Leveraging Wikipedia Table Schemas for Knowledge Graph Augmentation
Listed in Borealis and Agri-environmental Research Data Dataverse — shown once because both records carry DOI 10.7939/dvn/f36tgc
General solutions to augment Knowledge Graphs (KGs) with facts extracted from Web tables aim to associate pairs of columns from the table with a KG relation based on the matches between pairs of entities in the table and facts in the KG.
Description
These approaches su er from intrinsic limitations due to the incompleteness of the KGs. In this paper we investigate an alternative solution, which lever- ages the patterns that occur on the schemas of a large corpus of Wikipedia tables.
Our experimental evaluation, which used DBpedia as reference KG, demonstrates the advantages of our approach over state-of-the-art solutions and reveals that we can extract more than 1.7M of facts with an estimated accuracy of 0.81 even from tables that do not expose any fact on the KG.
