reasoning on gene ontology

Hi,

Does anyone perform some reasoning using gene ontology? Any intereting
story to share? I recently ran reasoning based on extended GO relations
[1], and found that the triples doubled after reasoning. I was also aware
of some queries are not able to be performed in relational database. but I
havenot found very interesing cases to utlize the inferred results. Any
reference? Thanks.

Best, Bin
