It's a little confusing to understand reference.conf and how to play with the options available to configure the processors.
I can't get the README instructions for spinning up a docker container to work.
On macOS High Sierra Version 10.13.1
2.8 GHz and 8 i7 cores (4 dedicated to the docker machine)
16GB memory (8 dedicated to docker-machine)
mac:Stargraph hobs$ nano docker-compose.yml
mac:Stargraph hobs$ docker-machine --version
docker-machine version 0.13.0, build 9ba6da9
mac:Stargraph hobs$ docker-compose --version
docker-compose version 1.17.1, build 6d101fb
mac:Stargraph hobs$ docker --version
Docker version 17.09.1-ce, build 19e2cf6All the required data/indices seem to be loaded:
mac:Stargraph hobs$ curl -XGET http://localhost:8917/_kb
["dbpedia-2016/entities","dbpedia-2016/facts","dbpedia-2016/relations","obama/entities","obama/facts","obama/relations"]And the server container seems to boot up without crashing...
mac:Stargraph hobs$ docker-compose up

* Closing connection 0The loading process can take quite a long time hence the user needs some kind of feedback if a query is issued while loader is still running.
Defaults on reference.conf relies on CoreNLP library as the annotator. It's not just a matter of flipping the configuration with OpenNLP (already available) because this will only avoid using the CoreNLP libraries at runtime while still being shipped with the whole platform.
Folks,
This is a great project and piqued my interest quite a bit. I've been trying to run the example query on the dbpedia dataset as specified in the Readme for this repo.
docker-compose up (with the specified yml file) works as expected and starts up the elasticsearch and stargraph containers.
However, when executing the example query of "who is the wife of Barack Obama?", elastic returns a nonodeavailableexception. I am guessing it's got something to do with the docker IP here but any pointers would be super helpful. Appreciate all your help.
Cheers,
Sri

All the subsystems that are sensitive to the language are able to handle multiple languages. We need to make sure we have enough test for each supported language mainly because each one requires a different set of data Resources.
This is because we still have to publish Indra artifacts on Maven Central.
Stargraph does not need to wait for ES to startup but sometimes users can have problems to start ES hence Stargraph will not be aware. Not sure if it's worth given that SG must clear return a useful message for the user instead of being in silence.
While we use HDT as our triple store we need to give instructions and documentation pointers on how to create a new HDT file.
Currently a lot of the architecture puzzle is put together wiring configuration with a few Java factories. To be able to deal with custom libraries and licenses it's suggested to have a plugin architecture to add/remove features on a post-install basis.
.. instead of use the public http://indra.lambda3.org
Indra and Wordnet are not public available from maven central yet.
While we're still porting from version 1 the rules are being improved continually. Most of the time is just a matter to explicit declare the capturing group in the Regular Expression.
We publish the code with OpenNLP but we still need to be flexible to switch to CoreNLP or any custom POS tagger implementation.
