Pistas en lenguaje natural en jueces en línea

Abstract

Online judges are used more and more for curricular learning, so students have contact with this kind of sys- tem earlier during their learning process. Unfortuna- tely, online judges suffer a persistent lack of feedback, which can cause frustration in novice users. In ¡Acep- ta el reto!, an online judge with problems in Spanish, a new system of hints has been incorporated in order to provide feedback to users who make some com- mon mistakes. Hints are provided in natural language and, although it does not use advanced techniques, the system can be very effective, especially for those pro- blems with many submissions.
