摘要：Discute o termo “ontologia” sob a perspectiva da filosofia e da ciência da informação. Apresenta as raízes que constituíram o termo e a relação com o uso atual entre pesquisadores de áreas diversas, mas relacionado ao contexto computacional. Mostra uma definição formal de ontologia que utiliza recursos da lógica e da matemática essenciais para automatização de procedimentos computadorizados. Relaciona alguns modelos propostos para construção de ontologia e os consolida em uma visão que pode ser utilizada em sistemas de informação. Argumenta sobre a construção automática de ontologias a partir de textos como forma de viabilizar a produção de ontologias na velocidade requerida dos dias atuais e, assim, fornecer qualidade às estruturas de informações dispersas no mundo digital da Web. Palavras-chave Ontologia. Web semântica. Aprendizado de ontologia. Mineração de textos. Sistema de informação. From the text to ontology: a perspective for information science Abstract The objective of this paper is to discuss the term “ontology” with reference to Philosophy and Information Science. The rationale which constitutes the term is analyzed in relation to the present use by researchers of different areas, but always related to the computer context. A formal definition of ontology is presented by utilizing Logic and Mathematics, which are essential for automation of computerized procedures. Some models proposed are interrelated for construction of ontology and consolidation of a vision which can be used in Information Systems. Arguments are presented for the automatic construction of ontology from the text as a way of making the production of ontology feasible and as fast as required for the present days and so providing a quality to information structures spread out in the web digital world. Keywords Ontology. Semantic Web. Ontology learning. Text mining. Information system.
其他摘要：The objective of this paper is to discuss the term
“ontology” with reference to Philosophy and Information
Science. The rationale which constitutes the term is
analyzed in relation to the present use by researchers of
different areas, but always related to the computer context. A formal definition of ontology is presented by utilizing
Logic and Mathematics, which are essential for automation
of computerized procedures. Some models proposed are
interrelated for construction of ontology and consolidation
of a vision which can be used in Information Systems.
Arguments are presented for the automatic construction of
ontology from the text as a way of making the production
of ontology feasible and as fast as required for the present
days and so providing a quality to information structures
spread out in the web digital world.
