Abstract: A data processing system including one or more client devices, wherein each client device is connected to a network system and a data center unit. The data center unit includes a network interface unit, a user interface, one or more storage devices, wherein the one or more storage devices comprise one or more databases. Further, the data center unit includes a storage device controller and database manager for controlling the operation of storage devices and databases, a web server for providing web services to clients, a database server for providing database services to the one or more clients and a machine learning artificial intelligence application server for predicting textual complexity of data. The machine learning artificial intelligence application server includes one or more databases for storing data used to refine textual complexity analysis for improved accuracy of textual complexity predictions.
