Major Steps performed:

• Data Extraction
• Tokenisation and Porter Stemming (Preprocessing)
• Vector Space Modelling (VSM)
• Extract topics from description and title
• LDA
• Similarity Scores computation
• Composer Score and Parameter estimation

Note: The code has been restructured for better view. The paths used in the code might be broken. Correct them before using the code
