title: convert RDB to RDFand mapping two graphs to extract domain terms
body: <p>I have a table,that stores resources and their tags from social network (bibsonomy)</p>
  
  <p>and i have SPARQL results  from dbpedia by <a href="http://dbpedia.org/sparql" rel="nofollow">Virtuoso SPARQL Query Editor</a></p>
  
  <p><a href="http://dbpedia.org/page/Category:Web_design" rel="nofollow">RDF result page</a></p>
  
  <p>Now, i want to convert that table to RDF graph where every node represents set of tags of a shared resource, then i want to use this rdf result about web_design categories from dbpedia as seed to extract related tags to web design domain .
   i don't know what is the best way and tools to do that .</p>
