question and answering supporting facts generation Knowledge Base data-to-text

In this study, we intend to create supporting facts from the knowledge base to add information to the question and answer process, and provide a form that is easy for humans to read. Data from two knowledge bases, DBpedia and Wikidata, related to supporting documents in HotpotQA were collected through crawling, and the supporting facts generators were trained using collected triples. The answer generator was trained with generated supporting facts and questions as inputs. Regardless of both DBpedia and Wikidata, supporting facts generated based on the knowledge base improved answer generation performance by providing positive additional information about questions, and generated human-understandable sentences.
