Um Método para a Utilização de Ontologias na Indexação Automática

The indexing process aims to represent synthetically the informational content of documents by a set of terms whose meanings indicate the themes or subjects treated by them. With the emergence of the Web, research in automatic indexing received major boost with the necessity of retrieving documents from this huge collection. The traditional indexing languages, used to translate the thematic content of documents in standardized terms, always proved efficient in manual indexing. Ontologies open new perspectives for research in automatic indexing, offering a computer-process able language restricted to a particular domain. The use of ontologies in the automatic indexing process allows using a specific domain language and a logical and conceptual framework to make inferences, and whose relations allow an expansion of the terms extracted directly from the text of the document. This paper presents techniques for the construction and use of ontologies in the automatic indexing process. We conclude that the use of ontologies in the indexing process allows to add not only new feature to the indexing process, but also allows us to think in new and advanced features in an information retrieval system.

Segurança na América Latina: cenários e perspectivas

In the post Cold War period, in the security field, has increased the mechanisms of cooperation and coordination among the Latin American states, in the context of so called confidence-building measures. These arrangements presented as important and efficient tools of political-strategic articulation and assist in the maintenance of peace in the region. The paper presents some considerations about the current scenario in terms of security and defense in Latin America. Initially, presents concepts of security and defense and perceptions of threats by the states.

Por que você não vai para Paris?

Coloquei minhas tralhas no bagageiro de cima e me acomodei na cadeira, depois de semanas correndo para terminar um artigo e me preparar para essa viagem. Olhei em volta fazendo um rápido reconhecimento, e relaxei na cabine do avião da El Al que me levaria direto de Guarulhos a Lod. Foi aí que escutei meu pai, com a voz tão sonora como se de fato estivesse lá: "Mas Guga, por que você não vai para Paris?".

Formação do professor para o uso de tecnologia assistiva

The specialized teachers' training to work in multifunctional resource classrooms still has to reach a satisfactory level. These teachers are expected to keep a set of resources and devices used to teach a wide range of students with different disabilities. That fact leads to reflection by the academic community. Thus what specific content should such training address? This paper aims to analyze the set of resources and equipment in a classroom and infer the teaching knowledge underlying their use. The analysis was conducted by classifying 63 resources and equipment items, which led to three categories: 1) set of materials that do not require academic knowledge; 2) set of materials that require academic knowledge related to any training course for teachers; 3) set of materials that require specific academic knowledge on working with students with disabilities. It concluded that around 36% of the resources do not require academic knowledge to be used; 35% of these resources and equipment require some academic knowledge to be properly handled, and around 29% of these resources and equipment require specific academic knowledge of their content. For instance, a specific training of those resources is necessary for acting with students with severe communication disorders, multiple disabilities and visual impairment or deafness.

Exposição neonatal a drogas ototóxicas e possíveis alterações auditivas

Introduction: Scientific evidence indicates that neonatal exposure to ototoxic drugs cause hearing loss in newborns. Objective: To characterize the use of ototoxic antibiotics in newborns (NB), treated in the Neonatal Intensive Care Unit (NICU) and evaluate possible hearing modifications. Methods: A descriptive cross-sectional quantitative approach, using data from medical records of infants who were at some time in the NICU and used antibiotics, including ototoxic, from January to June 2004 as much as 2010, and the data were compared and analyzed. Parents/guardians of infants born in 2004 were contacted and applied a questionnaire containing questions about the children’s hearing. These children were submitted to audiological evaluation. Results: There was significant reduction in the time of use, the amount of antibiotics prescribed to newborns and Vancomycin prescription in 2010 compared to 2004. The hearing tests of 13 born in 2004 showed: sensorineural hearing loss in only 2 (one with moderate hearing loss and descending configuration in pure tone audiometry and the other with bilateral cochlear impairment); audiometric thresholds within the normal range in 11 patients, and the presence of otoacoustic emissions in 9. In Evoked Auditory Brainstem Response (ABR) no changes were observed. Conclusion: The reduction in the time of use, the amount and types of antibiotics observed may be related to the adoption of a Protocol in 2008, by the service. In contrast, auditory alterations may be related to a neonatal exposure to antibiotics in 2004.

Concepções de 'palavra' em escolas de educação infantil

We searched for which conceptions twenty-three Kinden garden teachers would have of “word”, as well as for “echoes” from these conceptions in their 4-6 years old pupils. Essentially all the teachers showed a graphic and semantic conception of “word”. “Echoes” from these conception were detected in part of their pupils. The other part of children showed a conception in which could be detected enunciative, pragmatic and discursive aspects of language. Conception of teachers indicates ruptures between their pedagogic activities with literacy and their pedagogic activities with language unities such as word. These ruptures, however, not necessarily were made by part of children, who seems integrate language and literacy.

A representação na Arquivística contemporânea

The arrangement and description of archival materials are the nuclear processes of Archival Science that share a common purpose: to represent the archival knowledge. This representation is fundamentally based on the application of the principle of provenance and on the concept of fonds. This paper aims to discuss de archival description facing the changes and ideas of an archival postmodern approach that proposes the concept of fonds and the principle of provenance as conceptual abstraction rather than a physical entity in the representation process. In that sense, it is presented here the theoretical perspectives of Canadian and Australian studies, discussing the theoretical basis of Modern Archival Science, facing the dynamic reality of contemporary record creation.

A perspectiva metodológica da resolução de problemas: um estudo sobre enunciados de situações matemáticas na EJA

In this paper we discuss the importance of a methodological perspective of solving problems as a sustaining process of teaching mathematics situated on the perspective of concept formation. Organizing a significant didactic situation for students imposes the need to study the interaction between them and the teacher and between them and their mathematical knowledge, learning environment in which the mere transmission of content gives way to contextualization, to historicizing and handling of topics from intuitive and everyday situations for the student. Thus, we understand mathematics as a fundamental language for the creation of theoretical thinking as a whole. We made use of documental analysis and classroom situations aiming at the use of instructional procedure related to the resolution of problems with the purpose of overcoming some representations about the process of teaching and learning mathematics which is strongly marked by imitative-repetitive algorithmic procedures. Considering mathematics as an investigation discipline, we point out renewal prospects for the curricula of this discipline, which are concrete in the movement of cultural action of the school itself as the cell generating discussion.

A importância da arte no sistema filosófico de Hegel

What does it mean to say that Hegel is an idealist philosopher? Such determination is appropriate? If appeals Hegel to speculative approach, then how to understand their idealism? These questions guide the role of art in Hegel's philosophical system identifying a philosophy deeply committed and involved in its determination that takes place in the history or thought. If art is the moment of sensible intuition that Hegel considers carefully, then it is possible to conclude that the idealist perspective attributed to Hegel must be taken with reservations or its own idealism needs to be seen beyond all subjective levy.
