title: Visual and conceptual hierarchy: a paradigm for studies of automated generation of recognition strategies.
abstract: The purpose of this correspondence is to show the design considerations in the choice of mechanisms when a flexible querysystem of visual scenes is being constructed. More concretely, the issues are: ¿ flexibility in adding new information to the knowledge base; ¿ power of inferencing; ¿ avoiding unnecessary generation of hypotheses where a great deal of image processing has to be perfected in order to test it; ¿ having the power of automatic generation of recognition strategies.
