Resumo


A análise de sentimentos tornou-se uma ferramenta essencial para aplicação em diversos contextos, incluindo análise de opinião do usuário sobre produtos e serviços, previsão durante campanhas políticas e até mesmo em tendências do mercado financeiro. Apesar do grande interesse neste tema e na quantidade de pesquisas na área, a maioria dos métodos foram projetados para funcionar com o conteúdo em inglês. Neste estudo, nos direcionamos a preencher esta lacuna propondo uma abordagem para o uso de determinados métodos estado-da-arte para análise de sentimentos em 9 diferentes línguas. Para isto, nós utilizamos bases de dados previamente rotuladas em cada idioma e uma simples tradução automática para o inglês e desenvolvemos uma metodologia para comparar e validar os resultados. Nossos resultados demonstram o potencial desta abordagem para tornar a análise de sentimentos independente da língua inglesa.
