The course will allow students to learn various methods for the design, implementation, and testing of adaptive systems on the Web, created through Artificial Intelligence techniques, with particular reference to Machine Learning techniques. Specific attention will be paid to Information Retrieval systems, such as search engines, crawlers and document feeds. Classic retrieval models will be studied, such as the Vector Space Model and probabilistic models, document ranking techniques, as well as the PageRank algorithm used by Google. Machine Learning methods in Information Retrieval will be addressed, including techniques for Sentiment Analysis, User Modeling methods necessary for personalized search, and social search applications involving communities of individuals in activities such as content tagging and question answering. The techniques for analyzing social networks (e.g., Facebook and Twitter) will be explored, which will allow us to explore phenomena such as the spread of fake news, the filter bubble, and the polarization of users. Finally, Recommender Systems will be studied, from basic algorithms (e.g., collaborative filtering) to application scenarios (e.g., movies, books, music artists and songs).

Programma
The course will examine various methods for designing, implementing, and testing adaptive systems on the Web, realized through Artificial Intelligence techniques. We will pay particular attention to Information Retrieval systems, such as search engines, and new and emerging technologies suitable for developing the next generation of intelligent and personalized search tools. We will study classical retrieval models, such as the vector space and probabilistic models, document ranking techniques, as well as the PageRank algorithm adopted by Google. Algorithms of Machine Learning in Information Retrieval will be addressed, including Sentiment Analysis techniques, User Modeling methods needed for developing personalized research tools, Recommender Systems, and the detection and analysis of Online Communities and Social Networks (such as Facebook and Twitter).Testi Adottati
