Adaptive Educational Systems (AES) make use of Artificial Intelligence techniques aiming at adapting themselves to the real needs of the student, and through such provide a personalized and individualized teaching. In order for this adaptation to be successful, it is important that the system knows the level of knowledge concerning the real cognitive state of the students. In this manner, this article...
Interaction modeling is a relevant activity during software development processes. Created relying on Petri Nets theory and aiming to represent discrete time events, Colored Petri Nets (CPNs) are a graphical formal language developed and widely employed for system modeling. While traditional CPNs only have elements with ordinary stylization and behaviors, in this article we explore the key ideas behind...
Dynamic adaptation of educational content has been an important research topic. Therefore, in order for it to run effectively, student models that properly describe and monitor the cognitive state of students are needed. In this sense, this paper presents a hybrid student model approach that combines ontologies and Bayesian Networks to identify the knowledge of each student based on their characteristics...
Multimedia capture and context awareness are two relevant subjects in ubiquitous computing research. While the former results in large amounts of digital media (e.g., video, audio, slides, text comments) being automatically produced, the latter offers the proper means to integrate and access such content. By merging the two concepts, users may benefit from tools that allow them to retrieve, view and...
