  11. How to Scrape? 
 Google Play example 
 Goal: collect the network of similar apps https://play.google.com/store/apps/details?id= com.shazam.android https://play.google.com/store/apps/details?

  12. Popular Scraping Libraries Selenium . Supports multiple languages. http://www.seleniumhq.org 
 Beautiful Soup . Python. https://www.crummy.com/software/BeautifulSoup 
 Scrapy . Python. https://scrapy.org 
 JSoup . Java. https://jsoup.org Important considerations: Different web content shows up depending on web browsers used 
 Scraper may need different “web driver” (e.g., in Selenium), or browser “user agent” Data may show up after certain user interaction (e.g., click a button) • Scraper may need to simulate the actions. • Selenium supports more actions than beautiful soup:
