Extração automática de relações semânticas a partir de textos escritos em português do Brasil
(Universidade Federal de São Carlos, 2013-07-11)
Information extraction (IE) is one of the many applications in Natural Language Processing (NLP); it focuses on processing texts in order to retrieve specific information about a certain entity or concept. One of its ...
Análise da escalabilidade de aplicações em computadores multicore
(Universidade Federal de São Carlos, 2013-06-14)
Multicore processors allow applications to explore thread-level parallelism in order to enable improvements on the elapsed time. The sharing of the memory subsystem and the discrepancy between the speeds of processors and ...

Algoritmo para a extração incremental de sequências relevantes com janelamento e pós-processamento aplicado a dados hidrográficos
(Universidade Federal de São Carlos, 2013-06-07)
The mining of sequential patterns in data from environmental sensors is a challenging task: the data may show noise and may also contain sparse patterns that are difficult to detect. The knowledge extracted from environmental ...
Geração de dados espaciais vagos baseada em modelos exatos
(Universidade Federal de São Carlos, 2013-05-29)
Geographic information systems with the aid of spatial databases store and manage crisp spatial data (or exact spatial data), whose shapes (boundaries) are well defined and have a precise location in space. However, several ...
Análise de escalabilidade de aplicações Hadoop/Mapreduce por meio de simulação
(Universidade Federal de São Carlos, 2013-02-04)
During the last years we have witnessed a significant growing in the amount of data processed in a daily basis by companies, universities, and other institutions. Many use cases report processing of data volumes of petabytes ...
Reconhecimento de gestos da Língua Brasileira de Sinais através de máquinas de vetores de suporte e campos aleatórios condicionais ocultos
(Universidade Federal de São Carlos, 2013-05-24)
This work investigates the use of Support Vector Machines and Hidden Conditional Random Fields in the recognition of signs from the Brazilian Sign Language (Língua Brasileira de Sinais, Libras). Employing basic concepts ...
Conversing learning: applying the wisdom of crowds to assist never ending learning tasks
(Universidade Federal de São Carlos, 2013-09-21)
In Machine Learning systems we often apply techniques are often applied to learn about real world problems behavior from data. Traditionally, such data comes from instances of datasets (that represents the target problem) ...
