Hi, I just can't understand what the ontology plug-in is for and why would anyone use it. From what I could understand from code, it uses the classes in the specified owl file and uses them as keywords to refine the query. Does this involve re-ranking as well? I tried using an owl file as specified on wiki but it didnt have any effect on the reults. I wonder whats going on. Can anyone who might have used and found it useful explain please?
Thanks, Ravish.
