RT Journal Article T1 A Big Data Platform for Real Time Analysis of Signs of Depression in Social Media A1 Martínez Castaño, Rodrigo A1 Pichel Campos, Juan Carlos A1 Losada Carril, David Enrique K1 Social Media K1 Text mining K1 Depression K1 Public health surveillance K1 Stream processing K1 Real-time processing AB In this paper we propose a scalable platform for real-time processing of Social Media data. The platform ingests huge amounts of contents, such as Social Media posts or comments, and can support Public Health surveillance tasks. The processing and analytical needs of multiple screening tasks can easily be handled by incorporating user-defined execution graphs. The design is modular and supports different processing elements, such as crawlers to extract relevant contents or classifiers to categorise Social Media. We describe here an implementation of a use case built on the platform that monitors Social Media users and detects early signs of depression PB MDPI YR 2020 FD 2020 LK http://hdl.handle.net/10347/23770 UL http://hdl.handle.net/10347/23770 LA eng NO Martínez-Castaño, R.; Pichel, J.C.; Losada , D.E.
