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.  ...

Learning temporal-dependent ranking models

Miguel Costa, Francisco Couto, Mário Silva
2014 Proceedings of the 37th international ACM SIGIR conference on Research & development in information retrieval - SIGIR '14  
Searching on all versions of these files acquired throughout time is challenging, since users expect as fast and precise answers from web archives as the ones provided by current web search engines.  ...  Based on the assumption that closer periods are more likely to hold similar web characteristics, our framework learns multiple models simultaneously, each tuned for a specific period.  ...  Multi-task Learning A temporal-dependent model has two advantages over a model that only learns from data of a segment of time.  ...
