These are the data preparation and analysis Jupyter notebooks accompanying Nicholls (2019) Detecting Textual Reuse at Scale, in the International Journal of Communication. The first notebook shows the steps for building the database of news content data which this notebook relies upon, the second carries out the analyses from the paper. Although this sets out all the steps required to implement the method, there are two important issues to be aware of: The source data (newspaper articles) are not included as they are copyright encumbered There are many things that could be done better a second time around If you want to reimplement the method, please do be in touch: tom.nicholls@politics.ox.ac.uk
