February is All about Data Scraping - #DataInTheWild
This month we are looking at Data Scraping (collecting data from the web itself). The web is full of data in all shapes and forms that are just waiting to be ‘caught’ by you. From the page listing of all the waterproof jackets on Berghaus website, to the list of explorers in Wikipedia; from the reviews of the best places to stay in the Amazon on TripAdvisor to tweets about the Northern Lights. Yes, this month we are dusting off our hiking boots, busting out our binoculars, and heading off in search of #DataInTheWild!
What is Data Scraping?
Web pages contain a wealth of information, but this is usually locked-up in not-very-human-friendly text-based mark-up languages (such as HTML). Scraping lets you extract the data from web pages (be they in HTML, JSON, or a range of other different formats), and transform this data into something that a human can understand. “But isn’t scraping hard?” I hear you cry. The answer is “no, it doesn’t have to be”. Just as Tableau makes visualizing your data a breeze, there are many tools (like Import.io) that make data scraping only a click away. Even when you need to be able to code there are now many great resources that can help you learn to code (check out our post from January Learn to be a Python Charmer), and many resources like coding collaboration site GitHub where you can find code to help you get started.
be like Ash Ketchum from Pokemon and catch all the data!
