Tradução automática estatística baseada em sintaxe e linguagens de árvores
(Universidade Federal de São Carlos, 2012-06-19) Beck, Daniel Emilio; Caseli, Helena de Medeiros; https://lattes.cnpq.br/6608582057810385; https://lattes.cnpq.br/0876169547835331
Machine Translation (MT) is one of the classic Natural Language Processing (NLP) applications. The state-of-the-art in MT is represented by statistical methods that aim to learn all necessary linguistic knowledge automatically through large collections of texts (corpora). However, while the quality of statistical MT systems had improved, nowadays these advances are not significant. For this reason, research in the area have sought to involve more explicit linguistic knowledge in these systems. One issue that purely statistical MT systems have is the lack of correct treatment of syntactic phenomena. Thus, one of the research directions when trying to incorporate linguistic knowledge in those systems is through the addition of syntactic rules. To accomplish this, many methods and formalisms with this goal in mind are studied. This text presents the investigation of methods which aim to advance the state-of-the-art in statistical MT through models that consider syntactic information. The methods and formalisms studied are those used to deal with tree languages, mainly Tree Substitution Grammars (TSGs) and Tree-to-String (TTS) Transducers. From this work, a greater understanding was obtained about the studied formalisms and their behavior when used in NLP applications.
A Educação a Distância e a formação de professores na UFSCar : a autoridade, a autonomia e o corpo mediados pelas Tecnologias da Informação e Comunicação
(Universidade Federal de São Carlos, 2012-06-19) Verdan, Kelly Cristiane da Silva; Zuin, Antônio Álvaro Soares; https://lattes.cnpq.br/5543562307373287; https://lattes.cnpq.br/9642286425653813
This present work aims to investigate the implementation of distance education as a mode of education with to formation in pedagogy at the University Federal of San Carlos, noting the authority and the body present or absent in pedagogical relationships mediated by Information Technology and Communication. Therefore a study was conducted on Culture, Technology and Education to draw a picture about the prevalence of technology in everyday society, then addressing public policies for the implementation of distance learning in Brazil, highlighting how this type of education occurred on UFSCar. After that, through interviews and questionnaires were analyzed issues mentioned above, through the theoretical framework of critical theory.
