Current projects

2002 a AtualCNPq - Bolsa de Produtividade em Pesquisa, nível 1A "Ambientes para Recuperação de Informação na WWW", início em 1984.
Esta é uma proposta de pesquisa e desenvolvimento na área de ambientes para recuperação de informação na WWW (World Wide Web). A WWW se converteu nos últimos anosno meio que permite o intercâmbio massificado de informação ao redor do mundo. O seu uso intensivo gera cada ve mais um volume de intercâmbio de informação tal que os métodos existentens começam a mostrar-se limitados para recuperação eficiente neste novo cenário de utilização.
Integrantes: Nivio Ziviani (coordenador).
