Description

Object Recognition Parser currently uses Inception V3 model for the object classification task. Google released a newer Inception V4 model [1][2].
It has an improved Top -1 accuracy of 80.2 and Top-5 accuracy of 95.2 [3].

I believe that Tika community would benefit from it. I would be working on this issue in the next few days.
