Input: READING, ,
Output: aggregated STAY; SEQ
Begin
   For each record’s in READING do

     Repair and aggregate ’s timestamp by grouping into STAY;
    Else Repair and aggregate ’s timestamp by grouping the parent of into STAY;
  End if
  If includes ’s node //aggregate nodes
     Aggregate ’s node by grouping into STAY;
  Else Aggregate ’s node by grouping the parent of into STAY;
