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, 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 reproducible big data analytics project, based on the analysis of big real-world datasets.
This course is meant to put at work the many data analytics technologies and competences: data mining, machine learning, social network analytics, visual analytics in realizing a whole Big data analytics project: from acquiring and analyzing big data from multiple sources to the purpose of discovering the patterns and models that explain certain phenomena, till the validation and presentation of the discoveries and the interpretation of the predictions.
The students will be exposed to experience in different domains: mobility and transportation, urban planning, demographics, economics, social relationships, opinion and sentiment, etc.; and on the analytical and mining methods that can be used.
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, perform predictive modeling, and interpret/explain predictions;
- guide students to the development of a reproducible big data analytics project, based on the analysis of big real-world datasets.
The assessment of the course consists of: (i) the presentation of a paper in the literature showing a real-world example of big data analytics project; (ii) the development, during the course, of a big data analytics project in team with other students; (iii) an oral exam where the student describes the developed project, the motivations behind it and the results obtained. During the oral exam the student must be able to demonstrate knowledge of the course contents and be able to discuss the topics thoughtfully and with propriety of expression.
