1. Recuperação de vídeos comprimidos por conteúdo / Content-based retrieval of compressed videos
Recent advances in the technology have enabled the increase of the availability of video data, creating large digital video collections. This has spurred great interest in systems that are able to manage those data in a efficient way. Making efficient use of video information requires the development of powerful tools to extract high-level semantics from low

2. Um estudo sobre a Teoria da Predição aplicada à análise semântica de Linguagens Naturais. / A study on the Theory of Prediction applied to the semantical analysis of Natural Languages.
In this work, computer learning is studied as a problem of induction. Starting with the proposal of an architecture for a system of semantic analisys of Natural Languages, the two modules necessary for its construction were built and tested independently: a pre-processor, capable of mapping the contents of texts to a representation in which the semantics of

3. Abordagem semântica aplicada ao gerenciamento de dados em redes de sensores sem fio. / Semantic approach to the management of data from the wireless sensor network.
In the recent years, the volume of data available from wireless sensor networks (WSN) has increased considerably. WSN is a technology that allows the development of applications in various types of environments (pervasives, Ubiquitous, controlled and with difficult access environment), doing that concern for content managing is greater. Among the proposals,

4. ClassificaÃÃo supervisionada usando dados simbÃlicos de semÃntica modal
The Symbolic Data Analysis (SDA) is a domain in the area of automatic discovery of knowledge that it aims at to develop methods for described data for variables that can assume as value lists of categories, intervals or distributions of probability. These variables allow to take in account the variability and/or uncertainty present in the data. This work pre

5. Fluid Web and digital content components : from the document-centric view to the content-centric view / Fluid Web e componentes de conteudo digital : da visão centrada em documentos para a visão centrada em conteudo
The Web is evolving from a space for publicationj consumption of documents to an environment for collaborative work, where digital content can traveI and be replicated, adapted, decomposed, fusioned and transformed. We call this the Fluid Web perspective. This view requires a thorough revision of the typical document-oriented approach that permeates conten

6. Anatomy of word and sentence meaning
Reading and listening involve complex psychological processes that recruit many brain areas. The anatomy of processing English words has been studied by a variety of imaging methods. Although there is widespread agreement on the general anatomical areas involved in comprehending words, there are still disputes about the computations that go on in these
