## File Description

USEFUL_FILES
      -> regexList- Contains the regex for the company name to enhance search results and get more relevant results.
      -> search_scrape.py- Scrapes urls from the google search results.
      -> filter.py- Filters the relevant urls collected from google search results.
      -> archive_scraper.py - Scrapes urls from archives of various websites.
      -> scrape_with_bs4.py- Scrapes the content from the scraped urls.
      -> quick_scraper.py- Scrapes content parallely and faster by sending multiple requests per second.
      -> merger.py- Merges the data collected from google search results and news archive.
      -> sentiment.py - Calculates the sentiment of the collected data.
      
  
## Note

* RegexList is used to fetch more relevant urls from the archives and not from the google search results. So there should be consistency in the names of company used across google search ( search_scrape.py ) and those mentioned in the regexList.
