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.
