Also in ths category you can use Datalift to do naive CSV to RDF and
then SPARQL CONSTRUCT. Also provide a simple GUI to generate part of the
CONSTRUCT queries.

Hey Ying,
why don't you just convert CSV to "raw" RDF and then do the mapping,
using SPARQL 1.1?
Google Refine with RDF extension should be enough to do the first step:

Hi,
I am looking for a open source software to convert csv file to RDF
based on one pre-defined ontology. Also, this converter should
support complicated SQL queries (e.g., Group BY query and
IF/THEN/ELSE query) while defining the mapping between csv to our
pre-defined ontology.
thanks
