METODOLOGIA PARA A CONCEPÇÃO DE SISTEMAS DE RECUPERAÇÃO DE INFORMAÇÃO”

Abstract:
Propõe-se nesta dissertação uma metodologia para a concepção e construção de sistemas de IR, em particular no contexto do espaço distribuído e descentralizado que é a Web. Esta metodologia inclui uma linguagem de modelação (IRML-Information Retrieval Modelling Language), e baseada no mecanismo de extensão do UML e adequada às necessidades da Recuperação de Informação (IR). Para facilitar o processo de construção e promover a colaboração entre os investigadores de IR, é proposto um conjunto de bibliotecas padrão baseadas na linguagem IRML, no qual está embebido os principais conceitos da IR. Destas actividades resulta um conjunto de sistemas conceptuais que são implementados usando uma infra-estrutura adequada. Este conjunto de etapas permite simplificar o processo de construção de sistemas de IR. São construídos dez sistemas de IR ao qual se junta uma plataforma de teste onde são testados mais de mil sistemas num ambiente controlado. Esta plataforma permite testar processos existentes e outros construídos de raiz, nomeadamente novos processos de comparação híbridos, novas fórmulas de seguimento de ligação, pseudo-retroacção e de combinação de resultados.
