Comparativo entre fontes de dados para anotação automática de videoaulas
Resumo
A facilidade de criação de conteúdos digitais tem permitido que repositórios de recursos educacionais possam crescer rapidamente, gerando necessidade de melhores mecanismos de indexação e busca. Para usuários, ainda há muita dificuldade de encontrar vídeos de interesse quando estes possuem metadados de baixa qualidade. O processo de atribuir novos descritores aos vídeos é chamado de anotação. Este trabalho tem como objetivo explorar as fontes de informação presentes em videoaulas que podem auxiliar no processo no anotação semântica. O artigo apresenta uma análise comparativa entre a qualidade dessas fontes de dados de forma a demonstrar quais fontes geram melhor resultado para o processo de anotação.
Palavras-chave:
