  1. 16. A Hybrid Approach to Hate Speech Detection

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Simon Rickardsson; [2023]
    Keywords : ;

    Abstract : An interesting question is to what extent can background knowledge help in the context of text classification. To address this in more detail, can a traditional rulebased classifier help boost the accuracy of learned models? We explore this here for detecting hate speech and offensive language in online text.
