Composite spatial objects and relationships and taking the wave into account to interpret an indirect spatial referencing

This paper proposes a methodology for transforming a position description expressed relatively in an indirect spatial reference system into an absolute position in a direct spatial reference system. This problem requires (1) to formalize the relative location elements, here in the form of a triplet model, which is used as a basis for the transformation from relative to absolute position, and (2) to investigate how the imperfection of the natural language can be taken into account in the modeling process. We propose to use fuzzy spatial objects and we will compare their implementations to identify the most appropriate approach to our context.
