Resumo


A disseminação de Fake News é um problema conhecido nas redes sociais. Uma das principais abordagens para detectar, automaticamente, este tipo de notícia é baseada na reputação, em especial a que utiliza Crowd Signals. Embora promissora, esta abordagem depende de informações nem sempre disponíveis: a opinião explícita dos usuários sobre as notícias serem fake ou não. Para superar esta desvantagem, este artigo propõe um método, baseado em Crowd Signals Implícitos, que não exige a opinião explícita dos usuários. Experimentos forneceram evidências de que o método proposto pode detectar Fake News sem exigir a opinião explícita dos usuários e sem comprometer os resultados obtidos pelo estado da arte dos métodos baseados em Crowd Signals.

Palavras-chave: Fake news, social media, crowd signals
