  for inread in content.splitlines():
      m=json.loads(inread)
      extracted=m['text'].lower()
      tokenized= nltk.word_tokenize(extracted)
      for word in tokenized:
          nplist=[]
          if my_dict2.get(word) is not None:
              sequence.append(word)
              nplist.append(sequence)
              A = numpy.array(nplist)
              b=Counter(A.flat)
              z=b.most_common(5)
              x.append(z)
  
  sequence[:]
