Anotação de relações semânticas em Objetos de Aprendizagem com o paradigma Open IE

Abstract: The Semantic Web technologies enable the semantic annotation of Learning Objects (LO), which could help the search and retrieval of LO. However, the LO manual semantic annotation is a high-cost, mentally demanding, and, usually, a domain-dependent task. Thus the present work proposes a model for automatic semantic annotation of LO in Portuguese using ontologies and the Open Information Extraction (Open IE) paradigm. We also conducted an empirical study, in which the model implementation was able to annotate se… Show more

“…Bezerra et al (2017) describe the PUYW ontology, which takes the user's preferences regarding YouTube videos, channels and playlists, as well as Wikipedia texts, into consideration to base the Youubi recommendation system's decisions. Sanches et al (2019) highlight the difficulty of manual semantic annotation and propose an automatic annotation algorithm based on the Open Information Extraction paradigm (Open IE) presented by Etzioni et al (2008). Phiakoksong et al (2013) used the Structural Modeling Equation, a statistical technique that explores main concepts and their relationships obtained in empirical data, in order to build an ontology with good teaching practices.…”
