Modify OpenIE output into the TTL format supported by AutoIndex

[Suganya31]

Currently the open IE extractor returns a Jena model like this for the input "Obama was born in the USA."

@Prefix : http://example.org/ .
@Prefix rdf: http://www.w3.org/1999/02/22-rdf-syntax-ns# .

:Obama :be :bear ;
http://example.org/be%20bear%20in
:USA .

@RicardoUsbeck Hi Ricardo, I was able to modify the Open-IE output to the following
FINALIE.txt

When I stored them in the DB they are displayed as shown in the following file.

When I checked FOX, they also use RDFDataMgr.write(StringWriter, graph, TTL);
I assume this way of writing models using RDFDataMgr.write does not add label to the predicate. Please tell me your view.

It is definitely better but not as usable as FOX output. We need to combine that with a Named Entity Disambiguation Approach such as AGDISTIS for entities (https://github.com/dice-group/AGDISTIS) and NLIWOD for properties (https://github.com/dice-group/NLIWOD/tree/master/qa.annotation/src/main/java/org/aksw/qa/annotation/index) on top of OpenIE. In the end, the output should look like the following given (Obama, born, USA):

@prefix dbo:   <http://dbpedia.org/ontology/> .
@prefix dbr:   <http://dbpedia.org/resource/> .
@prefix ex: <http://example.org/> .

dbr:USA <http://www.w3.org/2000/01/rdf-schema#label>  "USA" .
dbo:born <http://www.w3.org/2000/01/rdf-schema#label>  "born" .
dbr:Obama <http://www.w3.org/2000/01/rdf-schema#label>  "Obama" .
dbr:Obama dbo:born dbr:USA.

However, this is a task for @hjshah142 for next semester.
