  2. 2. Machine Learning for Detecting Hate Speech in Low Resource Languages

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :David Rodriguez; Denitsa Saynova; [2020-07-08]
    Nyckelord :machine learning; natural language processing; BERT; cross-lingual zeroshot learning; data augmentation; hate speech; classification; Twitter;

    Sammanfattning : This work examines the role of both cross-lingual zero-shot learning and data augmentationin detecting hate speech online for low resource set-ups. The proposedsolutions for situations where the amount of labeled data is scarce are to use alanguage with more resources during training or to create synthetic data points. LÄS MER

  3. 3. Text analysis for email multi label classification

  5. 5. Conversational agents in a family context : A qualitative study with children and parents investigating their interactions and worries regarding conversational agents

    Master-uppsats, Umeå universitet/Institutionen för informatik

    Författare :Arvid Horned; [2020]
    Nyckelord :Conversational Agent; Artificial Intelligence; child-agent interaction; Families;

    Sammanfattning : Conversational agents such as Siri, Google and Alexa are growing in popularity, and Artificial Intelligence in the form of natural language processing utilized by these agents is becoming more available and capable with time. Understanding how conversational agents are used today and what implications it has for our daily lives is important if this trend is going to continue. LÄS MER
