Defende-se como tese que quanto maior o nível de comprometimento de uma determinada comunidade, maiores as possibilidades da inteligência coletiva resultar em produção de conteúdo; quanto mais possibilidades de produção objetiva de conteúdo, maior a presença direta da Ciência da Informação, e quanto menos produção objetiva de conteúdo mais desafiadora é a atuação dessa ciência, uma vez que sua atenção será sobre os processos de informação. Dessa forma, pretende-se propor um arcabouço epistemológico para a reflexão da inteligência coletiva no âmbito dos estudos em Informação e Tecnologia. Para tanto, a partir de uma pesquisa exploratória, conduzida pelo aspecto bibliográfico, o estudo se propôs a investigar as diferentes manifestações da inteligência coletiva - o compartilhamento, a cooperação e a ação coletiva; definir um modelo para a análise de ambientes digitais que aparentam a cultivação da inteligência coletiva; compreender a trajetória evolutiva dos ambientes digitais que tiveram como foco a inteligência coletiva; analisar, mediante ao modelo criado, os ambientes digitais definidos. Os ambientes selecionados para análise foram o YouTube, Facebook e a Wikipédia. Observou-se que as manifestações analisadas são variáveis que compõem a inteligência coletiva, e que ...

It is defended as thesis that the greater the level of commitment of a determined community, the greater the possibilities of the collective intelligence result in the objective production of content; the more possibilities of objective production of content, the greater the direct presence of Information Science, and the less objective production of content more challenging is the performance of this science, since its attention will be on information processes. In this way, its intend to propose an epistemological framework for the reflection of collective intelligence in the scope of studies in Information and Technology. To do so, based on an exploratory research, steering by the bibliographical aspect, the study proposed to investigate the different manifestations of collective intelligence - sharing, cooperation and collective action; to define a model for the analysis of digital environments that appear to cultivate collective intelligence; to understand the evolutionary trajectory of digital environments that focused on collective intelligence; to analyze, through the created model, the defined digital environments. The environments selected for analysis were YouTube, Facebook, and Wikipedia. Its observed that the analyzed manifestations are variables that make up the ...

M.Sc. (Information Technology) / A new particle swarm optimisation (PSO) algorithm that produces solutions to the xed spectrum frequency assignment problem (FS-FAP) is presented. Solutions to the FS-FAP are used to allocate frequencies in a mobile telecommunications network and must have low interference. The standard PSO algorithm's velocity method and global selection is ill suited for the frequency assignment problem (FAP). Therefore using the standard PSO algorithm as base, new techniques are developed to allow it to operate on the FAP. The new techniques include two velocity methods and three global selection schemes. This study presents the results of the algorithm operating on the Siemens set of COST 259 problems and shows that it is viable applying the PSO to the FAP.

This thesis is focused on realization of the swarm intelligence experiments in the simulation software Vortex and MRDS. The aim is to decide whether the achieved results meet the theoretical expectations based on the published experiment.

This work deals with two optimization problems, traveling salesman problem and cluster analysis. Solution of these optimization problems are applied on INVEA-TECH company needs. It shortly describes questions of optimization and some optimization techniques. Closely deals with swarm intelligence, strictly speaking particle swarm intelligence. Part of this work is recherché of variants of particle swarm optimization algorithm. The second part describes PSO algorithms solving clustering problem and traveling salesman problem and their implementation in Matlab language.
