Pointers for building Jacana-based QA pipe?

[k0105]

Dear Dr. Yao,

I've been trying to use Jacana, but I'm confused how to set up a general-purpose QA pipeline with it. While I have been able to obtain all libraries for build.qa.xml and then compile jacana-qa.jar I'm not sure how to train my QA model. Is there any straightforward way to get a working prototype, ideally for a corpus like Wikipedia? Also: I'm still unsuccessful with build.freebase.xml, even though I have my own Freebase node. It says Could not load definitions from resource scala/tools/ant/antlib.xml. It could not be found. [...] Problem: failed to create task or type scalac Is it worthwhile to try to fix this?

I also don't quite understand how to proceed - java -jar jacana-qa.jar yields java -jar jacana-qa.jar Exception in thread "main" java.lang.ClassNotFoundException: edu.jhu.jacana.qa.AnswerFinder. Is that supposed to happen?

Any help would be greatly appreciated. Thanks in advance.

Best wishes,
Joe
