However, emergency response and humanitarian relief organizations that would like to use this information struggle with an avalanche of social media messages that exceeds human capacity to process. Emergency managers, decision makers, and affected communities can make sense of social media through a combination of machine computation and human compassion - expressed by thousands of digital volunteers who publish, process, and summarize potentially life-saving information. This book brings together computational methods from many disciplines: natural language processing, semantic technologies, data mining, machine learning, network analysis, human-computer interaction, and information visualization, focusing on methods that are commonly used for processing social media messages under time-critical constraints, and offering more than 500 references to in-depth information"-- Provided by publisher.CalamitàEffetti socialiBNCFTecnologia dell'informazione e della comunicazione363.3480285CASTILLO,Carlos<1977-743417ITsalbcISBD996226327503316INF01 21221 DISABKDISTRABig crisis data1478862UNISA
