Complex　event　processing　is　a　technology　that　obtains　valuable　complex　events　from　the　low　value　of　single　events,　and　is　widely　used　in　the　network　system　of　big　data　era.　In　order　to　solve　the　need　of　＇rich　the　description　language　of　complex　event＇　and　＇promote　the　efficiency　of　event　stream　pattern　matching＇,　an　original　scheme　of　complex　event　detection　is　proposed　in　this　study.　It　adopts　the　regular　tree　pattern　to　describe　the　complex　events,　which　can　not　only　describe　the　structure　but　also　the　timing　constraints　of　events.　Based　on　the　means　of　tree　ordering,　automaton　and　mapping　table,　the　scheme　combines　data-parallel　and　task-parallel　and　make　full　use　of　the　multi-core　advantage　of　computers.　The　experimental　results　show　that　the　scheme　has　a　high　performance　on　complex　event　detection.　©　2018　Association　for　Computing　Machinery.
