Estudo e análise de associações de conceitos a partir de fonte não estruturada

Abstract

In this paper is realized a case study with the use of a mostly unstructured source about the nutritional diseases theme, in order to support queries of relations between concepts not explicitly related in the used source. Initially the relevant concepts from the interest theme are chosen, then the binary relations between these concepts are manually extracted. In order to support the queries of chained concepts, an ontology was built in which are represented association relations, manually extracted from the unstructured source, completed by specialization relations from the WordNet and missing association relations from an additional source. The created ontology made possible to automate the queries of chained association relations, resulting in the interconnection of concepts that weren’t explicitly associated in the unstructured source.
