Demo – Paper 474
This demonstration presents Clover Quiz, a turn-based multiplayer trivia game for Android devices with more than 200K multiple choice questions (in English and Spanish) about different domains generated out of DBpedia. Instead of live queries, questions are created off-line through a data extraction pipeline and a versatile template-based mechanism. A back-end server manages the question set and the associated images, while a mobile app has been developed and released in Google Play on March 2017 under the names `Clover Quiz' in English and `Trebial' in Spanish. The game is available free of charge and has been dowloaded by more than 5K users at the time of this writing. During this period, more than 609K questions have been posed, and the overall rating of the game is 4.3 out of 5.0. Clover Quiz thus demonstrates the advantages of semantic technologies for collecting data and automating the generation of multiple choice questions in a scalable way.
