Abstract :
A new scenario has raised into the IR field with the increase in the use of mark-up languages. This new scenario has been defined as structured IR and is focused on documents with structure. The classic IR models have been extended in order to be applied to this document type. Generally these adaptations have been carried out 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 weights applied to each 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 within a document.
