Presuming this is stub code right now that will eventually send results to
the ExtractorResult.
> Add extractor for OpenIE
> ------------------------
>
> Key: ANY23-304
> URL: https://issues.apache.org/jira/browse/ANY23-304
> Project: Apache Any23
> Issue Type: Bug
> Components: core, extractors
> Reporter: Lewis John McGibbney
> Assignee: Lewis John McGibbney
> Fix For: 2.1
>
>
> I'm going to start work on an extractor which uses the OpenIE library
> https://github.com/allenai/openie-standalone
> This will provide us with the ability to execute structured extractions from
> unstructured content essentially taking Any23 in a new direction.
