\textoresumo[english]{This study explores the dynamics of echo chambers and polarizing behavior within the Colab social network, employing an innovative approach with quantitative metrics combinint sentiment and network analysis. Using the communities of Niterói, Santo André, and Mesquita as case studies, Colab is examined as a hyperlocal social barometer that reflects the social pressures exerted by users at a hyperlocal level.

Combining network analysis, sentiment analysis, and user persona classification, we developed a model that identifies patterns of polarization and echo chambers, proposing interventions to mitigate these phenomena and strengthen the diversity and quality of public debate.

The results demonstrate the existence of highly polarized subgroups and the significant impact of algorithmic curation and user behavior on the structuring of Colab's informational ecosystem. We propose heuristics for the detection of echo chambers and operational strategies for social network administrators, aiming to promote a more inclusive democratic engagement and to improve participatory governance.
The work concludes by reflecting on the broad implications for participatory governance and the challenges of encouraging democratic engagement in a polarized digital media environment, emphasizing the importance of balancing technology and human oversight.}{Social Network Analysis; Echo Chambers; Graph Theory}

Em resumo, a pesquisa adota uma estratégia de fases interdependentes, em que os resultados de cada experimento alimentam o próximo, ampliando nosso entendimento das dinâmicas da rede Colab e das câmaras de eco presentes nesse ambiente

\section{Universo e Amostra}

Para a realização deste estudo, foram empregados dados providenciados pela equipe de Pesquisa e Desenvolvimento do Colab, abrangendo um universo significativo de 57.801 usuários ativos. O período de análise estende-se de Março de 2013 a Maio de 2022, proporcionando uma visão longitudinal do comportamento dos usuários e da evolução da rede. As cidades de Caruaru, Rio de Janeiro e Recife foram incluídas na análise para fornecer uma compreensão amplificada da topologia da rede e dos padrões de interação em diferentes contextos urbanos e demográficos.

Especificamente, o estudo concentrou-se com maior intensidade nas cidades de Niterói, Mesquita e Santo André, pois essas localidades apresentaram o maior volume de interações dentro da plataforma. A escolha dessas cidades como foco principal permite um exame detalhado das dinâmicas de interação que podem ser cruciais para a compreensão de fenômenos sociais complexos mediados pela plataforma.

Dentro da amostra selecionada, foram registradas 329.694 eventos e 334.682 comentários, totalizando 801.792 interações que servem como uma base robusta para análises subsequentes. Estes dados refletem a rica troca de informações e o engajamento dos usuários com o aplicativo, constituindo um campo fértil para investigações sobre a formação de comunidades, disseminação de informações e construção de consenso dentro do ambiente digital.

\section{Coleta de Dados}

Os dados analisados foram gentilmente disponibilizados pelo Colab em formato CSV, permitindo a manipulação e análise direta. Incluídos neste conjunto de dados estão as listas de arestas, que ilustram as relações entre os usuários, e uma série de atributos relacionados às atividades dos usuários na plataforma, tais como interações, postagens, além de informações demográficas e geográficas relevantes para o estudo. Importante ressaltar que os dados foram devidamente anonimizados para garantir a privacidade dos usuários, removendo quaisquer identificadores pessoais. Discutimos esse processo em \autoref{sec:anonimizacao}. A estruturação dos dados e os procedimentos de pré-processamento aplicados estão descritos no \autoref{sec:modelo_de_dados}, garantindo a transparência e a reprodutibilidade das análises realizadas.


\section{Procedimentos de Análise}

\begin{itemize}
\item \textbf{Análise de Redes Sociais:} Utilizando técnicas de ciência de dados e análise de grafos para identificar estruturas e características da rede Colab.
\item \textbf{Classificação de Usuários:} Serão empregadas técnicas de processamento de linguagem natural e aprendizado de máquina supervisionado para classificar postagens e comportamentos dos usuários.
