A tarefa de Correção Automática de Redação tem despertado crescente interesse na área de processamento de texto em português. Entre os conjuntos de dados disponíveis, destaca-se um corpus de redações narrativas produzidas por alunos do 5º ao 9º ano do ensino fundamental no Brasil. Essas redações são avaliadas segundo quatro competências: registro formal, coerência temática, estrutura retórica narrativa e coesão...
Creating engaging narratives from visual data is crucial for automated digital media consumption, assistive technologies, and interactive entertainment. This survey covers methodologies used in the generation of these narratives, focusing on their principles, strengths, and limitations. The survey also covers tasks related to automatic story generation, such as image and video captioning, and Visual Question An...
A avaliação da inteligibilidade de textos e a sua classificação por níveis de complexidade é essencial para o ensino de língua e para indústrias relacionadas com a linguagem que dependem de uma comunicação eficaz. O Quadro Europeu Comum de Referência para as Línguas (CEFR) é uma referência amplamente reconhecida para a classificação dos níveis de proficiência linguística. Este quadro pode ser utilizado não apen...
The iRead4Skills project aims to enhance adult literacy and essential skills by merging technology and culture. It addresses the needs of adult learners, particularly those with low literacy skills, by providing an intelligent system that evaluates text complexity and suggests readings suited to individual levels. This open-access system supports multilingual environments, offering resources in languages like P...
From the perspective of a dialog system, the identification of the intention behind the segments in a dialog is important, as it provides cues regarding the information present in the segments and how they should be interpreted. The ISO 24617-2 standard for dialog act annotation defines a hierarchically organized set of general-purpose communicative functions that correspond to different intentions that are rel...

Estamos envolvidos em um ambiente repleto de sons ao nosso redor. Estudar e analisar os impactos que a prática musical causa e mostrar matematicamente que esta prática pode proporcionar efeitos cognitivos significativos no cérebro humano são as principais motivações desta tese. Em mais detalhes, o objetivo desta tese foi desenvolver uma metodologia capaz de caracterizar os padrões de ativações corticais gerados...

No. of bitstreams: 0 Previous issue date: 2020-03-25; Fundação para a Ciência e a Tecnologia; Ti foams are attractive for orthopaedic applications due to reduced Young's modulus and ability of bone in-growth. However, poor corrosion behaviour and lack of bioactivity are yet to be overcome. In the present work, highly porous Ti samples were processed by pow...
Resources such as FrameNet, which provide sets of semantic frame definitions and annotated textual data that maps into the evoked frames, are important for several NLP tasks. However, they are expensive to build and, consequently, are unavailable for many languages and domains. Thus, approaches able to induce semantic frames in an unsupervised manner are highly valuable. In this paper we approach that task from...
