3 Data Analysis For each of the extracted texts from the article, perform textual analysis and compute variables, given in the output structure excel file. You need to save the output in the exact order as given in the output structure file, “Output Data Structure.xlsx” NOTE: YOU MUST USE PYTHON PROGRAMMING FOR THE DATA ANALYSIS

4 Variables Definition of each of the variables given in the “Text Analysis.docx” file. Look for these variables in the analysis document (Text Analysis.docx):

1. POSITIVE SCORE
2. NEGATIVE SCORE
