Diagnosis of learner dropout based on learning styles for online distance learning

The amount of data generated by computer systems in Online Distance Learning (ODL) contains rich information. One example of this information we define as the Learner Learning Trail (LLT), which is the sequence of interactions between the students and the virtual environment. Another example is the Learner Learning Style (LLS), which is associated with the [...]

O uso de simuladores no auxílio do ensino-aprendizagem na Enfermagem

Este estudo objetivou verificar a perspectiva dos acadêmicos do curso de enfermagem acerca do uso de simuladores no auxílio do ensino-aprendizagem. Trata-se de um estudo transversal, exploratório, descritivo com abordagem quantitativa. A coleta de dados foi realizada através de um questionário validado, aplicado a partir da plataforma Google Forms. A amostra foi composta por 27 [...]

Enhancing Brazilian Portuguese Textual Entailment Recognition with a Hybrid Approach

Previous work on textual entailment has not fully exploited aspects of deep linguistic relations, which have been shown as containing important information for entailment identification. In this study, we present a new method to compute semantic textual similarity between two sentences. Our proposal relies on the integration of a set of deep linguistic relations, lexical [...]

A Hospital Bed Allocation Hybrid Model Based on Situation Awareness

Bed management is an important area of planning and control for hospitals, as it has the important role of maintaining the balance between patients from the emergency department, patients who have elective surgery or scheduled treatment, and patients who are discharged from the hospital, while maintaining high bed occupancy rates. Effective management of these resources [...]

Toward a Model for Personal Health Records Interoperability

Health information technology, applied to electronic health record (EHR), has evolved with the adoption of standards for defining patient health records. However, there are many standards for defining such data, hindering communication between different healthcare providers. Even with adopted standards, patients often need to repeatedly provide their health information when they are taken care of [...]

Um Sistema de Recomendação para Professores e Coordenadores de Curso utilizando Predição de Reprovação na Educação a Distância

Este artigo propõe um modelo de Sistema de Recomendação Educacional baseado na predição de reprovação de aprendizes em disciplinas de Educação a Distância. Propõe-se o RECD, um modelo de Sistema de Recomendação Educacional para coordenadores de curso e professores, que recebe de um algum sistema de predição, dentre eles o MD-PREAD, dados estatísticos quanto à [...]

Ontology-based information extraction for juridical events with case studies in Brazilian legal realm

The number of available legal documents has presented an enormous growth in recent years, and the digital processing of such materials is prompting the necessity of systems that support the automatic relevant information extraction. This work presents a system for ontology-based information extraction from natural language texts, able to identify a set of legal events. [...]

A food allergy risk detection model based on situation awareness

Advances in ubiquitous computing are enabling the emergence of opportunities in many areas; among them we highlight the health-related applications. In this area, there is a trend toward developing many applications that enable care wherever you are and whenever you need, called ubiquitous healthcare. A detailed survey of existing and proposed models has shown that [...]

Assistive Robotics: Adaptive Multimodal Interaction Improving People with Communication Disorders

A significant portion of the Brazilian population consists of people with hearing or visual impairment. Multimodal interaction systems do not suit the needs of a mixed audience, since they are designed for a specific user profile. We propose a model for a Multimodal Human Computer Interaction System (MMHCI) based on services, embedded on an assistive [...]

RecSim: A Model for Learning Objects Recommendation using Similarity of Sessions

A learning object (LO) is any entity or resource that can be used in computer-aided learning. This can take the form of text, multimedia content, presentations, programs or any other type of digital content, generally made available through web portals or distance learning systems. The LOs consulted by a student while accessing such portals are [...]
