Team project for the module of Web Mining, as part of the program Mannheim Master in Data Science of the University of Mannheim, during the summer semester of 2022. In this work, Graph Neural Networks and traditional Machine Learning approaches were exploited to predict the importance a paper will have once it is published, given the citation network.
Team project for the module of Information Retrieval and Web Search, as part of the program Mannheim Master in Data Science of the University of Mannheim, during the summer semester of 2022. In this work, traditional IR approaches such as TF-IDF and BM-25, as well as recent embedding techniques, such as GloVe, BERT and BART, were exploited in a Learning to Rank algorithm for document retrieval.
Final project for the module of Automated Media Content Analysis, as part of the program Mannheim Master in Data Science of the University of Mannheim, during the winter semester of 2021/22. The sentiment of headlines and snippets from The New York Times articles concerning two United States presidents (Donald Trump and Joe Biden) in their first year of government were analyzed with NLP techniques.
