A notification and recommender mobile app for educational online discussion: A design research approach

Abstract

This research presents an information system design theory (ISDT) to integrate a notification and recommendation system (NARS) into online discussion forums on mobile devices. The artifact is designed with respect to awareness and information overload as kernel theories. Furthermore, the design includes an intuitive way to improve the accuracy of short-text clustering used to extract semantic topics from posts. The paper describes a prototype of the design artifact, experiments to evaluate the proposed short-text clustering method, and a survey to evaluate the quality of the artifact prototype.
