Which machine learning classifier will be used in numerous representation of Arabic corpus datasets. whether the accuracy rate has increased compared to previous research techniques. ?
In this case I would recommend you to take a look on the implementation of Recurrent Neural Networks (RNNs) like the LSTM architecture or Bidirectional RNNs for leveraging the sequence information from the words. There are high-level APIs written in python like keras that you can easily run those models.
This tutorial has the theory and code to implement the LSTM model in python:
