Imagine designing laws using data – quickly and easily researching, interrogating and understanding the statute book as a whole system. For the first time, the technologies needed to do this have become widely available and reasonably affordable. Moving beyond searching for legal databases for strings of text, the ‘big data for law’ project aims to provide researchers with the data, tools and methods that have the potential to transform how the statute book is conceived and managed. In this poster presentation, John Sheridan, Head of Legislation Services at The National Archives in the UK, will present the work and findings of the big data for law project.
