32. Conclusions • Social Media sources can serve as a social sensing platform. • Citizens as sensors. • Real-time monitoring of the Barcelona mobility network. • New route optimizers.
33. Why NoSQL matters? • Hadoop + Mahout for big data and batch processes. • MongoDB for document storage and GeoSpatial Indexing (2D). • REDIS for cache and save HTTP requests. • Neo4j for graphs and operations.
