Abordagens para Estimar Relevância de Relações Não-Taxonômicas Extraídas de Corpus de Domínio

This paper performs a comparison between two approaches to weight the relevance of extracted non-taxonomic relations found in domain corpora. The first approach computes the relevance according to the verb absolute frequency. The second approach computes the relevance according to the verb frequency and uniqueness in each corpus using tf-dcf relevance index, an index that takes into account the...

Expression of Leucaena Leucocephala de Wit Chitinase in Transgenic Koshihikari Rice

The cDNA encoding the 326 amino acids of a Class I basic chitinase gene from Leucaena leucocephala de Wit (KB3, Genbank accession: AAM49597) was cloned under the control of CaMV35S promoter in pCAMBIA 1300 and transferred to Koshihikari. Calli of Koshihikari rice was transformed with agrobacterium with this construct expressing the chitinase and βglucouronidase (GUS). The frequencies of calli 9...
