how many ACL 2012 papers have more than 7 citations ?
SELECT DISTINCT (paper.paperid), COUNT(cite.citingpaperid) FROM cite, paper, venue WHERE paper.paperid = cite.citedpaperid AND paper.year = 2012 AND venue.venueid = paper.venueid AND venue.venuename = 'ACL' GROUP BY paper.paperid HAVING COUNT(cite.citingpaperid) > 7
