O trabalho de investigação sobre o tema 'Extração de dados com base em ontologias no conteúdo relacionado com bolsas de estudo' concentra-se na área das ontologias e na investigação dos métodos através dos quais os conceitos ontológicos podem ser reconhecidos no texto, reforçando o seu significado semântico. Nas experiências realizadas no domínio das bolsas de estudo, a ontologia para bolsas de estudo foi avaliada exaustivamente, e os nomes das disciplinas foram escolhidos como área-alvo para a investigação posterior sobre a recuperação de informação. A descoberta dos conceitos ontológicos no texto foi realizada, em primeiro lugar, através da recolha da página Web para a secção alvo e, em seguida, através da aplicação do método de pesquisa booleana com e sem pré-processamento prévio. Esta abordagem demonstrou resultados muito bons e, com o pré-processamento, foram recuperadas cerca de 70% das disciplinas. Além disso, foi proposta a extensão da ontologia como forma de aumentar a taxa de extração em 10%. Globalmente, 80% das disciplinas podem ser recuperadas pelo método proposto.
