====== Learning goals ======

In our digital society, every human activity is mediated by information technologies, hence leaving digital traces behind. These massive traces are stored in some, public or private, repository: phone call records, movement trajectories, soccer-logs and social media records are all examples of “Big Data”, a novel and powerful “social microscope” to understand the complexity of our societies. The analysis of big data sources is a complex task, involving the knowledge of several technological and methodological tools.
This course has three objectives: 

  * introducing to the emergent field of big data analytics and social mining; 
  * introducing to the technological scenario of big data, like programming tools to analyze big data, query NoSQL databases, and perform predictive modeling;
  * guide students to the development of a open-source and reproducible big data analytics project, based on the analyis of real-world datasets. 

====== Module 1: Big Data Analytics and Social Mining ======
In this module, analytical methods and processes are presented thought exemplary cases studies in challenging domains, organized according to the following topics: 

  * The Big Data Scenario and the new questions to be answered
  * Sport Analytics:   
    - Soccer data landscape and injury prediction
    - Analysis and evolution of sports performance
  * Mobility Analytics
    - Mobility data landscape and mobility data mining methods
    - Understanding Human Mobility with vehicular sensors (GPS)
    - Mobility Analytics: Novel Demography with mobile-phone data 
  * Social Media Mining
    - The social media data landscape: Facebook, Linked-in, Twitter, Last_FM
    - Sentiment analysis. example from human migration studies
    - Discussion on ethical issues of Big Data Analytics
  * Well-being&Now-casting
    - Nowcasting influenza with retail market data
    - Predicting well-being from human mobility patterns
  * Paper presentations by students


====== Module 2: Big Data Analytics Technologies ======
This module will provide to the students the technologies to collect, manipulate and process big data. In particular the following tools will be presented: 

  * Python for Data Science
  * The Jupyter Notebook: developing open-source and reproducible data science 
  * MongoDB: fast querying and aggregation in NoSQL databases
  * GeoPandas: analyze geo-spatial data with Python
  * Scikit-learn: programming tools for data mining and analysis
  * M-Atlas: a toolkit for mobility data mining 


====== Module 3: Laboratory for Interactive Project Development  ======
During the course, teams of students will be guided in the development of a big data analytics project. The projects will be based on real-world datasets covering several thematic areas. Discussions and presentation in class, at different stages of the project execution, will be performed. 

  * Data Understanding and Project Formulation
  * Mid Term Project Results 
  * Final Project results
