Problem Statement/Motivation

What do we want?

Paraphrase data which is useful for various NLP tasks (QA, summarization, translation etc.)

How are paraphrases created?

By applying a set of grammatical operations (change voice, change tense, substitute phrase, etc.)

How do we provide (non-monetary) incentives to people to create paraphrase data for us?

By formulating it as a multi-player game for learning grammar

Why would people be interested in this

Learning grammar is an important aspect of learning a language

         
Students generally find it boring to learn grammar rules through textbook based exercises
Current methods and issues

Games

Learning aid (arrange words relative to each other to produce grammatically correct output)

A board game with instructions in a foreign language
Shortcoming: No multi-player game for creating paraphrase data while learning grammar
