  Generating syntactically and semantically valid and relevant questions from
paragraphs is useful with many applications. Manual generation is a
labour-intensive task, as it requires the reading, parsing and understanding of
long passages of text. A number of question generation models based on
sequence-to-sequence techniques have recently been proposed. Most of them
generate questions from sentences only, and none of them is publicly available
as an easy-to-use service. In this paper, we demonstrate ParaQG, a Web-based
system for generating questions from sentences and paragraphs. ParaQG
incorporates a number of novel functionalities to make the question generation
process user-friendly. It provides an interactive interface for a user to
select answers with visual insights on generation of questions. It also employs
various faceted views to group similar questions as well as filtering
techniques to eliminate unanswerable questions
