Hi!
I'd just like to let you guys "officially" know about my work so
far at developing a "minimally usable" opensource question-answering
pipeline BlanQA:
http://brmlab.cz/project/brmson
You may also find my survey of the current OSS landscape in QA
interesting, at the same page
(
http://brmlab.cz/project/brmson#knowledge_base). Let me know if
I missed anything important!
I have summarized my work so far and the (unfortunately difficult)
way forward at:
http://log.or.cz/?p=317
I'll be happy to collaborate with others on this - after all, it's
open source. :-)
Happy hacking,
Petr "Pasky" Baudis
