** DEPRECATED! ** Please see https://github.com/dair-iitd/OpenIE-standalone, which has combined multiple projects into a single project and maintains the latest version of Open IE (Open IE 5). It is based on another repository https://github.com/allenai/openie-standalone, which has an older version of Open IE.
The chunked extractors project is a collection of three extractors.
- ReVerb--an extractor for verb-mediated relations (
Sally sells sea shells).
- Relnoun--an extractor for noun-mediate relation (
United States president Barack Obama).
- Nesty--an extractor for nested relations (
Some people say that we never landed on the moon).
This project provides a common interface to the three extractors by using the nlptools project for chunking and lemmatization.
