  2. 2. Hawkes Processes on Socialand Mass Media: : A Causal Study of the #BlackLivesMatter Movement inthe Summer of 2020

    University essay from Uppsala universitet/Statistik, AI och data science

    Author : Alfred Minh Lindström; [2023]
    Keywords : ;

    Abstract : In this work we study interactions in social media and the reports in mass media during the Black LivesMatter (BLM) protests following the death of George Floyd. We implement open-source pipelines to process the data at scale and employ the self-exciting counting process known as Hawkes process to address our main question: is there a causal relation between interactions in social media and reports of street protests in mass media? Specifically, we use distributed label propagation to identify such interactions in Twitter, that supported the BLM movement, and compared the timing of these interaction to those of news reports of street protests mentioning George Floyd, via the Global Database of Events, Language, and Tone (GDELT) Project.

  3. 3. Semi-supervised Sentiment Analysis for Sentence Classification

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Eirini Tsakiri; [2022]
    Keywords : sentiment analysis; text classification; semi-supervised learning; machine learning;

    Abstract : In our work, we deploy semi-supervised learning methods to perform Sentiment Analysis on a corpus of sentences, meant to be labeled as either happy, neutral, sad, or angry. Sentence-BERT is used to obtain high-dimensional embeddings for the sentences in the training and testing sets, on which three classification methods are applied: the K-Nearest Neighbors classifier (KNN), Label Propagation, and Label Spreading.
