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.

Given the exponential growth in the spread of the virus world wide web (Internet) and its increasing complexity, it is necessary to adopt more complex systems for the extraction of malware finger-prints (malware fingerprints - malicious software; is the name given to extracting unique information leading to identification of the virus, equivalent to humans, the fingerprint). The architecture and protocol proposed here aim to achieve more efficient fingerprints, using techniques that make a single fingerprint enough to compromise an entire group of viruses. This efficiency is given by the use of a hybrid approach of extracting fingerprints, taking into account the analysis of the code and the behavior of the sample, so called viruses. The main targets of this proposed system are Polymorphics and Metamorphics Malwares, given the difficulty in creating fingerprints that identify an entire family from these viruses. This difficulty is created by the use of techniques that have as their main objective compromise analysis by experts. The parameters chosen for the behavioral analysis are: File System; Records Windows; RAM Dump and API calls. As for the analysis of the code, the objective is to create, in binary virus, divisions in blocks, where it is possible to extract hashes. This technique considers the instruction there and its neighborhood, characterized as being accurate. In short, with this information is intended to predict and draw a profile of action of the virus and then create a fingerprint based on the degree of kinship between them (threshold), whose goal is to increase the ability to detect viruses that do not make part of the same family

Machine translation systems have been increasingly used for translation of large volumes of specialized texts. The efficiency of these systems depends directly on the implementation of strategies for controlling lexical use of source texts as a way to guarantee machine performance and, ultimately, human revision and post-edition work. This paper presents a brief history of application of machine translation, introduces the concept of lexicon and ambiguity and focuses on some of the lexical control strategies presently used, discussing their possible implications for the production and reading of specialized texts.

This paper analyzes how machine translation has changed the way translation is conceived and practiced in the information age. From a brief review of the early designs of machine translation programs, I discuss the changes implemented in the past decades in these systems to combine mechanical processing and the accessory work by the translator.

Identify opportunities for software parallelism is a task that takes a lot of human time, but once some code patterns for parallelism are identified, a software could quickly accomplish this task. Thus, automating this process brings many benefits such as saving time and reducing errors caused by the programmer [1]. This work aims at developing a software environment that identifies opportunities for parallelism in a source code written in C language, and generates a program with the same behavior, but with higher degree of parallelism, compatible with a graphics processor compatible with CUDA architecture.

Este trabalho tratou sobre o regime de progressão continuada, que foi implantado na rede pública de ensino do Estado de São Paulo em 1998, a partir da Deliberação do Conselho Estadual de Educação (CEE-SP) nº 09/1997, que pretendia uma reorganização escolar com a mudança do sistema seriado para a estruturação em ciclos.Criando assim novas formas de avaliação dos alunos e ainda, com a intenção de diminuir o fluxo da evasão escolar, abrir novas vagas, desonerar os cofres públicos, superar a fragmentação do currículo do ensino organizado em séries, entre outras demandas. Por meio de investigação qualitativa, levantamento bibliográfico e pesquisa documental,examinou-seo proposto com a implantação do regime de progressão continuada e dos ciclos no Estado de São Paulo e como ocorria a prática de promoção/aprovação automática dos alunos. Levantou-seos aspectos históricos e políticos relacionados a esta política pública educacional brasileira, indicando os inúmeros obstáculos enfrentados pelos professores e demais atores envolvidos nessa proposta, que se pretendeu progressista e includente, mas que, como podese perceber, uma vez que muitas das intenções estabelecidas na legislação não foram asseguradas, levou ao insucesso do regime de progressão continuada e da organização do ensino por ciclos no Estado Paulista, acarretando no Projeto de Lei nº 857/2015, que ainda se encontra em análise para posterior votação e indaga sobre a progressão continuada ter se transformado em promoção automática, na tentativa de destituí-la, com base nos resultados acerca da qualidade da educação básica das redes públicas do Estado de São Paulo, transparecidos, principalmente, a partir das avaliações externas e dos índices obtidos por elas
