[BiO BB] Need help on batch query on GO ontology

[Raja Loganantharaj]

I have a set of GO IDs for a set of genes and I would like to obtain 
their taxonomical GO hierarchy. The GO portal allow single ID at a time. 
Is there any API or software from which I enter or read in the set of GO 
ID or genes so that I get the clustered output based on their 
function(say). I have tried DAVID.

Thanks and I appreciate you sharing your experience.
