Statistical Induction of Coupled Domain/Range Restrictions from RDF Knowledge Bases

摘要

Statistical Schema Induction can be applied on an RDF dataset to induce domain and range restrictions. We extend an existing approach that derives independent domain and range restrictions to derive coupled domain/range restrictions, which may be beneficial in the context of Natural Language Processing tasks such as Semantic Parsing and Entity Classification. We provide results from an experiment on the DBpedia graph. An evaluation shows that high precision can be achieved. Code and data are available at https://github.com/ ag-sc/SchemaInduction.
