i think one of the important feature would be the query processor for
automatic query formation. this will involve making query processor
UNDERSTAND the data in GGG and the context in which query is asked.


however in the semantic web i havn't found anything directed at automatic
query formation. extracting any peice of information requires knowledge of
structure of data(ontology) and hand coding the query to SQARQL equivalant.
has any work being been done previously on auto query generators ?
