Abstract
A method for auto-correcting information extracted by an open information extraction system includes inputting an input triple extracted from an input sentence to a grammaticality model trained to output whether the input triple is grammatical or ungrammatical. The input triple is corrected based on the grammaticality model outputting that the input triple is ungrammatical. Embodiments of the present invention can be used in a variety of machine learning and artificial intelligence applications, including but not limited to several anticipated use cases in material informatics, data security, data extraction, and medical/healthcare, for example, for supporting decision making or optimizing and calibrating of extracted chemical compounds from libraries of textbooks and publications.
