O progresso da Web Semântica- ou Web 3.0 -, nos dias actuais, é um estímulo para o desenvolvimento de aplicações voltadas à partilha e integração de informação entre vários sistemas. Tantas podem ser as suas aplicações, em tão diferentes disciplinas, que a escolhida para este estudo emerge do universo pululante de unidades exploráveis. O presente trabalho tem como meta o desenvolvimento de uma ontologia para uma representação do domínio dos e-books utilizando as linguagens OWL e RDF, além do sistema Protégé para o seu desenvolvimento; a aplicação de técnicas de PLN para extracção de metadados de e-books, com a biblioteca NLTK; o desenvolvimento de uma aplicação para a realização de consultas à ontologia, com a linguagem SPARQL, visando a validação dos metadados; ABSTRACT: Nowadays, the progress of Semantic Web - or Web 3.0 - is a stimulus for the development of applications toward sharing and integration of information between various systerns. Their applications are as many as we can think, in several subjects, and, due to that, the one that I chose for this study emerges from the teeming universe of exploitable units. The present work has, as its aim, the development of an ontology for the representation of the domain of e-books, using the OWL and RDF languages, and the Protégé system for its development; the application of NLP techniques for the extraction of e-book metadata, using the NLTK library; the development of an application to query the ontology, using the SPARQL language, whose main goal is the validation of metadata.
