domain specific knowledge representation and inference engine for an intelligent tutoring system
Knowledge Based Systems, 2013Co-Authors: Miguel Arevalilloherraez, David Arnau, Luis MarcogimenezAbstract:One of the most challenging steps in learning algebra is the translation of word problems into Symbolic Notation. This paper describes an Intelligent Tutoring System (ITS) that focuses on this stage of the problem solving process. On the one hand, a domain specific inference engine and a knowledge representation mechanism are proposed. These are based on a description language based on hypergraphs, and the idea of using conceptual schemes to represent the student's knowledge. As a result, the system is able to simultaneously: (a) represent all potential algebraic solutions to a given word problem; (b) keep track of the student's actions; (c) univocally determine the current state of the resolution process; (d) build a student model; and (e) provide adaptive automatic remediation. On the other hand, the Graphical User Interface (GUI) has been designed to force the student to follow the sequence of steps described in the Cartesian method. The ITS has been evaluated in an educational environment. The results show significant gains for the experimental group and hence support the use of the ITS in practice.

melodic sound enhances visual awareness of congruent musical notes but only if you can read music
Proceedings of the National Academy of Sciences of the United States of America, 2015Co-Authors: Minyoung Lee, Randolph Blake, Su Jin Kim, Chaiyoun KimAbstract:Predictive influences of auditory information on resolution of visual competition were investigated using music, whose visual Symbolic Notation is familiar only to those with musical training. Results from two experiments using different experimental paradigms revealed that melodic congruence between what is seen and what is heard impacts perceptual dynamics during binocular rivalry. This bisensory interaction was observed only when the musical score was perceptually dominant, not when it was suppressed from awareness, and it was observed only in people who could read music. Results from two ancillary experiments showed that this effect of congruence cannot be explained by differential patterns of eye movements or by differential response sluggishness associated with congruent score/melody combinations. Taken together, these results demonstrate robust audiovisual interaction based on high-level, Symbolic representations and its predictive influence on perceptual dynamics during binocular rivalry.
