDFa markup around pieces of the text that are not visible in the browser?
