This article focuses on the development of Natural Language Processing (NLP) tools for Computer Assisted Language Learning (CALL). After identifying the inherent limitations of NLP-free tools, we describe the general framework of Mirto, an NLP-based authoring platform under construction in our laboratory, and organized into four distinct layers: functions, scripts, activities and scenarios. Thr...

A data mining system designed to associate previous solar flares with sunspot groups using databases from Nobeyama Radioheliograph and the National Geophysical Data Center, and associated data used for training verification, and comparison of several Neural Networks topologies which can be used with an automated solar activity prediction system in the future. The data mining system manages to a...

Enjoyment and experience-based activities are important in today’s society. The purpose of this paper is to explore and better understand how experiences can be enhanced using IS in such experience-based enterprises. The research is based on a case study conducted in collaboration with a Swedish regional museum, where a location-aware auditory museum application for experience enhancement is be...

Traditionally, instructional design has adopted a behaviourist theoretical perspective, but with the influence of other major learning theories and the latest technological advances, cognitivist and constructivist perspectives have gained more predominance. Whichever approach we choose, if we want to take advantage of the web potential as an educational tool, we need to apply the basic componen...
