OK I get you and yes this makes pefect sense.

> Does the model load on every call to the CLI?

... yes... which I realize is far from ideal. The issue with this as well 
is that it will load on every document AFAIK so this is a major limitation of 
the approach as it currently sits.

ByteArrayOutputStream will hold all of the results in memory. It may be 
useful to create a temporary file and reference it as a FileOutputStream, which 
will have a fixed memory buffer before writing to disk. Just trying to work 
through the possible avenues where memory requirements can be managed. It may 
be useful to work through in a debugger to identity the large memory 
requirement and where that can be lowered, as hopefully the CLI can still be 
used on small machines after this pull request. Does the model load on every 
call to the CLI?

Writing to a file instead of ByteArrayOutputStream may alleviate some of

[GitHub] any23 pull request #34: ANY23-304 Add extractor for OpenIE

ANY23-304 Add extractor for OpenIE

Hi Folks,
This issue is a rework of #33 which takes on board @ansell 's comments to 
add the new extractor as a separate module as oppose to inside of core. 
There are a number of classes which are cleaned up for JDK1.8 compliance.
In addition, this new functionality augments the default configuration by 
introducing a threshold for OpenIE extractions of 0.5. Anything below this 
value is not converted into triples.
I run a test extraction on a reasonably testing Webpage from the 
[PO.DAAC](http://podaac.jpl.nasa.gov/aquarius) but right now i am not asserting 
anything.
As far as I can see this is working pretty well but some community review 
would go a long way.
