Anyone may nominate any paper (including self-nominations). Nominations should include two page extended abstract (pdf). Roughly, the first page should summarize the paper and the second should make the case for its impact since publication. If the paper has had impact beyond conventional metrics (e.g., citation count), be sure to highlight it.
Awarding of the prize is contingent upon one of the main authors attending the NVMW 2018 to accept it.
The website for the award is: http://nvmw.ucsd.edu/#awards.
