Web scraping, which is the collection and cleaning of online data, is the first step in any data-driven project. Here’s a short video that explains what scraping is, and how to create automated scraping jobs using a digital tool.
This is a 15-minute video created by an instructor at Ohio State University. In the first six minutes, the instructor talks about why we need web scraping; he then shows how to use a scraping tool, OutWit Hub, to collect data scattered in a large database.
FYI: read reviews by Reporters’ Lab of OutWit Hub and other web scraping tools.
