Faster than FOI and more detailed than advanced search techniques, scraping also allows you to grab data that organisations would rather you didn’t have – and put it into a form that allows you to get answers.
Scraping – getting a computer to capture information from online sources – is one of the most powerful techniques for data-savvy journalists who want to get to the story first, or find exclusives that no one else has spotted.
Paul Bradshaw will show you how to scrape content from the web and find stories that otherwise you might have been missed.
This two-day workshop in scraping is designed for reporters with no knowledge of scraping or programming and provides essential skills for getting original stories by compiling data across a range of online sources. By the end of the workshop, you will be able to use specialist scraping tools (without programming) and begin to write your own, more advanced, scrapers. You will also be able to communicate with programmers on relevant projects. (See below for more information and technical requirements – you must bring your own laptop).

2-5pm Project surgery: your scraping challenges
Scraping is the process of automatically collating information from the web. It might be grabbing entries across hundreds of webpages, fetching and combining dozens of spreadsheets, or thousands of PDFs.
The results have led to exclusive stories for organisations ranging from the Bureau of Investigative Journalism and Trinity Mirror, to DC Thomson, Channel 4 and the BBC.
Delegates will be using their own laptop and should have a Google drive account, and have downloaded the free version of outwit hub
ahead of the course. A GitHub account would also be useful.
The software is all free. However the free version of OutWit Hub only allows you to scrape 100 rows, so you may want to pay for the full version but can decide after you’ve learnt how to use it on the course.
This course is now full. If you’d like to register your interest for further courses, please email tom [at] tcij.org.
