% Problem  : What does Sue feel?
% Version  : Especial.
% English  : Mary likes Bill and Sue likes Bill. During 2009 Sue did not like 
%            Ben. Are there a relation ?P and persons ?X and ?Y, so that 
%            during the year 2009 ?P holds for Sue and ?X but ?P does not hold 
%            for Sue and ?Y.

% Comments : This is a simple test problem for reasoning in/about SUMO.
%            Initally the problem has been hand generated in KIF syntax in
%            SigmaKEE and then automatically translated by Benzmueller's
%            KIF2TH0 translator into THF syntax.
%          : The translation has been applied in two modes: local and SInE.
%            The local mode only translates the local assumptions and the
%            query. The SInE mode additionally translates the SInE-extract
%            of the loaded knowledge base (usually SUMO).
%          : The examples are selected to illustrate the benefits of
%            higher-order reasoning in ontology reasoning.
