Human mobility, social networks and big data

Data sources have been evolving the last decades and nowadays a huge amount of
information is available through web navigation. One of the new sources of
information are social networks and they provide large datasets to be studied.
In this context we are using geolocated tweets as a source of information
for mobility patterns. Data retrieval is achieved through public APIs and
smart users selection. Besides, efficient data storage and fast access
to the data is a challenging task for which we rely on NoSQL technology.
