  • An Automatic Knowledge Graph Creation Framework from Natural Language Text

    KERTKEIDKACHORN Natthawut , ICHISE Ryutaro

    … In this article, we propose T2KG, an automatic KG creation framework for natural language text, to more effectively map natural language text to predicates. … Based on experimental results, the hybrid approach can identify more similar predicate pairs than a baseline method in the predicate mapping task. … Although KG creation is conducted in open domains, in which prior knowledge is not provided, the T2KG still achieves an F1 score of approximately 50% when generating triples in the KG creation task. …
