Extração e Validação de Ontologias a partir de Recursos Digitais

This paper aims at presenting a methodology for semi-automatic validation of an wide-coverage ontology based on an existing electronic resource, PAPEL. From the existing relations, we choose those of synonymy and hypernymy to generate the ontology. The resulting output was converted to OWL format e manually validated by a lexicographer. As result, we have a wide-coverage ontological resource th...

Biosynthesis of Erythrina alkaloids in Erythrina crista-galli.

A precursor application system was developed to allow the study of Erythrina alkaloid formation in Erythrina crista-galli. Fruit wall tissue of this species was recognized as the major site of alkaloid biosynthesis. The application of radioactively and 13C-labelled potential precursors showed that the hitherto assumed precursor (S)-norprotosinomenine was not incorporated into the Erythrina alka...
