Professor Amr Magdy has been awarded a new NSF grant to explore "Scalable Noise-filtering and Community Queries on User-generated Data". This project aims to facilitate efficient access for scientists on large repositories of user-generated data. This will help scientists to better make use of such data that is already used in major studies of sociology, behavioral sciences, political sciences, and other disciplines. The project focuses on two categories of queries, noise-filtering queries and community queries, that mitigate significant problems in existing scientific use cases for user-generated data.
