Big Data Science Over the Past Web [chapter]

Miguel Costa, Julien Masanès
2021 The Past Web  
This can be a slow and superficial process when analysing complex topics, due to the huge amount of data that web archives have been preserving over time.  ...  As a result, researchers such as historians and sociologists have used web archives as a source of information to understand the recent past since the early days of the World Wide Web.  ...  Big data approaches are therefore a natural fit for web archives.  ...
