What is the current status of systems which can answer questions framed from a given text article?
Question Generation (QG)  and Question Answering (QA)  are two different things. In terms of question answering systems (QA systems), I suggest looking at the Ephyra Question Answering System (OpenEphyra) .
As part of my Meta-Guide.com project, I’m currently running an experiment on Twitter, parsing travel questions off the Twitter firehose and running them into two different conversational agents (chatbots) at @VagaBot  and @TwavelAdvisor . Over the past year I have accumulated more than 36,000 unique travel questions.
