    Författare :Drew Perkins; [2020]
    Nyckelord :language; technology;

    Sammanfattning : In this study, I constructed a named-entity linking system that maps between contextual word embeddings and knowledge graph embeddings to predict correct entities. To establish a named-entity linking system, I first applied named-entity recognition to identify the entities of interest. LÄS MER
