Open Information Extraction (IE) is the task of extracting assertions from massive corpora without requiring a pre-specified vocabulary. [...] Key Method We implemented the constraints in the ReVerb Open IE system, which more than doubles the area under the precision-recall curve relative to previous extractors such as TextRunner and woepos. More than 30% of ReVerb's extractions are at precision 0.8 or higher---compared to virtually none for earlier systems. The paper concludes with a detailed analysis of…Expand
