SQL:
SELECT DISTINCT COUNT ( t4.paperid )  ,  t3.authorid FROM paperkeyphrase AS t1 JOIN keyphrase AS t2 ON t1.keyphraseid  =  t2.keyphraseid JOIN paper AS t4 ON t4.paperid  =  t1.paperid JOIN writes AS t3 ON t3.paperid  =  t4.paperid WHERE t2.keyphrasename  =  "syntactic parsing" GROUP BY t3.authorid ORDER BY COUNT ( t4.paperid ) DESC;
