Funciones de Ranking basadas en Lógica Borrosa para IR estructurada

With the increase in the use of mark-up languages, a new scenario has raised into the IR field; this new scenario is focused on structured documents, and has been defined as structured IR. The classic IR models have been extended in order to be applied to this new scenario. Generally these adaptations have been carried on by weighting the fields that form the document structure, and making the assumption of statistics independence between fields. This assumption force to an estimation of the different boosts applied to every field. In this paper a new ranking function for structured IR is proposed. This new function is based on Fuzzy Logic, and its main aim is to model through heuristics and expert knowledge the relations between fields.
