|Abstract:||Let Q be a finite set of problems. A knowledge state is the set
of problems a person is capable of solving. A family K of knowledge
states is called a knowledge structure, if the empty set and Q are
elements of K. When K is closed under union, the structure is called
a knowledge space. There exist effective algorithms to generate a
knowledge space by querying an expert using an entail relation.
In this note, we show that more general knowledge structures can be generated using modified query procedures. The general theory of the Galois connections between entail relations and knowledge structures is explored. Finally, we present query procedures which can be applied to generate any knowledge structure.
