“…Our approach was applied in a real usage scenario by including the metamodel, matrix and triplification process. This scenario focused on the implementation of computational environments according to the enactive systems concept [7]. This paper goes further in the computational and technological aspects.…”

“…Previous contributions presented a hypothetical theoretical scenario, unlike our current study, which includes a practical application involving robotics and education. This empirical application was previously presented at [7], which focused on providing a human-computer interaction perspective of students and robot interactions in an educational setting. Caceffo et al [7] included a limited version of our implementation (using matrix) as well as it was not integrated with other models, such as RDF.…”

“…In addition, our full proposal of soft ontology representation and triplification was not applied to a case study before. The study in [7] focused on fully describing the workshop conducted and the behavior of the children in the under study scenario. Our presented paper contributed to an extended and deeper analysis on the matrix of probabilities in this case study.…”

Soft ontologies aim to provide more flexible knowledge representations as compared with hierarchy-based ontology models. Soft ontologies can restructure itself according to the necessities of an interaction context. This is especially desirable in systems that need to deal with dynamic domains and situations with a high degree of uncertainty. However, the definition of soft ontologies is a challenging task due to the lack of generic and well defined components. In addition, such definition may suffer from problems with interoperability and integration with other models. We argue that soft ontologies should coexist with other models in an interoperable framework. In this paper, we propose and formalize a metamodel to provide adequate conciliation among various ontology representation approaches. We develop soft ontologies based on matrices of probabilities and apply a triplification process in which concepts are represented as fuzzy RDF statements. Our proposal was evaluated in a case study in an educational context, which uses a soft ontology to express a repertoire of actions in an mBot robot. The results indicate the feasibility of our fuzzy RDF approach to represent soft ontologies and the use of the metamodel to support interoperability in heterogeneous ontology networks.

“…a constructionist robot-based learning environment was created for kindergarten children, ages 4 to 5 years old, who have not yet mastered the use of written language. The objective of the activity was for the children to interact, as a group, with computational technology that is enriched with sensors and actuators (Caceffo et al, 2019). This activity was developed based on the Little Red Riding Hood story, adapted to a situation closer to the children's daily lives, with the goal of playfully addressing aspects of interaction and collaboration among them.…”

Constructionism has different meanings for what the learner is constructing, a concrete object or an idea, and whether this construction is done through the use of digital technology. In the embodied-based environment created in this study, children carry out or "construct" a series of actions, a performance, which allows them to solve the task of directing an already programmed robot to a particular target. The activity was based on an adaptation of the Little Red Riding Hood narrative. Children played the role of rangers (instead of hunters) who had to coordinate their actions in order to help a robot (an mBot characterized as a Robot-Wolf) find Grandma's laboratory, so she could fix its GPS. The children wore boots, which were used to interact with the Robot-Wolf. The main question we addressed was how to create this embodiedbased environment for kindergarten children, and how to identify the actions children performed and the concepts they used in this construction. The research was based on the Socially-Aware Design, and the study was conducted in a school setting for kindergarten students. 26 children (11F, 15 M), between 4 and 5 years old, participated in this study. The children's activities were recorded and analysed using the Grounded Theory methodology. The results show
