Resumo

Tumores Cerebrais são responsáveis por um percentual significativo dos tipos de câncer em adultos e crianças. Pacientes com tumor cerebral sofrem diversos sintomas como convulsão, dor de cabeça, náusea, estresse entre outros. Muitos desses sintomas são oriundos dos severos tipos de tratamentos que o paciente é submetido tais como cirurgia, quimioterapia e radioterapia. Na era contemporânea, o paciente, familiares, amigos e profissionais de saúde buscam na internet, particularmente, nas redes sociais, informações sobre a sua doenca. As redes sociais são comunidades virtuais onde seus membros e pares trocam informações entre si e onde grupos virtuais são formados para a discussão de temas específicos. Entre as redes sociais existentes, o Facebook é o mais famoso, com um bilhão de usuários conectados/dia em 2015. Entretanto, apesar da abundância de informações contidas nessa mídia, há uma carência de trabalhos científicos que avaliem o volume e o tipo de informação sobre tumores cerebrais contidas nas redes sociais. Assim, o objetivo deste trabalho é realizar uma análise quantitativa das informações sobre tumores cerebrais postadas em grupos de discussão do Facebook destinados a esse tema. O propósito é identificar, a partir da frequência de termos, quais são os assuntos abordados nas postagens, além de captar a percepção dos usuários sobre a utilidade das informações publicadas. O trabalho também apresenta um panorama geral dos grupos de discussão existentes e do volume de mensagens trocadas entre seus membros. A fim de atingir os objetivos estabelecidos, uma metodologia de coleta e análise das informações sobre tumor cerebral contidas nas postagens de grupos da rede social Facebook foi criada. O framework Hadoop/Mapreduce e a ferramenta Graph API foram utilizados como tecnologia para coletar, selecionar, armazenar e analisar (tipo e volume) o conteúdo das postagens. Um questionário eletrônico foi usado para medir a percepção do usuário sobre a utilidade das informações postadas. A análise de conteúdo e volume foi realizada pela frequência de termos e os resultados obtidos foram apresentados em forma de gráficos. Os termos mais frequentes, tais como, steroid compound, chemotherapy, doctor e seizure mostram que os tema mais abordados nas postagens são os tratamentos convencionais para o câncer, os profissionais envolvidos e os sintomas dos pacientes. O questionário de avaliação de percepção mostrou que 95% dos usuários afirmam ter encontrado informações úteis sobre tumor cerebral nas postagens da rede social. Os resultados permitem concluir que existe uma quantidade significativa de dados importantes sobre tumor cerebral no Facebook e que o seu uso como uma potencial fonte auxiliar de informação deve ser considerado.
