ClausIE: Clause-Based Open Information Extraction

Introduction

ClausIE is an open information extractor; it identifies and extracts relations and their arguments in natural language text. ClausIE first detects "useful" pieces of information expressed in a sentence, and then represents this information in terms of one or more extractions. The representation of these extractions can be flexibly customized to the underlying application (e.g., binary or n-ary propositions).

For more information, please refer to the ClausIE tutorial or to our WWW paper.
