1. Implementação computacional e verificação de ontologias para a modelagem da confiança em transações na web
O avanço da World Wide Web tem mudado a forma como os negócios são conduzidos entre as organizações. A Web Semântica é o próximo passo na evolução da web. Ela trata de agregar significado semântico ao seu conteúdo, tornando-o mais acessível a máquinas. Dentre os componentes da Web Semântica encontram-se as ontologias, que são representações

2. A construção de informações documentárias: aportes da linguística documentária, da terminologia e das ontologias / Documentary information: contributions of ontology, terminology and documentary linguistic.
Investigates theoretical and practical interfaces between terminology, philosophical ontology, computational ontology and documentary linguistics and the subsidies that they offer for the construction of documentary information. It was established as specific objectives, the analysis of the production, development, implementation and use of ontologies based

3. Aspectos ontológicos da web-semântica: investigação para a utilização do histórico da web-semântica como contribuição para a melhoria da navegação na web
This study presents a framework for considering the problems related to web-semantics and logic as applied to the cyberspace computational context, its agents and engines for searching purposes. Highlighting some historical issues concerning the philosophy of language and logic, the theoretical background contemplates the problems and methods tackled by webs

4. Uma arquitetura orientada a agentes para gerenciamento, busca e recuperação de artefatos científicos
A Computação Científica é uma área multidisclipinar que extrapola o uso do computador como simples máquina onde pesquisadores escrevem textos, apresentações ou guardam resultados de experimentos e análises. Com a evolução das pesquisas, e o uso cada vez maior de recursos computacionais aplicados aos experimentos e simulações realizados pelos gru

5. A service-oriented infrastructure for ecological niche modelling. / Uma infraestrutura orientada a serviços para a modelagem de nicho ecológico.
Ecological niche modelling combines environmental data and information about the occurrence of a species to obtain models to describe its probabilistic distribution in a region. Computational algorithms generate models based on the hypothesis that, if a species was found under the conditions which define its niche, then it may survive in any place which offe

6. Algoritmos para Interoperabilidade entre Ontologias / ALGORITHMS FOR ONTOLOGIES INTEROPERABILIT
Nowadays the interest for the theme ontologies has steadily increased, as it aims at to capture consensual knowledge between people and applications, allowing reusing and sharing information. With this purpose, mechanisms are demanded to guarantee semantic interoperability, that is, the identification and compatibility of information. The present study propo

7. GeOntoQuery - um mecanismo de busca em bancos de dados geográficos baseado em ontologias
Geographic Information System (GIS) are computational tools used to capture, store, consult, manipulate, analyze and print geo-referenced data. A GIS is a multi-disciplinary system that can be used by different communities of users, each one having their own interest and knowledge. This way, different knowledge views about the same reality need to be combine

8. WORKFLOW PARA BIOINFORMÁTICA / WORKFLOW FOR BIOINFORMATICS
Genome projects usually start with a sequencing phase, where experimental data, usually DNA sequences, is generated, without any biological interpretation. DNA sequences have codes which are responsible for the production of protein and RNA sequences, while protein sequences participate in all biological phenomena, such as cell replication, energy production

9. Contributions to an Anthropological Approach to the Cultural Adaptation of Migrant Agents
This thesis proposes the use of Cultural Anthropology as a source of inspiration for solutions to the problem of adaptation of autonomous, intelligent, computational agents that migrate to societies of agents with distinctive features from the ones of the society where those agents were originally conceived. This has implications for interoperation of dispar

10. DIAN: A Novel Algorithm for Genome Ontological Classification
Faced with the determination of many completely sequenced genomes, computational biology is now faced with the challenge of interpreting the significance of these data sets. A multiplicity of data-related problems impedes this goal: Biological annotations associated with raw data are often not normalized, and the data themselves are often poorly interrelated

11. PSORTdb: a protein subcellular localization database for bacteria
Information about bacterial subcellular localization (SCL) is important for protein function prediction and identification of suitable drug/vaccine/diagnostic targets. PSORTdb (http://db.psort.org/) is a web-accessible database of SCL for bacteria that contains both information determined through laboratory experimentation and computational predictions. The

12. Unraveling the Relationship between Grapes and Health1–4
As described in this Supplement and elsewhere, consumption of grapes or grape products has been associated with various health benefits. Resveratrol is a unique component of grapes. Following our report on potential cancer chemopreventive activity, thousands of studies have been performed to characterize the mode of action of this substance. Nonetheless, sco
