BIG DATA ANALYSIS

Report on Natural Language processing within Big Data Analysis

Introduction:
The paper entails a detailed discussion and analysis of “Natural Language Processing” within Big Data analysis. Big Data Analysis is basically referred to as the use of various advanced “analytical techniques” against very large and diverse sets of data and which tends to include “semi-structured”, ‘structured”, and “unstructured data” (Ghavami, 2019). These data have a wide range of sources that vary in size tremendously starting from terabytes to zettabytes. Continue reading
