Abstract

Building ontologies is a complex and time consuming process. In this paper we present an approach for semi-automatic acquisition of relevant concepts and taxonomic relations among these concepts from texts. Our approach is based on those found in the literature but it aims to be suitable for Brazilian Portuguese written texts. This study is supported by a tool, and the results from a case study of application are briefly presented.
