Summary: This work presents a comparative analysis between the main approaches used at the task of Extraction of Aspects in reports about products and services on web sites. Adaptations of four methods of extraction of aspects were implemented and evaluated using two distinct Corpora, one in Portuguese and another in English. On the experiments performed it was observed that the approach using supervised learning (convolutional neural networks) obtained better results on the others.

Adaptações de quatro métodos de extração de aspectos foram implementadas e avaliadas usando dois Corpora distintos: um em português e outro em inglês. Nos experimentos realizados foi observado que a abordagem usando aprendizagem supervisionada (redes neurais convolucionais) obteve melhores resultados que as demais.Sociedade Brasileira de Computação2020-06-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://journals-sol.sbc.org.br/index.php/isys/article/view/79610.5753/isys.2020.796iSys - Revista Brasileira de Sistemas de Informação; v. 13 n. 3 (2020); 82-97iSys - Brazilian Journal of Information Systems; Vol. 13 No. 3 (2020); 82-971984-290210.5753/isys.2020.3reponame:Brazilian Journal of Information Systemsinstname:Sociedade Brasileira de Computação (SBC)instacron:SBCporhttps://journals-sol.sbc.org.br/index.php/isys/article/view/796/742Copyright (c) 2020 iSys - Brazilian Journal of Information Systemsinfo:eu-repo/semantics/openAccessVieira, João Paulo AlbuquerqueMoura, Raimundo Santos2020-07-06T19:34:52Zoai:journals-sol.sbc.org.br:article/796Revistahttps://journals-sol.sbc.org.br/index.php/isys/ONGhttps://journals-sol.sbc.org.br/index.php/isys/oaipublicacoes@sbc.org.br1984-29021984-2902opendoar:2020-07-06T19:34:52Brazilian Journal of Information Systems - Sociedade Brasileira de Computação (SBC)false
