I have submitted a paper to a conference with a rebuttal phase. I have received the first round of reviews, and should be writing an answer which addresses issues raised by the reviewers.
I have received two very positive evaluations, with one accept and one weak accept. The third review however was -2 (reject).
The reviewer that rejected the paper did so under the argument that the paper defined a nice problem, but "without interest for the community of the conference". He also tried to shift the focus of the paper from the main result to a very auxiliary result by treating the auxiliary result as if it were the main.
1) Would it be worth to send an email to the conference chairs asking for a fourth review?
2) What would be the likelihood that the chairs would do that?
3) In case the fourth review is positive, would it have the potential to be taken into consideration when accepting/rejecting the paper?
